Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to an aqueous UV finishing paint for vacuum plating.
Background
The UV vacuum plating finish paint is positioned on the outer surface of the vacuum plating layer, plays a role in decoration and protection of the vacuum plating layer, and needs to have better storage stability, water resistance, wear resistance and other performances. In order to improve the wear resistance of UV vacuum electroplated topcoats, inorganic nanoparticle fillers are typically added to the topcoat material system. The inorganic nano particles have smaller particle size and larger specific surface energy, are easy to agglomerate in a water-based finish paint material system, have poorer compatibility with a resin matrix in the finish paint, not only can not obviously improve the wear resistance of the finish paint, but also can cause the performances of the obtained UV vacuum plating finish paint such as water resistance, storage stability, adhesive force between the finish paint and a vacuum plating layer and the like to be reduced to different degrees.
At present, commercial water-based UV finishing paint for vacuum plating is characterized in that the matrix resin in a formula is subjected to hydrophilic modification, and a hydrophilic structure is generally introduced into the matrix resin structure, so that the original lipophilic structure of the matrix resin can be damaged, and the water resistance and the adhesive force between a paint film and a vacuum plating layer are poor. Some are that amphiphilic emulsifier is added into the formula of the vacuum plating finish paint to improve the hydrophilicity of oily matrix resin, so as to obtain the water-based vacuum plating paint. The amphiphilic emulsifier adopted in the mode is a linear emulsifier with one hydrophilic end and one hydrophobic end, and the linear emulsifier can only improve the hydrophilicity of the oily matrix resin to a certain extent, but the storage stability of the obtained water-based UV vacuum plating finish paint is poor, and the water resistance of a paint film, the adhesive force between the paint film and a vacuum plating layer and the like still need to be further improved.
Aiming at the problems, the self-made modified nano aluminum oxide dispersion liquid and the amphiphilic emulsifier composition are added in the formula of the vacuum plating finish paint, and the aluminum oxide nano particles in the modified nano aluminum oxide dispersion liquid are wrapped by the emulsifier SDBS, so that the vacuum plating finish paint has good water dispersion stability, not only can obviously improve the wear resistance of the finish paint, but also is not easy to reduce other performances of the finish paint.
The self-made amphiphilic emulsifier composition contains the amphiphilic emulsifier with a three-dimensional network structure, and compared with the linear amphiphilic emulsifier, the obtained amphiphilic emulsion with the three-dimensional network structure can remarkably improve the storage stability and the water resistance of a water-based UV paint film for vacuum plating, because the amphiphilic emulsifier with the three-dimensional network structure has larger molecular weight, is not easy to migrate to the surface of the finishing paint, and also has more lipophilic anchor points, the coating property of the emulsifier with the three-dimensional network structure on matrix resin is better, the emulsifying effect is better, and the emulsion is more stable; in addition, the emulsifier with a netlike three-dimensional structure also contains structural fragments similar to the matrix resin (polyurethane acrylic resin), so that the compatibility between the emulsifier and the matrix resin is further increased, and the emulsifier is very beneficial to further improving the vacuum electroplating property, the water resistance and the storage stability of the water-based UV paint for vacuum electroplating.
