Abstract:In the study, decorative base paper was treated with self-emulsifying styrene acrylic emulsion (SAE) to improve the surface strength and printability. The effects of the type and viscosity of sizing liquid, the ratio of sizing liquid and SAE and the sizing dosage, and the difference between self-emulsifying SAE and commercial SAE on the treatment effect of paper were studied. The results showed that when starch was used as sizing agent starch was degraded by APS(dosage was 2.2%) and had visicosity of 70 mPa·s, the ratio of starch and SAE was 20∶1, sizing amount was 2 g/m2, the optimal treatment effect of decorative base paper was achiered, and the surface strength of the decorative base paper was improved 4.4 times as the original; the treatment effect of self-emulsifying SAE on the decorative base paper was better than commercial one.
