Description

Technical field [0001] The invention relates to a fire-resistant, flame-retardant and heat-insulating material capable of resisting high temperature and pressure change and a preparation method thereof. Background technique [0002] In recent years, as the problems of automobile pollution and energy depletion have attracted more and more attention, the state is vigorously promoting the development of new energy industries, especially the new energy automobile industry. As the most important component of new energy vehicles, batteries have always been concerned about their safety and reliability. Safety has always been the biggest threat to new energy vehicles. Partial failure of new energy vehicle batteries will cause the entire group or even the entire set of vehicle batteries to fail due to high temperatures. It is a very interesting thing. So how to improve the safety and reliability of batteries and how to improve new energy vehicles The safety of the new energy industry is ...

Problems solved by technology

[0003] The heat insulation materials commonly available in the market now either have poor heat insulation effect under high temperature conditions, or are easily deformed under high temperature conditions.

The special airgel heat insulation sheet has a good effect on the electric heat insulation of new energy vehicles, but its multiple defects restrict large-scale use: First, airgel products are difficult to bend, have poor toughness and are not suitable for heat insulation of special-shaped products ; Second, the process operation is difficult and it is difficult to achieve mass production of ultra-thin products; third, the airgel heat insulation sheet is expensive

[0004] The above conditions limit its large-scale use in the heat insulation of new energy batteries, and if the battery is left to fail at high temperature, it will greatly increase the risk factor of new energy vehicle drivers and passengers, threatening the safety of life and property
