Method for surface metallization of resin-based composite material compressed by mold

Abstract

The invention discloses a method for surface metallization of a resin-based composite material compressed by a mold. The resin-based composite material compressed by a mold comprises one or more thermosetting resins, one or more fibers and one or more filling materials. The method provided by the invention can realize surface metallization of the resin-based composite material compressed by a mold. The key point of surface metallization is effectiveness in resin-based composite material roughening. Through the technical measures which comprise utilization of supersonic waves in roughening andimprovement of a roughening solution and realize good effects of roughening the one or more fibers and the one or more filling materials in the resin-based composite material by the roughening solution, the method realizes the surface metallization of the resin-based composite material compressed by a mold. The method is suitable for surface metallization of the resin-based composite material compressed by a mold, and has high efficiency, environmentally friendly characteristics and good metalized layer adhesion.

Description

technical field [0001] The invention relates to a preparation method for surface metallization of a resin-based composite material which can be molded, and belongs to the class of chemical plating methods for surface metallization of non-metallic materials. Background technique [0002] Products with good electrical conductivity on the surface are often required in industry, such as selective light-transmitting devices, electromagnetic reflection devices, communication equipment, and medical equipment. These products realize their functions through the good electrical conductivity of their surfaces. The use of articles with good electrical conductivity on the surface is so widespread that the manufacture of such articles has become a hot topic. [0003] Metals with good electrical conductivity are usually noble metals (such as gold and silver, etc.) or non-ferrous metals (such as aluminum and copper), which are expensive, so such products with good electrical conductivity on...

[0016] Chinese invention patent application CN201010297892.8 discloses a method for preparing metallized coatings on the surface of epoxy resin-based composite materials. Although this method has a good effect on the surface metallization of epoxy resin-based composite materials, there are still Certain problems, the existing problem is that the coarsening process still adopts the chromic anhydride-concentrated sulfuric acid system. As mentioned above, chromium ions are one of the harmful heavy ion metals that cause environmental pollution and endanger human health. At the same time, the epoxy resin-based composite material is a non-molding molding material, and its composition is relatively simple compared with the resin-based composite material that can be molded. The method disclosed in CN201010297892.8 is not applicable. Metallization of Compression Molded Resin Matrix Composites

[0017] Chinese invention patent ZL200710150743.7 discloses a new surface metallization method for carbon fiber reinforced epoxy resin-based composite materials. Compared with the standard process of surface metallization of resin-based composite materials, it is directly sensitized after degreasing, and then electroless plating , this surface metallization method has a good effect on specific epoxy resin-based composites with a carbon fiber content of more than 30%, but it cannot be generally used for resin-based composites, especially for those containing a large amount of structural fillers.
