内胎配方中新材料的应用

Application of Less Expensive Reinforcing Materials to Tube Compound

对活性硅白、活性陶土Ｍ－２１２在轮胎内胎中的应用进行了研究。结果表明，胶料物理性能与原配方相当，但分散性好，能改善胶料的加工性能和制品的综合性能，其中活性陶土Ｍ－２１２还能部分替代半补强炭黑，可以降低胶料成本０．４７元·ｋｇ－１。

A study was made on the application of activated Guibai (an inorganic short fibre) and activated clay M 212 to the tube compound The results showed that the physical properties of the test compounds were similar to those of the existing compound while the dispersion and processibility of the compound as well as the performance of the finished product improved The cost of compound decreased by 0 47 Yuan·kg -1 when the semi reinforcing carbon black was partly replaced by activated clay M 212
