Embodiment 1

[0038] Weigh 63 parts of water-based polyurethane resin, place it under a disperser, weigh 27 parts of water, 9.2 parts of ethanol, 0.1 part of defoamer, 0.5 part of wetting agent, and 0.2 part of leveling agent, add it to water-based polyurethane, and stir for 1 hour. Filter and barrel.

Embodiment 2

[0040] Weigh 60 parts of water-based polyurethane resin, place it under the disperser, weigh 29.3 parts of water, 10 parts of ethanol, 0.2 part of defoamer, 0.4 part of wetting agent, and 0.1 part of leveling agent, add it to water-based polyurethane, and stir for 1 hour. Filter and barrel.

Embodiment 3

[0042] Weigh 66 parts of water-based polyurethane resin, put it under the disperser, successively weigh 26.4 parts of water, 6.8 parts of ethanol, 0.3 parts of defoamer, 0.2 parts of wetting agent, and 0.3 parts of leveling agent, add it to water-based polyurethane, and stir for 1 hour. Filter and barrel.

[0043] Coating test results: high gloss, low peel strength, no whitening, no softness, no loss of gloss at 180°C, clean appearance.

[0044] In summary, after the coating composition prepared by the present invention is coated on PET or OPP film to form a film, it is detected by the standard detection method of 3M adhesive tape, and the film is easy to completely peel off, and there will be no phenomenon of fracture, which is different from the existing Compared with technology, it has low peel strength, good temperature resistance and clean appearance.

Abstract

The invention discloses a high-gloss waterborne laser transfer coating which is characterized by comprising, by weight, 60-66% of waterborne polyurethane ester, 26.4-30% of deionized water, 6.4-10% ofethyl alcohol, 0.1-0.3% of defoaming agents, 0.2-0.5% of wetting agents and 0.1-0.3% of flatting agents. The invention further discloses a preparation method of the high-gloss waterborne laser transfer coating. The method includes the steps: (1) preparing materials: preparing materials according to the components; (2) mixing: accurately weighing the waterborne polyurethane, adding the waterbornepolyurethane intp a disperser, sequentially accurately weighing the ethyl alcohol, the defoaming agents, the wetting agents, the flatting agents and the like, adding the ethyl alcohol, the defoaming agents, the wetting agents, the flatting agents and the like into waterborne polyurethane resin, uniformly stirring the materials, filtering, and barreling the product.

Description

technical field [0001] The invention relates to a high-gloss water-based laser transfer coating and a preparation method thereof, in particular to a water-based polyurethane laser transfer coating suitable for gravure printing and offset printing and a preparation method thereof. Background technique [0002] Waterborne polyurethane uses water as the dispersion medium. It has the advantages of non-toxic, non-flammable, non-polluting, energy-saving, safe and reliable, and meets the development requirements of green industry. [0003] However, due to the incomplete research on waterborne polyurethane transfer coatings, there are still many unsatisfactory performances of waterborne polyurethane transfer coatings. The invention studies the high gloss, high temperature resistance, stripping property and the like of the waterborne polyurethane transfer coating. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior a...
