摘要： 选取具有不同特性的5种铝塑膜专用涂布液,测试了它们的黏度、固含量、细度、表面张力和保湿性等指标。以T02冷烫模切机为网纹涂布设备,分别将涂布液涂布在铝塑膜上,用金相显微镜观测了铝塑膜涂布前后的微观结构,用光泽测定仪测试了涂层的光泽,用平滑度仪测试了涂层的平滑度,用3M胶带测试了涂层的附着力。运用主成分分析法分析了影响涂布液性能的主要因素,确定了不同因素的影响权重系数,利用多元回归分析法建立了涂布液基本性能与涂层质量特性(光泽、平滑度、附着力)的综合评价函数模型;通过实验,验证了模型的合理性。使用该评价模型评价涂布液性能时,不需要对涂布液进行打样测试,相对于传统的评价方法具有高效和实用的特点。

Abstract: Five kinds of special coating liquids with different properties were selected for the determination of viscosity, solid content, fineness, surface tension and moisture retention.The T02 cold-press die-cutting machine was applied to coat the surface of the aluminumplastic film, and the microstructure of the aluminum-plastic film before and after coating process was observed by metallographic microscope. The gloss of coating was measured bythe gloss tester. The smoothness of the coating was measured by the smoothness analyzer. The adhesion of the coating was measured by using the 3M adhesive tape. The main factors influencing the performance of the coating liquid were analyzed by the principal component analysis method. The influence coefficients of the different factors were determined. The comprehensive evaluation function model between the basic properties and the coating quality characteristics(e.g, gloss, smoothness and adhesion ) were established by the multiple regression analysis method. The rationality of the model was verified by experiments. When the evaluation model was used to evaluate the performance of the coating solution, it was not necessary to carry out a proofing test on the coating solution, which had the advantages of high efficiency and practicality as compared with the conventional evaluation method.
