Abstract

The invention discloses a high-density polyethylene-based impact-resistant composite material and a preparation method thereof. The composite material is prepared from the following components in percentage by weight through melt blending in high polymer blending equipment: 60-95% of high-density polyethylene, and 5-40% of modified silicon shear thickening gel, wherein the modified silicon shear thickening gel is prepared from the following components in percentage by weight through blending in high polymer blending equipment: 70-95% of silicon shear thickening gel and 5-30% of silicon dioxide particle; and the particle size of the silicon dioxide particle is 50-200 nanometers. Compared with other high-density polyethylene materials, the high-density polyethylene-based impact-resistant composite material obtained by the invention has better impact resistance and processability.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and relates to a high-density polyethylene-based high-impact-resistant material and a preparation method of the material. Background technique [0002] Shear thickening refers to the phenomenon that the viscosity of the system increases rapidly, violently and nonlinearly when it is subjected to shear force. The main principle is that when a certain material is not subjected to shear or impact force, the dispersed phase particles and the dispersion medium form a network structure due to the hydrogen bond, and the dispersed phase particles do not interfere with each other. When the force acts, the originally formed network structure gradually disintegrates, and the dispersed phase particles collide with each other to form particle clusters, which reduces the fluidity of the material, resulting in a sharp increase in its viscosity, showing a "thickening" phenomenon. When the sh...
