Abstract

The invention discloses a waterproof and antibacterial coating. The coating is prepared from components in parts by mass as follows: 45-60 parts of acrylic resin, 20-30 parts of polyvinyl alcohol, 10-15 parts of isopropanol, 1-3 parts of maleic anhydride, 10-15 parts of silicon dioxide, 3-8 parts of titanium dioxide, 2-8 parts of glycol, 30-50 parts of filler, 3-8 parts of a dispersing agent, 1-2 parts of a defoaming agent, 1-3 parts of a pigment and 10-30 parts of water. The coating has excellent waterproof and antibacterial effects, has the large adhesive force, is abrasion-resistant, ageing-resistant and long in service life and can inhibit breeding of bacteria.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof and antibacterial coating. Background technique [0002] The waterproof layer of the wall and roof is exposed to the nature, exposed to the sun, blown by strong wind, eroded by rain and snow, and the temperature changes in the four seasons. Without excellent material properties and perennial maintenance measures, it is difficult to achieve the required durability. In addition, there are many kinds of buildings built in moist soil or soaked in water all the year round, which require waterproof and antibacterial surface treatment. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a waterproof and antibacterial coating with excellent performance. [0004] In order to solve the problems of the technologies described above, a technical solution adopted in the present invention is: [0005] A waterproof and antibacterial coati...
