Abstract

The invention relates to an insulation rubber for cables, which is prepared by the following materials measured in mass percentage: 39.14 percent of EPDM (Ethylene-Propylene-Diene Monomer), 3.52 percent of zinc oxide, 0.97 percent of antiager RD, 1.96 percent of paraffin, 0.39 percent of stearic acid, 0.78 percent of silane coupling agent A-172, 15.66 percent of superfine French chalk, 11.74 percent of calcium powder, 15.66 percent of calcinated argil, 3.52 percent of white carbon black, 2.94 percent of paraffin oil, 1.76 percent of vulcanizing-agent dicumyl peroxide, and 1.96 percent of crosslink agent TAIC (triallyl isocyanurate). The insulation rubber for cable has low manufacturing cost, the tensile intensity before aging is 8.5 N / mm 2, and the elongation at break before aging is 350 percent.

Description

Technical field: [0001] The invention relates to an insulating rubber for cables. Background technique: [0002] With the advancement of technology, insulating rubber for cables is used in various industries and fields, and the demand is increasing. Ethylene-propylene rubber has become an insulating material widely used in the wire and cable industry because of its many advantages. Its production cost is relatively high, and its production and use are subject to certain restrictions. Invention content: [0003] In order to overcome the deficiencies in the background technology, the present invention provides an insulating rubber for cables, which has low production cost and a tensile strength of 8.5N / mm before aging 2 , The elongation at break before aging is 350%. [0004] The technical solution of the present invention is: the insulating rubber is made of the following raw materials, each raw material is calculated by mass percentage: EPDM rubber 39.14%, zinc oxide 3.5...
