Embodiment 1

[0015] Such as figure 1 As shown, a wear-resistant and corrosion-resistant double-layer plastic pipe includes an inner layer 1 made of corrosion-resistant materials and an outer layer 2 made of wear-resistant materials. The inner layer 1 and the outer layer 2 are connected by injection molding. One piece, the inner layer 1 is a nylon layer, a polytetrafluoroethylene layer, a polypropylene layer, a polyether polyurethane layer or a PVC layer, and the outer layer 2 is a PU layer or a PE layer. Since the inner layer 1 is a nylon layer, a polytetrafluoroethylene layer, a polypropylene layer, a polyether polyurethane layer or a PVC layer, the pipe can transport acid-base gas or liquid; while the outer layer 2 is a PU layer or a PE layer , So that the outer layer 2 has high hardness, good flexibility, and strong wear resistance, and it is not easy to break during use.

[0016] When the inner layer 1 is a polyether polyurethane layer, it can make the inner and outer walls of the inner ...

Embodiment 2

[0020] A method for forming a wear-resistant and anti-corrosive double-layer plastic pipe according to Embodiment 1 includes the following steps:

[0021] Step 1. Prepare the mold for pipe molding and the corresponding inner layer 1 and outer layer 2 materials, then install the mold on the injection molding machine, and pour the inner layer 1 and outer layer 2 materials into the corresponding positions;

[0022] Step two, start the injection molding machine, the material of the inner layer 1 flows into the cavity of the mold to form the inner layer 1 structure after being melted, and then the material of the outer layer 2 flows into the cavity of the mold to form the outer layer structure after being melted. An integral structure covering the surface of the inner layer structure with the outer layer structure is obtained, and the integral structure is a double-layer plastic pipe.

[0023] It should be noted that: in the present invention, the two materials of the inner layer and the ...

Abstract

The invention belongs to the technical field of plastic pipes, in particular to a wear-resistant and anti-corrosion double-layer plastic pipe, comprising an inner layer made of corrosion-resistant materials and an outer layer made of wear-resistant materials, the inner layer and the outer layer The inner layer is connected as a whole by injection molding, the inner layer is a nylon layer, polytetrafluoroethylene layer, polypropylene layer, polyether polyurethane layer or PVC layer, and the outer layer is a PU layer or a PE layer. Because the pipeline of the present invention has the above-mentioned structure, the pipeline of the present invention has the characteristics of explosion-proof, corrosion-resistant, wear-resistant, labor-saving, convenient to install, and easy to clean. In addition, the invention also discloses a forming method of a wear-resistant and anti-corrosion double-layer plastic pipe.

Description

Technical field [0001] The invention belongs to the technical field of plastic pipes, and specifically relates to a wear-resistant and corrosion-resistant double-layer plastic pipe and a molding method thereof. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester as raw material, added with stabilizers, lubricants, plasticizers, etc., and are processed by extrusion in a pipe making machine by a "plastic" method. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction, etc., it has been used more and more widely in construction engineering. Mainly used for tap water supply system piping, drainage, exhaust and sewage sanitation pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. [0003] In the spraying industry, because spraying solutions mostly contain acid or alkali, pipes using conventio...
