Method for producing microwave vulcanization rubber-sheathed cable

Abstract

The invention relates to a production method for microwave vulcanization cabtyre cables, belonging to the cable production technical field. The main process of the method is that: conductors are let off evenly and steadily through a pay-off stand; sheaths of the cables are extruded through an extruder; the cables coated with sheaths are heated up to 130-160 DEG C through microwave for vulcanization; the vulcanization temperature of 130-160 DEG C is kept, and the cables are vulcanized continuously through hot-air vulcanization equipment; after the vulcanization is finished, the cables are cooled in normal temperature; the microwave vulcanization cabtyre cables can be obtained by passing a take-up reel and a take-up spool. The microwave vulcanization technology is adopted to replace the prior steam curing process, thereby reducing production cost and improving production efficiency; the microwave vulcanization is combined with the hot-air vulcanization, not only the technical requirements of the cables can be guaranteed, but also waste of energy is reduced; an infrared temperature controller is used to monitor vulcanized objects, thereby preventing the sheaths of the cables from being overvulcanized.

Description

technical field [0001] The invention relates to a production method of a cable, in particular to a production method of a microwave vulcanized rubber-sheathed cable. Background technique [0002] The insulating material of 1-10KV vulcanized rubber cables is mainly rubber. Raw rubber becomes soft when heated, becomes hard and brittle when cold, is not easy to form, easy to wear, and is easy to dissolve in organic solvents such as gasoline. It has double bonds in the molecule and is easy to add. reaction, easy aging. In order to improve the performance of rubber products, a series of processing processes must be carried out on the raw rubber in production. Under certain conditions, the raw rubber in the rubber compound and the vulcanizing agent undergo a chemical reaction to make it cross-linked by a linear structure of macromolecules. It becomes a macromolecule with a three-dimensional network structure, so that the insulating material has excellent properties such as high s...
