Abstract
The invention relates to modified active carbon capable of absorbing electromagnetic waves. The modified active carbon is prepared by the following raw materials in parts by weight: 25 to 30 parts of wheat bran, 100 to 110 parts of active carbon, 10 to 15 parts of calcium sulfite, 3 to 5 parts of nano titanium dioxide, 8 to 10 parts of bentonite, 5 to 8 parts of cetyl trimethyl ammonium bromide, 2 to 4 parts of lauryl amine, 4 to 7 parts of polyving alcohol, 3 to 5 parts of tetraethoxysilane, 8 to 10 parts of silicon dioxide powder, 5 to 8 parts of zinc stearate, 4 to 5 parts of modified diatomite and an appropriate amount of water. The active carbon which is produced by utilizing the wheat bran has a developed porous structure, large specific surface area and high adsorption speed, and the character of the single active carbon can be changed; by utilizing the nano titanium dioxide, the electromagnetic waves can be absorbed; by utilizing the bentonite, the catalytic performance and the adhesion performance can be improved; by utilizing the polyving alcohol, the adhesive force is increased, and difficulty in disintegration is realized; meanwhile, by utilizing the calcium sulfite, the chloride can be removed. The modified active carbon has multiple functions, is wide in use and can be used for purifying the daily air and the water and also can be used for the industry.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of electromagnetic wave absorption modified activated carbon and preparation method thereof.
Background technology
Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face to people's life.
