Description
Technical field
The present invention relates to paint fields, and in particular to the preparation of water paint, more particularly to a kind of aqueous fluorine of automatically cleaning
Carbon building coating and preparation method.
Background technique
Traditional solvent type coating contains a large amount of organic volatile (abbreviation VOC) during its manufacture and use, gives ring
Border brings more or less pollution and destruction, causes damage to human body.The development of coating is constantly improving human material's life
While production, life requirement, also deteriorate environment rapidly.Resin used in water paint is synthesized by carrier of water, at present
It is widely applied to have water-borne acrylic coatings, aqueous polyurethane coating etc..Compared with solvent based coating, it the biggest advantage is to
VOC content is lower, free from extraneous odour, does not burn and toxicity is low, but its there is also water resistances and poor solvent resistance, hardness low, gloss and
The disadvantages of richness difference and slow drying speed and weak substrate adhesive force.
In recent years, fluorocarbon coating be widely used in building, anti-corrosion, highway, railroad bridge, vehicular traffic, ship and
The fields such as ocean engineering facility have great application value.Fluorocarbon coating is primarily referred to as with pure fluororesin or by modified
Fluororesin be main film forming substance the coating with specific function, show brilliant pair thin property, weatherability, durability,
Resistance to acid and alkali, rotproofness, insulating properties and non-adhesive etc. are a kind of outstanding new special coating.
Chinese invention patent application number 201610954435.9 discloses a kind of preparation side of automatically cleaning aqueous fluorocarbon coating
Method belongs to technical field of paint preparation.The invention is first with butyl titanate, acetylacetone,2,4-pentanedione ethanol solution, ethyl orthosilicate etc.
It is mixed to prepare colloidal sol, is then aged filtering, gained filter residue is made through drying, grinding, calcining through SiO2Modifying titanium dioxide
Nano-powder, then double thinization processing are carried out to it by tridecafluoro-n-octyltriethoxysilane, finally by water-base fluorocarbon emulsion tree
Rouge, talcum powder, double thinization processing modifying titanium dioxides and auxiliary agent are uniformly mixed, that is, are available from clean water fluorocarbon coating.
Chinese invention patent application number 200610029160.4 discloses a kind of lotus leaf effect self cleaning fluorocarbon paint.It should be certainly
Fluorocarbon coating is cleaned mainly by organic-silicon-modified fluorocarbon resin, curing agent, hydrophobic particles, pigment, filler, auxiliary agent and solvent group
At.The weight ratio of each component is organic-silicon-modified fluororesin: curing agent: hydrophobic particles: pigment: filler: auxiliary agent: mixed solvent=
1:0.1~0.3:0.03~0.1:0~0.35:0~0.1:0.01~0.05:0.1~0.3。
Chinese invention patent application number 201710977587.5 discloses a kind of preparation method of self-cleaning fluorocarbon paint.The hair
The silicon fluoride of bright middle hydrolysis is mixed with titanium dioxide and high speed dispersion, obtains the modified titania nanoparticles in surface, then
Varnish mixes with carbon nanotubes dispersion liquid, micro- solidification obtains self-cleaning fluorocarbon paint, and silicon fluoride is by titanium dioxide granule and fluorine carbon tree
The combination of rouge increases, and silicon fluoride molecule hydrolyzes in acid condition, and due to hydrogen bond action, the silicon fluoride molecule after hydrolysis is inhaled
Be attached to titania nanoparticles surface, the carbochain in silicon fluoride molecule due to the protection by fluorine original physical barrier effect, other
Atom is not easy to invade, so silicon fluoride has good chemical stability and low surface free energy, silicon fluoride surface coating layer subtracts
Small TiO2Effect of the nano particle to the Van der Waals force and hydrogen bond of water greatly increases the contact angle of surface of the paint film, to show
Super-hydrophobicity out can significantly improve stain resistant, have a extensive future.

Method.Key step includes: that diisocyanate is first reacted to the polyethyleneglycol for adding metering to a certain extent with trihydroxylic alcohol
Ether react the diisocyanate of obtained branched modification, then reacts modifying diisocyanates with fluorocarbon resin, in fluorine carbon
Hydrophilic molecules group is introduced on resin, obtains a kind of self cleaning fluorocarbon resin.The self cleaning fluorocarbon resin is matched according to a conventional method
Coating is made, hydrophilic molecules group is migrated to coating surface after construction, makes film coated surface hydrophiling, to have automatically cleaning
Function；Fluorocarbon resin forms fine and close film in coating bottom simultaneously, prevents pollutant from entering inside film with rainwater and is formed permanently
Pollution.
According to above-mentioned, the fluorocarbon coating in existing scheme is based on solvent type, containing toluene in coating, dimethylbenzene and ethylbenzene
The substance that equal organic solvents and free vulcabond etc. are harmful to the human body, product is in production and transport and storage process
Fire protection requirement is very strict, and the man power and material of investment is higher, and such coating self-cleaning function is poor.
Summary of the invention
Do not have self-cleaning function for the wider aqueous fluorocarbon coating of current application, resistance to soiling and antibiotic property are poor, shape
It is poor at paint film wearability, and the toxic solvent contained in coating at branch to the hurtful defect of human body environment, the present invention
