Abstract

The invention relates to an activated carbon binder and a preparation method thereof. The binder comprises the following components in percentage by mass: 40-60% of water, 1-5% of a cross-linking agent, 1-5% of a modifier, 0.5-1.5% of a flexibilizer, 10-40% of polyvinyl alcohol, 5-15% of emulsified silicone oil and 10-30% of potassium hydroxide. According to the invention, the activated carbon binder is prepared from substances without asphalt components, and is safe and environmentally friendly; the main component of the binder is a solid mixture, so that the binder is convenient to package,transport and store; during use, preparation is carried out by using water according to an operation process, and the binder is simple and convenient to use and easy to operate; and the binder contains KOH which is an ideal activator for preparing super activated carbon by an alkali activation method, and the binder can be used as a forming aid, also has the function of promoting an activation reaction, and has a promotion effect on formation of an activated carbon pore system.

Description

technical field [0001] The invention relates to a binder, in particular to an environment-friendly multifunctional activated carbon binder and a preparation method thereof. Background technique [0002] With the development of economy and society, various environmental pollution problems such as air and water pollution are becoming more and more serious. As an efficient adsorption material, activated carbon is more and more widely used in environmental governance, and its demand continues to increase. Its application fields include home appliance industry, food industry, medical and health care, chemical industry, metallurgical industry, pharmaceutical industry and many other industries. Compared with powdered activated carbon, shaped activated carbon has the advantages of easy modulation and processing, high density, high thermal conductivity, high strength, no dust pollution, and high adsorption capacity per unit volume. Its shape is honeycomb, ribbon, columnar, and spheri...
