摘　　要：本研究是将多种活化粉煤灰应用于橡胶制品中分别代替活性碳酸钙，轻质碳酸钙和中超炭黑作填料或补强剂。结果表明，良好的活化剂是获得优良活化灰的关键因素之一，粉煤灰的粒度和其表面性能是影响复合材料机械性能的主要因素。用良好的活化剂，采用干法研磨的活化方法可以兼顾这２个因素，获得较理想的活化灰，活化灰与有机物能很好地相容，加上它的球粒结构，因而有很好的加工性能。在橡胶制品中用活化灰全部代替活性碳酸钙，各项物理机械性能均合要求，半代轻质碳酸钙也是可行的，而用它代替中超炭黑作补强剂时，其代用量应在１／２以下。由于粉煤灰呈现灰色，因此不适用于浅色和鲜艳色的制品中。A study was carried out on the application of many kinds of activated pulverized coal ashes to replace activated calcium carbonate, light calcium carbonate or medium- super carbon black as fillers or reinforcers in rubber products. The results show that better activating agents are one of key factors to obtain the activated pulverized coal ashes of high quality,and the particle sizes and surface propertities of the coal ashes are the major factors affecting the mechanical performances of composite materials.The use of both better activators and dry grinding activation processes can incorporate the above factors to obtain more preferable activated coal ashes, allowing them to be well compatible with organic components, wich are coupled with its spheric particle structure to make it excellent in workability. The rubber products in which all calcium carbonate have been replaced with the activated coal ashes have all physical and mechanical properties meeting the requirements,those in which a half of light calcium carbonate have been replaced with the same are also practicable, and those in which less than 1/2 of medium-super carbon black have been replanced with the same can be useful.Due to its grey colour, the activated coal ashes are not suitable to be used in the products with a light or bright colour.
