The invention relates to the technical field of tire rubber, in particular to a tread rubber composition for a smooth tire of a road roller and the tire. The rubber material is characterized by being prepared by mixing the following components in parts by weight: 50-60 parts of natural rubber, 35-45 parts of butadiene-acrylonitrile rubber, 5-10 parts of chloroprene rubber adhesive, 4-5 parts of zinc oxide, 2-3 parts of stearic acid, 3-5 parts of DOP, 5-8 parts of RAE oil, 45-55 parts of carbon black, 5-10 parts of white carbon black, 3-4 parts of hydrocarbon resin mixture 40MSF, 1-2 parts of tear-resistant resin TYC0500, 0.5-1.5 parts of anti-aging agent RD, 1.5-2.0 parts of anti-aging agent 4020, 0.5-1.0 part of anti-aging agent DTPD, 1.5-2.5 parts of protective wax, 1.0-1.5 parts of sulfur, 1.0-1.6 parts of accelerant and 0.2 part of scorch retarder CTP. The high temperature resistance and oil resistance of the smooth tire tread rubber can be remarkably improved, the tensile strength, stress at definite elongation, hardness, abrasion and other mechanical properties and swelling degree of the tread rubber are guaranteed, the performance requirements of long-time asphalt contact operation are met, rapid abrasion of the tread rubber is effectively avoided, and the service life of the tire is prolonged.

    本发明涉及轮胎橡胶技术领域,具体地说是一种用于压路机光面轮胎的胎面胶橡胶组合物和轮胎。包含以下的组分按重量份数混炼构成:天然橡胶50~60,丁腈胶35~45,氯丁胶5~10,氧化锌4~5,硬脂酸2~3,DOP 3~5,RAE油5~8份,炭黑45~55,白炭黑5~10,烃类树脂混合物40MSF 3~4,抗撕裂树脂TYC0500 1~2,防老剂RD 0.5~1.5,防老剂4020 1.5~2.0,防老剂DTPD 0.5~1.0,防护蜡1.5~2.5,硫磺1.0~1.5,促进剂1.0~1.6,防焦剂CTP0.2。本发明可显著提高光面轮胎胎面胶的耐高温、耐油性能,保证胎面胶拉伸强度、定伸应力、硬度、磨耗等力学性能及溶胀程度,满足在长时间接触沥青作业的性能要求,有效避免了胎面胶快速磨损,提高了轮胎的使用寿命。
