With rapid economic development, my country has become a major automotive industry. However, the frequency of automobile accidents remains high, with fires being a particularly serious and frequent occurrence.
In the event of a fire, the flammable organic insulation material installed under the vehicle can fuel the fire and generate a large amount of toxic gases, directly harming passengers' respiratory and nervous systems and making escape difficult.
Therefore, the use of inorganic, ultra-efficient, fire-retardant, and flame-retardant gel felt can significantly slow the spread of fire, giving passengers more time to escape. By placing an aerogel fire barrier between the battery compartment and the passenger cabin, the fire can be prevented from spreading in the event of a battery fire, increasing escape time and ensuring the safety of passengers on the upper deck. By replacing the existing organic foam insulation material in the vehicle body, the damage caused by the rapid spread of flames can be reduced. By adding a thermal insulation layer to the exterior of the battery compartment, the damage caused by a fire can be effectively reduced while also ensuring the battery's performance at low temperatures.
● Advantages of using aerogel insulation materials in the automotive and power battery sectors: Aerogel felt offers excellent thermal insulation, effectively reducing the negative impacts of low ambient temperatures on battery charging and discharging efficiency, prolonged charging times, and other issues.
● While achieving the same thermal insulation performance, aerogel felt is thinner, significantly reducing the volume and weight of the battery compartment.
● Aerogel felt offers stable performance, maintaining a relatively stable battery temperature and effectively extending battery life.
● As an inorganic material with Class A fire protection, aerogel felt offers a certain degree of protection against spontaneous combustion of batteries or the spread of combustion from the vehicle compartment to the batteries, ensuring vehicle safety and stability.
● Aerogel felt's porous structure and high porosity also provide sound absorption and impact resistance, ensuring a comfortable interior environment. It is also waterproof and breathable, effectively inhibiting mold growth and improving the interior environment.
● Machinability: It can be shaped arbitrarily and can be fitted into the compartment as a custom-shaped piece.
● It reduces heat transfer between batteries, minimizing the risk of sudden temperature increases during thermal runaway, thus ensuring passenger safety. The material itself is inorganic and non-conductive, which can reduce the risk of leakage to a certain extent.
