Impact-resistant heat insulation plate and application thereof

Abstract

The invention discloses an impact-resistant heat insulation plate and application thereof. The impact-resistant heat insulation plate comprises a mica plate, high-temperature-resistant ceramic wool covering the mica plate and mica paper wrapping the mica plate and the high-temperature-resistant ceramic wool, wherein the high-temperature-resistant ceramic wool is coated with a fireproof coating layer; the mica plate is made of mica paper, serves as a middle material of the heat insulation plate and has good impact resistance; and the ceramic wool is of a net-shaped structure, belongs to inorganic silicate fibers, is incombustible, wraps the surface of the mica plate and has good flame retardance and heat insulation performance. Due to the formula design of the fireproof coating layer coating the high-temperature-resistant ceramic cotton, the impact-resistant heat insulation plate is further enhanced in heat insulation performance and can resist long-time burning without perforation andpulverization.

Description

technical field [0001] The invention relates to the field of materials, in particular to an impact-resistant heat insulation board and its application. Background technique [0002] The impact-resistant heat insulation board is used to place the cells of the new energy battery pack, between the battery pack and the box, to prevent one cell from being out of control and then affecting the next cell, or one battery pack being out of control and then affecting the next The battery pack plays the role of isolation. At present, mica sheets, airgel, asbestos paper, etc. are often used as materials for heat insulation boards on the market; mica sheets are characterized by high density and high specific gravity, which are hard materials and cannot be used for products with curved or irregular curved surfaces. The thermal performance is good; the characteristic of airgel is that it has a good heat insulation effect, but the thickness is difficult to make thin, and the thinnest is on...
