Abstract
Bamboo vinegar and sulfuric acid are used as acidifier and the method of precipitation is adopted to synthesize the antibacterial white carbon black. Orthogonal experiment was carried out to investigate the influence of reaction temperature, the amount of bamboo vinegar, additive amount of polyethylene glycol, the concentration of sodium silicate and amount of priming water on the oil absorption value of white carbon black. The analysis of orthogonal experimental results shows that influence of temperature, amount of priming water and the additive amount of PEG on oil absorption value is extremely remarkable. The influence of the amount of bamboo vinegar is remarkable, but the concentration of sodium silicate is indistinctive. It is verified through experiments that the specific surface area and oil absorption value of product is high, and its antibacterial effect is good.
