Hydrophilic plastic filler liquid-phase oxidation modification method

The invention discloses a hydrophilic plastic filler liquid-phase oxidation modification method. The method comprises the following steps that a plastic filler is put in an oxidizing agent for liquid-phase oxidation modification, natural airing is conducted, and a product is obtained, wherein the oxidizing agent is concentrated sulfuric acid or nitric acid or a mixed solution of concentrated sulfuric acid and nitric acid. The hydrophilic plastic filler liquid-phase oxidation modification method starts from material modification, and a hydrophilic group is introduced according to the hydrophobicity of the material surface, the hydrophilicity of the material surface is improved, and the method that the plastic filler is soaked in acid solutions at different temperatures, time and concentration, and the hydrophilicity of the plastic filler can be improved can also be used for improving the hydrophilic performance of the plastic filler surface. 本发明公开了种亲水性塑料填料液相氧化改性方法，包括如下步骤：将塑料填料放入氧化剂中进行液相氧化改性后，自然晾干得到产品，所述氧化剂为浓硫酸
