Two-component water-based polyurethane antibacterial and antifungal coating for cigarette factory and preparation method thereof

Abstract

The present invention provides a two-component water-based polyurethane antibacterial and antifungal paint for cigarette factories, comprising a mixed component A and a component B, wherein the component A includes the following components: deionized water, water-based modified acrylic resin, primary wetting agent, defoamer, water-based zinc pyrithione, water-based 2-n-octyl-4-isothiazoline-3-one, butylcarbamic acid-3-iodine-2- Propynyl ester, second wetting agent, water-based white paste, matting powder, kaolin, leveling agent and thickening agent; the component B is a curing agent, when in use, after mixing component A and component B Apply evenly to the wall. The beneficial effects of the present invention are as follows: the present invention can effectively inhibit the growth of mold in tobacco factories on the wall surface, and the formed coating has excellent anti-aging performance, ensuring long-term use without discoloration and affecting the appearance, and at the same time, the cost of the coating is relatively high. Low cost and simple construction, which can create convenient conditions for mass promotion.

Description

technical field [0001] The invention relates to the field of anti-mildew on the walls of cigarette factories, in particular to a two-component water-based polyurethane antibacterial and anti-mildew paint for anti-mildew in cigarette factories and a preparation method. Background technique [0002] The mold species that cause mold on the wall are different in different environments, so it is particularly important to study the special anti-mold wall coating in special environments. [0003] my country's cigarette production plants, especially the walls and tops of the silk-making workshops, silk-storage rooms and other rooms have been in a high temperature and high humidity environment for a long time, which provides good conditions for the growth of various molds. The tobacco leaf powder on the walls and top surfaces provides rich nutrients for the growth of special molds. Therefore, a large number of molds appear on the walls and top surfaces of many tobacco factories in my ...

Problems solved by technology

[0003] my country's cigarette production plants, especially the walls and ceilings of silk workshops and silk storage rooms, have been in a high-temperature and high-humidity environment for a long time, which provides good conditions for the growth of various molds. Not only that, the deposition The tobacco leaf powder on the wall and top surface provides rich nutrients for the growth of special molds. Therefore, a large number of moldy phenomena appear on the walls and top surfaces of many tobacco factory buildings in my country, which not only affects the appearance of the production workshop, More importantly, the production of mold has also seriously affected the hygienic quality of cigarettes, and it will also have serious adverse effects on the physical and mental health of workers who have been working in a mold environment for a long time

[0004] The existing cigarette factories use anti-mildew coatings for basements or food factories. This kind of coating mainly uses acrylic acid as the main film-forming substance. The tobacco factories use this kind of coating for coating treatment. Practice has proved that the anti-mildew effect is not good.

[0005] There are also some cigarette factories trying to use tiles to decorate the wall to prevent mildew, but because the tiles are pasted too high, there is a safety problem of falling, and they cannot completely cover the wall and the top of the wall, and mold will still be generated in the tile splicing gap, which is still not achieved Expected anti-mildew effect

[0006] In addition, some tobacco factories use aluminum gussets for wall decoration, and the installation of aluminum gussets requires the erection of keels. Although the aluminum gussets themselves do not grow mold, the wall on the side of the keel on the back of the aluminum gussets still grows mold, which will still affect The quality of cigarettes and the health of personnel, and the high cost of aluminum gussets and inconvenient maintenance after operation

[0007] Therefore, at present, the mildew-proof coatings and methods for the walls of cigarette factories cannot solve the problem of mildew in cigarette factories, and there is an urgent need for a mildew-proof method suitable for cigarette factory walls.
