A kind of environment-friendly and energy-saving external hanging wall panel and its production method

Abstract

The invention relates to the technical field of wall materials for buildings such as industrial plants, residential houses, hotels, schools, etc., in particular to an environmental-friendly and energy-saving external wall panel and a production method thereof. The raw material composition and mass parts of the wallboard are as follows: 900-1200 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; 2.2-3.3 parts of composite connectors; decoration materials: 4.2-5.2 parts of interior wall putty, 5.2-7.0 parts of exterior wall putty, 10.5-14 parts of waterproof latex paint. The invention utilizes industrial, agricultural and domestic wastes to produce lightweight concrete, and adopts the environmental protection and energy saving external wall panels produced by the invention, which can meet the needs of production and use of environmental protection and energy saving in different regions such as the north and the south. The invention has the advantages of non-toxic and harmless, flame retardant, heat preservation and energy saving, antifreeze, sound insulation, environmental protection, good durability and long service life (>70 years), and the product has the advantages of waste utilization and environmental protection in the production process.

Description

technical field [0001] The invention relates to the field of wall materials for buildings such as industrial plants, residential houses, hotels, schools, etc., in particular to an environmental-friendly and energy-saving external wall panel and a production method thereof. Background technique [0002] The global energy crisis is intensifying day by day, making energy conservation and efficient use of energy more important. At present, the energy consumed by buildings in my country has accounted for nearly 30% of the total social energy consumption, and it is still growing at a rate of more than 1% per year. If it is not controlled, it may account for 40% of the total energy consumption by 2020. . [0003] Existing exterior wall panels for steel structure buildings and reinforced concrete buildings have poor energy-saving and environmental protection performance, especially the "cold (hot) bridge" of composite exterior wall panels cannot be solved, especially in the north. ...

AI Technical Summary

Problems solved by technology

[0003] Existing exterior wall panels for steel structure buildings and reinforced concrete buildings have poor energy-saving and environmental protection performance, especially the "cold (hot) bridge" of composite exterior wall panels cannot be solved, especially in the north. The reason is that frost hangs indoors, and when the indoor temperature is slightly high, condensed water forms at the place where the frost hangs; a large enterprise in a northern city built a talent apartment with a height of more than 140 meters. Frost or condensation defects

However, in the south of my country, due to the thermal bridge, the energy loss during refrigeration is large, and it has not been solved for many years.
