Description
Technical field
The present invention relates to a kind of coating, particularly a kind of Thick film type polyurethane finish paint.
Background technology
The coating of carbamate chain link (-NH-CO-O-) containing some amount in filming polymer structure is referred to as its normally isocyanate group and hydroxy-containing compounds reaction and obtain of polyurethane coating, and reaction formula is as follows:
R-N=C=O+R′-OH→R-NH-CO-OR′
Except containing except amino-formate bond in polyurethane coating film, also containing many ester bonds or unsaturated double-bond, tricarbimide ester bond, urea key, allophanic acid ester bond, ehter bond etc.
Therefore, this coating property is abundant, excellent:
1. there is a large amount of hydrogen bonds in paint film, therefore, paint film is firm, wear-resisting, bright, plentiful, sticking power is good.
2. by regulating section chain length, distribution and cross-linking density, obtaining the film of required mechanical property, having from hard film to extremely soft elasticity film, to adapt to the needs of varying environment.
3. excellent, acidproof, the water resistance of antiseptic property is better than epoxy coating, acid-and base-resisting, water, and resistance toheat is better than vinyl resins paint.
4. ambient temperature curable, also heating curable, even if also can drying and forming-film below 0 DEG C, therefore construction and operating restraint wide.
Due to existing polyurethane finish one-pass film-forming thinner thickness, usually at about 25 μm, therefore, obtain thicker build must through repeatedly brushing, therefore time-consuming, and heavy antisepsis engineering exactly needs is exactly thick film.The invention provides a kind of Thick film type polyurethane finish paint, can one-pass film-forming, build 50-60 μm, thus the object reaching saving of work and time.
Summary of the invention
Object of the present invention is just to overcome above-mentioned the deficiencies in the prior art, and provides a kind of low solvent, pollutes the little and good Thick film type polyurethane finish paint of water tolerance, chemical resistant properties and weathering resistance.
Technical scheme of the present invention is, Synolac 40-50 part, Hydroxylated acrylic resin 20-30 part, titanium dioxide 15-35 part, defoamer 0.1-0.8 part, dispersion agent 0.2-1.0 part, flow agent 0.1-0.8 part, auxiliary rheological agents 10-30 part, organobentonite 2-10 part, and thinner, add solidifying agent by proportioning during molding in finish paint, solidifying agent used is aliphatic polymeric isocyanate, and its usage quantity is the 25%-30% of Synolac and Hydroxylated acrylic resin weight sum.
Further, be made up according to following weight proportion of following raw materials according: Synolac 42-47 part, Hydroxylated acrylic resin 23-28 part, titanium dioxide 20-30 part, defoamer 0.2-0.5 part, dispersion agent 0.4-0.7 part, flow agent 0.2-0.5 part, auxiliary rheological agents 15-25 part, organobentonite 3-7 part, and thinner, add solidifying agent by proportioning during molding in finish paint, solidifying agent used is aliphatic polymeric isocyanate, and its usage quantity is the 25%-30% of Synolac and Hydroxylated acrylic resin weight sum.
Further, described thinner is made up according to following weight proportion of following raw materials according: butyl ester 10-20 part, dimethylbenzene 5-15 part.
Further, the preparation method of described a kind of Thick film type polyurethane finish paint paint vehicle, preparation method of the present invention is: first add Synolac, then titanium dioxide, organobentonite, auxiliary rheological agents, dimethylbenzene, butyl ester, dispersion agent is added in order, disperse with high speed dispersor, grind after being uniformly dispersed, grinding is stopped to enter into paint operation when being ground to fineness 20 μm, add Hydroxylated acrylic resin, flow agent, defoamer successively, carry out high speed dispersion again, after being uniformly dispersed, after factory inspection is qualified, be carried out in accordance with regulations packaging.
The raw material used in the present invention all can be bought from market and obtain:
Synolac is the grand 1300F resin of state, Hydroxylated acrylic resin is modest 3060 resins of moral, aliphatic polymeric isocyanate is BASF HB175 resin, titanium dioxide is one hundred profit connection titanium dioxide, the mixture of dispersion agent to be the safe 904s main component of the rising sun be polymeric carboxylic and modified polyorganosiloxane, flow agent is safe 432 main components of the rising sun is modified polyorganosiloxane, defoamer is safe 6500 main components of the rising sun is modified polyorganosiloxane, auxiliary rheological agents is modest 229 main components of moral is polyamide wax, and butyl ester, dimethylbenzene and organobentonite can grand from state, preciously respectively to overflow and three fish companies buy.
The grand GL1300F resin of selected state has higher solids content (80%), viscosity lower 15 ~ 26S(form pipe), tool color inhibition, of light color, select moral modest resin 3060 resin, this resin viscosity is low simultaneously, admittedly containing 60%, have the performance of acrylic paint, we also have selected the modest board polyamide wax of the good moral of thixotropy, three fish board organobentonites simultaneously, carry out sag prevention process, by repetition test, effectively complete the screening of formula, make it the target reaching more than one-pass film-forming 50um.
The present invention has following advantage and positively effect:
1. during spraying, dry film scope is 50-60 μm, thus 3 ~ 4 traditional road coating procedure can be made to be reduced to 2 ~ 3 road coating procedure, simplifies painting design, shortens the engineering time, accelerate application speed, also adds the efficiency that improve structure steel fabrication simultaneously.
2., because solvent in paint is few, reduce the pollution to environment.
3. the Thick film type polyurethane finish paint made according to combination formula of the present invention all has very strong sticking power to various base material, and the hardness of coating is high, has good water tolerance, weathering resistance and chemical resistant properties.
