摘要
以木粉部分或完全代替季戊四醇作为膨胀型阻燃剂的碳源,研究木粉的加入对LLDPE膨胀阻燃体系热降解和阻燃性的影响。研究表明:木粉对膨胀体系的热降解行为影响不大,当木粉在成炭剂中的质量含量为20%时,膨胀体系的阻燃效果最好。
The wood fiber was used as a char forming agent to all or partly replace pentaerythitol in intumescent flame retardants,and investigated to effect on thermal degradation and flame retardancy of LLDPE intumescent system. It was shown that the thermal degradation behavior was generally as same as used PER as char forming agent,and when the amount of wood fiber was 20 percent of the whole char forming agent,the LOI reached a climax.
