Description
Technical field
The present invention relates to paint field, be specifically related to a kind of high color inhibition overlay film UV white and bright finish coat and preparation method thereof.
Background technology
Conventional oil-based coating, is widely used on the base materials such as woodenware, plastic cement, paper, metal.Containing a large amount of solvents in traditional coating in formula designs, in use can produce organic compound poisonous, irritating, harm healthy to people is very big, does not reaches the environmental requirement that people day by day pursue.Along with society's development, people's living standard improves constantly, and people are more and more higher to the requirement of civilian coating, it is often more important that the close attention to own health, such as toy for children paint, and children furniture paint etc., requirement can not contain hazardous substance and heavy metal.
Ultraviolet-curing paint (UVCC) is a kind of highly effective energy-conserving environmental-protecting type modernization coating using ultraviolet curing.Outstanding feature is efficiently, adapts to wide, economic, energy-conservation and environmental protection.Therefore, photocuring technology is described as green industry new technique geared to the 21st century.These advantages of UVCC have been doomed that it has the market prospect more significantly more expansive than conventional thermosetting coating.First developing curable wood coating from nineteen sixty-eight Bayer A.G, photocuring technology achieves industrialization, so far more than 40 year, but it is swift and violent in the global evolution impetus, and application constantly expands, and defines a huge industry.Present ultraviolet-curing paint achieved with the biggest development, enters a more ripe stage in the whole world.
But present existing UV paint has certain defect, causes its easy xanthochromia.The main cause of xanthochromia has two, and one is that UV paints xanthochromia, this is because some resin systems are contained within some heat (light) mutagens color substances, after being heated, molecular structure changes, and produces higher conjugated structure, makes coating color turn yellow.Two is the unstability of initiator self, some light trigger also can produce some by-products while being decomposed generation free radical by ultraviolet radiation, by-product has quinoid structure or rigidity conjugate planes are very strong, easily absorbs the sunlight of a certain wave band, and then makes coating present yellow.And the xanthochromia of coating has had a strong impact on the aesthetic property of product.And in existing UV paints, due to the defect of light irradiation apparatus, often leading to coating can not be fully cured.
Summary of the invention
The technical problem to be solved is to provide a kind of high color inhibition, can the UV white and bright finish coat of deep cure.
Further object is that the preparation method that above-mentioned high color inhibition overlay film UV white and bright finish coat is provided.
The technical problem to be solved is achieved by the following technical programs:
A kind of high color inhibition overlay film UV white and bright finish coat, is made up of the component of following percentage by weight: six degree of functionality polyurethane acroleic acids 30 ~ 50%；Two degree of functionality polyurethane acroleic acids 20 ~ 40%；Monomer 10 ~ 20%；Titanium dioxide slurry 10 ~ 20%；Light trigger 3 ~ 6%；Function additive 0.2 ~ 2%；
The six degree of functionality polyurethane acroleic acids of the present invention provide high reaction rate, hardness, wearability and materialization, provide rigidity, preferably Changxing 6145-100, Baeyer U400 etc. for paint film.And two degree of functionality polyurethane acroleic acids have the advantages that pliability is high, adhesive force is good, compounding with six degree of functionality polyurethane acroleic acids to be prevented from film the most crisp；More preferable tack is provided.
Described titanium dioxide slurry is made up of the component of following percentage by weight:
Titanium dioxide 50 ~ 70%；Six degree of functionality polyurethane acroleic acids 10 ~ 25%；Monomer 10 ~ 25%；Wetting dispersing agent 0.5 ~ 2%.
In the present invention, in advance titanium dioxide and six degree of functionality polyurethane acroleic acids and monomer are mixed dispersion, contribute to dispersed in paint film of titanium dioxide, agglomeration will not occur.
Wetting dispersing agent is the wetting dispersing agent that the art is conventional, preferably BYK163.
Further, described monomer is pentaerythritol triacrylate, and it has raising paint film response speed, strengthens hardness and the EM235 of the feature of adhesive force, preferably Changxing.
Further, described light trigger is (2,4,6-trimethylbenzoyl) diphenyl phosphine oxide, 1-hydroxy-cyciohexyl one phenyl ketone, the mixture of double (2,4, the 6-trimethylbenzoyl) phosphine oxide of phenyl.They have plyability, outstanding curing rate and the weatherability, particularly phenyl double (2,4 of excellence with resin; 6-trimethylbenzoyl) addition of phosphine oxide; after illumination, living radical is decomposed again, can cause illumination less than unsaturated double-bond, solve a deep cure difficult problem.Double (2,4,6-trimethylbenzoyl) phosphine oxide of phenyl is preferably the X-DTPO of Jingmen, Hubei sunlight Kui chemical industry.
Further, at least one during described function additive is defoamer, levelling agent.Levelling agent is the levelling agent that the art is conventional, preferably TEGO432. TEGO450, BKY337；Defoamer is the defoamer that the art is conventional, preferably EFKA2720, EFKA2721, BYK141.
Further, the fineness of described titanium dioxide slurry is less than 10 microns.
The preparation method of described a kind of high color inhibition overlay film UV white and bright finish coat comprises the following steps:
S1) light trigger and monomer are mixed according to mass ratio 1:1.8 ~ 2, be then heated to 60 ~ 80 DEG C, heat while stirring, form light trigger mixed liquor after being completely dissolved stand-by；
S2) adding in reactor by resin, titanium dioxide slurry and monomer, stir 5 ~ 30 minutes with blender, rotating speed is 800 ~ 1000 revs/min；
S3) then being added to reactor by function additive, stir 5 ~ 20 minutes with blender, rotating speed is 800 ~ 1000 revs/min；
S4) finally the light trigger mixed liquor in S1 step is added to reactor, after dispersed with stirring is uniform, obtain described high color inhibition overlay film UV white and bright finish coat.
There is advantages that
(1), the production efficiency of photocuring product is high, energy consumption is low and uv equipment investment is relatively low, easily realizes production line balance.
(2), save great amount of investment, reduce pollution, saving resource.
(3), high color inhibition overlay film UV white and bright finish coat, solve a deep cure difficult problem and the root problem of White system color inhibition of photocureable coating pigmented system.
