Abstract

The invention discloses a glazed flame-retardant PVC material for a cable sheath and a preparation method thereof. The material comprises the following components in parts by weight: 100-150 parts ofPVC, 30-50 parts of a glaze, 4-5 parts of a stabilizer, 45-60 parts of dioctyl phthalate, 0.5-1.0 parts of a lubricant, and 5-10 parts of zinc borate. The preparation method comprises the following steps of: S1. preparation of the glaze, S2. kneading of the glazed flame-retardant PVC material, and S3. plasticized granulation of the glazed flame-retardant PVC material. The glazed flame-retardant PVC material for the cable sheath provided by the invention has A-class flame-retardant property, can effectively prevent the flame-retarding and dripping of the wires and cables, has the heat insulation effect, can protect an insulating layer from thermal breakdown, and ensures that the material can be powered on at a fire site for a period of time.

Description

technical field [0001] The invention relates to the field of wire and cable sheath materials, in particular to an imitation glaze flame-retardant PVC material for cable sheaths 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 fl...
