Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
One of the core ideas of the utility model lies in that a red reinforcement membrane is provided, include from type layer 3, at least one deck polyimide film 1 and at least one deck red glue film 2, polyimide film 1 with red glue film 2 is range upon range of setting in turn, from the type film with polyimide film 1 passes through state red glue film 2 bonds. The problems of high cost, unadjustable hardness and strength, poor smoothness and single color of a single-layer red polyimide reinforcing film can be solved. And adjusting the thickness and color of the polyimide film 1 and the glue layer according to the requirements of the hardness, strength and chromaticity of the reinforced film to obtain the required red reinforced film product.
Referring to fig. 1-3, a red reinforcement film of the present invention is shown, which may specifically include: release layer 3, at least one deck polyimide film 1 and at least one deck red glue film 2, polyimide film 1 with red glue film 2 is the range upon range of setting in turn, release the membrane with polyimide film 1 passes through it bonds to state red glue film 2. Specifically, the red reinforcing film comprises a PI film (polyimide film 1), a red glue layer 2 and a release layer 3, wherein the red glue layer 2 is coated on the outer surface of the PI film, and the release layer 3 is adhered to the red glue layer 2; the PI film and the red glue layer 2 can be repeatedly adhered by a single layer or a plurality of layers, and the last layer is adhered with a release layer 3.
Referring to fig. 1, a red reinforcement film in an embodiment of the present invention is shown, including a release layer 3, a polyimide film 1 and a red glue layer 2, the release film is adhered to the polyimide film 1 through the red glue layer 2.
Referring to fig. 2, a red reinforcement film in another embodiment of the present invention is shown, including a release layer 3, two layers of polyimide films 1 and two red glue layers 2, the polyimide films 1 and the red glue layers 2 are stacked in turn, the release film and the polyimide films 1 are bonded through the red glue layers 2.
Referring to fig. 3, a red reinforcement film in another embodiment of the present invention is shown, including a release layer 3, a three-layer polyimide film 1 and three red glue layers 2, the polyimide film 1 and the red glue layers 2 are stacked in turn in sequence, the release film and the polyimide film 1 are bonded through the red glue layers 2.
