摘要
介绍了新型辅助热稳定剂β -二酮类化合物T -3 86的制备及其在硬质PVC中的应用 ,阐明了T -3 86的稳定机理及其应用效果。结果表明 ,T -3 86具有良好的防止初期着色性和长期稳定性 。
The preparation and application of auxiliary heat stabilizer β-diketone,named as T-386 for hard PVC was introduced. The stabilization mechanism and application effect of T-386 was also given. The results showed that the primitive colouring of hard PVC could be postponed and even prevent by addition of T-386, its synergistic effect with other stabilizers, such as CaSt, ZnSt was displayed.
