[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

Embodiment 1
[0047] Mix 30 parts of base material, 15 parts of reinforcing material, 5 parts of lubricant, 20 parts of heat-insulating filler, 15 parts of flame retardant, and 10 parts of magnesium hydroxide. After banburying, they are evenly mixed into rubber, and then add 1.5 on the mixer. Parts of the vulcanizing agent 2,5-dimethyl-2,5-2 di-tert-butylperoxide hexane, are smelted uniformly, and the fire-resistant, flame-retardant and heat-insulating material with high temperature and compression resistance is obtained.
Embodiment 2
[0049] Combine 32 parts of base material, 20 parts of reinforcing material, 5 parts of lubricant, 0.5 parts of coupling agent A151, 15 parts of heat insulation filler, 10 parts of flame retardant, 15 parts of aluminum hydroxide, 15 parts of aluminum silicate, 10 parts of cerium oxide After banburying, add 1.2 parts of the vulcanizing agent 2,4-dichlorobenzoyl peroxide to the mixing machine, and the vulcanizing agent will be uniformly produced to obtain the high temperature and compression resistance fire-retardant heat insulation material.
Embodiment 3
[0051] Combine 30 parts of base material, 35 parts of reinforcing material, 2 parts of silane coupling agent, 20 parts of flame retardant, 10 parts of aluminum hydroxide, 15 parts of magnesium hydroxide, and 5 parts of heat insulation filler, and then obtain high temperature through banburying and granulation. Fire-resistant and flame-retardant thermal insulation material resistant to compression changes.

Abstract
The invention discloses a high temperature resistant and pressure change resistant fireproof flame retardant thermal insulation material and a preparation method and application of the high temperature resistant and pressure change resistant fireproof flame retardant thermal insulation material. The high temperature resistant and pressure change resistant fireproof flame retardant thermal insulation material comprises the following components in parts by weight: 20-45 parts of a matrix material, 15-40 parts of a reinforcing material, 10-30 parts of thermal insulation filler, 5-25 parts of a flame retardant, 2-10 parts of a lubricant, 1-5 parts of a coupling agent, 0-2 parts of a vulcanizing agent and 0-5 parts of other additives. The invention further provides a thermal insulation plate and a battery pack, wherein the thermal insulation plate is made of the high temperature resistant and pressure change resistant fireproof flame retardant thermal insulation material. The battery pack comprises a plurality of batteries arranged together, and the adjacent batteries of the battery pack are separated by the thermal insulation plate. The high temperature resistant and pressure change resistant fireproof flame retardant thermal insulation material has the excellent properties of pressure change resistance at the high temperature, thermal insulation at the high temperature, flame retardancy, rapidly porcelain preparation and the like.
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 ...
