Description
Technical field
The present invention relates to a kind of coating of chemical field, particularly the anti-scratch matte varnish of a kind of UV.
Background technology
UV paint is photo-cured coating, and it is the furniture lacquer more widely of application at present, and principal feature has: through intensive ultraviolet photocuring, process, color and luster is stable, for a long time Chang Xin.So be widely used at aspects such as office furniture, be employed in big area office furniture in recent years.But general UV paint is in this large finish paint spraying situation, and levelling property and gloss homogeneity all do not reach market demands, and traditional way is to spray PU finish paint with UV priming paint again.Cause like this operation to increase, lengthen man-hour, uses PU paint, a large amount of organic solvent pollution atmosphere of release, and whole efficiency and benefit are not high, have reduced the whole efficiency of application.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of big area that is suitable for to spray paint, and good leveling property, gloss good uniformity, UV matte varnish that wear resistance is good.
Technical problem to be solved by this invention is achieved by the following technical programs:
