Embodiment 1

[0045] Preparation of amine compounds:

[0046] Halogenation reaction---Dissolve 5g of dipentaerythritol (Bailingwei) in a flask filled with 100ml of ethanol, add 5.06g of halogenating agent NaBr (Alfa Aesar) dropwise into the flask in an oil bath at 25°C, and put the oil bath The temperature was raised to 170°C, and at the same time, the stirring was started, and after stirring for 20 hours, the product was obtained by rotary evaporation and drying;

[0047] Ammonolysis reaction---Dissolve the obtained 6.2g product (0.012mol) in a flask filled with 100ml methanol and 0.5g ammonium chloride (Hunan Jianghe Environmental Protection Industry), and add 25wt% concentration of chloroformate in three times under the protection of nitrogen atmosphere. A total of 14.5 g (0.104 mol) of ammonia water was raised to 150°C and stirred for 24 hours. After extracting, rectifying and drying, the final amine compounds are obtained.

Embodiment 2

[0051] Preparation of optical resin materials:

[0052] Take 11g of isophorone diisocyanate, 15g of dicyclohexylmethane diisocyanate, add 0.75g of the amine compound prepared in Example 1 and 0.02g of catalyst triethylenediamine (Hubei Chushengwei Chemical Industry Co., Ltd.) , 0.015g internal release agent di-n-butyl phosphate (Hangzhou Dayang Chemical Industry) and 0.025g ultraviolet absorber 2-(2H-benzotriazol-2-yl)-4-methylphenol (Hubei Guangao Biotechnology ), fully dissolved to obtain solution A. Weigh 5 g of bis(mercaptoethyl) sulfide (Bainwei) and 15.4 g of pentaerythritol tetrakis(3-mercaptopropionate) (Jingbo) and mix them uniformly to obtain component B. The two components A and B are mixed at 25°C, and the uniformly mixed liquid is defoamed at 600Pa for half an hour, and then filtered through a 1μm PTFE filter. The filtered combination liquid is poured into the mold, heated from 25°C to 115°C for 16 hours to heat and solidify, and finally the product is obtained ...

Abstract

The present invention provides an optical resin composition, an optical resin material and applications thereof. The optical resin composition includes: (a) a polyisocyanate compound, (b) a polythiol compound, and (c) an amine compound; wherein, The polythiol compound includes pentaerythritol mercapto carboxylate and other polythiol compounds, and the other polythiol compounds contain more than two mercapto groups; the amine compound is obtained by ammonolysis of the halide of pentyl polyol . Using the composition to prepare optical resin materials has good impact resistance, excellent optical properties and moderate refractive index, and is especially suitable for preparing optical lenses and optical devices; meanwhile, the composition has the characteristics of easy-to-obtain raw materials.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an optical resin composition, an optical resin material prepared therefrom and applications thereof. Background technique [0002] Resin lenses have greater advantages over ordinary inorganic lenses in terms of density, refractive index, processability, dyeability, etc., so they have been widely used and are likely to replace inorganic lenses. Common resin lenses mainly include four types, namely: acryl diglycol carbonate (CR-39), polymethyl methacrylate (PMMA), polycarbonate (PC) and polythiourethane class (PU). CR-39 has the advantages of easy dyeing, impact resistance, and good chemical stability, but its low refractive index makes the prepared lenses thicker, which is not suitable for the preparation of high-number lenses; PMMA lenses are light in weight, cheap and easy to process, but easy to process. It is deformed by heat and has poor wear resistance; PC lenses are rigid a...
