摘要：以端羟基聚丁二烯（HTPB）、聚己二酸新戊二醇酯（PNA）、异佛尔酮二异氰酸酯（IPDI）为主要原料制
备了一系列水性聚氨酯乳液。采用 FTIR、XRD、SEM 对胶膜的结构及形貌进行了表征，对乳液性能、胶膜的
吸水率、力学性能及胶膜在双向拉伸聚丙烯（BOPP）薄膜上的剥离强度进行了测试，通过胶膜与水、乙二醇、
二碘甲烷的接触角测试计算了胶膜的表面能。结果表明，随着 HTPB 含量的增加，乳液粒径逐渐增大、胶膜表
面能大致呈逐渐减小趋势。当 HTPB 含量为 PNA 物质的量的 30%时，水性聚氨酯乳液综合性能最好，平均粒径

为 287.3 nm，胶膜表面能为 31.77 mJ/m ，拉伸强度为 14.20 MPa，断裂伸长率为 977.72%，在 BOPP 薄膜上的
剥离强度为 4.4 N/25 mm。以该乳液配制的油墨满足 GB/T 26394—2011《水性薄膜凹印复合油墨》对油墨黏度
13~50 s 的要求，且具有良好的初干性和抗粘连性，可满足日常使用。

Abstract: A series of waterborne polyurethane emulsions were prepared using hydroxyl-terminated
polybutadiene (HTPB), poly (neopentyl glycol adipate) and isophorone diisocyanate as main raw materials.
The structure and morphology of the films were characterized by FTIR, XRD and SEM. The properties of
emulsion, water absorption, mechanical properties and peel strength of films on biaxial tensile
polypropylene (BOPP) film were tested. The surface energy of the films was calculated by measuring the
contact angle between the film and water, ethylene glycol and methane diiodide. The results showed that
with the increase of HTPB content, the particle size of emulsion gradually increased, and the surface energy
gradually decreased to unchanged. When the content of HTPB was 30% of the molar amount of substance
of PNA, the prepared waterborne polyurethane emulsion had the best comprehensive performance, the
2
average particle size was 287.3 nm, the surface energy was 31.77 mJ/m , the tensile strength was 14.20
MPa, the elongation at break was 977.72%, and the peel strength on BOPP film was 4.4 N/25 mm. The ink
prepared by the emulsion met the requirements for ink viscosity of 13~50 s of GB/T 26394—2011
water-based gravure lamination ink for film, and had good initial drying and adhesion resistance, which
could meet the daily use.
