Abstract: This article studies the modification of waste special HNBR recycled rubber with trans polyoctene
(TOR) and its application in the inner layer of oil resistant rubber pipes for vehicles. The results showed that
the performance of the inner layer rubber with TOR modified special recycled rubber was superior to that
without modified special recycled rubber. With the increase of the dosage of TOR modified special recycled
rubber, the hardness, tensile strength, elongation, and tear strength of the rubber material show a downward
trend, while the compression permanent deformation shows an upward trend. After aging, the hardness
and tensile strength of the rubber material are greater than before aging, and the elongation is lower than
before aging. After high temperature and oil resistance, the hardness, tensile strength, and elongation of the
rubber material all decrease. When the dosage of TOR modified special recycled rubber is 12 parts, the cost-
effectiveness of the rubber material is the highest, with hardness, tensile strength, elongation, tear strength,
and compression set of 72, 16.13MPa, 39.32kN/m, 283%, and 39.5%, respectively. The change rates of tensile
strength and elongation after aging are +5.7% and -13.1%, respectively. The change rates of tensile strength
and elongation after oil resistance are -8.3% and -19.2%, respectively.
