Glycol ether 0.5-1.5
N cyclohexyl 2 benzothiazole sulfenamide 0.5-1.5
Dibenzothiazyl disulfide 0.5-1.0
Sulphur 1-3
Method for preparing rubber of the present invention is identical with existing preparation method.
Compared with prior art, the present invention is owing to adding antioxidant, and antioxidant property is good; Owing to adding toughner, intensity is high.The present invention is applicable in dredge rubber pipe outer covering layer.
