Problems solved by technology

[0002] In daily life, we often find that there will be a lot of water droplets on the paint film formed by the paint. Because the water droplets are large, the water droplets cannot evaporate in time. Therefore, under the erosion of water droplets, the paint film will be affected. In addition, for objects that need to be sprayed with a paint film to dissipate heat, if a large number of water droplets are formed on the object and cannot be lost in time, it will not only affect the heat dissipation performance of the object, increase heat dissipation energy consumption, but also affect Lifespan of the paint film

Abstract

The invention discloses a hydrophilic antibacterial coating which is prepared from the following components in parts by weight: 32-40 parts of bisphenol F epoxy resin, 10-22 parts of methyl methacrylate, 20-25 parts of acrylic acid, 8-10 parts of acrylamide, 5-9 parts of ammonium persulfate, 4-8 parts of potassium sulphate, 8-10 parts of horseradishes, 1-2 parts of sodium chloride, 2-4 parts of sodium hydroxide, 12-15 parts of filler, 2-4 parts of a curing agent, 0.1-0.5 part of a polymerization inhibitor, 0.5-1 part of a defoaming agent, 1-2 parts of a flatting agent, 0.3-0.5 part of a thickener and 30-50 parts of deionized water. According to the coating, water on the surface is automatically paved to form a water film to run off, so that the hydrophilic property and the antibacterial property of the film are improved.

Description

technical field [0001] The present invention relates to coatings, especially hydrophilic antibacterial coatings. Background technique [0002] In daily life, we often find that there will be a lot of water droplets on the paint film formed by the paint. Because the water droplets are large, the water droplets cannot evaporate in time. Therefore, under the erosion of water droplets, the paint film will be affected. In addition, for objects that need to be sprayed with a paint film to dissipate heat, if a large number of water droplets are formed on the object and cannot be lost in time, it will not only affect the heat dissipation performance of the object, increase heat dissipation energy consumption, but also affect The life of the paint film. When using paint, the intrusion of bacteria cannot be avoided, therefore, the antibacterial performance of the paint is also very important. Contents of the invention [0003] In order to make the water on the surface spread by it...
