Abstract
The utility model relates to a heat radiation material field for the OLED screen discloses a high performance buffering heat radiation material for the OLED product, including the copper foil, copper foil one side is provided with the cotton layer of bubble that foams on the copper foil and forms, the cotton layer of bubble is kept away from copper foil one side and is provided with the sticky tape layer, the sticky tape layer is kept away from cotton layer one side of bubble and is provided with from the type layer, the utility model discloses directly foaming on copper foil 4 and having replaced the tradition and used glued membrane with copper foil 4 and bubble cotton complex, on the one hand make the cohesion between the two good, have excellent attached, the incomplete glue is difficult for tearing and coming off, the layering, the cost has been practiced thrift simultaneously, and can be as thin as 0.1mm after the shaping of this; meanwhile, the heat dissipation, buffering, water proofing, shielding and other characteristics are realized.
Description
Technical Field
The utility model relates to a heat radiation material field is used to the OLED screen, in particular to a high performance buffering heat radiation material for OLED product.
Background
As is well known, the OLED and the LCD are two different display materials, and compared with the LCD, the OLED has the advantages of a wide viewing angle, almost infinite contrast, low power consumption, very high response speed, full color, simple manufacturing process, and the like. The OLED material can be self-luminous, a backlight source is not needed to be added to an LCD, the process can be greatly simplified, the size is reduced, in addition, the blue light prevention characteristic of the OLED material enables OLED electronic products to be more and more advocated by modern people, but the market lacks an ultrathin heat dissipation, supporting and buffering integrated material for an OLED screen, and the high-performance buffering heat dissipation material in the patent can make up the vacancy.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a high-performance buffer heat dissipation material for OLED products,
the utility model provides a technical scheme that its technical problem adopted is: a high performance buffering heat dissipation material for OLED product, including the copper foil, copper foil one side is provided with the cotton layer of bubble that forms on the copper foil of foaming, the cotton layer of bubble is kept away from copper foil one side and is provided with the sticky tape layer, the sticky tape layer is kept away from cotton layer one side of bubble and is provided with from the type layer.
Further, the method comprises the following steps: the foaming resin may be acrylic, polyurethane or polyimide.
Further, the method comprises the following steps: the adhesive tape is an exhaust adhesive tape or a high-thermal-conductivity adhesive tape.
Further, the method comprises the following steps: the viscosity of the high-performance buffering heat dissipation material is larger than 1200 g/inch.
The utility model has the advantages that:
1. the structure directly foams on the copper foil to replace the traditional method that the copper foil and foam are compounded by using a glue film, so that the cost is saved;
2. the high-performance buffering heat dissipation material adhesive tape with the structure is thin to 0.1mm after being formed;
3. the high-performance buffering heat dissipation material adhesive tape with the structure has the characteristics of heat dissipation, buffering, water prevention, shielding and the like;
4. the high-performance buffering heat dissipation material with the structure has excellent adhesion, no adhesive residue and good binding force between the copper foil and the foam.
Drawings
Fig. 1 is a structural diagram of a high-performance buffer heat dissipation material for OLED products.
Labeled as: release layer 1, adhesive tape layer 2, foam layer 3, copper foil 4.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
A high performance buffering heat dissipation material for OLED product as shown in fig. 1, including copper foil 4, copper foil 4 one side is provided with the foam layer 3 that foams and forms on copper foil 4, the foamed resin can be acrylic acid, polyurethane or polyimide, foam layer 3 is provided with adhesive tape layer 2 apart from copper foil 4 one side, the adhesive tape is exhaust adhesive tape or high heat conduction adhesive tape, adhesive tape layer 2 is kept away from foam layer 3 one side and is provided with from type layer 1, and concrete production technology is: taking a copper foil 4 with the thickness of 0.018-0.050 mm as a base material, directly coating one of acrylic acid, polyurethane and polyimide foaming resin on the copper foil 4 for foaming, wherein the thickness of foam is 0.05-0.20 mm, directly coating an exhaust adhesive tape or a high-thermal-conductivity adhesive tape which is well coated on the foam surface of the foam of the copper foil 4, collecting a release layer 1, and curing to obtain the material for use;
the structure directly foams the copper foil 4 to replace the traditional glue film for compounding the copper foil 4 and foam cotton, so that on one hand, the bonding force between the copper foil 4 and the foam cotton is good, the structure has excellent adhesion, no glue residue, difficult tearing, falling and layering, and simultaneously saves the cost, and the thickness of the structure can be as thin as 0.1mm after the structure is formed; meanwhile, the heat dissipation, buffering, water proofing, shielding and other characteristics are realized.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
