摘要：

为研究一种高效经济的织物阻燃整理剂，将种子乳液聚合法制备的聚偏二氯乙烯（PVDC）乳液与可膨胀石墨（EG）复配形成阻燃整理剂，研究该整理剂中EG与PVDC的不同配比对织物阻燃性能的影响，并测定整理织物的物理力学性能，通过扫描电镜和红外光谱分析整理剂的协同阻燃机制。研究结果表明：PVDC乳液具有高阻燃性，EG与PVDC的质量比为1：99时的整理剂协同阻燃效果最佳，续燃和阴燃时间均为0 s，损毁长度降低到96 mm，其在织物表面形成一层致密的炭层，热稳定性良好，且整理织物的断裂强力增加了158%。

Abstract:

In order to research an dfficient and economic flame retardant finising agent usrd in fabric, polyvinylidene dichloride (PVDC) emulsion produced by the method of seed emulsion polymerization and expansible graphite (EG) were compounded to form flame retardant finishing agent. Effects of the defferent ratios of EG and PVDC in the finishing agent on flame retardant peoperties of the fabric were researched, physical and mechanical peoperties of finished fabric were measured, and the collaborative flame retardant mechanism of the finishing agent was analyzed by scanning electron microscopy and infrared spectrum. The results showed that the PVDC emulsion had high flame retardancy, and the mass ratio of EG and PVDC (1：99) flame retardant had the best synergistic flame retardant effect, its afterflame time and afterglow time were 0 s, and damaged length was 96 mm, and the finishing agent formed a dense carbon layer on the fabric surface, and has good thermal stability, and breaking strength of the finished fabric increased by 158%.

Key words: polyvinylidene dichloride, expandable graphite, textile finishing, synergistic flame retardant
