Abstract

The invention discloses a device for purifying a high-temperature-resistant polymer. A heating tank body is connected with a washing tank body through a first valve; a revolving drum is arranged in the washing tank body; the lower end of a washing liquid storage tank is connected with the washing tank body through a second valve and the upper end is connected with an upper cover of the heating tank body through a pipeline and provided with a condenser; and the upper end of the washing tank body is provided with a feeding hole. A method for purifying the high-temperature-resistant polymer comprises the following steps of: a, gasifying a washing solvent in the heating tank body by heating, introducing steam into the condenser through a pipeline for condensing into a pure solvent and keepingthe pure solvent in the washing liquid storage tank for later use; b, smashing the polymer containing the solvent and/or impurities, making the smashed polymer pass through a 20-mesh screen and putting the smashed polymer into the revolving drum from the feeding hole; c, opening the second valve, injecting a certain quantity of solvent into the washing tank body, opening a washing tank heating device, setting to a preset temperature, starting the revolving drum, rotating the revolving drum positively and negatively under program control and mixing the washed polymer for a certain period of time; d, opening the first valve, rotating the revolving drum at a high speed under program control and making the washed solvent leak from the revolving drum and flow back into the heating tank body through the washing tank body under the action of centrifugal force; e, repeating steps a-d in sequence until reaching predetermined times; f, starting the heating device and a vacuumizing device of a washing tank 2, raising the internal temperature of the tank body to 100-300 DEG C for drying and rotating the revolving drum under program control to ensure that a material is uniformly dried.

Description

technical field [0001] The invention relates to a purification device for high temperature resistant resin, and also relates to a purification method for high temperature resistant resin. Background technique [0002] In the process of making resin products, if there are various inorganic or organic impurities mixed, it will reduce the product performance, increase the defective rate and affect the use, so it needs to be removed in the general preparation process to obtain various good Material. For example, polyetheretherketone / polyethersulfone high-temperature resistant materials are often used in electronic and electrical components, which require high purity. They are generally prepared by solution polymerization, using diphenyl sulfone as a solvent, alkali metal carbonate Or sodium hydroxide is used as a catalyst, and finally the solvent and alkali metal salt are removed from the product. Otherwise, the presence of inorganic ions will reduce the electrical insulation ...
