Abstract

The invention relates to the technical field of coating materials and in particular relates to a waterproof antifouling antimicrobial and antibacterial coating material. The coating material comprisesthe following components in parts by weight: 60-65 parts of normal propyl alcohol, 20-25 parts of isopropanol, 10-15 parts of water, 0.003-0.007 part of nano-silver and 70-80 parts of resins. The invention further discloses a preparation method of the coating material. The preparation method comprises the following steps: S1, weighing various components in parts by weight of the various components; S2, adding the resins, nano-silver and water in parts by weight into a ball-milling kettle, stirring, further stirring, and fully grinding the obtained mixed solution so as to obtain a ground mixedsolution; S3, adding normal propyl alcohol and isopropanol in proportional quantity into the ground mixed solution, heating in a reactor, stirring and reacting, and performing ultrasonic treatment toobtain slurry; and S4, dispersing, thereby obtaining the coating material. The waterproof antifouling antimicrobial and antibacterial coating material disclosed by the invention has the characteristics of being easy to clean and capable of avoiding water penetration and oil penetration, further has antimicrobial and antibacterial effects and the like, can be applicable to coating of large curtainwall and glass surfaces, and can also be used for coating of kitchen ware surfaces.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a waterproof, antifouling, antibacterial and bactericidal coating material and a preparation method thereof. Background technique [0002] Coating materials are solid continuous film materials that are coated on the surface of objects for the purpose of protection, insulation, decoration, etc. Great variety. Coating materials can not only prolong the service life of objects, but also use the unique functions of coatings to improve the office and living environment. [0003] With the rapid development of modern economy and society, people put forward higher and higher requirements for antibacterial products. At the same time, when coating materials are used in some large-scale curtain walls, waterproof and antifouling properties are also one of the indicators for evaluating the coating materials used. [0004] Chinese patent CN101701120 discloses a nano-zinc oxide ant...
