Abstract

The invention discloses a high-plant fiber content wood-plastic composite material. The high-plant fiber content wood-plastic composite material comprises the following raw materials in parts by weight: 30-50 parts of PVC resin powder, 30-50 parts of plant fiber powder, 0.3-2 parts of a coupling agent, 1-5 parts of a plasticizing regulator, 2-6 parts of an environment-friendly stabilizer, 1-3 parts of a processing aid, 1-3 parts of a lubricating agent and 1-5 parts of a toughening agent. The high-plant fiber content wood-plastic composite material prepared according to a formula provided by the invention has the elongation at break of 2-7%, the bending strength of 25-35 MPa, the Shore hardness of 71-80 HD and the moisture content of 0.2-0.8% which are far higher than physical and chemicalperformance indexes of the wood-plastic composite material stated in Chinese standard GB / T24137; the dimensional stability is greatly improved; the problem that the wood-plastic composite material iseasy to deform during using is solved, agricultural and forestry wastes are fully utilized, the wastes are turned into treasures, and high-value utilization of waste plant fiber resources is achieved.

Description

technical field

[0001] The invention belongs to the technical field of wood-plastic composite materials. More specifically, it relates to a wood-plastic composite material with high plant fiber and its preparation method. Background technique

[0002] Wood-plastic composite material is a new type of environmentally friendly composite material made of plant fiber powder (wood powder, straw, forestry three residues, etc.) and thermoplastics as the main raw materials through high-tech processes such as physics, chemistry and biological engineering. Its zero formaldehyde, insect resistance, corrosion resistance, chemical reaction resistance, low water absorption and other advantages of both wood and plastic make it widely used in transportation, interior decoration, construction, furniture products, garden landscape and other fields.

[0003] The promotion and application of wood-plastic composite materials can solve the problem of environmental pollution caused by waste plasti...
