摘要: 针对蚕丝用环保耐久性阻燃剂品种较少的问题,研究了自制非水溶性阻燃剂甲基丙烯酰氧乙基二乙基磷酸酯(DEMEP)的乳化方法、乳液稳定性及乳液粒径,添加非离子乳化剂Tween 80与Span 80按质量比2:1复配的混合乳化剂10% ~15%(对DEMEP质量百分数)时可得到静置稳定性及热稳定性均良好的半透明乳液。将制得的乳液与蚕丝在水介质中进行接枝共聚反应,考察了不同溶剂对蚕丝表面阻燃剂均聚物的洗除效果,得出丙酮与甲醇萃取4~6h后,均聚物可基本去除。经DEMEP处理的丝织物白度及透气性均随接枝率的提高而有所下降,并采用微型燃烧量热仪测量阻燃整理前后毫克级丝织物的燃烧情况,得知阻燃整理后,丝织物的热释放速率、总热释放量均大大下降,阻燃效果良好。

Abstract: The paper dealed with the application of a self-prepared water insoluble flame retrardant diethyl-2-(methacryloyloxyethyl)phosphate(DEMEP) onto silk fabric. Emulsification of DEMEP, the stability and the size distribtion of the DEMEP emulsion were investigated. Adding 10% ~15%(Mass percentage of DEMEP) mixture emulsifier contained Tween 80 and Span 80 at the mass ratio of 2 to 1 can acquire translucent emulsion with good thermal and quiescence stability. DEMEP emulsion was applied to be grafted onto silk fabric, the removal of DEMEP homopolymer on silk fabric with different solvents were explored, and the result showed that acetone and methanol are good solvens for DEMEP homopolymer after 4 to 6 h treatment. The whiteness and permeability of DEMEP grafted silk fabric decreased with increasing graft yield. Micro-scale combustion calorimetry tested combustion behaviour of DEMEP treated silk fabric at milligram level, and the result showed that the heat release rate and total heat release have significant decrease compared with control silk fabric. The test results showed after treated with DEMEP, silk fabric can acquire good flame retardancy property.
