| 目的 研究环氧树脂E-44改性丙烯酸树脂乳液的添加量和核壳设计温度对乳液性能影响规律。方法 采用自由基聚合方法合成环氧树脂E-44改性丙烯酸酯乳液，并进行乳液红外、吸水率、干燥性、附着力粒径等性能测试。结果 乳液在聚合物薄膜上的附着力随着E-44添加量的增加而变强；吸水率随着E-44添加量的增加先变差后变好，在添加量(质量分数)为5%时有最低值7.41%；乳液的干燥性会随着E-44添加量的不同而变化，无明显规律，但是添加量为5%时干燥性最好。结论 环氧树脂E-44的添加量为5%。核层设计温度为83 ℃，壳层设计温度为-11 ℃时，合成的环氧树脂E-44改性丙烯酸酯乳液的粒径59 nm，吸水率为9.2%，表面张力为35.5 mN/m；乳液的干燥性、稳定性和在聚合物薄膜PVC和PET上的附着力好。 |

| This paper studied the influence pattern of the adding content of epoxy resin E-44 modified polyacrylate emulsion and the core-shell design temperature on the emulsion performance. The epoxy resin E-44 modified polyacrylate emulsion was synthesized by radical polymerization. The performance tests of infrared ray, water absorbance, dryness and adhesive particle size were conducted. The adhesion of the emulsion on the poly film was stronger with the increase of the adding amount of epoxy resin E-44. The water absorbance firstly got worse then become better along with the adding of epoxy resin E-44 and reached to the lowest value of 7.41% at the adding amount (mass fraction) of 5%. The dryness fluctuated with the adding of epoxy resin E-44, showing no obvious patterns. The dryness was the best at the adding amount of 5%. In conclusion, the adding amount of epoxy resin E-44 was 5%. The particle size of the synthesized emulsion was 59 nm, the water absorbance was 9.2% and the surface tension was 35.5 mN/m when the design temperatures of core layer and core shell were 83 ℃ and -11 ℃. The emulsion had good dryness, stability and adhesion on the polymer films PVC and PET. |
