Embodiment 1

[0038] A pretreatment process before electroless plating on the surface of a polyether ether ketone composite material, comprising the following steps:

[0039]Step 1. Stress relief: wash the surface of the finished polyether ether ketone composite material with ethanol for at least 2 times, then put it in an oven at a temperature of 40-80°C and dry it for 2-10 hours. After drying, polyether is obtained Etherketone composite parts are ready for use;

[0040] Step 2. Degreasing: put the polyetheretherketone composite material part in step 1 into the dewaxed water at a temperature of 50-80 °C for ultrasonic cleaning for 5-30 minutes, and obtain the degreased polyether ether ketone composite material part for use;

[0041] Step 3. Pretreatment: Wash the polyether ether ketone composite material parts degreased in step 2 with water for at least 2 times, then soak them in the pretreatment solution at a temperature of 20-30°C for at least 5 minutes, take them out and wash them with ...

Abstract

The invention belongs to the technical field of surface modification and electroplating of special materials, and particularly relates to a polyether-ether-ketone composite material surface chemical plating pre-treatment technology. The polyether-ether-ketone composite material surface chemical plating pre-treatment technology comprises the following steps of stress removal, oil removal, pretreatment, etching, adjustment activation and peptizing chemical plating. The polyether-ether-ketone composite material surface chemical plating pre-treatment technology solves the problems of the low bonding strength and the low product qualification rate in the prior art; and a metal plating layer obtained after the chemical plating pre-treatment technology is high in bonding strength, is not prone tofalling off, is high in product qualification rate and is suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of surface modification and electroplating of special materials, and in particular relates to a pretreatment process before electroless plating on the surface of a polyetheretherketone composite material. Background technique [0002] Plastics are common items in everyday life. Now the market is common to have decorative metal layers on some plastic surfaces, which are bright and smooth. The surface metallization of these plastics is generally processed by physical vapor deposition techniques or chemical deposition techniques. However, physical vapor deposition technology is difficult to metallize the surface of heterogeneous parts. [0003] Electroplating is mainly for electrical conductors, which consumes more energy. The electroless plating process is simple and the production process is convenient, but pretreatment between plastic polymers is required to activate the surface. For example: the general...
