Embodiment 1

[0034] A light-colored insulating and wear-resistant styrene-butadiene rubber composition for water-cooled cable sheath, its components and parts by weight are as shown in Table 1, and prepared according to the following preparation method:

[0035] (1) The internal mixer is cooled by water, and the temperature of the internal mixer is controlled not to exceed 60 °C. First, styrene-butadiene rubber, natural rubber, antioxidant and protective wax are mixed for 1 to 2 minutes, and then zinc oxide and stearin are added. Acid, silica, silicon micropowder, silane coupling agent and naphthenic oil are mixed for 4 to 6 minutes; finally, mica powder is added and mixed for 2 to 4 minutes; the mixer is turned off and cooled, and the mixing is continued until the temperature of the mixer rises. When it reaches 140°C, remove the glue, move it to an open rubber mixing machine for thin film discharge, and cool it to room temperature (20-30°C);

[0036] (2), put the mixture obtained in step ...

Abstract

The invention discloses a light-color insulating wear-resistant styrene-butadiene rubber composition for a water-cooled cable sheath. The light-color insulating wear-resistant styrene-butadiene rubber composition comprises the following components in parts by weight: 70-100 parts of styrene-butadiene rubber, 0-30 parts of natural rubber, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 40-60 parts of white carbon black, 5-15 parts of silica powder, 40-60 parts of mica powder, 2-4 parts of a silane coupling agent, 5-15 parts of naphthenic oil, 2-4 parts of an anti-aging agent, 1-3 parts of protective wax, 0-1 part of sulfur and 3-6 parts of an accelerant. The butadiene styrene rubber product prepared by the invention not only has excellent physical and mechanical properties, but also has insulation, wear resistance and electric breakdown resistance, meets the requirements of main engine plants on the product, and has very high economic value.

Description

technical field [0001] The invention belongs to the field of rubber, and relates to an insulating and wear-resistant rubber formulation applied to rubber products, in particular to a light-colored insulating and wear-resistant styrene-butadiene rubber composition for water-cooled cable sheathing and a preparation method thereof. Background technique [0002] EPDM rubber is a copolymer composed of ethylene, propylene and a small amount of non-conjugated diene. Its main chain is composed of chemically stable saturated hydrocarbons and only contains unsaturated double bonds in the side chain, so it is heat-resistant, Excellent weather resistance, widely used in automotive parts, waterproof materials for construction, wire and cable jackets, heat-resistant hoses and other fields. The water-cooled cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable's power supply, isolating the ...
