Step 2: prepare tealeaves fine powder, polyethylene, maleic anhydride grafted polyethylene, stearic acid, PE wax and the oxidation inhibitor after silane coupling agent treatment, tealeaves fine powder wherein after silane coupling agent process accounts for 30% ~ 35% of whole material gross weight, polyethylene accounts for 52% ~ 58% of whole material gross weight, maleic anhydride grafted polyethylene accounts for 8% ~ 10% of whole material gross weight, stearic acid accounts for 0.5% ~ 0.8% of whole material gross weight, PE wax accounts for 1% ~ 2% of whole material gross weight, and oxidation inhibitor accounts for 0.5% ~ 0.8% of whole material gross weight;
Step 3: the tealeaves fine powder after silane coupling agent process is added in high-speed mixer, open high-speed mixer, speed is 1000rpm, operates 5 ~ 15 minutes, makes the tealeaves fine powder temperature in high-speed mixer after silane coupling agent process reach 100 ~ 110 DEG C;
Step 4, shut down high-speed mixer, in high-speed mixer, add maleic anhydride grafted polyethylene, and open high-speed mixer, speed is 500rpm, operates 13 ~ 18 minutes;
Step 5, in high-speed mixer, add polyethylene, conversion high-speed mixing motor speed is 1000rpm, keeps 5 ~ 8 minutes;
Step 6, add stearic acid, PE wax and oxidation inhibitor successively, often add a kind of material and make high-speed mixing motor speed 1000rpm, operate 25 ~ 35 minutes, in high-speed mixer, obtain mixture;
Step 7, mixture adopt equidirectional parallel double-screw extruder extrude, in extrusion, four sections of temperature that the screw rod of equidirectional parallel double-screw extruder controls from front to back are respectively: 110 ~ 120 DEG C, 130 ~ 140 DEG C, 145 ~ 155 DEG C and 155 ~ 160 DEG C, head temperature 165 ~ 170 DEG C, screw rod revolution 40 ~ 50r/min; Extrude rear acquisition tealeaves composite polyolefine material.
3. the preparation method of tealeaves composite polyolefine material according to claim 2, is characterized in that: described tealeaves composite polyolefine material by air-cooled hot cut pellet and auto-filling, finally makes tealeaves composite polyolefine material particle successively.
4. the preparation method of tealeaves composite polyolefine material according to claim 2, is characterized in that: the molecular weight of described tealeaves composite polyolefine material is 40000 ~ 300000Dalton, elongation at break 245 ~ 315%, tensile strength 21 ~ 31Mpa.
