Problems solved by technology

However, for stainless steel, the electrochemical anodizing solution will form a dense oxide film on the surface of the stainless steel, which is not conducive to the formation of nanopores, so that the bonding strength of the prepared composite material is very limited, and the production cost is high and energy consumption is high. larger
[0005] In addition, there is a method to treat stainless steel by anodizing to form a porous film, and then integrate it with resin; The formation of porous membrane; and additional capital investment in equipment is required in anodizing treatment, which increases the cost of production to a certain extent

Abstract

The invention discloses a preparing method for a composite body metal material. The preparing method comprises the following steps that firstly, stainless steel is pretreated, a plurality of holes are formed in the surface of the stainless steel through a puncher, 50-80 holes are formed in each square meter, and the diameter of the holes ranges from 10 mm to 40 mm; secondly, the stainless steel in which the holes are punched in the first step is immersed in a metal treating agent to be subjected to surface chemical treatment; and thirdly, the stainless steel, plastic raw materials and filler are mixed together to be subjected to injection molding, the injection molding temperature ranges from 800 DEG C to 1,000 DEG C, and the composite body metal material in which stainless steel and plastic are integrated is formed. In the pretreatment process, the tiny irregular holes are formed in the surface of the stainless steel, accordingly, organic ammonium salt and an organic acid agent in the metal treating agent are more closely fused with a stainless steel base material, the combining effect of the stainless steel, the plastic and the filler is better, and the tenacity of the stainless steel is higher.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a preparation method of composite metal materials. Background technique [0002] The traditional preparation technology of stainless steel and plastic composites is generally realized by setting a fixed structure between the stainless steel structural parts and the plastic parts, which requires adding a connection structure to the stainless steel structural parts; but the processing efficiency of stainless steel is relatively low, And it is impossible to make structures with complex shapes, which greatly limits the application of stainless steel structural parts in electronic products, precision medical equipment, and automobile body parts. [0003] Although the integrated combination of stainless steel and plastic can be realized by hot melt adhesive bonding at present, the bonding force between plastic and stainless steel is not high, which cannot meet the actual use ...
