Abstract

In this work, two types of tung oil-based auxiliary heat stabilizers (Ph-T and Ph-TO) were prepared for application in PVC processing. Combined with traditional heat stabilizers (calcium stearate and zinc stearate), Ph-T or Ph-TO can greatly alleviate “zinc burning” during the PVC processing which can significantly extend the processing time of PVC, so that improve the fault tolerance rate during PVC processing. Notably, the preparation process of Ph-T and Ph-TO is simple and does not require any heating, leading to reduced production costs and simplified manufacturing processes. Additionally, Ph-T or Ph-TO can enhance the plasticity of PVC, reducing the need for plasticizers and achieving multiple benefits with a single additive, which might be applicable in the production of blood bags or cable sheathing.

Highlights

Two types novel tung oil-based liquid auxiliary heat stabilizer for PVC processing were prepared. The preparation process is simple and does not require any heating.
These auxiliary heat stabilizers can greatly alleviate “zinc burning” during the PVC processing and which can significantly extend the processing time of PVC, improve the fault tolerance rate during PVC processing.
These auxiliary heat stabilizers can improve the overall plasticity of the PVC material and achieving the multi-effect.

用于聚氯乙烯加工的两种桐油基液体辅助热稳定剂的制备和特性

本研究制备了两种桐油基辅助热稳定剂（Ph-T 和 Ph-TO），用于聚氯乙烯加工。与传统的热稳定剂（硬脂酸钙和硬脂酸锌）相比，Ph-T 或 Ph-TO 可大大缓解 PVC 加工过程中的 "烧锌 "现象，从而显著延长 PVC 的加工时间，提高 PVC 加工过程中的容错率。值得注意的是，Ph-T 和 Ph-TO 的制备工艺简单，无需加热，从而降低了生产成本，简化了生产流程。此外，Ph-T 或 Ph-TO 还能增强聚氯乙烯的可塑性，减少对增塑剂的需求，实现一剂多效，可用于血袋或电缆护套的生产。制备过程简单，无需加热。这些辅助热稳定剂可大大缓解聚氯乙烯加工过程中的 "烧锌 "现象，显著延长聚氯乙烯的加工时间，提高聚氯乙烯加工过程中的容错率。这些辅助热稳定剂可提高 PVC 材料的整体可塑性，实现一举多得的效果。
