Abstract

The present invention is molding and combining method of making building board with solid waste. Wood dust and waste plastic are kneaded to form wood-plastic composite, waste plastic and flyash are kneaded to form plastic-flyash composite, and the composite board with one middle wood-plastic composite layer and two surface plastic-flyash composite layers is then produced through molding. The composite board product has compression strength of 22-36 MPa, bending strength of 15-28 MPa, bending modulus of 450-980 MPa, breaking elongation of 80-300 %, oxygen index not lower than 25 and use temperature range of -20 deg.c to +55 deg.c, and is mildew-proof, antiageing, wear resistant, corrosion resistant, hydrophobic and smooth. When used as building formwork, the composite board may be used for over 50 times.

Description

technical field [0001] The invention belongs to a production method for preparing a new type of building plate by a solid waste molding composite method. Background technique [0002] my country is a country with poor forest resources. Every year, a large amount of wood chips, sawdust and wood powder are not used rationally or are discarded; while fly ash and waste plastics are wastes that seriously pollute the environment. Making full use of these solid wastes to develop high value-added products can reduce pollution, turn waste into wealth, and regenerate resources. It is a resource recycling project with obvious economic and environmental benefits. [0003] Chinese patents "01119861" and "02160123" respectively disclose inventions titled "a wood-plastic building template and its production and preparation method" and "a wood-plastic composite material and its preparation method and application". These two patents use: ① only pure PP or modified waste plastic PP. No othe...
