The invention relates to self-cleaning coating used for a building curtain wall aluminum veneer and a preparation method thereof. The coating is divided into a first component, a second component and a third component, wherein the first component is coated on the surface of the aluminum veneer for forming a bottom coating; the second component is coated on the surface of the bottom coating to form a middle coating; the third component is coated on the surface of the middle coating to form a top coating; in the first component, polyester resin and amino resin serve as film forming substance, and silicon-titanium or silicon-zirconium coupling agent is used for greatly improving adhesive force on the aluminum veneer by the bottom coating; in the second component, fluoralkene alkyl vinyl ether or ester copolymer (FEVE) fluorocarbon resin serves as the film forming substance, and therefore the coating shows excellent durability, weather fastness and corrosion resistance; and in the third component, the FEVE fluorocarbon resin and organic silicon resin serve as the film forming substance, the coating surface tension is lowered by a fluorine and silicone interpenetrating network, the hydrophobicity and the contamination resistance of the coating surface are improved, and dirt on the coating surface is easy to clean. In addition, the preparation and construction processes of a coating system disclosed by the invention are simple, and the self-cleaning coating is especially suitable for protecting an aluminum sheet curtain wall.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of building curtain wall aluminum veneer chalking paint and preparation method thereof
Background technology
As time goes on, the phenomenon that the top coat of building curtain wall loss of gloss, variable color, efflorescence can occur and come off under atmospheric environment, cause the curtain wall base material exposed, chemistry or electrochemical reaction take place when corrosive medium in the environment contacts and by corrosion in the curtain wall base material, performance is degenerated, even destroy, so the aseptic technic of curtain wall base material plays a part very important for the safety performance and the weather resistance of curtain wall base material.In addition, acid rain, various dust dirts etc. stick to the curtain wall surface easily in the atmospheric environment, acid rain is corrosive to the curtain wall top coat, the dust dirt forms ugly stain at the curtain wall outside surface, need artificial routine cleaning, if dirt be penetrated into film in, then stain can not be removed clean, piebald appears in film coated surface, has a strong impact on sight.Change this present situation, can take following measure: the one, the corrosion-resistant and strong coating of weather resistance in the curtain wall surface-coated is isolated base material and corrosive medium; The 2nd, at curtain wall surface-coated self-cleaning coat (refer to the hydrophobic or hydrophilic physical property that relies on coating itself to be had, play the coating of antifouling and easy clean effect), this kind method cost is lower, and effect is better, applied range.
There are problems in traditional building curtain wall aluminum veneer with chalking paint, as: contain strontium yellow usually in (1) coating, cause heavy metal contamination; (2) coating is to the poor adhesive force of aluminum veneer; (3) weather resistance of coating is limited, generally in 5 years; (4) coating acid resistance and contamination resistance are not high, need strong clean-out system frequent cleaning (often working aloft has certain danger); (5) the cost height of the fluorine carbon self-cleaning coating conventional PVDF(polyvinylidene difluoride (PVDF) that uses), the difficulty of changing colour, and palpus hot setting, troublesome poeration expends the energy again
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of temperature tolerance, erosion resistance, good and with low cost, the normal temperature solidified building curtain wall aluminum veneer chalking paint of contamination resistance are provided.
The present invention also will provide the preparation method of a kind of above-mentioned building curtain wall aluminum veneer with chalking paint simultaneously.
For solving above technical problem, the present invention takes following technical scheme:
A kind of building curtain wall aluminum veneer chalking paint comprises first component, second component and the 3rd component of independent packaging; Wherein, first component is used to be coated in the aluminum veneer surface to form undercoat, second component is used to be coated in described undercoat surface to form inter coat, the 3rd component is used to be coated in described inter coat surface to form finishing coat, according to the present invention, second component comprises the A component of independent packaging and the B component of independent packaging:
Described A component is mixed by following component: the mixed solvent of FEVE fluorocarbon resin 45% ~ 55%, titanium dioxide 15% ~ 25%, cobalt black 2% ~ 5%, 7/10 formula ratio, dispersion agent 0.2% ~ 0.5%, vinylformic acid levelling agent 0.05% ~ 0.15%, anti-settling agent 0.1% ~ 0.6%, organotin catalysts 0.1% ~ 0.3%; Described B component is mixed by following component: the mixed solvent of aliphatic isocyanates solidifying agent 7% ~ 10%, residue formula ratio; Described mixed solvent is mixed by toluene 5% ~ 10%, dimethylbenzene 2% ~ 5%, N-BUTYL ACETATE 8% ~ 10%; More than the percentage composition of each component with the weight of A component and B component be 100% to calculate; Wherein, described dispersion agent is acid dispersion agent; Described anti-settling agent is a wilkinite.
Above-mentioned building curtain wall aluminum veneer is to prepare first component, second component and the 3rd component respectively with the preparation method of chalking paint, and wherein the preparation of second component comprises the preparation of A component and the preparation of B component;
The preparation method of A component is as follows:
(1), gets the FEVE fluorocarbon resin of 40% formula ratio, under 500 ~ 700 rev/mins of stirrings, add the mixed solvent of 7/10 formula ratio, the dispersion agent of formula ratio, the anti-settling agent of formula ratio, the titanium dioxide of formula ratio and the cobalt black pigment of formula ratio successively, get premix;
(2), the premix of step (1) gained is transferred in the shredder, this premix is ground, to the mixed solution that obtains solid particulate fineness≤20 micron;
(3), stir with 600 rev/mins rotating speed mixed solution step (2) gained, and in this mixed solution, add remaining FEVE fluorocarbon resin, the vinylformic acid levelling agent of formula ratio, the organotin catalysts of formula ratio successively, adjust viscosity of mixed liquid to 70 ± 25 ℃/stormer viscosity of 5KU/ meter with remaining mixed solvent, and under 300 ~ 400 rev/mins rotating speed, continue to stir 8 ~ 12 minutes;
(4), be that 50 microns filter bag filters the mixed solution through step (3) with the aperture, filtrate is described building curtain wall aluminum veneer with the A component in chalking paint second component;
The preparation method of B component is as follows:
Aliphatic isocyanates solidifying agent and the remaining mixed solvent of getting formula ratio mix, and the gained mixed solution is that 10 microns filter bag filters with the aperture, and filtrate is described building curtain wall aluminum veneer with the B component in chalking paint second component.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
Building curtain wall aluminum veneer of the present invention is basic filmogen with adopting the FEVE fluorocarbon resin of hydroxyl in second component of chalking paint, each C-C key in the fluorocarbon resin molecular linkage is all tightly surrounded by the fluorine atom of screw type three-dimensional arrangement, this molecular structure can be resisted ultraviolet Degradation or the infringement of other medium, make coating demonstrate good weather resistance and weathering resistance, simultaneously, the oxygen permeability coefficient of fluorocarbon resin is extremely low, can prevent the corrosion of ground, thereby also improve the erosion resistance of coating; In addition, adopt the FEVE fluorocarbon resin as main film forming substance, coating can be cured at normal temperatures, energy-conservation saving of labor has reduced the execution of coating cost.Chalking paint prescription of the present invention is reasonable, and the preparation method is simple, can play good protective effect to aluminum veneer.
