Abstract

The invention discloses an environment-friendly stabilizer with low processing temperature and simplicity in plasticization for wires and cables. The stabilizer is prepared from the following components by weight: 45-220kg of a fatty acid calcium-zinc composition, 10-100kg of calcium stearate, 1-10kg of an antioxidant 1076, 3-21kg of stearoylbenzoylmethane, 30-100kg of hydrotalcite, 5-120kg of 2-oxazolidinone and 20-200kg of inorganic hydroxides. The stabilizer disclosed by the invention is used for manufacturing wire and cable colloidal particles, the processing temperature of the stabilizer is 20-30 DEG C lower than that of a compound lead stabilizer, the temperature of each section can be controlled to be 120-130 DEG C for a conical twin-screw extruder, and the energy can be saved; the colloidal particles are good in plasticization, and the wire surface is bright; and moreover, the produced colloidal particle Congo red time is longer than or equal to 60 minutes, and the product is excellent in humidity resistance, particularly is not separated out on a black wire, is good in flowing property and suitable for highly filling wires and also can be applied to medium/low-temperature wires specified in GB8815.

Description

technical field [0001] The invention relates to a PVC production stabilizer, in particular to an environment-friendly stabilizer for electric wires and cables which is easily plasticized at a low processing temperature. 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, lea...
