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 metal treating agent and a composite material and its preparation method. Formula of the metal treating agent is as follows: 70-240 parts by weight of organic ammonium salt and 55-160 parts by weight of an organic acid agent are added into 1,000 parts by weight of a solvent. The preparation method of the composite material comprises the following steps: firstly, stainless steel is pretreated to form multiple holes in the surface of the stainless steel; then, surface chemical treatment is carried out by putting the stainless steel into the above metal treating agent; and finally, injection moulding is carried out. The composite material is formed by integrating the stainless steel and plastic into one piece by the above preparation method. Cost and energy consumption of the stainless steel surface chemical treatment technology through the metal treating agent are low. The surface of the stainless steel which has undergone chemical surface treatment is basically not blackened, and the overall usage appearance of a product is not influenced. Meanwhile, the bonding effect of the stainless steel and plastic is good, bonding strength is high, and structure looseness is not easy to happen.

Description

technical field [0001] The invention relates to a metal treatment agent, a composite material formed of stainless steel and plastic treated with the metal treatment agent and a preparation method thereof. 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...
