Environmental protection, energy-saving and waterproof profile wall material for prefabricated building and production method thereof

Abstract

The invention relates to the field of building wall materials for industrial plants, residential houses, hotels, schools, etc., in particular to an environmentally friendly, energy-saving and waterproof wall material for prefabricated buildings and a production method thereof. 900-1400 parts of lightweight concrete; 1.75-2.1 parts of adhesive; 5.52-6.07 parts of energy-saving materials; 60-90 parts of steel reinforcement materials; 4.2-5.2 parts of wall putty, 5.2-7.0 parts of exterior wall putty, 10.5-14 parts of waterproof latex paint; the light coarse particle material is one or more of waste polystyrene foam, polyurethane foam and waste phenolic resin foam The produced granules have a particle size of 5-15mm and a bulk density of 10kg / m 3 . The invention has the advantages of low water absorption, non-toxic and harmless, heat preservation and energy saving, and high service life.

Description

technical field [0001] The invention relates to the field of building wall materials for industrial plants, residential houses, hotels, schools, etc., in particular to an environmentally friendly, energy-saving and waterproof wall material for prefabricated buildings and a production method thereof. Background technique [0002] The following defects generally exist in existing steel structure buildings and wall materials for reinforced concrete buildings: [0003] 1) The energy saving and environmental protection performance is poor, especially the "cold (hot) bridge" of composite wall materials has not been solved, especially in the north. In winter, indoor frost can be seen due to the cold bridge. When the indoor temperature is slightly higher, frost hangs Condensed water is formed; in the south, due to the thermal bridge, the energy loss during cooling is large, and it has not been solved for many years. [0004] 2) In the existing composite wall materials currently on ...

AI Technical Summary

Problems solved by technology

[0003] 1) The energy saving and environmental protection performance is poor, especially the "cold (hot) bridge" of composite wall materials has not been solved, especially in the north. In winter, indoor frost can be seen due to the cold bridge. When the indoor temperature is slightly higher, frost hangs Condensed water is formed; in the south, due to the thermal bridge, the energy loss during cooling is large, and it has not been solved for many years.

[0004] 2) In the existing composite wall materials currently on the market, due to the difference in density and physical and chemical properties of the two materials between the outer leaf reinforced concrete and the sandwich energy-saving material, there is a small gap between the interfaces. It is precisely because of the interface gap that in Condensation water is generated in winter in the north, followed by freezing and swelling. Repeated freezing and swelling cause damage to the outer leaf concrete, which seriously affects the service life of the building

[0005] 3) In the past two or three years, the composite wall material imported and purchased from abroad is used for composite FRP connectors. This material is a glass fiber reinforced plastic material made of a certain resin, and its aging resistance and durability are poor. Great impact on durability

[0006] 4) Ordinary concrete composite prefabricated wall materials have appeared in various places in my country in the past ten years. The surface density of the board is high. Take the composite wall materials produced by several enterprises in a provincial city as an example. It is difficult and cannot meet the needs of prefabricated steel structure buildings and prefabricated concrete buildings. At the same time, due to high production costs, transportation and installation costs, the market cannot accept it
