High-intensity wood plastic composite board and fabrication method thereof

Abstract

The invention relates to a wood plastic composite, in particular to a high-intensity wood plastic composite board and a fabrication method thereof. The method for fabricating the high-intensity wood plastic composite board comprises the following steps: treating nano titanium dioxide with silane coupling agent to obtain modified nano titanium dioxide; mechanically stirring the modified nano titanium dioxide, plastic particles, maleic anhydride grafted plastic particles, calcium stearate and the like, and extruding and pelleting all the materials to obtain modified plastic particles; mechanically stirring the modified plastic particles, wood flour, terpene resin, chopped glass fiber, white oil, antioxidant and the like, and extruding, melt-blending and pelleting all the materials to obtain high-intensity wood plastic composite particles; and finally extruding the high-intensity wood plastic composite particles with a machine to mold the high-intensity wood plastic composite board. The high-intensity wood plastic composite board has extremely wide application range, and is applied to the fields such as transportation, construction, decoration, ornament, municipal works, garden and park, packaging and the like. The high-intensity wood plastic composite board has the advantages of reproducibility, low cost and higher mechanical properties such as static bending strength and the like, thereby being an ideal material for replacing wood. Compared with traditional wood plastic composites, the high-intensity wood plastic composite board has longer service life, and is a novel upgrade product of the present wood plastic composites.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a high-strength wood-plastic composite material board and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, wood-plastic composite materials with a wide range of raw materials, environmental friendliness, renewable and recyclable use have attracted more and more attention. Wood-plastic composite materials can be used as packaging materials such as pallets and packing boxes, storage materials such as planks and beams, decoration and decoration materials such as houses, floors, and building templates, and outdoor tables, chairs, benches, etc. used in parks, stadiums, streets, etc. Leisure materials, automotive interior decoration materials, pipes, etc. Wood-plastic composite material has homogeneous material, more stable size than wood, less prone to cracks, and no wood knots, twi...

Problems solved by technology

But there are also some obvious deficiencies, such as low static bending strength, poor bearing capacity, and bending may occur after long-term use. Especially when it is suspended in the air, bending deformation is more likely to occur, which affects its use effect and shortens its service life. , limiting its scope of use
