Description
Technical field
The present invention relates to hydrophobic oleophobics to paint field, especially a kind of hydrophobic oleophobic finishing coat.
Background technique
Small advertisement refers to the advertisement illegally printing, distribute, putting up, spraying more.It puts up and is sprayed on electric pole, enclosure wall even resident
Various small advertisements in building aisle are referred to as " psoriasis ", and there are also many suspected illegal crimes, such as recruitment swindleness for content therein
It deceives, false Medical Advertisement etc..
Urban district small advertisement and unrest put up phenomenon and remain incessant after repeated prohibition, and become the scar on the face of city, pollute city appearance environment, influence
Civilized city's image, this is also always the difficulties for being stranded our administration of city appearance work, and small advertisement influences city image,
It scrawls the small advertisement disorderly pasted and adverse effect is caused to city appearance.Increase municipal pollution.Paper is wasted, that generally sticks is wide
It accuses, is difficult to tear at all, leads to not recycle, cause to waste.Some small advertisements spread false information, can make not resolving ability
Minor receives injury.
When traditional small advertisement is administered, people often scratch manually, and working efficiency is slow, and cold or hot in weather
It when summer, can not be scratched manually, small advertisement is caused to stop for a long time, hydrophobic oleophobic paint can lose thin for about half year in the market
The performance of water oleophobic.
Therefore research and development hydrophobic oleophobic finishing coat with long service life, improve scribble of the oil pen on wall and all kinds of buildings with
And the stickup phenomenon of small advertisement reaches domestically leading level to improve market popularity.
Summary of the invention
The purpose of the present invention is to solve the above problems, devise a kind of hydrophobic oleophobic finishing coat.
Realize above-mentioned purpose the technical scheme is that, a kind of hydrophobic oleophobic finishing coat, including component A and B component；
Wherein, component A includes: fluorinated silicone modified acrylic emulsion 25-70 parts, 0-2 parts of fluorine silicon levelling agent, organosilicon levelling agent
0-3 parts, 0-5 parts of defoaming agent, 0-5 parts of drier, 0-5 parts of polyurethane thickener and 25-55 parts of water；
Wherein, B component includes: 30-120 parts of isocyanate curing agent.
Preferably, further, 60 parts of the fluorinated silicone modified acrylic emulsion in the component A, domestic new material,
Reduce surface tension.
Preferably, further, 0.5 part of fluorine silicon levelling agent in the component A, can reduce surface tension.
Preferably, further, 0.3 part of the organosilicon levelling agent in the component A, can reduce surface tension.
Preferably, further, 0.3 part of the defoaming agent in the component A, defoams in spraying process, prevention
Foam has an impact construction effect.
Preferably, further, 0.3 part -5 parts of the drier in the component A is less than 0.3 part of rate of drying
Slowly it is poor to do solid work the good water-fast salt spray resistance of slow difference of hardness flexibility, the fast hardness height of reaction speed is done solid work higher than 0.5, flexibility is poor.
Preferably, further, 0.5 part -2 parts of the polyurethane thickener in the component A, does not have lower than 0.5 part
Effect is higher than 2 parts of wastes.
Preferably, further, 100 parts of the B component isocyanate curing agent, 100 parts of curing agent are added
Difference of hardness, flexibility is poor, and rate of drying is fast, adds and has lacked that the good poor water resistance flexibility of flexibility is good, and weatherability is poor.
Preferably, further, the component A group and B component proportion are 10:1
A kind of hydrophobic oleophobic finishing coat made using technical solution of the present invention,
1, small advertisement and oiliness gel ink pen cannot be pasted and be scribbled in this coating surface；
2, the production model for changing existing traditional paint, using water instead is diluent, reduces the discharge of pollution sources.
Specific embodiment
The present invention is specifically described, a kind of hydrophobic oleophobic finishing coat, including component A and B component；
Wherein, component A includes: fluorinated silicone modified acrylic emulsion 25-70 parts, 0-2 parts of fluorine silicon levelling agent, organosilicon levelling agent
0-3 parts, 0-5 parts of defoaming agent, 0-5 parts of drier, 0-5 parts of polyurethane thickener and 25-55 parts of water；Wherein, B component includes:
30-120 parts of isocyanate curing agent；60 parts of fluorinated silicone modified acrylic emulsion in the component A, domestic new material reduce table
Face tension；0.5 part of fluorine silicon levelling agent, can reduce surface tension in the component A；Organosilicon levelling agent 0.3 in the component A
Part, surface tension can be reduced；0.3 part of defoaming agent in the component A, defoams in spraying process, and pre- foam-resistant has an impact
Construction effect；0.3 part -5 parts of drier in the component A, it is good that less than 0.3 part slow drying speed does solid work slow difference of hardness flexibility
Water-fast salt spray resistance is poor, and the fast hardness height of reaction speed is done solid work higher than 0.5 part, and flexibility is poor；Polyurethane thickener in the component A
0.5 part -2 parts, do not have effect lower than 0.5 part, is higher than 2 parts of wastes；100 parts of the B component isocyanate curing agent, 100 curing agent
Difference of hardness is added, flexibility is poor, and rate of drying is fast, adds and has lacked that the good poor water resistance flexibility of flexibility is good, and weatherability is poor；Institute
Stating component A group and B component proportion is 10:1.
The technology of this programme focuses on:
1, the fluorinated silicone modified acrylic emulsion of component A, organosilicon auxiliary agent, defoaming agent, drier, pure water.B component isocyanic acid
