Problems solved by technology

Although activated carbon with high performance and low price can be successfully made with these materials, at present, these materials have a single application method, and they are only made into activated carbon with different shapes and specifications for direct application, which also limits the application of activated carbon to a large extent.

Abstract

The invention discloses a preparation method for corrosion resistance water-based paint with activated carbon as a raw material. The method comprises the steps that firstly, the activated carbon is soaked into a hydrochloric acid solution for a certain period of time and then is filtered and dried to obtain a first material; then, the first material is added into a reaction kettle, an ammonium carbonate solution is added, heating and stirring are performed, filtering is performed, and a solid substance obtained after filtering is dried to obtain a second material; then, the second material, tetrabutyl titanate, di-n-butyltin dilaurate, polyester fiber and tetraethoxysilane are added into the reaction kettle, heating and stirring are performed on the vacuum condition, then, crylic acid, barium stearate, benzyldimethylstearyl ammonium chloride, deionized water and absolute ethyl alcohol are added, continuous stirring is performed and then the temperature is decreased to reach the room temperature to obtain the corrosion resistance water-based paint with the activated carbon as the raw material. The water-based paint obtained through the preparation method has the good corrosion resistance and absorption performance, and the application range is further enlarged.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a preparation method of a corrosion-resistant water-based paint with activated carbon as a base material. Background technique [0002] Activated carbon is an amorphous structure material based on graphite microcrystals. Its main element is carbon, and there are some non-carbon elements such as oxygen, hydrogen, nitrogen, sulfur, etc. Most of them are combined at the edge of the carbon network to form surface compounds. . The biggest feature of activated carbon is that it has developed pore structure, large specific surface area and adsorption performance, and its specific surface area can be as high as 1000-3000m2 / g. These characteristics of activated carbon determine that it has a strong adsorption capacity for gases, inorganic or organic substances in solution, and colloidal particles. As an excellent adsorbent, activated carbon has a unique pore struct...
