摘　　要：采用丙烯酸树脂共混与丙烯酸树脂接枝共聚两种方法改性水性硝化纤维乳液,通过红外光谱,热重分析,表面水接触角,透射电子显微镜检测等手段对所得乳液和涂膜结构与性能进行表征.结果表明,两种改性方法都提高了乳液的稳定性、涂膜耐水性及热稳定性等综合性能.通过对比分析发现接枝共聚改性对涂膜的综合性能的提高更显著.In this paper,waterborne nitrocellulose emulsion was modified in two ways,acrylic acid resin blending modification and acrylic acid resin graft copolymerization modification. Structure and properties of the emulsion and film were characterized by FT-IR,TGA,Surface water contact angle detection and SEM etc.The results showed that the stability of the emul-sion,water resistance and thermal stability of the film were improved by these two kinds of modification methods.The improvement of graft copolymerization modification to the com-prehensive properties of the coating film is more remarkable than the result of blend modifi-cation.
