• 摘要： 為了提高丙烯酸酯乳液膠膜的阻燃性能、耐鹽離子、耐水性和耐有機溶劑性能，本論文以2-羥乙基甲基丙烯酸酯磷酸酯（PM-2）、乙烯基三乙氧基硅烷、2-丙烯酰胺-2-甲基丙磺酸（AMPS）作為改性劑，制備了改性丙烯酸酯乳液，實驗結果表明，當丙烯酸丁酯（BA）與甲基丙烯酸甲酯（MMA）的配比為46%∶54%時，乳膠膜成膜性能良好，膠膜柔韌性適中，外觀呈乳白色；當乳化劑的使用量為6%，KPS的用量為1.5%，乙氧基硅烷的用量為4%，AMPS的用量為1%，PM-2的用量為4%時，制備的改性聚丙烯酸酯乳液穩定性良好，儲存穩定性和耐鈣離子穩定性優異。乳膠膜耐有機溶劑性從被有機溶劑溶解提升到吸油率達到196.53%，拉伸強度達7.12MPa和斷裂伸長率可到450%。由此可見，改性能提高乳液的穩定性、乳膠膜的耐水性、耐有機溶劑性和力學強度有顯著改善。本研究為聚丙烯酸酯乳液進一步改性研究與應用提供了參考。
• In order to improve the flame retardancy, salt resistance, water resistance and organic solvent resistance of acrylate latex film, modified acrylate emulsion was prepared by using 2- hydroxyethyl methacrylate phosphate (PM- 2), vinyl triethoxy silane, 2- acrylamide -2- methyl propane sulfonic acid (AMPS) as modifier. When the ratio of butyl acrylate (BA) to methyl methacrylate (MMA) is 46%: 54%, the latex film has good film-forming performance, moderate flexibility and milky white appearance; When the amount of emulsifier was 6%, the dosage of KPS was 1.5%, the amount of ethoxy silane was 4%, the dosage of AMPS was 1%, and the amount of PM-2 was 5%, the emulsion had good stability, excellent storage stability and calcium tolerance. the prepared modified PDDA emulsion had good stability, storage stability and calcium ion resistance stability. The organic solvent resistance of the latex film improved from being dissolved in an organic solvent to having an oil absorption rate of 196.53 %. The tensile strength was 7.12 MPa after modification. Elongation at break can reach 450%. It can be seen that the stability of the comprehensive modified emulsion, the water resistance, organic solvent resistance, mechanical strength and flame retardancy of the latex film are significantly improved. This study provides a reference for further modification research and application of polyacrylate.
