Abstract

The invention belongs to the technical field of adhesion agents, in particular to a two-component adhesion agent, as well as a preparation method and application thereof. The two-component adhesion agent comprises a component A and a component B with the weight ratio being 2 to 10:1, wherein the component A comprises 100 parts of hydroxyl resin, 3 to 40 parts of silicone resin, 100 to 500 parts of heat conducting materials, 1 to 20 parts of a dehydrator, 10 to 200 parts of a flame retardant, 0.1 to 10 parts of a thixotropic agent, 0.01 to 10 parts of a catalytic agent, and 0.1 to 10 parts of an addition agent; the component B comprises 100 parts of resin containing cyanic acid functional groups, and 1 to 10 parts of a dehydrating agent. The two-component adhesion agent has lower curing shrinkage stress, high adhesive force to battery cells and battery cell protection films, can rapidly release heat generated by charging and discharging of a battery, and improves the efficiency and prolongs the service life of the battery.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a two-component adhesive and its preparation method and application. Background technique [0002] Compared with traditional lead-acid batteries, lithium-ion battery electric vehicles are more efficient, safe and environmentally friendly. Most importantly, lithium-ion batteries are light and durable, making electric vehicles less bulky and more beautiful, so they are more and more popular. At present, the battery of lithium battery electric vehicles is composed of many small batteries, which are fixed by mechanical methods. The car has a lot of impact during operation, and mechanical fixation will cause the cells to rub against each other and affect the service life; when the car collides violently, the impact force between the cells may be too large and the battery will be discharged rapidly And an accident occurs, such as an explosion and a fire.
