Problems solved by technology

However, in the prior art, when the AA1100 aluminum alloy is used to prepare the aluminum alloy sheet, the mechanical properties of the product fluctuate greatly, which leads to a decrease in the yield of the aluminum alloy sheet, resulting in a low pass rate of the aluminum-plastic composite pipe prepared by using the aluminum alloy sheet

Abstract

The invention discloses an anti-corrosion aluminum-plastic composite pipe. The anti-corrosion aluminum-plastic composite pipe comprises an inner layer pipe body, a middle layer pipe body and an outer layer pipe body. The inner layer pipe body and the outer layer pipe body are alloy pipes. The middle layer pipe body is formed by squeezing mixed wood-plastic composite into a cavity between the inner layer pipe body and the outer layer pipe body. By the adoption of the mixed wood-plastic composite, the performance of the composite pipe can be improved obviously, the prepared middle layer plastic pipe body has good strength and toughness, and corrosion resistance is good; and moreover, cost can be greatly reduced, and the application range of the aluminum-plastic pipe is widened.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic composite pipes, in particular to a corrosion-resistant aluminum-plastic composite pipe. Background technique [0002] Aluminum-plastic composite pipe is a new type of pipe made of longitudinally welded aluminum pipe in the middle, polyethylene material for inner and outer layers, and hot-melt co-extrusion between layers. The inner and outer layers of polyethylene are easy to form, have good corrosion resistance and low temperature resistance, and have excellent low temperature impact resistance. Pipe grade polyethylene also has high long-term pressure resistance and environmental stress cracking resistance. The middle layer longitudinally welded aluminum alloy pipe has the compressive strength and impact resistance of metal. In the actual use temperature range of the aluminum-plastic pipe, the strength of the aluminum alloy remains unchanged, which provides a reliable guarantee for the l...
