Abstract

Electric sealed waterproof electro-insulating rubber dough and its preparation method. The preparation method comprises the following steps: uniformly stirring 100 parts by weight of natural rubber particles and 58-60 parts by weight of channel black, adding 6-6.5 parts by weight of zinc oxide, 3-3.5 parts by weight of sulphur, 3.5-4 parts by weight of stearic acid, 0.4-0.6 part by weight of an accelerator DM and 1.3-1.5 parts by weight of an accelerator TMTD and uniformly stirring, adding 30 parts by weight of liquid polyisobutylene, 0.8-1 part by weight of a rubber antioxidant RD, 10-10.5 parts by weight of rosin and 10 parts by weight of alpha-pinene resin and uniformly stirring, heating to 100 DEG C and keeping for 40-60 min, cooling to room temperature, and sealing and packaging. By the use of the rubber dough, electric line contacts are effectively sealed and electro-insulated. The product has air isolation, water isolation and insulation effects, and protects line contacts exposed to the air or underground line contacts so as to prevent line contacts from oxidation and electric leakage and overlarge contact resistance and guarantee service life of electric lines.

Description

technical field [0001] The invention belongs to the field of cable joint insulation and sealing, and in particular relates to a power sealing waterproof insulating rubber clay and a preparation method thereof. Background technique [0002] With the increase of urban planning and construction, urban distribution network transformation, overhead insulated wires are widely used, and the laying of underground cables has increased in large quantities. Underground power line joints often appear in accident repairs such as power company construction or cable digging. Nowadays, power lines generally have insulation skins. After power line joints appear, the joints are exposed or wrapped with tape, which is very easy to Oxidation, leakage occurs, affecting line safety, or causing excessive contact resistance, resulting in shortened service life of power lines. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of pow...
