Plastic composite colorful kerb and preparation method thereof

The invention relates to a plastic composite colorful kerb and a preparation method thereof and belongs to the technical field of kerb preparation. The colorful kerb is prepared from waste high polymer material, coal ash, glass fiber, cross-linking agent and toner at mass ratio of (100-120):(300-400):(30-50):(40-60):(0-20). The preparation method comprises the following steps: plasticating the waste high polymer material to molten state on an opening type mixing mill; adding coal ash, glass fiber, cross-linking agent and toner in turn, uniformly mixing and then drawing slices; cooling the slices to semi-hard state at 50-60 DEG C and putting into a granulator for chopping into grains; extruding plasticating raw materials by putting the grains into a hopper of an extruding machine and then putting into a mould; using a hydraulic machine for pressurizing, cooling and then de-molding products, thereby acquiring the colorful kerb. The colorful kerb prepared according to the invention is colorful. Toner additives a
