Embodiment Construction

[0015] The tool torque M reaches M ｍｉｎ +10% (M ｍａｘ - M ｍｉｎ ) time corresponds to the glue burning time of the rubber material; define t90, that is, the torque M of the vulcanizer reaches Ｍｍｉｎ +90% (M ｍａｘ - M ｍｉｎ ) is the positive vulcanization time of the rubber. According to the vulcanization curve, it can be seen that the change trend of the rubber vulcanization degree is consistent with the data of the compression set value, and the data of the compression set reflects the rubber from under-vulcanization to positive vulcanization The process of gradually increasing the degree of sulfidation.

Abstract

A cable composite cross-linking process belongs to the technical field of cable manufactures. The invention discloses a cable composite cross-linking process method comprising using a cable insulatedwire core outer extruded tube extrusion radiation cross-linking material as an isolation layer; subjecting the insulated wire core to a vulcanization cross-linking process; subjecting the isolation layer to a irradiation cross-linking process; subjecting sheath rubber to a under-sulfur process; and performing a secondary cross-linking process to eliminate electric charges such that the sheath is completely cross-linked. The method solves the high elasticity and the deformation liableness of a rubber material, and solves the possibility of residual charges in the irradiation cross-linking, so that the cable is fully cross-linked. The process technology of combining vulcanization cross-linking with irradiation cross-linking technologies not only retains the advantages of the respective cross-linking technologies, but also compensates for the defects of the respective cross-linking technologies.

Description

technical field [0001] A cable composite crosslinking process belongs to the technical field of cable manufacturing. Background technique [0002] Cross-linked materials have been widely recognized for their good chemical resistance stability, superior mechanical properties, and stable material structure. [0003] Due to its excellent low temperature resistance, oil resistance, acid and alkali resistance and other harsh environment performance, rubber material cable products have been widely used in automobile, petroleum, aerospace and other industrial fields to make various hoses, sealing rings, gaskets and other products, and have also been widely used In all fields of military and civilian production. The vulcanization and cross-linking of rubber cables in the manufacturing process uses water vapor pressure to control the degree of cross-linking by using the pressure and temperature of saturated water vapor. Extrusion and cross-linking are completed simultaneously, so th...
