Description
Technical field
The invention belongs to polymeric material fields, more particularly to water-soluble and suitable for water-based ultraviolet (UV) curable coating
Auxiliary agent, and in particular to a kind of antifouling anti-graffiti auxiliary agent of water solubility and its application.
Background technology
Water-based ultraviolet (UV) curable coating has curing rate fast, saves the energy, and environmental pollution is small, and cured product performance is good,
The advantages that being suitable for high-speed automated production is the main substitute of traditional coating (especially solvent based coating), increasingly by
To the attention of coating circle.However, containing a large amount of carbonyl, amino isopolarity function since waterborne UV coating is formed by paint film
Group, leads to the anti-scribble poor performance of the anti-pollution of paint film.Improve antifouling, the anti-sticking and anti-graffiti property of existing waterborne UV coating coating surface
Can, it is always the hot and difficult issue of coating research, the 3C for being particularly applied to the surfaces such as computer, communication and consumer electronics is applied
The rigidity-increasing dope of material and the optics film surface such as display and touch screen is also useful for the anti-graffiti painting of prevention city psoriasis
The low surface energy coatings such as material.Technically, the hydrophobic oleophobic function of material surface is realized, there are mainly two types of approach, when
Low-surface energy substance, mainly Organic fluoride and organosilicon are added in material surface；Second is that building coarse structure in material surface.In the least
It is undoubtedly that a kind of efficient anti-pollution auxiliary agent is added in research in existing formulation for coating material, without changing the other of original coating
Performance is a kind of quick, efficient and practical method.
Perfluoropolyether (PFPE) is a kind of fluorine of safety and environmental protection without containing environment cumulative bad chemical compositions such as PFOA, PFCS
Source.It is poor with other hydrocarbon component intermiscibilities in coating, floats on the surface of paint film in film forming procedure in meeting, and then reduce paint film
Surface energy finally realizes the functions such as grease proofing, waterproof and dustproof.It is poly- that Chinese invention patent CN106220839A discloses a kind of perfluor
Anti-graffiti auxiliary agent of ether and preparation method thereof, structural formula is as follows：
Wherein, n is natural number and 2≤n≤30；X is R1N(R2)-or-HN-R2, R1、R2Respectively containing polyurethane structural
Substituent group, and alcoholic extract hydroxyl group is contained in the end of X.However this compound is difficult to apply mainly containing groups such as polyurethane structurals
In UV photocureable coating, the poor compatibility in UV photocureable coating, it is difficult to play its antifouling anti-graffiti function.
For another example patent of invention CN2005800145739 discloses a kind of perfluoropolyether-modified acrylic acid with antifouling effect
Ester, however after the compound of this patent disclosure is applied to coating, coating is in occurring UV Light Curings, the oxygen meeting in air
Oxygen inhibition effect is generated to solidification, while the adhesive force and compatibility of this compound and paint film are all poor, and then can be in product
Perfluoropolyether occurs during use and is constantly detached from coating surface, the durability for eventually leading to paint film anti-pollution function is deteriorated, because
Although this its realize certain antifouling wearability, effect is still undesirable, and the compound can not be dissolved in aqueous UV
Coating, that is, may not apply to the antifouling antigraffiti properties of waterborne UV coating improves.

Afterwards, the spot of coating surface is wiped with dry paper handkerchief, whether there are spots for observation coating surface.Classification mark is carried out according to following standard
Show：
1 grade：Expression can be easy to wipe spot, and without any residual inside paint film；
2 grades：Expression can wipe spot, but relatively elaborate, and without any residual inside paint film；
3 grades：Expression can wipe spot, but have the ink marks of infiltration inside paint film；
4 grades：Expression cannot wipe spot.
Contact angle test method：Test piece without any abrasion is placed in contact angle instrument (model：DSA30, German Ke Lvshi
Co., Ltd provides) on, using deionized water and dodecane as tested media, test droplets volume is 4 μ L, record 3 dropping liquids drop
Contact angle values, and take the arithmetic mean of instantaneous value of 3 test datas.
Rub durability evaluation：Test piece is fixed on wear-resistant tester to (ESIDA-NM-002, the easy generation in Shenzhen reach instrument
Equipment Co., Ltd provides), bundle polypropylene non-woven fabric (model on contact head friction probe：B95, the auspicious industrial material of Jiangxi sky
Expect Co., Ltd)；Probe top applies 500g test loads, test trip 20mm, 10 beats/min of sample speed；Wear testing into
Row after twenty minutes, stops experiment, and the contact angle on surface is lost.
It is anti-scribble property, contact angle, rub durability test result referring to table 1.
Table 1 is the formula and the performance test results of coating
It is compared by coating sample S1, S2, S3, S4, S5, S6 and blank sample coating S7, it can be seen that in aqueous painting
PFPE is introduced in material formula can be obviously improved antigraffiti properties, and the paint film for being not introduced into PFPE does not have a pollution resistance, and oleic acid can be
Coating surface is sprawled completely, and permanent pen prepared Chinese ink can pollute paint film and cannot wipe；Compared with S6, S1, S2, S3, S4
With the contact angle with higher water and oleic acid after the abrasion of the coating surface of S5, this is because water paint S1, S2, S3, S4 and
Multiple acrylate UV photocurings active function groups and polysiloxanes segment are introduced in S5, are had more with water paint ontology
High intermiscibility and adhesive force makes water paint have higher wear-resisting property, and keeps perfluoropolyether segment relocation site more thorough,
Greatly improve antifouling antigraffiti properties；It is found simultaneously by the comparison of water paint sample S1, S4 and S5, in paint film
The increase of the anti-scribble auxiliary agent content of PFPE base anti-pollutions contributes to the promotion of antifouling property, but increase rate with content variation not
Obviously, it was demonstrated that pollution resistance improves not after the content of the anti-scribble auxiliary agent of PFPE bases anti-pollution in aqueous coating formulation reaches a certain level
Obviously.Experimental result explanation：It is provided by the present invention to have both that the water-soluble and active water solubility of UV photocurings is antifouling anti-graffiti to be helped
Agent can have good intermiscibility, adhesive force with aqueous UV paint films, perfluoropolyether segment relocation site can be made more thorough, therefore add
Its paint film has good antifouling property and wear-resisting property.
The present invention is described in detail above, its object is to allow the personage for being familiar with this field technology that can understand this
The content of invention is simultaneously implemented, and it is not intended to limit the scope of the present invention, and the present invention is not limited to above-mentioned implementations
, equivalent change or modification made by all Spirit Essences according to the present invention should be covered by the protection scope of the present invention.
