Problems solved by technology

At present, the high-gloss coatings for vacuum aluminum-coated paper are solvent-based, alcohol-soluble, and emulsion-based coatings. Among them, solvent-based and alcohol-soluble coatings contain a large amount of organic solvents, which have a strong smell and are easy to pollute the environment.
[0004] Chinese patent (CN101250834A) discloses a kind of surface coating coating for vacuum metallized paper treatment, by adding acrylic resin, acrylate resin, neutralizing agent, leveling agent and wear-resistant agent etc. to prepare the vacuum metalized paper surface coating coating It has excellent transparency and abrasion resistance, but it needs to add anti-abrasion agent, and its storage stability is slightly poor

Abstract

The invention provides high-gloss paint for vacuum aluminized paper and a preparation method and application thereof. The high-gloss paint comprises the following components in parts by weight: 0.5-2.0 parts of hydroxyl acrylate resin, 2-10 parts of polyvinyl alcohol, 5-35 parts of acrylic resin, 0.5-15 parts of neutralizer, 100 parts of acrylate resin, 0.1-1.0 part of defoaming agent, 0.2-0.8 part of flatting agent and 500-1000 parts of water. As for the prepared high-gloss paint for treatment of vacuum aluminized paper, the solid weight content is 15-40%, and the pH value is 5-8. Besides, the high-gloss paint can effectively overcome the disadvantages of the existing process, so that the gloss, abrasive resistance and storage stability of the paint are greatly improved.

Description

technical field [0001] The invention relates to a preparation method and application of a high-gloss coating for vacuum aluminized paper. Background technique [0002] Vacuum aluminum-coated paper is mainly composed of base paper, aluminum layer and coating. It has good gloss and smoothness, good flexibility, high fastness of the aluminum sprayed layer, beautiful and environmentally friendly, and has good printing performance and machining performance. The surface strength of aluminized paper is high, it can adapt to the speed of high-speed printing machines, and can also bear the tension caused by the increase in ink viscosity, which has good adaptability to improve production efficiency and stabilize printing quality. The surface tension of aluminized paper is conducive to the transfer of ink during printing, and the printing ink film is flat, smooth, and the graphics and texts are clear and complete. Therefore, it can be widely used in the exquisite packaging of tobacco,...
