The invention also discloses an application method of the dyeing liquid for the optical resin. Compared with the prior art, the dyeing liquid for the optical resin is simultaneously applicable to polar and nonpolar optical resins and has good dyeing effect.
Description
Technical Field
The invention relates to the technical field of dye compositions, in particular to a dye solution for optical resin and an application method thereof.
Background
Compared with optical glass, optical resins are light in weight, excellent in processability and strong in impact resistance, and have gradually become preferable materials for optical application fields. Conventionally, there are optical resin materials such as polymethyl methacrylate type, polystyrene type, polycarbonate type, poly 4-methylpentene type, poly allyl diglycol carbonate type, polyethylene terephthalate type, polyether sulfone type, polyurethane type, polyolefin type, styrene- (meth) acrylate copolymer type, styrene-acrylonitrile copolymer type, epoxy resin type, or a combination of the above types, and the like, and they can be processed into lenses (for example, spectacle lenses, goggle lenses, camera lenses, microscope lenses, projector lenses, lenses for sports, lenses for laser scanning, lenses for optical disk pickup, magnifier and the like), windshields, polarizing plates, polarizing films, indoor light-reflecting films, optical cards, grating disks, optical filter elements, liquid crystal display elements, optical waveguide elements and the like.
When the optical resin product or the particle is applied to certain fields, the optical resin needs to be dyed in order to enhance fashion and aesthetic properties, or in order to reduce light transmittance, or in order to reduce glare, or in order to obtain a masterbatch with resin as a matrix. As a representative of the dyeing method, the direct dip dyeing method of disperse dye has low cost, high efficiency, little harm to the environment and human body and the most wide application. Common disperse dyes are azo, anthraquinone and quinione, wherein the disperse dyes contain a certain amount of polar groups, and polar products are easy to color. For example, in the invention patent with patent application number of CN201510103093.5 (publication number of CN 104650621A), namely, a disperse dye composition, a disperse dye, a preparation method and application thereof, a polyester, polyester cotton or polyester ammonia and other polar fabrics are directly immersed in a dyeing liquid containing water, an auxiliary agent and a compound disperse dye, so that textiles with excellent fastness are obtained; the invention patent with the application number of CN201310487988.4 (publication number of CN 103590129A) discloses that the non-polar products such as polypropylene fibers are difficult to dye, and the polarity of the surfaces of the fibers can be enhanced by a surface treatment method, a copolymerization method, a dyeing seat method and the like, so that the dyeing effect of disperse dyes on the non-polar products is promoted.
The optical resins have higher dyeing requirements (e.g., smoothness, deformation rate, transparency, etc.) than those of bulk articles such as textiles, leather, paper, and household goods. With the expansion of the application range of optical resins, research and realization of high quality dyeing of optical resins have great commercial value. For example, the invention patent with the application number of CN99815817.8 (publication number of CN 1333795A) is to dip-dye the spectacle lens and the sunglass lens in disperse dye solution to obtain red, yellow, orange, blue, purple and brown lenses; the invention patent of patent application number CN03108353.6 (publication number CN 1276274C) is a dyeing method of thermoplastic resin plastic lens and a colored plastic lens obtained by the method, wherein additives such as single ring and single paste are added into disperse dye liquor, red, yellow, blue, orange and purple optical resin lenses are obtained under the condition of low temperature and short time, and gradient coloring of the lenses is realized by controlling the dyeing time of different positions of the lenses; patent WO0014325 obtains red, yellow and blue lens articles by means of microwave radiation when resin lenses are impregnated with a disperse dye.
However, black is a preferred color for optical resin articles requiring high light absorption capacity. Unfortunately, there has been no report of blackening the optical resin, and dyeing of a nonpolar optical resin has been more difficult and more challenging.
