Brief description of the drawings
Fig. 1 is the floor map of a detailed description of the invention of shading damping foam of the present utility model;
Fig. 2 is the shading glue belt of shading damping foam of the present utility model transmitance-wavelength curve figure under visible ray.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic procedure of the present utility model, structure are only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
As shown in Figure 1, shading damping foam 100 of the present utility model comprises: PET protective film 10, shading glue belt 20 and polypropylene shading damping foamed cotton layer 30.
Wherein, described shading glue belt 20 and polypropylene shading damping foamed cotton layer 30 are fixed on the homonymy of described PET protective film 10, and shading glue belt 20 and polypropylene shading damping foamed cotton layer 30 can be arranged to different size and shapes as required.Described shading glue belt 20 comprises: black and white substrate layer and transparent adhesive layer, described black and white substrate layer is fixed in described PET protective film by transparent adhesive layer.Described black and white substrate layer comprises black matrix layer and white substrate layer, and described black matrix layer is between described transparent adhesive layer and white substrate layer.In addition, transparent adhesive layer, adds other material of can not making dirty man-hour.Preferably, the thickness of described shading glue belt is 0.065mm.
