Abstract

The invention relates to an improved wood-plastic composite material and a preparation method thereof. The improved wood-plastic composite material consists of the following components in part by mass: 30 to 80 parts of thermoplastic plastics, 30 to 70 parts of plant fiber powder, 5 to 30 parts of vermiculite powder, and 2 to 10 parts of interface modifying agent, wherein the vermiculite powder is non-expanded natural vermiculite powder and has the fineness of 100 to 500 meshes; and the thermoplastic plastics are new thermoplastic plastics or waste thermoplastic plastics. The components are premixed, plasticized and granulated to form the improved wood-plastic composite material. The vermiculite powder has the function of a common filler, and also can obviously improve the toughness, strength and rigidity of the wood-plastic composite material, so that the application range of the wood-plastic composite material is widened. The product is low in cost and meets the environmental protection requirement.

Description

technical field

[0001] The invention relates to an improved wood-plastic composite material and a preparation method thereof. Background technique

[0002] Using plastic instead of wood, especially waste plastic and waste plants as raw materials, to prepare wood-plastic composite materials to replace wood is an important way to solve environmental problems and wood shortages. Wood-plastic composite materials can make full use of low-value resources to produce high value-added products, and can find the best performance position for our resources such as manpower, capital, and raw materials. In the previous preparation process of wood-plastic composite materials, calcium carbonate, talcum powder, kaolin and other mineral fillers are usually added to improve the modulus, dimensional stability and heat resistance of wood-plastic composite materials. However, its improvement effect is still not very satisfactory. Contents of the invention
