Abstract

The invention relates to the technical field of cable materials, and provides a flexible high-temperature-resistant transmission signal cable. The cable comprises a center conductor and a protective sleeve wrapping the center conductor. The protective sleeve comprises the following components in parts by weight: 40-60 parts of nitrile rubber, 25-30 parts of fluorinated silicone rubber, 2-4 parts of benzoyl peroxide, 35-45 parts of polyvinyl butyral, 3-8 parts of coumarone indene resin, 10-15 parts of modified vermiculite, 10-20 parts of a flame retardant, 0.5-1 part of cyanogen-containing silicone oil, 1-3 parts of an ultraviolet light absorber, 3-6 parts of a heat stabilizer and 8-14 parts of glass fibers. The invention further provides a preparation method of the flexible high-temperature-resistant transmission signal cable. According to the technical scheme, the problem that a cable protection sleeve is poorer in flexibility and high temperature resistance is solved.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a soft, high-temperature-resistant transmission signal cable and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, it provides a huge market prospect for the development of the cable industry. At present, the cable industry is one of the largest industries in my country. And with the continuous development of my country's electric power, communications, rail transit and other industries, there will be more demand for cables. [0003] For cables, in addition to the central conductor, the protective sheath also plays a vital role in the performance of the cable. Because the working temperature of the transmission signal cable is high, if the temperature resistance of the protective cover is not good, it will become hotter and hotter if it cannot be used for a long time, and even cause safety problems such as fir...
