Preparation method of original-ecology self-heat-insulation and decoration integrated wall material

Abstract

The invention discloses a preparation method of an original-ecology self-heat-insulation and decoration integrated wall material. According to the wall material, waste EPS (expandable polystyrene), ceramsites (clay, shale and fly ash) and loess-MES improved puffed virgin soil serve as aggregates, accessories comprise fly ash, quick lime, aerogel, sticky rice juice, cement, graphite slag, glass strings ( fibers) and the like, the raw materials are stirred, molded and pressed according to the proportion to form the wall material. A building wall is prepared from low-carbon, energy-saving and environment-friendly materials, a heat insulation system and a decoration system are integrated, the integrated wall material can be applied to building walls (inner and outer wall plate or filled wall brick materials), and parts of traditional concrete members are replaced. The wall material improves independent plate property, waterproof permeability, overall tightness, fireproof safety and light performance of a traditional building wall material and is healthy and environmentally friendly.

Description

technical field [0001] The present invention relates to thermal insulation, energy saving and decorative wall materials for building exterior walls, in particular to a material composition mainly using loess for buildings, and in particular to an environmentally friendly wall material and its molding that integrates heat insulation, heat preservation and decoration effects processing technology. Background technique [0002] Present building group all adopts the method for hanging thermal insulation board to its thermal insulation, but the problem that occurs thereupon is more and more. [0003] 1) For the decoration of building facades, people require not only to bring aesthetic feeling visually, but also to securely attach the decorative layer to the main body of the building without hollowing, shedding, water seepage, damp, mildew, flammability, etc. . However, the safety and stability of the insulation board is poor, it is easy to fall off and cause a fire, and the wal...

AI Technical Summary

Problems solved by technology

Moreover, the toxic and harmful substances in these materials will directly endanger people's health and even life safety. In recent years, there have been many serious fires, causing a large number of casualties and property losses. It is urgent to solve the problem of fire prevention of thermal insulation materials.

[0005] 3) The traditional building walls all use cement concrete walls, which release unpleasant odors in the early stages of the building, and can cause various cancers and various skin diseases

[0006] 4) At present, whether it is an assembled self-insulating block or a wall panel, the single block material generally adopts a load-bearing self-insulating masonry material made of an anisotropic frame structure system. This type of block has poor integrity and low strength. It must be assembled by cement mortar. If the mortar is not strong enough and there are gaps, there will be serious safety hazards, and the thermal bridge transfers quickly, and the thermal insulation performance is poor.

[0007] 5) Traditional external wall insulation is all on-site bonding construction. If there are problems with materials and structures during the construction process, the finish layer will crack, which is not convenient for users to redecorate and hang ornaments; it takes up indoor space; During building energy-saving renovation, it will greatly interfere with the daily life of residents; insulation and ring beams, floor slabs, and structural columns will generate thermal bridges, resulting in large heat loss; the wall is greatly affected by the outdoor climate, and the temperature difference between day and night and winter and summer may easily cause Cracked walls and rainwater seepage
