DESC:FIELD OF THE INVENTION

The present disclosure relates to a powder formulation for waterproofing membrane and a process of preparing thereof.

BACKGROUND OF THE INVENTION

In the dynamic landscape of the construction industry, where structural integrity is paramount, the role of waterproofing cannot be overstated. It serves as a crucial element in prolonging the life of structures and shielding them from the deleterious effects of water-induced concrete and reinforced steel degradation. Recognizing the significance of this, Fibrex has undertaken an extensive research initiative to develop an innovative powder material that not only addresses the pervasive need for waterproofing but also boasts compatibility with a myriad of construction surfaces, both new and old.

The culmination of years of dedicated research efforts has resulted in Fibrex's groundbreaking powder material. This proprietary substance exhibits unparalleled waterproofing properties, presenting a versatile solution for a multitude of application areas within the construction industry. Whether it be sunken structures, basements, roofs, or water-retaining elements in buildings and concrete structures, Fibrex's powder material stands as a testament to advancements in construction waterproofing technology.

Within the realm of waterproofing methodologies, the invention draws attention to sheet-like waterproofing membrane laminates, a well-established approach for applications on concrete and various substrates. Typically comprising a carrier sheet and a pressure-sensitive adhesive layer, these laminates have found widespread use. In one application method, the waterproofing sheet material is applied to an already cured concrete surface, such as a building foundation, with the adhesive layer bonding to the concrete. Another technique involves affixing the waterproofing membrane to the concrete form or lagging, where the carrier sheet faces the lagging, and the adhesive portion is oriented towards the cavity where concrete will be poured. Referred to as "blind side" or pre-applied waterproofing, this process results in the adhesive portion adhering to the freshly poured concrete, creating a fully adhered waterproofing membrane on the cured concrete surface post-lagging removal.

Moreover, the versatility of Fibrex's powder material is evident in its application on horizontal surfaces. Whether applied to compacted soil, gravel, or a concrete slab, with the adhesive portion facing upward, this material offers a unique solution. Concrete can then be cast against the membrane, creating a comprehensive waterproofing system.

In one solution, a waterproofing membrane includes laminated layers: layer A comprising a waterproofing adhesive; layer B comprising a carrier sheet; layer C comprising a releasable bonding material; and layer D comprising a protective coating; wherein (i) the laminated layers are arranged in the sequential order A-B-C-D; or (ii) the laminated layers are arranged in the sequential order B-C-D-A; or (iii) the laminated layers are arranged in the sequential order C-D-A-B. The membrane does not include a removable release sheet that is typically used to prevent the adhesive from adhering to the carrier sheet or other portion of the membrane when the membrane is rolled up. Also disclosed is a method of making the aforementioned membrane. Preferably, layer C will comprise a water-soluble polymer, an alkali-soluble polymer, or a homopolymer or copolymer of polyvinyl acetate.

In another solution, a membrane comprising a barrier layer comprising a thermoplastic polymer component and a contact layer bonded to at least a portion of the barrier layer, the contact layer comprising a mixture of a solid filler component and a thermoplastic polymer component. The disclosure is also directed to a method for producing the membrane, a method for waterproofing a substrate, a waterproofed construction, a method for sealing a substrate against water penetration, and a sealed construction for sealing a substrate against water penetration.

In the view of the forgoing discussion, it is portrayed that in the prior arts, membranes become soft and easily mesh with a hand at low temperatures. Therefore, there is a need to develop a waterproofing membrane formulation with High crack bridging, High adhesion, and High water pressure resistance.

SUMMARY OF THE INVENTION

The present disclosure relates to a powder formulation for waterproofing membrane and a process of preparing thereof. The waterproofing membrane is a high-performance, single-component PMMA & acetate hybrid waterproofing system. It is spray applied in a sandwich structure between two layers of sprayed concrete/cast concrete layers creating a double bonded composite shell lining. It is an effective alternative to conventional waterproofing sheet membranes. As a double-bonded system, this provides excellent water tightness, preventing the development of water migration on both sides of the membrane. The invention further relates to a waterproofing material obtainable by adding water to such dry powder composition and a substrate coated with a FIBELASTIC PLT layer deposited from such waterproofing material.

In an embodiment, a dry powder composition for waterproofing membrane comprises 0.1% to 5% by weight of cement, 2% to 4% by weight of aluminous cement, 2% to 4% by weight of sulfate aluminate cement, 40% to 80% by weight of dispersible binder polymer particles, 0.01 to 0.5% by weight of cellulose ether, 0.5 to 1% by weight of chile saltpeter, 0.2 to 4% by weight of inorganic defoamer, 1.3 to 10% by weight of calcium carbonate, 1 to 5% by weight of oxide pigment, and 20% to 30% by weight of silica sand.

In another embodiment, a process of preparing powder formulation for waterproofing membrane includes collecting raw materials thereby stacking them in bags, the raw material comprises 0.1% to 5% by weight of cement.
The process further includes feeding of raw material to a pneumatic conveying system achieved by bag slitting machines, an electric hoist, and a bag massager system.

