Prepare middle temperature baking type fluorine-carbon paint of the present invention, in the selected component, fluoro-resin is to be main raw material with the tetrafluoroethylene, has low-temperature bake fluorine carbon lacquer unexistent " no chlorine " feature in other trifluoros systems, can form the tough of richer weather resistance, weathering resistance and film.Aminoresin and CAB551-0.2 have good weather, with the fluorocarbon baking varnish paint film cross-linking density height of tetrafluoro resin collocation preparation.Wherein, aminoresin is hexakis-methoxy methyl melamine resin, has good compatibility, and simultaneously because its functionality is 6, cross-linking reaction degree height, paint film have shock resistance, excellent flexibility and the anti-various chemical mediator of high rigidity, excellence.CAB551-0.2 can have compatibility preferably with the fluoro-resin in the component, its adding has not only improved the physical and mechanical properties of filming, as shock resistance and snappiness, the more important thing is that it makes paint film have good recoatability, need not carry out surface treatment can levelling freely, ply adhesion reaches 1 grade, and existing general fluoro-resin-aminoresin system recoatability is poor, as coating surface not being carried out grinding process, then recoat time lacquer liquid can't wetting coating surface, and lacquer liquid can't levelling.In addition, the CAB551-0.2 adding also helps the solvent snap-out release, impels paint film rapid drying.Described acid catalyst has the effect that reduces storing temperature and shorten storing time to the hexakis-methoxy methyl melamine resin system of low reactivity.Especially further adopting the solution of tosic acid amine salt as acid catalyst in the technical scheme, than pure tosic acid, its influence to viscosity between the shelf lives obviously reduces, the 1.5-3 that can extend shelf life doubly reduces 10-20 ℃ of storing temperature than other dead front type Catalyzed by p-Toluenesulfonic Acid agent (as sealing with morpholine or amino methyl propyl alcohol) tolerable.
Temperature baking type fluorine-carbon paint in of the present invention has following advantage:
1. temperature baking in only needing is enhanced productivity, and significantly cuts down the consumption of energy.
2. have the weathering resistance above PVDF type fluorine carbon lacquer, filming of formation can keep beautiful application outward appearance for a long time, even also show outstanding weathering resistance under harsh environment.
3. the hardness height still has excellent shock resistance and resistance to bend(ing) behind wear resistance, shock resistance, resistance to bend(ing) excellence, the especially recoat.
4. resistance to crocking excellence.
5. all fast light 8 grades, weather-proof 5 grades and heat-resisting various pigment more than 180 ℃ all can be used for of the present invention in temperature baking type fluorine-carbon paint, comparing PVDF type fluorine carbon lacquer needs to cause dull coloring at high bake more than 230 ℃, fluorine carbon lacquer color selectivity of the present invention is widened greatly, and rich color is colorful.
6. solvent discharges soon, and paint film rapid drying has good workability, and does not need to do any particular processing during recoat, and normal position does not need polishing, ply adhesion excellence.
Temperature baking type fluorine-carbon paint in of the present invention can be applicable to aluminium sheet, steel plate galvanized and general steel plate.
