Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a nano-silicon nitride powder filler wear-resistant polyethylene plastic and a preparation method thereof. Background technique [0002] We know that since the 1980s, a new field of science and technology - nanoscience and nanotechnology was born and flourished. So far, nanotechnology has penetrated into materials, electronics, chemistry, biology and other fields, especially in the application of materials. Nanoplastic is a high-tech new material, which is an organic / inorganic nanocomposite material formed by dispersing inorganic fillers in an organic polymer matrix at a nanometer size. The chemical properties of polyethylene plastic are stable, but the strength is low, easy to deform, not heat-resistant, and easy to burn, which limits the application of polyethylene. The use of nanotechnology to modify polyethylene plastic can improve the performance of polyethylene and expand...
