Description
Technical field:
The present invention relates to technical field of coatings, relate in particular to a kind of streamline stereoeffect application polyurethane transparent priming paint and preparation method thereof.
Background technology:
What the streamline application was generally used at present is nitrocellulose (NC) coating, because of its quick-drying, and it is transparent preferably, product stereoeffect after the application is splendid, be particularly suitable for pipelining, but because environmental protection aspect factor, country has begun to limit gradually the use of nitrocellulose (NC) coating.And at present on the market common urethane (PU) coating can't satisfy the requirement of streamline stereoeffect application.
Summary of the invention:
One of purpose of the present invention, be at the deficiencies in the prior art, and a kind of painting effect that namely can reach NC coating and rate of drying, can the polishing time short be provided, have the feature of environmental protection of conventional polyurethanes coating and the streamline stereoeffect application polyurethane transparent priming paint of excellent physico-chemical property simultaneously again.
Purpose of the present invention two, be to provide the described streamline stereoeffect application preparation method with polyurethane transparent priming paint.
The present invention is achieved by following technology:
A kind of streamline stereoeffect application polyurethane transparent priming paint; Comprise first component, second component and thinner, the weight proportion of described first component and second group is 4: 1,

N-BUTYL ACETATE (BAC) 85%～95%
1-Methoxy-2-propyl acetate 5%～15%.
Wherein, the solid content of described first component is 46%～54%, and the solid content of described component B is 40%～45%; The cellulose nitrate cellulose solution is that volumetric concentration is 30% cellulose nitrate cellulose solution.
The preparation method of described polyurethane transparent priming paint comprises being prepared as follows step:
(1), the preparation of first component:
A, the modification quick-drying ricinoleyl alcohol acid resin with described amount, cellulose nitrate cellulose solution, dispersion agent and N-BUTYL ACETATE mixed 8～15 minutes after dropping into reactor, and described mixing speed is 800～1200 rev/mins;
B, again with the polishing agent stearic acid zinc powder of described amount, the pigment extender talcum powder slowly drops in the reactor, mixes 20～40 minutes, described mixing speed is 800～1200 rev/mins;
C, add defoamer, flow agent, the anti-settling agent of described amount and mixing 10～30 minutes at last, described mixing speed is 600～1000 rev/mins;
D, more than make product and get the sample test back packing of filming, make described first component;
(2), the preparation of component B:
A, the TDI tripolymer with described amount, TDI affixture, HDI tripolymer, N-BUTYL ACETATE are put in second reactor, mix 5～15 minutes, and described mixing speed is 50～200 rev/mins;
B, above mixture are weighed on request, are packaged to be described component B.
During concrete the use, be in harmonious proportion with thinner.
Preferably, described dispersion agent is the carboxylic acid acid ester solution with hydroxyl-functional of pigment affinity groups; Preferred BYK 107.It improves pigment wetting in coating, shorten the process of lapping required time, and make colo(u)rant dispersion stable, improve gloss and levelling and prevented loose colour/grow dim, this auxiliary agent has reduced viscosity and has avoided thixotropy, often pigment extender content can increase but without detriment to gloss, and mill base viscosity sharply descends, and has preferably the color acceptability and can not demonstrate loose colour and grow dim when mixing colours with universal stains.
Preferably, described defoamer is the modified polyorganosiloxane defoamer, preferred moral modest 6500.
Preferably, described anti-settling agent is the poly-sour amide waxe of activation, preferred Supreme Being Si Balong 6900.It has anti-vertical, the anti-heavy character of powerful persistence.Can or seldom not separate out, glossiness and weathering resistance are influenced seldom; Appoint use-pattern all can bring into play the optimum dispersion effect.Need not accurately to control temperature and precast gel liquid, in wet film, for improvement of the coordination (orientation) of metallic pigment.
Preferably, described flow agent is the organosilicon flow agent, preferred BYK300.
Preferably, the preferred Zinic stearas of described polishing agent.
Preferably, the preferred SAPICI 141 of described modification quick-drying ricinoleyl alcohol acid resin.
Preferably, the preferred Mitsui Chemicals D-262 of described TDI tripolymer, the preferred BAYER 2605 of TDI affixture, the preferred BAYER N3390 of HDI tripolymer.
The present invention includes first component and second component, the weight proportion of described first component and second group is 4: 1, and described first component comprises modification quick-drying ricinoleyl alcohol acid resin, cellulose nitrate cellulose solution, dispersion agent, defoamer, anti-settling agent, pigment extender, polishing agent, flow agent, solvent; The second component comprises, TDI tripolymer, TDI affixture, HDI tripolymer, N-BUTYL ACETATE.And comprise TDI tripolymer, TDI affixture, HDI tripolymer, N-BUTYL ACETATE.First and second components are passed through respectively to mix, high speed dispersion, and product examine is filtered, and packing prepares and gets.
Ultimate principle of the present invention is to satisfy the streamline stereoeffect by the rate of drying that promotes polyurethane coating and stereoeffect to be coated with reload request.Urethane (PU) coating mainly reacts to realize dry by polyol component and polyisocyanate component, because the restriction of present state of the art, its rate of drying and stereoeffect can't be taken into account.And the present invention both can reach painting effect and the rate of drying of NC coating, can lack the polishing time, had the feature of environmental protection and the excellent physico-chemical property of conventional polyurethanes coating simultaneously again, had wide application space.
The present invention is by carrying out the strictness screening to starting material, selected the to be exceedingly fast ricinoleyl alcohol acid resin of dried, high tenacity, high transparent, be aided with a small amount of nitrocellulose simultaneously and do modification, the collocation polyisocyanate mixtures dried, high tenacity that is exceedingly fast has satisfied streamline stereoeffect clear finish and has been coated with reload request.
