Embodiment 1

[0019] An outdoor high wear-resistant PVC wood-plastic composite board for construction, which is made by mixing and stirring the following components by weight:

[0020] 80 parts of PVC, 60 parts of rice straw powder, 20 parts of PS, 5 parts of trimethylolpropane triacrylate, 3 parts of sorbitol, 6 parts of phenol, 2 parts of formaldehyde, 4 parts of caustic soda, acrylonitrile-butadiene styrene copolymer 5 parts, 4 parts of calcium stearate, 2 parts of methyl ethyl ketone oxime, 4 parts of molybdenum dithiocarbamate. The preparation method is as follows: weighing the above-mentioned components according to the proportion and performing mixing treatment to obtain a mixed material; then extruding the obtained mixed material with an extruder to obtain a finished product.

Embodiment 2

[0022] An outdoor high wear-resistant PVC wood-plastic composite board for construction, which is made by mixing and stirring the following components by weight:

[0023] 90 parts of PVC, 79 parts of rice straw powder, 25 parts of PS, 8 parts of trimethylolpropane triacrylate, 7 parts of sorbitol, 11 parts of phenol, 5 parts of formaldehyde, 8 parts of caustic soda, acrylonitrile-butadiene styrene copolymer 9 parts, 8 parts of calcium stearate, 5 parts of methyl ethyl ketone oxime, 8 parts of molybdenum dithiocarbamate. The preparation method is as follows: weighing the above-mentioned components according to the proportion and performing mixing treatment to obtain a mixed material; then extruding the obtained mixed material with an extruder to obtain a finished product.

Embodiment 3

[0025] An outdoor high wear-resistant PVC wood-plastic composite board for construction, which is made by mixing and stirring the following components by weight:

[0026] 82 parts of PVC, 64 parts of rice straw powder, 22 parts of PS, 6 parts of trimethylolpropane triacrylate, 4 parts of sorbitol, 7 parts of phenol, 3 parts of formaldehyde, 5 parts of caustic soda, acrylonitrile-butadiene styrene copolymer 6 parts, 5 parts of calcium stearate, 3 parts of methyl ethyl ketone oxime, 5 parts of molybdenum dithiocarbamate. The preparation method is as follows: weighing the above-mentioned components according to the proportion and performing mixing treatment to obtain a mixed material; then extruding the obtained mixed material with an extruder to obtain a finished product.

Abstract

The invention discloses an outdoor high wear resistant PVC plastic-wood composite board for buildings. The composite board is made of the following components by weight: 80-90 parts of PVC, 60-79 parts of rice straw powder, 20-25 parts of PS, 5-8 parts of trimethylolpropane triacrylate, 3-7 parts of sorbitol, 6-11 parts of phenol, 2-5 parts of formaldehyde, 4-8 parts of caustic soda, 5-9 parts of an acrylonitrile-butadiene styrene copolymer, 4-8 parts of calcium stearate, 2-5 parts of methylethylketoxime, and 4-8 parts of molybdenum dithiocarbamate. The outdoor high wear resistant PVC plastic-wood composite board provided by the invention ahs the advantages of high strength, good plasticity, wear resistance, low cost, strong corrosion resistance and the like, is encironment-friendly, and can be widely used in building decoration, door and window frames, furniture manufacturing and other fields.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an outdoor high wear-resistant PVC plastic-wood composite board. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly building material that has only emerged in recent years, and it has just started abroad. The raw materials used in wood-plastic products can be used as base materials such as waste plastics, waste wood, agricultural and forestry straws and other plant fibers, and do not contain any additional harmful ingredients. Moreover, it can be recycled and reused, which can be called a novel product of environmental protection, energy saving, and resource recycling in the true sense. [0003] "Wood-plastic material", also called "wood-plastic composite material", as the name suggests, can be understood as mainly using plastic as raw material, adding wood powder, rice husk, straw and other waste plant ...
