Normal pressure drying method for preparing melamine aerogel and fiber type clay reinforced melamine composite aerogel

The invention belongs to the technical field of material manufacturing, and discloses a method for preparing melamine composite aerogel and fiber type clay reinforced melamine composite aerogel by a normal pressure drying method. Melamine resin is used as a main material, melamine gel and fiber type clay composite reinforced melamine gel are prepared through solvent heat treatment under the acidic condition, a catalyst is washed away through an alcohol reagent, and the melamine composite aerogel which is complete in block and good in mechanical property can be obtained through normal-pressure drying. The fiber type clay is adopted to reinforce the melamine composite aerogel, and the clay can construct a double-network structure in a melamine gel network, so that the aerogel with better mechanical properties is obtained. The material can be carbonized to obtain self-supporting carbon aerogel which can be used in the fields of catalyst loading, adsorption, energy storage, heat insulation and flame retardant mat
