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.

[0016] Insulated wire core vulcanization and cross-linking process

[0017] Through the torque rheometer, measure the torque M of the vulcanizer to reach M ｍｉｎ +10% (M max - M min ) The corresponding time is the glue burning time of the rubber material; define t 90 That is, the torque M of the vulcanizer reaches M ｍｉｎ +90% (M max - M min ) The corresponding time is the pos...

Abstract

A cable compound cross-linking process belongs to the technical field of cable manufacturing. The invention discloses a cable compound cross-linking process method: the outer extruded tube-type extruded radiation cross-linked material of the cable insulation core is used as the isolation layer, and the insulation core is used Vulcanization and cross-linking process, using radiation cross-linking process for the isolation layer, after using the under-sulfur process for the sheath rubber, and finally performing a secondary cross-linking process to eliminate charges, and the sheath is completely cross-linked, which solves the problem of elasticity due to the characteristics of the rubber material. It is large and easy to change, and it solves the possibility of residual charge in radiation cross-linking, so that the cable can be fully cross-linked. The process technology that combines vulcanization crosslinking and irradiation crosslinking technology not only retains the advantages of each crosslinking, but also makes up for the defects of each crosslinking.

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...
