Example Embodiment

[0051] Example 1:

[0052] Add 10g of deionized water and 10g of water-soluble solid acrylic resin into the dispersion tank, add ammonia while stirring

[0053] 6g, after the addition, disperse for 2 hours until the water-soluble solid acrylic resin is completely dissolved; add 40g of water-based acrylic emulsion with high glass transition temperature of 90℃ and water-based acrylic emulsion with low glass transition temperature of 20℃ to the above-mentioned dissolved solution. 26g, water-based palm wax 2644 15g, BYK333 1g, WDF-568 0.1g, and urethane acrylate 2.2g, after adding, stir for 30min until completely uniform; sampling and testing PH value is 8.0, testing viscosity is 25℃ coated 4 # The cup is 58 seconds, and then the solid content is checked. A sample of 1 gram is dried at 120°C for 1.5 hours. The dry film weight is weighed as 0.395g, and the solid content is calculated to be 39.5%. The test is qualified, filtered and packaged with a 120 mesh filter bag That's it.

Example Embodiment

[0054] Example 2:

[0055] Add 10g of deionized water and 10g of water-soluble solid acrylic resin into the dispersion tank, add ammonia while stirring

[0056] 2g, after adding, disperse for 3 hours until the water-soluble solid acrylic resin is completely dissolved; add 60g of water-based acrylic emulsion with high glass transition temperature of 80℃ and water-based acrylic emulsion with low glass transition temperature of 10℃ to the above-mentioned dissolved solution. 21g, water-based palm wax 2644 10g, BYK333 0.5g, WDF-568 1g and urethane acrylate 1.5g, after adding, stir for 45min until completely uniform; sample and check PH value is 8.2, check viscosity, adjust with thickener 2g, Apply 4 for 25℃ # Cup for 50 seconds, then check the solid content, take a sample of 2 g and dry it at 120°C for 1.5 hours, measure the dry film weight to be 0.800g, calculate the solid content to be 40%, and pass the test. Use a 120 mesh filter bag to filter and pack. .

Example Embodiment

[0057] Example 3:

[0058] Add 20g of deionized water and 15g of water-soluble solid acrylic resin into the dispersion tank, add ammonia while stirring

[0059] 10g, after adding, disperse for 2.5 hours until the water-soluble solid acrylic resin is completely dissolved; add 50g of water-based acrylic emulsion with high glass transition temperature of 90℃ and water-based acrylic emulsion with low glass transition temperature of 30℃ to the above-mentioned dissolved solution. 32g, 12g of water-based palm wax, 1.5g of BYK333, 0.5g of defoamer and 1g of thickening agent, after adding, stir for 60min until completely uniform; sampling and testing PH value of 7.8, testing viscosity, using 1g thickener to adjust, 25℃ coating # 4 cups for 47 seconds, then check the solid content, take a sample of 2 grams and dry at 120°C for 1.5 hours, the dry film weight is 0.806g, the solid content is 40.3%, the test is qualified, and the 200 mesh filter bag is used to filter and pack. .

Abstract

The invention discloses a high gloss and high abrasion resistant water-based overprinting varnish and a preparation method thereof. The overprinting varnish comprises the following components: deionized water, water-soluble solid acrylic resin, non film-forming material, film material, ammonia water, water-soluble emulsion wax, wetting and leveling agent, defoaming agent and thickener. The overprinting varnish of the invention uses water as solvent; when the overprinting varnish is used, only water is volatilized, thus the overprinting varnish is environmentally friendly; and the overprinting varnish does not contain heavy metals and can pass through the volatile organic compound (VOC) detection, thus being a safe and green product. The product of the invention uses water-soluble acrylic emulsion as the main matrix which combines with water-soluble solid acrylic resin, thus the safety and environmental friend of the product can be further ensured; and by adopting the special raw material combination, the product has good printing and glazing effects, high transparency and lustrousness and excellent wear resistance and is color-fast and scratch resistant; and after printed and glazed, the product has good water resistance and is not easy to scratch.

Description

Technical field [0001] The invention involves the field of printing and packaging materials.Specifically, it involves paper printing and used for glowing, improving paper printing [0002] A high -gloss, high -wear -resistant water -resistant light oil. Background technique [0003] In today's printing and packaging industry, people pay more and more attention to the perfection of packaging. Most of the paper after printing is more than one layer. [0004] Global oil is used to improve the gloss of the paper and prevent the coloring of coloring.At present, water -based covered oil is used in the market, [0005] UV covering light oil, alcohol -soluble light oil and oil -based cover oil, and some use composite BOPP membranes.The market analysis of these light products is as follows: [0006] UV cover light oil: It is mainly composed of epoxy acrylic, active diluent, light cause, anti -foaming agent, flowing agent, etc. Diluted with a small amount of alcohol when on -board, and is ...
