Abstract

The invention discloses a sizing material for producing a high-strength synchronous belt. The sizing material for producing the high-strength synchronous belt is prepared from, by weight, 37.89%-42.64% of chloroprene rubber, 14.87%-18.67% of butadiene styrene rubber, 8.14%-12.48% of high styrene rubber, 1.23%-4.35% of zinc oxide, 1.14%-3.15% of magnesium oxide, 0.26%-0.67% of stearic acid, 0.25%-0.75% of an anti-aging agent 4010 NA, 1.98%-4.87% of 1-dodecanethiol, 0.67%-1.95% of an anti-aging agent ODA, 0.24%-0.65% of antiozonant, 21.68%-26.89% of carbon black N762 and 0.14%-0.37% of accelerant. According to the sizing material for producing the high-strength synchronous belt, by synchronously using the chloroprene rubber, the butadiene styrene rubber, the high styrene rubber, stearic acid, the anti-aging agents, 1-dodecanethiol, the antiozonant, the carbon black N762 and the accelerant, the properties of the raw materials complement each other, so that the cost of the sizing materialis reduced; by adding the butadiene styrene rubber and the high styrene rubber, the toughness and the strength are improved; by adding the anti-aging agents and the antiozonant, the anti-aging performance is improved, and the service life of the synchronous belt is improved.

Description

technical field [0001] The invention belongs to the technical field of synchronous belt processing and manufacturing, and in particular relates to a rubber material for producing high-strength synchronous belts. Background technique [0002] The synchronous belt is a sealed endless belt with equally spaced teeth on the inner peripheral surface. When rotating, the power is transmitted through the meshing of the belt teeth and the gear teeth. The synchronous belt combines the advantages of belt drive, chain drive and gear drive, and has many advantages such as high transmission efficiency, accurate transmission ratio, large transmission ratio range, stable transmission, small force on the shaft, low noise, and energy saving. [0003] The timing belt is mainly composed of three parts: the timing belt film, the timing belt skeleton and the timing belt cloth layer. At present, there are two kinds of products in the production of automobile synchronous belts at home and abroad, o...
