Abstract

The invention relates to an anti-aging cable insulation wrapper, which is prepared from the following raw material components in parts by weight: 60-65 parts of butadiene styrene rubber, 9-10 parts of zinc oxide, 5-8 parts of a protective agent mixture, 2-4 parts of an accelerant mixture and 15-20 parts of talcum powder. According to the insulation wrapper, by adjusting the raw material formula, the raw material cost is reduced, the adjusted insulation wrapper for cables achieves the safe using requirement and meets the requirement of the fields in the market, the strength of extension of the insulation wrapper before aging achieves 9N / mm<2> and the elongation of the insulation wrapper before aging can be 400%.

Description

technical field [0001] The invention belongs to the field of electric wire and cable processing, and relates to cable insulating rubber skins, in particular to an aging-resistant cable insulating skin. Background technique [0002] With the advancement of technology, cable insulation is used in all walks of life, and its demand is increasing. EPDM rubber has become an insulating material widely used in the wire and cable industry because of its many advantages. Its cost is high, and its production and use are subject to certain restrictions. At present, the production of cable insulation has gradually eliminated this raw material, and styrene-butadiene rubber has begun to be used. [0003] Styrene butadiene rubber is the most widely used synthetic rubber, including emulsion polystyrene butadiene rubber and solution polystyrene butadiene rubber. Styrene-butadiene raw rubber is a light yellow-brown elastic solid. The density increases with the increase of styrene content. It ...
