Manufacturing method of high-strength anti-aging cable protection pipe

Abstract

The invention provides a manufacturing method of a high-strength anti-aging cable protection pipe. The manufacturing method comprises the following steps of a, stirring, wherein 100 parts of high-density polyethylene resin, 0.8-2.2 parts of an antioxidant, 1-4 parts of a lubricating agent, 0-40 parts of a filling agent, 6-20 parts of a plasticizer, 0.5-1.5 parts of a stabilizer and 4-8 parts of color masterbatch are weighed and placed into a stirrer for stirring treatment; b, drying, wherein a mixture is dried through a drying machine; c, extrusion and molding, wherein extrusion treatment of the mixture is carried out through an extruder, and the mixture enters a mold for molding treatment after extrusion; d, shaping, wherein shaping treatment of a semi-finished pipe is carried out; e, cooling, wherein the semi-finished pipe is cooled through cooling equipment; f, cutting, wherein the semi-finished pipe is cut through slitting equipment; g, polishing, wherein an end opening of the semi-finished pipe is polished through an end opening polishing device; h, spraying, wherein surface spraying treatment of the semi-finished pipe is carried out through a surface treatment device; and i,code spraying, wherein code spraying treatment of the semi-finished pipe is carried out through an automatic code spraying machine.

Description

technical field [0001] The invention belongs to the technical field of protective tubes, and relates to a manufacturing method, in particular to a manufacturing method of a high-strength aging-resistant cable protective tube. Background technique [0002] In our daily life, we often encounter some places where protective tubes are used, including but not limited to engineering monitoring, weak current, smart technology, road lighting, etc., which are closely related to communication cables. [0003] After searching, for example, Chinese patent literature discloses a wire and cable protection tube material and the wire and cable protection tube [application number: 201410498010.2; publication number: CN104231484B]. This wire and cable protection tube material is characterized in that it includes the following components in parts by weight, 50-60 parts of high-polymerization polyvinyl chloride with a polymerization degree of 2500±200, a chlorine mass fraction of 65-68%, and a ...
