Example Embodiment
[0015] Example 1
[0016] A UVLED frosted formula, including the following parts by weight of raw materials: 25 parts of acrylic polyurethane resin, 15 parts of acrylic polyester resin, 8 parts of photosensitizer, 11 parts of photosensitive resin, 2 parts of additives, 0.3 parts of light stabilizer, sand 12 parts of powder filler.
[0017] Among them, the additives are wetting and dispersing agents, thickening agents, anti-mold and preservatives.
[0018] Then proceed to the following steps: A. First, use a part of the acrylic monomer, the photosensitizer, and the photostabilizer to be mixed and heated to melt, and the temperature of the mixing and heating to melt is kept below 100°C.
[0019] B. Stir the remaining monomers and acrylic polyurethane to disperse evenly. The stirring speed is 700r / min and the stirring time is 15min.
[0020] C. Mix A and B together and stir evenly until the temperature is below 60°C, then add sand powder filler and additives to stir and mix; the stirring ...
