Therefore, the objective of the invention is, overcome the complex manufacturing technology of tapetum lucidum material cost height, character and/or pattern and can not on complex-shaped surface, make character and/or the shortcoming of pattern (especially complicated cover colored pattern), provide a kind of and not only can on flat surfaces, make regression reflecting character and/or pattern, but also can on complex-shaped surface, make the coating composition of regression reflecting character and/or pattern (especially complicated cover colored pattern).
Above-mentioned purpose of the present invention realizes by a kind of coating composition is provided, this coating composition contains membrane-forming agent, pigment and solvent, it is characterized in that, be as the criterion in its gross weight, described coating composition contains that 20~75% (weight) transparency is 25~95%, specific refractory power is 1.4~1.6 membrane-forming agent, 5~50% (weight) reflectivity is 30~90% pigment, and 20~60% (weight) paint solvent.
In coating composition of the present invention, every transparency be 25~95% and refractive index n be that 1.4~1.6 membrane-forming agent all can use, its consumption is 20~75% of a described coating composition gross weight.The membrane-forming agent example that is suitable for has Nitrocellulose, acrylic resin, urethane resin, resol, Resins, epoxy, and comprises one or more membrane-forming agents in the various synthetic rubber of chlorinated rubber, chloroprene rubber and styrene-butadiene rubber(SBR).In the above under the transparency of defined and the specific refractory power prerequisite, can be according to factors such as acid resistance, alkali resistance, weathering resistance and wear resistance are chosen to film.
As for pigment, coating composition of the present invention must adopt the pigment of reflectivity in 30~90% scopes, and its consumption is 5~50% of a described coating composition gross weight.Specifically, can adopt white pigment, for example titanium dioxide; Also can adopt the inorganic mineral pigments that comprises mica, quartz and silica; Also can adopt red, yellow, blue, green, silvery white, golden yellow etc. except that black, comprise the organic or inorganic coloured pigment of various secondary colors, intermediate color.The example of other suitable pigments has the subparticle of metals such as various spirit soluble dyestuffss, most inorganic pearly pigment, organic pearly pigment and metallic pigment such as copper, aluminium, silver, gold, titanium, nickel, chromium.In order to obtain various intermediate colors or secondary color, can use the different ratios mixture of above-mentioned various pigment.
In coating composition of the present invention, used solvent is conventional paint solvent.It accounts for 20~60% in the gross weight of coating composition of the present invention.The example of suitable solvents has toluene, dimethylbenzene, ethyl acetate, pimelinketone, and the mixture of 120~No. 200 industrial napthas or one or more above-mentioned solvents.
In order to make some membrane-forming agent quicken to solidify, coating composition of the present invention also can contain coupling agent commonly used, for example plumbous manganese cobalt coupling agent.Its content is 0.5~10% of coating composition gross weight of the present invention.
With the matching used glass microballon of coating composition of the present invention, its specific refractory power is 1.5-2.3, and granularity is 20-500 μ m.
According to a further aspect in the invention, the present invention also provides a kind of regression reflecting coating of making of coating composition of the present invention and glass microballon, it is characterized in that, described glass microballon is by adhesion and be embedded in the top layer that coating composition of the present invention applies paint film that the back becomes, the specific refractory power of the described glass microballon that is used is 1.5~2.3, and its granularity is 20~500 μ m, and the reflection coefficient of manufactured coating is in 5~180 scopes.Be in for the reflection coefficient that guarantees regression reflecting coating of the present invention near the upper limit end of above-mentioned scope, preferably glass microballon is carried out the local surfaces metalized, for example vacuum aluminum-coated processing, so that form reflectivity up to 90~96% on the glass microballon hemisphere face, thereby the R value that can make made regression reflecting coating is within 100~180 scope.
According to another aspect of the invention, coating composition of the present invention cooperates glass microballon to make the high regression reflecting coating of reflection coefficient R value, provide at swiftly passing object, for example made the application of enlarged character and/or pattern and so on regression reflecting sign on Motor vehicles and the boats and ships.In addition, again owing to can make various complicated chromatography regression reflecting pattern and/or characters, so coating composition of the present invention and regression reflecting coating of the present invention also provide in the application of making aspect various bright-coloured, eye-catching insignia, service mark and the advertisement picture and text by the present invention.
Because coating composition provided by the present invention can optically mate with glass microballon well, the possibility of making the regression reflecting coating of reflection coefficient R value in 5~180 scopes is provided, so the present invention has overcome tapetum lucidum material cost height in the prior art, the complex manufacturing technology of character and/or pattern and the shortcoming that can not on complex-shaped surface, make character and/or pattern (especially complicated cover colored pattern), provide a kind of even can on complex-shaped surface, make the high regression reflecting coating of reflection coefficient R value with low cost and easy manufacture craft, thereby can be at swiftly passing object, Motor vehicles for example, make enlarged character and/or pattern and so on regression reflecting sign on the boats and ships, the effect suitable with the traffic safety performance to traffic administration.In addition, owing to can make various character and/or patterns with regression reflecting performance by the present invention, especially complicated chromatography regression reflecting pattern, so coating composition provided by the invention also can be used for making various bright-coloured, eye-catching insignias, service mark and advertisement picture and text, self-evident, coating composition of the present invention application in these areas is with the looks in take on a new look greatly city and small towns.
Come sets forth in detail the present invention with some embodiment below, but these embodiment are used for limiting protection scope of the present invention by no means.