The process further includes blending and mixing the raw material and ingredients using a blender/mixer received from the charge hoppers through a screw conveyor for formulating powder formulation for the waterproofing membrane.

The objective of the present invention is to provide waterproofing material that is cheap, reliable, easy to use, and suitable for almost all substrates like concrete, metals, boards, etc., and areas like sunken, roofs, basements, retaining structures, etc.

The present invention provides a waterproofing layer-like barrier to water penetration. One of the advantages of this product, it can withstand a negative temperature without losing its mechanical properties.

Manufacturing Process:
The major ingredients of the membrane are vinyl acetate base polymer powder & minerals fillers in fixed quantities along with other minor ingredients.
The manufacturing process can be done in 5 steps
1. Taking raw materials from storage
2. Weighing of the ingredients
3. Conveying raw material to charge hoppers
4. Blending & mixing
5. Testing Correction, packing and storage
1. Taking of raw materials from storage: Raw materials stacked in small bags of 25 kg & 50 kg after tested ok. Unloading of these bags and feeding of raw material to the conveying system shall be achieved by bag slitting machines for small bags and with an electric hoist & bag massager system in case of big bags. Depending upon the finished product, the quantity of raw material can be decided. First, the bulk quantity of raw material is transferred to storage silos. For transferring the material to silos, a pneumatic conveying system is preferred as it is economical and robust, both in operation as well as maintenance.
2. Weighing of the ingredients: The ingredients should be added in exact proportions (determined by formula) to ensure producing premium quality. Therefore, a hopper with weighing cells must be located below the storage silos. Metering of the raw material from the silo to weigh hopper should be performed by screw conveyors. After getting the right quantity of material in the weighing hopper, it will be dosed to charge the hopper by conveying line via rotary airlock valves.
3. Conveying of raw material to charge hoppers: The raw material must now be conveyed to charge hoppers as per requirement. The selection of charge hoppers is done with the help of diverters in the conveying line. Conveying capacity is decided by the blender batch cycle time. Based on capacity requirement & distance, conveying air is calculated & a blower is selected.
4. Blending & mixing: After the material is charged in a charge hopper, it gets dosed in a blender/mixer with the help of a screw conveyor. The average blender mixing time is between 15-30 minutes.
5. Testing Correction & Packing: After mixing a small quantity is checked in the lab and if any correction needs the lab in-charge corrects it and then the material is transferred to the packing machine where it is duly packed. The final product is then moved to the finished goods storage area. All the system operations can be controlled through a PLC panel. Using PLC programming, the system measures the accuracy of various raw materials mixed in the ingredients, thus delivering superior quality. Consequently, it also reduces labor intensity in addition to environmental pollution.
The product has a high quantity of very flexible copolymer of vinyl acetate and ethylene that provides the properties of adhesion and flexibility at a wide range of temperatures. Redispersible polymer powders are polymer emulsions that have been converted by a series of processes such as high temperatures and pressures, spray drying, and surface treatment to powdered thermoplastic resin materials. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer emulsions.
Redispersible Polymer powder (ordinary type) is composed of special polymers made of powder adhesive after spray drying. This powder is in contact with water and can be dispersed again soon after forming an emulsion, and with nature the same as the initial emulsion, namely the film can be formed after moisture evaporation, the film has high flexibility, high resistance to weathering, and on various substrate with high caking property. It can improve the performance of the waterproofing membrane, raise the bonding strength of the waterproofing membrane with the different substrate materials, and improve flexibility. Feature: Redispersible Polymer powder is the main raw material in the production of Waterproofing membranes.
Redispersible Polymer powder has obvious functions in the dry-mixed waterproofing membrane. It can improve strength and bonding force, the elastic bending strength. It also improves the freeze-proof property, weathering resistance, durability, and wear resistance of the materials. As well as intensify the hydrophobicity and reduce the water absorption, improve the construction characteristics. The powder can efficiently prevent water penetration.

1. Improvement of the bonding strength and bonding force: It is quite necessary to add Redispersible Polymer powder to the products of waterproof powder material. It can improve the bonding strength and bonding force of materials. Furthermore, due to the fine bonding force of polymer resin, the powder has better effects on improving the bonding force of the waterproofing membrane to the basis materials.
2. Improvement of the tensile property: Redispersible Polymer powder increases the tensile property due to its interbonding properties.
3. Improvement of the hydrophobicity and reduction of the water absorption: The addition of the Redispersible Polymer powder can improve the microscopic structure of the waterproofing membrane. The polymer forms the irreversible network during the curing process.
4. Improvement of the freeze-thawing stability and efficient prevention of the cracking of materials: The plasticity function possessed by the thermoplastic resin of Redispersible Polymer powder can overcome the flatulence damage for waterproofing materials brought by temperature difference changes.
The waterproofing membrane base of a copolymer of vinyl acetate and ethylene provides the properties of adhesion and flexibility at a wide range of temperatures. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer emulsions. After application, it became a waterproofing material, which resists the penetration of water.
