Abstract

The invention discloses a preparation process of an enhanced plastic pipeline material. The preparation process comprises the following steps that S1, materials are prepared; S2, material mixing is conducted, S3, melting is conducted, specifically, a blended material is molten by using a plastic extruder, and the molten material is output outwards; S4, extruding is conducted, specifically, the molten material is extruded and formed, and a formed pipe blank is output; S5, setting is conducted, specifically, the diameter of the extruded pipe blank is fixed; and S6, cooling is conducted, specifically, the formed product is cooled through a pipe forming cooling spraying device. According to the preparation process, polyvinyl chloride is adopted as a pipe base material, the base material is subjected to toughening and enhancing treatment through reinforcing filler, so that the obtained pipe has excellent mechanical property and corrosion resistance, meanwhile, the specially-made pipe forming cooling spraying device is adopted for cooling the formed pipe, so that the pipe can be uniformly cooled, the quality of a plastic pipeline is guaranteed, the recycling purpose of a water resourcecan be further achieved, and the process is simple and feasible, and has a wide application range.

Description

technical field [0001] The invention belongs to the technical field of plastic pipeline materials, and in particular relates to a preparation process of reinforced plastic pipeline materials. Background technique [0002] Plastic pipes are an important part of chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. In recent years, chemical building materials have made great progress and developed rapidly. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe networks. However, plastic pipes generally have the defects of low rigidity, poor dimensional stability, and prone to creep an...
