Description

Technical Field

[0002] Building insulation is an important aspect of saving energy, improving living environment and usage functions. The core of building energy conservation is to innovate the building envelope and heating system. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, and most of it is energy consumption for heating and air conditioning, so building energy conservation is of great significance.

[0003] Nowadays, thermal insulation materials are developing towards the direction of high efficiency, energy saving, thin layer, heat insulation, and waterproof outer protection integration. Aerogel felt, as a new type of thermal insulation material, has received great attention in the field of building insulation, but due to its low mechanical strength and high brittleness, its application in engineering is subject to many restrictions. The thermal insulation board prepared with it has problems such as low strength, inability to withstand high pressure, low material toughness, easy cracking, and high brittleness under small loads. During use, silica aerogel will have particles and dust falling off, which greatly reduces the performance and service life of the board.

[0004] If we want to improve the energy-saving rate of buildings, we must increase the production and use of new thermal insulation materials.

[0005] Based on the above problems, we propose a preparation method and application of a new organic-inorganic composite thermal insulation material. Summary of the invention
