Problems solved by technology

However, the flame retardant performance of PVC wires and cables has always troubled everyone. At present, the flame retardant materials of wires and cables mostly contain halogen. The secondary damage caused by poisoning and dripping is extremely important. At present, domestic research on the flame retardancy of wire and cable sheathing materials mainly focuses on organic phosphorus nitrogen and inorganic hydrates, but the current research results still have flame retardancy and heat insulation. The existing problems such as poor temperature effect, so it is necessary to find a cable sheath material and its preparation method that can solve the above problems

Abstract

The invention discloses a PVC (polyvinyl chloride) material for cable shells. The PVC material is prepared from the following components in parts by weight: 100-150 parts of PVC granules, 0.3-0.6 parts of a lubricant, 20-50 parts of a modified plasticizer, 0.5-5 parts of an antioxidant, 1-10 parts of a flame retardant, 15-50 parts of filler, 20-40 parts of foaming filling granules, 10-20 parts of asbestos granules and 15-30 parts of glaze liquid. The PVC material for cable shells has an efficient flame-retardant function and is good in thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a PVC material used for cable shells and a preparation method thereof. Background technique [0002] Since the advent of wire and cable products, they have brought great convenience and improvement to human life and work. PVC cables have long occupied an important position in wire and cable insulation and protection materials because of their low price and excellent performance. However, the flame retardant performance of PVC wires and cables has always troubled everyone. At present, the flame retardant materials of wires and cables mostly contain halogen. The secondary damage caused by poisoning and dripping is extremely important. At present, domestic research on the flame retardancy of wire and cable sheathing materials mainly focuses on organic phosphorus nitrogen and inorganic hydrates, but the current research results still have flame retardancy and heat insulat...
