Highly-flame-retardant scratch-resistant frosting TPE sheathing material

Abstract

The invention discloses a highly-flame-retardant scratch-resistant frosting TPE sheathing material. The highly-flame-retardant scratch-resistant frosting TPE sheathing material comprises the following components in percentage by weight: 15 to 35 percent of styrene block copolymer, 6 to 15 percent of modified polyphenyl ether, 7 to 15 percent of thermoplastic dynamic vulcanized rubber, 5 to 18 percent of polyolefin, 8 to 15 percent of extending oil, 3 to 10 percent of plasticizer, 20 to 35 percent of flame retardant, 0.8 to 3 percent of lubricant and 0.2 to 0.5 percent of UV stabilizer. As compared with the prior art, reasonable proportions of components are obtained through elaborate design and repetitive tests, finally the highly-flame-retardant scratch-resistant frosting TPE sheathing material is obtained, the surface of the outer sheath produced by using the material disclosed by the invention is wear-resistant, the scratch resistance is excellent, scratches are not easily produced on the surface, the maximum oxygen index can reach to 40, the flame-retardant effect is very good, and the material further has the advantages of good frosting hand feeling, high oil resistance, low surface gloss, high tensile strength, good impact resistance and low temperature resistance, good processing performance and the like.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a TPE sheathing material with a high flame-retardant, scratch-resistant and frosted feel. Background technique

[0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. Cables are susceptible to scratches during laying and moving. Especially the special optical cables used in 3G communication projects and fiber-to-the-home projects are mostly used in mobile communication base stations or indoors, and the materials used for the sheath of optical cables are required to be environmentally friendly, flame-retardant, low-smoke and non-toxic; The optical cable is used indoors, the space is small, the movement is frequent, and it is easy to be scratched. It is required that the surface of...
