Abstract

The invention discloses an ultraviolet curable coating for low energy curing and a preparation method of the ultraviolet curable coating. The ultraviolet curable coating consists of the following raw materials in percentage by weight: 25-30% of modified polyfunctionality polyester acrylic ester, 10-15% of modified epoxy acrylate, 20-25% of modified pentaerythritol acrylic ester, 15-20% of TPGDA, 0.3-1.0% of a wetting dispersant, 10-15% of transparent talcum powder, 2-4% of a photoinitiator 1, 1-3% of a photoinitiator 2, 2-4% of a photoinitiator 3 and 0.3-0.5% of a leveling agent. The preparation method comprises the following steps: mixing the modified polyfunctionality polyester acrylic ester, modified epoxy acrylate, modified pentaerythritol acrylic ester and TPGDA, stirring to disperse, further adding the photoinitiators 1, 2 and 3 and the wetting dispersant, feeding the transparent talcum powder, and dispersing, thereby obtaining a product coating. An expected curing degree can be achieved for the ultraviolet curable coating disclosed by the invention by virtue of 40-80mj / m<2> of ultraviolet energy, so that the energy for curing a coating is greatly reduced, the construction efficiency can be improved, and the probability of quality defects on the backlight side of an irregular workpiece can be reduced.

Description

technical field [0001] The content of the present invention relates to the field of ultraviolet light curing materials, in particular to the technology of ultraviolet light curing wood paint, especially to a kind of low ultraviolet light energy curing wood paint and its preparation method. Background technique [0002] Traditional wood coatings mainly include oily coatings such as polyurethane coatings (PU), polyester coatings (PE) and nitro coatings (NC). With the continuous innovation of coating industry technology, ultraviolet (UV) curing coatings and water-based coatings have been developed after the above-mentioned traditional oil-based coatings, especially the application range of UV-curing coatings is becoming wider and wider. UV coatings have significant characteristics such as high solid content, fast curing, low emission, less pollution, assembly line production, and excellent paint film performance. Therefore, it has developed rapidly in my country in only a few d...
