Surface modification and coating coloring method of Green PE material

The invention discloses a surface modification and coating coloring method of a Green PE material. The surface modification and coating coloring method comprises the following steps: step 1, selecting a Green PE raw material: using Green PE particles prepared from a sugarcane biomass raw material; a Green PE plastic part is prepared in an injection molding or extrusion mode, the YS1288 texturing standard is selected for the surface of a mold, the surface roughness Ra of the plastic part is controlled to reach 8-12 microns by adjusting technological parameters, and a uniform concave-convex microstructure is formed; 3, plasma surface treatment is conducted, specifically, the Green PE plastic part is put into plasma treatment equipment, the radio frequency power ranges from 100 W to 300 W, the electrode distance ranges from 10 mm to 30 mm, treatment gas is air or oxygen, and the treatment time ranges from 30 s to 120 s; 4, primer coating is conducted, specifically, within 30 minutes after plasma treatment, PP pr
