Application of oxidized polyethylene wax emulsion in water-based varnish and printing ink

The oxidized polyethylene wax emulsion is roughly evenly dispersed in the system. After application, the distribution of wax particles has a glossy film surface after the dry paint film impacts the surface, and Because of the particle size distribution of different types of wax additives, when carried out, it will produce different degrees of diffuse reflection after light irradiation, which will have different effects on the gloss of the coating film. Because the current styles of wood are different, the pursuit of high gloss or matte still needs a certain anti-skid effect, and the appropriate wax emulsion should be selected according to specific needs.

  Polyethylene wax emulsion

1. Oxidized polyethylene wax emulsion can significantly improve the gloss of the coating. The abrasion resistance is obviously improved. The effect of the particle size of the emulsion on the gloss of the coating is that the wavelength of visible light is 400-700nm. When the particle size of the oxidized polyethylene wax emulsion is less than 1/2 of the wavelength of visible light, that is, 200nm, light diffraction will occur. This increases the gloss of the coating. It is generally believed that the greater the particle size change of the wax emulsion, the more obvious its gloss effect; in addition, there is a certain relationship between the gloss of the coating and the crystallinity of the wax. The particle size of oxidized polyethylene wax emulsion has reached the nanometer level, and it is a good surface protective agent for high-gloss ink systems.

Second, the oxidized polyethylene wax emulsion can provide high slip, certain wear resistance and scratch resistance? The use of oxidized polyethylene wax emulsion can not only improve the paint scratch resistance of the film, and can affect the adhesion and gloss of the paint film. The surface of the coating film can be dispersed evenly, similar to the formation of a wax protective film on the coating film, and the friction coefficient is thus reduced; this can improve the friction resistance of the coating, improve the slipperiness and scratch resistance.
