Problems solved by technology

Because if some preservatives that do not require special stability are combined with dry film antifungal agents (such as: combining MIT with dry film antifungal agents, or combining BIT with dry film antifungal agents), the anticorrosion and mildew resistance of the product will be improved. The effect will be very poor and economically difficult to achieve. At the same time, the antibacterial spectrum complementarity and compatibility of the composition also require a large number of microbial experimental screening.
Due to the above reasons, so far, there is no in-can preservative and dry film antifungal composition on the market

Abstract

The invention relates to an in-tank antiseptic antimildew agent composition integrated with a dry film for paint. The composition is prepared from a water-based paint in-tank antiseptic bactericide, a dry film antimildew agent, a solvent, an aid, a stabilizing agent and water. The in-tank antiseptic antimildew agent composition integrated with a dry film for paint has the advantages of reasonable formula, advanced process, good corrosion and mildew prevention effects, good stability, and the like. When the in-tank antiseptic antimildew agent composition integrated with a dry film for paint is used for paint, salt cluster phenomena can be avoided, an in-tank antiseptic effect can pass a microorganism challenge test, and the dry film mildew-growing grade is a zero grade.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical anti-corrosion and anti-mold agents, and relates to an anti-corrosion and anti-mold agent composition for water-based coatings in tanks and dry films and a preparation method thereof. Background technique [0002] Water-based paints will be polluted and destroyed by harmful microorganisms in the process of production and storage, which will cause the paint to change color, flatulence, smell, demulsify, precipitate, and even lose its practical value. For many functional coatings or coatings used for special occasions, not only are the coatings required to be free from microbial contamination during production and storage, but they should also last as long as possible after the coating is painted to prevent bacteria, Mold and algae attack. For example, for hospitals, food processing places, bathing places, villa areas, house exterior walls (in most parts of southern my country), und...
