Stone-like foamed cement thermal insulation and decoration integrated board and manufacturing method thereof

Abstract

The invention discloses an imitating stone type foaming cement heat-preservation and decoration integrated board and a manufacturing method thereof. The imitating stone type foaming cement heat-preservation and decoration integrated board comprises a foaming cement composite board, wherein a calcium silicate board anti-cracking layer is embedded into the middle part of the foaming cement composite board; grooves are formed in four side surfaces of a calcium silicate board; holes are formed in the other two surfaces, and the two surfaces are coated with glass fiber alkali-resisting gridding cloth; facing layers are arranged on two sides of the foaming cement composite board; the facing layers and the calcium silicate board anti-cracking layer are parallel to each other on the section of a heat-preservation and decoration board. By embedding the calcium silicate board into foaming cement layers, compared with a common cement heat-preservation board, the cement foaming heat-preservation and decoration integrated board has the advantages that the mechanical performance is obviously improved, the field construction operation is improved, the problems that foaming cement is easy to crack are solved, decoration layers are directly and continuously processed in a factory, the manufacturing process of the decoration layers is facilitated, the quality can be controlled favorably, the comprehensive quality of a finished product is improved, and the comprehensive cost of the product is reduced.

Description

technical field [0001] The invention relates to a thermal insulation decorative board for building exterior walls, and belongs to the technical field of design and building materials. [0002] Specifically, the present invention relates to a stone-like foamed cement thermal insulation and decoration integrated board and a manufacturing method thereof. Background technique [0003] my country pays more attention to the wall insulation and fire protection requirements of building exterior walls. Inorganic insulation materials can meet the requirements, but the promotion and application of inorganic insulation materials in the market is not ideal. At present, the inorganic external wall thermal insulation materials in the domestic market mainly include rock wool, thermal insulation mortar, foamed cement board, etc. Due to its low strength, rock wool absorbs and expands, which affects product quality; thermal insulation mortar has high requirements for on-site construction, and...

AI Technical Summary

Problems solved by technology

Due to its low strength, rock wool absorbs and expands, which affects product quality; thermal insulation mortar has high requirements for on-site construction, and has been listed as a restricted material in many provinces; The reasons are as follows: ①The foamed cement board material itself is relatively brittle, and its tensile properties are poor, and it is prone to brittle damage during transportation, processing, and construction. Differences in shrinkage properties of foam cement boards lead to cracks

[0004] The exterior wall of the building is decorated with decorative marble and granite. The decoration effect is high-grade and beautiful, but there are many deficiencies in marble decoration, as follows: ① The cost of stone raw materials and stone processing is high; There are strict regulations on quality, and the quality of the exterior wall decorative panels should not be too heavy. ③The thermal insulation and fire resistance of the stone itself is not ideal, and it is difficult to achieve the effect of thermal insulation. It is easy to crack and fall in case of fire

[0005] To sum up, the inorganic thermal insulation effect of the external wall is not ideal at present, and there are many deficiencies in the existing known technology and the current inorganic thermal insulation; although the decorative effect of marble and granite on the external wall is high-grade, there are also many defects and disadvantages
