Composite heat-insulation flexible facing sheet for building wall as well as processing technology and application of composite heat-insulation flexible facing sheet

Abstract

The invention relates to the technical field of building wall decoration, and particularly discloses a composite heat-insulation flexible facing sheet for a building wall and a processing technology and an application of the composite heat-insulation flexible facing sheet for the building wall. The composite heat-insulation flexible facing sheet comprises a soft porcelain facing layer and a heat-insulation bottom layer, and a toughening layer is arranged in the soft porcelain facing layer; the soft porcelain facing layer is prepared from the following raw materials: water, a dispersing agent, a defoaming agent, cellulose ether, an emulsion, blast furnace mineral powder, tailing slag, wollastonite powder, quartz sand, fibers, a thickening agent and pigment; the heat-insulation bottom layer is prepared from the following raw materials: water, cellulose ether, a wetting agent, a dispersing agent, a defoaming agent, a pH regulator, a cosolvent, a sterilizing agent, an emulsion, a water repellent agent, silicon dioxide aerogel, hollow glass beads and a thickening agent. According to the composite heat-insulation flexible facing sheet, through the synergistic effect of the glass fiber grid cloth, the soft porcelain facing layer and the heat-insulation bottom layer, the composite heat-insulation flexible facing sheet not only has good heat insulation and heat preservation performance, but also has the advantages of being light in self weight, good in flame retardance, good in flexibility, good in durability and easy and convenient to construct.

Description

Technical field [0001] This application relates to the field of building wall decoration technology, and more particularly, it involves a composite insulation flexible finish sheet for building walls and its processing processes and applications. Background technique [0002] With the improvement of people's living standards, architectural decoration materials have also been developed. Traditional architectural decorative materials generally use stone or tiles, stone and tiles are self-contained, and need dry hanging, there is a risk of falling off, and the flexibility of stone and tiles is poor, and the adaptability of the base surface is poor, but insulation Poor insulation. There are also some architectural decorative materials with a polybenaded mesenchymal heat preservation system, although the polybenades have better heat insulation insulation, but fire resistance is poor. There is also a partial building decorative material using a flexible finish, and the flexible finish ...

AI Technical Summary

Problems solved by technology

The flexible veneer layer not only has the advantages of good flexibility, good flame retardancy, light weight and good durability, but also the flexible veneer surface layer adopts the method of on-site pasting, which has the advantages of simple and stable construction. When the material is used for the exterior or interior walls of buildings, it can also have the appearance and texture of stone and ceramic tiles, and can also imitate leather, imitate wood, etc., with rich expressiveness, and will become a popular architectural decoration material in the market , although the flexible facing sheet has the above advantages, it still has deficiencies in thermal insulation performance
