Abstract

The invention discloses a treating solution for nanometer holes in the stainless steel surface and an application method of the treating solution. The treating solution comprises, by volume, 1,000 parts of deionized water, 10-120 parts of organic acid, 30-230 parts of a halogen-containing inorganic acid solution and 30-200 parts of a KNO3 or NH4NO3 solution. The method for applying the treating solution to obtain the nanometer holes comprises the steps that firstly, the deionized water is used for conducting ultrasonic cleaning on the metal surface; secondly, grinding and polishing are conducted through abrasive paper; and thirdly, the temperature and the time of the treating solution are synchronously controlled. A prepared stainless steel surface nanometer hole structure belongs to the key index in plastic-metal integrated composite forming, and it becomes possible for the plastic-metal integrated composite technology to bear structural pieces with high loads.

Description

technical field [0001] The invention relates to metal surface treatment technology, especially based on the concept of NMT (nano-injection molding technology) technology, a nano-hole structure is prepared on the surface of a stainless steel substrate, so that it can be integrated with plastics without relying on adhesives. In particular, it relates to a stainless steel surface nano hole treatment liquid and an application method. Background technique [0002] Based on plastic-metal integrated composite molding technology, after forming nano-holes on the metal surface, through a certain pressure, the plastic melt enters the nano-hole structure on the metal surface to form a microscopic mechanical interlock, which greatly enhances the plastic and metal. Bond strength. Due to the difficulty in preparing the nano-pore structure on the surface of stainless steel, the integrated composite molding of stainless steel substrate and plastic is more difficult. Most of the metal sub...
