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 partial or complete replacement of pentaerythritol with wood flour as the carbon source of intumescent flame retardant was used to study the effect of wood flour on the thermal degradation and flame retardancy of LLDPE intumescent flame retardant system. The results show that wood flour has little effect on the thermal degradation behavior of the expanded system. When the mass content of wood flour is 20%, the flame retardant effect of the expanded system is the best.
