The invention discloses a laminate composite board with a good thermal insulation effect. The laminate composite board comprises a board body, wherein water pipes are fixed at the central axis position of the inner wall of the top end of the board body and contain a transverse water pipe and a vertical water pipe; water outlets are respectively formed in the outer walls of two sides of the vertical water pipe; in addition, sprinkler heads sleeve the inner walls of the water outlets; connecting rods are welded to the outer walls of two sides of the water pipe; besides, a first thermal insulation layer is fixed on the outer wall of one side, away from the water pipes, of one connecting rod by bolts; the outer wall of the top end of the first thermal insulation layer is fixed on the inner wall of the top end of the board body by bolts. According to the laminate composite board disclosed by the invention, transparent conducting films are added on the outer layers of two sides of the boardbody and are fixed with a woven wire mesh blanket through current conducting rods, so that static electricity on the wall surface can be effectively removed; the water pipes are added in the board body for self-extinguishing fire during outbreak of fire; the thermal insulation layer and a sound insulation layer are added on two sides of the board body, so that heat insulation and sound insulationfor the indoor can be effectively realized.
