Environment-friendly coating for metal foil, as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of coatings, and particularly relates to an environment-friendly coating for a metal foil, as well as a preparation method and application thereof. The environment-friendly coating for the metal foil is prepared from a water-based resin, deionized water, a defoaming agent, a wetting agent, a thickening agent, an antioxidant, a coalescing agent, a sterilizing agent and a mildew preventive. The preparation method comprises the steps of (1) putting the water-based resin into a reaction cylinder, stirring and adding the wetting agent and the defoaming agent at the same time, and uniformly dispersing to obtain a mixed liquor A; (2) adding the deionized water, the coalescing agent, the thickening agent, the antioxidant, the sterilizing agent and the mildew preventive into the mixed liquor A, and stirring to obtain the environment-friendly coating. The coating is applied to a surface of a metal paint. According to the coating provided by the invention, the water-based resin and the deionized water are used, so that the coating is environmentally-friendly, and a fire hazard is completely avoided; the preparation method is simple in process and easy to operate; the prepared coating is good in consistency and low in preparation cost; the coating is convenient to use, high in adhesive force when being applied to a surface of the metal foil, andhigh in hardness after forming a film.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environment-friendly coating for metal foils and a preparation method and application thereof. Background technique [0002] At present, more and more mirror frames, picture frames, and furniture products on the market will be laminated with metal foil. In order to maintain the gloss and color of the metal foil for a longer period of time, transparent varnish will be coated on the gold foil. At present, metal foil products The paints used for surface coating are all solvent-based, which will generate a large amount of VOC, which not only has great damage to the environment, but also has great harm to the health of construction workers, and there is a great fire hazard. Therefore, it is urgent to develop an environmentally friendly alternative product. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the...
