Outdoor high-weather-resistance polycarbonate plastic-wood composite board for building purposes

Abstract

The invention discloses an outdoor high-weather-resistance polycarbonate plastic-wood composite board for building purposes. The outdoor high-weather-resistance polycarbonate plastic-wood composite board is prepared from the following components in parts by weight: 80-90 parts of polycarbonate, 60-70 parts of locust tree wood flour, 10-15 parts of EVA, 3-5 parts of titanium dioxide, 3-7 parts of triallylisocyanurate, 5-10 parts of nilox resin, 2-3 parts of TOTD, 2-3 parts of ethylene thiourea, 3-9 parts of epoxidized soybean oil, 6-15 parts of calcium stearate, 6-15 parts of dibasic lead phosphate, 2-4 parts of sodium pyrophosphate and 8-12 parts of 4,4'-thiobis(6-tertiary-butyl-3-methylphenol). The outdoor high-weather-resistance polycarbonate plastic-wood composite board provided by the invention is good in tenacity, rigidity and elasticity, firm, durable and long in service life, and can resist various severe climates outdoors; moreover, the board has the advantages of environmental protection, no pollution, high wood texture, smooth and fine surface, no granular sensation and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an outdoor highly weather-resistant polycarbonate wood-plastic composite board. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly building material that has only emerged in recent years, and it has just started abroad. The raw materials used in wood-plastic products can be used as base materials such as waste plastics, waste wood, agricultural and forestry straw and other plant fibers, and do not contain any additional harmful ingredients. Moreover, it can be recycled and reused, which can be called a novel product of environmental protection, energy saving, and resource recycling in the true sense. [0003] "Wood-plastic material", also called "wood-plastic composite material", as the name suggests, can be understood as mainly using plastic as raw material, adding wood powder, rice husk, straw and othe...

Problems solved by technology

However, plastic-wood composite panels also have some disadvantages, such as long-term use, especially in the open air, it is easy to fade after long-term sunlight exposure, and the weather resistance is poor; the service life is short, and a layer of protective oil needs to be applied to the plastic-wood composite panels every year, and the maintenance cost is high.
