Problems solved by technology

In the storage process of water-based paint, the performance of the product is often damaged due to the reproduction of bacteria, and the quality is reduced, resulting in discoloration of the paint surface, a decrease in viscosity, a change in pH value, odor and even mildew on the surface.
Ultimately, the paint will be discarded, causing losses to users and producers

Abstract

The invention relates to a novel latex paint green anti-corrosion system and application of the novel latex paint green anti-corrosion system in interior wall latex paint. The latex paint green anti-corrosion system is prepared from a quick bactericide (DBNPA type& CMIT type), a long-acting long-lasting bactericide (MIT type & BIT type), and a dry film mildewproof agent (IPBC type & OTI& ZPT type). No reaction occurs among the preservatives, so that the phenomenon that the antiseptic and mildew-proof effects are reduced due to the reaction among different preservatives is avoided; and by adjusting the dosage of each preservative in the preservative combination, a new preservative combination which not only meets the standard GB / T 35602-2017 but also has no adverse effect on the original performance of the product is obtained. The latex paint green anti-corrosion system combination has the advantages of being green and environmentally friendly to human bodies and the environment and the like while having excellent in-tank antibacterial and dry film mildew-proof performance.

Description

technical field [0001] The invention belongs to the field of coating anticorrosion, and in particular relates to a novel latex paint green anticorrosion system and its application in interior wall latex paint. Background technique [0002] During the coating preparation process, in order to improve the construction performance and film performance of the coating, the additives added often contain the nutrients necessary for microorganisms, which provides a good growth environment for microorganisms such as bacteria, molds and yeasts. During the storage of water-based coatings, the performance of the product is often damaged due to the reproduction of bacteria, and the quality is reduced, resulting in discoloration of the coating surface, a decrease in viscosity, a change in pH value, odor and even mildew on the surface. Eventually, the paint will be discarded, causing losses to users and producers. Therefore, when producing and storing coatings, certain antibacterial and an...
