Embodiment 1
[0040] A preparation method for a single-coated UV ultraviolet photocuring color effect paint applied to a plastic base material, the method comprising the following steps:
[0041] (1) Preparation of mixture A:
[0042]
[0043] (i) Add the resin, UV monomer, and leveling agent into the small bucket first according to the formula requirements, and stir at 800-900 rpm, stir for 5-10 minutes, and keep the temperature at 30-50°C;
[0044] (2) Preparation of mixture B:
[0045]
[0046] (ii) Add pearlescent pigment, nano-color paste, photoinitiator, and photosensitizer into the large tank according to the formula requirements, stir at 800-1200 rpm for 5-10 minutes, and keep the temperature at 30-50°C;
[0047] (iii) The mixture obtained in the sampling step (ii) is tested for cleanliness, and the scraper paper is scraped with a 100um wet film preparation device, and there are no obvious particles on the scraper paper;
[0048] (iv) Add the mixture obtained in step (i) int...
Embodiment 2
[0052] (1) Preparation of mixture A:
[0053]
[0054] (i) Add the resin, UV monomer, and leveling agent into the small bucket first according to the formula requirements, and stir at 800-900 rpm for 5-10 minutes, keeping the temperature at 30-50°C;
[0055] (2) Preparation of mixture B:
[0056]
[0057] (ii) Add pearlescent pigments, colorants, photoinitiators, and photosensitizers into the vat according to the recipe requirements, stir at 800-1200 rpm for 5-10 minutes, and keep the temperature at 30-50°C;
[0058] (iii) Sampling (ii) To test the cleanliness, use a 100um wet film preparer to scrape on the scraper paper, and there are no obvious particles on the scraper paper;
[0059] (iv) Add (i) into (ii), stir at 800-900 rpm for 5-10 minutes;
[0060] (v) Sampling (iv) Check the cleanliness. After there are no obvious particles, use the Iwata #2 cup to check and adjust to the range of 9 to 10 seconds;
[0061] (vi) filter, weigh and pack.
