Problems solved by technology

[0004] However, the water-based thin steel structure fireproof coatings currently produced in China generally have shortcomings and problems such as poor fireproof performance, low expansion ratio of the expansion layer, low structural strength, and poor water resistance of the coating film. At the same time, the existing water-based thin steel structure fireproof Coatings also do not have very good anti-corrosion, anti-mildew and anti-rust functions, and it is difficult to meet the requirements of different buildings. This has also become a problem that technical workers in the field need to solve urgently.

[0029] E1: polymer modified graphene oxide, prepared by the following method:

[0030] (1) Synthesis of NTDA-terminated polypyrrolene prepolymer

[0031] In a 100 mL dry three-necked flask, add 10 mmol of 3,3'-diaminobenzidine DAB, 11 mmol of 1,4,5,8-naphthalene tetracarboxylic anhydride NTDA, 22 mmol of benzoic acid, 3 mL of isoquinoline and 40 mL of m -cresol, under nitrogen protection and magnetic stirring; after 2 hours, heat up to 85°C for 6h, 190°C for 21h, after the reaction, cool down to 70°C and quickly pour it into 150mL methanol to obtain a large amount of solid precipitation; wash the product repeatedly with methanol Finally, filter and collect the polymer, and dry it in a vacuum oven at 160°C for 20 hours for use;

[0032] (2) Synthesis of amino-terminated sulfonated polyimide prepolymer

[0033] In a 100mL dry three-neck flask, add 1.6mmol 2,2'-bis(4-sulfophenoxy)biphenyldiamine, 12.5mL m-creso1 and 0.8mL triethylamine successively, and protect with nitrogen ga...

Embodiment 1

[0054] In parts by weight, add 10 parts of A1, 20 parts of B1, 8 parts of C1, 6 parts of D1, 20 parts of E1 and 15 parts of F1 into the mixer and mix thoroughly for 10 minutes to obtain a water-based anti-corrosion, anti-mildew and anti-rust coating. The water-based anti-corrosion, anti-mildew and anti-rust paint is coated on the steel structure to complete the construction.

Abstract

The invention discloses water-based anticorrosive mildewproof antirust paint. The water-based anticorrosive mildewproof antirust paint is prepared from diatomite, deionized water, polyoxyethylene polyoxypropylene ether, KH-560, polymer-modified graphene oxide and sulfonated polybenzimidazole-modified octaphenyl polyhedral oligomeric silsesquioxane-wrapped nano-silver. The water-based anticorrosive mildewproof antirust paint has the advantages of being high in adhesive force and hardness, good in fireproof property and scratch resistance, excellent in weather resistance and water resistance, good in corrosion resistance, mildew resistance and rust resistance, little in harm to a human body and pollution to the environment during preparation and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a water-based anti-corrosion, mildew-proof and anti-rust coating. Background technique [0002] With the development of industrialization, especially in the construction of large and medium-sized cities, steel structures have become a very important construction application material due to their fast and convenient construction advantages. As metal steel structures, they are mostly used in standard In factories, large stadiums, airports, bridges, three-dimensional garages and nuclear buildings. However, the fire resistance of steel structures is far inferior to that of brick-concrete structures. The critical temperature of steel is 540°C. When this temperature is reached, its bearing capacity will be reduced by about half. In a general fire, this temperature can be reached in about 15 minutes, leading to the collapse of the building. This charact...
