Environment-friendly wood-plastic composite board for decoration and preparation method thereof

Abstract

The invention provides an environment-friendly wood-plastic composite board for decoration. The environment-friendly wood-plastic composite board for decoration is prepared from the following raw materials in parts by weight: 60-65 parts of polyvinyl chloride, 15-20 parts of polypropylene, 55-60 parts of wood flour, 12-15 parts of ramie fiber, 10-12 parts of calcite powder, 5-7 parts of talcum powder, 8-10 parts of shell powder, 8-10 parts of diatomite, 5-8 parts of sepiolite powder, 3-4 parts of zeolite powder, 3-5 parts of oxidized polyethlene wax, 1-2 parts of hokutolite powder, 0.1-0.5 part of titanium dioxide, 2-3 parts of pine needle meal, 1.5-2 parts of naringenin, 1-1.5 parts of lemon grass, 2-2.5 parts of apple eucalyptus leaves, 0.5-1 part of lemon eucalyptus leaves, 2-3 parts ofcallicarpa nudiflora, 1.5-2 parts of leaves of Chinese ilex, 0.3-0.5 part of coupling agent, 4-6 parts of stabilizer, 2.5-4.5 parts of compatilizer and 0.5-1 part of ultraviolet light absorbent. Thewood-plastic composite board is an indoor decoration material with excellent comprehensive performance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an environment-friendly wood-plastic composite board for decoration and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a composite profile mainly made of wood or cellulose as the base material and plastic. Wood-plastic composite material has the advantages of woody feeling of solid wood material and weather resistance and microbial resistance of plastic matrix. And during use, it will not emit gases that are harmful to human health, that is, it will not pollute the environment, and the material itself can be reused. 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, most commonly used in the field of building decoration, and wood materials for construction need to have excellent a...

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.
