Abstract

The invention relates to a polymethyl methacrylate and polycarbonate composite board which comprises a polymethyl methacrylate layer. The upper layer and the lower layer of the polymethyl methacrylatelayer are respectively covered with an upper polycarbonate layer and a lower polycarbonate layer; the polymethyl methacrylate layer is attached to the matte surface of the joint surface of the upperpolycarbonate layer and the lower polycarbonate layer in a thermal attachment manner; the invention relates to a preparation method of a polymethyl methacrylate and polycarbonate composite board. Thepreparation method comprises the following steps: (1) respectively heating and melting polycarbonate and polymethyl methacrylate raw material particles in different preheaters; (2) respectively extruding polycarbonate and polymethyl methacrylate from different channels of the multilayer die head; (3) carrying out three-roller calendering molding on the extruded polycarbonate and polymethyl methacrylate; and (4) laminating and cutting a polycarbonate and polymethyl methacrylate composite board finished product. The composite board produced by the invention has the characteristic of high transparency, meets the characteristics of high chemical resistance and durability, and is wide in application range.
