Glass bead filled polyamide composite material and preparation method thereof

The invention discloses a glass bead filled polyamide composite material and a preparation method thereof, and belongs to the technical field of polyamide composite materials. Comprising 65-75 parts of polyamide resin, 15-28 parts of a filler, 7-12 parts of a macromolecular coupling agent, 2-10 parts of a dispersion stabilizer, 3-7 parts of a high-temperature-resistant agent, 3-5 parts of a coloring agent, 1-2 parts of a silane coupling agent, 5-10 parts of glass fibers, 10-15 parts of a surfactant and 0.5-1 part of a nucleating agent. By means of the added silane coupling agent, the plasticity of the composite material can be enhanced, then the plasticity of the glass beads is improved, the abrasion resistance of the glass beads is improved, the service life of the glass beads is prolonged, meanwhile, the silane coupling agent can improve the composite stability of the composite material, and the use effect is guaranteed. The materials are mixed, taken out and then subjected to melt granulation, the mixing c
