Abstract

The invention belongs to the technical field of coating preparation, and particularly relates to an ice flower crack coating and a preparation method and a curing method. The ice flower crack coating is prepared from 5 to 15 parts of six-functionality aromatic polyurethane acrylate, 15 to 30 parts of fatty acid modified epoxy acrylate, 8 to 15 parts of reactive diluent, 6 to 15 parts of benzophenone and 1 to 2 parts of active amine. When the six-functionality aromatic polyurethane acrylate, the fatty acid modified epoxy acrylate, the benzophenone and the active amine are subjected to UV curing, ice flower cracks are generated due to different shrinkage of the surface and the bottom of a coating in the stress release process. By adopting the synergistic effect of the six-functionality aromatic polyurethane acrylate, the fatty acid modified epoxy acrylate, the benzophenone and the active amine in a specific ratio, the coating with good plating property, boiling resistance, high yield and uniform ice flower crack distribution can be obtained.

Description

Technical field [0001] The present invention belongs to the preparation of coating materials, and more particularly to an ice flower crack coating and a method of preparing a method and a curing method. Background technique [0002] UV vacuum coating refers to a new type of ultraviolet cured coating developed on a UV plastic coating. With energy-saving and environmental protection concepts, the concept of production and reduction cost is getting deeper into the heart, plastic decorative technology replaces the development trend of limited metal materials. It is more obvious that a plastic product metallization decorative technology is produced. After the plastic substrate is applied, it is plated with a vacuum electroplating or splashing, painted a layer of metal film layer, and then coating the face pain. After the coated plastic surface, it is completely flashing with metal gloss, and it is worthwhile to see plastic products. [0003] Existing UV vacuum coated paint mainly used...
