Abstract

The invention relates to the technical field of cables, in particular to a high-strength and high-elongation flame-retardant rubber insulated cable material as well as processing equipment and a process thereof, and solves the defects that in the prior art, a vulcanizing agent DCP, a vulcanization accelerator TAC and a rubber compound are relatively low in elongation at break (the elongation at break is generally 150-250%), the process range in the vulcanization process is relatively narrow, and the production cost is relatively low. And the elongation at break is easily unqualified during steam vulcanization. The invention discloses a high-strength high-elongation flame-retardant rubber insulated cable material and processing equipment and process thereof. The cable material comprises 2.2-2.8 parts of calcium lactobionate, 93-99 parts of ethylene-vinyl acetate copolymer, 4.5-5.9 parts of SG-1 polyvinyl chloride resin, 1.2-1.9 parts of zinc pyrithione, 0.1-0.4 part of polyethylene acid, 1-2 parts of azodiisobutyronitrile, 1-2 parts of hydrogenated castor oil, 4-5 parts of torispherical silica powder and 2-3 parts of charcoal dust. The heat resistance and weather resistance of the rubber compound can be improved, finally, CPE serves as a part of a base material, due to the fact that molecular chains of CPE contain chlorine elements, CPE is heated and decomposed to generate non-combustible gas, and the flame retardant effect is achieved by diluting the combustible gas and oxygen.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength and high-elongation flame-retardant rubber insulating cable material and its processing equipment and technology. Background technique [0002] With the rapid development of economic construction, the continuous improvement of people's living standards, and the rapid development of various urban and rural infrastructures, the demand for various types of cables is increasing. Therefore, it is very important to continuously improve the quality of cables. Rubber insulation is commonly used in The EPDM is used as the base material. [0003] However, with the vulcanizing agent DCP and the vulcanization accelerator TAC, the disadvantages of the rubber compound are: the elongation at break is low (the elongation at break is generally 150% to 250%), and the process range during the vulcanization process is narrow. It is easy to fail the elongation at break. SUMMARY OF T...
