| 摘要:对典型烟用商标纸和包装胶性能进行分析，研究了胶黏剂在商标纸粘合部位表面液滴的接触角和宽度的变化，探讨了上胶开放时间对商标纸包装胶组合粘合强度的影响。结果表明，包装胶滴加到商标纸表面上时，无论印刷面还是非印刷面，随着时间的延长，接触角不断减小，液滴宽度不断增加，液滴接触角和宽度达到平稳的时间不同，液滴接触角的降低是扩展和渗透共同作用的结果，而液滴宽度变化只和扩展有关。不同的商标纸-包装胶组合，液滴接触角和宽度的变化不同，上胶开放时间窗口也不同，与胶黏剂的黏度和固含量及商标纸的扩展和渗透性有一定的联系。水对商标纸的润湿性与胶黏剂明显不同，不宜采用水在纸张表面的润湿性来判断胶黏剂的行为。 |
| Abstract:On the basis of analyzing the performance of typical printed cigarette packet packaging paper and cigarette packaging adhesive， the contact angle and width changes of adhesive droplets on the surface of the adhesive area of packet packaging paper were studied， and the effect of adhesive opening time on the adhesion strength was explored. The results showed that when packaging adhesive droplets were added to the surface of packet packaging paper， whether on the printed or non-printed surface， the contact angle continued to decrease and the droplet width continued to increase over time. The time for the two to reach equilibrium was different. The decrease in droplet contact angle was the result of the joint action of expansion and penetration， while the change in droplet width was only related to expansion. Different combinations of packet packaging paper and packaging adhesive had different changes in droplet contact angle and width， as well as different opening time windows for gluing. It was related to the viscosity and solid content of the adhesive， as well as the expansion and permeability of the packet packaging paper. The wettability of water on packet packaging paper was significantly different from that of adhesives， and the wettability of water on the surface of the paper should not be used to determine the behavior of adhesives. |
