Embodiment Construction

[0013] The present invention is described in further detail below in conjunction with specific embodiments;

[0014] An injection molding material, consisting of the following components by weight:

[0015] Wood pellet material 40~80;

[0016] Nano calcium carbonate 10~20;

[0017] Stearic acid 20~50;

[0018] Impact resistance agent 10~20;

[0019] Toughening agent 1~5;

[0020] Industrial paraffin 10~20;

[0021] Titanium dioxide 5 to 10.

[0022] The wood particle material is obtained by crushing one or two or more wood wastes as raw materials, and the wood wastes include leaves, wood chips, wood scraps and trees.

Abstract

The present invention discloses an injection material, including by weight: 40-80 parts of a wood granular material; 10-20 parts of nano-calcium carbonate; 20-50 parts of stearic acid; 10-20 parts of an impact modifier; 15 parts of a flexibilizer; 10-20 parts of industrial paraffin; and 5-10 parts of titanium dioxide. According to the present invention, the novel wood plastic material which is recyclable, environmental-friendly and without any harm to human body is used for replacing the conventional molding material taking plastic as the main material; the raw materials are cheap and available (such as trees, leaves, wood chips, and leftover bits and pieces of industrial sheets); the use of plastic can be significantly reduced; simplicity of the injection material is changed; and the products are high in stability, and have no shrinkage distortion.

Description

technical field [0001] The present invention relates to an injection molding material. Background technique [0002] At present, many injection molding products on the market are mainly made of injection molding materials such as styrene, polycarbonate and polystyrene. On the one hand, these materials contain many harmful chemical components, which will cause harm to human health. Recycling, and it is difficult to degrade after being discarded, which will cause serious environmental pollution. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a wood injection molding which has the characteristics of environmental protection, no harm to the human body, recyclable regeneration, etc., and low cost, thereby overcoming the deficiencies in the prior art. Material. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted in the presen...
