Abstract

The invention belongs to the field of ultraviolet-curable coatings, and discloses an ultraviolet-curable coating with oxygen inhibition resistance, and a preparation method thereof. The ultraviolet-curable coating with oxygen inhibition resistance is prepared from, by weight, 70-80 parts of acrylic resin, 20-30 parts of an active diluent, 1-3 parts of a photoinitiator and 2-15 parts of mercapto-terminated hyperbranched polyester. The coating has the advantages of high-efficiency energy saving and environmental protection, obtaining of a coating layer through one-time ultraviolet curing, double bond conversion rate reaching 80-95%, and substantial oxygen inhibition resistance.

Description

technical field

[0001] The invention belongs to the field of ultraviolet curing coatings, and in particular relates to an ultraviolet curing coating with an anti-oxygen resistance effect and a preparation method thereof. Background technique

[0002] UV curing technology is a high-efficiency, energy-saving and environmentally friendly new technology. Since the German Bayer company developed the first generation of UV-curing coatings in the 1960s, it has maintained rapid development and has been widely used in coatings and inks. , adhesives, printed circuit boards, information technology and biomedicine and many other fields.

[0003] UV-curable coatings develop most rapidly and are widely used in many fields such as construction, furniture, and automobiles. However, in the actual application process, acrylate UV-curable coatings often have the phenomenon that the surface is not dry or white layering appears on the surface. This is mainly due to the effect of oxygen inhibit...
