Abstract: The butyl mixed rubber after processing in the ordinary way can not meet the airtightness
requirements of high-load tires.So the gear pump head is added to the original rubber filter to achieve both
high-pressure extrusion and fine filtration of rubber. In the same material of the tire rubber formula, the use
of self-developed dual-drive synchronous rubber gear pump rubber filtering machine for the airtight layer
of fine rubber filtration in order to study the performance of the rubber after filtration. By replacing different
screens, the degree of improvement in the performance of the rubber is investigated by the mesh size of the
screen. The performance of the rubber material filtered by the gear pump rubber filter machine has different
degrees of enhancement. In the 150 mesh, the performance has the largest increase，inculding 20.21%
increased of tear strength.It indicating that the filter mesh filtering rubber impurities at the same time can
also smooth the molecular chain.The higher the mesh, more smoother the molecular chain，meanwhile, the
higher the resistance to the rubber material during filtration.The resistance disappears after filtered, due to
the thermal movement and micro-configuration transformation, the molecular chain will be spontaneously
restored to the chaotic state, resulting in the mechanical properties of the rubber material will first rise and
then fall .The permeability coefficient is reduced by 78.11%, the symmetrical distribution of methyl groups in
nitrile, the molecular structure is symmetrical, which makes the aggregated state structure stacking closely.
