Abstract

The invention provides composite ecological wood. The wood comprises the following compositions in percentage by weight: 35 to 40 percent of wood meal, 40 to 49 percent of PVC, 2 to 3 percent of calcium carbonate, 4 to 6 percent of a foaming regulator, 4 to 6 percent of a stabilizing agent, 4 to 6 percent of impact-resistant ACR, 0.5 to 1.5 percent of a processing additive ACR, 0.2 to 0.4 percent of toner, an internal lubricant and an external lubricant, a foaming agent accounting for 0.1 to 1 percent of the PVC and a coupling agent accounting for 3 to 5 percent of the wood meal; and when a product is used outdoors, the product also comprises an antioxidant, an ultraviolet absorbent and a light stabilizing agent which have 0.1 to 0.5 percent of weight portions respectively. Compared with the prior art, the composite ecological wood thoroughly overcomes the disadvantages of raw wood, improves the shortage of the raw wood and keeps the particular wooden texture of the raw wood; simultaneously, for the addition of the antioxidant, the ultraviolet absorbent and the light stabilizing agent, the composite ecological wood also prevents photooxidation, fading, cracking and the like caused by ultraviolet irradiation, increases the weather resistance and prolongs the service life.

Description

(1) Technical field [0001] The invention relates to a building material, in particular to a compound ecological wood of a certain shape, which is made by mixing resin and wood fiber material in a certain proportion, and then making it into a certain shape through high temperature, extrusion, molding and other processes. (2) Technical background [0002] With the rapid development of high-rise buildings in our country, various fireproof materials such as indoor suit door materials and composite materials continue to emerge. However, most of the existing plastic reinforcing fillers on the market are calcium carbonate and glass fiber, accounting for 40% and 31% respectively, and some other inorganic fillers such as talcum powder, glass microspheres, etc., these traditional fillers make the composite very difficult. Large performance variations, and the cost of these fillers is relatively high. In the past few years, some natural organic reinforcing fillers such as cellulose fi...
