【摘要】 以甲基四氢苯酐(MTHPA)和聚乙二醇600(PEG600)为原料,合成了一种双端羧基化合物(MTHPA-PEG600-MTHPA);然后将其与环氧树脂(EP)反应,制备出一种非离子型水性EP。结果表明:该水性EP可与任何比例的水在搅拌条件下配成水乳液,并且其经3 000 r/min离心分离30 min后无分层现象,说明其稳定性较好;该水性EP的平均粒径为77 nm,其胶膜的铅笔硬度为3H,并且胶膜的附着力、耐水性、耐酸性和耐溶剂性等俱佳。更多还原

【Abstract】 With methyl tetrahydrophthalic anhydride(MTHPA) and polyethylene glycol 600(PEG600) as raw materials,a two-terminal carboxyl compound(MTHPA-PEG600-MTHPA) was synthesized.Then a non-ionic waterborne EP(epoxy resin) was prepared by polymerization between MTHPA-PEG600-MTHPA and EP.The results showed that the water emulsions with better stability between the waterborne EP and any proportion water could be made by mix round because the emulsion stratification after 3 000 r/min for 30 min wasn’t generated.The waterborne EP film with average diameter at 77 nm and pencil hardness at 3H hat better adhesion,water resistance,acid resistance and solvent resistance.更多还原
