Abstract

The invention provides a nano-zirconia dispersion liquid, a preparation method thereof, a monomer dispersion liquid obtained based on the nano-zirconia dispersion liquid and an optical film, and belongs to the field of fine chemical engineering. The amount of nano-zirconia particles contained in the nano-zirconia dispersion liquid provided by the invention is 45 to 75 weight percent; through infrared spectrum characterization, it is found that functional groups in the following peak intervals are grafted on the surfaces of the nano zirconium oxide particles: a hydroxyl group with the peak interval of 3200 cm <-1 > to 3600 cm <-1 >, a Zr-O-Zr group with the peak interval of 480 cm <-1 > to 850 cm <-1 >, a saturated carbon-hydrogen bond with the peak interval of 2850 cm <-1 > to 2960 cm <-1 >, an ester carbonyl group with the peak interval of 1700 cm <-1 > to 1750 cm <-1 >, a delocalized conjugated ester group with the peak interval of 1460 cm <-1 > to 1580 cm <-1 >, a Si-O-Zr group with the peak interval of 800 cm <-1 > to 1200 cm <-1 > and a C-O ether bond with the peak interval of 1000 cm <-1 > to 1200 cm <-1 > the nano-zirconia dispersion liquid provided by the invention has high dispersion content, and the refractive index can reach 1.420-1.565; the dispersion content of the nano-zirconia monomer dispersion liquid obtained based on the nano-zirconia dispersion liquid can reach 55-85wt%, and the refractive index can reach 1.620-1.720; and the refractive index of a high-refractive coating can be greatly improved in subsequent preparation of a brightness enhancement film or an anti-reflection film, and therefore, the performance of the film is improved.

Description

technical field [0001] The invention belongs to the field of fine chemical industry, and in particular relates to a nano-zirconia dispersion liquid, a preparation method thereof, and the obtained monomer dispersion liquid and optical film. Background technique [0002] In recent years, through the combination of zirconia particle dispersion and transparent resin or film, it has been well used in the optical field by taking advantage of its high refractive index. For example, high-refractive zirconia dispersions are used to prepare optical films such as brightness-enhancing films and anti-reflection films, which can be used on LCD displays to increase the brightness and clarity of the screen; they can also be used to increase the refractive index of LED sealing resins, thereby improving LED performance. brightness. In a word, its high-refractive properties can be used in high-refractive coatings and applied in different fields. [0003] In the past, the above-mentioned zirc...
