Description
Technical field
The present invention relates to a kind of electrophoretic coating, more particularly to a kind of oleophobic cathode electrophoresis dope.
Background technology
Electrophoretic coating is come from the 1930s, begin one's study synthesizing cationic type resin from middle 1960s,
And be used to that corrosion resistance is required to make priming paint on high household electrical appliance in early 1970s, it then gradually has developed resistance to
Corrosion energy higher and the cathode electrophoresis dope with decorative effect, since it is with excellent anticorrosive property, high permeability ratio, height
The features such as levelability, high-decoration and application high degree of automation, few pollution from coatings, it is widely used in automotive industry, and
Promote the use of the surface anticorrosion and decoration of the industrial circles such as building materials, light industry, household electrical appliance and hardware and craftwork.
Kitchen appliance such as smoke exhaust ventilator due in its use environment surface easily speckle with greasy dirt.The prior art is usually
It is sprayed using powder epoxy, the drawback is that not oleophobic, not anti-sticking, causes smoke exhaust ventilator to need periodically to be removed in use
Oil is cleaned and made troubles.It is current preferable solution that oleophobic processing is carried out to smoke exhaust ventilator surface.Foreign countries also have with poly-
Perfluor or poly- fluoroalkane ether are main film forming substance, but its is with high costs.Although electrophoretic coating is efficient, at low cost, one
As electrophoretic coating and powdery paints not oleophobic, not anti-sticking.
Patent CN105238219A discloses a kind of preparation method of oleophobic cathode electrophoresis dope, although proposing by super
The tripoli of micronization processes reduces the surface energy of film, and reaches film coated surface oleophobic, viscous effect with reference to a small amount of silicon fluoride auxiliary agent
Fruit, but shortcoming is：The tripoli of ultra fine is a kind of inorganic filler not soluble in water, and suspended dispersed is in coating system
State, easily occur settling and film being caused the disadvantages such as particle, shrinkage cavity occur so as to influence to use in the long-term use.
The content of the invention
It is an object of the invention to provide a kind of oleophobic cathode electrophoresis dopes, and preparation process is simple, coating system operation is steady
There are excellent oleophobic effects after qualitative good, film drying.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of oleophobic cathode electrophoresis dope, using fluoropolymer resin, solvent, dispersant, pure water, pigment, fluorocarbon resin as original
Fluoropolymer resin and solvent, dispersant, pure water are blended in after being stirred and evenly mixed in sand milling dispersion machine, then add in pigment by material
It stirs and evenly mixs, is ground to coating fineness no more than 15 microns, is eventually adding fluorocarbon resin and stirs evenly, filter to get to oleophobic
Cathode electrophoresis dope.
Preferably, by mass percentage, the proportioning of feed components is as follows：25~35% fluoropolymer resin, 0.5
~2.5% solvent, 1~5% dispersant, 50~60% pure water, 5~10% pigment, 1.0~3.0% fluorine carbon tree
Fat.
Preferably, the fluoropolymer resin is cation water-based epoxy resin, cation water-based acrylic resin, sun
One or more of ion aqueous polyurethane.
Preferably, the solvent is ethylene glycol alcohol ethers solvent, propylene glycol alcohol ethers solvent, aromatic hydrocarbon solvent, low
It is one or more of in molecule dicarboxylic acids dimethyl ester solvent.
Preferably, the dispersant is one or more of polyurethanes dispersant, esters of acrylic acid dispersant.
Preferably, the pigment is one or more of carbon black, titanium dioxide, barium sulfate.
Preferably, the fluorocarbon resin is cation water-based fluorocarbon resin lotion, non-ionic water fluorocarbon resin breast
One or more of liquid, solvent-based fluorocarbon resin.
Compared with prior art, the advantage of the invention is that：The tripoli of fine need not be added as functional stuffing just
The cathode electrophoresis dope of oleophobic can be prepared, preparation process on the one hand can be made simpler, effectively reduce production cost, it is another
Aspect reduces the use of tripoli, can effectively improve the stability of coating system, reduces the paint caused by being settled tripoli
Film disadvantage.The slurry that is prepared out coordinates cation water-based resin emulsion, through electrophoresis, 160~220 DEG C of bakings dry 10~
Just surface can be formed in substrate surface within 30 minutes can be relatively low, the oleophobic larger to the contact angle of edible oil, anti-stick coating.Contact
Angle refers to folder of the tangent line for the liquid-vapor interface made at gas, liquid, solid three-phase intersection point through liquid and solid-liquid boundary line
Angle is the measurement of wetness degree.Contact angle is smaller to represent that wetting effect is better, otherwise the bigger expression oleophobic effects of contact angle are more
Good, contact angle is bigger, easier when liquid is with solid contact to be removed from the surface of solids.In the painting of the present invention after edible oil volatilization
It is shunk quickly on film and forms oil droplet, thrown away by the impeller blade of smoke exhaust ventilator, there are good oleophobic effects, be smoke exhaust ventilator etc.
The ideal chose of kitchen appliance face coat.
