AI Technical Summary

Technical Problem

The prior art has environmental problems and poor results when imparting water and oil repellent properties to food packaging paper, especially due to environmental pollution problems of fluoride treatments, and an alternative solution is urgently needed.

Method used

A co -containing cluster with fluoride is adopted, which has excellent water decentralization through special design to handle paper, thereby giving it efficient water and oil performance. The cluster is formed by polymerization by a specific monomer I and single II. The structured and mass content of the single I and the monomer II are specific to ensure the performance of the polymer.

Benefits of technology

The efficient reproduction and oil treatment of paper are realized, and this method is environmentally friendly and cost -effective. It is suitable for multiple paper treatment methods, including surface coating, surface glue and wet parts.

Abstract

The present invention discloses a copolymer, a paper treatment agent containing the copolymer and a paper product treated with the copolymer. The copolymer can be applied to the treatment of paper fiber products to make the paper products have the function of water and oil repellency. The copolymer of the present invention comprises two monomers, monomer I is an acrylic monomer modified by silicone, and monomer II is an acrylic monomer containing amino groups. The water-dispersible treatment agent can be applied to paper product coating, surface sizing and wet-end addition.
