Abstract
The invention relates to the technical field of coatings, in particular to a double-drying ultraviolet (UV) spraying matte primer and a preparation method thereof. The double-drying UV spraying matte primer comprises methylisobutylketone, n-butyl acetate, 1-hydroxy cyclohexyl phenyl ketone, polyester acrylic resin, an acrylic acid flatting agent, a silicon flatting agent, a wetting agent, an anti-yellowing agent, epoxy acrylic resin, 30 percent nitro cellulose solution, talcpowder, ethyl acetate (EAC), a silicon defoamer and activated polyamide wax. According to the double-drying UV spraying matte primer, nitro-cotton liquid is matched with UV resin, so that a double-drying effect can be achieved, and the limit of 'pot life' is avoided.
Description
Technical field:
The present invention relates to technical field of coatings, relate in particular to a kind of dual dry UV and spray sub-light priming paint and preparation method thereof.
Background technology:
UV paint is the english abbreviation of Ultraviolet Curing Paint, i.e. ultraviolet light cured paint, also claims light-initiated coating, photo-cured coating.Be by the automatic roller coat of machinery equipment, showering to furniture plate surface, under the irradiation of UV-light, impel decomposition of initiator, produce free radical, cause resin reaction, instantaneous solidification film forming, is the paint of current environmental protection.
But existing UV paint also comes with some shortcomings: (1), traditional UV limit the use of in dull and stereotyped application, cannot use roller coating or showering for irregular coated article; As: the coated article of the three-dimensional arrangements such as chair must use spraying.(2), use spraying, but in the time that ultraviolet ray machine is dry, have " dead angle " according to less than UV-light, cannot make dried coating film.(3), dual dry UV sprays sub-light priming paint, except original UV-light is dry, separately has a kind of traditional drying mode.Although add isocyanate resin (iso cyanate) also to have dry effect in UV priming paint, have the restriction of " serviceable time (pot life) ".
Summary of the invention:
One of object of the present invention, is for the deficiencies in the prior art, and provides one not only can reach dual drying effect, does not also have the dual dry UV of the restriction of " serviceable time " to spray sub-light priming paint.
Object of the present invention two, be to provide described dual dry UV to spray the preparation method of sub-light priming paint.
The present invention is achieved by following technology:
A kind of dual dry UV sprays sub-light priming paint; Comprise the following raw material counting by weight percentage:
Preferably, the weight percent of described silicon class flow agent is 10%.
Preferably, the volume percent of described wetting agent is 10%.
Preferably, the volume percent of described nitro-cellulose solution is 30%.
Described dual dry UV sprays the preparation method of sub-light priming paint, comprises and is prepared as follows step:
(1), the configuration of work piece:
The preparation of silicon class flow agent: organosilicon and dimethylbenzene are fully uniformly mixed to 8～15 minutes, make described silicon class flow agent, described mixing speed is 500～800 revs/min;
The preparation of nitro-cellulose solution: 1/4 second Nitrocellulose and N-BUTYL ACETATE are uniformly mixed to 20～40 minutes, make described nitro-cellulose solution, described mixing speed is 800～1200 revs/min;
The preparation of wetting agent: polyethers one silicone copolymers and dimethylbenzene are fully uniformly mixed to 8～15 minutes, make described silicon class flow agent, described mixing speed is 500～800 revs/min;
(2), the configuration of main body coating:
First the mibk of described amount (MIAK), N-BUTYL ACETATE (BAC), 1-hydroxy-cyclohexyl phenyl ketone (184 light trigger), polyester acrylic resin, acrylic acid or the like flow agent, organosilicon flow agent, wetting agent, anti-yellowing change agent are put in reactor and stirred 15～30 minutes, mixing speed is 300～500 revs/min;
In reactor, add the epoxy acrylic resin of described amount, nitro-cellulose solution to stir 10～20 minutes again, mixing speed is 500～800 revs/min;
Finally in reactor, add talcum powder, EAC, silicon defoamer, the anti-settling agent stirring of described amount within 20～40 minutes, to make described dual dry UV and spray sub-light priming paint, mixing speed is 1000～1300 revs/min.
Preferably, in the preparation of described silicon class flow agent, calculating organosilicon according to weight percent is 10%, and dimethylbenzene is 90%.
Preferably, in the preparation of described Nitrocellulose, calculate according to volume percent, 1/4 second Nitrocellulose is 42.86%, N-BUTYL ACETATE is 57.24%.
Preferably, in the preparation of described Nitrocellulose, the solid content of 1/4 second Nitrocellulose is for admittedly containing 70%.
Preferably, in the preparation of described ground wetting agent, calculate according to volume percent, polyethers one silicone copolymers is 10%, dimethylbenzene is 90%.
The present invention includes: MIBK, BAC, 184 light triggers, polyester acrylic resin, acrylic acid or the like flow agent, silicon class flow agent, wetting agent, anti-yellowing change agent, epoxy acrylic resin, 30% nitro-cellulose solution, talcum powder, vinyl acetic monomer EAC, silicon defoamer, activation polyamide wax; Wherein EAC is that thinner reduces viscosity; 184 light triggers are the light trigger of Ciba.Epoxy acrylic resin of the present invention is matrix resin, and hardness of film is provided; Polyester acrylic resin is assisted resin, and snappiness is provided; Nitrocellulose (Nitr-ocellulose) (assisted resin mainly accelerates film surface drying speed film forming matter) is that the film that does not shine UV-light also can be dried; The agent of vinylformic acid levelling and organosilicon flow agent are promoted film flatness; Ground wetting agent is polyethers one silicone copolymers, promotes the wettability effect of coating to ground, and coating can be flowed in timber conduit; Talcum powder is #1200 order, increases fillibility and grinability; Anti-settling agent, for activation polyamide wax, prevents that talcum powder is firmly heavy; Anti-yellowing change agent, absorbs UV-light and still staggers with UV wave band peak, stops nitro-cotton to inhale composition and receives UV light xanthochromia.
The present invention uses nitro-cotton liquid collocation UV resin, not only can reach dual drying effect, also there is no the restriction of " serviceable time ".
