Description

Wall surface energy-saving decorative board and manufacturing method thereof

technical field

The invention relates to a wall surface energy-saving decorative board and a manufacturing method thereof.

Background technique

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.

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 above organic board types have good thermal insulation and decoration, light weight, and good water resistance, but these board types are in fire safety and environmental protection. Sexually, there are great security drawbacks. The main component of the EPS board is the product of polystyrene resin and polymer after heating and catalysis, which is what we generally call "foam". This material will burn or melt when it encounters fire or heat. A large amount of toxic gas (thick smoke) will be generated at the same time. When people inhale it, they will feel uncomfortable in a short time, and more seriously, it will cause coma, which will cause serious and fatal injuries to personnel. Facts have proved that the harmful gas in the fire scene (Dense smoke) is one of the main killers of fires. This characteristic determines that this product can only be used reluctantly on exterior wall decoration, and must not be used on interior decoration. "Foam" is also a well-known typical white pollutant with extremely poor degradation performance. When these products are used on a large scale, large-scale pollution of the environment follows. Materials need to be replaced. 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, but 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. .

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.
