The invention relates to an SO2 filtering material, in particular to an automobile air conditioner filter carbon-clamping cloth and a preparation method thereof, and the automobile air conditioner filter carbon-clamping cloth is formed by sequentially overlapping and bonding an aggregate, a first hot melt adhesive net film, a first activated carbon layer, a silk screen, a second activated carbon layer, a second hot melt adhesive net film and melt-blown cloth; the first activated carbon layer is soaked in a nitric acid solution; and the second activated carbon layer is loaded with an active component. Compared with the prior art, the problems that in the prior art, the uniformity of a carbon layer in a carbon clamping cloth material is not high, the thickness deviation is large, the resistance is high, and high initial treatment efficiency and high adsorption capacity cannot be achieved at the same time when SO2 pollutants are treated are solved, and the carbon clamping cloth material can obtain high initial SO2 removal efficiency and high SO2 adsorption capacity at the same time.

    本发明涉及一种SO2过滤材料,具体涉及一种汽车空调过滤器夹炭布及其制备方法,由骨材、第一热熔胶网膜、第一活性炭层、丝网、第二活性炭层、第二热熔胶网膜和熔喷布依次叠合并粘结而成;所述的第一活性炭层经硝酸溶液浸泡处理;所述的第二活性炭层负载有活性组分。与现有技术相比,本发明解决现有技术中夹炭布材料中炭层均匀性不高、厚度偏差大,阻力高,且处理SO2污染物无法同时达到高初期处理效率和高吸附容量的问题,本发明的夹炭布材料可同时获得高的初期SO2去除效率和高的SO2吸附容量。
