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 and a metal wetting agent. The method comprises the following steps: (1) carrying out surface laser treatment on a metal substrate so as to form fine holes; (2) carrying out surface treatment on the metal substrate with the fine holes by virtue of the metal wetting agent; (3) carrying out injection molding on plastic and the metal substrate processed by virtue of the metal wetting agent so as to form the composite material integrating metal and the plastic. The metal wetting agent contains an organic acid agent for improving the difference of surface tension coefficients of the metal substrate and the plastic. By virtue of the metal wetting agent, the bonding strength of the metal and the plastic can be effectively improved.

Description

technical field [0001] The invention relates to a method for preparing a metal wetting agent 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 has been a method of etching a metal surface by a focused ion beam to form a nanohole lattice, and then integrating 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 local burning, w...
