Embodiment 1
[0056] 1. When preparing the primer coating, add light calcium carbonate at a ratio of 25% to 75% deionized water to start the dispersing machine. During the dispersion process, add 0.6% polycarboxylate sodium salt dispersant, and then add in order after dispersing for 20 minutes. Add 6% polyvinyl acetate emulsion adhesive, 8% polyvinyl alcohol glue, and 0.3% color fixing agent Y. After adding all of them, continue stirring for 15 minutes to complete the preparation.
[0057] 2. The preparation of the top coating is to use water-based silica sol as the main body, add 12% of polyvinyl alcohol glue with a solid content of 10%, and 0.2% of color-fixing agent Y, stir well and set aside.
[0058] 3. Preparation of back-coating paint Add 3% polyvinyl alcohol to 95% deionized water, stir and disperse fully, then turn on steam and heat to gelatinize under continuous stirring state, heat gelatinization time for 30 minutes, the colloid is colorless and transparent. OK, cool to room temp...
