Connection agent, zinc, acetate fiber, Isonicotinic acid, manganese stearate add in ethanol together, stir 30-at 60-80 DEG C
60min, filters and lyophilization, obtains property-modifying additive；
S3, the pretreatment waste old by step S1, CSM, propylene-ethylene semi-crystalline co-polymers, ethylene
Base bis-stearamides, amido diisopropyl disulfide for phosphoric acid tungsten and phthalic acid two (2-ethyl hexyl) ester at 75-95 DEG C
Once stirring mixing 0.5-2h, is subsequently adding oleamide, N-Phenyl beta naphthylamine, phosphoric acid propane diamine, at 45-65 DEG C second
Secondary stirring mixing 30-65min, obtains rubber mixture；
S4, by above-mentioned property-modifying additive and rubber mixture mix homogeneously at 60-75 DEG C, be subsequently adding remaining raw material and mix
Uniformly, it is transferred in double screw extruder, extrudes under the conditions of 180-250 DEG C of temperature, the screw speed of 20-50rpm, to obtain final product.
The preparation method of high abrasion anti tear reclaimed rubber material the most according to claim 4, it is characterised in that described step
In rapid S1 under 240W ultrasonic power ultrasonic 50min；Described step S1 is reacted at 140 DEG C 35min.
The preparation method of high abrasion anti tear reclaimed rubber material the most according to claim 4, it is characterised in that described step
After rapid S2 calcines 1.5 hours at 450 DEG C finely ground to 150 mesh；Described step S2 stirs at 78 DEG C 55min.
The preparation method of high abrasion anti tear reclaimed rubber material the most according to claim 4, it is characterised in that described step
In rapid S3, at 88 DEG C, stirring for the first time mixes 1.5h；In described step S3, at 50 DEG C, second time stirring mixes 45min.
The preparation method of high abrasion anti tear reclaimed rubber material the most according to claim 4, it is characterised in that described step
In rapid S4 at 72 DEG C mix homogeneously；Described step S4 is extruded under the conditions of 195-248 DEG C of temperature, the screw speed of 25rpm.
