Acrylic emulsions are used in paper applications to improve physical properties. They can be used as saturants or coatings to influence strength and elongation properties, chemical, solvent and water resistance as well as the hand or stiffness of the product. 此外,丙烯酸乳液还可以为纸张赋予热稳定性和光稳定性。
Acrylic emulsions are a mixture of an acrylic polymer, water as a solvent, and chemical emulsifiers. Traditionally, acrylic emulsions have been offered at lower solids (below 50%) to offer stability and longer shelf life. That has been the case for many decades.
As technology has evolved, acrylic emulsions can have higher solid content and less solvent (water) content while maintaining stability and delivering expected performance requirements across a range of applications.这些应用包括用于砂纸、带卷和分色前蒙片以及装饰纸等应用的工程纸张涂层。在此类应用中,添加丙烯酸乳液可以使产品获得所需的机械性能。这些特性可以包括抗撕裂性、干湿强度、耐溶剂性和耐久性。
使用高固含丙烯酸乳液可以通过多种方式提高效率,并在工程纸张涂料中提供可持续性优势。水越少,活性固体含量就越高。这意味着需要运输的材料更少,需要使用的卡车也就更少,降低了运输成本并减少了CO2足迹。
从应用的角度来看,高固含丙烯酸乳液可以在一次操作中实现更高的成膜/聚合物添加量,提高了工艺效率和生产率。水更少,干燥时间和能源消耗都会减少。更高的固体含量也提高了订购效率,订购一定体积的产品需要的订购次数更少。
