Embodiment 1

[0064] Add 300g of hydroquinone to a 500ml four-necked bottle, insert a stirring paddle into the middle port of the four-necked bottle, insert a tee pipe into one side port, connect the thermometer and argon gas inlet respectively to the three-way pipe, and insert a side port into The ventilation pipe is connected to the bottom of the four-necked bottle, and one side port is connected with a spherical condenser as an exhaust port. Put the four-necked bottle into the electric heating mantle, and pass high-purity argon gas into the four-necked bottle from the two inlet ports. The flow rate of argon gas is 50ml / min, and the purity of argon gas is ≥99.999%. Turn on the heating until the hydroquinone melts, adjust the argon gas flow to 200ml / min, start the stirring speed to 80rpm, maintain the temperature of the molten hydroquinone at 178°C, and continue the reaction for 1 hour. Put the four-neck bottle into a hot oil bath and cool to room temperature, turn off the argon to obtain ...

Abstract

The invention provides polyether ether ketone and a preparation method thereof. The method comprises: feeding argon into a container containing bisphenol compounds to obtain a complex of bisphenol compounds; mixing fluoroketone, alkali metal carbonate, the complex of bisphenol compounds and Solvents are mixed, and the mixture is subjected to temperature programming treatment to generate the polyether ether ketone. Thus, prior to the preparation of polyether ether ketone, the bisphenols are protected with argon so that they will not be oxidized to quinones when they react with fluoroketones and alkali metal carbonates, so that the color value can be obtained Higher L*, whiter polyetheretherketone solid.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to polyether ether ketone and a preparation method thereof. Background technique [0002] Poly(aryl ether ketone) polymer is an aromatic linear polymer material. It is a new type of semi-crystalline aromatic thermoplastic engineering plastic successfully researched and developed in the late 1970s. It has high temperature resistance, chemical resistance, high Strength, high modulus, high fracture toughness and excellent dimensional stability, etc. A typical representative of poly(aryl ether ketone) polymers is polyetheretherketone, which has a glass transition temperature (Tg) of 143°C, a melting point of 334°C, and a maximum attainable crystallinity of 48%, generally 20%. ~30%. Its density in the amorphous state is 1.265g / cm 3 , the density at the maximum crystallinity is 1.32g / cm 3 . Its crystalline form makes it have outstanding heat resistance and mechanical properties. The ...
