AI Technical Summary

Problems solved by technology

[0005] However, the existing cable sheaths still have the following disadvantages: (1) The amount of filled inorganic titanium dioxide or organic anti-UV additives is usually large, which is likely to cause the deterioration of the mechanical properties and flame retardancy of the material, and it is easy to precipitate and cause Blooming on the surface of the material is formed, and a high proportion of the added amount also affects the color; (2) The wear-resistant agent currently used is ceramic powder / silicon carbide particles, which has poor compatibility with the matrix material, and the flexibility of the cable is poor and It should not be folded, and the antibacterial agent mostly uses nano-silver antibacterial agent, and the silver ions in it will be released continuously, which will pollute the environment and endanger the health of users

Description

technical field [0001] The invention belongs to the technical field of wire and cable materials, and in particular relates to an anti-UV, wear-resistant and anti-mold cable material and a preparation process thereof. Background technique [0002] A wire and cable is made of one or more mutually insulated conductors and an outer insulation layer, which transmits power or information from one place to another. The missing intermediate structure can ensure the safety of the cable, isolate the copper wire from water, air and other media and avoid leakage. With the development of science and technology, the use of various intelligent equipment has led to the rapid development of the wire industry. In addition to requiring the cable sheath to meet the basic mechanical properties, insulation properties and flame retardant properties, it is also required to have good resistance UV discoloration, wear resistance, mildew resistance, etc., especially for cables with light colors. In ...
