Stainless steel and aluminum composite material and preparation method thereof

Abstract

The invention relates to a stainless steel and aluminum composite material and a preparation method thereof. The preparation method comprises the following steps: performing surface roughening treatment on stainless steel and aluminum after drying treatment; the preparation method comprises the following steps: mixing MXene with alcohol in proportion to obtain a uniformly dispersed MXene solution; an MXene solution is evenly sprayed to the textured aluminum surface, and after alcohol is volatilized, an aluminum plate with the surface covered with MXene is obtained; the textured stainless steel is placed on the upper side and the lower side of the aluminum plate with the surface covered with the Mxene, and a laminated sample of the stainless steel, the Mxene, the aluminum plate, the Mxene and the stainless steel which are sequentially distributed is obtained; carrying out preheating treatment on the laminated sample; and carrying out rolling compounding on the preheated laminated sample to obtain the high-thermal-conductivity metal composite material. Compared with the prior art, the preparation method has the advantages that the preparation process is not complicated, and the heat-conducting property of the prepared composite material is superior to that of a traditional mode.
