Problems solved by technology

[0003] When a longer length of transmission belt or endless belt is required, joints are required. Common joint methods include adhesive bonding and vulcanization. However, no matter which method is used for joints, there will be seams on the transmission belt. , this will not only increase the time-consuming and labor-intensive production process of the transmission belt, but also cause problems such as fracture of the transmission belt, low service life, and inability to meet the needs of high-speed, precise and stable transmission.

preparation example Construction

[0019] The preparation method of described rubber composition, comprises the following steps:

[0020] (1) Mastication: Put nitrile rubber, cis-butadiene rubber, chloroprene rubber, and non-stick roller synthetic rubber into the internal mixer for 1~3 minutes, and then put polyvinyl chloride into the internal mixer to continue mastication for 5~ 8 minutes, and then discharge the material in the internal mixer to the open mixer for 5~10 times, roll up and park after the wrapping roller is intact.

[0021] (2) Mixing: Add carbon black N220, dibutyl fat, engine oil, stearic acid, and the plastic glue prepared in step (1) to the internal mixer in sequence for 1~3 minutes, and then put them into the internal mixer in sequence Vaseline, coumarone, anti-aging agent, rosin, magnesium oxide, zinc oxide, paraffin, sulfur, vulcanizing agent DCP, and vulcanization accelerator are mixed for 0.5~2min, and then the materials in the internal mixer are discharged to a roller distance of 5mm to...

Embodiment 1

[0028] (1) Mastication: Put 5kg of nitrile rubber, 2kg of butadiene rubber, 1kg of neoprene, and 10kg of non-stick roller synthetic rubber into the mixer for 1min, then put 4kg of polyvinyl chloride into the mixer to continue plasticizing Refining for 5 minutes, then discharge the material in the internal mixer to the open mill and turn over for 5 times. After the wrapping roller is intact, roll it up and park it to obtain plasticized rubber;

[0029] (2) Mixing: Put 9.5kg of carbon black N220, 0.5kg of dibutyl fat, 0.1kg of engine oil, 0.1kg of stearic acid, and the plastic rubber prepared in step (1) into the internal mixer in sequence for 1min, and then 0.1kg of vaseline, 0.4kg of coumarone, 0.5kg of anti-aging agent, 0.5kg of rosin, 0.5kg of magnesium oxide, 2.1kg of zinc oxide, 0.3kg of paraffin, 0.3kg of sulfur, 0.1kg of vulcanizing agent, and vulcanization accelerator were put into the internal mixer in turn. Mix 0.1kg of agent for 0.5min, then discharge the material in...

Embodiment 2

[0031] (1) Mastication: Put 50kg of nitrile rubber, 25kg of butadiene rubber, 10kg of neoprene, and 140kg of non-stick synthetic rubber into the mixer for 3 minutes, and then put 50kg of polyvinyl chloride into the mixer to continue molding. Refining for 8 minutes, and then discharge the material in the internal mixer to the open mill for 10 times of refining. After the wrapping roller is intact, roll it up and park it to obtain plasticized rubber;

Abstract

The invention discloses a rubber composition and a preparation method and an application thereof. The rubber composition includes the raw materials in parts by weight: 5-50 parts of butadiene-acrylonitrile rubber, 2-25 parts of butadiene rubber, 1-10 parts of chloroprene rubber, 10-140 parts of non-sticky roller synthetic rubber, 4-50 parts of polyvinyl chloride, and 15-200 parts of an auxiliary material. The preparation method is the preparation method of the rubber composition. The application is the application of the rubber composition in a seamless transmission belt. The transmission belt prepared by the rubber composition has the advantages of abrasion resistance and high strength, is able to meet requirements of high-precision, high-speed, high-power, high-efficiency and long-life precise equipment on the transmission belt; the transmission belt has the advantages of one-time molding and no seams, also simplifies the technological process, improves the work efficiency, and also can meet the high-speed, precise and stable transmission demand.
