【摘要】 研究了Ｓｂ－Ｓｉ超细复合阻燃剂的热稳定性、阻燃性及其对软质ＰＶＣ力学性能的影响。结果表明，与超细Ｓｂ２Ｏ３相比，Ｓｂ－Ｓｉ有助于提高软质ＰＶＣ的热稳定性及拉伸强度，氧指数达难燃标准（添加５份）。更多还原

【Abstract】 The heat stability, burning and mechanical behavior of plasticized PVC treated with complex flame retardant Sb Si were studied Results showed that compared with ultrafines of pure Sb 2O 3, Sb Si can improve the heat stability and tensile strength of plasticized PVC, and limited oxygen index (LOI) can reach 27 0 when portion of Sb Si in PVC was five更多还原
