Antibacterial coating material additive and preparation method thereof

Abstract

The present invention discloses an antibacterial coating material additive and a preparation method thereof. The coating material additive comprises the following raw materials by weight: 33-45 parts of maifanite, 20-28 parts of tourmaline, 5-10 parts of silver ion, 1-5 parts of polyurethane, 5-10 parts of sodium sulfonate diethyl succinate, 1-5 parts of diphenyl dihydroxy silane, 1-3 parts of epoxy sodium carboxymethylcellulose, 10-17 parts of titanium dioxide, and 40-50 parts of water. The preparation method comprises: mixing the raw materials excluding silver ions, carrying out ball milling, adding water to the powder obtained after the ball milling, heating to a temperature of 45 DEG C, carrying out sealed stirring, adding the silver ions, continuously carrying out sealed stirring, and cooling to a room temperature to obtain the product. According to the present invention, after the antibacterial coating material additive is added to an aqueous coating material, the obtained aqueous coating material has advantages of good water resistance, high hiding power and scrub resistance, and has effects of oxygen ion releasing and sterilizing; and the antibacterial coating material additive further can be used in the ceramic tile field, and further has effects of oxygen ion releasing, sterilizing and environmental pollution reducing, wherein the performance of the ceramic tile can be improved, the concave-convex texture of the ceramic tile is clear, the three-dimensional effect of the ceramic tile is strong, the ceramic tile body is effectively protected, and the gloss is enhanced.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a sterilizing coating additive and a preparation method thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” Among them, wa...

Problems solved by technology

However, the production cost of existing water-based paints is relatively high, and the residual time of organic volatiles is long. Among them, free formaldehyde and TDI are highly toxic to the body, especially unfavorable for the healthy development of adolescents and children, and will cause environmental pollution.
