Problems solved by technology

Water-based varnish is a new type of printing and varnish material that developed countries have been researching and developing in recent years. It has been increasingly valued by the printing industry. As a new green and environmentally friendly printing material, its environmental protection and safety are self-evident. It is the most environmentally friendly and energy-saving of the above varnish products, but water-based products are not as good as other products due to gloss and friction, so it is not easy to promote and apply in the market. Therefore, it is necessary to increase its research and development efforts and improve the quality of water-based varnish products. The key to developing the water-based product market, responding to the national environmental protection policy and benefiting personal safety

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 ...
