Embodiment Construction
[0013] 1. Granulation
[0014] Crush the natural straw to 100-150 mesh and set aside.
[0015] Crush the cork powder to 600-800 mesh and set aside.
[0016] The crushed natural straw, cork powder, polypropylene and titanate coupling agent, stearic acid, ethylene bisstearic acid amide, and titanium dioxide account for 8-20% and 8-12% of the total mass of raw materials, respectively. , 64~70%, 0.3~0.5%, 0.7~1%, 2.5~3%, 0.5~1% are mixed evenly, and placed in a twin-screw mixing extruder after high temperature dehydration, at 150~165 Extrusion and granulation under the condition of ℃, the raw material particles of the present invention are obtained, and the density is 900~930 kg / m after testing 3 .
[0017] 2. Application
[0018] The plastic particles of the present invention can replace general polypropylene for production. The present invention can be placed in an injection molding machine, and the injection molding temperature is selected to be 170-180°C, and different pr...
