The utility model discloses an efficient self-heat-preservation combined assembly type wallboard structure and an energy-saving wall body structure comprising the same, the efficient self-heat-preservation combined assembly type wallboard structure comprises a wallboard body and a plurality of connecting tie pieces, the wallboard body comprises an inner side self-heat-preservation wallboard, an efficient heat preservation layer and an outer side self-heat-preservation wallboard which are sequentially arranged from inside to outside, and the connecting tie pieces are connected with the inner side self-heat-preservation wallboard, the efficient heat preservation layer and the outer side self-heat-preservation wallboard. The heat conductivity coefficient of the efficient heat preservation layer is superior to that of the inner side self-heat-preservation wall plate and that of the outer side self-heat-preservation wall plate, the fireproof grades of the inner side self-heat-preservation wall plate and the outer side self-heat-preservation wall plate both reach A2 or above, the compressive strength of the outer side self-heat-preservation wall plate reaches 0.30 MPa or above, the thickness of the outer side self-heat-preservation wall plate is 50 mm or above, and the compressive strength of the inner side self-heat-preservation wall plate reaches 3.5 MPa or above. The fireproof and heat-insulating effects are met; the overall bending resistance, fracture resistance and other properties are improved; and the safety and the stability of the efficient self-insulation combined assembly type wallboard structure are greatly improved.

The application provides a preparation method of lightweight high-strength hybrid aerogel with controllable electromagnetic performance. The aerogel prepared by molecular structure design of a crosslinking system and a normal-pressure drying method has controllable micro-nano scale pore size, excellent process performance, forms a more stable three-dimensional network structure, and can meet the integrated requirements of heat insulation and wave absorption of large-area thermal protection materials of aircrafts.
