Abstract
The invention belongs to the technical field of coating preparation, and in particular relates to an ice crack coating, a preparation method and a curing method. The ice crack paint includes 5-15 parts of six-functional aromatic polyurethane acrylate, 15-30 parts of fatty acid modified epoxy acrylate, 8-15 parts of reactive diluent, 6-15 parts of benzophenone and 1-2 parts active amine. When the hexafunctional aromatic urethane acrylate, fatty acid modified epoxy acrylate, benzophenone and active amine of the present invention are UV cured, ice cracks are generated due to different shrinkage of the surface and bottom of the coating during the stress release process. The invention adopts the synergistic effect between hexafunctional aromatic urethane acrylate, fatty acid modified epoxy acrylate, benzophenone and active amine in a specific ratio, and can obtain good plating performance, water boiling resistance, high yield, Coating with evenly distributed ice cracks.
Description
Technical field [0001] FIELD The present invention belongs to the technical preparation of coatings, in particular to a method of preparing coatings and cracks Ice and solidification methods. Background technique [0002] UV vacuum coating means coating developed on the basis of UV plastic coatings on a new UV-curable coatings, as well as energy saving ideas concepts of production cost reduction is becoming increasingly popular decorative plastics technology instead of a metallic material limited Trend even more significantly, a plastic article decorated metal ensuing technology, it is the use of a plastic substrate after priming, by vacuum plating or sputtering, a metal thin film layer coating, and then topcoated made. After coating the plastic surface, completely metallic luster flashing, do not see a plastic article. [0003] UV lacquer conventional vacuum coating, mainly used in some plastics, metals, glass and other equipment, are rendered smooth mirror effect, play a role w...
