Problems solved by technology

It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance and chemical corrosion resistance. It can be used for a long time at 80-100 °C and has a certain flame retardancy. However, the disadvantage is that the storage stability is poor. Therefore, using neoprene as a cable sheath material can ensure that it has strong heat resistance, aging resistance, oil resistance, corrosion resistance, etc., and by adding some modified fillers. Improving its storage stability further improves the performance of the cable sheathing material

Abstract

The invention discloses a corrosion-resistant cable sheath material which is prepared from the following raw materials in parts by weight: 100-102 parts of neoprene CR121, 3-4 parts of aluminum oxide, 4-6 parts of diisobutyl phthalate, 3-4 parts of acetyl triethyl citrate, 1-2 parts of dibasic lead phosphite, 1-2 parts of acetylacetone titanium, 1-2 parts of ethylene glycol dimethacrylate, 2-3 parts of ammonium dihydrogen phosphate, 3-5 parts of ethylene bis stearamide, 25-30 parts of silica powder, 18-24 parts of modified filler, 1-2 parts of bis(P,P-bis-ethylhexyl diphosphato)ethanediolato titanate, 1-2 parts of anti-aging agent ippd, 3-4 parts of diethanolamine and 0.8-1 part of lead oxide. The modified filler disclosed by the invention has the advantages of favorable dispersity and low surface tension, further enhances the tensile strength and stress at definite elongation of the cable material, lowers the heat generation and permanent compression set, can postpone the aging rate of the cable material, can resist acid/alkali corrosion, and lowers the production cost.

Description

technical field [0001] The invention mainly relates to a cable sheathing material, in particular to a corrosion-resistant cable sheathing material. Background technique [0002] Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. It has high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance and chemical corrosion resistance. It can be used for a long time at 80-100 °C and has a certain flame retardancy. However, the disadvantage is that the storage stability is poor. Therefore, using neoprene as a cable sheath material can ensure that it has strong heat resistance, aging resistance, oil resistance, corrosion resistance, etc., and by adding some modified fillers. Improving its storage stability further improves the performance of the cable sheat...
