Manufacturing method for producing tire regenerated rubber by plasticizing through normal-pressure continuous plasticator

Abstract

The invention discloses a manufacturing method for producing tire regenerated rubber by plasticizing with a normal-pressure continuous plasticator, which comprises the following steps: A, extruding and flattening raw materials by using a magnetic suction roller, absorbing metal materials in impurities, shearing the raw materials by using a shearing device, stirring in a stirrer, and selecting rubber powder particles of 5-10 meshes by using a screen; b, adding a mixture of the rubber powder particles without the metal materials, a plasticizer and water into a double-screw plasticator, and heating a front machine barrel of the double-screw plasticator through a heating device outside the double-screw plasticator; the technical problems that the temperature cannot be controlled and the pressure is too high in the current rubber production process can be effectively solved, the situation that carbon-carbon bonds are broken in the vulcanization process is avoided, sufficient temperature can be guaranteed for vulcanization, uniform rubber particles are adopted for vulcanization, the technical problem that the rubber particles are different in time in the vulcanization process is solved, and the production efficiency is improved. The mechanical property of the manufactured rubber is improved.

Description

technical field [0001] The invention relates to the technical field of rubber production, in particular to a method for producing tire regenerated rubber by plasticizing with an atmospheric continuous plasticizer. Background technique [0002] Because the plasticizing machine needs heat energy to vulcanize during the plasticizing process, but friction between the screw and the rubber powder is likely to occur, which will cause the temperature to be too high, and too high temperature will cause the carbon-carbon bond to be interrupted, resulting in The rubber powder is over-vulcanized during the plasticizing process, resulting in damage to the strength of the rubber material, and the rubber powder before vulcanization is not uniform enough, so that the gap is too large during the vulcanization process of the plasticizing machine, causing the rubber powder to fail to pass through in the same time The runner affects the mechanical properties of the vulcanized rubber, and the pr...
