摘要
用“箱式”模型结构描述了建筑颜料及填料表面存在的各种活性基团（包括表面羟基团、不稳定的离子、水分子等）。着重分析了建筑颜料和填料的表面酸碱性及电子转移对基质材料（有机高分子材料）老化过程的催化作用。论述了颜料和填料的表面改性，提出了改性方法。
Abstract Various active groups existing on the sur-face of pigments or fillers for building, in-cluding surface hydroxyl groups, unstableions and water molecules etc., are describedby means of a 'box' structure model. Par-ticular attention is placed on the analysis ofthe influence of pigments or fillers surfaceacidity or basicity and the electron transfer-ence on its catalytical effect in the agingprocess of binders (organic high polymers).Principles of surface pretreatment are dis-cussed and some special modification meth-ods are proposed.
