Problems solved by technology

With the increase of chlorine content, the compatibility of plasticizer, low temperature resistance, compression set resistance, thermal aging performance, etc. decrease, and the water resistance is poor. When the temperature is relatively low, the material itself is relatively hard, low in elasticity and brittle. Large, low tear resistance

Abstract

The invention discloses an anticorrosive flame-resistant cable sheath insulating material and a preparation method thereof. The anticorrosive flame-resistant cable sheath insulating material comprises the following materials in parts by weight: 95-105 parts of chloroprene rubber CR121, 15-20 parts of chlorosulfonated polyethylene rubber CSM 2305, 15-25 parts of semi-reinforcing carbon black N774, 2-3 parts of magnesium oxide, 1-2 parts of aluminate coupling agent DL-411, 30-35 parts of barite powder, 1-2 parts of anti-ageing agent MB, 1-2 parts of di-(dioctyloxypyrophosphate) ethylene titanate, 5-8 parts of polyamide wax micro powder, 1-2 parts of accelerator DM, 0.8-1 part of accelerator TMTD (Tetramethyl Thiuram Disulfide), 15-25 parts of high-abrasion carbon black N330, 1-3 parts of adipic propylene glycol polyester, 2-4 parts of hydrated zinc borate, 4-6 parts of glass powder, 0.8-1 part of zinc oxide, 2-3 parts of modified bentonite and 4-6 parts of 4,4'-benzenesulfonyl oxodihydrazide. The anticorrosive flame-resistant cable sheath insulating material produced by the preparation method disclosed by the invention is excellent in physical properties, stable in dimension and low in shrinking percentage; moreover, the prompting strength, tearing strength and resilience force performance of the product can be greatly improved, so that the performance of the common silicon rubber is achieved under the normal temperature; and a hard shell is formed through erosion of high-temperature flame, and the eroded object is protected from being damaged.

Description

technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to an anti-corrosion and flame-retardant cable sheath insulation material and a preparation method thereof. Background technique [0002] Fireproof (fire-resistant) cable refers to a type of cable that can ensure the integrity of the line in the event of a fire; this kind of cable can ensure that the cable can continue to provide power and transmit various signals normally for a long time in the event of a fire, so that Provide protection for fire control and lifesaving; especially for theaters, subways, airports, nuclear power plants and other crowded public places or important places. According to the different refractory materials used, the existing fire-resistant cables are divided into mica tape fire-resistant cables and mineral insulated fire-resistant cables. These two types of fire-resistant cables can both meet Class A (test temperature 95...
