Abstract

The invention relates to the technical field of synchronous belts, and discloses an EPDM (Ethylene-Propylene-Diene Monomer) rubber synchronous belt and a preparation method thereof. (B) preparing belt-shaped rubber; (C) forming a synchronous belt; and (D) vulcanizing to obtain the EPDM rubber synchronous belt. EPDM rubber materials of two specifications are selected in the stage of the step (B), mixing is carried out in batches, strip-shaped rubber is obtained, the high ethylene ratio is achieved, and meanwhile the good rolling performance is achieved; according to the present invention, the prepared EPDM rubber synchronous belt has characteristics of high molecular weight and good compatibility with the filler, such that the prepared EPDM rubber synchronous belt has advantages of excellent temperature resistance, working temperature range of-40 DEG C to 120 DEG C, and adaptability to harsh application environments.

Description

A kind of EPDM rubber timing belt and preparation method thereof technical field The present invention relates to the technical field of synchronous belts, in particular to a kind of EPDM rubber synchronous belt and preparation method thereof. Background technique [0002] The industrial rubber synchronous belt is made of glass fiber as a strength layer, covered with an annular belt of CR rubber, and the inner circumference of the belt is made of Toothed so that it meshes 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, oil-resistant, oil-resistant Good abrasiveness and anti-aging performance, the general use temperature is ‑30℃~100℃. With the development of my country's industry, some special In special industries, the synchronous belt needs to work in harsh application environments of cold or high temperature, and cannot fail in the working environment. debri...
