摘　　要： 将马来酸酐接枝改性的氯化聚丙烯树脂(CPP-g-MAH)溶于乙酸丁酯中,再加入由Tween-20和Span-80组成的复合乳化剂进行乳化,获得了稳定的CPP-g-MAH乳液。研究了CPP-g-MAH乳液、丙烯酸复配树脂RX、乙二醇以及表面活性剂Surfynol465的用量对喷码油墨体系稳定性和墨层在聚乙烯(PE)表面附着力的影响,确定了较佳的乳化条件为:Tween-20与Span-80质量比3:2,Tween-20与Span-80的总质量为CPP-g-MAH质量的12%。较佳的水基喷码油墨配方(以质量分数表示)为:CPP-g-MAH乳液30%,水溶性丙烯酸树脂RX2%,乙二醇15%,Surfynol4651.5%。在此条件下制取的水基喷码油墨在PE表面的附着力达1.04N/mm2,非常适合于PE制品表面的喷码打印。 A stable emulsion of maleic anhydride grafted chlorinated polypropylene （CPP-g-MAH） was obtained by emulsification with a compound emulsifier consisting of Tween-20 and Span-80 in butyl acetate. The effects of the dosages of CPP-g-MAH emulsion, acrylic compound resin RX, ethylene glycol, and Surfynol 465 surfactant on the stability of the jet ink prepared therewith and the adhesion of ink to polyethylene surface were studied. The relatively good emulsification conditions were determined as follows： mass ratio of Tween-20 to Span-80 is 3 ： 2; and the mass of Tween-20 plus Span-80 equals to 12% of CPP-g-MAH. The optimal formulation for jet ink was obtained as follows： CPP-g-MAH emulsion 30wt%, water-soluble acrylic resin RX 2wt%, ethylene glycol 15wt%, and Surfyno1465 1.5wt% The water-based jet ink obtained under the above conditions has an adhesion strength as high as 1.04 N/mm2 to polyethylene surface, which is suitable for ink-jet printing on the surface of polyethylene articles.
