Abstract

A fluorine-containing paper oil-proof agent is an acrylate polymer solution containing a perfluoroalkyl side chain, wherein the polymer is prepared from 55.0-85.0% of a fluorine-containing monomer, 5.0-35.0% of a fluorine-free monomer, 3.0-10.0% of a functional monomer, 2.0-10.0% of an adhesion reinforcing monomer, 0.5-2.0% of an initiator, 0.1-0.4% of a chain transfer agent, and acetone and isopropanol mixed solution by copolymerization. The polymer solution has the characteristics of strong adhesion, low consumption, good oil resistance and good water resistance. By adding the adhesion reinforcing monomer, a fluorine-containing activator can be adhered to paper fiber, and the surface property of the paper fiber is reduced, therefore, the oil proofness of the paper is improved, and the strength and stiffness of the paper are increased at the same time.

Description

technical field [0001] The invention relates to an industrially used paper waterproof and oil-repellent agent and its preparation technology, in particular to a preparation technology of a fluorine-containing paper oil-repellent agent. Packaging bags, folding paper lunch boxes, cream pastry packaging boxes and paper bags are being treated to resist the penetration of animal and vegetable oils. Background technique [0002] With the improvement of people's living standards and the continuous strengthening of environmental protection awareness, many plastic products that are difficult to degrade are gradually replaced by paper products, especially in the field of packaging. Paper products have been widely used in catering, food and other packaging and daily life. The paper products used in this field are required to have a certain waterproof and oil-proof function. As an excellent waterproof and oil-proof material, fluorine-containing paper oil-proof agent uses the special s...
