(2) mixing: the MPU plasticated is put in banbury, add stearic acid, stearyl ester zinc and high wear-resistant carbon black, mixing 10 minutes, control its temperature less than 100 DEG C；
(3) slice: the material mixed slice on film-discharging machine, sheet thickness 6mm, hangs, cools down, to park 24h stand-by；
(4) add sulfur: the sheet material after parking is placed in mill, roll spacing 3-4mm, add cumyl peroxide and Triallyl isocyanurate after bag roller, after mix homogeneously, make a call to 3 triangle bags, thin logical 2 times, temperature controls below 100 DEG C, slice cooling；
(5) carrying out product sulfuration, vulcanization parameters controls as follows: board temperature 170 DEG C, cure time 500 seconds, board pressure 15-20MPa.
Described MPU materials application is in self arrangement penknife.
The remarkable advantage of the present invention is: the Akron abrasion of the MPU material of the present invention is less than 0.1cm3, be applied to self arrangement penknife, building rubber compound wheel uses through long-time, with plastics rotating disk fretting wear compared with light, residue powder is less, abrasion loss is less.
