针对轮胎垫带在使用中常出现局部从轮辋气门嘴孔槽处挤出的缺陷，分析了垫带胶配方对这种质量缺陷的影响。认为较为实用的垫带胶配方为：ＳＭＲ２０１００；再生胶２００；硫黄５；促进剂１３；氧化锌４；硬脂酸２；防老剂３；炭黑７０；无机填料５５；软化剂２７。用这种配方试生产的垫带经实际使用，证明上述质量缺陷得到明显改善。若投入正常生产，按年产５０万条垫带（９００－２０规格）计，年降低成本达２１万元，经济效益可观。
Aiming at the defects that the tire pad is often squeezed out from the rim valve slot when it is used, the influence of pad adhesive formulation on the quality defect is analyzed. Considered more practical formula with pad rubber: SMR20100; Reclaimed rubber 200; Sulfur 5; Accelerator 1 3; Zinc oxide 4; Stearic acid 2; Antioxidant 3; Carbon black 70; Inorganic filler 55; The actual production of the pads tested with this formulation proves that the quality defects mentioned above have been significantly improved. If put into normal production, according to an annual output of 500,000 Strips (9 20-20 specifications) dollars, the annual cost down to 210,000 yuan, considerable economic benefits.
