Abstract

The invention relates to a nontoxic stabilizing agent for wires and cables. The nontoxic stabilizing agent comprises the following raw materials in parts by weight: 25-55 parts of an allantoin calcium-zinc compound, 6-14 parts of phosphite ester, 5-12 parts of polyol, 12-20 parts of a nitrogenous organic compound, 3-10 parts of hydrotalcite, 5-15 parts of beta-diketone, 2-8 parts of an anti-oxidant and 3-8 parts of polyethylene wax. According to the nontoxic stabilizing agent, allantoin of an amphoteric polyfunctional group compound is utilized to prepare the allantoin calcium-zinc compound, and the allantoin calcium-zinc compound is used in an environment-friendly stabilizing agent; with the assist of a series of auxiliary stabilizing agents and other addition agents, the prepared allantoin-based environment-friendly calcium-zinc stabilizing agent for the wires and cables has relatively good heat stability and ageing resistance, the insulativity achieves the national related requirements, toxic components are not contained, environmental protection is achieved, and meanwhile, solid products bring convenience for the transportation.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a non-toxic stabilizer for electric wires and cables. Background technique [0002] Plastics account for the vast majority of wire and cable covering materials in my country, and polyvinyl chloride occupies the main position of such plastics. The transformation of my country's power grid, the rapid development of the automobile industry and the communication industry have provided unprecedented opportunities for the development of wire and cable companies, and have also opened up broad prospects for the development of the PVC cable material industry. [0003] Tribasic lead sulfate, dibasic lead phosphite, lead stearate, etc. are traditional stabilizers commonly used in PVC cable materials. It has good insulation performance, excellent stability and low price, but lead is a heavy metal with strong toxicity and ecological pollution, which will cause great har...
