Embodiment Construction

[0042] Put the 18% natural rubber, 12% styrene-butadiene rubber, 7.95% butadiene rubber, 8.5% chloroprene rubber, and 10% tread regenerated rubber into the open rubber mixer by weight percentage For refining, adjust the roller distance of the rubber mixing machine to about 1.5mm for rubber breaking; adjust the roller distance of the rubber mixing machine to 0.5mm, and control the roller temperature at about 45°C. Pass the broken film through the gap between the rollers to let the rubber material Drop directly into the receiving tray; then adjust the roller distance of the rubber mixer to the required thickness of the next piece to cut the next piece to form a sheet of plasticized rubber; check the plasticity of the plasticized rubber to be 0.34±0.005; plasticized rubber After 24 hours of parking, kneading is carried out.

[0043] Mixing goes through one-stage mixing, two-stage mixing, and three-stage mixing. In the first stage of mixing, 70% plastic rubber and 80% of 9.5% high...

Abstract

The invention relates to an enhanced water-cooled cable sleeve rubber material and a manufacturing technology thereof. The material consists of 18wt% of natural rubber, 12wt% of butylbenzene rubber, 7.95wt% of butadiene rubber, 8.5wt% of chloroprene rubber, 10wt% of peel reclaim, 9.5wt% of high abrasion carbon black, 15wt% of kaolin, 9.5wt% of light calcium carbonate, 2wt% of zinc oxide, 0.6wt% of stearic acid, 0.1wt% of paraffin, 0.4wt% of accelerant M, 0.25wt% of accelerant TMTD, 0.4wt% of accelerant DM, 1wt% of anti-aging agent, 0.8wt% of sulfur, 3wt% of pine tar oil and 1wt% of engine oil; through the manufacturing technology of plastication, one-section mixing, two-section mixing and three-section mixing, the water-cooled cable sleeve rubber material with comprehensive performances of high pressure resistance, high temperature resistance, abrasion resistance, shock resistance, thermal radiation resistance, aging resistance and the like is obtained; a water-cooled cable protective sleeve manufactured from the material can improve the safety protection coefficient of industrial electric heating equipment heavy current busbars, and the service life of the water-cooled cable protective sleeve is also prolonged exponentially.

Description

technical field [0001] The invention relates to a rubber material and a production process, in particular to a rubber material and a process for producing a water-cooled cable sleeve for protecting a large current busbar. Background technique [0002] Water-cooled cable casing is a synthetic rubber tube for external protection of high-current busbars of industrial electric heating equipment. It is formed by vulcanizing an inner rubber layer, a multi-layer cloth winding layer, an outer rubber layer and a thermal protection layer. Since the bushing has been operating under high pressure, high temperature, and impact for a long time, it must have good high pressure resistance, high temperature resistance, wear resistance, impact resistance, heat radiation resistance, and aging resistance. The main rubber as the outer rubber layer and the inner rubber layer plays a vital role in the quality of the above performance. The existing rubber materials used for water-cooled cable bush...
