Abstract：White carbon black was prepared from limekiln gas and water glass by carbonization method with addition of the surfactants as modifiers such as polyethylene glycol (PEG6000), neopelex (SDBS) and carboxymethylcellulose which were used to modify the prepared product by organic wet method. Silicon-alcohol groups as surfactant of white carbon black are taken by organic groups to advance the affinity to polymer colloidal particles and the reactivity. The priority order of product characteristics (yield of white carbon black, specific surface area, sorption rate of DBP) in single matching of the modifiers is polyethylene glycol (PEG6000) > carboxymethylcellulose > neopelex (SDBS). The priority order of product characteristics in multi-matching of the modifiers is polyethylene glycol (PEG6000) > multi-modifiers > neopelex (SDBS). The product grain size distribution was examined with scanning electron microscope, and infra-red spectrogram in the single matching and multi-matching of the surface modifiers. The experimental results can provide basic data and technical guidance for preparing the white carbon black of surface with excellent features.
