Abstract

The invention discloses a moisture-resistant and water-resistant high-density polyethylene cable material and a preparation method thereof. The cable material is prepared from raw materials in parts by weight as follows: 69-81 parts of high-density polyethylene, 26-42 parts of polyphenylene oxide, 18-34 parts of polyphenylquinoxaline, 15-30 parts of fluorosilicon resin, 15-25 parts of magnesite, 15-20 parts of 4,5-epoxyte-trahydrophthalic acid di-(2-ethylhexyl)ester, 20-30 parts of volcaniclastic rock, 10-15 parts of barium residues, 5-8 parts of oleamide, 4-6 parts of zinc oxide and 10-15 parts of pyrolytic waste rubber powder. The moisture-resistant, water-resistant and high-density polyethylene cable material combines advantages of high-density polyethylene, polyphenylquinoxaline and the like, and meanwhile, raw materials such as 3-isocyanatopropyltriethoxysilane, phenyl salicylate and the like are added, so that the water absorption of the cable material is greatly reduced, and the cable material has excellent moisture resistance and water resistance, also has good heat resistance, weather resistance and corrosion resistance and can be used in a moisture or soaking environment for a long time.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a moisture-resistant and water-resistant high-density polyethylene cable material and a preparation method thereof. Background technique [0002] Polyethylene, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. It is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ~ -70 ° C), good chemical stability, and can resist most acid and alkali erosion (not resistant to oxidizing properties. acid). It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation, and can be widely used in the production of cable products. With the rapid development of the cable industry, there are increasingly higher requirements for the performance of polyethylene cables. However, the existing polyethylene cable materials...
