Matte oil-resistant elastomer cable material

Abstract

The invention provides a matte oil-resistant elastomer cable material which is prepared from the following component raw materials in parts by weight: 20-40 parts of linear low density polyethylene, 10-20 parts of high density polyethylene, 20-40 parts of polyethylene and octylene elastomer, 10-20 parts of ethylene-vinyl acetate copolymer, 10-15 parts of a PVC (Polyvinyl Chloride) paste resin, 2-3 parts of dilauryl thiodipropionate, 1-2 part(s) of di-n-butyltin laurate, 20-25 parts of aluminum hypophosphite, 1-2 part(s) of melamine pyrophosphate, 10-15 parts of magnesium hydroxide, 5-10 parts of zinc borate, 1-3 parts of bi(3,5-tert-butyl-4-hydroxyphenyl) thioether, 2-4 parts of polyethylene wax, 1-2 part(s) of polytetrafluoroethylene, 5-10 parts of modified filler, 3-5 parts of vinyl tri(2-methoxyethoxy) silane, 1-2 part(s) of N-cupric-ion Inhibitor MDA-5 and 1-3 part(s) of dibenzoyl peroxide. Compared with a common low-smoke halogen-free polyolefin cable material, the matte oil-resistant elastomer cable material has the advantages that a temperature resistance grade of the product is improved, the mechanical property is improved, and a problem that the common low-smoke halogen-free polyolefin cable material is easily cracked is solved.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a matte oil-resistant elastomer cable material. Background technique [0002] Wire and cable have the function of power transmission and information transmission, and play an important role in people's life and production. Designing and preparing low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials. It has been studied that the cable material material with good flame retardant performance, e...
