Abstract

The invention discloses a composite calcium-zinc heat stabilizer. The composite calcium-zinc heat stabilizer is prepared from the following raw materials by weight percent: 20 to 35 percent of zinc stearate, 5 to 15 percent of calcium acetylacetonate, 3 to 8 percent of beta-diketone, 20 to 30 percent of zeolite, 5 to 10 percent of hydrotalcite, 0 to 40 percent of calcium carbonate, and 1 to 15 percent of antioxidant. The composite calcium-zinc heat stabilizer and preparation method thereof are excellent in performance, low in cost, simple in production process, capable of solving the problem that the heat resistance of PVC in the processing process is poor, good in stabilizing effect in the application process, capable of obviously improving defects such as zinc burning, and good in application effect.

Description

technical field [0001] The invention relates to the field of heat stabilizer preparation, in particular to a calcium-zinc composite heat stabilizer and its application and preparation method. Background technique [0002] Polyvinyl chloride plastic (PVC) is currently the most widely used thermoplastic, with excellent performance and low cost, it is widely used in various fields. However, due to the molecular structure of PVC, the heat resistance is poor, and it degrades with the dehydrochlorination reaction at a temperature exceeding 100 degrees Celsius, while the processing temperature of conventional PVC is around 170 degrees Celsius. At this temperature, the degradation rate is faster. The performance attenuation is serious, which restricts the application of PVC. [0003] In order to solve this problem, it is necessary to add a certain amount of heat stabilizer to inhibit its degradation during processing. Currently, the heat stabilizers used for PVC mainly include lead...
