NOVELTY - Preparing stainless steel-copper-titanium graphene pot composite board comprises e.g. (i) taking the pot body composite copper plate, (ii) performing laser punching on the three-dimensionally graphitized area of the copper plate of the composite pot body by laser punching device to form number of regular groove bodies, (iii) preparing graphene-aluminum powder mixture filler by multi-stage resident dispersion device, (iv) dividing graphene-aluminum powder mixture filler that into the tank body that forms by scraping, (v) cooling the composite copper plate of the pot body, (vi) cross-linking graphene dispersion with the graphene-aluminum powder mixture filler on the upper and lower surfaces, (vii) laminating titanium plates and stainless steel plates on the upper and lower surfaces of the composite copper plate of the pot body, (viii) pressing and flattening the three-layer laminated board with press, and (ix) cold-rolling and calendaring after the clad slab is hot-rolled and clad. USE - The method is useful in medical instrument or substitute for human body in medicine. ADVANTAGE - The method enables forming the two-dimensional graphene layer area and the three-dimensional layer area on the middle layer of the composite board, so that the heat conducting coefficient of the board corresponding to the side wall of the pot body is increased, reduces the non-uniformity of heat conduction between pot body and side wall, and prevents graphene agglomeration after coating the graphene monomer. The method allows the aluminum powder and the graphene powder to be fully dispersed in the powder particle suspension region, so as to adsorbed on the monomer, and prevents the agglomersation of the powder particles. DETAILED DESCRIPTION - Preparing stainless steel-copper-titanium graphene pot composite board comprises e.g. (i) taking the pot body composite copper plate, and designing two-dimensional graphene layer area and three-dimensional graphite layer area on the pot body composite copper plate, (ii) performing laser punching on the three-dimensionally graphitized area of the copper plate of the composite pot body by laser punching device to form number of regular groove bodies, (iii) preparing graphene-aluminum powder mixture filler by multi-stage resident dispersion device, (iv) dividing graphene-aluminum powder mixture filler that into the tank body that forms by scraping, placing the composite copper plate of the pot body into the melting furnace after scraping each time, melting the aluminum powder for 3-5 minutes at temperature of 680-720℃, cooling cross-linking, repeatedly scraping until when the graphene-aluminum powder mixture filler in the tank is on the same plane as the top surface of the corresponding tank, spraying the graphene dispersion on the upper surface of the composite copper plate of the pot body when the composite copper plate of the pot body is cooled to 120-160℃ after the aluminum powder is melted, (v) cooling the composite copper plate of the pot body, and spraying the graphene dispersion on the lower surface of the composite copper plate of the pot body, (vi) cross-linking graphene dispersion with the graphene-aluminum powder mixture filler on the upper and lower surfaces of the three-dimensional graphene layer region to form uniform three-dimensional thermally conductive graphene network, and forming two-dimensional heat-conducting graphene mesh film on the upper and lower surfaces of the two-dimensional graphene layer region of the composite copper plate of the pot body by graphene dispersion, (vii) laminating titanium plates and stainless steel plates on the upper and lower surfaces of the composite copper plate of the pot body, (viii) pressing and flattening the three-layer laminated board with press, sealing the gap between the peripheral plates of the three-layer laminated board by means of inert gas shielded welding under the pressing machine, simultaneously raising the temperature, getting rid of the air between the three-layer laminated boards, and obtaining the composite plate blank, and (ix) cold-rolling and calendaring after the clad slab is hot-rolled and clad, and stress relieving in sequence, and obtaining the finished composite plate.
