Description
Technical field
The present invention relates to a kind of metope anti-stick coating, in particular, the present invention relates generally to the anti-doodling paint that the micro-rough structure of fluorine silicon resin modification is worked in coordination with in a kind of photochemical catalysis.
Background technology
Scribble infringement is large public hazards of mankind's modern civilization always, and it makes object plane be stained with image or the word of harmful view, not only destroys the attractive in appearance of city appearance, even destroy its structure.Tackling effective means the most of scribbling is adopt anti-doodling paint, especially most popular with permanent anti-doodling paint, and need its aspect hard and wear-resisting, scribble is difficult to stain on it, or easy-clear.Existing coating majority requires some distance with desirable anti-doodling paint.In existing anti-doodling paint, what determine its salient features is adopted resin, it is local in order to can be widely used in each, need the resin material selecting to ensure serviceability under different envrionment temperatures, in thermal adaptability, silicone resin has huge advantage, and cheap, other function ingredients synergy can be merged after modification.
Silicone resin with silicon-oxygen (Si-O) key for backbone structure, general organic resin is based on C-C key, the latter's key is by force not as the former, so the thermostability of silicone resin is high, under high temperature, the chemical bond of (or radiation irradiation) molecule does not rupture, does not decompose, experiment proves silicone resin 250 DEG C of heating after 24 hours, and silicone resin weightlessness is only 2-8%.Silicone resin not only can be high temperature resistant, and low temperature resistant, and can use in a very wide temperature range, no matter be chemical property or physical and mechanical properties, variation with temperature is all very little.At present, the more organic silicon antifouling paint of market-oriented application and research all has low surface energy, is mainly polydimethylsiloxane (PDMS) polycondensation system crosslinked with tetraethoxy (TEOS).But class low surface energy organic silicon coating does not obtain production application widely, mainly lock into the deficiency of the following aspects: one is the poor adhesive force with base material, recoatability is poor, usual needs apply special organosilicon and connect paint between epoxy primer and low surface energy organic silicon coating, application matching system is complicated, not easily constructs; Two is that intensity is not high, fragile, easily damaged through repeatedly washing away caudacoria surface, can not occur rubbing with scleroid material;
Those skilled in the art make great efforts to have made certain improvement for above-mentioned deficiency, but there is new limitation, such as publication number is non-viscous paint and the coating method thereof that the Chinese invention patent of CN103205203 discloses a kind of nanosized SiO_2 hydridization polyester resin change properties of organic silicon, it uses nanosized SiO_2 hybridized polyester-modified organic silicon resin, epoxy resin, melamine resin, filler, organic solvent, not sticky auxiliary agent, macromolecule dispersing agent, adhesion promoter synthesizes, wherein nanosized SiO_2 hybridized polyester-modified organic silicon resin forms with MeSi (OH) 3 condensation, to improve the application of organosilicon on metal material, but this kind of non-adhesive material in use needs the product after by spraying to carry out sintering at the temperature of 270-290 DEG C could form last film finished product.This Temperature Treatment will cause the distortion of the substrate of metal sheet or plastic material, is also unfavorable for being applied in outdoor public; In other words, though technical scheme has certain modification to organosilicon disclosed in this patent, but still need pyroprocessing, thus still there is above-mentioned deficiency.And traditional anti-graffiti material is only paid attention to material and is resisted the performance that ink and pigment infiltrates, coating does not have the capacity of decomposition to pigment and specific adhesive, thus the inadherent performance of metope is limited all the time, therefore need be non-caked and prevent the coated material of scribbling from doing further research and improving to metope.
Summary of the invention
