| 摘 要： | 以硝化纤维(NC)、异佛尔酮二异氰酸酯(IPDI)、二羟甲基丙酸(DMPA)等为主要原料,制得自乳化型水性硝化纤维乳液,再加入环氧树脂E-44,环氧基与羧基反应制备出环氧树脂改性的水性硝化纤维胶黏剂乳液。通过傅里叶变换红外光谱(FT-IR)、透射电子显微镜(TEM)、热失重分析(TGA)法等测试手段,研究了环氧树脂E-44和DMPA的含量对胶黏剂性能的影响。结果表明,当ω(环氧树脂E-44)=5%、ω(DMPA)=3.5%时,环氧树脂改性水性硝化纤维胶黏剂的耐水性、耐热性和柔韧性优异,粘接强度可达7.7 N/mm。

| Abstract: | Self-emulsified waterborne nitrocellulose emulsion is prepared with nitrocellulose(NC),isophorone diisocyanate(IPDI) and dimethylol propionic acid(DMPA) as main materials,and then reacted with epoxy resin E-44.Waterborne nitrocellulose adhesive emulsion modified by epoxy resin is synthesized through the reaction between epoxy group and carboxyl.The effect of E-44 and DMPA content on the properties of adhesive is investigated by FT-IR,TEM,TGA and other testing means.The results show that when the mass fracti... |
