Embodiment example 1

[0026] Take 2,6-dichlorobenzonitrile: (n+m):potassium carbonate:N-methylpyrrolidone:toluene=1:1:(1.1~1.5):(6~8):(1.2~1.5) Raw materials are prepared in molar ratio, where n is the amount of sodium sulfide, m is the amount of bisphenol A, and the ratio of n to m is 1:9. Put various raw materials in a reaction kettle equipped with water separator, condenser, stirrer and heater, stir and react at 140~170°C under normal pressure for 2~4 hours, then distill toluene through water separator, liter The temperature of the system is raised to 200°C, and when the phenomenon of rod climbing occurs, inject N-methylpyrrolidone into the reaction kettle to dilute the reaction product so that the reaction product can be quickly put into the precipitation kettle for precipitation. The obtained precipitate is dried and pulverized into particles with a particle size of 0.5-1.5 cm with a pulverizer, and then the above-mentioned particles are ground into a fine powder with a size of 0.005-0.1 mm th...

Abstract

The invention provides a bisphenol A type polyarylene sulfide ether nitrile resin and a preparation method of the bisphenol A type polyarylene sulfide ether nitrile resin, belonging to the technical field of high polymer materials. The bisphenol A type polyarylene sulfide ether nitrile resin is prepared by carrying out normal-pressure reaction on 2,6-dichloro-cyanobenzene, sodium sulfide and bisphenol A as raw materials in N-methyl-pyrrolidone as solvent under the action of catalyst potassium carbonate and dehydrating agent toluene; precipitating the reaction solution through a precipitating agent, crushing the precipitate by a crushing machine to obtain particles, and grinding the particles in a colloid mill to obtain emulsified fine powder; and soaking the fine powder in organic solvent and carrying out solid-liquid separation through a centrifugal machine, entering the liquid to a rectifying tower for rectifying and recovering solvent, washing the solid with boiling water and drying to obtain the bisphenol A type polyarylene sulfide ether nitrile resin. The preparation method has the advantages that the production conditions are easy to realize and the production process is safe and environment-friendly; and the bisphenol A type polyarylene sulfide ether nitrile resin prepared by the preparation method is stable in performance and can be applied the fields such as aerospace and spaceflight, electronics, machinery, medical treatment and chemical industry.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a bisphenol A type polyarylene sulfide ether nitrile resin and a preparation method thereof. Background technique [0002] Polyarylene ether nitrile is a kind of thermoplastic polymer with nitrile groups on the side chain. It is a kind of polymer material with excellent comprehensive properties developed for the needs of national defense and cutting-edge technology since the 1980s. , has excellent characteristics such as high heat resistance, flame retardancy, mechanical strength, UV protection and good creep resistance.
