Description

technical field [0001] The invention relates to a composite modified plastic-wood composite material board and a preparation method thereof, which relate to a composite material, a structural material and a preparation method thereof, and are suitable for making indoor and outdoor floors, guardrails, decorative boards and the like. 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 man...
