A kind of environmental protection coating material that can lift spectacle-frame comfort level and preparation method thereof
Technical field
The present invention relates to chemistry painting industry field, specifically a kind of environmental protection coating material that can lift spectacle-frame comfort level and its preparation
Method.
Background technology
At present, crowd quantity more and more higher of the China with different degrees of distant vision defect, wherein, more than 98% hypermetropia
Power defect belongs to light moderate visual impairment.And as the development of society, the rhythm of life of people are more and more faster, life stress is more next
It is bigger, cause people's extended sleep deficiency, excess eye-using, while also because people need to be worked and be lacked in the face of electronic product for a long time
The reasons such as few eye protection consciousness, the crowd of wearing spectacles is in the trend for constantly rising.
With the improvement of people's living standards, people are to the performance of glasses and attractive in appearance put forward higher requirement.In order to carry
The practicality and aesthetic property of high glasses, typically applies a coating to improve its practical and attractive in appearance effect outside eyeglass or picture frame.
At present, the spectacle-frame coating that people use can also effectively improve the absorption of perspiration and corrosion resistance of spectacle-frame, greatly prolong eye
The service life of picture frame.But the spectacle-frame coating for using at present depends on Italy and German import, expensive, greatly
Big limits its production and application.
Number of patent application discloses a kind of spectacle-frame coating and preparation method thereof for 201110374315.9, and the coating is by having
Machine bentonite, ink zinc stearate, colour carbon black, auxiliary agent FX540 and light base acrylic resin composition.The glasses for preparing
Coating has excellent heat-resisting and lower temperature resistance, while also having the advantages that nontoxic, safe.But, the spectacle-frame coating
Hardness is relatively low, and pliability is poor, sweat proof performance is low, long periods of wear be coated with the picture frame of above-mentioned coating easily occur tarnishing or
The phenomenon of pull-away, has a strong impact on the aesthetic property of spectacle-frame.
Therefore, research and develop out a kind of low price, the spectacle-frame that hardness and richness are high, flexibility and sweat proof performance are good
Coating is still the emphasis of current research.
