Multipurpose heat insulation protective material and production process thereof

Abstract

The invention relates to a multipurpose heat-insulation protective material and a process method thereof, the multipurpose heat-insulation protective material is prepared from the following raw materials by mass: 40%-50% of a binder, 20%-30% of a foaming agent, 25%-35% of a flame retardant and 0.5%-1.5% of a cross-linking agent, the multipurpose heat-insulation protective material has high expansion, flame retardance and flame impact resistance, and when the multipurpose heat-insulation protective material encounters high temperature during use, the multipurpose heat-insulation protective material has good heat insulation performance. The thermal insulation protection material automatically expands in a high-temperature environment in a thermal runaway reaction process, the thickness can be increased by 10-30 times, temperature conduction is effectively isolated by increasing the thickness and the structure of the thermal insulation protection material, and the thermal insulation protection material has the characteristics of strong adhesive force and high viscosity, can be well adhered with various other materials such as metal and plastic, is convenient to install and has a good application prospect. The adhesive has excellent flexibility, can be used for filling uneven and irregular spaces, and is flexible to use and wide in application range.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a multipurpose thermal insulation protection material and a production process thereof. Background technique [0002] The safety of electronic products is an issue that both manufacturers and users are very concerned about. A series of safety accidents caused by thermal runaway of some electronic products are increasing day by day. The existing solution to reduce thermal runaway is to install thermal insulation protection materials in the battery. This traditional thermal insulation protection material is realized by using aerogels, but the drawback of aerogels is that the thermal insulation performance is average and occupies the thickness space. Large, relatively heavy weight, failure in high temperature environment, low flame impact resistance, high processing cost, and lack of practical functionality. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned def...

Problems solved by technology

The existing solution to reduce thermal runaway is to install thermal insulation protection materials in the battery. This traditional thermal insulation protection material is realized by using aerogel, but the disadvantage of aerogel is that the thermal insulation performance is average, accounting for the thickness of the space. Large, relatively heavy weight, failure in high temperature environment, low flame impact resistance, high processing cost, and insufficient practical functionality
