Abstract

The invention discloses a method for preparing a waste paper deinking agent by using swill-cooked dirty oil as a raw material, and belongs to the technical field of deinking agent preparation. The method comprises the following steps: removing solid matters in the swill-cooked dirty oil, filtering, adding polyacrylamide, and stirring to obtain swill-cooked dirty oil treating liquid; then, sequentially adding cyclohexanone, nonylphenol polyoxyethylene ether, sodium fatty alcohol-polyoxyethylene ether sulfide, sulfonic acid, ethanol, sodium lignin sulfonate and water under heating and stirring conditions; uniformly mixing, and further stirring at constant temperature; and finally adding sodium hydroxide, and uniformly mixing. According to the method, the swill-cooked dirty oil is used as the raw material to prepare the deinking agent, so that the swill-cooked dirty oil can be sufficiently utilized, and the problems of potential safety and environmental-protection risks of the swill-cooked dirty oil can be solved.

Description

technical field [0001] The invention belongs to the technical field of deinking agent preparation, and in particular relates to a method for preparing waste paper deinking agent from waste oil. Background technique [0002] Deinking agent is a kind of chemical or biological product that can separate paper fiber and ink. Its main function is to break the adhesion of ink to paper fiber, so that the ink is peeled off from the fiber and dispersed in water. [0003] Gutter oil generally refers to all kinds of inferior oils that exist in life, such as recycled edible oil, repeatedly used frying oil, etc. The appearance of waste oil will not only pollute the environment on the one hand, but also may cause serious food safety hazards due to the return of waste oil to the dining table on the other hand. In order to eliminate the safety and environmental hazards caused by the above-mentioned waste oil, people try to convert the waste oil into safer and useful products. Contents of ...
