Problems solved by technology
[0004] However, when polycarbonate resin or other types of optical plastics are used as the protective plate material of the display, it usually has the disadvantages of insufficient surface hardness and easy scratches.
[0005] In view of this, some people in the industry have developed a laminate composed of multiple layers of plastics. However, when this laminate is manufactured, the tension distribution of each plastic layer is often asymmetrical, so that the laminate often warps. quality defects

Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] Such as figure 1 As shown, an embodiment of the resin laminate 3 of the present invention is suitable for use as a display protection plate. The resin laminate 3 includes a polycarbonate resin layer 31 and a transparent thermoplastic resin layer 32. The transparent thermoplastic resin The layer 32 is bonded to one surface of the polycarbonate resin layer 31 .
[0031] In this embodiment, the transparent thermoplastic resin layer 32 is a (meth)acrylate resin layer; in other embodiments, the transparent thermoplastic resin layer 32 can also be other transparent resin materials, such as polystyrene resin, polyolefin resin, polyester resin, methyl (meth)acrylate-styrene copolymer resin, acrylonitrile-styrene copolymer resin, etc.
[0032] In this embodiment, the thickness of the resin laminate 3 is 0.75 mm to 1.2 mm, wherein the thickness of the...

Abstract
A resin laminate body comprises a polycarbonate resin layer and at least one transparent thermoplastic resin layer engaging on the surface of the polycarbonate resin layer wherein the polycarbonate resin layer has a first flow index MI1g / 10min loaded at a temperature of 230-270 degrees and a second flow index MI2g / 10min loaded at a temperature of 230-270 degrees. The first flow index and the second flow index meet type: MI2 MI1 = 5g / 10min. Through the resin laminate structure layer composed of the transparent thermoplastic resin layer and the polycarbonate resin, it is easy to produce scratch-resisting and abrasion resisting resin laminate bodies of high quality and low cost.
Description
technical field [0001] The present invention relates to a resin laminate, in particular to a polycarbonate resin laminate. Background technique [0002] In terms of the structure of the liquid crystal display, in order to avoid damage to the liquid crystal display module during transportation or use, a transparent protective plate will be attached to the display window of the liquid crystal display module to ensure the stability of its display quality. The optical materials used to make the protective plate are commonly glass, plastic (such as PET, PE, PC) and the like. [0003] Among them, polycarbonate resin (polycarbonate resin, referred to as PC), because it has excellent transparency, impact resistance, heat resistance and elasticity, and has the characteristics of light weight, low cost, mass production and rapid production, so it is often used It is used to replace glass and has been widely used in architectural decoration (such as doors and windows, lighting covers)...
