Abstract

The invention discloses a superhydrophobic anticorrosive coating for marine concrete, the superhydrophobic anticorrosive coating is prepared from the following raw materials by weight: 60-80 parts ofmodified silicon-acrylic emulsion, 1-2 parts of orthosilicate, 4-6 parts of methyltriethoxysilane, 30-40 parts of ethanol, 0.5-1 part of 2-amino-2-methyl-1-propanol and 5-10 parts of ammonia water. The invention also discloses a preparation method of the superhydrophobic anticorrosive paint for the marine concrete. The superhydrophobic anticorrosive paint for the marine concrete has the excellentperformances of long-lasting weather resistance and long-lasting corrosion resistance, and has broad market development prospects. The methyltriethoxysilane and the ethyl orthosilicate are hydrolyzedand polycondensed in the modified silicone-acrylic emulsion to form an inorganic network, and the organic-inorganic hybrid superhydrophobic anticorrosive coating can be obtained.

Description

technical field

[0001] The invention belongs to the technical field of coatings, and in particular relates to a superhydrophobic anticorrosion coating for marine concrete and a preparation method thereof. Background technique

[0002] A superhydrophobic surface refers to a surface with a contact angle with water droplets greater than 150° and a roll angle less than 10°. Since the discovery of the "lotus leaf effect", superhydrophobic surfaces have been widely used in fields such as self-cleaning, anti-corrosion and anti-mildew, anti-icing and anti-frost, and oil-water separation. The ocean covers 4 / 5 of the earth, and my country has more than 3 million square kilometers of sea area. The development of marine resources can effectively alleviate the current shortage of resources. Seawater is the largest and highly corrosive natural electrolyte in nature. Seawater contains almost all chemical elements on the earth, and its composition is very complex. In addition, seawater a...
