preparation example Construction

[0061] Further preferably, the preparation method of the hydroxyl-terminated silicone oil of the present invention comprises: reacting the hydrogen-terminated silicone oil and alkenyl alcohol under a catalyst to obtain the hydroxyl-terminated silicone oil. More preferably, the reaction temperature of the present invention is 90-120°C, for example, 90°C, 95°C, 100°C, 105°C, 110°C, 115°C, 120°C. The reaction time of the hydroxy-terminated silicone oil can be determined according to the method of sodium hydroxide titration, and is not specifically limited. In one embodiment, the reaction time is 8 to 12 hours, for example, 8h, 9h, 10h, 11h , 12h.

[0062] The method of described sodium hydroxide titration is: get the mixture of terminal hydrogen silicone oil and alkenyl alcohol reaction under catalyzer, add in the acetone solution, titrate with 1N sodium hydroxide solution, when the reaction solution that takes out has no bubble (due to The silicon-hydrogen bond will react with ...

[0079] Embodiment 1 provides a kind of hydroxyl-terminated silicone oil

[0080] This embodiment provides a kind of hydroxyl-terminated silicone oil A 1 , its structural formula is as follows:

[0081]

[0082] x mean 18, y mean 22.

[0083] This example also provides the preparation method of the above hydroxyl-terminated silicone oil, including: in a 1L four-necked round bottom flask, add 550g of hydrogen-terminated silicone oil (x average value 18, y average value 22), heat up to 100 ° C, constant temperature 100 Add allyl alcohol (KarstedtPt catalyst 0.005g, allyl alcohol 12.54g) pre-mixed with KarstedtPt catalyst dropwise at ℃. After the addition is completed, the reaction solution is turbid. Continue to react at a constant temperature of 90°C for 3 hours, and the reaction solution gradually becomes clear. Transparent, get 5g of reaction solution in acetone solution, titrate with 1N sodium hydroxide solution, when the reaction solution taken out has no bubbles (due...

Abstract

The invention relates to synthesis of resins, in particular to a high-refractive-index resin, a preparation method and application thereof. The resin is prepared from hydroxyl-terminated silicone oil, alkyl alcohol hafnium and a hydroxyl compound. The invention provides a resin, which has a structure of organic hafnium, silicone oil and R2, can be endowed with high refractive index by modifying the silicone oil, especially the aryl-containing silicone oil, is used for preparing a transparent film with high refractive index, is expected to be used as a main component for preparing various materials with high refractive index, and is applied to various optical lenses, optical communication devices, optoelectronic devices, electronic display screens, LED light-emitting element packaging, OLED device refraction coefficient matching and other optical materials.

Description

technical field [0001] The present invention relates to the synthesis of resin, more specifically, the present invention relates to a kind of high refraction resin and its preparation method and application. Background technique [0002] With the development of science and technology, polymer optical materials are more and more widely used in materials such as optical discs, optical fibers, building materials, resin lenses, precision lenses and anti-reflection coatings. High refractive index optical resin is an important research direction of optical materials, which can further reduce the curvature and thickness of components, reduce weight without affecting its refractive ability, and make optical instruments miniaturized and lightweight. [0003] When the high-refractive index coating is coated on the surface of high-refractive-index optical resin, it can make up for its various shortcomings such as wear resistance, solvent resistance, and poor moisture absorption resista...
