Problems solved by technology

[0004] Most of the laser anodized aluminum coatings used in this field are solvent-based. Although the production process is mature and the performance is stable, the solvents used are mostly benzene solvents, which not only cause environmental pollution, but also seriously damage the health of workers.

Abstract

The invention provides a water-based laser alumite coating without a release layer and a preparation method thereof. The coating comprises 20-30% of acrylic emulsion, 10-30% of polyurethane emulsion, 2-10% of water-soluble cellulose, 0.001-0.05% of defoaming agent, 0.01-0.2% of die pressing assistant, 0.01-0.5% of wetting leveling agent, 15-30% of deionized water and 15-30% of ethyl alcohol. The water-based laser alumite coating is environmentally friendly, low in cost and excellent in performance; it can be guaranteed that alumite has good slitting performance and a high hot stamping speed just by coating a base film with the water-based laser alumite coating directly, so that the technological process of release layer coating is simplified, the cost is lowered to some degree, and resources are saved to some degree.

Description

technical field [0001] The invention relates to a water-based laser anodized aluminum coating without a release layer and a preparation method thereof. Background technique [0002] Anodized aluminum hot stamping is a special printing process without ink. It uses a certain pressure and temperature to use the template installed on the hot stamping machine to make the printed matter and the hot stamping foil press each other in a short time, and the metal foil or The pigment foil is transferred to the surface of the hot-printed product according to the image and text of the hot-stamping stencil to form a special metallic effect. [0003] In the packaging industry, the hot stamping technology of anodized aluminum is changing with each passing day. With the rapid development of social economy and the rapid improvement of living standards, people pay more and more attention to the aesthetics of packaging materials, and the grade of packaging and decoration is getting higher and h...
