Accompanying drawing explanation
Fig. 1 is the floor map of a specific embodiment of shading damping foam of the present invention;
Fig. 2 is the shading glue belt of shading damping foam of the present invention transmitance-wavelength curve figure under visible ray.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic procedure of the present invention, structure are only described in a schematic way, so it only show the formation relevant with the present invention.
The technical scope of this invention 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 invention 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.
