Abstract
The invention discloses a thermally conductive adhesive tape. The adhesive tape comprises a transparent PET (Polyethylene Terephthalate) film layer, wherein a graphite coating layer is formed on a side surface of the transparent PET film layer, the surface of the graphite coating layer is coated with an acrylic pressure-sensitive adhesive bonding layer, and a release film layer is adhered to the surface of the acrylic pressure-sensitive adhesive bonding layer. Due to the adoption of the structure, the thermally conductive adhesive tape disclosed by the invention has the following advantages that: 1, since adhesive tape is designed to be ultra-thin, the thermal conductivity of the graphite layer are not affected; 2, when the graphite layer is subjected to die cutting, the edge-packaged design can be adopted and thus the graphite film layer has good insulativity; and 3, the adhesive tape has good insulativity for the to-be-adhered objects, such as graphite film, mobile phone back shell, mobile phone motherboard, and stainless steel fins.
Description
Technical field
The present invention relates to a kind of heat-conducting glue adhesive tape.
Background technology
At present, heat-conducting glue adhesive tape all adopts PE (polyethylene) film to use as base material, and PE film strength is poor, gain in strength and must increase film thickness, affect heat conductivity, and the high thermal resistance of PE film is poor.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, to provide a kind of heat-conducting glue adhesive tape with excellent heat conductivity and electrical insulating property.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of heat-conducting glue adhesive tape, comprise PET transparent film layer, described PET transparent film layer one side surface is provided with graphite film layer, the surface coated of described graphite film layer has acrylate pressure sensitive adhesive adhesive coating, and described acrylate pressure sensitive adhesive adhesive coating surface label is covered with release film layer.
Described graphite film layer is conductive and heat-conductive layer.
Described release film layer is PET release film layer.
Described PET transparent film layer opposite side is also provided with another layer of graphite film layer, and the surface coated of this graphite film layer has another layer of acrylate pressure sensitive adhesive adhesive coating, and this acrylate pressure sensitive adhesive adhesive coating surface label is covered with another layer of release film layer.
The present invention adopts said structure, has the following advantages: 1, adhesive tape ultrathin design, and the while does not affect the heat conductivity of graphite linings; 2, can bound edge design during graphite rete cross cutting, make graphite rete there is good insulativity; 3, the clung bodies such as graphite film and mobile phone shell on the back, cell phone mainboard, stainless steel radiator element are all had to good insulativity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;

Fig. 2 is the embodiment bis-lamination layer structure schematic diagram in the present invention;
In Fig. 1～Fig. 2,1, PET transparent film layer; 2, graphite film layer; 3, acrylate pressure sensitive adhesive adhesive coating; 4, release film layer.
Embodiment
Embodiment mono-
A heat-conducting glue adhesive tape, comprises PET transparent film layer 1 as shown in Figure 1, and PET (polyethylene terephthalate) transparent film layer 1 one side surfaces are provided with graphite film layer 2, and the conductive graphite layer that graphite film layer 2 is black, is referred to as black heat conducting film.The surface coated of graphite film layer 2 has acrylate pressure sensitive adhesive adhesive coating 3, and acrylate pressure sensitive adhesive adhesive coating 3 surface labels are covered with release film layer 4.Graphite film layer 2 is conductive and heat-conductive layer.Release film layer 4 is PET release film layer.
Adhesive tape ultrathin design, the while does not affect the heat conductivity of graphite linings.During graphite rete cross cutting, can design by bound edge, make graphite rete there is good insulativity.The clung bodies such as graphite film and mobile phone shell on the back, cell phone mainboard, stainless steel radiator element are all had to good insulativity.
Embodiment bis-
A heat-conducting glue adhesive tape, comprises PET transparent film layer 1 as shown in Figure 2, and PET (polyethylene terephthalate) transparent film layer 1 one side surfaces are provided with graphite film layer 2, and the conductive graphite layer that graphite film layer 2 is black, is referred to as black heat conducting film.The surface coated of graphite film layer 2 has acrylate pressure sensitive adhesive adhesive coating 3, and acrylate pressure sensitive adhesive adhesive coating 3 surface labels are covered with release film layer 4.PET transparent film layer opposite side is also provided with another layer of graphite film layer, and the surface coated of this graphite film layer has another layer of acrylate pressure sensitive adhesive adhesive coating, and this acrylate pressure sensitive adhesive adhesive coating surface label is covered with another layer of release film layer.Graphite film layer 2 is conductive and heat-conductive layer.Release film layer 4 is PET release film layer.
The PE base material adopting in the past can only be produced one side sealing tape, adopts now PET base material, both can produce one side sealing tape, also can produce double-faced adhesive tape.PET film is easily combined with the good graphite linings of thermal conduction, makes heat-conducting glue adhesive tape.This sealing tape has excellent thermal conductivity and electrical insulating property.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical scheme of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
