Novel environmental-friendly wood-plastic composite board and preparation method thereof

Abstract

The invention provides a novel environmental-friendly wood-plastic composite board which is prepared from the following raw material components in parts by weight: 50 to 55 parts of polyethylene, 12 to 15 parts of polypropylene, 12 to 15 parts of ABS (Acrylonitrile Butadiene Styrene) plastic, 55 to 60 parts of wood meal, 12 to 15 parts of ramie fiber, 10 to 12 parts of calcite powder, 5 to 7 partsof talcum powder, 8 to 10 parts of shell powder, 8 to 10 parts of diatomite, 5 to 8 parts of sea-foam stone powder, 3 to 4 parts of zeolite powder, 1 to 2 parts of hokutolite powder, 0.1 to 0.5 partof titanium dioxide, 2 to 3 parts of pine needle meal, 1.5 to 2 parts of naringenin, 1.5 to 2 parts of thyme, 1 to 1.5 parts of tamarind shell, 2 to 3 parts of callicarpa nudiflora, 1.5 to 2 parts ofleaes of chinese ilex, 1 to 1.5 parts of schizonepeta, 0.3 to 0.5 part of coupling agent, 4 to 6 parts of stabilizer and 2.5 to 4 parts of compatilizer. The wood-plastic composite board provided by the invention has an excellent mechanical property and an antibacterial anti-mold property and is an indoor decorative material with excellent comprehensive performance.

Description

Technical field [0001] The invention relates to the field of composite materials, in particular to a novel environmentally friendly wood-plastic composite board and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a composite profile mainly made of wood or cellulose as the basic material and plastic. Wood-plastic composite material has the advantages of woodiness of solid wood material and weather resistance and microbial resistance of the plastic matrix. And during use, it will not emit gases that are harmful to human health, that is, it will not pollute the environment. The material itself can be reused and recycled. It is a brand-new green product and an ecologically clean composite material. [0003] At present, wood-plastic composite materials have begun to replace solid wood and are widely used in various fields, the most common being used in the field of construction and decoration, and wood materials for construction need to hav...

AI Technical Summary

Problems solved by technology

Although wood fibers in wood-plastic composites are coated in a plastic matrix, they have better anti-microbial degradation ability than natural wood, but due to the large difference in surface polarity between wood fibers and plastics, even if added in composite processing Without a compatibilizer, there are still a large number of pores on the two-phase interface inside the material, and the pores are usually interconnected. Wood fibers absorb water through these pores and will be contaminated by microorganisms and then degraded by microorganisms. Microorganisms will reproduce inside the material. , eventually leading to structural damage to the material, corroded

[0004] In addition, with the development of society, people's demand for multifunctional materials is increasing, and most of the existing wood-plastic composite materials have single functions and only have simple decorative effects, which can no longer meet people's requirements.
