摘　　要：通过增大NR/SBR并用比、减小再生胶和填充剂用量优化载重斜交轮胎内衬层配方,提高胶料的300%定伸应力、拉伸强度和撕裂强度;胎体第1帘布层挂胶由2次减为1次,并增大内衬层的厚度,既有效解决了成品轮胎胎里露线问题,又降低了生产成本。The inner liner formula of bias truck tire was optimized by increasing the NR proportion in NR/SBRblend and decreasing the addition levels of reclaimed rubber and filler to improve the modulus at 300 %, tensile strength and tear strength of vulcanizate; and the exposed cord in the cavity of finished tire was eliminated and the production cost reduced by coating the 1^# cord ply one time rather than two times and increasing the gauge of inner liner.
