Description
Technical field
The present invention relates to chemical fields, thixotropic complete mute more particularly, to not increasing in a kind of circulation construction of roller coating
UV clear finish.
Background technique
Improved day by day recently as environmental law, the common people increasingly put on the factor for influencing health such as haze, PM2.5
Schedule, for paint, requirement of the people to its feature of environmental protection and green is higher and higher, traditional paint containing diluent
It will gradually be eliminated since benzene content is higher, development that UV coating can advance by leaps and bounds in a few years from now on that different signs indicate.UV is applied
Material has difficult extinction, and when developing dumb light UV coating especially when developing complete mute UV coating, engineer is added to largely
Flatting silica, flatting silica can make paint have thixotropy.Engineer can eliminate thixotropy by adding the wetting dispersing agent of excess,
But this UV paint paint thixotropy in circulation roller coating use process can become increasing again.This will lead to paint plate face gloss and becomes
Must be lower and lower, paint plate face sophistication becomes worse and worse, and some even more can not normal reflow and construction.In order to solve UV
Coating the problem of thixotropy becomes larger during recycling.Painter's work teacher is solved by following three scheme at present:
1, the dosage of flatting silica is reduced, but the method can be such that paint finishes increase.
2, the lower flatting silica of oil absorption is replaced, same this method can also increase gloss.
3, the wetting dispersing agent of excessive addition, the method can reduce the thixotropy of paint in a short time in formula,
But thixotropy still can become increasing during recycling roller coating use.Three of the above method is without very good solution
The especially full dumb light UV paint of dumb light UV paint is in recycling roller coating use process the problem of the increase of paint thixotropy.
Summary of the invention
It is clear in view of the deficiencies of the prior art, the present invention provides thixotropic complete mute UV is not increased in a kind of circulation construction of roller coating
Finishing coat.
Technical solution provided by the invention is as follows: not increasing thixotropic complete mute clear face UV in a kind of circulation construction of roller coating
Paint, including following weight percentage components:
Epoxy acrylic resin: 5-30%,
Multifunctional polyurethane acrylic resin: 5-25 %,
Dispersing agent: 0.5-4%,
Silicon additive: 0.5-3%,
Silicon class levelling agent: 0.1-1%,
Defoaming agent: 0.1-0.3%,
Photoinitiator: 4-7%,
Reactive amines: 0.5-4%,
HDDA activated monomer: 20-40%,
TMPTA activated monomer: 3-20%,
Flatting silica: 8-18%.
Further, the silicon additive is Digao silane coupling agent.
Further, the dispersing agent is BYK-2013.
Further, the photoinitiator is 1173 photoinitiators.
The product that the trade mark of TEGO company is TEGO ADDID 900 can be used in Digao silane coupling agent,
The product that the trade mark of BYK company is BYK-2013 can be used in dispersing agent.
Epoxy acrylic resin and multifunctional polyurethane acrylic resin in formula are main film forming matters, and are provided
Physical and chemical performance required for paint film；Dispersing agent in formula is conducive to the dispersion of flatting silica；Silicon additive in formula is assisted
The dispersion of flatting silica simultaneously overcomes in paint cycle roller coating process and generates thixotropy；Levelling agent in formula mainly reduces surface
Power is for soaking levelling；Defoaming agent in formula is conducive to paint the elimination of the bubble in roller coating cyclic process and inhibits bubble
It generates；The main function of 1173 photoinitiators in formula is that absorption is ultraviolet, and light generates free radicals, and so that whole system is generated light poly-
Close reaction；Reactive amines in formula are aided initiatings, while reinforcing painted surface solidification；HDD, TMPTA activity in formula is single
Body mainly plays adjustment paint viscosity and simultaneously participates in film forming solidification, curing rate and paint film physics to entire paint systems
Performance has a certain impact；Flatting silica in formula mainly plays a part of to reduce paint finishes while have to paint feel certain
It influences.
Thixotropic complete mute UV clear finish, compared with prior art, tool are not increased in a kind of roller coating circulation construction of the invention
Standby following advantages:
The present invention is to add special silane coupling agent in the development process of complete mute UV paint.The silane coupling agent can be good at
Overcome the problems, such as that complete mute UV paint thixotropy in circulation roller coating process increases.UV low luster coating oil in circulation roller coating use process
Paint thixotropy can become increasing using the extension of time with roller coating is recycled.The invention is not reducing dumb light powder
Dosage, the type for not changing dumb light powder under the premise of not increasing wetting dispersing agent use, solve the especially full dumb light of dumb light UV coating
UV coating is in recycling roller coating use process the problem of the increase of paint thixotropy.The invention simultaneously will not make the gloss of paint
It increases, to paint without any adverse effect.By comparison, it was found that the invention can also improve paint feel and smooth degree and
Increase UV adhesive force.
Complete mute UV paint because the pigment of itself is excessively high and the high oil absorption amount of flatting silica make to be easy between powder granule because
Weak chemical bond and form spacial framework and generate thixotropy.Obtaining the shearing force between process in the middle of the roller in circulation roller coating will be light
The poly- flatting silica of micelle is completely dispersed, this can improve paint oil absorption；During roller coating because between rubber roller and plate
Scraping power be easy to destroy solid-liquid between interfacial tension, it is easy to make solid particles surface formed Adsorbed polymer layers
It falls off, this results in solid particulate matter to have the phenomenon that microcosmic precipitation, and paint is made homogeneously to enter heterogeneous, final knot from dispersion
Fruit is that resin has stronger adhesiveness that can more be coated on workpiece, and solid particle more will be blown into paint tank
In, as the paint pigment in the progress paint tank of roller coating circulation can become higher and higher, this adds increased thixotropy.And this
For silane coupling agent in invention formula other than having good wetting and dispersing viscosity reduction to act on, more important is form with flatting silica
Tie branch effect.Branch is firmly tied on flatting silica in one end of coupling agent, and the other end is compatible in resin system well, and rubber roller is scraped
Knot branch structure can not be destroyed by wiping power, and solid particle does not have microcosmic precipitation phenomenon, and paint is that dispersion is homogeneous always, will not generate face
The phenomenon that base is than increasing, i.e. paint thixotropy not will increase.
