Problems solved by technology

[0002] Paint is sprayed or brushed on the surface of the building or decoration to be coated, and can form a continuous film with the surface of the object to be coated. There are many types of paint, including water-based paint, latex paint, etc. After the film is formed, there are various formula ratios for antibacterial properties, scrub resistance, water resistance and artificial aging resistance. At present, most of the preparation methods of antibacterial coatings use relatively complex ingredients, and the preparation methods are complicated. And in Antibacterial, scrub resistance, alkali resistance, water resistance and artificial aging resistance can not be better

Abstract

The invention provides a preparation method of an antibacterial coating. The preparation method comprises the following steps: (1) sequentially and respectively adding a silane coupling agent, an adhesive, an antibacterial agent and an organic solvent into a reaction kettle to obtain a polymer, wherein the weight part ratio of the silane coupling agent to the adhesive to the antibacterial agent to the organic solvent is (1-348): (2-250): (3-120): (16-340); (2) dropwise adding 200-980 parts by weight of deionized water or distilled water into the polymer in the step (1), and stirring at the rotating speed of 100-300rpm while dropwise adding to obtain the antibacterial coating; (3) stirring the antibacterial coating obtained in the step (2) at the rotating speed of 20-50rpm for 2 hours, transferring into a sealed container, and standing for more than 12 hours; the preparation method has the beneficial effects that the sprayed coating has a long-acting antibacterial effect and has relatively high alkali resistance, water resistance and artificial aging resistance.
