Development of A Dual Curing Waterborne Wood Varnish
Zhang Xingqiao;Shanghai Yuan Chemical Co.,Ltd.;
The preparation process of waterborne wood varnish that can simultaneously participate in UV curing and crosslink curing of acrylate-aziridine was introduced.The comprehensive design of the formula was carried out from the key raw material type,main emulsion proportion,UV curing conditions,curing agent addition amount,physical drying conditions and other factors.The comprehensive performance of film was characterized from the aspects of mechanical properties,chemical resistance,old coating adhesion and so on under single curing/dual curing conditions.Furthermore,in the practical application of the UV curable waterborne wood coatings,to solve that due to the abnormal structure led to the coating surface ultraviolet radiation does not fully influence the film performance and other disadvantages.
