A kind of environment-friendly and energy-saving paper-faced wall panel and its manufacturing method

Abstract

The invention relates to an environmentally-friendly and energy-saving paper wall board and a manufacturing method thereof. The environmentally-friendly and energy-saving paper wall board is characterized in that a board core is arranged between two composite surface layers composed of coveing papers and non-woven fabrics, the board core is prepared from the following raw materials in parts by weight: 20-50 parts of crop straw, 15-40 parts of light burned magnesium, 3-9 parts of white latex, 10-30 parts of expanded poly styrol powder and 11-33 parts of water, and the thickness of the board core is 60-300mm. Compared with the prior art, the invention has the beneficial effects that: 1) primary compression moulding is adopted, no heating or drying is required; 2) the product has the advantages of environmental friendliness, energy conservation, light weight, high compression strength, low cost and the like; 3) the crop straw and the expanded poly styrol powder are all abandoned resources, thus the effects of environmental protection and energy conservation are achieved; and 4) the environmentally-friendly and energy-saving paper wall board provided by the invention is applicable to multiple civil buildings and can be well matched and connected with various frame structures, steel structures and heterotype structures.

Problems solved by technology

[0002] At present, wall panels are widely used in the assembly and decoration of various building interior walls, exterior walls, and ceilings. Diatomite, fly ash, etc.) and various stabilizers, reinforcing agents, modifiers, accelerators, foaming agents, etc., because some of the raw materials contain chemical substances such as formaldehyde, which have certain effects on human health Harm; some contain wood, which will not only waste wood resources, but also cause damage to the ecological environment, and the cost is relatively high; some contain cement and other raw materials, which are more complicated in terms of production process and raw material composition ratio; The high-quality wall panels have certain defects in the selection of raw materials, the ratio of raw materials, and the process of the process. They have certain defects in environmental protection, energy saving, waterproof, fire prevention, light weight, heat preservation, sound insulation, heat insulation, strength, and service life. In terms of cost, the combination cannot meet people's needs for building wall materials and decorative materials
