Description

technical field [0001] The invention relates to the technical field of vulcanization bladder production equipment, in particular to a premixing device for producing vulcanization bladders. Background technique [0002] The vulcanizing bladder is a hollow thin-walled rubber product of the tire vulcanizing machine. It is used to fill the inner cavity of the green tire to be vulcanized and then pass it into the heating medium, and cooperate with the vulcanizing machine to carry out shaping and vulcanization operations; the quality of the vulcanizing bladder directly affects the cost and cost of tire manufacturing. Quality: There are many raw materials for the production of tire curing bladders, including butyl rubber, zinc oxide, carbon nanotubes, stearic acid, resin, carbon black, castor oil, stannous chloride, etc., including powder and liquid, powder The particle size of the material is different, the viscosity and solubility of the liquid are different, and the uniformity o...
