Description
Technical field
The present invention relates to fluorocarbon coating field, particularly to a kind of self-cleaning F-C paint and preparation method thereof.
Background technology
Since FEVE fluoro coatings is since China is born, owing to FEVE fluoro coatings has relatively low surface energy, thus have the polluting proofing property of excellence in theory, but utilize the high light white paint that the resin Preparation of domestic and international well-known FEVE fluororesin manufacturer becomes to carry out outdoor atmospheric exposure test, result but shows, the polluting proofing property of various FEVE is all very poor, good unlike acroleic acid polyurethane.
If the surface of paint film can lower than pollutant, pollutant are difficult to be adsorbed on paint film and show in theory, the surface tension of Organic fluoride high polymer is minimum in high polymer, and Oil repellent is more high, the surface tension of high polymer is more low, but the fluorinated volume of organic fluorine is general all below 26%, and after adding various filler and adding firming agent film forming, its coating Oil repellent also can be substantially reduced, and therefore the polluting proofing property of FEVE is that the anti-stain characteristic that can not drink pure fluororesin is mentioned in the same breath. It addition, the contact angle of FEVE film and water is typically between 85 �㡫95 ��, it is easier to produce to pollute, if therefore formula is not adjusted, considering from long-term polluting proofing property angle, FEVE coating even might as well acrylic coating and acroleic acid polyurethane coating.
The method improving coating polluting proofing property is divided into two big classes, and a class is to improve the water contact angle of coating surface, forms the super hydrophobic surface of similar lotus leaf effect; Another kind of is form hydrophilic coating at coating surface so that dirt is easily washed away.
Chinese invention patent application CN201410738031 discloses a kind of F-C paint easy to clean and preparation method thereof, have employed the fluorocarbon resin of low-surface-energy and crosslinked resin generation crosslinking curing, play the effect of fluorine atom to greatest extent, change copolymer surface property, thus playing Water-proof and oil-proof, the effect such as antirust. But the F-C paint easy to clean of this invention needs to adopt toxicity bigger and volatile organic solvent, and preparation process is complicated, equipment requirements is high, cost is high, additionally, the F-C paint easy to clean of this invention VOC residence time after construction is long, can affect greatly workmen and attendant are healthy, therefore have bigger limitation in actual use.
Summary of the invention
It is an object of the invention to provide a kind of novel fluoro-carbon paint and preparation method thereof, a kind of self-cleaning F-C paint and preparation method thereof is particularly provided.
Being mainly composed of of the self-cleaning F-C paint of the present invention:
Described paraffin is a nanometer paraffin.
Described fluorochemical is hydrofluoride or little molecular fluorine compound;
Described hydrofluoride can be one or more in alkali metal fluoride, Mercury difluoride., Argentous fluoride, antimony fluoride, Cobalt difluoride.; Described little molecular fluorine compound can be one or more in sulfur tetrafluoride, boron trifluoride, tetrafluorosilane.

Described non-fluorochemical monomer is one or more in acrylic acid, vinyl ethers, vinyl acetate, ethylene glycol monoallyl ether.
Described antifreeze is ethylene glycol or glycerol.
Described auxiliary agent is one or more in superfine heavy calcium carbonate, barium sulfate, Pulvis Talci.
The preparation method of the self-cleaning F-C paint of the present invention is:
A. by after fluorochemical monomer and non-fluorochemical monomer mixing and stirring in without water container, in system, add fluorochemical, stir under 200��400r/min rotating speed;
B. in mixture obtained in a, add emulsifying agent and paraffin, under 600��800r/min rotating speed, control temperature and control temperature 40��90 DEG C, stir 10��16h, obtain fluoropolymer seed resin;
