Problems solved by technology

[0003] The existing hot spring delivery pipes are generally metal pipes, which are easy to corrode and rust, and have poor thermal insulation
Moreover, metal pipes are hard pipes, and the process of handling and installation is cumbersome. It needs to be welded and installed, and the welding process is easy to damage the anti-rust layer of the metal.
The above-mentioned unfavorable phenomena lead to a short service life of metal pipes, high maintenance costs, and easy separation of heavy metal components in the pipes to hot springs, causing harm to the human body

Embodiment 1

[0034] Embodiment 1 provides a PB composite pipe, which is a three-layer composite structure. From the outside to the inside, it is an anti-corrosion outer layer A, an insulation layer B and a working inner layer C. The wall thickness of the anti-corrosion outer layer is 0.5mm, and the insulation layer The wall thickness of the wall is 8mm, and the wall thickness of the working inner layer is 3.1mm. The anti-corrosion outer layer and the insulation layer are bonded by a film coating process, and the insulation layer and the working inner layer are bonded by an adhesive.

[0035] Specifically, the anti-corrosion outer layer is made of high-density polyethylene material. The high-density polyethylene material is composed of the following components by weight: 95 parts of HDPE (HDPE 6100M), 0.2 part of antioxidant 1010, 0.1 part of antioxidant 168, 0.2 part of ultraviolet absorber 770, 0.1 part of ultraviolet absorber 944, 0.3 parts of PE wax (dispersant), 5 parts of MBS (anti-im...

Abstract

The invention discloses a PB composite pipe and a preparation method and application thereof, and belongs to the technical field of pipes. The PB composite pipe sequentially comprises an anti-corrosion outer layer, a heat preservation layer and a working inner layer from outside to inside, the working inner layer is made of polybutylene materials, the heat preservation layer is made of polyethylene foaming plastic, and the anti-corrosion outer layer is made of high-density polyethylene materials. The PB composite pipe not only has excellent compressive strength, weather resistance and stress cracking resistance, long service life and good heat preservation performance, but also has good flexibility, can be connected and installed in a hot melting mode, is easy to construct and operate, obviously reduces installation cost and maintenance cost, and is an ideal hot spring conveying pipe.

Description

technical field [0001] The invention belongs to the technical field of pipes, and in particular relates to a PB composite pipe and its preparation method and application. Background technique [0002] With the improvement of people's living standards, hot springs are becoming more and more popular because they can bring relaxation, health and entertainment to people. Hot springs are mineral springs containing a variety of trace elements that are beneficial to human health. They have a certain degree of salinity and contain minerals such as silicic acid, sulfur, and calcium. Ability is required. [0003] Existing hot spring delivery pipes are generally metal pipes, which are easy to corrode and rust, and have poor thermal insulation. Moreover, the metal pipe is a hard pipe, and the handling and installation process is cumbersome, and it needs to be welded and installed, and the welding process is easy to damage the rust-proof layer of the metal. The above-mentioned unfavor...
