Problems solved by technology

But even so, there are some obvious deficiencies in the use of wood-plastic composite materials. For example, most of the wood-plastic composite materials currently on the market have low static bending strength and are easily deformed during use.

Abstract

The invention discloses a modified plastic-wood composite material plate and a preparation method thereof. The composite material plate is prepared from the following raw materials in parts by weight: 100 parts of modified wood flour, 60 parts of polyvinyl chloride plastic particles, 10 parts of maleic anhydride grafted plastic particles, 8 parts of modified red mud, 5-9 parts of calcium carbonate powder, 3-5 parts of calcium stearate, 2-5 parts of chlorinated polyethylene, 0.5 part of a foaming agent and 0.5 part of an antioxidant. According to the invention, the amount of used plastic is reduced, and the plate is more environment-friendly, higher in modulus, higher in rigidity, better in creep resistance, water-resistant, corrosion-resistant, termite-resistant, particularly used outdoors, not easy to crack and rot, longer in service life, higher in static bending intensity and the like, and reduced in water absorption thickness expansion.

Description

technical field [0001] The invention relates to the technical field of plate preparation, in particular to a modified wood-plastic composite material plate and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a composite material made of plastic and wood fiber (or natural fiber such as rice husk, wheat straw, corn stalk, peanut shell, etc.) with a small amount of chemical additives and fillers, and processed by special compounding equipment. It has both the main characteristics of plastic and wood, and can replace plastic and wood in many occasions. It has high strength and hardness, is not easy to wear, acid and alkali resistant, does not deform, does not contain formaldehyde, and is easy to recycle. It can be made into various cross-sections. Shape and size, different colors can be manufactured according to needs, long service life, etc., can be widely used as outdoor floor, swimming pool edge, flower box, tree pool, fence, tra...
