Protective layer coating for cold wave printing film as well as preparation method and use method of protective layer coating

Abstract

The invention provides a protective layer coating for a cold wave printing film as well as a preparation method and a use method of the protective layer coating. The protective layer coating is prepared from the following components in parts by weight: 10-20 parts of acrylic resin liquid, 6-12 parts of polyester type polyurethane resin, 3-5 parts of carboxyl ternary vinyl chloride-vinyl acetate resin, 3-5 parts of hydroxyl ternary vinyl chloride-vinyl acetate resin, 2-5 parts of fumed silica, 60-80 parts of ethyl acetate, 10-20 parts of methyl acetate, 6-18 parts of butanone and 0.1-0.3 part of dispersing agent. When the protective layer coating for a cold wave printing film is used for preparing a cold wave printing film, the surface of the film layer is fine, uniform and free of after-tack, the high-temperature and high-humidity resistance is excellent, and the stability is high; the adhesive force on an aluminized layer and a UV cold wave adhesive layer is strong, the fastness is good, the trimmed edges are tidy, the details are clear, and the cold wave requirements of pretreated or untreated non-shrink paper are met; and a cold wave product has unique metallic luster and has the effects of large field and small fineness, and the production process and the product are low in VOCs.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a protective coating and a preparation method and a use method thereof, in particular to a protective coating for a cold stamping film and a preparation method and a usage method thereof. Background technique [0002] With the advancement of science and technology and people's continuous pursuit of environmentally friendly products and even environmentally friendly production, cold stamping technology has received more and more attention and development due to its unique advantages. The breakthrough of cold stamping technology has benefited from the high-tech of European and American industries. The current cold stamping technology is different from the traditional hot stamping technology that relies on hot pressing to transfer electrochemical aluminum foil. It uses a new technology of cold pressing to transfer electrochemical aluminum foil. Now it has been widely used For a varie...

Problems solved by technology

However, it uses a solvent-based protective glue, which uses esters, ketones, toluene, dimethyl carbonate, methylcyclohexane, etc. as solvents, and contains solvents such as toluene and methyl ethyl ketone, which are harmful to the health of operators. It will have a certain impact, and the environmental protection type is not good; at the same time, it uses acrylic resins such as Bolier MB-12 and DSM B-811 as the main functional components, which are imported resins, and the cost is high
