复合光稳定剂JC-568在PVC-U型材中的耐候稳定作用

The weather resistance effect of composite light stabilizer JC-568 in PVC-U section materials

通过试验,研究了复合光稳定剂JC-568在PVC-U型材中的耐候稳定作用。结果表明,复合光稳定剂JC-568用于PVC-U型材,适用于一般加工要求,可促进塑化,表现出明显的光、氧稳定作用;PVC-U型材制品经6 000 h老化后,各项指标满足GB/T 8814-2004要求。

The weather resistance effects of composite light stabilizer JC-568 in pvc- U section materials were studied through experiments. The results showed that the application of composite light stabilizer JC- 568 in PVC - U section materials could meet the general processing requirement,promote plasticization and showed obvious stabilization to light and oxygen. The obtained PVC - U section products could meet the requirement of GB/T 8814 - 2004 after 6 000 hours ageing.
