Ecological environment-friendly foaming lightweight wallboard and preparation method thereof

Abstract

The invention provides an ecological environment-friendly foaming lightweight wallboard. The ecological environment-friendly foaming lightweight wallboard comprises a foaming matrix and a sealing layer outside the foaming matrix, and the raw materials comprise wood powder, polyethylene particles, an environment-friendly coating and other additives. The invention also provides a preparation method of the ecological environment-friendly foaming lightweight wallboard. The preparation method of the ecological environment-friendly foaming lightweight wallboard comprises the following steps: 1, pretreating the wood powder, the polyethylene particles and glass fiber; 2, mixing the glass fiber and the polyethylene particles to obtain glass fiber modified polyethylene; 3, adding the additives into the glass fiber modified polyethylene and stirring uniformly to obtain a molten mixture, dividing and dispersing the molten mixture into a powder material groove in a pelletizer material distributing device to adhere to the wood powder, and cooling and performing consolidation forming; 4, performing melt extrusion on the mixed materials and then performing forming, layer sealing and cutting processes to obtain the ecological environment-friendly foaming lightweight wallboard. The foaming wall body has the advantages of corrosion resistance, insect prevention, dampproof property, flame retardance and the like, has stripy wood texture, and has relatively good market promotion value.

Description

technical field [0001] The invention relates to a lightweight wallboard and a preparation method thereof, in particular to an eco-friendly foamed lightweight wallboard and a preparation method thereof. Background technique [0002] Lightweight wall panels refer to prefabricated slats made of light materials or light structures, with mortise and tenon grooves and joint grooves on both sides, and surface density not greater than the standard value for non-load-bearing internal partition walls of industrial and civil buildings. . At present, the common lightweight wall panels can be divided into hollow slats, solid slats and composite slats, etc. The hollow slats use cement as the bonding material, industrial slag, fly ash, volcanic ash, polypropylene fiber, foamed perlite, etc. In order to add materials, chemical additives are added and stirred evenly, and the mold is cast to form the product, and the length is cut according to the needs of the project, and then used in build...

Problems solved by technology

At present, the common lightweight wall panels can be divided into hollow slats, solid slats and composite slats, etc. The hollow slats use cement as the bonding material, industrial slag, fly ash, volcanic ash, polypropylene fiber, foamed perlite, etc. In order to add materials, chemical additives are added and stirred evenly, and the mold is cast to form the product, and the length is cut according to the needs of the project, and then used in buildings; the solid slats use cement as the bonding material, industrial slag, fly ash, Mesh cloth, foamed polystyrene particles, etc. are added materials, and chemical additives are added to mix evenly, and the product is cast into a mold to form a product, and the length is cut according to the project's needs, and then used in buildings; composite strips are also called clips The core composite board is made of cement as the bonding material, industrial slag, fly ash, construction waste, lightweight aggregate, etc. The common light-weight wall panels have their own advantages and disadvantages; hollow slats and solid slat-type light-weight wall panels need to be connected with grid cloth and secondary plastering, the construction process is cumbersome, the cost is high, and there are also extended construction periods The size and height of the composite slats, also known as sandwich composite panels, are usually limited by the panel. On the other hand, the composite slats usually use cement as the bonding material and then add foaming materials. The appearance color is single and light. The surface of the wall lacks further protection and the surface is not smooth enough
