Embodiment

[0019] A preparation method of trisphenol A type cyanate, in a 3000ml four-necked flask equipped with a stirrer, dropping funnel and thermometer, first put 2600g of ether into it, cool to -5°C, and then add 400g of cyanogen chloride.

[0020] Dissolve 600g of triphenol A in 2600g of ether, then add 500g of triethylamine and stir evenly. Control the reaction temperature at 0°C, add the above mixed solution dropwise to the ether solution of cyanogen chloride, and add dropwise for 1 hour. After the dropwise addition is complete, continue to keep warm for 1 hour.

[0021] Pour the reaction materials into a beaker, add 2500ml of deionized water, 2000ml of alkaline water, 1600ml of acidic water, and 2000ml of deionized water*2 in sequence, and repeat the steps of washing, resting, layering, and collecting the feed solution.

[0022] Add 200 g of anhydrous sodium sulfate to the collected feed liquid, filter and collect the feed liquid, add it to a 3000ml four-neck flask, carry out ne...

Abstract

The invention discloses triphenol A type cyanate ester and a preparation method thereof. Used raw materials are triphenol A, aether, triethylamine and cyanogen chloride. The triphenol A type cyanate ester prepared by the preparation method is quite good in manufacturability and repeatability and quite stable in yield and quality, the content of the product is greater than or equal to 98.5%, the highest laboratory scale yield can reach 99.03%, and the melting point is 78-81 DEG C. The triphenol A type cyanate ester product prepared by the preparation method has hydrothermal resistance, can be applied in environments higher in hydrothermal demand, and meets a special application demand of a client.

Description

technical field [0001] The invention belongs to the field of synthesis of organic polymer materials, and in particular relates to a triphenol A type cyanate and a preparation method thereof. Background technique [0002] Cyanate resin is a new type of high-performance thermosetting resin, which has outstanding electrical properties, and has excellent dielectric properties and dielectric loss values ​​in a wide frequency range. The basic raw material of materials and aerospace structural materials, cyanate ester resin has been recognized as one of the most competitive resin qualities in the 21st century. [0003] Bisphenol A cyanate resin, which is widely used in the market at present, has very excellent comprehensive properties. It not only has the same operation and processing performance as traditional epoxy resin, but also has excellent heat resistance (Tg=290°C) unique to cyanate resin, excellent dielectric properties, and wide frequency band from X-band to W-band It h...
