Wood-plastic composite material with PP powder

Abstract

The invention discloses a wood-plastic composite material with PP (Polypropylene) powder. The wood-plastic composite material comprises the following raw materials in percentage by weight: 34.2-36.8% of a HDPE (High-Density Polyethylene) matrix, 9-11.3% of PP powder, 38.6-42% of wood powder, 3-5% of lubricating agent, 0.02-0.8% of anti-ultraviolet agent, 2-4% of compatilizer, 2-4% of oxide pigment, 1.5-3% of stabilizer and 2-4% of anti-aging agent. Through the improvement of the prescription and the process, the PP powder is added in the HDPE matrix so that the strength of the wood-plastic composite material is enhanced. The wood-plastic composite material disclosed by the invention has the advantages of good mechanical strength, rigidity, hardness and wear-resisting property. The surface is smooth and the water absorption is obviously reduced, so that the waterproof effect of the wood-plastic composite material is enhanced and the wood-plastic composite material is more widely applied to various places.

Description

Technical field [0001] The invention belongs to the field of chemical industry, in particular to a plastic wood material added with PP powder. Background technique [0002] Plastic wood, as the name suggests, is a combination of plastic and solid wood. It not only maintains the affinity of solid wood, but also has good moisture resistance, water resistance, acid and alkali resistance, fungus inhibition, and antistatic properties. A series of wood-plastic composite materials produced from wood chips, straw, waste plastics and other wastes are gradually entering the fields of decoration and construction. At present, the main products are mixed with HDPE and wood powder, but the compatibility of the system is poor after wood powder is mixed, which makes the strength of the product decrease and the appearance is not smooth. [0003] In addition, traditional wood-plastic products have a shortcoming: non-wearing and insufficient surface hardness, which makes the surface pattern easy to ...

AI Technical Summary

Problems solved by technology

At present, the main product is mixed with HDPE and wood powder, but due to the poor compatibility of the system after adding wood powder, the strength of the product is reduced and the appearance is not smooth.

[0003] In addition, traditional wood-plastic products have a shortcoming, which is not wear-resistant and the surface hardness is not enough, which makes the surface pattern easy to wear during processing.
