Abstract
The utility model discloses a graphite flake is with protection sticky tape, including transparent PET membrane, black coating, PET from type membrane, the agent of acrylic acid gluing and thermal film, transparent PET membrane is the base film to coating one deck black coating, and pass through the agent of acrylic acid gluing and leave type membrane bonding with PET, and leave the epimembranal compound thermal film of type at PET. The utility model discloses have good tensile strength and excellent mechanical properties, aging resistance, temperature toleration, radiating effect are good, have guaranteed the life of sticky tape and graphite flake.
Description
Technical field
The utility model relates to a kind of graphite flake protective tapes.
Background technology
Along with the universal of electronic product and product are to the development in high integration, high computing field, wasted power doubles thereupon, more and more higher to cooling requirements.And graphite flake is widely used in electronic manufacture manufacture field due to the heat-conductive characteristic of its excellence, heat radiation as CPU all needs to carry out auxiliary heat dissipation by it, but graphite flake itself belongs to more crisp object, physical strength is low in heat radiation, graphite flake is caused to there is very large difficult point in processing and use procedure.So, be badly in need of aly there is the alignment of close, the hot coefficient of color is low, mechanical property is high strengthening membrane protecting, be convenient to processing and the use of graphite flake.Existing adhesive tape viscosity instability, non-refractory, ageing-resistant performance are not good, and radiating effect is poor, occurring that after the use of certain hour viscosity is inadequate, causing obscission, thus losing provide protection, even can destroy the normal use of body.
Summary of the invention
The purpose of this utility model is that providing a kind of has good tensile strength and the mechanical property of excellence, ageing resistance, temperature tolerance, good heat dissipation effect, ensure that the graphite flake protective tapes in the work-ing life of adhesive tape and graphite flake.
In order to achieve the above object; the technical solution of the utility model is: a kind of graphite flake protective tapes; comprise transparent PET film, black coating, PET release film, vinylformic acid sizing agent and heat dissipation film; described transparent PET film is basement membrane; and apply one deck black coating; and by vinylformic acid sizing agent bonding with PET release film, and on PET release film composite radiating film.
After adopting said structure, the utility model is basement membrane owing to adopting transparent PET film, and applies one deck black coating, has certain tensile strength and the mechanical property of excellence, can play a protective role to graphite flake.Be coating with vinylformic acid sizing agent, because it can design and stable peeling force, vinylformic acid sizing agent can be made to meet different tack requirements and service requirements.Meanwhile, this sizing agent has excellent ageing resistance, temperature tolerance, ensure that the work-ing life of adhesive tape and graphite flake.PET release film plays the effect of protection vinylformic acid sizing agent, and heat dissipation film, in order to energy rapid heat dissipation, is conducive to heat conduction to graphite.
Accompanying drawing explanation
Fig. 1 is laminate structure schematic diagram of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Shown in Figure 1; a kind of graphite flake protective tapes; comprise transparent PET film 1, black coating 2, PET release film 3, vinylformic acid sizing agent 4 and heat dissipation film 5; described transparent PET film 1 is basement membrane; and apply one deck black coating 2; and by vinylformic acid sizing agent 4 bonding with PET release film 3, and on PET release film 3 composite radiating film 5.
Shown in Figure 1, the utility model adopts the PET film 1 of black coating 2 to be basement membrane, is coated with the vinylformic acid sizing agent 4 designing viscosity on coating machine, and then the PET release film 3 in one deck protecting glue face of fitting, and compound one deck heat dissipation film 5.Adopt transparent PET film 1 to be basement membrane, and apply one deck black coating 2, there is certain tensile strength and the mechanical property of excellence, can play a protective role to graphite flake.Be coating with vinylformic acid sizing agent 4, because it can design and stable peeling force, vinylformic acid sizing agent 4 can be made to meet different tack requirements and service requirements.Meanwhile, this sizing agent has excellent ageing resistance, temperature tolerance, ensure that the work-ing life of adhesive tape and graphite flake.PET release film 3 plays the effect of protection vinylformic acid sizing agent 4, and heat dissipation film 5, in order to energy rapid heat dissipation, is conducive to heat conduction to graphite.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
