Abstract

The invention discloses a UV photocuring coating containing a perfluoropolyether modified additive as well as a preparation method and an application of the UV photocuring coating. The UV photocuringcoating is prepared from 100 parts by mass of polyfunctional acrylate resin as main resin by being mixed with 0.5-8 parts by mass of the perfluoropolyether modified urethane acrylate additive, 1-5 parts by mass of a photoinitiator and 200-500 parts by mass of a solvent. The coating formed after UV photocuring has excellent properties of good transparency, hydrophobic angle larger than 105 degrees,resistance to marker pen scribble, acid, gasoline, wear and weather and the like. Mechanical properties of the coating are improved by the acrylate resin with higher functionality; the perfluoropolyether modified urethane acrylate additive is prepared from urethane acrylate modified with perfluoropolyether acrylate, and oil stain resistance and solvent resistance of the coating are enhanced.

Description

technical field [0001] The invention relates to a UV photocuring coating containing a perfluoropolyether modified auxiliary agent and its preparation method and application, in particular to an acrylate composition UV photocurable containing a perfluoropolyether modified polyurethane acrylate auxiliary agent The coating and its preparation method and application belong to the field of polymer materials. Background technique [0002] UV light-curing coating is a new type of coating that uses ultraviolet light as the curing energy and can quickly solidify and form a film on substrates such as paper, plastic, leather, and glass products without heating. Due to the characteristics of short curing time (a fraction of a second to a few minutes), low curing temperature, low volatile matter, energy saving, resource saving, pollution-free and high efficiency, UV light-curing coatings have a huge market prospect. At present, with the increasing application range of UV light-curing co...
