Abstract
A kind of high water resistance hard-gloss paint, belong to technical field of coatings, characterized in that the coating is made of the raw material of following weight percent: styrene 12-14%, acrylic acid 1-3%, butyl acrylate 15-20%, methyl methacrylate 6-8%, emulsifier 0.5-0.7%, initiator 0.2-0.5%, ionic liquid 2-5%, trifluoroethanol 1-2%, deionized water complement to 100%.The micro-nano structure (micron or nanoscale mastoid process structure) of coating film forming rear surface of the invention, this micro-nano structure can be improved the contact angle of water droplet and coating surface and improve the incident angle of incident light, good waterproof performance and have high gloss.
Description
Technical field
The present invention relates to a kind of high water resistance hard-gloss paint, belong to building coating technical field.
Background technique
Coated on building, decorative architecture object or the coating for protecting building, it is referred to as building coating.Building coating has
Decoration functions, defencive function and livability improve function.Specific gravity shared by various functions is not quite similar because using purpose different.
Decoration functions are the functions that its appearance value is improved by the beautification of building.It mainly include plane color, pattern and light
The design design and the design of three-dimensional pattern design of damp aspect.
There are many factor for influencing building coating glossiness, one of them is the degree of roughness of film forming rear surface, rough surface
Micro-structure influences the incident angle of light, and in general, incidence angle is bigger, and the intensity of reflected light is higher, thus its glossiness is higher.
Ionic liquid is exactly as its name suggests the salt chemical combination that is in a liquid state at room temperature completely as composed by zwitterion
Object.It is different from traditional solid salt, there is designability, different zwitterion energy with melting molecules of salt existing for liquid condition
Enough it is combined into miscellaneous ionic liquid.By selecting different zwitterion, or be introduced directly into specific functional group into
Row modification, is adjusted the property of ionic liquid, such as fusing point, viscosity, hydrophobicity, to meet different needs.Ionic liquid
Because the saturated vapor pressure obviously not measured, thus using ionic liquid than using traditional chemical solvent to be more in line with environment
Friendly Green Development theory.There is ionic liquid designability can design kind by adjusting different zwitterions pair
Class is different, and the special ionic liquid for meeting different needs comes.
It has been found that specific ionic liquid can form a film in styrene-acrylate emulsion coating, coating forms a film the micro- of rear surface
Micro-nano structure (micron or nanoscale mastoid process structure) can be improved the incident angle of incident light, and coating surface glossiness is high.
Summary of the invention
The present invention provides a kind of high water resistance hard-gloss paint, by adding specific ion liquid, coating film forming rear surface
Micro-nano structure (micron or nanoscale mastoid process structure), this micro-nano structure can be improved water droplet and coating surface contact angle and
Improve incident light incident angle, good waterproof performance and have high gloss.
The present invention it is specific the technical solution adopted is that:
A kind of high water resistance hard-gloss paint, characterized in that the coating is made of the raw material of following weight percent:
Wherein, the structural formula of the ionic liquid are as follows:
In formula: R1, R2, R3 can be H, F, CF3, the linear paraffin of the saturation of C1-C4.
Wherein, the emulsifier is the mixture of lauryl sodium sulfate and n-amyl alcohol according to weight ratio 1:2~3, application
People has found that the emulsifier of this compounding can be improved paint film water resistance and hardness.
Wherein, the initiator is ammonium persulfate.
The preparation method of the high water resistance hard-gloss paint, includes the following steps:
1) ionic liquid is uniformly mixed at 40-50 DEG C with trifluoroethanol, is cooled to room temperature spare；
2) in emulsion reaction tank, lauryl sodium sulfate and n-amyl alcohol are proportionally added into deionized water, stirred；Monomer
In tank, styrene, acrylic acid, butyl acrylate, methyl methacrylate are uniformly mixed, spare, this mixed liquor is known as mixed
Close monomer；
In emulsion reaction tank, the mix monomer progress seeding polymerization of initiator and 1/10 is added, then heats to 85 DEG C, drop
Add remaining mix monomer, is reacted 2-4 hours at 85 DEG C after being added dropwise, be down to room temperature；
3) emulsion reaction tank is added in the mixture of ionic liquid and trifluoroethanol, be uniformly mixed to get the high water resistance
Hard-gloss paint.
Compared with prior art, the invention has the advantages that
1) present invention is water paint, can be reduced environmental pollution, improves operation and construction environment；
2) coating film forming rear surface have micron or nanoscale mastoid process structure, this micro-nano structure can be improved water droplet with
The contact angle of coating surface makes water droplet easily fall off in coating surface, good waterproof performance；
3) micro-nano structure of coating surface of the present invention can be improved the incident angle of incident light, have high gloss.
Specific embodiment
