Problems solved by technology

At present, domestic acid and alkali-resistant cables are basically fluoroplastic cables and silicone rubber cables. Fluoroplastics have excellent acid and alkali resistance, but they have extremely high requirements for processing equipment and production technology, and they are easy to crack if they are slightly improper. Fluoroplastics are expensive, and it is difficult to produce large cross-section cables; silicone rubber cables have excellent acid and alkali resistance. Compared with fluoroplastics, they have lower requirements for processing equipment and production technology, and are also more expensive Low, wide coverage of specifications, but the silicone rubber cable has a dense flaw, that is, extremely poor mechanical properties, poor resistance to external force damage in some frequent bending occasions, and low service life

Abstract

The invention discloses two environmental low temperature resistant and acid and alkali resistant cable sheath rubbers, and a preparation method thereof. The environmental low temperature resistant and acid and alkali resistant cable sheath rubbers are mainly prepared from the following components in parts by weight: 100 parts of chlorinated polyethylene rubber, 5-10 parts of high-activity magnesium oxide, 3-5 parts of environmental stabilizer, 4-6 parts of microcrystalline wax, 70-100 parts of acid and alkali resistant filler, 5-10 parts of antimonous oxide, 3-5 parts of DCP (dicumyl peroxide), 3-5 parts of TAIC (triallyl isocyanurate), 1-2 parts of RD (2,2,4-trimethyl-1,2-dihydrogen quinoline polymer),15-20 parts of DOS (dioctyl sebacate), 15-25 parts of carbon black, 10-20 parts of nano clay and 3-5 parts of hansa yellow or fast red. The environmental low temperature resistant and acid and alkali resistant cable sheath rubbers can meet the acid and alkali resistant requirements of the rubber sheath cables, and also have the environmental performance and the low temperature resistance.

Description

[0001] technical field [0002] The invention relates to a preparation method of a cable sheath, in particular to a preparation method of two environment-friendly low temperature resistant acid and alkali resistant cable sheath rubbers. Background technique [0003] At present, in some special fields, such as sewage treatment plants, thermal power plants, chemical plants, smelting plants and other places, due to the special environment, the cables used in these places need to have better acid and alkali corrosion resistance . At present, domestic acid and alkali-resistant cables are basically fluoroplastic cables and silicone rubber cables. Fluoroplastics have excellent acid and alkali resistance, but they have extremely high requirements for processing equipment and production technology, and they are easy to crack if they are slightly improper. Fluoroplastics are expensive, and it is difficult to produce large cross-section cables; silicone rubber cables have excellent ac...
