Embodiment 1

[0018] The preparation method of graphite material sheet is as follows:

[0019] The first step is to punch the S5002l-50 material out of the traces of the graphite shape, so as to facilitate the alignment and bonding of the graphite. When die-cutting, the knife faces the S7502L-50 rubber surface to mark the line, cut the hole completely, step 230MM, and collect the large roll;

[0020] The second step is to stick the graphite material on the weakly adhesive silica gel film by hand, and turn it into a coil state. When pasting the graphite, paste the 200*130 graphite on the S7502L-50 rubber surface according to the position of the mark line, and then paste it on the S7502L-50 rubber surface. The graphite surface is centered and compounded with 15G mesh pattern, and the large volume is collected;

[0021] The third step is to cut the graphite die into a fixed shape with the small hole sleeve line of the flat knife, and then carry out the laminating action of the double-sid...

Abstract

The invention relates to a graphite sheet material preparation method comprising the following steps that the traces of a graphite shape are formed by S50021-50 material through punching so that graphite alignment and fitting are facilitated; graphite material is adhered on a weak adhesive silica membrane by a manual rotary adhering mode so as to be changed into the coiled material state; a graphite mould is cut into fixed shapes by using plane blade hole sleeving lines, and then double-sided adhesive tape fitting motion is performed; hole positioning transferring is performed; a single-sided adhesive tape and a bearing membrane and an underlying membrane are fit; ear and tearing hand mould cutting is performed; internal holes are formed via punching through a 420 mould cutting machine, the cutter faces S7502L-25B, the holes are wholly cut, and waste material of the internal holes is punched to the internal part of the machine to be discharged via a hardware punching mould; peripheral formation is performed, the cutter faces S7502L-25B in mould cutting, cutting is performed at the upper half of 50T004 by all the cutter lines, and a large coil is retreated; waste of the machine is discharged, contour waste material of the product is removed to a material collecting shaft in a compound machine through a scraper; and independent cut sheets are formed through cutting. The preparation method is high in productivity and qualification rate.

Description

technical field [0001] The invention relates to the field of processing graphite raw material sheets, in particular to a preparation method of graphite material sheets. Background technique [0002] In the electronic communication industry organization, in order to bond the battery and the back cover, the thermally conductive part that dissipates heat is called a heat sink. Graphite flake element is an allotrope of carbon, and the periphery of each carbon atom is connected with three other carbon atoms (arranged in a honeycomb-like multiple hexagons), which are combined by covalent bonds to form covalent molecules . Graphite is an electrical conductor because each carbon atom emits an electron and those electrons are free to move. [0003] The general method of synthesizing graphite is to crystallize graphite by pyrolysis of polymer PI film. This type of graphite is used in notebook computers, high-power LED lighting, flat panel displays, digital cameras, mobile phones an...
