Abstract

The invention belongs to the technical field of composition coatings and particularly relates to an antibacterial hydrophilic coating. The technical problem to be solved by the invention is to provide a coating having better antibacterial and hydrophilic effects. In order to solve the problem, according to the technical scheme, the antibacterial hydrophilic coating comprises the following components in percentage by weight: 30-50% of water-soluble acrylic resin, 3-10% of alcohols or ethers or ethers, 0.5-5% of a curing agent, 0.1-1% of a surfactant, 0.1%-1% of metals and antibacterial agents of oxides of metals and the balance of water. After a prime coating is subjected to high temperature curing and film forming, the combination of good antibacterial and hydrophilic functions is achieved.

Description

technical field [0001] The invention belongs to the technical field of combined coatings, in particular to an antibacterial hydrophilic coating. Background technique [0002] Air conditioners are household appliances used to adjust indoor air temperature and humidity, and usually require the operating environment to be kept airtight. The relevant research on air-conditioned wards in hospitals shows that, under the condition that other conditions remain unchanged, compared with before the operation of the air conditioner, the number of bacteria and fungi in the indoor air after the operation of the air conditioner increases with the prolongation of the operation time. The category includes a variety of common pathogenic bacteria: such as Staphylococcus aureus, Bacillus subtilis, Bacillus licheniformis, Pseudomonas aeruginosa (Pseudomonas aeruginosa), Staphylococcus epidermidis, Mucor and so on. In addition, the concentration of microorganisms in air-conditioned wards is 1.2 ...
