Environment-friendly calcium-zinc stabilizer capable of improving electrical properties of wires and cables

Abstract

The invention discloses a green and environment-friendly calcium-zinc stabilizer capable of improving the electrical properties of electric wires and cables. ‑10 parts by weight of blown sand, 5‑10 parts by weight of polyethylene wax, 1‑10 parts by weight of stearyl benzoylmethane, 1‑5 parts by weight of superfine kaolin, 1‑5 parts by weight of ultraviolet rays Absorbent UV-327 and 10-20 parts by weight of scallop shell powder. The stabilizer obtained in the invention can effectively improve the thermal performance and the mechanical performance of the electric wire and cable material, has good comprehensive performance, and fills a gap in the market.

Description

technical field

[0001] The invention relates to the technical field of plastic stabilizers, in particular to an environmentally friendly calcium-zinc stabilizer that can improve the electrical properties of electric wires and cables. Background technique

[0002] With the development of society, the demand for environmentally friendly cable materials is rapidly increasing. Developed countries such as Europe and the United States have successively formulated environmental protection standards for heavy metal elements such as lead, cadmium, and mercury, and harmful substances such as polybrominated biphenyls, such as British-European standards. BSEN. 71. ENll22, USEPA3050B, etc. Environmentally friendly cable materials have become an important topic in the current research and development and production of cable materials. The more commonly used heat stabilizers include lead salts, organotins, metal soaps, rare earths, and calcium-zinc stabilizers. Lead salt stabilizers used...
