Problems solved by technology

The original gift packaging is becoming more and more diversified and high-end, especially now that tactile varnish is the most popular, and now some high-end gift boxes and some jewelry boxes are coated with a layer of matte tactile varnish. High-end gift boxes and jewelry boxes are valuable souvenirs in themselves, so they also put forward strict technical requirements for water-based matte tactile varnishes. Silk has the same feel as velvet. Because its outer packaging is constantly in contact with human hands, some poor-touch varnish products will turn white after being applied. Phenomenon, what's more, after a long time of storage, yellowing will appear

Embodiment 1

[0026] Water-based varnish formula one

[0027] Waterborne polyurethane dispersion 70%;

[0028] Modified acrylic elastic emulsion 14%;

[0029] Leveling agent 3%;

[0030] Coupling agent 3%;

[0031] Hand feeling wax paste 5%;

[0032] Matting powder 2%;

[0033] Hand feeling anti-scratch agent 1%;

[0034] Defoamer 0.3%

[0035] Water 1.7%

[0036] The sum of the mass percentages of the above raw materials is 100%.

[0037] Preparation

[0038] At room temperature, first add water-based polyurethane dispersion, then add matting powder and a part of defoaming agent, disperse for about 30 minutes, and rotate at 900~1200r / min to ensure that the matting powder is completely dispersed, then reduce the speed to 600~900 r / min min, add the modified acrylic elastic emulsion, disperse evenly, and then add the hand feeling wax slurry, leveling agent, coupling agent, hand feeling anti-scratch agent and the remaining defoamer in sequence. Disperse for about 10 minutes to disper...

Abstract

The invention discloses a water-based matte touch gloss oil and a preparation method thereof. The water-based matte touch gloss oil is prepared from the following raw materials in percentage by mass: 65-80% of water-based polyurethane dispersion, 10-20% of modified acrylic elastic emulsion, 1-3% of flatting agent, 3-5% of coupling agent, 3-5% of hand touch wax slurry, 1-3% of matting agent, 0.1-0.5% of defoamer, 0.5-2% of hand touch scratch-resistant agent, and 0-3% of water. The water-based matte touch gloss oil prepared from the materials is low in matte degree, and employs water as a diluent and contains no organic solvent or heavy metal; and the water-based matte touch gloss oil is natural and soft in color and luster without whiting, and good in color reveal property. Furthermore, the water-based matte touch gloss oil is suitable for surface coating treatment of high-quality paper, so that the coated paper feels like cotton, silk and velvet, and the paper finished product is good in matte degree and high in white gasoline resistance; the level of product packaging is greatly improved; and the water-based matte touch gloss oil is mainly applied to leatherette paper, imitation leather, calendered paper and some coated paper.

Description

technical field [0001] The invention relates to the technology in the field of water-based varnish, in particular to a water-based matte touch-sensitive varnish and a preparation method thereof. Background technique [0002] In recent years, my country's economic level has developed rapidly, among which the packaging and printing industry is more prominent. It has changed from the original oil-based ink to the current water-based system. The current technological development of water-based varnish is also in line with international standards. The original gift packaging is becoming more and more diversified and high-end, especially now that tactile varnish is the most popular, and now some high-end gift boxes and some jewelry boxes are coated with a layer of matte tactile varnish. High-end gift boxes and jewelry boxes are valuable souvenirs in themselves, so they also put forward strict technical requirements for water-based matte tactile varnishes. Silk has the same feel a...
