摘　　要：使用共聚和交联共用的方法对汽车滤纸用醋丙乳液增强剂进行改性,研究了体系中甲基丙烯酸甲酯(MMA)、丙烯酸(AA)、N-羟甲基丙烯酰胺(NMA)和三聚氰胺甲醛树脂(MF)用量对浸渍后滤纸强度性能的影响。结果表明,在MMA用量20%(质量分数,下同)、AA用量3%、NMA用量5%、MF用量4%时,改性醋丙乳液可赋予滤纸优良的强度性能,同时保持滤纸优良的孔隙结构和透气性。Vinyl acetate/acrylic copolymer emulsion was prepared and modified with crosslinking agents. Effects of the dosage of methyl methacrylate, acrylic acid, N-methyl acrylamide and melamine formaldehyde resin on the properties of auto filter nonwovens were discussed. The result showed that when 20% MMA, 3% AA, 5% NMA and 4% MF of total monomers are used, the prepared emulsion can endow the filter with great strength properties and maintain the excellent filter properties of the auto filter nonwovens.
