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) Molar ratio preparation, 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. Various raw materials were placed in a reactor with a water separator, a condenser, a stirrer and a heater, and the reaction was stirred at 140 to 170 ° C and normal pressure for 2 to 4 hours. When the high system temperature reaches 200°C, when the rod climbing phenomenon occurs, N-methylpyrrolidone is injected 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 in a pulverizer, and then the particles are ground into fine powders in a size of 0.005-0.1 mm by a colloid mill. After the fine powder is soaked in methanol or ethanol org...

Abstract

A bisphenol A type polyarylene sulfide ether nitrile resin and a preparation method thereof belong to the technical field of polymer materials. The invention uses 2,6-dichlorobenzonitrile, sodium sulfide and bisphenol A as raw materials, uses N-methylpyrrolidone as a solvent, and completes the reaction in a reactor under normal pressure under the action of catalyst potassium carbonate and dehydrating agent toluene. After the reaction solution is precipitated by the precipitant, the particles obtained by pulverizing the precipitate with a pulverizer are ground in a colloid mill to obtain an emulsified fine powder. Then soak the fine powder in an organic solvent and separate the solid from the liquid in a centrifuge. The liquid enters a rectification tower to rectify and recover the solvent. The solid is washed with boiling water and then dried to obtain the bisphenol A polyarylene sulfide ether nitrile resin of the present invention. The production conditions of the invention are easy to realize, and the production process is safe and environment-friendly. The bisphenol A type polyarylene sulfide ether nitrile resin prepared by the method of the invention has stable performance and can be applied to the fields of aerospace, electronics, machinery, medical treatment, chemical industry and the like.

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 group on the side chain. It is a kind of polymer material with excellent comprehensive properties first developed for the needs of national defense industry and cutting-edge technology since the 1980s. , has high heat resistance, flame retardancy, mechanical strength, UV protection and good creep resistance and other excellent characteristics. Due to its excellent comprehensive performance, it can be widely used in aerospace, electronic packaging, machinery manufacturing, auto parts and other fields. Bisphenol A type polyarylene ether nitrile, as one of polyarylene ether nitrile, is synthesized from bisphenol A and 2,6-dichlorobenzonitrile. Bisphenol A is less expensive than i...
