Abstract

The invention discloses a water-based pearlescent medium suitable for PVC wallpaper printing ink. The water-based pearlescent medium suitable for PVC wallpaper printing ink comprises, by mass, 40-50%of a modified waterborne polyurethane resin, 30-35% of water, 0.1-0.3% of a pH regulator, 1-2% of an antifoaming agent, 4-6% of a wetting leveling agent, 5-8% of a coalescing agent, 4-6% of a retarder, 2-3% of a surfactant and 1.2-2.5% of a thickener, the sum of the contents of all above components is 100%, the surfactant is an anionic surfactant, the main component of the anionic surfactant is sodium decyl ester sulfonate, the retarder is propylene glycol, and the pH value of the above solution is 8-10.5. The invention further provides a preparation method of the water-based pearlescent medium suitable for the PVC wallpaper printing ink. The product with a strong pearlescent effect is obtained through the above formula and the preparation method by selecting a routine common pearlescent powder without individually chemically reacting and processing the pearlescent powder raw material, so the universality and the practical quantification are effectively improved.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a water-based pearlescent medium suitable for PVC wallpaper printing ink and a preparation method thereof. Background technique [0002] Wallpaper is an inseparable decorative material for every household. It is used to beautify the wall environment of the home during home decoration. PVC wallpaper is a wallpaper made of PVC as the main component. It has a good three-dimensional effect and can produce many special patterns that cannot be achieved by pure paper. , such as: imitation wood grain, relief, imitation tiles and other effects, realistic patterns, strong three-dimensional sense, and has excellent waterproof performance, can resist the erosion of grease and moisture, especially suitable for kitchens and bathrooms. [0003] The pearlescent effect on the above-mentioned PVC wallpaper can further achieve a dazzling visual effect, which is loved by people. The pearlescent effect o...
