Technical field

The invention belongs to technical field of coatings, and in particular to a kind of self-clean type FEVE fluorocarbon coating further relates to the self-clean type The preparation method of FEVE fluorocarbon coating.

Background technique

Coating generally comprises four kinds of bases: film forming matter (resin, lotion), pigment (including extender pigment), solvent With additive (auxiliary agent).

Wherein, film forming matter is the main component of film, including grease, fats and oils processing product, cellulose derivative, natural Resin, synthetic resin and synthetic emulsion.Film forming matter further includes the nonvolatile reactive diluent in part, it is to keep coating securely attached In on coated article face formed continuous film main matter, be constitute coating basis, decide the fundamental characteristics of coating.Its In, auxiliary agent is, for example, defoaming agent, levelling agent etc., and there are also some special function additives, such as ground wetting agent；These auxiliary agents one As cannot form a film and additive amount is few, but the process of film is formed to base-material and durability plays considerable effect.Wherein, Pigment is generally divided to two kinds, and one kind is coloring pigment, and common titanium dioxide, chrome yellow etc., also kind is extender pigment, that is, is often said Filler, such as calcium carbonate, talcum powder.Wherein, solvent generally comprises organic solvent and water.It is mainly formed a film according to used in coating Coating can be divided into oil paint, fiber coating, synthetic paint and inorganic coating by substance；It can divide by coating or paint film character molten Liquid, colloidal sol, powder, has light, delustring and multicolor novelty coating etc. at latex.

Existing dirt resistance coatings are mainly based on fluorocarbon polymer and organosilicon polymer, by fluorocarbons and organic The low surface tension of silicon compound surface realizes stain resistant effect, but existing dirt resistance coatings to the utensil of Long Term Contact dust such as Air-conditioning, air purifier, the surfaces such as dust catcher, kitchen ventilator and electrical equipment fan, dust-proof effect is unsatisfactory, often on surface And internal dust accretions, and existing dirt resistance coatings higher cost, preparation process complexity, mostly with organic solvent occurs Based on type coating, harm to the human body is larger.

In the prior art, for example, Chinese patent application CN106893414A discloses a kind of environment-friendly type FEVE fluorine carbon painting Material comprising the component of following parts by weight: 20 30 parts of FEVE lotion, 20 30 parts of epoxy radicals silicone hydride modified silicasol, film forming helps 1.0 2.0 parts of agent, 0.1 1.0 parts of thickening leveling agent, 0.2 1.0 parts and 30 60 parts of mill base of polyurethane thickener, wherein described The constituent of mill base, by weight percentage are as follows: water 33%, multifunctional assistant 0.3%, cellulose thickener 0.3%, wetting Agent 0.4%, dispersing agent 0.9%, defoaming agent 0.1%, titanium dioxide 47%, mica powder 9% and wollastonite in powder 9%.However, above-mentioned ring Guarantor's type FEVE fluorocarbon coating does not have apparent self-cleaning property and bactericidal effect.
