Abstract

The invention provides a non-gel high-binding-force stainless steel and plastic complex preparation method. The method comprises the steps of ultrasonic acidification treatment of stainless steel, first water pool flushing, amine system aqueous solution impregnation, second water pool flushing, drying and engineering plastic injection. A micro-porous structure is rapidly etched on the surface of the stainless steel in an ultrasonic wave and acidifying treatment combination mode, so it is convenient for the introduction of a subsequent engineering plastic to the micro-porous structure; and the amine system aqueous solution impregnation process is adopted to make amine system compound molecules simultaneously adsorbed to the micro-porous structure formed on the surface of the stainless steel in order to firmly bind the engineering plastic with the stainless steel.

Description

technical field [0001] The invention relates to composite technology, in particular to a method for preparing a composite of stainless steel and plastic without glue and with high binding force. Background technique [0002] In the manufacturing fields of automobiles, household electrical products, industrial equipment and other parts, it is usually necessary to combine stainless steel and engineering plastics together. Usually, bonding technology is used, that is, stainless steel and engineering plastics are bonded together through adhesives. Adhesive technology has developed relatively mature. For example, the Chinese invention patent application with application number 201210321030.3 provides an epoxy resin adhesive, which includes the following components: 35-45 parts by weight of epoxy resin, diethylenetriamine 4-6 parts by weight, 6-8 parts by weight of dibutyl phthalate; the Chinese invention patent application with application number 201210426791.5 discloses an epoxy...
