Plastic wood board with high weather resistance and processing method thereof

Abstract

The invention discloses a plastic wood board with high weather resistance, comprising a plastic wood base board. The plastic wood base board mainly takes wood flour and PVC (Poly Vinyl Chloride) raw material as main raw materials; the surface of the plastic wood base board is provided with an ASA (Acrylonitrile-Styrene-Acrylate) coextrusion layer; and the coverage range of the ASA coextrusion layer is an upper surface of the integral plastic wood board. The plastic wood board with high weather resistance can not only enable the surface of the plastic wood board to be rich in luster and the integral effect to be more attractive by matching with the inherent color of the plastic wood board, but also solve the problem of color fading of the plastic wood board used outdoors and select different models as required and has the advantages of convenient installation, low price and very well social benefit and economic benefit.

Description

technical field [0001] The invention relates to a plastic wood board, in particular to a high weather resistance plastic wood board and a processing method thereof. Background technique [0002] Plastic wood board is a composite material made of recycled plastic and natural wood fibers such as wood powder, rice husk, wheat straw, and peanut shells, which are processed by polymer improvement, compounding, and extrusion. It has the main advantages of both plastic and wood. It is used to replace natural wood in the construction industry. At present, the plastic wood panels commonly used in construction are mainly used indoors, because if they are used outdoors, they generally have the following disadvantages: [0003] 1. It is easy to fade after long-term exposure to sunlight and has poor weather resistance; [0004] 2. The service life is short, and it is necessary to brush a layer of protective oil on the outside of the plastic wood board every year, and the maintenance cost...
