Abstract

The present invention discloses waterproof and oil-proof agent for papermaking industry. Acrylate monomer, cation monomer and fluroric monomer as well as dispersing emulsifier, initiator and stabilizer are emulsion polymerized under the synergistic action of ultrasonic wave irradiation and microwave irradiation to prepare the emulsified waterproof and oil-proof agent. The waterproof and oil-proof agent is added into the paper pulp or painted to the surface of paper, and can raise the water preventing and oil preventing function obviously.

Description

technical field [0001] The invention relates to a paper waterproofing and oil-repellent agent used in the papermaking industry, in particular to a method and application of a fluorocarbon oil-repellent agent prepared by emulsion polymerization through the synergistic action of ultrasonic waves and microwaves. Background technique [0002] In our production and living process, we often encounter many substances that are easy to cause oil or dirt, including some low-viscosity liquid grease, high-viscosity semi-solid grease, oil / water dispersion emulsion, water-soluble macromolecules or colloidal substances, etc. . In order to obtain the oil-repellent effect, polymer materials that degrade extremely slowly in nature are generally used. Although they meet the waterproof and oil-proof requirements of packaging, the discarded plastic packaging materials after a large number of uses have caused great white pollution to the human environment. This pollution has become a major publ...
