一种聚硅氮烷在PVC热稳定剂中的应用
首发时间:2019-06-20
摘要:以聚硅氮烷、水滑石、硬脂酸锌、润滑剂、抗氧剂、二氧化硅等原料复配出高效热稳定剂产品,通过与PVC、DOP配混后使用双辊压片机制成PVC样片,测试样片透明性、热烘箱稳定性、刚果红热稳定性及其它性能,最终确定当聚硅氮烷10-20份、硬脂酸锌10-20份、水滑石30-50份时产品稳定性较好、透明性高,适用于高透明稳定性要求较高的体系中。

The application of one polysilazane in PVC heat stabilize
Abstract:With polysilazane zinc stearate, hydrotalcite, antioxidants, silicon dioxide as a heat stabilizer products, with PVC, DOP used after mixing mechanism of double roller presser into PVC samples, by studying the different proportion of each samples with transparency, thermal stability of the oven, Congo red heat stability and other performances, eventually determine when polysilazane 10-20,zinc stearate,10-20, hydrotalcite 30-50, product stability, high transparency, better applied to high transparent system with high stability requirements.
