• Abstract: Polyacrylate emulsions are widely utilized due to their excellent adhesive properties, environmental friendliness, and film-forming capabilities. However, the application of polyacrylate films is somewhat limited by their inherent drawbacks, such as thermal adhesion, cold brittleness, and flammability. Consequently, there is a need for their modification. In this thesis, a modified acrylate emulsion was prepared using 2-hydroxyethyl methacrylate phosphate (PM-2), vinyltriethoxysilane (TEOS), and 2-acrylamido-2- methylpropanesulfonic acid (AMPS) as functional monomers through the seed emulsion polymerization method. The experimental results demonstrated that when BA + MMA constituted 30% of the composition, and the emulsifier, initiator, PM-2, TEOS, and AMPS accounted for 6%, 1.2%, 2%, 4%, and 3% of the monomer quantity, respectively, the modified emulsion exhibited good stability. The tensile strength of the modified polyacrylate film increased from 3.21 MPa before modification to 7.12 MPa after modification, and the flame retardant performance reached the highest level of 94V-0. It is evident that modification can significantly enhance the mechanical strength and flame retardant properties of polyacrylate films. This research provides a reference for further study and application of polyacrylate emulsion. 聚丙烯酸酯乳液因具有优良的粘结力、环保性以及成膜性，而被广泛应用。但是，聚丙烯酸酯胶膜存在热粘冷脆且易燃的缺点，其应用受到了限制。因此，需要对其进行改性。本论文以2-羟乙基甲基丙烯酸酯磷酸酯（PM-2）、乙烯基三乙氧基硅烷（TEOS）、2-丙烯酰胺-2-甲基丙磺酸（AMPS）作为功能单体，采用种子乳液聚合法，制备了改性丙烯酸酯乳液。实验结果表明，当BA+MMA为30%，乳化剂、引发剂、PM-2、TEOS和AMPS分别为单体用量的6%、1.2%、2%、4%、4%和3%时，制备的改性乳液稳定性良好，拉伸强度从改性前的3.21MPa提升到改性后的7.12MPa，改性聚丙烯酸酯胶膜的阻燃性能达到最高阻燃级别94V-0级。由此可见，改性能显著提高聚丙烯酸酯胶膜的力学强度和阻燃性能。本研究为聚丙烯酸酯乳液的进一步研究和应用提供了参考。
