基于ATRP接枝DMMEP的棉织物阻燃整理
|
摘要
以甲基丙烯酰氧乙基二甲基磷酸酯(DMMEP)为功能单体,利用原子转移自由基聚合反应(ATRP)对棉织物进行阻燃整理,分析了功能单体、催化剂浓度、反应温度和反应时间对接枝效果的影响。得到优化的整理工艺条件:DMMEP浓度0.16 mol/L,CuBr浓度1.5 mmol/L,反应温度80℃,反应时间2 h。在该条件下测得棉织物极限氧指数达到25.3%,电镜照片显示燃烧炭渣表面产生了大量胀破的泡状突起,红外ATR吸收光谱验证棉织物通过ATRP技术成功接枝了DMMEP,X-射线衍射曲线证实棉纤维的晶型结构未发生明显改变。
Flame retardant finishing of cotton fabric is carried out by ATRP using DMMEP as a functional monomer. The effects of functional monomer, catalyst concentration, reaction temperature and reaction time on the grafting effect are analyzed. The obtained optimum process conditions are DMMEP0.16 mol/L, CuBr 1.5 mmol/L, and reaction at 80 ℃ for 2 h. Under these conditions, the limit oxygen index of cotton fabric can reach 25.3%. The electron micrograph shows that a large number of blistering protrusions are formed on the surface of the burning carbon residue. The infrared ATR absorption spectrum verifies that the cotton fabric is successfully grafted with DMMEP based on ATRP. The X-ray diffraction curve confirms that there is no significant change in the crystal structure of the cotton fiber.
