Problems solved by technology

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of acetylene carbon black or acetylene carbon black to polyolefin substrates to achieve flame retardancy. Effect, however, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of cable materials

Abstract

The invention discloses a flame-retardant and weather-resistant PVC cable material, which comprises the following materials (by weight): 60-70 parts of polyvinyl chloride; 10-14 parts of fluororubber;12-16 parts of ABS / PC alloy; 20-25 parts of a plasticizer; 6-10 parts of a stabilizer; 6-8 parts of a filler; 3-5 parts of an antioxidant; 1-3 parts of a flame retardant; and 0.5-1 part of KH-560. Byoptimizing chemical composition of the flame-retardant and weather-resistant PVC cable material, the internal structure of PVC plastic is improved at the microcosmic level. The product has excellentweather resistance and flame-retardant property.

Description

technical field [0001] The invention relates to a plastic, in particular to a flame-retardant and weather-resistant PVC cable material. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. However, at present, the market The cable material is not resistant to high temperature and aging, and the material turns yellow and becomes brittle after the aging test. There are more and more fires caused by aging wires. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At p...
