Problems solved by technology

[0003] After mixing more UVLED frosted paints on the market with water, because the UVLED frosted particles are relatively aggregated, more time and energy are required for the dispersion process, and the viscosity and rheology of the mixed UVLED frosted paints are poor, and prolonged contact In the air, the UVLED matte coating will still have mildew and deterioration.

Embodiment 1

[0016] A UVLED matte formula, comprising the following raw materials in parts by weight: 25 parts of acrylic polyurethane resin, 15 parts of acrylic polyester resin, 8 parts of photosensitizer, 11 parts of photosensitive resin, 2 parts of auxiliary agent, 0.3 part of light stabilizer, sand Powder filling 12 parts.

[0017] Among them, the additives are wetting and dispersing agents, thickeners, anti-mildew and preservatives.

[0018] After that, the following steps are carried out: A. First mix a part of acrylic acid monomer with a photosensitizer and a light stabilizer and heat to melt, wherein the temperature of mixing, heating and melting is kept below 100°C.

[0019] B. Stir with the remaining monomer and acrylic polyurethane to disperse evenly. The mixing 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, and stir and mix; the mixing speed is 7...

Abstract

The invention discloses a formula of a UVLED frosted material. The formula comprises the following raw materials in parts by weight: 20-30 parts of acrylic polyurethane resin, 10-20 parts of acrylic polyester resin, 8-10 parts of a photosensitizer, 10-12 parts of photosensitive resin, 1-3 parts of auxiliary agents, 0.3-0.5 part of a light stabilizer and 10-15 parts of a sand powder filler, whereinthe auxiliary agents comprise a wetting dispersant, a thickening agent, a mildew-proof agent, and a preservative; the preparation method is reasonable in process, compared with a UVLED frosted dispersoid on the market at present, the UVLED frosted material has better stability, and the time and energy required for completing the dispersion process can be reduced, so that the UVLED frosted material has good viscosity and rheological property, the uniform UVLED frosted coating is easy to form, and the UVLED frosted coating is not easy to mildew and deteriorate under the conditions of moisture and temperature.

Description

technical field [0001] The invention relates to the technical field of UV coatings, in particular to a formula for UV LED frosting. Background technique [0002] UV coatings refer to coatings that are cured using UV radiation. UV curable coatings can be applied to ink printing and exposed to UV radiation. Its solid content can be as high as 100%, so it has no volatile components and does not pollute the environment. The high solids content also allows it to be used in very thin films. UV-curable coatings can also be used to coat glass and plastic, wood, aluminum beverage bottles, and more. [0003] After mixing more UVLED frosted paints on the market with water, because the UVLED frosted particles are relatively aggregated, it takes more time and energy for the dispersion process, and the mixed UVLED frosted paint has poor viscosity and rheology, and it is difficult to contact for a long time. In the air, UVLED frosted coatings will also have mold and deterioration. Aim...
