S3, the preparation of fluorine-containing poly-vinegar powdery paints：The relatively low branch of the fluorine content of preparation is contained into the fluorine-containing of four fluoropropyl segments
Polyester (TFPE) and CaC03. curing agent TGIC, levelling agent BYK-361N, moistening flatting agent BYK-220S in mass ratio 60:35:
4:0.5:0.5 discharges after melting mixing (100 DEG C of temperature, rotating speed 80rotor/min) 10min in mixer, crushes, then uses
180 mesh stainless steel mesh sieve, and contain the fluorine-containing polyester of ten difluoro heptyl segments for the higher branch of fluorine content
(DFPE), not fluorine-containing poly-vinegar is added to as additive（PE in), fluorine-containing poly-vinegar powdery paints is prepared.
To improve the hydrophobic oleophobic performance of polyester powder coating, the present invention is using in one epoxychloropropane of phthalic acid phenol
Reaction system in add in the method for tetrafluoro propyl glycidyl ether, synthesis branch contains the fluorine-containing polyester trees of four fluoropropyl segments
Fat (TFPE).Then it is prepared for branch using the ten difluoro heptyl glycidyl ethers with long fluorocarbon chain section and contains ten difluoro heptyl
Fluorine-containing poly-vinegar (DFPE), use1H-NMR, 19F-NMR characterizes the structure of TFPE and DFPE, and using one electricity of Oxygen bottle combustion
Pole method measures fluorine content in fluorine-containing poly-vinegar resin.By TFPE and DFPE respectively with filler;Auxiliary agent, curing agent etc. are prepared by mixing into tool
There is the fluorine-containing polyester powder coating of stronger hydrophobic oleophobic performance.
Using one butanediol of Isosorbide-5-Nitrae as initiator, phthalic anhydride and epoxychloropropane are in tetraethyl bromination amines catalysis
Under polyester resin is obtained by the reaction, synthesized end group as the polyester resin through base.Reaction temperature and catalyst are to phthalic anhydride
The influence of one epichlorohydrin reaction system reaction rate finds that reaction temperature is preferred with 100 DEG C, and catalyst amount is with 0.8wt%
It is preferred.
Tetrafluoro propyl glycidyl ether (TFGE) is added in one epichlorohydrin reaction system of phthalic anhydride to prepare
Fluorine-containing polyester (TFPE).The result shows that tetraethylammonium bromide catalysis under, using 1,4-butanediol as initiator, pass through adjacent benzene two
Reaction between formic anhydride, epoxychloropropane, tetrafluoro propyl glycidyl ether is prepared for branch and contains containing for four fluoropropyl segments
Fluorine polyester resin (TFPE) }, TFGE is successfully introduced into poly-vinegar.With one fluoride ion selective electrode method table of Oxygen bottle combustion
The fluorine content in TFPE is levied, finds to increase with the fluorine content that TFGE additions increase in TFPE.
With TFPE prepare fluorine-containing polyester powder coating (TFPEPC) curing film surface hydrophobic oleophobic performance with
The enhancing of fluorine content in TFPE and it is constant after first increasing.XPS it turns out that TFPEPC cure film surface F/C ratios be far longer than it is total
Surface enrichment has occurred in the F/C ratios of body, this fluorocarbon chain section illustrated in TFPE.And with the increase of fluorine content, cured film table
The F/C ratios in face are constant after first increasing, and when fluorine content reaches 2.45wt%, the F/C ratios of film coated surface reach equilibrium valve 0.313.
In order to reduce the usage amount of fluorine, the utilization rate of fluorine is improved, is replaced using ten difluoro heptyl glycidyl ethers (DFGE)
TFGE is prepared for the fluorine-containing polyester powder coating (DFPEPC) that branch contains long fluorocarbon chain section (ten difluoro heptyl).
DFPEPC cured films surface hydrophobicity oleophobic performance with fluorine content increase and after first enhancing it is constant, comparison TFPEPC and
DFPEPC cures the hydro-oleophobicity of film surface and consolidates as a result, finding that extension fluorocarbon chain section will be helpful to reduce in polyester powder coating
Change the required fluorine content during film hydro-oleophobicity is modified.
XPS results represent that the F/C ratios of DFPEPC curing film surfaces are far longer than overall F/C ratios.And with fluorine content
Increase, cure film surface F/C ratios first increase after it is constant.Compare the fluorocarbon chain Duan Fu that TFPEPC and DFPEPC cures film surface
For collection as a result, finding long fluorocarbon chain section, the surface enrichment effect in solidification process is more obvious.
The resistance to boiling water of cured film, acid-proof alkaline can be improved by introducing a small amount of fluorine in the polyester, but cured film is to the attached of base material
Put forth effort not occur significantly to reduce.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference numeral in claim should not be considered as to the involved claim of limitation.
