Abstract

The invention discloses a preparation method for a composite material, and a liquid metal wetting agent. The method comprises the following steps: (1) carrying out laser treatment on the surface of a liquid metal base material to form fine holes; (2) carrying out surface treatment on the liquid metal base material with the fine holes by using the liquid metal wetting agent; and (3) carrying out injection molding on plastic and the liquid metal base material treated by the liquid metal wetting agent to obtain the composite material integrating liquid metal and the plastic. The liquid metal wetting agent contains an organic modifier for improving a surface tension coefficient difference between the liquid metal base material and the plastic. According to the preparation method for the composite material, and the liquid metal wetting agent, the bonding strength of the liquid metal and the plastic can be improved.

Description

technical field [0001] The invention relates to a preparation method of a liquid metal wetting agent and a composite material. Background technique [0002] Liquid metal (also known as amorphous material) has a unique microstructure of atomic arrangement in short-range order, long-range disorder, and no grain boundary. Compared with corresponding crystal materials, liquid metal has high strength, good scratch resistance, and excellent appearance. Excellent performance such as fashion and high gloss. [0003] Treating the surface of the liquid metal base material with a chemical treatment liquid can form irregular holes on the surface of the liquid metal base material, and then perform integral molding with plastic to prepare a composite material. Since the chemical treatment liquid generally contains strong acid, strong alkali and chemical modifiers of other components, the waste liquid increases the treatment cost to a large extent, and there are many difficulties in the t...
