Abstract

The invention discloses a paint for bathroom products, and a preparation method and application thereof. The paint for bathroom products is composed of a primer and a finish paint. The primer is prepared from a polyacrylate emulsion, polyoxyethylene ether, calcium carbonate and food-grade barium sulfate. The finish paint is prepared from fluorine silicon carbon compounds, polysiloxane, polyfluorocarbene, a silane coupling agent, calcium carbonate, food-grade barium sulfate, silicon dioxide, kaolin, titanium dioxide and a defoaming agent. The preparation method comprises the following steps: mixing and stirring the primer raw materials to obtain a transparent uniform mixed solution which is the primer; and uniformly mixing and stirring the fluorine silicon carbon compounds, polysiloxane and polyfluorocarbene, sequentially adding the silane coupling agent, calcium carbonate, food-grade barium sulfate, silicon dioxide, kaolin, titanium dioxide and defoaming agent, and stirring to obtain a uniform viscous white oily liquid which is the finish paint. The paint for bathroom products has the advantages of favorable water resistance, stable antibacterial effect, high firmness and durability and stable service life.

Description

technical field [0001] The invention relates to the field of coating compositions, in particular to a coating for sanitary products and a preparation method and application thereof. Background technique [0002] Paint is a layered thin film material coated on the surface of an object to play the role of protection, decoration and identification. Sanitary products are utensils used in places such as toilets and bathrooms, mostly ceramics and antirust metals. The use environment of sanitary products has high humidity, heavy water vapor and high temperature, which is easy to breed bacteria. Therefore, the surface of sanitary products can be coated with coatings. The coatings used must have the characteristics of hydrophobicity and rust resistance, antibacterial and antifouling, solid and durable, and must also have good skin contact compatibility. [0003] Currently commercially available toilet waterproof coatings can be summarized into the following categories: non-tar-type...
