Environment-friendly polyvinyl chloride cable sheathing compound

Abstract

The invention relates to an environment-friendly polyvinyl chloride cable sheathing compound mainly comprising the following materials in parts by weight: 40-45parts of polyvinyl chloride resin, 5-7parts of trioctyl trimellitate, 4-6 parts of dioctyl sebacate, 8-10parts of acetyl tributyl citrate, 5-7 parts of DX-360, 4-6parts of Ca-Zn composite stabilizing agent, 1-1.5 parts of epoxidized soybeanoil, 1-1.5 pats of diantimony trioxide, 10-30 parts of magnesium hydroxide and 10-13parts of fine calcium carbonate. The environment-friendly polyvinyl chloride cable sheathing compound technically satisfies European Union ROHS and REACH index requirements, resists ultraviolet irradiation, and the like, increases stability and anti-moisture absorption, prolongs a storage period and has high practicability, wide development prospect and large market potential. The environment-friendly polyvinyl chloride cable sheathing compound is successfully developed to supply raw material guarantee for designing and selecting an environment-friendly cable product which can simultaneously satisfy the European Union ROHS and REACH requirements, promotes the stable sustainable development of linked industries and conforms the development direction of products of new and high technologies of China.

Description

(1) Technical field [0001] The invention relates to the field of electric wire and cable processing, in particular, the invention is an environment-friendly polyvinyl chloride cable sheathing material. (2) Background technology [0002] With the deepening of people's understanding of pollution, the European Union's electrical and electronic ROHS Directive (EU Directive 2002 / 95 / EC) has six harmful substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). Make a restriction request. Among them, the content of cadmium is ≤100ppm, and the content of lead, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) is ≤1000ppm. For cable PVC materials, hexavalent chromium generally exists in the color masterbatch, lead generally exists in large quantities as a thermal stability additive, silver and cadmium may exist in various metal materials of cables, ...

AI Technical Summary

Problems solved by technology

Due to the backwardness of formula technology and lack of testing methods, the product quality is not guaranteed, and most of the environmental protection indicators remain at the level of lead-free and meeting the requirements of ROHS indicators.

Publicly reported literature is also limited to the research and development of environmentally friendly PVC cable materials that meet the ROHS index

There are almost no reports on environmentally friendly PVC cable sheathing materials that meet the requirements of the EU ROHS directive and the REACH directive

Through research, sampling, testing and analysis, our company found that the environmentally friendly PVC cable sheath materials available in China actually cannot meet the requirements of the EU ROHS directive and REACH directive at the same time.
