Problems solved by technology

[0007] In addition, zinc compounds have also been known as antibacterial agents since ancient times, but they are also highly water-soluble, and there is a disadvantage that they are easily lost when they come into contact with water even if they are enclosed in a resin.

[0083] (acrylic emulsion)

[0084] In a reaction vessel equipped with a stirrer, a reflux condenser, and a dropping funnel, 550 g of deionized water was put in as an initial feed, nitrogen was sealed after deoxidation, and the temperature was raised to 76°C. After uniformly mixing 484 g of butyl acrylate, 516 g of methyl methacrylate, 11 g of N-methylol acrylamide, 26 g of acrylic acid, and 26 g of 80% methacrylic acid, in this beaker, mix 285 g of deionized water to dilute High Tenol NF -17 (trade name manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd., polyoxyethylene styrenated phenyl ether ammonium sulfate system) 23 g. After standing for a while, it was uniformly emulsified with a homomixer to obtain a monomer emulsion. 4% of this emulsion was charged into a reaction vessel, and a solution obtained by dissolving 0.004 g of iron sulfate heptahydrate in 10 g of deionized water, 2.4 g of ammonium persulfate, and a solution obtained by dissolving 20 g of deionized water ...

Abstract

The invention provides an aqueous coating agent, and is characterized in that the aqueous coating agent contains (A) resin emulsion having a film forming capability by using a surfactant and emulsion polymerization, (B) a boron compound, and (C) a zinc compound, and the using ratio of the (B) boron compound and the (C) zinc compound is 10:1-0.1:1 measured with the mass ratio. The invention provides the aqueous coating agent which not only has excellent mildewproof and antibacterial performance, but also has excellent safety and weather resistance performance, effects can be sustained for a long time even if under conditions of high humidity or exposed to wind and rain, and the aqueous coating agent can be used for indoor and outdoor plastic material, paper material, wood, fiber material, metal material, concrete material and other inorganic material.

Description

technical field [0001] The present invention relates to a water-based coating agent having antifungal and antibacterial properties capable of exerting an effect for a long period of time even under conditions of high humidity in which mold is likely to form or exposed to wind and rain. [0002] In addition, the present invention relates to an antifungal agent and an antibacterial agent comprising or consisting of the water-based coating agent, and to a paper-based fiber material treated with the water-based coating agent. Background technique [0003] Originally, in our country with high temperature and high humidity, there are many harms of mold, and the health hazard of mold has become a social problem. In addition, it is difficult to suppress the occurrence of mold damage for a long period of time under conditions of high temperature and high humidity. Therefore, various antifungal agents have been blended into coating agents for a long time. It is known to use organic ...
