采用乳液聚合技术,以丙烯酸甲酯(MA)、丙烯酸乙酯(EA)、丙烯酸丁酯(BA)和苯乙烯(St)为基本聚合单体,丙烯酸(AA)、N-羟甲基丙烯酰胺(NMA)为活性单体,十二烷基硫酸钠(SDS)、复合脂肪醇聚氧乙烯醚(复合AEO)为乳化剂,过硫酸铵(APS)为引发剂,制备了5组聚丙烯酸酯粘合剂。研究了乳化剂、引发剂、活性单体对单体转化率及粘合剂的黏合性、耐沾污性、高温泛黄性和耐水性等应用性能的影响。研究结果表明:乳化剂及活性单体的配比与用量、引发剂的用量对丙烯酸酯单体的乳液聚合反应及其应用性能具有重要影响。
The main polymerization monomers of acrylic acid (AA), N-methylolacrylamide (MA), ethyl acrylate (EA), butyl acrylate (BA) and styrene (St) (NMA) as active monomer, sodium dodecyl sulfate (SDS), complex fatty alcohol polyoxyethylene ether (composite AEO) as emulsifier and ammonium persulfate (APS) as initiator to prepare five groups of polyacrylate Adhesive. The effects of emulsifiers, initiators and reactive monomers on the conversion of monomers and adhesive properties of adhesives, stain resistance, yellowing at high temperature and water resistance were studied. The results show that the ratio and amount of emulsifier and reactive monomer, the amount of initiator have important influence on the emulsion polymerization of acrylate monomer and its application performance.
