Embodiment 1

[0014] A plastic-wood composite board, which is composed of the following raw materials in parts by weight: 80 parts of polyvinyl chloride resin, 42 parts of wood powder, 15 parts of silicon flame retardant, 7 parts of plasticizer, 4 parts of foaming agent, glass fiber 12 parts, 3 parts of lubricant, 4 parts of stabilizer.

[0015] In this example, the plasticizer is chlorinated polyethylene.

[0016] In this example, the blowing agent is methyl methacrylate.

[0017] In this example, the stabilizer is a mixture of heat stabilizer, antioxidant and ultraviolet absorber.

[0018] In addition, the lubricant is a mixture of stearic acid, silicone oil and liquid paraffin.

Embodiment 2

[0020] A plastic-wood composite board, which is composed of the following raw materials in parts by weight: 65 parts of polyvinyl chloride resin, 30 parts of wood powder, 8 parts of silicon flame retardant, 5 parts of plasticizer, 2 parts of foaming agent, glass fiber 8 parts, 1 part lubricant, 2 parts stabilizer.

[0021] In this example, the plasticizer is chlorinated polyethylene.

[0022] In this example, the blowing agent is methyl methacrylate.

[0023] In this example, the stabilizer is a mixture of heat stabilizer and antioxidant.

[0024] In addition, the lubricant is a mixture of stearic acid and silicone oil.

[0025] Based on the above, compared with the traditional wood-plastic composite board, flame retardant, glass fiber and other raw materials are added to make the product fully achieve its use function. The product is more tough, rigid and elastic, and the impact resistance and tensile properties of the board are improved. High tensile strength, good fire r...

Abstract

The invention discloses a plastic-wood composite panel. The plastic-wood composite panel comprises the following raw materials in parts by weight: 65-80 parts of polyvinyl chloride resin, 30-42 parts of wood powder, 8-15 parts of a silicon fire retardant, 5-7 parts of a plasticizer, 2-4 parts of a foaming agent, 8-12 parts of glass fiber, 1-3 parts of a lubricating agent and 2-4 parts of a stabilizer. Compared with traditional plastic-wood composite panels, the scheme has the advantages that the plastic-wood composite panel has relatively high tenacity, rigidity and elasticity and good fireproof performance, is applicable to high temperature and humidity areas, is firm and durable and is long in service life, and the shock resistance and the tensile strength of the panel are improved; furthermore, the plastic-wood composite panel has the advantages of environmental friendliness, no pollution, strong wood texture, smooth and fine surface, no granular sensation and the like.

Description

technical field [0001] The invention relates to the field of rubber and plastic products, in particular to a plastic-wood composite board. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. Usually, polyvinyl chloride is used instead of the usual resin adhesive, and it is mixed with more than 30% of waste plant fibers such as wood powder, rice husk, and straw to form a new composite material. Wood-based materials are processed through extrusion, molding, injection molding and other plastic processing techniques to produce panels or profiles. Plastic-wood has entered the national "Strategic Emerging Industries List" and is listed as a "new material". [0003] Plastic-wood composite board is an environmentally friendly material, which can be recycled and reused, and the raw materials are cheap and abundant. It has good benefits in reducing environmental pollution and promot...
