Embodiment Construction

[0030] The present invention makes the formula of wood-plastic composite profile, and makes wood-plastic composite profile through the following steps:

[0031] In the first step, the wood fiber powder is used as the main material to dry the wood fiber powder; the wood fiber powder can be crop straw powder, sawdust left over from timber factory production, bamboo shoots, pine leaves, wooden shells, peanut shells, Rice straw, pine nut shell powder, etc., the particle size of wood fiber powder is 80-100 mesh;

[0032] The second step is to add ingredients to the main ingredients;

[0033] The proportioning (percentage by weight) of main ingredient and batching is:

[0034] Wood fiber powder 33.23%, PVC (polyvinyl chloride resin) 36.93%, filler (can be calcium carbonate) 18.46%, CPE (chlorinated polyethylene) 1.48%, ACR (acrylate copolymer) 1.11%, lubricant ( It can be PE wax or paraffin) 0.45%, stabilizer (can be rare earth stabilizer) 2.95%, plasticizer (can be PVC processing...

Abstract

The invention discloses a formula for manufacturing a wood-plastic composite section. The formula comprises the following materials in percentage by weight: 33.23 percent of wood fiber powder, 36.93 percent of polyvinyl chloride resin, 18.46 percent of filler, 1.48 percent of chlorinated polyethylene, 1.11 percent of acrylate copolymer, 0.45 percent of lubricant, 2.95 percent of stabilizer, 3.18 percent of plasticizer, 0.96 percent of foaming agent and 1.25 percent of toughening agent. The wood-plastic composite section manufactured by the invention has the characteristics of raw material recycling, product plasticizing, environmentally-friendly application, economic cost and renewable recovery.

Description

technical field [0001] The invention relates to a formula for making profiles, in particular to a formula for making wood-plastic composite profiles. Background technique [0002] Wood-polymer Composites (WPC for short) is a new type of material made of wood fiber or plant fiber as the main component, which is combined with thermoplastic resin or other materials after pretreatment. This material can give full play to the advantages of each component in the material and overcome the shortcomings of a single material. It can not only improve the physical and mechanical properties and processing properties of the material, reduce costs and expand the application range, but also increase the added value of the material. Since the product is in a multiphase state of crystalline (wood fiber or plant fiber) and disordered state (resin), it has both the high strength and high elasticity of wood fiber or plant fiber, and the high toughness of the polymer matrix, and High impact stre...
