Problems solved by technology

PVC stabilizers mainly include lead salts, organotins, metal soaps and rare earths, etc. Among them, lead salts and heavy metals are toxic and harmful substances, and have gradually withdrawn from the stabilizer market; organotin stabilizers are effective and available It is used in transparent products, but the price is high; ordinary metal soaps have poor thermal stability; rare earths are a relatively new type of stabilizer, but affected by the shortage of rare earth resources, their prices are constantly rising

Abstract

The invention relates to a magnesium-aluminium-zinc modified nontoxic composite stabilizing agent for wire cable colloidal particles. The stabilizing agent of the invention is prepared by fatty acid calcium zinc composition, calcium stearate, an anti-oxidant 1076, stearoylbenzoylmethane, hydrotalcite, high-molecular ester calcium, acrylate copolymer, and polyethylene wax according to weight ratios. The stabilizing agent of the invention is applicable to wire cable colloidal particle manufacture; the prepared colloidal particle has Congo red time of not less than 60 min, has good moisture resistance, especially has no precipitates when used in black wires, has good flowing properties, is suitable for high-filling wires, and provides good surface smoothness for wires; fatty acid calcium zinc composition and high-molecular ester calcium are adopted in the formula; when compared with the preparation of traditional PVC stabilizing agents, the preparation of the stabilizing agent of the invention overcomes the disadvantage of pulverization difficulty for single use of zine stearate, provides good internal and external lubrication performance on PVC for the synthesized product, increases PVC compatibility, optimizes the comprehensive properties, and improves the processing stability and product long-term stability.

Description

technical field [0001] The invention relates to a stabilizer, in particular to a magnesium-aluminum-zinc non-toxic composite stabilizer used for wire and cable colloids. Background technique [0002] PVC (polyvinyl chloride) is one of the most widely used general-purpose plastics. In the wire and cable industry, PVC materials have been used for a long time due to their low manufacturing cost, excellent mechanical properties, good processing performance, corrosion resistance, and insulation. Materials have been widely used in the wire and cable industry. [0003] The stability of PVC material is a key factor affecting the quality of PVC products. Therefore, PVC stabilizers are usually added during the processing and preparation of PVC to improve its stability, so as to obtain high-quality and high-performance PVC products. PVC stabilizers mainly include lead salts, organotins, metal soaps and rare earths, etc. Among them, lead salts and heavy metals are toxic and harmful sub...
