[2] This application relates to a resin composition. Specifically, the present application relates to a resin composition, a battery module including a cured product of the resin composition, a method of manufacturing a battery module, a battery pack, and a vehicle. Background [3] The secondary battery includes a nickel cadmium battery, a nickel hydride battery, a nickel zinc battery, or a lithium secondary battery, and a representative one is a lithium secondary battery. [4] Lithium secondary batteries mainly use lithium oxide and carbon materials as positive and negative active materials, respectively. A lithium secondary battery includes an electrode assembly in which a positive electrode active material and a negative electrode active material are applied, respectively, and an electrode assembly in which a negative electrode plate is disposed with a separator interposed therebetween, and an exterior material for sealing and receiving the electrode assembly together with an electrolyte. And pouch-type secondary batteries. This single secondary battery may be referred to as a battery cell. [5] In the case of a medium or large-sized device such as a vehicle or a power storage device, a battery module in which a large number of battery cells are electrically connected to each other may be used to increase capacity and output, or a battery pack in which a plurality of such battery modules are connected may be used. [6] One of the methods of configuring a battery module or a battery pack as described above is to use an adhesive material capable of fixing a plurality of battery cells inside the battery module. In this case, the adhesive material may be injected into the battery module through an injection hole formed on the surface of the battery module. Detailed description of the invention Technical challenge [7] An object of the present application is to improve injection processability and prevent overloading of injection equipment in a resin composition that can be used to fix a battery cell in a battery module. [8] Another object of the present application is to provide a composition capable of providing excellent insulation, adhesion, heat generation, etc. after being injected into a battery module and cured. [9] Another object of the present application is to provide a battery module, a manufacturing method, and a battery pack including a cured product of the resin composition. Means of solving the task [10] In an example related to the present application, the present application relates to a resin composition used in a battery module or battery pack. Specifically, the composition of the present application may be a composition injected into the case of the battery module and used to fix the battery cell in the battery module by contacting one or more battery cells present in the battery module, as described below. . [11] In this regard, the resin composition, for example, the adhesive composition may include a main resin and a curing agent, and may be a resin composition satisfying the following General Formulas 1 and 2. [12] [General Formula 1] [13] 10 ≤ Initial load value (Li) ≤ 40 [14] [General Formula 2] [15] 1 ≤ load change rate (Lf/Li) ≤ 3 [16] In the general formulas 1 and 2, Li is the initial load value (kgf) measured immediately after the main resin and the curing agent are mixed, and Lf is the aging load value (kgf) measured after 3 minutes after the main resin and the curing agent are mixed. , The load values ​​Li and Lf each represent the maximum value of the force required when discharging the resin composition at a constant speed through a mixer having a constant cross section. [17] In the present application, the term "room temperature" is a state that is not particularly heated, and any temperature within the range of about 10°C to 30°C, for example, about 15°C or more, 18°C ​​or more, 20°C or more, or about 23°C It is above and may mean a temperature of about 27°C or less. Among the physical properties mentioned in the present specification, when the measured temperature affects the physical properties, the physical properties may be those measured at room temperature unless otherwise stated. [18] In the present application, the initial load value (Li) measured immediately after the main resin and the curing agent are mixed is injecting the main resin and the curing agent into two cartridges to be described later, and pressing at a constant speed of 1 mm/s with a pressing means to be described later. , The main resin and the curing agent are injected into a mixer to be described later, and the force required for the pressurizing means is measured from the first discharge after mixing in the mixer, and the maximum value is set at the point where the force becomes the maximum value. It was set as the load value (Li). The maximum value is a maximum value initially identified in the process, and is a maximum value at a point where the required force increases and then decreases first, or a maximum value at a point at which the required force first converges. And, when the time point at which the maximum value is confirmed by the two pressing means is different, the initial load value Li is the maximum value that is first confirmed. [19] In the present application, the elapsed load value (Lf) measured 3 minutes after the base resin and the curing agent are mixed is the capacity of the mixer by injecting the base resin and the curing agent into the mixer by pressing means described below, respectively. Pressing is stopped when it reaches about 95% of (volume), and after 3 minutes of the stop time has elapsed, the resin composition is first discharged through the discharge part of the mixer by pressing again with a mixer at a constant speed of 1 mm/s, The required force was measured, and the maximum value was taken as the aging load value Lf at the point where the force became the maximum value. The maximum value is a maximum value initially identified in the process, and is a maximum value at a point where the required force increases and then decreases first, or a maximum value at a point at which the required force first converges. And, when the time point