锆化合物可用作促粘剂和防粘剂,可以改善粘合剂的粘接性能,常用作聚烯烃印刷油墨的促粘剂。通过测定剥离粘合力、硝化纤维溶液粘度、表面能及X射线光电子能谱(XPS),对其机理进行了研究。锆化合物可交联含有某些官能团,如羧基、羧基的聚合物。这已经通过对乳液聚合物在水中溶胀以及干、湿材料机械性能的测试进行了研究。在废纸的回收利用中,纸上的粘合剂可能会粘在处理设备上而引起麻烦,还可能在最终制品上留下难看的斑点。解决此类问题的关键是在重新制浆过程中添加锆化合物。通过测定粘合性、渗透性以及X射线光电子能谱,对此过程进行了研究。研究表明,锆化合物影响聚合物的粘合性能仅仅是表面起作用,并非改变其性能。此表面作用可分两种类型,即羧基与锆聚合物的结合(键合)和氢键的形成。
Zirconium compounds can be used as tackifiers and release agents, can improve the adhesive properties of adhesives, often used as a polyolefin printing ink adhesion promoter. The mechanism was investigated by measuring the peel adhesion, viscosity of nitrocellulose solution, surface energy and X-ray photoelectron spectroscopy (XPS). Zirconium compounds can crosslink polymers that contain certain functional groups, such as carboxyl and carboxyl groups. This has been investigated by testing the swelling of the emulsion polymer in water and the mechanical properties of dry and wet materials. In the recycling of used paper, the adhesive on the paper may stick to the handling equipment causing troubles and may leave unsightly spots on the final product. The key to solving this problem is the addition of zirconium compounds during repulping. The process was studied by measuring the adhesion, permeability, and X-ray photoelectron spectroscopy. Studies have shown that the influence of the zirconium compound on the adhesion of the polymer is only a function of the surface and does not change its properties. This surface effect can be divided into two types, namely the combination of carboxyl and zirconium polymers (bonding) and the formation of hydrogen bonds.
