PLASTICISER FOR SEALANTS, PLASTISOLS AND ADHESIVES
FIELD OF THE INVENTION
Thc invention relates to a composition of hydrocarbon-containing
5 fluids that can be used as a plasticizer in the formulation of mastics,
plastisols and adhcsives.
The present invention relates to a plasticizer without phthalates, with
a low content of volatile organic compounds (or VOCs) and also partly
comprising compounds of renewable origin.
10 The present invention also relates to the use of said composition for
the formulation of mastics, plastisols and adhesives.
TECHNICAL CONTEXT OF THE INVENTION
Numerous products are used in construction materials, for example
for floor coverings, mastics or also sanitary seals. The addition of plasticizers
15 is common in certain families of mastics such as the hybrid mastics (based
on silyl modified polymers), acrylic mastics, polyurethane mastics, plastisols
(PVC paste) and certain adhesives. A plasticizer is a molecule or an oligomer,
in the solid state or in the more or less viscous liquid state, added to the
formulations of different types of materials in order to make them more
20 flexible, more resistant, more resilient or easier to handle.
An ideal plasticizer is compatible with the polymer matrix in order to
prevent migration phenomena, has low volatility, can be extracted only with
difficulty by the liquids that will be in contact with the plasticized material, it
performs well with regard to certain properties such as flexibility, resistance
25 to impact, cold, heat and has good electrical resistivity. It does not beceme
oxidized and remains non-toxic, odourless, colourless and inexpensive.
The phthalates are products very commonly used as a plasticizer. But
the pressure of increasingly stringent regulations restricts their uses in
many countries due to their danger to human health. Alternatives to their
30 use are now therefore necessary and much sought-after.
On the other hand, recent regulatory constraints imposed by
limitations on volatile organic compounds or VOCs in construction materials
are also to be taken into account. In fact, these compounds have a tendency
to evaporatc and/or degrade either immediately or over time and to be a
35 source of emissions that are often toxic to the environment and more
particularly to human and animal health. These emissions effecting everyday
life constitute a significant source of pollution inside homes, offices and
administrative buildings and any closed space with limited ventilation. These
emissions may be greatest when the materials are applied, but there may
also be a longer-term effect due to residual volatility over time or even linked
to the gradual degradation of the covering or of the adhesive or mastic
composition.
5 Hydrocarbon-containing fluids of the gas oil, kerosene or white spirit
type can also be used as a secondary plasticizer in different formulations
including polymers or resins. This is the case for the mastics or PVC pastes.
But their use is now limited by their lower compatibility in the polymer
compared with phthalates. Phenomena of surface migration, bleeding, and
10 surface appearance defects that have been noted prevent the production of
formulik 'without phthalates containing only hydrocarbon-containing fluids.
Due to the increasing regulatory constraints, a technical solution is
required in order to allow the replacement of the phthalates in stable and
economically advantageous formulations of construction materials with a
15 low VOC content.
Onc of the main objectives of the applicant is therefore to propose a
composition that can be used as a phthalate-free plasticizer, for the
formulation of construction materials and materials intended for the
automotive sector such as mastics, plastisols or certain types of adhesives.
20 Another of the objectives of the applicant is to obtain a composition
that can be used as a plasticizer with non-VOC properties, for the
formulation of construction materials, materials based on resins or materials
used in the automotive sector such as mastics, plastisols or certain types of
adhesives.
25 Another objective of the applicant is to propose a composition that can
be used as a plasticizer compatible with use for the formulation of mastics,
plastisols and adhesives.

be used as a plasticizer allowing the formulation of mastics, plastisols and
30 adhesives having satisfactory hardening, in particular according to the
standard DIN IS0 76 19 (for mastics).
Another objective of the applicant is to propose a composition that can
be used as a plasticizer allowing the formulation of mastics, plastisols and
adhesives which exhibit no bleeding.
35 Another objective of the applicant is to propose a composition that can
be used as a plasticizer allowing the formulation of mastics, plastisols and
adhesives having satisfactory drying, i.e. drying in less than 24 hours for a

Preferably, the feedstock obtained after the distillation stage or stages
is a gas oil feedstock, this gas oil feedstock being subjected to the stages of
hydrotreatment, hydrocracking, catalytic cracking or hydrodewaxing,
optionally followed by stages of de-aromatization and optionally of
5 desulphurization.
The hydrocarbon-containing cut can be a mixture of hydrocarboncontaining
cuts subjected to the stages described above.
The hydrocarbon-containing cut as described above, has a distillation
range DR (in "C) such that 230 I DR < 400 and more preferably such that
10 250 DR I 380. The hydrocarbon-containing cut can comprise one or more

comprised between -30 and - 10°C.
The cut originating from biomass conversion can be produced from
biological raw materials selected from the group consisting of vegetable oils,
animal fats, fish oils and mixtures thereof. The appropriate biological raw
materials comprise the following: oil from oilseed rape, canola oil, rapeseed
oil, tall oil, sunflower oil, soya oil, hemp oil, olive oil, linseed oil, mustard oil,
palm oil, groundnut oil, castor oil, coconut oil, animal fats such as pig fat,
5 tallow or flare fat, recycled edible fats, raw materials originating from genetic
engineering and biological raw materials produced by microorganisms such
as algae and bacteria. Condensation products, esters or other derivatives
obtained from raw biological materials can also serve as raw materials.
A solvent 'of biological origin is then produced using for example a
10 process which comprises firstly a stage of hydrodeoxygenation (HDO) in
order to break down the structure of the constitutive biological esters or
triglycerides and in order to remove the compounds containing oxygen,
phosphorus and sulphur whilst at the same time producing the
hydrogenation of the olefinic bonds. This is followed by isomerization of the
15 product thus obtained leading to the branching of the hydrocarbon chain
and to an improvement in the properties of the paraffin at low temperatures.
It is for example possible to fractionate the product in order to obtain the
desired cuts.
The hydrocarbon-containing cut according to the invention also has
20 the advantage of being easily available on the market, being relatively

products.

fatty acids) with an alcohol. During the esterification or transesterification,
small quantities of fatty acids may remain in the form of monoglyceride,
30 diglyceride, triglyceride or of fatty acids in the free form.

alkyl monoester, such as a methyl monoester, an ethyl monoester, an npropyl
monoester, an i-propyl monoester, an n-butyl monoester, an s-butyl
monoester, a t-butyl monoester. Preferably, the monoester is a methyl
