Problems solved by technology

However, in the daily indoor environment, the silver ion layer will turn yellow and brown in about three months.
After the silver ion layer changes color, it not only affects the appearance, but more importantly, the antibacterial performance of the silver ion layer is greatly reduced.

Abstract

The invention aims to an antimicrobial environment-friendly transparent nitro bright finish coat and a preparation method thereof. The finish coat is prepared from a main paint and a diluter in a weight ratio of 1:(0.5-1); and the main paint is prepared from the following raw materials in parts by weight: 10-30 parts of synthetic fatty acid resin, 5-10 parts of aldehyde ketone resin solution with the solid content of 60-80%, 40-60 parts of nitrocellulose, 3-5 parts of environment-friendly plasticizer, 0.1-1 part of defoaming agent, 0.5-2 parts of leveling agent, 0.2-1 part of wetting agent, 0.2-0.5 part of ultraviolet absorbent, 0.2-0.5 part of antioxidant, 0.5-1 part of high-oxidation-state nano silver ion solution and 10-20 parts of environment-friendly mixed solvent. The finish coat can form a non-toxic harmless high-oxidation-state activated complex silver ion bactericidal coating on the film surface, thereby effectively killing the harmful bacteria and protecting the good health. The finish coat has the advantages of excellent yellowing resistance, high bactericidal efficiency and long duration time.

Description

technical field [0001] The invention relates to a nitro bright finish paint and a preparation method thereof, in particular to an antibacterial and environment-friendly transparent nitro bright finish paint and a preparation method thereof. Background technique [0002] Adding inorganic silver-based antibacterial agents in the production process of coatings can form an effective bactericidal protective layer on the surface of the coated object after coating, prevent secondary pollution, and achieve the purpose of health and environmental protection. However, in the daily indoor environment, the silver ion layer will turn yellow and brown in about three months. After the silver ion layer changes color, it not only affects the appearance, but more importantly, the antibacterial performance of the silver ion layer is greatly reduced. This is due to the high activity of silver ions in silver-based antibacterial agents and the relatively active chemical properties of silver ions...
