Problems solved by technology

The traditional aluminum-plastic composite pipe, because the inner and outer layer matrix resin is made of polyethylene, has poor heat resistance, and the hot melt adhesive joints of the pipes are prone to delamination when heated, so they cannot be applied to heat sink pipes, and are more used in Low temperature hot water floor radiant heating system

Embodiment 1

[0035] An antibacterial, anti-scaling, and high-temperature-resistant aluminum-plastic composite pipe. The inner layer of the pipe is a modified PB material added with antibacterial masterbatch and anti-scaling masterbatch. The third layer is an aluminum alloy layer, and the outermost layer is PB resin. The inner and outer layers of the pipe are bonded to the third layer by high temperature resistant hot melt adhesive. in:

[0036] The first layer 1 of the pipe is the inner layer of the pipe, which is a modified PB resin added with antibacterial masterbatch and anti-fouling masterbatch, accounting for 58% of the entire wall thickness. Among them, the antibacterial masterbatch is obtained by mixing and granulating nano-copper powder with a particle size of 200nm and PB resin; the anti-fouling masterbatch is obtained by mixing and granulating silicone powder and PB resin. Among them, the silicone powder is a homogeneous mixture obtained under strong shear conditions of 40% silo...

Embodiment 2

[0048] An antibacterial, anti-scaling, and high-temperature-resistant aluminum-plastic composite pipe. The inner layer of the pipe is a modified type II PE-RT pipe added with antibacterial masterbatch and anti-scaling masterbatch. The third layer is an aluminum alloy layer, and the outermost layer is It is type II PE-RT base material, and the inner and outer layers of the pipe are bonded with the third layer by high temperature resistant hot melt adhesive. in:

[0049] The inner layer of the pipe is a modified type II PE-RT resin added with antibacterial masterbatch and anti-fouling masterbatch, accounting for 58% of the entire wall thickness. Among them, the antibacterial masterbatch is obtained by mixing and granulating nano-silver ion antibacterial agent with type II PE-RT resin; The resin is obtained by mixing and granulating. Then the antibacterial masterbatch, anti-fouling masterbatch and PE-RT resin base material are blended, the nano silver ion antibacterial agent ac...

Abstract

The invention relates to a bacteriostatic, anti-scaling and high-temperature-resistant aluminum-plastic composite pipe. The bacteriostatic, anti-scaling and high-temperature-resistant aluminum-plasticcomposite pipe is characterized in that an inner layer of a pipe is made of a modified high-temperature-resistant polyolefin material with bacteriostatic and anti-scaling functions, a second layer ismade of a high-temperature-resistant hot melt adhesive, a third layer is made of middle layer aluminum alloy, a fourth layer is made of a high-temperature-resistant hot melt adhesive, and the fifth layer is made of a high-temperature-resistant polyolefin material; the inner layer of the pipe comprises an antibacterial and anti-scaling modified material, and the antibacterial and anti-scaling modified material is nano antibacterial master batch and anti-scaling master batch; and the anti-scaling master batch is prepared from polytetrafluoroethylene fine powder, siloxane copolymer and siliconepowder. One or more of polytetrafluoroethylene fine powder and silicone powder are selected as anti-scaling materials and introduced into the inner layer of the pipe, the roughness of the inner wall of the pipe is reduced, and attachment of incrustation is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of pipes, in particular to an antibacterial, anti-scaling and high-temperature-resistant aluminum-plastic composite pipe. 【Background technique】 [0002] In recent years, with the substantial improvement of the national economy, people's living standards have also been greatly improved, especially in the choice of winter heating equipment, many people choose high heating efficiency, comfortable and healthy radiators. Due to the high temperature of the conveying fluid (above 70°C), the heat sink pipe needs to have good high temperature resistance and pressure resistance. Heat sink pipes on the market are mostly made of heat-resistant polyethylene (PE-RT), cross-linked polyethylene (PE-X), random copolymerized polypropylene (PP-R) or polybutene resin (PB) and other materials production. However, after these pipes have been used for several heating seasons, it is often found that the inner wall of the pipes...
