Environment-friendly cable sheath material resisting high and low temperatures

Abstract

The invention discloses an environment-friendly cable sheath material resisting high and low temperatures. The environment-friendly cable sheath material resisting high and low temperatures is produced from the following raw materials in parts by weight: 20-50 parts of ethylene-vinyl acetate copolymer, 50-80 parts of linear low density polyethylene, 8-12 parts of aliphatic dibasic acid ester cold-resistant plasticizer, 35-40 parts of phthalate plasticizer, 7-15 parts of terephthalate plasticizer, 15-20 parts of intumescent phosphorus-nitrogen halogen-free flame retardant, 7-9 parts of calcium / zinc composite stabilizer, 0.5-0.8 part of lubricant, 22-25 parts of filler, 0.4-0.8 part of coloring agent, 0.3-0.8 part of tetrapropylpentaerythritol ester1010 and 3-6 parts of polyethylene wax. The environment-friendly cable sheath material resisting to high and low temperatures does not pollute the environment, and is low in price, convenient to process and manufacture, relatively excellent in cold resistance and heat resistance, and long in service life.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to an environment-friendly high and low temperature resistant cable sheath material. Background technique [0002] With the development of world economy and technology, the demand for wire and cable is increasing, and its performance requirements are getting higher and higher. Under the new economic situation and technical conditions, the development of the global wire and cable industry presents a new trend, and environmentally friendly cables have gradually become The development focus of global cables, in view of the serious pollution of conventional cables, a large number of dioxins, lead, cadmium, halides and other public hazards will appear in the process of manufacturing, use and waste disposal, developed countries use them Fewer and fewer, especially after the European Union formulated the ROHS directive, countries such as Europe, the United States, and Japan ...

AI Technical Summary

Problems solved by technology

[0003] The production process of traditional cable sheath materials often requires the presence of bromine and chlorine elements to ensure complete vulcanization, but the produced sheath materials will continuously release harmful substances such as bromide, chloride and sulfide, and these substances will It will cause corrosion to other parts covered in the cable sheath, which will cause the cable to fail to operate normally. However, the current cable sheath materials have not met the environmental protection requirements of sulfur-free and low-halogen. Reaching electric energy and transmitting signals is extremely important. For example, in Northeast China, especially in winter, the outdoor temperature can reach tens of degrees below zero, and some rubber materials have become cracked and brittle, which can seriously cause the leakage of cable conductors and cause serious damage to construction. And the use of cables brings inconvenience. How to prepare a cable sheath material that does not pollute the environment, is cheap, is convenient to process, and has excellent cold resistance and heat resistance, and a long service life has become a technical problem that needs to be solved at present.
