以十二烷基硫酸钠（SDS）和异构十三醇聚氧乙烯醚（E1309）为乳化剂，丙烯酸丁酯（BA）为软单体，甲基丙烯酸甲酯（MMA）为硬单体，甲基丙烯酸酯基烷氧基磷酸酯（PAM-100）为含磷单体，双丙酮丙烯酰胺（DAAM）为交联单体，磷酸钠为pH调节剂，过硫酸铵（APS）为引发剂，采用乳液聚合法制备了含磷聚丙烯酸酯乳液。研究了乳化剂、PAM-100、磷酸钠用量对乳液及整理织物综合性能的影响。研究结果表明：当SDS与E1309质量比为1∶2，乳化剂质量分数（相对于乳液总质量而言）为0.6%,BA和MMA质量分数（相对于乳液总质量而言）分别为24%和6%,PAM-100、磷酸钠、DAAM和APS质量分数（均相对于单体总质量而言）分别为12%、10%、4%和1%时，聚合乳液的单体转化率为95.22%，乳液粒径为329.37 nm，乳液Zeta电位为-60.57 mV。将所制得乳液用于棉织物的整理，整理织物的断裂强力提高，白度略有下降，成炭性能明显提高。

Phosphorous-containing polyacrylate emulsion was prepared by emulsion polymerization method with sodium dodecyl sulfate(SDS) and isotridecanol polyoxyethylene ether(E1309) as emulsifiers,butyl acrylate(BA) as soft monomer,methyl methacrylate(MMA) as hard monomer,methacrylate-based alkoxy phosphate(PAM-100) as phosphorus-containing monomer,diacetone acrylamide(DAAM) as crosslinking monomer,sodium phosphate as pH regulator,and ammonium persulfate(APS)as initiator. The effects of emulsifier,PAM-100 and sodium phosphate dosage on the comprehensive properties of emulsion and finished fabric were studied. The research results showed that when the mass ratio of SDS to E1309 was 1∶2,the mass fraction of emulsifier(relative to the total mass of emulsion)was 0.6%,the mass fraction of BA and MMA(relative to the total mass of emulsion)was 24% and 6%,respectively,and the mass fraction of PAM-100,sodium phosphate,DAAM and APS(all relative to the total monomer mass)was 12%,10%,4% and 1%,respectively,the monomer conversion rate of polymerized emulsion was 95.22%,the particle size of emulsion was 329.37 nm,and the Zeta potential of emulsion was-60.57 mV. When the prepared emulsion was used for cotton fabric finishing,the breaking strength of finished fabric was improved,the whiteness was slightly reduced,and the char-forming performance was obviously improved.
