Abstract

The invention discloses a transmission belt material. A formula of the material comprises the following components in parts by mass: 10 to 25 parts of natural rubber, 25 to 40 parts of styrene butadiene rubber, 60 to 75 parts of nitrile rubber, 1 to 4 parts of sulfur, 5 to 8 parts of plasticizer, 2 to 5 parts of bonding agent, 7 to 11 parts of zinc oxide, 2 to 4 parts of anti-aging agent RD, 1.5 to 3 parts of anti-aging agent NBC, 0.5 to 2 parts of anti-aging agent DNP, 15 to 18 parts of carbon black, 5 to 6 parts of white carbon black, 1 to 3 parts of N-cyclohexyl-2-benzothiazolesulfenamide, 1 to 2 parts of 2,2'-dibenzothiazyl disulfide, 3 to 5 parts of stearic acid, 10 to 11 parts of coumatone resin, and 3.5 to 5 parts of pine tar. A preparation method comprises the following steps: (1), putting the natural rubber, the styrene butadiene rubber and the nitrile rubber into a banbury mixer, heating to the temperature of 110 to 120 DEG C; (2), adding half of the carbon black and rising the temperature to be 145 to 155 DEG C for milling for 4 to 6min, sequentially adding the zinc oxide, the white carbon black, the coumatone resin, an accelerator and the anti-aging agents for milling; (3), adding the rest carbon black, the plasticizer, the sulfur and the pine tar into a open mill for carrying out milling for 6 to 9min to obtain masterbatch; (4), putting the masterbatch into a vulcanizing mold for carrying out vulcanization treatment.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a transmission belt material and a preparation method thereof. Background technique [0002] The essence of the transmission belt is a connection belt that transmits the power source to the equipment by means of the connection of the mechanical structure, so that the equipment can run. Because the transmission belt has the excellent performance of free variable speed, low price and convenient replacement, it plays an important role in today's mechanical transmission parts, so the quality of the transmission belt material will directly affect the operation of mechanical equipment and the quality of its production parts. With the rapid development of the contemporary machinery industry, especially some new agricultural machinery, automobile and other industries, the requirements for the performance of transmission belt materials are becoming more and more strin...
