Aluminum-plastic wood sectional material

Abstract

The invention provides an aluminum-plastic wood profile, comprising a wood-plastic layer and an aluminum alloy layer; the wood-plastic layer is composed of the following raw materials in parts by weight: 10-30 parts of sarin resin, 5-15 parts of plant fiber powder, wood powder 40-50 parts, 20-40 parts of polyurethane foam powder, 5-15 parts of inorganic filler, 3-10 parts of flame retardant, 1-3 parts of lubricant, 0-2 parts of antioxidant, ethylene-vinyl acetate copolymer 2-7 parts of mixture with ethylene-acrylic acid copolymer, 1-3 parts of cold resistance agent M711, 1-2 parts of light stabilizer GW-540, 5-15 parts of inorganic filler, 3-10 parts of flame retardant, 1 part of lubricant ‑5 parts, 1‑3 parts of colorant, 3‑10 parts of bentonite, 20‑40 parts of low density polyethylene. In the present invention, the wood-plastic layer and the aluminum alloy layer are used in combination, and the advantages and disadvantages of the wood-plastic layer and the aluminum alloy layer are complemented. Weather resistance, wear resistance and other properties, in the natural environment, aluminum-plastic wood profiles have good mechanical properties, are not easy to age, and have a long service life.

Description

technical field [0001] The invention relates to the technical field of door and window materials, in particular to an aluminum-plastic wood profile. Background technique [0002] The current door and window profiles (frames, fans or stiles) are either plastic profiles, aluminum alloy profiles, or wood profiles; aluminum alloy profiles are widely used in various window structure. The aluminum alloy door frame is a door frame component made of surface-treated aluminum alloy profiles through blanking, drilling, milling, tapping, manufacturing and other processing processes, and then used with connectors, sealing materials and opening and closing hardware accessories Assembled. Because it is directly made of aluminum alloy, it is very easy to be scratched by foreign objects during use, causing the surface of the aluminum alloy door frame to be damaged, the appearance is not beautiful, and the service life is short. And aluminum alloy profiles have poor thermal insulation perf...

AI Technical Summary

Problems solved by technology

Because it is directly made of aluminum alloy, it is very easy to be scratched by foreign objects during use, resulting in damage to the surface of the aluminum alloy door frame, unsightly appearance and short service life

Moreover, the aluminum alloy profile has poor heat insulation performance and poor energy saving effect

Although plastic profiles have good heat insulation performance, they have poor weather resistance and wear resistance. In the natural environment, after a period of time, the surface loses its original luster and fades quickly, and after a period of use, the exposed parts are easy to age and have poor rigidity.
