摘要
稳定剂是能防止或抑制PVC树脂在成型和使用过程中由于光、热、氧和机械作用而引起的分解的物质。本文通过热稳定剂的作用机理、主要性能等的论述,指出了常用热稳定剂对PVC塑料异型材变色的影响,最后指出了发展绿色环境保型稳定剂应注意的一些事项。
Stabilizer is a substance able to prevent or inhibit the decomposition of PVC resin in molding and using processes arising of the effects of light, heat, oxygen and mechanic movements. This article describes the working principles and main properties of heat stabilizer, and on this basis points out the impacts of common heat stabilizers on the discoloration of PVC plastic profiles, and finally points out something to be noted in developing green stabilizers.
