Ceramic silicone rubber cable material and preparation method thereof

Abstract

The invention provides a ceramic silicone rubber cable material. The cable material is prepared by using the following raw materials, by weight, 80-90 parts of silicone rubber, 10-20 parts of natural rubber, 20-30 parts of mineral silicate, 10-15 parts of diantimony trioxide, 10-20 parts of ammonium polyphosphate, 4-6 parts of zinc oxide, 1-2 parts of an antioxidant DTPD, 20-30 parts of spraying carbon black, 10-20 parts of light calcium carbonate, 14-16 parts of aluminum hypophosphite, 1-2 parts of calcium stearate, 1-2 parts of pentaerythritol, 1-2 parts of talcum powder, and 12-14 parts of a modification filler. The cable material has the advantages of excellent flame retardancy, and very small smoke amount and no generation of toxic gases or corrosive gases during combustion, and forms a hard shell after the combustion, and the hard shell does not shed and protects a combusted cable from damages to guarantee normal power transmission.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a vitrified silicone rubber cable material and a preparation method thereof. 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 ceramic silicon...

Problems solved by technology

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