The invention discloses a novel high-strength polymethyl methacrylate composite board which comprises a base board and two reinforcing layers, wherein a plurality of groups of connecting blocks are fixedly arranged on the upper surface and the lower surface of the base board, the plurality of groups of connecting blocks are uniformly laid on the surface of the base board, the two reinforcing layers are arranged in two groups, the two reinforcing layers are symmetrically arranged on the upper side and the lower side of the base board, a plurality of groups of connecting grooves are uniformly formed in the two reinforcing layers, the connecting blocks are fixedly arranged in the connecting grooves, a sound insulation layer is fixedly arranged on the outer surface of one group of reinforcing layers, a heat insulation layer is fixedly arranged on the outer surface of the other group of reinforcing layers, and a first polymethyl methacrylate layer is fixedly arranged on the. According to the invention, the reinforcing layer is arranged, so that the overall structural strength of the plate is increased, and the connection stability is increased and the strength of the plate is further improved through the design of the connecting block and the connecting groove. |
