Description

technical field [0001] The invention relates to the technical field of heat insulation and flame retardant, in particular to a pollution-free HS airgel heat insulation, heat insulation, waterproof and flame retardant material and a preparation method thereof. Background technique [0002] Environmental safety is the most challenging and urgent problem facing mankind today. Especially the heat insulation and flame retardant technology and materials in the construction industry must be rethought from the perspective of fire safety and environmental protection. The development of light-weight, thin-layer, safe and environmentally friendly heat-insulating, flame-retardant and heat-insulating materials and simple and efficient construction techniques is the direction of overall technological development in the field of heat-insulation and heat-preservation industry. sign. We must take environmental safety as the starting point. Research on the upgrading and transformation of tra...

Problems solved by technology

It does not fundamentally solve the conduction factors that control the temperature in the environment. For example: comprehensive integration technology that controls the conduction, radiation and convection of temperature

[0005] 2. High resource consumption

Therefore, according to my country's building thermal climate regions and building energy-saving standards, the use of various traditional thermal insulation materials is large (such as: 100 mm in Beijing, 120 mm in Shenyang, 150-180 mm in the north of Harbin), and resource consumption Big

[0007] 3. Material performance is backward

[0008] The performance of traditional insulation board materials is not perfect, and product quality defects obviously affect the quality of the project, such as: poor water resistance, failure in contact with water; poor connection with the base material, easy to fall off; poor construction, complicated procedures, high construction costs, etc.

[0009] 4. The process is complicated and the construction cost is high

[0010] Because the traditional thermal insulation material is mechanically connected to the building wall to form a chemical bond, it cannot be integrated with the building structure. Therefore, many auxiliary materials are used, the process is complicated, the construction period is long, the comprehensive cost of construction is high, and there are quality and safety issues. Hidden danger
