Embodiment 1

[0022] Example 1: Under stirring and dispersing conditions, add 1g coalescent NX-795 (trade name), 0.1g emulsifier Tween-20, 0.1g multifunctional in 25ml styrene / acrylate copolymer coating emulsion Auxiliary octylphenol polyoxyethylene ether, and then take an appropriate amount of water to wet 0.1g of nano-titanium dioxide, add 0.05g of dispersant sodium tripolyphosphate, and add 0.1g of antifungal agent (trichlorophenylmaleimide). Add 75ml of water and mix to obtain an antibacterial, anti-mildew and deodorizing coating. After being coated on the surface of the article and air-dried to form a film, it can play the role of anti-bacterial, anti-mildew and deodorizing. Apply the bacterial liquid on the surface of the antibacterial and mildew-proof film, after 0, 2, 4, 8, 12, and 24 hours, place the bacterial liquid in physiological saline, shake it, take 0.3ml into a petri dish, pour it into the culture medium, and put it in Cultivate in the incubator for 48 hours, take out and c...

Abstract

The invention relates to a method for preparing an antibacterial and antifungal agent on the surface of buildings, adding film-forming aids, nano-TiO2, dispersants, emulsifiers, multifunctional auxiliary agents and antifungal agents to coating emulsions for architectural coatings. The weight percentage of each component is controlled as follows: 20%-90% of coating emulsion, 0.1%-5% of nano-TiO2, 0.1%-10% of film-forming aid, and 0.05%-0.5% of dispersant , 0.1% to 1% emulsifier, 0.1% to 1% multifunctional additive, 0.1% to 10% anti-mold additive, and 5% to 70% water. The antibacterial and antifungal agent prepared by the present invention can be sprayed on the surface of buildings at any time to renew the catalytic antibacterial and antifungal coating. The catalysis and antifungal agent have synergistic bactericidal and antifungal effects, can remove volatile gases such as formaldehyde VOC, and have a simple preparation method, few additives, 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...
