High-flame retardation polyethylene cable material and preparation method thereof

Abstract

The invention discloses a high-flame retardation polyethylene cable material. The high-flame retardation polyethylene cable material is mainly prepared from, by mass, 110-124 parts of polyethylene, 16-21 parts of chlorinated paraffin, 4-10 parts of sulfur, 6-11 parts of epoxidized soybean oil, 6-12 parts of diatomite, 5-11 parts of zinc borate, 8-12 parts of potter's clay, 2-6 parts of dicapryl phthalate, 3-6 parts of white carbon black, 10-16 parts of aluminum hydroxide, 2-4 parts of stearic acid and 0.4-0.8 parts of lauryl thiodipropionate. The cable material prepared in the invention has the advantages of protruding flame retardation performance, protruding mechanical performances, small smoke amount and high safety.

Description

technical field

[0001] The invention relates to the field of cable materials, in particular to a high flame-retardant polyethylene cable material and a preparation method thereof. Background technique

[0002] With the progress of society and the development of science and technology, people's demand for low-smoke, halogen-free and flame-retardant materials is increasing. In many large public places, in order to avoid secondary disasters caused by cable fires (a large amount of smoke and acid gas are produced when cables burn). For wires and cables specially used to transmit electric energy and communication signals, it is not only required to have flame retardant properties such as preventing flame spread when the cable and the surrounding environment catch fire, and can maintain the cable to continue to transmit electric energy and communication signals. It should have low smoke generation, low corrosiveness of the generated gas, and facilitate the safe evacuation of the ...
