Bio-based itaconate rubber sizing material and rubber synchronous belt

The invention relates to the technical field of rubber, and discloses a bio-based itaconate rubber sizing material and a rubber synchronous belt, the bio-based itaconate rubber sizing material comprises the following raw materials by weight: 100 parts of bio-based itaconate rubber, 5-10 parts of zinc methacrylate, 50-70 parts of carbon black N550 and 2-4 parts of a peroxide vulcanizing agent. According to the bio-based itaconate rubber material, the zinc methacrylate and the peroxide vulcanizing agent are used for synergistically improving the hardness, the carbon black N550 is used for improving the strength of the rubber material, the heat generation of the rubber material is reduced, the flowability is improved, and the scorching time is prolonged, so that the tooth filling performance of the rubber material is improved, the back breakage of a product is reduced, and the yield is improved; the rubber material can be processed for multiple times, rubber material flashes in the processing process can be recy
