AI Technical Summary

Problems solved by technology

Diuron is acute toxicity: LD (minimum lethal dose) is about 500mg / kg, specific disadvantages are: harmful to the ecological environment; no high-efficiency broad-spectrum activity to prevent the growth of mold and algae; high water solubility (precipitation rate); tank Poor pH stability of internal and paint film; high VOC; poor compatibility with many formulations; affects the performance of dry film; causes color change, etc.
[0005] Therefore, the traditional single organic antifungal agent has poor broad and long-term effects, strong toxicity, and is easy to be hydrolyzed. When a large amount of organic antifungal agent is added, it is easy to cause safety accidents, which affects the antifungal property during use.

TM 2468, 8 parts; dispersant Dispersant 5027, 0.8 parts; wetting agent XP-40, 0.25 parts; defoamer Dispelair CF 38, 0.5 parts; propylene glycol 1.0 parts; AMP-95, 0.05 parts; disperse for 5 minutes;

[0049] 2) Under the rotating speed of 800 rpm, continue to drop in heavy calcium carbonate CC-800, 60 parts; Zinc oxide, 10 parts;

[0050] 3) Disperse for 10 minutes at 1200 rpm;

[0051] 4) At a speed of 450 rpm, add 0.6 parts of film-forming aid TEAXNAL; 0.6 parts of antifungal agent ZPT (zinc pyrithione); 1 part of thickener ACRYSOL TT-935; after dispersing for 5 minutes ;

[0052] 5) Prepare mildew-resistant putty and take samples for inspection.

Embodiment 3

[0054] A preparation method of the anti-mildew putty specifically comprises the following steps:

[0055] 1) According to 100 parts by weight, weigh 17 parts of water, and put them into synthetic resin emulsion Elastene at a speed of 600 rpm. TM 2468, 8 parts; dispersant Dispersant 5027, 0.8 parts; wetting agent XP-40, 0.25 parts; defoamer Dispelair CF 38, 0.5 parts; propylene glycol 1.0 parts; AMP-95, 0.05 parts; disperse for 5 minutes;

[0056] 2) Under the rotating speed of 1000 rev / mins, continue to drop into heavy calcium carbonate CC-800, 55 parts; Zinc oxide, 15 parts;

[0057] 3) Disperse for 5 minutes at 1500 rpm;

Abstract

The invention discloses anti-mold putty with high-content zinc oxide compounded with organic zinc and a preparation method of the anti-mold putty. The anti-mold putty is prepared from the following specific components in percentage by weight: 10.0-20.0% of water, 0.3-1.0% of a dispersing agent, 0.2-0.5% of a moistening agent, 0.05-0.2% of a pH value adjusting agent, 0.1-0.8% of a defoaming agent, 0.5-1% of propylene glycol, 2.0-15% of zinc oxide, 0.2-1.5% of zinc pyrithione, 50-70% of coarse whiting, 0.2-1.0% of a filming agent, 5.0-10.0% of a synthesis resin emulsion and 0.5-2.0% of a thickening agent. As a proper amount of the zinc oxide is compounded with a small amount of organic zinc ZPT (Zinc Pyrithione), a synergistic effect can be achieved when the two substances are compounded, and thus the anti-mold functions of the two components can be greatly improved.

Description

technical field [0001] The invention relates to an anti-mold putty, in particular to an anti-mold putty with a high content of zinc oxide compounded with organic zinc and a preparation method thereof, belonging to the field of functional decorative coatings. Background technique [0002] Microorganisms widely exist in nature. Usually, the natural conditions suitable for mold to reproduce and grow are temperature 23°C-38°C and relative humidity 85%-100%. The walls, ceilings, floors, underground projects, etc., are suitable for the growth of molds. They multiply rapidly and produce various metabolites of enzymes, acids and toxins, which affect the appearance and quality of items, and pollute the environment and endanger animals. Plant growth and human health. If ordinary decorative paint is used, it will be corroded by mold to varying degrees, and mold is more serious for organic paint coatings, and the coating corroded by mold will fade, stain, and even fall off. This is be...
