Wall surface energy-saving decorative board and manufacturing method thereof

Abstract

The invention relates to a wall surface energy-saving decorative board and a manufacturing method thereof. The wall surface energy-saving decorative board is manufactured by the following raw materials in portions by weight: 10-20 portions of cement, 50-55 portions of pulverized coal ash, 10-20 portions of water, 2-3 portions of fiber glass mesh, 3-5 portions of high polymer, 0.1-0.5 portion of foaming agent, 0.01-0.1 portion of air entraining agent, 0.01-0.5 portion of foam stabilizer and 6-12 portions of auxiliary materials. The manufacturing method of the wall surface energy-saving decorative board comprises the following steps: mixing, pulping, molding, autoclaving, curing and veneering. The invention has the advantages that the consumption of mineral resources is reduced, and simultaneously solid wastes produced by power industry are consumed; the wall surface energy-saving decorative board has relative low material price, simple manufacturing process, saved cost, heat preservation and insulation, water resistance (low water absorption), lighter weight, no burning or gas release on high-temperature open fire, extremely low heat conductivity factor, high shock resistance and wide serviceable range.

Description

technical field [0001] The invention relates to a wall surface energy-saving decorative board and a manufacturing method thereof. Background technique [0002] Thermal insulation decorative panels are also called thermal insulation and decoration integrated finished panels. Generally, they are named energy-saving decorative panels, composite thermal insulation decorative panels, and external wall thermal insulation panels in the market. They are prefabricated panels in the factory. It is made of composite fabrics, most of which are used on the exterior walls of buildings, and have the functions of heat preservation, energy saving and decoration. [0003] At present, the products on the market are mainly divided into two categories, one is the organic board type, the other is the inorganic board type, and the organic board type is divided into EPS board (molded polystyrene board), XPS (extrusion plastic board) polystyrene board), rigid foamed polyurethane board, etc., the ab...

AI Technical Summary

Problems solved by technology

The XPS board and rigid foamed polyurethane board, in addition to enhanced strength, have greatly improved fire safety compared to EPS boards, still have good dimensional stability under flames and high temperatures, and are non-combustible in air. It burns slowly in oxygen, and can resist strong acid and strong alkali and organic solvents to a certain extent. However, there are still problems in fire safety. Under the erosion of the environment, smoke will still be released. This smoke also contains toxic substances, which will also cause serious harm to personnel if inhaled. However, its environmental protection performance is the same as that of EPS materials. After the product is discarded, it will become pollutants.

[0004] The core board material of the inorganic insulation board type is expanded vitrified bead board and expanded perlite. These products are compared with the above-mentioned EPS board and XPS board in terms of heat insulation, waterproof, light weight, fire safety, and environmental protection. There have been leaps and bounds, but there are still problems: both expanded wave flower pearl powder and expanded perlite are mineralized products, which need to consume a certain amount of mineral resources and need to be processed. From this perspective, it is very difficult to analyze the raw materials. It does not conform to the principle of environmental protection, it is not easy to obtain materials, and the cost is relatively high; it is relatively heavy compared to EPS boards and XPS boards; it is complete in decoration, and the decoration style is relatively single, and there are not many changes, so it is difficult to meet various market demands at the same time. Most are just for outdoor wall decoration
