Abstract

The invention discloses a high impact polystyrene sheath material for power cords and a preparation method thereof. The sheath material is prepared from the following raw materials in part by weight: 45-65 parts of high impact polystyrene, 20-30 parts of polypropylene, 10-15 parts of ethylene propylene diene monomer, 5-10 parts of styrene-isoprene-styrene block copolymer, 4-8 parts of paraffin oil, 3-6 parts of ethylene bis oleamide, 1-2 parts of isopropyl tri(dioctyl pyrophosphate acyloxy) titanate, 10-15 parts of talc powder, 3-5 parts of nano beryllia, 1-2 parts of zinc stearate, 4-6 parts of calcium hydroxide, 2-5 parts of low molecular polybutylene, 15-25 parts of carbon black N550, 2-3 parts of di-tert-butyl peroxide, 1.5-2.5 parts of trihydroxypropane trimethylacrylate, 10-15 parts of acetyl triethyl citrate, 5-10 parts of diphenyl-isooctyl phosphite and 15-20 parts of aid. The sheath material is good in electric insulating property, high in mechanical strength, good in toughness and high in impact resistance, has the characteristics of excellent heat, corrosion, oil and water resistance and the like and is durable, so that the sheath material has a wide application prospect.

Description

technical field [0001] The invention relates to a power cord sheathing material and a preparation method thereof, in particular to a high-impact polystyrene sheathing material for power cords and a preparation method thereof. Background technique [0002] The power cord is a wire that transmits current, and the sheath is an indispensable structural part of the power cord, which plays the role of protective insulation, ensures the safety of the power cord, isolates the conductor from water, air and other media, and avoids leakage. At present, the power cord sheath material on the market has the disadvantage of poor impact resistance, and it is easy to cause cracks when encountering high impact external force during use, thus affecting the normal operation of the power cord. Therefore, there is an urgent need to develop a high-impact sheathing material for power cords. Contents of the invention [0003] The purpose of the present invention is to provide a high-impact polyst...
