Problems solved by technology

[0002] At present, there is still a considerable share of domestic wire and cable PVC insulation products. Conventional PVC wires and cables are quite polluted, and a large amount of harmful substances such as dioxin and lead will be produced during manufacture, use and disposal.
When PVC material is burned, it will produce a lot of smoke and harmful HCl gas, which will cause certain harm to human health. After burning and burying, it will cause soil and water pollution

Abstract

The invention discloses a low-smoke, zero-halogen and environment-friendly flame-retardant PVC (polyvinyl chloride) composite. The composite is prepared from components of raw materials in parts by weight as follows: 100 parts of PVC, 45-55 parts of DOP (dioctyl phthalate), 25-35 parts of calcium carbonate, 75-85 parts of hydromagnesite powder and huntite powder, 3-5 parts of antimonous oxide, 6-8 parts of a heat stabilizer, 1.4-1.8 parts of a lubricant and 0.4-0.6 parts of a metal deactivator. The prepared low-smoke, zero-halogen and environment-friendly flame-retardant PVC composite has an excellent flame retardant function and cannot affect the mechanical strength of plastics.

Description

technical field [0001] The invention belongs to the technical field of PVC materials, and in particular relates to a low-smoke, halogen-free and environment-friendly PVC flame-retardant composite material. Background technique [0002] At present, domestic wire and cable PVC insulation products still have a considerable share. Conventional PVC wires and cables are quite polluted, and a large amount of harmful substances such as dioxin and lead will be produced during manufacture, use and disposal. When PVC material is burned, it will produce a lot of smoke and harmful HCl gas, which will cause certain harm to human health. After burning and burying, it will cause soil and water pollution. Therefore, how to design flame-retardant wire and cable products that meet low smoke, low toxicity, and low corrosion has become an urgent task for the whole society. Contents of the invention [0003] The purpose of the present invention is to solve the defects and deficiencies in the a...
