锆化合物能起到粘合促进剂和阻止剂的作用，它们能改进粘合剂的粘接性能．它们作为粘合促进剂应用于聚烯烃型印刷油墨．其机理已经得到研究，其方法是测量剥离强度、硝化纤维素的粘度、表面能和Ｘ－射线光电子分光仪（ＸＰＳ）测量．锆化含物能交联含有相应的功能集团的聚合物，如羰基和羟基聚合物．这些已通过乳化聚合物的在水中的溶胀测定，以及潮湿的、干燥的材料的机械测试等而被研究过．当使废纸再生时，存于纸上的粘合剂性物（称其为Ｓｔｉｃｋｉｅｓ）会带来问题，这就是粘附于加工机械上，并在产品上产生难看的斑点．本文对在废纸再生过程添加锆化合物，以减少上述问题中的第一个问题进行了探讨．进行此研究时。测量了粘合力、渗透及ＸＰＳ谱．研究表明，锆化合物与聚合物通过表面的相互作用，而影响聚合物的粘合性质，并不改变其余的性质．两种型式的相互作用被述及：羧基对锆聚合物的连接和氢键．
Zirconium compounds function as adhesion promoters and blockers, which improve the adhesive properties of the adhesive. They are used as adhesion promoters in polyolefin-type printing inks. The mechanism has been studied by measuring peel strength, viscosity of nitrocellulose, surface energy and X-ray photoelectron spectroscopy (XPS) measurements. Zirconium compounds can crosslink polymers containing the corresponding functional groups, such as carbonyls and hydroxyl polymers. These have been investigated by swelling in water of emulsified polymers, as well as mechanical testing of damp, dry materials and the like. Adhesive materials stored on paper (called stickies) pose problems when regenerating used paper, which is the problem of sticking to processing machines and producing unsightly spots on the product. In this paper, zirconium compounds are added to the paper recycling process to reduce the first of these problems. When conducting this study. Adhesion, penetration and XPS spectra were measured. It has been shown that the interaction between the zirconium compound and the polymer through the surface affects the adhesive properties of the polymer without changing the rest of the properties. Two types of interactions are described: the attachment of carboxyl-to-zirconium polymers and hydrogen bonding.
