Abstract

The invention discloses an anti-icing fluorocarbon emulsion. The anti-icing fluorocarbon emulsion is prepared from the following raw materials in percentage by weight: 10.00-50.00 percent of fluorinated monomer, 0.00-10.00 percent of modified monomer, 0.50-5.00 percent of inorganic nanometer particle, 0.00-2.00 percent of an initiator, 0.50-5.00 percent of an emulsifier, 0.00-20.00 percent of a cosolvent and the balance of water. The invention also discloses a preparation method of the anti-icing fluorocarbon emulsion. The anti-icing fluorocarbon emulsion is simple in production process and excellent in performance and is safe and environmentally friendly.

Description

technical field [0001] The invention relates to a fluorocarbon resin emulsion, in particular to an anti-icing fluorocarbon resin emulsion and a preparation method thereof. Background technique [0002] Snow and ice will cause losses in many fields, such as road blockage, power failure, aircraft grounding, and wind turbine overload operation. Anti-icing technology mainly refers to prolonging the freezing time of supercooled water, so that the water has enough time to separate from the freezing surface by gravity, centrifugal force, wind force, etc. before freezing, so as to achieve the purpose of preventing freezing, which requires lowering the surface Surface energy and adhesion to ice and water. [0003] Chinese patent CN 102492945B discloses a bionic micro-nano composite structure anti-icing surface and its preparation method. The method is a combination of material surface nanostructure and low surface energy modification, but the process cost is high; Chinese patent app...
