Description
Technical field
The present invention relates to glasses manufacturing fields, and in particular to a kind of ophthalmic len superhard coating.
Background technology
Resin lens are a kind of organic materials, and inside is a kind of macromolecule chain structure, connection and spatially net structure,
Intermolecular structure relative relaxation, molecule interchain have the space that can generate relative displacement.Light-transmissive rate is 84%-90%, thoroughly
Photosensitiveness is good, while optical resin lens anti-impact force is strong.
Existing ophthalmic len generally all selects resin lens, and existing resin lens generally select aluminium oxide or titanium dioxide
Silicon coating, but the hardness of these coatings is general, and under extreme conditions, the minute surface of the coating still can damage.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of glasses of new structure
Piece superhard coating makes it with more the utility value in industry.
The content of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of ophthalmic len superhard coatings.
Technical scheme is as follows：
A kind of ophthalmic len superhard coating, which is characterized in that in parts by weight, including：
Further, a kind of preparation method of ophthalmic len superhard coating, which is characterized in that including following steps：
S1, alumina powder is ground to nanoscale by super grinder；
S2, alumina powder is added in glass ionomer, it is stirred by ultrasonic stirrer；
S3, glass ionomer is irradiated with ultraviolet light, irradiation time is specially 0.5 second, makes glass ionomer material
Expect surface semi-solid preparation, then it is stirred by mixer；
S4, stirring simultaneously mix tetrem and support base silane, ethylene glycol and glacial acetic acid；
S5, step S3 products and step S4 products are mixed, and passes through infrared heater and be warming up to 80-90 DEG C；
S6, S5 products are cooled to room temperature, are ejected by jet blower on ophthalmic len and form coating, and shone by ultraviolet light
Penetrate coating 8-10 seconds.
Further, a kind of preparation method of ophthalmic len superhard coating, it is characterised in that：In the step S5, the painting
The thickness of layer is 200-300nm.
According to the above aspect of the present invention, the present invention has at least the following advantages：
(1) by adding glass ionomer in inventive formulation, the scratch resistant performance of entire coating can be improved；
(2) present invention is irradiated in preparation process using ultraviolet light twice, while by glass ion water during irradiation for the first time
Door spit of fland semi-solid preparation, first, can cure a part of glass ionomer in preparation process, increases each material in mixed process
Structural capacity, second is that mitigate the later stage injection after curing of coatings time.
Above description is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and be described in detail as after.
