Multifunctional polyethylene and stainless steel composite pipe

Abstract

The invention relates to an UHMW-PE (ultrahigh molecular weight polyethylene) pipe, in particular to a multifunctional polyethylene and stainless steel composite pipe formed by compositing the UHMW-PE pipe and stainless steel, and a preparation method of the composite pipe. The UHMW-PE pipe comprises the following components in parts by weight: 100 parts of UHMW-PE, 10-15 parts of diatomite, 8-10 parts of short glass fiber, 7-10 parts of calcium bicarbonate, 7-10 parts of organic tin, 1-5 parts of nano aluminum nitride, 1-2 parts of graphite, 0.1-1.5 parts of PE wax, 2-5 parts of acrylic ester, 3-5 parts of silicone polymer, 3-6 parts of titanium dioxide, 6-10 parts of shock-resistance MBS (methyl methacrylate-butadiene-styrene copolymer) resin, 0.5-1.0 parts of antioxygen 1010, and 3-5 parts of light absorption agent FeMnOx composite oxide. The composite pipe comprises an UHMW-PE inner pipe and a stainless steel outer pipe between which hot glue adhesion layer is adhered, wherein a SiO2 composite coating is coated on the outer surface of the stainless steel pipe. The multifunctional polyethylene and stainless steel composite pipe disclosed by the invention has the advantages of convenience in installation, good performance and wide application.

Description

technical field [0001] The invention relates to the field of polyethylene pipes, in particular to a multifunctional polyethylene-stainless steel composite pipe and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, environmental protection awareness and health concerns, a green revolution in the building materials industry has been set off in the field of water supply and drainage. According to a large amount of water quality monitoring data, it is shown that after using cold-galvanized steel pipes, the general service life is less than 5 years before rusting, and the iron smell is serious. Residents have complained to government departments, causing a social problem. Compared with traditional metal pipes, plastic pipes have the characteristics of light weight, corrosion resistance, high compressive strength, sanitation and safety, small water flow resistance, energy saving, metal saving, improved living environm...

Problems solved by technology

Although the development situation is good, there are many domestic pipe manufacturers for transporting fluid substances, but the products are also uneven. Most of the pipes show that the strength of flexible pipes is not enough, the scaling problem is serious, and even the pipes leak frequently, causing destructive accidents.
