Problems solved by technology

However, on the one hand, because these metal copper compounds are prone to decomposition during processing, the resulting elemental copper is enriched on the surface of the product, which seriously affects the effect of electroless electroless plating; Thermal Oxidative Aging (Degradation and Stabilization of Polymer, Applied Science and Publishers LTD London, 1975, 90-92)
In the above composite material formula, there is direct contact between the metal copper element and the polymer substrate, so that the polymer substrate is prone to thermal oxygen aging reaction under the catalysis of the copper compound, which affects the service life of the product

Abstract

The invention belongs to the field of laser direct structuring composite materials and discloses a laser direct structuring PC/ABS composite material with an excellent thermo-oxidative aging resistance, as well as a preparation method and application thereof. The composite material comprises the following components in percentage by weight: 60-80% of a PC/ABS base material, 5-15% of a halogen-free flame retardant, 5-15% of laser activated particles, 0-10% of heat conductive inorganic filler and 0-5% of other additives. The preparation method of the laser activated particles comprises the following steps: dropwise adding an alcohol solution of nano copper powder, an imitator and a silane coupling agent into a positive microemulsion consisting of acrylate monomer, dodecyltrimethylammonium bromide and water; and heating for reaction, filtering and drying to obtain the laser activated particles. Metal copper is modified by a micro-emulsion polymerization method to obtain the laser direct structuring PC/ABS composite material which has good laser-induced electroplating performance and excellent thermo-oxidative aging resistance.
