Description
Technical field
The utility model relates to silica gel piece technical field more particularly to a kind of heat-conducting silica gel sheets of high intensity.
Background technique
With the development of industrial production and science and technology, people constantly propose new requirement to material.It is led in electronic apparatus
Domain, due to the rapid development of integrated technology and package technique, electronic component, logic circuit develop to light, thin, small direction, hair
Heat is consequently increased, to need the insulating materials of high thermal conductivity, the effective heat for removing electronic equipment and generating, this is related to
The service life of product and the reliability of quality.
Common cooling means had in the past: natural cooling, ventilation use bigger casing.As heating region is more next
Wider, the heat of generation is also increasing, and electronic equipment manufacturer is forced to have to take more efficiently cooling measure.Thermal conductive silicon
Glue gasket is exactly a kind of most common auxiliary heat dissipation material.
Heat conductive silica gel gasket is widely used as sealant and is used in electronic product, therefore to heat conductive silica gel gasket in addition to heat passes
It is outer to lead requirement, it is also necessary to which heat conductive silica gel gasket has good mechanical strength.And the mechanical strength of most of heat conductive silica gel gaskets
It is poor.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of high-intensitive of proposition is led
Hot silica gel piece.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of heat-conducting silica gel sheet of high intensity, including upper film, glass fiber net and lower film, the glass fiber net are located at upper film
Between lower film, glass fiber net surface layer is coated with heat-conducting layer, upper film and lower film and is connected as one through mesh on glass fiber net.
Preferably, the glass fiber net is wavy, and glass fiber net is completely enclosed between film and lower film.
Preferably, the surface layer of the glass fiber net is adsorbed with copper powder, and copper powder is uniformly distributed.
Preferably, the mesh of the glass fiber net is square, and mesh side length is between 0.5-0.7mm.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, due to upper film and
It is provided with glass fiber net between lower film, the tensile strength of film and lower film can be improved, promotes pull resistance, and glass fiber net is set
It is set to waveform, it is possible to increase the contact area of glass fiber net and upper film and lower film, and then film and lower film are promoted indirectly
Through the contact area of mesh, adhesion strength is improved, is not easily disconnected from, while copper powder is attached on glass fiber net, can reduce due to glass
Influence of the presence of net to thermal conductivity improves thermal conductivity indirectly, and copper powder outer ring is wrapped in film and lower film, no
The case where will appear conduction, electric leakage.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram.
In figure: upper film 1, glass fiber net 2, lower film 3.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of heat-conducting silica gel sheet of high intensity, including upper film 1, glass fiber net 2 and lower film 3, glass fiber net 2
Between upper film 1 and lower film 3,2 surface layer of glass fiber net is coated with heat-conducting layer, upper film 1 and lower film 3 and surfs the Internet through glass fiber net 2
Hole is connected as one.
Glass fiber net 2 is wavy, and glass fiber net 2 is completely enclosed between film 1 and lower film 3, increase glass fiber net 2 with
The contact area of upper film 1 and lower film 3, and then film 1 and lower film 3 are promoted indirectly through the contact area of mesh, it mentions
High bond strength.
The surface layer of glass fiber net 2 is adsorbed with copper powder, and copper powder is uniformly distributed, improve thermal conductivity, avoid the transmitting of heat by
The isolation of glass fiber net 2.
The mesh of glass fiber net 2 is square, and mesh side length is between 0.5-0.7mm.
In this case, due to being provided with glass fiber net 2 between upper film 1 and lower film 3, film 1 and lower film 3 can be improved
Tensile strength promotes pull resistance, and glass fiber net 2 is set as waveform, it is possible to increase glass fiber net 2 and upper film 1 and lower film 3
Contact area, and then film 1 and lower film 3 are promoted indirectly through the contact area of mesh, adhesion strength is improved, is not easy to take off
From while copper powder is attached on glass fiber net 2, can be reduced influence of the presence due to glass fiber net 2 to thermal conductivity, be improved indirectly thermally conductive
Property, and copper powder outer ring is wrapped in film 1 and lower film 3, the case where being not in conduction, leak electricity.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
