Description
Technical field
The invention belongs to the Technology field of effects on surface coating liquid or other fluids, relate to a kind of non-stick ceramic coating and coating method thereof.
Background technology
Non-viscous paint develops rapidly after being applied by invention in 1958, and be widely used in the field such as cooker, small household appliances, it is convenient to bring to people's life.Its core of existing non-sticky metallic coating is Teflon---polytetrafluoroethylene (PTFE), but many scientific research reports are pointed out in recent years, " Teflon " coating can discharge objectionable impurities in high temperature (more than 260 DEG C) situation.And tetrafluoroethylene can add ammonium perfluorocaprylate (PFOA) in process of production, after the ammonium perfluorocaprylate (PFOA) of stable chemical nature enters nature and human body, meeting long-term existence, can not decompose very soon, in experimentation on animals, the ammonium perfluorocaprylate (PFOA) of low dosage has been proved carcinogenesis and other adverse consequencess.Therefore, be badly in need of finding the surface-coated that a kind of coating that can replace " Teflon " is used as non-sticking cooking utensils for kitchen tools manufacturer.
The non-viscous paint of to be a with inorganics the be main raw material of the ceramic coating with excellent not viscosity, has the advantage that " Teflon " is incomparable in environment protection and save energy.But existing ceramic non-stick coating not viscosity, toughness, wear-resisting etc. in some is not enough, make it limit to some extent in application.Therefore, need exploitation a not only toughness, wear-resisting in meet the demands but also have the non-stick ceramic coating of outstanding representation to meet the needs of people to environmental protection non-sticky metallic coating in not viscosity.
Summary of the invention
The defect that the present invention is directed to prior art provides a kind of non-stick ceramic coating with excellent not viscosity, and the coating adopting this coating obtained is not containing materials such as PTFE and PFOA, and environmental protection and energy saving, have the non-adhesion behavior of wear-resisting, scratch resistance and excellence simultaneously.
Another object of the present invention is to provide a kind of coating method of this non-stick ceramic coating.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of non-stick ceramic coating, be by A, B two component mix 2:0.5 ~ 2 in mass ratio, wherein: component A: by the component of massfraction: silicon sol 45 ~ 100%, pigment 0 ~ 30%, filler 0 ~ 23%, dispersing auxiliary 0 ~ 2%, after mixing, grinding obtains for more than 2 hours; B component: mixed by the following component in massfraction: catalyzer 0.2 ~ 2%, silicon fluoride 3 ~ 15%, auxiliary agent 2 ~ 10%, organic solvent 0 ~ 10%, surplus is at least one silane; Described catalyzer is formic acid or acetic acid or the two mixture; Described silane has following general molecular formula R
nsi (OR ')
4-n, wherein: R is alkyl, epoxy group(ing) or aryl, R ' is C
1-C
5alkyl; N=0,1,2.
silicon sol
Silicon sol in the present invention is the dispersion liquid of nano level silica dioxide granule in water or in solvent.Silicon sol is in the present invention as one of inorganic filming substance matter, and the silane condensation dehydration of hydrolysis, obtains SiO
2reticulated structure, thus make non-sticky metallic coating have the performances such as hardness, erosion resistance, temperature tolerance.
pigment
In the present invention, pigment is heatproof pigment, uses as tinting material.Heatproof pigment in the present invention is pigment dyestuff more than 200 DEG C of nontoxic heatproof or mineral dye, can be detected by ROHS, include but not limited to: rutile, too white, titan yellow, iron oxide black, red iron oxide, cobalt black, cobalt blue, cobalt green, carbon black, pearly-lustre and aluminium silver powder etc.
filler
In the present invention, filler and physique filler, be that heatproof is nontoxic, be selected from the inorganic materials such as whisker class, fiber-like, comprise: silica powder, silicon whisker, aluminum oxide etc.
silicon fluoride
In the present invention, it is smooth and reduce surface tension that silicon fluoride improves coatingsurface as sticky auxiliary agent, ceramic coating cannot not had stickyly and performance easy to clean, its addition is 3 ~ 15%, when addition is less than 2%, viscosity is not bad, when being greater than 15%, non-adhesion behavior promotes not obvious, and cost is relatively high.
In B component, the general molecular formula of described silicon fluoride is Rf
nsi (OR ')
4-n, Rf is substituted alkyl, substituted aryl containing fluorine, and R ' is C
1-C
5alkyl; N=0,1,2.The present invention is ten trifluoro octyltri-ethoxysilane preferably.
Ten trifluoro octyl groups in ten trifluoro octyltri-ethoxysilane do not participate in reaction, ten trifluoro octyl groups make coating have the low surface tension of fluorine material and not sticky characteristic, hydrolysis can be there is in acid condition and form silanol in triethoxy, itself and silicon sol, be hydrolyzed after silane and the-OH of substrate surface can occur should, thus make silicon fluoride be connected in coating, thus the non-adhesion behavior of coating is able to good embodiment, and there is persistence.
Not sticky auxiliary agent in traditional non-stick ceramic coating generally selects silicone oil, and silicone oil has following shortcoming as not sticky auxiliary agent:
A. slightly to there will be consistency not good more for add-on;
B. the not viscosity of silicone oil has certain access times, and non-adhesion behavior does not have persistence;
C. general silicone oil does not participate in reaction, can not be combined closely with coating.
The present invention selects ten trifluoro octyltri-ethoxysilane and silicone oil mix and match to use, and by the not viscosity using a small amount of silicone oil to ensure the coating initial stage, participates in by silicon fluoride the long-term not viscosity that reaction ensures coating.
silane
