Problems solved by technology

[0002] The main binder of decorative paper ink is protein powder. In the previous production process, natural casein was always used. However, due to irresistible natural climate in recent years, the quality of casein is no longer as stable as before. The color is darker and there are more impurities, which will affect the stability of the final product quality, especially in high temperature in summer. If the room temperature exceeds 35°C, the ink tank will often appear floating color phenomenon after long-term printing, which will cause the color difference of the printed sample to increase, which will seriously affect the quality of the printed sample. quality
[0003] The casein environment-friendly water-based decorative ink currently produced by our company has mature technology and is widely used by customers. However, the quality of casein, the main raw material of decorative paper ink, is unstable, and many customers save costs by adding a large amount of water for dilution, which often leads to printing During the process, there are floating and color running phenomena, which cause problems such as large color difference and contrast in the printed sample

Abstract

The invention relates to a highly-waterproof decoration paper ink produced from plant modified proteins, and belongs to the field of furniture building materials. The highly-waterproof decoration paper ink produced from plant modified proteins comprises modified soybean resin, water, an antifoaming agent, a pigment, a polymeric dispersant, a pH regulator, a wetting agent, a slow drying agent, a bactericide and a thickener. The purpose of the invention is to break through the disadvantages of existing highly-waterproof decoration paper inks. All components of the highly-waterproof decoration paper ink produced from plant modified proteins can be directly diluted with pure water, and the dilution is easy to operate, so the use amount of a solvent is effectively reduced, thereby reducing the discharge amount of VOCs; the problem of abnormal product quality caused by unstable quality of casein is improved; and the weatherability can reach GB-T15102-2006 Standard Blue Wool Grade 6 or above, the printing color difference is small, and the quality of printed samples is significantly improved.
