Modified silicon resin-doped neoprene rubber-based cable material and preparation method thereof

Abstract

The invention relates to a cable material, in particular to a modified silicon resin-doped neoprene rubber-based cable material and a preparation method thereof. The cable material is prepared from, by weight, 42-54 parts of neoprene rubber, 1-3 parts of titanyl sulfate, 3-6 parts of palm oil, 5-8 parts of lignite wax, 12-16 parts of silicon resin, 20-28 parts of ethylene propylene diene monomer rubber, 2-4 parts of calcium stearate, 35-42 parts of activated calcium carbonate, 1-2 parts of an antioxidant, 15-18 parts of dipropylene glycol dibenzoate, 3-5 parts of calcium gluconate, 4-5 parts of medium chain triglyceride, 1-2 parts of an accelerant TMTD, 8-10 parts of color masterbatch and 2-3 parts of an auxiliary. According to the cable material, the high polymer materials such as neoprene rubber, ethylene propylene diene monomer rubber and silicon resin are taken as a mixed resin base material, the composite activated calcium carbonate which is processed through modification is taken as a reinforcement filler, the reinforcement effect is good, and the auxiliary and the other materials are combined, so that the cable material shows the more excellent cold resistance than that of a traditional neoprene rubber cable material.

Description

technical field [0001] The invention relates to a cable material, in particular to a neoprene-based cable material doped with modified silicone resin 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 d...

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.
