Polyethylene wax is used in the adhesive ink industry. With the rapid development of the packaging and decoration industry, the printing industry continues to put forward new requirements for printing inks, such as the printing of medicine boxes, cigarette packages, wine boxes, etc., in Higher requirements have been put forward in terms of friction resistance. In order to meet user needs, the friction resistance of ink must be improved.
Polyethylene wax has stable chemical properties, smooth hand feel, good wear resistance and high hardness. Different adding methods can give the system different gloss changes. Therefore, it is widely used in ink, coating and other industries as a dispersant, anti-wear agent, brightener, matting agent, slip agent, etc.
The addition of polyethylene wax to ink is generally done in the following ways:
1. Disperse it in organic solution to make wax slurry and apply it in solvent system.
2. Disperse in water system to make wax dispersion or wax emulsion, and apply it in water system.
3. Make micron powder with appropriate particle size and add it directly to the ink for use. In recent years, as environmental protection requirements have penetrated into every aspect of social life, water-based ink has developed rapidly. As an important additive for water-based inks, wax emulsions have increasingly higher performance requirements.
After the wax emulsion is added to the ink, the wax drifts to the surface of the coating film during the film formation process and is evenly dispersed, so that the top layer of the coating film is protected by wax, showing the characteristics of wax. Due to its role in controlling the friction coefficient, it has The smoothness, wear resistance, and scratch resistance of the coating have an impact.
