Abstract

The invention discloses a glazed flame-retardant PVC wire duct and a preparation method thereof. The PVC wire duct comprises the following materials in parts by weight: 100-140 parts of PVC, 30-50 parts of a glaze, 50-75 parts of calcium carbonate, 4-8 parts of a stabilizer, 0.2-0.4 parts of stearic acid, 0.4-0.6 parts of PE wax, and 5-8 parts of CPE. The preparation method comprises the followingsteps 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 wire duct. The glazed flame-retardant PVC wire duct has A-class flame-retardant property, can effectively prevent the flame-retarding and dripping of wire ducts, has good flame retardation effect, prevents short circuit due to cable combustion in the wire duct, reduces property loss, and gains time for rescuing.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an imitation glaze flame-retardant PVC trunking and a preparation method thereof. Background technique [0002] Since the advent of building firewall products, it has brought great convenience and improvement to human life and work. Among them, PVC trunking is mainly used for internal wiring of electrical equipment. Because of its low price and excellent performance, it has long occupied an important role in building trunking materials. status. The use of PVC trunking can not only provide mechanical protection and electrical protection for the wires laid in it, but also facilitate wiring, neat wiring, reliable installation, and easy search, maintenance and replacement of lines. However, the flame retardant performance of PVC trunking troubles everyone. In order to improve the flame retardancy of PVC trunking, flame retardant materials are often added to PVC, but the flame retar...
