Abstract

The embodiment of the invention discloses an activated carbon coating and a preparation method thereof and relates to the field of coating preparation. The activated carbon coating disclosed by the invention is prepared from the following raw materials in parts by weight: 50-80 parts of powdered activated carbon, 20-40 parts of resin mixture, 1-20 parts of nanometer titania and 10-20 parts of adhesive. The coating disclosed by the invention has the advantages ofexcellent selectivity, high adsorbing capacity, high adsorption speed, abrasion resistance, corrosion prevention, excellent antibacterial effect, is suitable for sewer lines, kitchen and bath articles, household products, and the like, and is an ideal odor-removing product.

Description

technical field [0001] The invention relates to an activated carbon coating and a preparation method thereof, belonging to the field of coating preparation. Background technique [0002] Modern urban residents spend a long time indoors, indoor air pollution caused by various new materials, building additives and decoration. In addition, the peculiar smell in the sewer pipe is heavy, and bacteria breed, which is harmful to the human body. Existing air purification products have poor effect, short duration, relatively limited absorption range, and poor pertinence. [0003] Activated carbon has strong physical adsorption and chemical adsorption functions, and has good adsorption capacity for gases, inorganic or organic substances in solutions, and colloidal particles. It is an adsorbent with excellent performance. Activated carbon material has stable chemical properties, high mechanical strength, acid resistance, alkali resistance, heat resistance, insoluble in water and orga...
