Aerogel heat preservation sandwich composite wallboard

The utility model relates to an aerogel high-strength heat-preservation sandwich composite wallboard, which aims to solve the technical problem that the aerogel heat-preservation effect is reduced due to the fact that the sealing performance of the current composite wallboard is poor, and comprises a composite board body, and the composite board body comprises a clamping board A, a clamping board B and a supporting assembly. A connector A, a connecting groove A, a connector B and a connecting groove B are formed in a clamping plate A and a clamping plate B of the composite wallboard respectively, so that when the composite wallboard is installed, a sliding block A and a sliding block B of a previous composite board body are connected with a sliding groove A and a sliding groove B of a next composite board body; and the fixing block A and the fixing block B of the previous composite board body are connected with the fixing groove A and the fixing groove B of the next composite board body, so that the sealing p
