改性粉煤灰对橡胶补强作用的研究

Research on the Straightening Effect on Rubber by PropertyConverted Flyash

对粉煤灰进行分级处理，将小于４５μｍ的粉煤灰经表面改性处理后作为橡胶的补强填充剂。对其作用机理和混炼胶料的加工性能进行试验研究的结果表明，改性粉煤灰的增量补强作用主要取决于它的粒度、形状、表面结构和性质等。其主要技术指标与半补强炭黑相当。

Flyash was classified and the minus 45 micron fraction was converted on its surface property and then used as a strengthening filler for rubber. Research on the mechanism and experiments on kneadingmixing of rubber feed material denoted that the strengthening effect of converted flyash depended upon its particle size, particle shape, surface structure and characteristics. Its main quality indexes match those of semistrengthening carbonblack and it can replace partially or completely carbonblack as filler for conventional rubber.
