以甲基丙烯酸十二氟庚酯(Actyflon-G04)为疏水功能单体，与γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH-570)和(甲基)丙烯酸酯单体等进行乳液共聚，制备低表面能氟硅丙共聚物乳液，可用于疏水涂层.考察硅单体KH-570和氟单体Actyflon-G04用量对乳液聚合转化率和凝胶量的影响，探讨共聚物类型和Actyflon-G04用量对共聚物乳液涂层水接触角的影响，并考察涂膜的综合性能.结果表明：当KH-570和Actyflon-G04用量分别为共聚单体总质量的2%和15%时，单体转化率可达97%以上；聚合乳液无凝胶，所合成的氟硅丙共聚物乳液综合性能最佳，其在铁片表面涂层对水接触角为95°、涂膜附着力1级、铅笔硬度为HB、耐冲击力>50 cm.氟硅丙共聚物乳液在不同材质基板表面涂层对水的接触角略有差异，其中在玻璃表面水接触角最高，可达108°.

Fluorine &silicon containing acrylate copolymer emulsion for hydrophobic coatings was pre-pared by emulsion polymerization ofγ-methacryloxypropyltrimethoxyl silane(KH-570) and(meth)acrylates in the presence of dodecafluoroheptyl methacrylate(Actyflon-G04) as the hydrophobic monomer. Effects of KH-570 and Actyflon-G04 content on monomer conversion and gel formation were investigated. Effect of copolymer types and Actyflon-G04 content on contact angle was discussed and the overall performances of the coatings were studied. The monomer conversion was achieved up to 97 %,and copolymer coating has excellent properties with water contact angle of 95° on steel,adhesion of grade 1,pencil hardness of HB,lar-ger than 50 cm of impact resistance,when the contents of KH-570 and Actyflon-G04 were 2% and 15% of the total mass of copolymerized monomers,respectively. In addition,the water contact angles on different substrates were slightly different with the largest one of 108° on glass substrate.
