Abstract

The invention provides an environment-friendly waterproof antibacterial coating and a preparation method thereof. The coating is prepared from the components of organosilicon-modified epoxy resin, bisphenol-A epoxy resin, ethyl acetate, polyvinyl alcohol, bentonite, sodium dodecyl benzene sulfonate, nanometer titania, methylisothiazolinone, sodium citrate, tributyl citrate, antibacterial agent, deforming agent, dispersing agent, coalescing agent, thickening agent, isopropyl alcohol and deionized water. In the coating, the organosilicon-modified epoxy resin is matched with the bisphenol-A epoxy resin, so that the coating has high glossiness, high anti-static electricity capacity, high mechanical property, high aging resistance and high chemical corrosion resistance; the methylisothiazolinone and the antibacterial agent are added, so that the antibacterial capability of the coating can be improved effectively; moreover, the environment-friendly waterproof antibacterial coating has the advantages of low cost, environmental friendliness, high adhesive force, high extensibility, high temperature resistance and long service life; a roller coating way is adopted instead of spraying during coating, so that the production environment is improved effectively, and the physical health of workers is facilitated.

Description

technical field

[0001] The invention relates to an environment-friendly waterproof and antibacterial paint and a preparation method thereof. Background technique

[0002] Paint, traditionally called paint in China. The so-called coating is coated on the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the object to be coated. Corresponding additives, viscous liquid prepared with organic solvent or water. The authoritative book "Coating Technology" in China's coating industry defines it as follows: "Coating is a material that can be coated on the surface of objects by different construction techniques to form a firm adhesion, a certain strength, and a continuous Solid film. The film formed in this way is generally called a coating film, also known as a paint film or coating.”

[0003] People often come into contact with some toxic compounds in the process of daily use of coatings, and these compounds will cause c...
