Abstract

The invention relates to a high-strength plastic wood dalle and a preparation method thereof. The preparation method comprises the following steps of: modifying nano calcium carbonate by a coupling agent; then carrying out treatment by ultrasonic waves to obtain nano modified wood powder; obtaining modified plastic particles by plastic particles, maleic anhydride grafted plastic particles, wollastonite fibers, calcium stearate and chlorinated polyethylene; obtaining high-strength plastic wood particles by the modified plastic particles, the nano modified wood powder, soybean oil, maleic anhydride grafted polyethylene wax, bi(2,2,6,6-tetramethyl-4-piperidyl) sebacate, tris(2,4-di-t-butylphenyl)phosphite and pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate); and finally forming the high-strength plastic wood dalle. The high-strength plastic wood dalle is convenient to produce, has low cost, has low plastic content, is environmental-friendly, has high bending strength and modulus and high ridigity and has creep resistance and aging resistance. The color of the high-strength plastic wood dalle cannot be changed after the high-strength plastic wood dalle is usedfor a long time. Few mechanical properties are reduced. The service life of the high-strength plastic wood dalle is long. The high-strength plastic wood dalle can be widely applied to various fields of traffic, decoration, municipal garden, packaging and the like.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to a high-strength plastic-wood decorative 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, environmentally friendly, renewable and recyclable materials have attracted more and more attention.