at which the maximum value is confirmed by the two pressing means is different, the elapsed load value Lf is the maximum value that is first confirmed. [20] After filling the main resin into one of the two cartridges described later, filling the other cartridge with a curing agent, applying a certain force with a pressure means described later, and mixing in a mixer described later via the discharge portion of the cartridge described later, a mixer described later The load value was measured while being discharged to the discharge part of. In the resin composition, the initial load value Li measured immediately after the main resin and the curing agent are mixed may be about 10 kgf or more to about 40 kgf or less. For example, the initial load value Li may be about 10 kgf or more, 12 kgf or more, or about 14 kgf or more, and may be about 40 kgf or less, 38 kgf or less, or about 36 kgf or less. [21] In addition, the elapsed load value Lf measured after 3 minutes elapsed after the base resin and the curing agent are mixed may be about 50 kgf or less, and the lower limit thereof may be, for example, about 20 kgf or more. For example, the aging load value measured after curing for 3 minutes may be about 50 kgf or less or about 48 kgf, and may be about 20 kgf or more, 22 kgf or more, or about 24 kgf or more. [22] The load value as described above is particularly advantageous for the formation of a battery module having a specific structure as described later, and if the load value is too low, overflow may occur after injection or the storage stability of the resin composition may be deteriorated. In addition, a load value that is too high may strain the injection equipment of the resin composition, shortening the life of the equipment or reducing the productivity of the battery module. [23] In one example, the load change rate of the resin composition may have a range of about 1 to about 3 or less. In the present application, the term load change rate is the ratio of the initial load value (Li) measured immediately after the base resin and the curing agent are mixed to the aging load value (Lf) measured after 3 minutes elapsed after the base resin and the curing agent are mixed. That is, it can be defined as Lf/Li. [24] When the load change rate is more than 3, it means that the increase in the load value is large, which means that the curing speed of the resin composition is fast, and thus, overloading of the injection equipment may occur. On the other hand, when the hatching change rate is less than 1, it means that the increase in the load value is not large, the curing speed of the resin composition is slow, and the productivity of the battery module may decrease. [25] Therefore, when the initial load value (Li) of the resin composition satisfies the general formula 1, and the load change rate (Lf/Li) satisfies the range of the general formula 2, the injection process of the resin composition is excellent and the injection equipment Overload can be prevented. [26] In the present application, Li and Lf may be referred to as temporary hardening load values. In the present application, temporary hardening may mean that the antispasmodic state has not been reached, and the antispasmodic state means that the material injected into the module to manufacture the battery module is cured sufficiently to perform a function as an adhesive with a function such as heat dissipation. It can mean a state that can be viewed as being. Haebomyeon described, for example, urethane resin, curing binary state, at room temperature and 30-70% relative humidity, based on a 24-hour hardening, 2250 cm as evidenced by FT-IR analysis -1 NCO peak based on the conversion rate in the vicinity of ( conversion) is 80% or more. [27] In the present application, the mixer may include two cartridges and one mixer combined with the cartridges. 1 is a cross-sectional view showing an exemplary mixer 1 of the present application. The mixer (1) may be composed of two cartridges (2a, 2b) and one mixer (5). [28] The cartridge 2 is not particularly limited, and a known cartridge may be used as long as it can accommodate a base resin and a curing agent. In one embodiment, the diameter of the cartridges 2a, 2b containing the main resin or the curing agent is a circular shape of about 15 mm to about 20 mm, and the diameter of the discharge portions of the first discharge portions 4a, 4b for discharging the main resin or the curing agent is It is a circular shape of about 2mm to about 5mm, the height is about 80mm to 300mm, and the total capacity may be 10ml to 100ml. [29] The cartridge (2a, 2b) may have a pressing means (3a, 3b). The pressing means 3a and 3b are not particularly limited, and known pressing means 3a and 3b may be used. As an example, the pressing means may use a TA (Texture Ananlyer). The pressing means (3a, 3b) may press the cartridges (2a, 2b) to discharge the main resin and the curing agent in the cartridge through the mixer (5). The pressing speed of the pressing means 3a and 3b may be about 0.01 to about 1 mm/s. For example, the pressing speed may be about 0.01 mm/s or more, 0.05 mm/s or more, or about 0.1 mm/s or more, and about 1 mm/s or less, 0.8 mm/s or less, 0.6 mm/s or less, 0.4 mm/s s or less or about 0.2 mm/s or less. Meanwhile, the mixer 5 is not particularly limited as long as it can mix the resin composition discharged by two cartridges, and a known mixer may be used. As an example, the mixer may be a static mixer (5). In one embodiment, the static mixer 5 is mixed by the two receiving portions 6a and 6b respectively receiving the main resin and the curing agent from the two cartridges 2a and 2b, and the static mixer 5 It has one second discharge part 7 for discharging the resin composition, the size of the receiving parts 6a and 6b is a circular shape with a diameter of about 2 mm to about 5 mm, respectively, and the diameter of the second discharge part 7 is 1 mm It is a circular shape of 3mm to 3mm, and the number of elements may be about 5 to about 20. Meanwhile, the capacity of the mixer 5 may have a capacity that satisfies the range of General Formula 3 below. [30] [General Formula 3] [31] V
