Abstract

The invention discloses a novel slow-release environment-friendly stabilizer applied to a U-PVC large-caliber water supply accessory. The stabilizer comprises the following components in percentage byweight: 28% of zinc stearate, 8% of calcium stearate, 5% of Sika, 5% of uracil, 30% of zeolite, 5% of calcium hydroxide, 4% of an antioxidant, 10% of a synergistic heat stabilizer and 5% of polyol. The invention relates to the technical field of production of U-PVC large-caliber water supply accessories. The novel slow-release environment-friendly stabilizer applied to the U-PVC large-caliber water supply accessory solves the problem that a stabilizer which is high in stability, proper in cost, capable of improving the stability of a product and specially used for production of the U-PVC large-caliber water supply accessory does not exist in the prior art.

Description

technical field [0001] The invention relates to the technical field of production of U-PVC large-caliber water supply fittings, in particular to a new slow-release environmentally friendly stabilizer applied to U-PVC large-caliber water supply fittings. Background technique [0002] As a general-purpose plastic material, rigid polyvinyl chloride (PVC-U) has the characteristics of flame retardant, chemical corrosion resistance, wear resistance, good insulation and high mechanical strength. Therefore, PVC-U is widely used in chemical industry, building materials, light industry , home appliances, packaging and other fields. In recent years, with the continuous advancement of urbanization in our country, plastic materials have developed rapidly in the domestic building material pipeline industry, and have gradually replaced traditional metal pipes, and the caliber of products used is also increasing. [0003] In the production process of PVC raw materials for PVC-U large-diame...
