Problems solved by technology

[0004] In the injection molding production process of PVC pipe fittings, because PVC is a heat-sensitive material, its injection molding process is poor. The reason is that the high melt temperature or long heating time can easily decompose the PVC material and affect its plasticization. performance

Abstract

The invention relates to a magnesium-aluminum-zinc modified non-toxic composite environment-friendly stabilizer for a U-PVC transparent injection molded part product. The stabilizer is composed of 169-420 kg of fatty acid calcium-zinc composition, 150-280 kg of magnesium-aluminum-zinc composition, 20-87 kg of antioxidant 1076, 0-150 kg of hydrotalcite, 28-40 kg of dehydroacetic acid or sodium dehydroacetate, 24-49 kg of stearoyl benzoyl methane and 261-445 kg of high-molecular ester base calcium. The stabilizer is used for injection molding of the U-PVC transparent injection molded part, and is good in plasticizing effect, good in stabilizing effect, smooth in processing and capable of achieving continuous processing; the inner surface and the outer surface of a processed pipe are smooth,the transparency is high, the mechanical property meets various requirements of the national standard, and the stabilizer is free of toxins and environment-friendly; the magnesium-aluminum-zinc composition and the fatty acid calcium-zinc composition are simultaneously used in the formula, so that the product compatibility, the processing stability and the long-term stability are coordinated and unified, and the product has good comprehensive performance.

Description

technical field [0001] The invention relates to a stabilizer, in particular to a magnesium-aluminum-zinc modified nontoxic composite environment-friendly stabilizer for U-PVC transparent injection molding parts. Background technique [0002] PVC material has been widely used because of its wide range of uses, good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics. At present, PVC materials and related products can be seen everywhere in people's lives, such as PVC foam materials, PVC stationery, PVC threading pipes, PVC cable insulation, PVC water pipes and other pipes, PVC plastic doors and windows, PVC plastic bags, PVC film, PVC Leather, etc. In practical use, PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives to make them have excellent stability, toughness, ductility, strength, weather resistance and excellent The ge...
