Adding ethanol, dimethyl octadecyl [3- (trimethoxysilyl) propyl ] ammonium chloride, 1- (6-chloro-3-pyridazinyl) piperidine-4-methyl formate, samarium tris (acetylacetonate), neodymium 2-ethylhexanoate, polyoxyethylene polyoxypropylene ether and ethylene glycol monomethyl ether into a reaction kettle in parts by weight, heating, and uniformly stirring to obtain the antibacterial material product for the resin coating.
Description
Technical Field
The invention relates to a preparation method of an antibacterial material, in particular to a preparation method of an antibacterial material for resin coatings.
Background
The coating is traditionally named as paint in China. The coating is a continuous film which is coated on the surface of an object to be protected or decorated and can form firm adhesion with the object to be coated, and is a viscous liquid which is prepared by taking resin, oil or emulsion as a main material, adding or not adding pigments and fillers, adding corresponding auxiliaries and using an organic solvent or water.
In a humid environment, the paint for buildings often grows fungi and other bacteria, which not only affects the appearance of the buildings, but also seriously affects the sanitary environment inside and outside the buildings.
CN104845425A discloses a method for preparing a mildew-proof antibacterial coating, which comprises the following steps: adding the mildew-proof antibacterial agent, the pigment and filler, the wetting dispersant and the defoaming agent into a stirring tank; then mixing the acrylic emulsion, the film forming additive and the thickening agent, and uniformly stirring; the mildew-proof antibacterial agent comprises chitosan quaternary ammonium salt, montmorillonite, a composite material of the chitosan quaternary ammonium salt and the montmorillonite nanometer, and a composite material of the silver-loaded chitosan quaternary ammonium salt and the montmorillonite nanometer.
CN107027807A discloses an inorganic antibacterial agent and application thereof in building coatings, wherein the inorganic antibacterial agent is prepared by grinding nano silver chloride, nano alumina and nano calcium oxide, and the weight ratio of the nano silver chloride to the nano alumina to the nano calcium oxide is 100: (30-40): (14-18).
Most of the existing preparation methods of the antibacterial material for the resin coating use inorganic matters or load containing silver elements as the antibacterial agent, but the silver elements belong to heavy metal elements and have certain cytotoxicity, so the antibacterial material has certain harmfulness to human bodies and the environment.
Disclosure of Invention
