High-temperature-resistant flame-retardant cable material and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant flame-retardant cable material and a preparation method thereof. The high-temperature-resistant flame-retardant cable material comprises, by weight, 60-80 parts of phenolic resin, 50-100 parts of polyvinyl chloride, 20-40 parts of polyacrylate rubber, 1-3 parts of zinc dimethyldithiocarbamate, 3-6 parts of dibasic lead phosphite, 10-30 parts of antimonous oxide, 5-10 parts of aluminium hydroxide, 5-15 parts of silicon dioxide, 5-30 parts of titanium dioxide, 5-10 parts of glass fibers, 15-30 parts of dioctyl phthalate, 2-6 parts of chlorinated paraffin and 50-80 parts of filler. The high-temperature-resistant flame-retardant cable material has the advantages that on the premise of guaranteeing excellent flexibility and insulativity, combustion of internal polymers of the cable material is inhibited effectively, so that flame retardance of the cable material is improved; the high-temperature-resistant flame-retardant cable material is highly resistant to high temperature, and safety performance is improved while production cost is reduced; the preparation method is simple and easily available to raw materials.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high temperature resistant flame retardant cable material and a preparation method thereof. Background technique [0002] Cables mainly refer to wires and cables, which are mainly used in power systems, information transmission systems, mechanical equipment, and instrumentation systems. The demand and usage in daily life are large, and its main display form in daily life is to be placed between two utility poles, such as overhead wires, local telephone cables, TV cables, electronic cables, power cables, etc. With the development of economy and society, cables have also been widely used in fields such as aviation, automobiles and oil exploration. Cable material is an important part of the cable, which not only protects the internal material from the external environment, but also ensures that the cable can maintain normal operating functions. Therefore, when preparing ...

Problems solved by technology

Among them, the fire phenomenon caused by the poor flame retardancy or high temperature resistance of the cable material accounts for the vast majority. Since the cable will generate a lot of heat during use, if the cable material has poor high temperature resistance and flame resistance, it will be in Burning will occur inside the cable under high temperature for a long time, which not only affects the normal work and operation, but also causes fire. Therefore, the performance of the cable material will directly endanger the life safety of users and cause property damage. huge loss

However, today's cable materials are generally poor in fire resistance, heat resistance and flame retardancy. Although some pay attention to the importance of flame retardancy of cable materials, they ignore the changes in other properties while improving flame retardancy, resulting in The overall effect of the cable is not obvious
