Abstract

The invention discloses a preparation method of an annular flexing resistant synchronous belt. The synchronous belt comprises the following raw materials by mass percentage: 4% of MOCA (4,4'-methylenebis(2-chloroaniline)), 1% of releasing agent, 5% of lubricant, 12% of chain extender, 8% of plasticizer, 5% of steel wire rope, 3% of glass cord, 2% of aramid fiber, 40% of polyhydric alcohol and 20%of polyisocyanate, wherein polyisocyanate is one of diphenylmethane diisocyanate, 2,4-toluene diisocynate, 2,6-toluene diisocynate, toluidine diisocyanate, xylidine diisocyanate, 1,5-naphthalene diisocyanate, polymethylene polybenzene isocyanate, isophorone diisocyanate, hexamethylene diisocyanate, dicyclohexyl methane diisocyanate and p-phenylene diisocyanate. The method obviously improves wearresistance, tension resistance and flexing resistance of the synchronous belt, and the whole synchronous belt has better properties.

Description

technical field [0001] The invention relates to the technical field of synchronous belts, in particular to a preparation method of an endless tortuous-resistant synchronous belt. Background technique [0002] The synchronous belt is an endless belt with steel wire rope or glass fiber as the strength layer and covered with polyurethane or neoprene rubber. The inner circumference of the belt is toothed to mesh with the toothed pulley. When the synchronous belt is driven, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, the oil resistance is good, the wear resistance is good, and the anti-aging performance is good. The general operating temperature is -20°C-80°C, v<50m / s, P<300kw, i<10, it can also be used for low-speed transmission for synchronous transmission. [0003] The main problems of the synchronous belt are the fatigue fracture of the belt body; the shearing and crushing of the belt teeth; The belt body is broken...
