Welding machine cable material adopting single covering layer and preparation method thereof

Abstract

The invention relates to a welding machine cable material adopting a single covering layer and a preparation method thereof, and belongs to the technical field of cables. The technical scheme is that the welding machine cable material comprises the following main components: 90-105 parts of chlorinated polyethylene rubber, 20-30 parts of ethylene propylene rubber, 0.5-1 part of poly(1,2-dihydro-2,2,4-trimethylquinoline), 5-8 parts of low-molecular polyethylene wax, 1-3 parts of antimony trioxide, 10-15 parts of dioctyl phthalate, 3-4 parts of dicumyl peroxide, 2-3 parts of triallyl isocyanurate and 0.5-1.5 parts of N,N'-1,3-metaphenylene bismaleimide. According to the welding machine cable material and the preparation method, the chlorinated polyethylene rubber and ethylene propylene rubber are taken as the base materials, double functions including insulation and sheathing are considered, the cable material has characteristics of the flame retardant level A, has good electric insulation property, passes the 1,000 V finished product voltage test, has wear-resisting, oil-resisting and soft characteristics and meets all requirements in the national standard GB/T5013.1 for SE3 and SE4 materials, the tensile strength is higher than 12 Mpa, the cost is about half of that of SE4 neoprene in the corresponding period or other equivalent synthetic elastomer mixture, so that the cable material has great competitive advantage in market.

Description

technical field [0001] The invention relates to a single-layer covering electric welding machine cable material and a preparation method thereof, belonging to the technical field of cables. Background technique [0002] With the rapid development of the economy, wires and cables have been widely used in various industries and fields. At the same time, with the increasing number of cable manufacturers and increasingly fierce competition, how to reduce the production cost of cables on the basis of ensuring quality has become an important issue for various cable manufacturers. Manufacturers are most concerned about research and development topics. The electric welding machine cable can choose double-layer covering or single-layer covering. The advantage of single-layer covering is that it saves the process, but there is a technical problem that the covering layer needs to take into account the dual characteristics of insulation and sheath. The single-layer covering layer can pa...

Problems solved by technology

The electric welding machine cable can choose double-layer covering or single-layer covering. The advantage of single-layer covering is that it saves the process, but there is a technical problem that the covering layer needs to take into account the dual characteristics of insulation and sheath. The single-layer covering layer can pass the voltage test when it meets the insulation and electrical properties. , wear-resistant, oil-resistant, soft, and flame-retardant, it is also necessary to consider whether there is a market competitive advantage in the price of materials. It is difficult to meet the above needs with the background technology
