Problems solved by technology

Since the focused ion beam uses a focused method to concentrate heat to the processing part to melt the metal, this will cause a large heat-affected zone in the surrounding parts, and the metal is prone to local burning, which is not conducive to subsequent processing.
According to the existing technology, it is directly combined with the surface of the metal substrate through plastic injection molding, and the bonding strength is relatively limited, and it is difficult to achieve an ideal level.

Abstract

The invention discloses a preparation method of a composite material, as well as a porous metal modifier. The method comprises the following steps: 1) forming a porous metal base material through a powder metallurgy sintering technology, wherein the surface of the porous metal base material has micrometer-scale holes; 2) performing surface treatment to the porous metal base material through the porous metal modifier; and 3) injection-molding the metal base material treated by the porous metal modifier, and plastic, to obtain a metal-plastic integrated composite material. The porous metal modifier contains an organic ester and organic acid blend for improving the surface tension coefficient difference of the metal base material and the plastic. According to the porous metal modifier, the bonding strength of the metal and plastic can be effectively enhanced.

Description

technical field [0001] The invention relates to a method for preparing a porous metal modifier and a composite material. Background technique [0002] Treating the surface of the metal substrate with a chemical treatment liquid can form irregular holes on the surface of the metal substrate, and then perform integral molding with plastic to prepare a composite material. Because the chemical treatment liquid generally contains strong acid, strong alkali and other chemical reagents, the waste liquid increases the treatment cost to a large extent, and there are many difficulties in the treatment of the waste liquid. [0003] There is a composite material method that etches a metal surface by a focused ion beam to form a nanohole lattice, and then integrates it with a resin. Since the focused ion beam uses a focused method to concentrate heat to the processing part to melt the metal, this will cause a large heat-affected zone in the surrounding parts, and the metal is prone to l...
