Activated carbon foam prepared from activated carbon absorbing waste gas in polyurethane foaming process and preparation method thereof

The invention discloses activated carbon foam prepared from activated carbon absorbing a waste gas in the polyurethane foaming process and a preparation method thereof. The activated carbon foam is prepared by reaction of the activated carbon absorbing the waste gas in the polyurethane production process with high-activity polyol, toluene diisocyanate and water. According to the invention, the activated carbon absorbing the waste gas in the polyurethane foaming process is taken as a raw material, so that the cost is low and is far lower than the cost for manufacturing the activated carbon conventionally. At the same time, raw materials adsorbed in the activated carbon participate in the reaction, and the utilization rate of the raw materials in the production process is fully improved. 本发明公开了一种利用聚氨酯发泡过程中吸收废气的活性炭制备的活性炭泡沫及制备方法，由聚氨酯生产过程中吸收废气的活性炭与高活性多元醇、甲苯二异氰酸酯及水反应制得。本发明以聚氨酯发泡过程中吸收废气的活性炭为原料，具有成本低廉，远低于常规制造活性炭的费用。同时，活性炭中吸附的原料参与反应，也充分提高了生产过程中的原料利用率。
