Abstract


With the enhanced awareness of environmental protection , packaging and commercial printing and other aspects of environmental requirements and constraints , water-based varnish such pollution, pollution-free \priorities, countries compete to develop printed glazing material that is printed glazing technology development . But the water-based varnish scratch resistance compared to solvent-based varnish , UV varnish there is a gap , which restricts the water-based varnish in some areas for further application . This thesis is based on the status of domestic water-based varnish , developed a color card for paper printing materials such as high scratch resistance of water-based varnish . Thesis of an important component of water-based varnish - resin and additives for water-based varnish type and amount of viscosity, adhesion , gloss and abrasion resistance and scratch resistance were investigated , using principles of experimental design formula , water-based varnish formulations designed to determine the optimum ratio of the mixed resin to optimize the best water-based varnish formulations prepared with good scratch resistance of water-based varnish . The results show that the resin , the pH and moisture content that affect the viscosity of water-based varnish major factor . Prepared using high viscosity of the aqueous resin varnish viscosity, increase the pH of the system will cause an increase in the viscosity of water-based varnish , pH value is maintained between 8.0 and 9.5 , the best performance water-based varnish ; aqueous varnish with focus depending on the resin , the amount of adhesion promoter can be added to further improve the adhesion of water-based varnish ; resin determines the water-based varnish scratch resistance and abrasion resistance, adding the appropriate amount of water-based varnish wax emulsions can to some extent, improve the scratch resistance of the coating and abrasion resistance, wax emulsions and leveling agent added water-based varnish leveling have a greater impact ; impact waterborne gloss resin and the main factors leveling agent, by adding the appropriate amount of leveling agent may be improved to some extent water-based varnish gloss.
