Embodiment

[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 woo...

Abstract

The invention belongs to the technical field of wood-plastic composite materials, and particularly relates to a high-strength wood-plastic composite material, which comprises 25-30 parts of high-density polyethylene, 60-70 parts of miscellaneous wood powder, 0.5-1.5 parts of calcium powder, and 2-3 parts of Maleic anhydride grafted PE, 2-4 parts of polyethylene wax, and 5-7 parts of nano titanium dioxide crystal colloid. The invention has the advantages of reasonable and effective preparation method, convenient and quick mixing and stirring operation, clear and durable deep embossing, and high overall structural strength of the material.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, in particular to a high-strength wood-plastic composite material. Background technique [0002] Wood-plastic composite material refers to a new type of material prepared by compounding thermoplastics and wood fibers, and is generally used for outdoor decoration. On the other hand, most of the wood-plastic composite materials currently on the market have the problem of poor structural strength, which cannot meet the high-strength use conditions. [0003] The patent publication number is CN105086268A, and the Chinese invention patent with the publication date of 2015.11.25 discloses a high-strength wood-plastic material, which is prepared from the following raw materials in parts by weight: straw powder 30-40, butyl acrylate 10-20, over Benzoyl oxide 0.02-0.03, N,N-dimethylaniline 0.01-0.02, polyethylene wax 3-4, thiodipropionate dilaurate 1-1.2, calcium stearate 1.5-2, po...
