Abstract
The invention belongs to the technical field of polymer composite material synthesis, relates to the preparation of a carbon fiber-polyurethane porous foamed material, and especially relates to a preparation method and applications of a Mg/Al/C fiber-polyurethane foamed material. The preparation method comprises the following steps: preparing a Mg/Al/C fiber material, subjecting the Mg/Al/C fiber material to hydrophobic modification, mixing hydrophobic Mg/Al/C fibers, polyether polyol NJ-330, a foaming agent, a foam stabilizer, and a catalyst at a room temperature under stirring, adding toluene diisocyanate, and carrying out one-step foaming method to obtain the foamed material. Vinyl triethoxysilane is used to carry out hydrophobic modification on the Mg/Al/C fiber material; the Mg/Al/C fiber powder is uniformly dispersed into a foamed material, the oil absorbing performance, anti-aging property, and thermal stability of the foamed material are enhanced, and the comprehensive performance of the foamed composite material is improved. Trichloromethane is taken as the adsorption object, and the test results show that the foamed material has a good oil absorbing and eliminating effect, so the foamed material can be used to process petroleum leakage, organic solvent pollution, and the like, the operation is simple, and the adsorption rate is high.
