In recent years, due to my country's major layout of new energy vehicles and the orientation of relevant policies, the number of production, supply and sales has continued to grow, and the pace of industrial development has continued to accelerate, which has also promoted the upgrading of the safety factor of new energy vehicle components.
At present, pure electric vehicles mainly use lithium batteries as power batteries. After years of development, the safety factor of lithium-ion battery power batteries has been significantly improved. However, under extreme conditions, lithium batteries still have the risk of ignition and explosion. Lithium battery fire or explosion has become an important technical cause of new energy vehicle accidents. Therefore, it is a top priority to find new materials that are more fire-resistant and flame-retardant for lithium battery sealing maintenance weapons and equipment. At present, common power battery insulation materials include foam, foam plastic, glass wool, high-silica cotton, vacuum insulation board, etc., but in the marketing and promotion of new energy vehicles, there is a trend of multi-pronged approach with advantages and disadvantages .
The main energy source of new energy vehicles is the battery pack, which provides drive electromagnetic energy for the vehicle. In order to protect the electronic components inside the battery pack from being corroded by dust, precipitation, etc., the sealing equipment of the battery pack must also consider flame retardancy, heat resistance, low heat transfer coefficient, no harmful gas, waterproof, shockproof, lightweight and thin Six functions of thickness and price parity. Therefore, the waterproof and sealed design of the battery pack is very important. With its high-quality physical properties, excellent electrical properties and reliable performance, foamed silica gel can effectively solve the problems of sealing and shock absorbing of the left and right covers of the battery pack of new energy vehicles and the support of other car components.
Foamed silica gel is a lighter solid raw material used in engineering projects at this stage. It uses raw silica gel, fillers, vulcanization accelerators, and foamed rubber as raw materials. After the rubber is evenly mixed, polyurethane foamed vulcanized rubber is made at high temperature. A porous structure, low density, compressible polymer material polyurethane elastomer raw material. The insulation layer is environmentally friendly, non-toxic and odorless, and has good flexibility. Long-term use without deformation, shrinkage resistance, corrosion resistance, aging resistance, and UV resistance. Heat resistance (up to -40~220°C). Therefore, it has become an ultra-thin and high-efficiency heat insulation, heat preservation, waterproof and sealing weapon for new energy vehicles and power batteries.
