Preparation method of antibiotic anti-fungus agent for building surface

Abstract

The invention relates to a preparation method of an antiseptic and mold-proof agent that is used on building surfaces. The preparation method comprises the following steps: the film forming aid, the nanometer TiO2, the dispersing agent, the emulsifier, the multifunctional promoter and the mold-proof promoter are added into the coating solution which is used as a building covering material, dispersed and mixes;, the weight percentage of every components are controlled as: coating solution 20% to 90%, nanometer TiO2 0.1% to 5%, film forming promoter 0.1% to 10%, dispersing agent 0.05% to 0.5%, emulsifier 0.1% to 1%, multifunctional promoter 0.1% to 1%, mold-proof promoter 0.1% to 10% and water 5% to 70%. The mold-proof agent prepared by the invention can be sprayed on the building surfaces at any time to renew catalytic the mold-proof coatings; the application method is simple and flexible, and the mold-proof agent has very good combining power and consistency with the covering materialsof the inner and exterior walls; the mold-proof agent simultaneously makes full use of the synergism of sterilization and mold-proof by the nanometer titanium dioxide catalytic and mold-proof agent;the mold-proof agent can remove the formaldehyde VOC and other volatile gases; the invention has the advantages of simplicity, few addition agents and low production cost .

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and antifungal agent, in particular to the preparation of an antibacterial and antifungal agent containing nano-titanium dioxide. The obtained antimicrobial and antifungal agent can be used for antibacterial and antifungal of building interior and exterior walls and deodorization. Background technique [0002] Nano-TiO2 is a non-eluting antibacterial agent based on photocatalytic reaction to decompose organic matter and has antibacterial effect. It has good chemical stability, non-toxicity, low heavy metal content, broad-spectrum and long-term antibacterial properties. The more widely used in people's daily life. Among them, in the aspect of building interior and exterior wall coatings, there are many antibacterial coatings prepared by using nano-titanium dioxide. The components include: film-forming agent silicon-acrylic emulsion 20% to 25%, nitrogen-doped nano-TiO 2 20%~10%, ordinar...
