Preparation method of hydrophobic antifouling ground coat slurry

Abstract

The invention discloses a preparation method of hydrophobic antifouling ground coat slurry, which comprises the steps of adding absolute ethyl alcohol into modified epoxy resin, ultrasonically dispersing and dissolving, magnetically stirring, adding ammonia water, reacting at constant temperature, adding hydrogen-containing silicone oil and dibutyltin dilaurate, and stirring for hydrophobic modification to obtain a hydrophobic sol material; dispersing the dopamine-modified nano aluminum oxide in deionized water, adding 4-dimethylaminobutylamine and propane sultone to react, centrifuging, and washing with deionized water and ethanol respectively to obtain zwitterionic modified nano aluminum oxide; and uniformly mixing stearic acid modified kaolin, modified nano silicon dioxide, the hydrophobic sol material and zwitterionic modified nano aluminum oxide, adding sodium tripolyphosphate and methyl cellulose, and performing ball milling to obtain the hydrophobic antifouling ground coat slurry.

Description

technical field [0001] The invention belongs to the field of glazes, and in particular relates to a method for preparing a hydrophobic and antifouling bottom glaze slurry. Background technique [0002] The unique properties of superhydrophobic surfaces make them have broad application prospects in the fields of self-cleaning, anti-corrosion, drag reduction, etc., and have always been an important topic of research for researchers. In the research of superhydrophobic performance, it is found that there are two main factors affecting the hydrophobic performance of the surface: one is the chemical properties of the surface material, and the other is the microstructure of the surface. Based on this, researchers have prepared various biomimetic superhydrophobic coatings, but most superhydrophobic coatings are difficult to be applied in practice. There are two main reasons for this: first, the preparation cost of superhydrophobic coatings is high 1. The process is complicated; th...

Based on this, researchers have prepared various biomimetic superhydrophobic coatings, but most superhydrophobic coatings are difficult to be applied in practice. There are two main reasons for this: first, the preparation cost of superhydrophobic coatings is high 1. The process is complicated; the second is that most superhydrophobic coatings only pay attention to their superhydrophobicity, while ignoring other properties necessary for engineering applications
