Abstract

The invention discloses a self-cleaning hydrophobic titanium dioxide coating and a preparation method thereof, and relates to the technical filed of coatings. The coating comprises the following raw materials in parts by weight: 10-20 parts of nano-titanium dioxide photocatalyst powder, 5-10 parts of polystyrene, 5-10 parts of dimethylformamide, 10-20 parts of composite abrasive material particles, 1-3 parts of a dispersant, 1-3 parts of a curing agent, 5-10 parts of an organic amine adhesion modifier, 1-3 parts of a defoaming agent, 10-20 parts of an oil stain-resistant resin base material, 0.5-1.6 parts of a thickener and the balance of deionized water. According to the self-cleaning hydrophobic titanium dioxide coating and the preparation method thereof, the purpose of improving the abrasion resistance, adhesion, antibacterial property and oil resistance of a coating by modifying components of the coating can be realized, the purpose of improving the abrasion resistance, adhesion, antibacterial properties and oil resistance of the coating based on retaining the good self cleaning and hydrophobicity is well achieved, the adhesion and abrasion resistance of the coating are greatlyimproved, the service life is better prolonged, and the coating has the effects of having antibacterial properties, preventing the growth of microorganisms and preventing oil.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-cleaning hydrophobic titanium dioxide coating and a preparation method thereof. Background technique [0002] 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, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Auxiliary, a viscous liquid prepared with organic solvents or water. Coating is a material that can be coated on the surface of objects by different construction techniques to form a continuous solid film with strong adhesion and certain strength. , The film formed in this way is commonly called a coating film, also known as a paint film or a coating. In the early days, most of the coatings used vegetable oil as the main raw material, so they were called "paints". The coating products that use synthetic ch...
