Abstract

Conventional aqueous UV varnish coatings applied to glass surfaces have poor water resistance. In view of the above problems, the present invention provides an aqueous UV glass transparent varnish, which has a large amount of hydrophobic isobornyl ester structural fragments introduced into a urethane acrylate molecular structure, and is used as a main resin component in an aqueous UV varnish system, thereby significantly improving the water resistance of an aqueous UV varnish coating layer.
Description
Technical Field
The invention relates to the technical field of coatings, and particularly relates to water-based UV glass transparent gloss oil.
Background
With the higher and higher environmental protection requirements of society, the water-based UV coating becomes the development trend of the coating field at present. The water is used for replacing an organic solvent, so that the discharge amount of VOC can be obviously reduced, and the pollution and damage to the atmospheric environment are reduced.
However, the aqueous UV coating system usually selects a host resin containing a large amount of hydrophilic groups, so that the resulting aqueous UV varnish coating layer has poor water resistance. Likewise, conventional aqueous UV varnish coatings applied to glass surfaces are also less water resistant. Meanwhile, the surface of the glass is very smooth, and the adhesion of the conventional water-based UV gloss oil coating on the surface of the glass is not good.
According to the invention, experiments show that not only can the water resistance of the water-based UV gloss oil coating be obviously improved, but also the adhesive force of the water-based UV gloss oil on the glass surface can be obviously improved by introducing the isobornyl ester segment and the bisphenol A segment into the molecular structure of the urethane acrylate.
