Technical Field

Background

The extruded rubber sealing strip is easy to stretch and deform, the cutting precision is difficult to control during cutting, and the rapid assembly of the rubber strip is difficult to realize due to local deformation. Meanwhile, the rubber strip is radially compressed in a compressed state, and the axial direction of the rubber strip is not greatly influenced by the compression. By adding the chopped fibers with certain diameter and certain length-diameter ratio into the rubber, the extruded rubber strip can show different tensile properties in the axial direction and the radial direction. The chopped fiber has higher axial orientation degree, and the extruded rubber strip has larger tensile modulus when being stretched in the axial direction and small deformation, so that the rubber strip is not easy to stretch and deform in the axial direction, and the problem of cutting and assembling the rubber strip is solved. Therefore, an integrated device for orientation forming of the fiber-filled elastomer needs to be developed, and accurate and efficient implementation of fiber orientation and rubber forming is guaranteed.
