[0023] A preparation process of a polypropylene material, step 1, raw material preparation, consisting of the following raw materials in mass percentages, 60-75% of propylene raw material, 2-6% of epoxy soybean oil, 5-16% of powdered nitrile rubber, plasticized Agent DOS0.5-1%, plasticizer DOA0.5-1%, butadiene 6-9%, modifier 1-2%, stabilizer 1-4%, catalyst 1-2%;
[0024] Step 2, heating, sending the propylene raw material in the step 1 into a mixing agitator for heating, so that it changes from a gaseous state to a liquid state;
[0025] Step 3, blending and modifying, the powdered nitrile rubber raw material is sent into the mixing agitator and mixed with the propylene raw material after the gaseous state is changed into liquid state in the step 2, and the plasticizer DOS, the plasticizer DOA, and the ring are added in sequence. Oxygenated soybean oil, butadiene, modifier, stabilizer, catalyst, and then carry out esterification reaction and polymerization reaction in sequence...
