Abstract

The invention discloses an environment-friendly anti-oxidation cable protective sleeve material. The material comprises the following raw materials in parts by weight: 30-40 parts of ethylene-propylene rubber, 10-16 parts of butyl rubber, 10-15 parts of epoxy resin, 4-10 parts of organic silicon resin, 4-8 parts of an aluminum hydroxide colloid, 5-12 parts of glass fibers, 0.7-1.3 parts of paraffin oil and 1-5 parts of talcum powder, 4-9 parts of diatomite, 0.5-3 parts of zinc stearate, 0.6-1.5 parts of a vulcanizing agent DPC, 2-5 parts of a coupling agent, 1-4 parts of an assistant crosslinker TAIC, 1-4 parts of an anti-aging agent and 1.5-4 parts of an antioxidant. The preparation process of the protective sleeve material is as follows: adding the ethylene propylene-rubber, the butyl rubber, the epoxy resin and the organic silicon resin into a screw extruder, carrying out fusion for 10-20 minutes, controlling the melting temperature to be 125-135 DEG C, and then adding the remainingraw materials, carrying out extrusion after the fusion is carried out for 20 minutes, placing the extruded material in a flat vulcanizing machine, and carrying out pressing and crushing to obtain theenvironment-friendly anti-oxidation cable protective sleeve material. The protective sleeve material has excellent oxidation resistance, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to an environment-friendly anti-oxidation cable protective sheath material. Background technique [0002] With the rapid development of my country's communication industry, the demand for communication cables as arteries and blood vessels for signal transmission is also increasing day by day. The heat resistance of cable rubber sheaths on the market is generally poor. Using them at high temperatures can easily lead to problems such as premature aging, cracking and stickiness on the surface, and the surface will fall off for a long time, resulting in loss of function, and the cable will be discarded. Moreover, with the strengthening of people's awareness of environmental protection and the introduction of environmental protection regulations, halogen-free flame-retardant technology will gradually replace halogen-free flame-retardant technology. For a long time, the amount of polyvi...
