Problems solved by technology

However, there are small molecular plasticizers that are easy to migrate in the ethylene-propylene rubber insulating material, and will precipitate after a period of use, while macromolecular plasticizers have poor compatibility with the ethylene-propylene rubber insulating material, which cannot be significantly improved. Improve its cold resistance

Abstract

The invention discloses cold-resistant and fracture-resistant cable sheath materials and a preparation method thereof. The cold-resistant and fracture-resistant cable sheath materials comprise, by weight, 30-50 parts of ethylene propylene monomer, 40-60 parts of butyl rubber, 10-15 parts of iso-Octyl methacrylate, 2-6 parts of magnesium hydroxide, 1-5 parts of antimonous oxide, 12-16 parts of histamine phosphate, 2-8 parts of zinc salicylate, 10-16 parts of ethylenediamine tetramethylene phosphonic acid, 7-13 parts of 3-aminoethy trimethoxy silane, 6-15 parts of hexamethyl disilazane, 3-8 parts of 5-hydroxytryptamine, 4-10 parts of catechol borane, 5-12 parts of cis-3-Hexenyl isobutyrate and 2-9 parts of undecanoic delta-lactone. The cable sheath materials have excellent facture resistance in a cold environment of minus 60 DEG C.

Description

technical field [0001] The invention belongs to the field of cable sheath materials, and in particular relates to a cold-resistant and fracture-resistant cable sheath material and a preparation method thereof. Background technique [0002] In the cable industry, ordinary ethylene-propylene rubber insulating materials are a common choice, but in some harsh environments with low temperature or relatively large temperature difference conditions, ordinary ethylene-propylene rubber insulating materials show poor stress resistance, easy cracking, Problems such as poor softness and mechanical strength greatly limit its wide application in northern my country and other regions. At present, some studies have used the method of adding plasticizers to achieve the purpose of improving its cold resistance. However, there are small molecular plasticizers that are easy to migrate in the ethylene-propylene rubber insulating material, and will precipitate after a period of use, while macromo...
