摘 要: 本文介绍的环保型钙锌稳定剂是一种应用广阔的热稳定剂,选择合适的钙锌配比可以达到最大的协同效果,使PVC获得较好的初期着色性和长期稳定性。除了硬脂酸钙/硬脂酸锌体系外,其他有效的有机钙锌体系也被开发出来。辅助热稳定剂的加入能提高钙锌稳定剂的热稳定效果。 Environment-friendly calcium and zinc stabilizer is a widely used heat stat)luzer. ~ l~ propriate ratio of calcium and zinc can achieve the best synergistic effect so as to make PVC obtain good initial coloring stability and long- term stability. Besides calcium stearate/zinc stearate system, other effective organic calcium and zinc systems have also been developed. The addition of auxiliary heat stabilizers can improve the thermal stability of calcium and zinc stabilizer.
