Abstract
Abstract

The purpose of this paper is to study the influence of different adhesives and dosage on the performance of ink absorption coating and improve the quality of foam surface. In this experiment, silica was used as pigment, PVA1788, PVA1799, PVA235 and soluble starch were used as binders, and rigid polyurethane foam was used as coating object. In this experiment, a spraying method was used to coat the surface of plastic foam, UV printer was used for graphic output, and related equipment were used to test the performance of the coating. The results showed that when the ratio of adhesive (PVA1788) to pigment was 20%, the whiteness and wettability of the coating were the best. In this case, rich color range and gradation level could be obtained. With the increase of the alcoholysis of polyvinyl alcohol, the dissolution became difficult, water resistance increased, bonding force increased, film formation became better, and the contact angle of the coating prepared by the high alcoholysis of PVA as adhesive was lower. The coating with PVA235 as adhesive had the highest color density and the best comprehensive effect.
