Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a light, environment-friendly, stable, weather-resistant and flame-resistant thermal insulation material and a preparation method thereof. Background technique [0002] At present, the insulation materials used in the market are mainly divided into two categories: inorganic insulation materials and organic insulation materials. Comprehensive [0003] In general, organic thermal insulation materials have the advantages of light weight, good thermal insulation performance, and good material processability, but they have poor fire resistance, poor stability, and are not resistant to aging. Inorganic thermal insulation materials such as perlite, diatomaceous earth, asbestos, slag wool, foam glass, etc., have certain fireproof properties, but they have high thermal conductivity, poor thermal insulation performance, and large bulk density. However, although the e...
