High-strength wood-plastic composite material

[0027] Example: as attached figure 1 , 2 , 3 and attached Figure 4 As shown, a high-strength wood-plastic composite material includes 25-30 parts of high-density polyethylene, 60-70 parts of miscellaneous wood powder, 0.5-1.5 parts of calcium powder, 2-3 parts of maleic anhydride grafted PE, 2- 4 parts of polyethylene wax, and 5-7 parts of nano titanium dioxide crystal colloid.

[0028] In this embodiment, the nano-titanium dioxide crystal colloid is an anti-ultraviolet agent, which improves the sun-resistant durability of the wood-plastic composite material.

[0029] The preparation method of high-strength wood-plastic composite material includes the following steps in sequence:

[0030] S1. The raw materials are heated, stirred and mixed to obtain the material to be granulated;

[0031] S2, granulation;

[0032] S3, extrusion molding;

[0033] S4, high temperature deep embossing;

[0034] S5, surface grinding.

[0035] In the step S1, first add the miscellaneous wood p
