Abstract

The invention discloses an aerogel-containing thermal insulation material. The thermal insulation material comprises an organic foaming material base material, graphene aerogel particles and phase change microcapsules, wherein the graphene aerogel particles and the phase change microcapsules are dispersed in the base material. The preparation method comprises the following steps: polyvinyl chloride pre-swelling, polyvinyl chloride plasticizing, nitrile rubber and polyvinyl chloride melt blending, low-temperature open milling, mold pressing foaming and slicing. The aerogel-containing thermal insulation material provided by the invention has the advantages of low production cost, excellent cold resistance, low density, good bending resistance and softness, no overflow of aerogel dust, washability and functions beneficial to human bodies. The aerogel-containing thermal insulation material is mainly used as a cold-proof thermal insulation material at a low temperature in a natural environment, and is particularly suitable for being applied to the fields of textile and clothing, home textiles, outdoor articles and the like. The application range of aerogel is widened.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an aerogel-containing thermal insulation material and a preparation method thereof, belonging to the technical field of thermal insulation materials. Background technique [0002] In the cold winter, people usually choose clothes made of various cold-proof and warm-keeping materials, for example, warm clothes filled with down or chemical fiber cotton, warm clothes made of animal fur or imitation fur materials, these clothes can basically Meet people's daily warmth needs. Clothes filled with down are relatively lightweight and have acceptable warmth retention, but the warmth retention is greatly reduced in humid environments. At the same time, there are problems such as bloated, easy to run down, difficult to clean, and easy to mildew, which affect the wearing experience and use. life. And adopt the thermal clothing of animal fur or imitation fur, warmth retention property is acc...
