Problems solved by technology

[0002] As a green printing material, water-based transparent ink has developed rapidly in recent years and is widely used in packaging and printing of electronic consumer goods, pharmaceutical packaging, cosmetics packaging and other high-quality packaging and printing. However, due to the lack of film density and compactness of water-based transparent ink High, water-based transparent ink is easy to be scratched and scratched after forming a film, and there are defects such as scratches and scratches after the follow-up bronzing, die-cutting, bonding and other processes of fine packaging printing, resulting in defective products
This is also a common shortcoming of water-based transparent inks, which greatly plagues the printing industry and seriously affects the application of water-based transparent inks in packaging printing.
[0003] Development of high-scratch-resistant water-based transparent ink component composition: At present, water-based acrylic resin is generally used as film-forming resin in water-based transparent inks. Pure acrylic resin has less side branches and low self-crosslinking reactivity. Insufficient compactness and hardness, water-based transparent ink is easy to scratch and not wear-resistant after curing into a film
In the prior art, there are a large number of literatures on the scratch resistance and scratch resistance of ink film formation, but it is still difficult to meet the requirements of ink for high scratch resistance and scratch resistance

Embodiment 1

[0030] The smooth and scratch-resistant water-based varnish is prepared from the following components in parts by weight: 20% multifunctional styrene-acrylic acid copolymer soft emulsion, 34.5% styrene-acrylic acid copolymer hard emulsion, 30% High molecular weight solid acrylic resin 20%, water-based defoamer 0.3%, leveling agent 0.3%, 25% ammonia water 3%, dimethylethanolamine 1.0%, slip agent 0.3%, wax emulsion 8.0%, active amine 6.0%, Gas-phase nano silicon dioxide 0.6%, film-forming aid 1.5%, deionized water 4.0%, ethanol 0.5%. According to the ratio of the above components, first add high molecular weight solid acrylic resin, deionized water and defoamer into the container, stir in a high-speed stirring disperser with a speed of 400-1500 rpm, and slowly divide it into three times during the stirring process. Add ammonia water, add once every 20 minutes, stir for 2-8 hours until the solid resin is completely dissolved, then add the remaining components into the dissolved ...
