Description
Technical field
The invention belongs to chemical coating field, be specifically related to a kind of spectacle-frame coating and preparation method thereof.
Background technology
Further investigation reveals that, China suffers from total crowd of distant vision defect in various degree and reaches 3.45 hundred million-3.51 hundred million, and prevalence is up to 27.8%-28.27%, and wherein, the distant vision defect of more than 98% belongs to light moderate visual impairment. Total number of patients of China's myopia population is between 4.37-4.87 hundred million. Development along with society; the rhythm of life of people is more and more faster; life stress is increasing; cause people's extended sleep deficiency, excess eye-using; simultaneously also because people need for a long time in the face of electronic product works and lacks the reasons such as eye protection consciousness, the crowd of wearing spectacles is in the trend constantly risen.
Along with the raising of people's living standard, people are to the performance of glasses and attractive in appearance have higher requirement. Coating refers to a kind of general name of material of continuous protective film being coated in body surface and forming firm attachment, plays decoration and defencive function. People, in order to improve practicality and the aesthetic property of glasses, are typically in outside eyeglass or picture frame and are coated with a coating to improve its effect practical and attractive in appearance. Chinese patent application 201410337352.6 discloses a kind of optical glass coating, described optical glass coating is made up of ��-glycidylpropyl trimethoxy silane, stannum oxide, polysiloxane surfactant, isopropanol, ethyl cellosolve, aluminium acetylacetonate and hydrochloric acid, the coating prepared has adhesive force and the transparency of excellence, also there is excellent resistance to impact, scratch resistance and resistance to water, it is possible to the effective definition improving eyeglass and ruggedness.
At present, the spectacle-frame coating that people use can also effectively improve absorption of perspiration and the corrosion resistance of spectacle-frame, greatly extends the service life of spectacle-frame. But currently used spectacle-frame coating depends on Italy and Germany's import, expensive, greatly limits it and produces and application.
Chinese patent application 201110374315.9 discloses a kind of spectacle-frame coating and preparation method thereof, and described spectacle-frame coating is made up of organobentonite, ink zinc stearate, colour carbon black, auxiliary agent FX540 and Hydroxylated acrylic resin. The glasses coating prepared has excellent heat-resisting and lower temperature resistance, also has advantage nontoxic, that safety is high simultaneously.But, this spectacle-frame coating hardness is relatively low, and pliability is poor, sweat proof performance is low, and long periods of wear is coated with the picture frame of above-mentioned coating easily to be occurred tarnishing or the phenomenon of pull-away, has a strong impact on the aesthetic property of spectacle-frame.
Therefore, research and develop out that a kind of price is low, hardness and richness is high, flexibility and the good spectacle-frame coating of sweat proof performance are still the emphasis of current research.
Summary of the invention
