Abstract

The invention discloses a novel wood-plastic composite material. The wood-plastic composite material comprises the following components in parts by weight: 40-60 parts of PVC powder, 40-60 parts of heavy calcium carbonate powder, 10-20 parts of talcum powder, 12-20 parts of wood powder, 1.5-3.5 parts of a stabilizer, 3-6 parts of a modifier, 0.5-2 parts of acrylate, 0.1-1 part of an inner lubricant and 0.2-0.7 part of an outer lubricant. The novel wood-plastic composite material disclosed by the invention has excellent properties in the aspects of static bending strength, impact resistance andthe like.

Description

technical field [0001] The invention relates to a wood-plastic material, in particular to a novel wood-plastic composite material. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly composite material, which has received widespread attention at home and abroad in recent years. Generally speaking, it is a board or profile produced by mixing thermoplastics such as polyethylene, polypropylene, and polyvinyl chloride with plant fibers such as wood flour, rice husk, and straw, and then extruding, injection molding, and molding. Wood-plastic composites have the advantages of both wood and plastic. It not only has the appearance like natural wood, but also overcomes its shortcomings. It has the advantages of anti-corrosion, moisture-proof, moth-proof, high dimensional stability, etc. It is harder than pure plastic, and it has a processability similar to wood, which can be cut and bonded. Fastened connections with nails or bolts...
