Embodiment 1

[0048] A method utilizing the comprehensive treatment device to process aged resin, the method comprising the steps of:

[0049] (1) Add back and forth water outside the device into the extraction kettle 1 through the feed port, heat, start stirring, and simultaneously add toluene and the aging resin to be treated to dissolve; wherein, the aging resin: toluene: the mass ratio of water is 1: 2:5; the heating temperature is 70°C, the extraction time is 30min, and the stirring speed is 400r / min.

[0050](2) The mixed solution that has been extracted is transported to the phase separator-2 by means of tangential feeding through the material pump-6 for sedimentation and separation for 30 minutes. After the mixture settles and stratifies in the phase separator-2, it is divided into three phases , the upper layer is toluene resin clear liquid, the middle layer is aging resin, and the lower layer is waste water; the upper layer of toluene resin clear liquid passes through the top mate...

Description

technical field [0001] The invention relates to the technical field of processing by-products in the production process of epoxy resin, in particular to a comprehensive processing device for aging resin and a processing method thereof. Background technique [0002] Aging resin is a by-product of epoxy resin production due to oxidation, chemical action, etc., caused by aging and yellowing of epoxy resin during the production process of epoxy resin. For a long time, aging resin has been regarded as solid waste, which is disposed of by incineration, landfill and other methods. In recent years, with the increasing requirements of environmental protection, the cost of using the original method of processing is also getting higher and higher. The processing of aging resin has attracted the attention of various manufacturers, and various recycling technologies for aging resin have emerged. [0003] The aging resin contains 15-25% of recyclable epoxy resin, 10-15% of toluene and 40...
