Embodiment 1

[0018] Weigh 15kg of zinc stearate, 20kg of calcium stearate, 20kg of stearyl benzoylmethane, 30kg of zeolite, 10kg of sek, and 5kg of sodium perchlorate, put them into the mixer, and knead evenly to obtain an environment-friendly high temperature resistant PVC calcium zinc composite stabilizer.

Embodiment 2

[0020] Weigh 15kg of zinc stearate, 20kg of calcium stearate, 20kg of dibenzoylmethane, 30kg of zeolite, 10kg of sek, and 5kg of sodium perchlorate, put them into the mixer, and knead them evenly to obtain environmentally friendly high-temperature resistant PVC calcium Zinc complex stabilizer.

[0021] When the environment-friendly high-temperature-resistant PVC calcium-zinc composite stabilizer of the above-mentioned embodiment 1 and embodiment 2 is actually applied to PVC products, its formula can refer to Table 1:

Abstract

The invention discloses an environmental protection and high temperature resistant PVC (polyvinyl chloride) compound calcium-zinc stabilizer. The stabilizer comprises the following components in percentage by weight: 10 to 20% of fatty acid zinc, 10 to 40% of fatty acid calcium, 10 to 20% of beta-diketone, 20 to 40% of zeolite, 5 to 15% of THEIC (trihydroxyethyl isocyanurate) and 5 to 10% of sodium perchlorate. The environmental protection and high temperature resistant PVC compound calcium-zinc stabilizer disclosed by the invention has good stability in the earlier stage, the middle state and the later stage, and can protect PVC from aging comprehensively in a three-dimensional manner, so that the integrated heat-proof stabilizing effect of the product far exceeds the effect of the ordinary monomer calcium-zinc stabilizer, product performances are completely in conformity with a standard requirement of 105 DEG C of UL62, and the product has an excellent appearance, furthermore, the product does not contain heavy metals, such as lead and cadmium, and completely does not contain substances in SVHC (Substances of Very High Concern) in the latest EU (European Union) REACH instruction, thereby meeting the new development trend in the world today, and being a material with wide application prospects.

Description

technical field [0001] The invention relates to a PVC stabilizer, in particular to an environment-friendly high-temperature-resistant PVC calcium-zinc composite stabilizer with excellent initial color. Background technique [0002] The stabilizers used in large quantities in the PVC industry are heat stabilizers containing lead and cadmium. They are low in price and superior in performance. It causes serious pollution to the environment in which we live, and then threatens people's health. How to remove lead and cadmium in the PVC manufacturing process without losing the superior performance of the original lead and cadmium stabilizers is a difficult problem for every PVC processing industry. In the 1980s, the NCI of the United States proposed that DOP was suspected of causing cancer, which led to the "environmental hormone" storm, and then it was recognized by the European Union, and then its imported children's toys were restricted. How to use new technology and new tech...
