Problems solved by technology

[0003] However, in actual use, polypropylene spray-free materials also face many challenges. First, the metallic toner is directly added to the resin, which has poor compatibility with the resin matrix, so that the ideal color and high metallicity cannot be obtained. Texture; Second, the resin matrix itself has poor scratch resistance, which makes the spray-free material prone to scratches
For example, high-gloss spray-free materials for small household appliances will inevitably be touched and squeezed during transportation. Wiping the surface dust during use may cause scratches on the appearance, and the appearance of scratches will greatly reduce consumption. The user experience will also reduce the actual service life of related materials

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a polypropylene / polyamide / polyketone composite material and a preparation method thereof. Background technique [0002] In recent years, with the development of spray-free materials, more and more parts have begun to adopt spray-free technology from the original painting and oil spraying. Spray-free technology usually adds metallic color powder to the matrix resin so that the obtained non-spray material presents a metallic texture. Spray-free technology can not only save process steps and reduce costs, but also be environmentally friendly. [0003] However, in actual use, polypropylene spray-free materials also face many challenges. First, the metallic toner is directly added to the resin, which has poor compatibility with the resin matrix, so that the ideal color and high metallicity cannot be obtained. Texture; Second, the resin matrix itself has poor scratch resistance, ...
