Color rubber synchronous belt and preparation method thereof

Abstract

The invention relates to a color rubber synchronous belt and a preparation method thereof. The synchronous belt comprises a synchronous belt skeleton and a rubber sheet attached to the outer surface of the synchronous belt in a wrapping manner, wherein the raw material of the rubber sheet comprises the following components in parts by weight: 20 to 40 parts of saturated Buna-N rubber, 30 to 50 parts of thiol chloroprene rubber, 20 to 40 parts of chlorinated butadiene styrene rubber, 4 to 8 parts of methacrylic acyloxy silane, 30 to 50 parts of reinforced resin, 5 to 6 parts of cross-linking agent, 2 to 6 parts of burnishing master batch, 0.5 to 1.5 parts of curing agent, 8 to 12 parts of plasticizer, 1 to 3 parts of anti-aging agent, 3 to 7 parts of telechelic polymer and 5 to 7 parts of homogeneous agent. Through adding various colors of burnishing master batch, the color of the synchronous belt is different from the black color in the past, and is more bright and eye-catching, and better wear-resisting and heat-resisting performances are realized.

Description

technical field [0001] The invention relates to the technical field of synchronous belts, in particular to a colored rubber synchronous belt. Background technique [0002] The large-load and high-speed synchronous belts currently used in the market are all black. During operation, friction with the pulley will produce a small amount of black rubber powder, which is likely to cause slight pollution to the environment. Therefore, papermaking, The prevention and printing and dyeing industries are in urgent need of a rubber synchronous belt that does not pollute the environment. The synchronous belt that people require should not be bright in color, avoid polluting the environment, and need to have the high strength that the black rubber synchronous belt under the prior art has. , so as to replace the existing black rubber timing belt. Contents of the invention [0003] A technical problem to be solved by the present invention is to provide a color timing belt with high stren...
