Embodiment 1

[0024] Put 10g of superfine pulverized coal furnace fly ash with an average particle size of 2.8μm, 10g of calcium hydroxide, and 150g of water into a three-neck flask with a temperature of 60 degrees in a water bath, with a stirring speed of 1000r / min, and adjust the gas flow to Inject CO at 1.2L / min 2 The gas undergoes carbonization reaction, and the change of pH during the reaction process is recorded online. After 8 minutes, the aeration is stopped to end the reaction, and the modified ultrafine solid waste particles are obtained by filtering and drying.

[0025] In 50ml of heptadecafluorodecyltriethoxysilane ethanol solution with a concentration of 0.1%, add 1g of carbonized modified ultrafine pulverized coal furnace fly ash, and ultrasonicate for 20min to obtain a superhydrophobic coating.

Embodiment 2

[0027] Put 10g of superfine pulverized coal furnace fly ash with an average particle size of 2.8μm, 10g of calcium hydroxide, and 150g of water into a three-neck flask with a temperature of 60 degrees in a water bath, with a stirring speed of 1000r / min, and adjust the gas flow to Inject CO at 1.2L / min 2 The gas was carbonized, and the pH change during the reaction was recorded online. After 16 minutes, the aeration was stopped to end the reaction, and the carbonic acid modified particles were obtained by filtration and drying.

[0028] In 50ml of heptadecafluorodecyltriethoxysilane ethanol solution with a concentration of 0.1%, add 1g of carbonized modified ultrafine pulverized coal furnace fly ash, and ultrasonicate for 20min to obtain a superhydrophobic coating.

Embodiment 3

[0030] Put 10g of superfine pulverized coal furnace fly ash with an average particle size of 2.8μm, 10g of calcium hydroxide, and 150g of water into a three-neck flask with a temperature of 60 degrees in a water bath, with a stirring speed of 1000r / min, and adjust the gas flow to Inject CO at 1.2L / min 2 The gas was carbonized, and the pH change during the reaction was recorded online. After 24 minutes, the aeration was stopped to end the reaction, and the carbonic acid modified particles were obtained by filtering and drying.

[0031] In 50ml of heptadecafluorodecyltriethoxysilane ethanol solution with a concentration of 0.1%, add 1g of carbonized modified ultrafine pulverized coal furnace fly ash, and ultrasonicate for 20min to obtain a superhydrophobic coating.

Abstract

The invention relates to the technical field of coating, and in particular to a solid waste based super-hydrophobic coating and a coating method thereof. The solid waste based super-hydrophobic coating has the advantages that ethyl alcohol is adopted as a diluting dispersant, utilization of volatile organic solvents is avoided, and the waterproof coating is enabled to be environment-friendly; by utilizing solid waste granules, cost can be reduced, and waste can be turned into wealth; manufacturing steps are simple and easy to control, large-scale industrial production is benefited, and the coating method is simple and easy to generalize.

Description

technical field [0001] The invention relates to the field of coatings, more specifically, to a solid waste-based superhydrophobic coating and a coating method thereof. Background technique [0002] In general, a solid surface with a water contact angle of less than 90° is called a hydrophilic surface, and a surface with a contact angle greater than or equal to 90° is called a hydrophobic surface. Among them, the surface whose contact angle with water is less than 10° is a superhydrophilic surface, and the surface whose contact angle with water is greater than 150° is a superhydrophobic surface. Superhydrophobic surfaces are gradually attracting widespread attention because of their unique self-cleaning properties and potential applications. The basic principle of superhydrophobic surface self-cleaning is to construct a rough structure on the surface of low surface energy materials or to modify low surface energy materials on the surface of rough structures, so that water dr...
