[0002] With the rapid development of industry and economic development, the world's demand for energy is also increasing. Among the increasing total energy consumption, building energy consumption is particularly large, accounting for about 11-25% of the total energy consumption. %, a large number of data and experiments have shown that the fastest and most effective way is to use thermal insulation and energy-saving materials, but the supply of metal thermal insulation materials is very small and the price is very expensive. As a building thermal insulation material, the cost will be greatly increased. not widely applicable

[0003] Organic thermal insulation materials are easy to burn, easy to produce toxic gases at high temperatures, and have poor aging resistance and fire resistance. These shortcomings have limited the wide use of organic thermal insulation materials. It is easy to produce dense smoke, and the strength of the insulation material is not good, so it is easy to crack and the manufacture is complicated. Therefore, we propose a kind of anti-fracture energy-saving wall insulation material with flame retardancy and smoke suppression to solve the above problems
