乙酰丙酮类稀土复合热稳定剂及其PVC材料
摘要：
本发明公开了一种乙酰丙酮类稀土复合热稳定剂，包括乙酰丙酮稀土、有机锌金属化合物、辅助热稳定剂、润滑剂和填料；按重量计，乙酰丙酮稀土、有机锌金属化合物、辅助热稳定剂、润滑剂和填料的用量比为2.0～5.0：3.0～10.0：1.0～3.0：1.0～5.0：2.0～10.0。本发明还公开了一种应用乙酰丙酮类稀土复合热稳定剂的PVC材料，乙酰丙酮类稀土复合热稳定剂的用量为每100重量份PVC中配加1.0～5.0重量份乙酰丙酮类稀土复合热稳定剂。本发明能够有效改善PVC的初期着色性和长期热稳定性能，并降低PVC制品在生产过程中的平衡扭矩，提高生产效率。
摘要（英）：

The invention discloses an acetylacetone rare earth composite heat stabilizer. The acetylacetone rare earth composite heat stabilizer comprises acetylacetone rare earth, an organic zinc metal compound, an auxiliary heat stabilizer, a lubricant and a filler according-a weight ratio of (2.0-5.0):(3.0-10.0):(1.0-3.0):(1.0-5.0):(2.0-10.0). The invention also discloses a PVC material using the acetylacetone rare earth composite heat stabilizer. The acetylacetone rare earth composite heat stabilizer is added to PVC according to a weight ratio of (1.0-5.0):100. The acetylacetone rare earth composite heat stabilizer effectively improves the initial colorability and the long-term heat stability of the PVC, reduces the balance torque of the PVC product in the production process, and improves the production efficiency.
