这种方法是,先用胶溶的方法制取透明的水溶胶,加入表面活性剂进行亲油憎水性处理,然后用有机溶剂萃取有机胶体,再经回流脱水,减压蒸馏除去有机溶剂,在低于表面活性剂分解温度下进行热处理, In this method, a transparent hydrosol is prepared by the method of peptizing first, adding a surfactant for lipophilic and hydrophobic treatment, and then the organic colloid is extracted by an organic solvent, and then the mixture is refluxed and dehydrated, and the organic solvent is distilled off under reduced pressure to obtain Below the decomposition temperature of the surfactant for heat treatment,
