Problems solved by technology

[0004] Patent CN105238219A discloses a preparation method of an oleophobic cathodic electrophoretic coating, although it is proposed to reduce the surface energy of the coating film through ultra-fine treated silica, and combine a small amount of fluorosilane additives to achieve an oleophobic and non-sticky surface of the coating film. effect, but the disadvantage is: the ultra-fine treated silica is a kind of water-insoluble inorganic filler, which is in the state of suspension and dispersion in the coating system. Holes and other disadvantages affect the use

Embodiment approach

[0030] An oleophobic cathodic electrophoretic coating, which uses polymer resin, solvent, dispersant, pure water, pigment, and fluorocarbon resin as raw materials, and the ratio of each component of the raw material is as follows in terms of mass percentage: 25-35% polymer Resin, 0.5-2.5% solvent, 1-5% dispersant, 50-60% pure water, 5-10% pigment, 1.0-3.0% fluorocarbon resin. Mix the polymer resin with solvent, dispersant, and pure water in a sand mill disperser and stir evenly, then add the pigment and stir evenly, then add zirconium beads, grind until the coating fineness is not greater than 15 microns, and finally add fluorine The carbon resin is evenly stirred and filtered to obtain an oleophobic cathodic electrophoretic coating. Described polymer resin is cationic water-based epoxy resin (such as the EP-20 type water-based epoxy resin emulsion produced by Jinan Shenzhou New Material Technology Co., Ltd.), cationic water-based acrylic resin (such as the EA9270 type water-b...

Abstract

The invention discloses an oleophobic cathode electrophoresis coating. Polymer resin, a solvent, a dispersant, pure water, a pigment and fluorocarbon resin are adopted as raw materials. The oleophobic cathode electrophoresis coating is prepared through the following steps: mixing the polymer resin with the solvent, the dispersant and pure water, uniformly stirring and mixing above materials in a sand milling disperser, adding the pigment, uniformly stirring and mixing all above materials, grinding the mixed materials until the fineness of obtained coating is not greater than 15[mu]m, adding the fluorocarbon resin, uniformly stirring the coating and the fluorocarbon resin, and filtering the obtained mixture to obtain the oleophobic cathode electrophoresis coating. The oleophobic cathode electrophoresis coating has the advantages of simple preparation technology, good running stability of a coating system, and realization of excellent oleophobic effect of a dried film formed by using the oleophobic cathode electrophoresis coating.

Description

technical field [0001] The invention relates to an electrophoretic paint, in particular to an oleophobic cathodic electrophoretic paint. Background technique [0002] Electrophoretic coatings originated in the 1930s, and began to study synthetic cationic resins in the mid-1960s, and were used as primers for household appliances requiring high corrosion resistance in the early 1970s, and then gradually developed Cathodic electrophoretic coatings with higher corrosion resistance and decorative effects are widely used in It is used in the motor vehicle industry, and is widely used in building materials, light industry, household appliances and other industrial fields, as well as surface anticorrosion and decoration of hardware and handicrafts. [0003] Kitchen appliances, such as range hoods, are prone to oil stains on the surface in the environment in which they are used. The prior art generally adopts powder epoxy spraying, and its disadvantage is that it is not oleophobic ...
