Embodiment Construction

[0008] The matrix material used in the experiment is QY8911-II type bismaleimide resin-glass fiber composite material, wherein the glass fiber used is KH550 type alkali-free chopped glass fiber (length is less than 2mm), in the composite material, resin and The weight ratio of glass fiber is: resin: glass fiber=7:3.

[0009] The metallization process of the composite material is carried out according to the above-mentioned process flow. The substrate first needs to be fully degreased and cleaned. The composition and process conditions of the degreasing liquid are: NaOH, 25g / L; NaCO 3 , 30g / L; Na 3 PO 4 , 25g / L; OP emulsion, 2g / L; the temperature is 50°C, and the time is 30 minutes. Then carry out pre-etching treatment at room temperature, that is, immerse the sample in 500g / L N-N dimethylformamide aqueous solution for 60 minutes; alcohol treatment is to wash the pre-etching treated sample with water and put it into a solution with a concentration of 500mL / L , in an ethanol...

Abstract

The metallization method of thermosetting resin bimaleimide resin-glass fibre composite material includes pretreatment of material surface and process of plating copper or plating nickel or plating gold or plating tin-lead alloy, and the described pretreatment includes the procedures of degreasing, cleaning, pre-etching, alcohol treatment, etching, activating, reducting and chemically-plating. The etching treatment is implemented by means of acid treatment, water washing, more acid treatment, water washing, nitrating, mixed alcali treatment and acid washing. Between metal cladding layer and base body they have good combined state.

Description

technical field [0001] The invention relates to a metallization method of a thermosetting resin bismaleimide resin-glass fiber composite material, which belongs to the surface metallization technology of non-metallic composite materials. Background technique [0002] Surface metallized resins or plastics are mainly used to replace metal materials, which can greatly reduce the weight of the overall system. Resins that have not been metallized are usually insulators, so they have high electrical resistance and have no shielding effect on electromagnetic radiation. Therefore, resin materials used in electronics, electric power and consumer electronic equipment often need to be plated with a metallized layer with good conductivity on the surface of the material. [0003] Improving the adhesion between the metallization coating and the resin substrate is one of the important technologies in the resin metallization process. After years of exploration,...
