Anti-deformation heat preservation compound ethylene propylene diene monomer cable material and preparation method thereof

Abstract

The invention relates to a cable material, in particular to an anti-deformation heat preservation compound ethylene propylene diene monomer cable material and a preparation method thereof. The anti-deformation heat preservation compound ethylene propylene diene monomer cable material is prepared from, by weight parts, 0.01-0.02 part of nano silver, 18-25 parts of colemanite powder, 12-16 parts of white carbon black, 4-5 parts of magnesium oxide, 1-2 parts of methacrylic acid, 6-8 parts of dravite, 40-50 parts of ethylene propylene diene monomer, 0.5-1 part of silane coupling agent KH-560, 3-5 parts of antimonous oxide, 5-8 parts of tetrabutyl titanate, 4-6 parts of dioctyl phthalate, 20-28 parts of butyronitrile rubber, 1-2 parts of accelerant CBS, 5-8 parts of color concentrate, 1-2 parts of dicumyl peroxide and 2-3 parts of adjuvant. According to the cable material, the ethylene propylene diene monomer and the butyronitrile rubber are taken as basic materials, modified and processed dravite composite filler is taken as the auxiliary materials, and the curability of the compound rubber is improved effectively.

Description

technical field [0001] The invention relates to a cable material, in particular to an anti-deformation thermal insulation compound EPDM cable material and a preparation method thereof. Background technique [0002] Cable material is a general term for plastics used for wire and cable insulation and sheathing. It is made of rubber, plastic, nylon and other materials as base materials, combined with auxiliary components such as plasticizers, fillers, color masterbatches, and antioxidants. Different types of cables and The use environment has different requirements on the performance of cable materials. Most of the commercially available cable materials are not resistant to scratches and folds, are easy to corrode and oxidize the internal metal wires, have poor flame retardancy, cannot balance hardness and toughness, and are highly toxic when burned. Defects such as resistance to humidity, cold and heat restrict the safety and service life of cables. Therefore, it is urgent to ...

Different types of cables and The use environment has different requirements on the performance of cable materials. Most of the commercially available cable materials are not resistant to scratches and folds, are easy to corrode and oxidize the internal metal wires, have poor flame retardancy, cannot balance hardness and toughness, and are highly toxic when burned. Defects such as resistance to humidity, cold and heat restrict the safety and service life of cables. Therefore, it is urgent to develop new types of cable materials with balanced performance, environmental protection, safety, and strong practicability.
