Abstract
The invention discloses an antibacterial mildew-resistant modified active carbon filter material, which is characterized by being composed of the following raw materials in parts by weight: 135 to 145 parts of coconut shell active carbon, 2 to 3 parts of gypsum, 3 to 4 parts of potassium carbonate, 2 to 3 parts of citric anhydride, 5 to 7 parts of ethanol, 4 to 6 parts of konjak powder, 3 to 4 parts of maltose syrup, 30 to 38 parts of corn straw, 12 to 15 parts of kaolin, 9 to 12 parts of silicon carbide, 2 to 3 parts of calcium sulfate, 0.5 to 0.8 part of calcium propionate, 4 to 6 parts of adsorption auxiliary agent, and a proper amount of water. In the preparation method, the corn straw powder, kaolin, and other chemical components carry out reactions, then the reaction product and active carbon are activated together, not only the harmful gases can be eliminated, but also the raw material utilization rate is increased; the space for stacking the straws is saved, moreover, calcium sulfate and calcium propionate are added to prevent mildew, bacteria, and dampness, the service life of active carbon is prolonged, and the filter material can be made into air purification facilities such as air conditioner filter screen, and the like.
Description
Technical field
The present invention relates to a kind of filtering material and preparation method thereof, particularly a kind of have activated charcoal filter material of the modification of antibacterial and mouldproof effect and preparation method thereof.
Background technology
Along with the fast development of society, environmental pollution is also on the rise, and Gong industry Fei Qi ﹑ vehicle exhaust etc. seriously annoyings the life of the mankind.There is new cognition to the pure and fresh degree of air, had higher requirement to air-filtering ability.Modal have filtering material for air handling system, present ambient air pollutes very serious, haze weather has brought great harm, air adsorption filtering material can by the various deleterious particle things of air, as PM2.5 absorption, prevent the life or the working environment that enter people, reduce human lung to the suction of the harmful substances such as particle, improve the quality of life of people, reduce the generation of disease.Existing filtering material mainly contains ceramic honey comb, filter paper, active carbon, steel wire etc.And at present the clamping active carbon nonwoven fabric filtering material produced of general industry mostly adsorption rate is lower, Organic gas can only be removed, as toluene etc., cannot the alkaline or compound volatile harmful gas of adsorb acidic effectively, or part is still rested in active carbon hole by the foul smell adsorbed, even if can spin off again after a period of time, can not be removed.So general filtering material is not high for the clearance of foul smell in air yet.Active carbon with high specific surface area has loose structure, can adsorb various organic matter and inorganic matter, and having the advantages that adsorption capacity is large, adsorption rate is fast, is a kind of high-efficiency adsorbent of high-quality, is widely used in the every field such as food industry, chemical industry and environmental protection.
Summary of the invention
