Special high quality kpo clamp rail fastening system, extrusion resistance, no deformation, slow aging time. The composition of rubber cushion rubber composite material under railway pillow rail comprises 100 parts of matrix compound, 1 ~ 5 parts of accelerator, 1 ~ 3 parts of antioxidant, 2 ~ 10 parts of nanometer zinc oxide powder, 0.2 ~ 1.5 parts of vulcan agent, 30 ~ 60 parts of carbon black, 30 ~ 60 parts of inorganic filler, 0.5 ~ 10 parts of four needle-like zinc oxide whisker, and 0.2 ~ 5 parts of coupling agent. The matrix compound is composed of natural rubber, styrene butadiene rubber and butadiene rubber. The static steel value of the underrail rubber pad prepared by the material is 50 ~ 70MN/m, the tensile strength is increased by 10 ~ 30%, the strength decline value after aging is reduced by 15 ~ 40%, the wear resistance is increased by 15 ~ 50%, the vibration attenuation coefficient is increased by 20 ~ 50%, and the noise reduction effect is increased by 5 ~ 20%. Mainly used for high-speed railway, high-speed railway and ordinary railway vibration reduction under the rail rubber plate, its components include matrix rubber, accelerator, antioxidant, vulcan agent, carbon black, inorganic filler, coupling agent and four needle-like zinc oxide whisker, its characteristics are that the components also contain nano zinc oxide powder, with the proportion according to weight. Matrix compound 100 parts, accelerator 1 ~ 5 parts, antioxidant 1 ~ 3 parts, nano zinc oxide powder 2 ~ 10 parts, vulcanization agent 0.2 ~ 1.5 parts, carbon black 30 ~ 60 parts, inorganic filler 30 ~ 60 parts, four needle-like zinc oxide whisker 0.5 ~ 10 parts, and coupling agent 0.2
