Abstract

The invention provides a medical smell-removing antibacterial coating which is characterized by comprising the following components in percentage by weight: 20-30% of water, 40-55% of acrylic resin, 0-5.5% of water-based pigment, 0.7-2% of a coalescing agent, 0.4-1.25% of a dispersant, 0.15-0.5% of a leveling agent, 0.05-0.1% of a defoaming agent, 2-3.35% of a water-based adhesion accelerant, 5-7.65% of a negative ion additive, 0.22-1.38% of sodium hydrogen carbonate and 5-12.5% of nano silver. The medical smell-removing antibacterial coating is suitable for medical wall surfaces, has good peculiar smell removing ability and antibacterial property, can effectively kill bacteria and viruses and prevent the propagation of the bacteria and viruses, is good in adhesive powder, and is environmentally friendly and low in toxicity.

Description

technical field [0001] The invention relates to a medical odor-removing and antibacterial coating and a preparation method thereof. Background technique [0002] In modern life, bacteria and germs are easy to breed and exist in various environments, especially in the more complicated environment of hospitals, where various bacteria and viruses are prone to cross-infection, which has caused great harm to the health and safety of patients, family members and staff. threaten. Moreover, various liquid medicines and secretions in the hospital have a strong smell, are not easy to volatilize, and easily cause people's discomfort. [0003] The use of traditional solvent-based coatings is increasingly restricted due to their high levels of volatile organic compounds (VOCs) and harmful air pollutants. Therefore, pollution-free water-based coatings are attracting more and more attention. Water-based paint is a relatively new type of paint in the paint market. Compared with tradition...
