Two, according in above-mentioned formula B, industrial cloth taking-up placement is standby, all the other compositions are placed in Mixing roll mixing to opening the rear discharging of refining, be controlled at 64～66 degrees centigrade in temperature and discharging embrocated on the tow sides of industrial cloth, then according to the size fabric dividing;
Three, the slow film after the classification cutting and industrial cloth in above-mentioned steps one and step 2 are positioned over the synthetic moulding of shaping die together, are the driving belt crude green body;
Four, sulfuration, it is to vulcanize 25～35 minutes in the vulcanization plant of 140～160 degrees centigrade that the driving belt crude green body is positioned over temperature, realizes the sulfuration setting;
Five, the driving belt that takes out after sulfuration formalizes is the driving belt finished product after checking.
10. the making method of driving belt according to claim 9, it is characterized in that: described vulcanization plant includes sulfurizing pot (1), open-topped curing bag (2), described curing bag (2) is placed in sulfurizing pot inner chamber (11), described sulfurizing pot inner chamber (11) is connected with vapor source by the first steam pipe (5), described curing bag inner chamber (21) bottom is connected with vapor source by the second steam pipe (4), during sulfuration, described driving belt crude green body is positioned over the driving belt crude green body in curing bag (2) by curing bag (2) open top, then the open top at curing bag (2) covers cover plate (3), described cover plate (3) closes the open top of curing bag (2), then described the first steam pipe (5) is passed into the steam that pressure is 0.7Mpa, make sulfurizing pot inner chamber (11) pressure remain on 0.7Mpa, and pass into the steam that pressure is 0.4Mpa in the second steam pipe (4), make curing bag inner chamber (21) pressure remain 0.4Mpa, sulfuration insulation 25～35 minutes, namely complete vulcanisation step.
