Problems solved by technology

However, the texture of all existing thermal insulation materials cannot meet the physical and appearance requirements of the wall surface, and the construction method is cumbersome, which is not only troublesome, but also high in cost and high in quality hazards.
The combination of a variety of materials with different properties will cause a series of problems: fire prevention, waterproof penetration, thermal stress deformation resistance, wind pressure shedding resistance, freeze-thaw cracking resistance, poor environmental protection, etc.

Abstract

The invention discloses a multi-layer foam crystallite heat preservation and decoration composite board and a manufacturing method of the multi-layer foam crystallite heat preservation and decoration composite board. The multi-layer foam crystallite heat preservation and decoration composite board is composed of at least two kinds of a high-density crystallite material layer, a medium-density crystallite material layer, a medium-low-density crystallite material layer and a low-density crystallite material layer in a high-temperature preparation mode. A transition layer is arranged between adjacent crystallite material layers different in density. The multi-layer foam crystallite heat preservation and decoration composite board is low in specific gravity but high in strength and rigidity, has the A1-level fireproof performance, and is excellent in corrosion resistance, heat preservation performance and heat insulation performance.

Description

[0001] Technical field: [0002] The invention relates to the technical field of engineering materials, in particular to a multi-layer foam microcrystalline thermal insulation and decorative composite board and a manufacturing method thereof. [0003] Background technique: [0004] Walls are an important part of buildings. Its main function is load-bearing, enclosure or space separation, divided into load-bearing walls, non-load-bearing walls, and shear walls. Usually in construction, the design requirements for walls include the following points: ① have sufficient bearing capacity and stability, ② have thermal insulation and heat insulation performance, ③ sound insulation performance, ④ meet fire protection requirements, ⑤ moisture-proof and waterproof requirements, ⑥ Construction industrialization requirements. In order to meet these six requirements, there are usually brick-concrete structures, frame structures, reinforced concrete, thermal insulation structures, and decor...
