A kind of epoxy resin purification method

Abstract

The invention relates to the technical field of epoxy resin processing, in particular to a method for purifying epoxy resin. The method adopts extraction equipment for extraction, and the extraction equipment includes a water bath tube, a heating mechanism, a reaction mechanism, an installation mechanism, a driving mechanism, A storage mechanism and a fixed seat; the method includes the following steps: put the extracted and stored raw materials into the storage mechanism, add a purified reaction liquid to the reaction mechanism 3; then put the storage mechanism into the reaction mechanism; install the prepared reaction mechanism on the installation Mechanism: add an appropriate amount of water to the water bath tube, and the heating mechanism will heat the water in the water bath tube to the required temperature; place the reaction mechanism in the water bath tube; after the purification is completed, take the reaction mechanism out of the water bath tube and place the storage mechanism Disassemble. The present invention uses a water bath to heat the reaction mechanism, so that the heating area is wider and the heating is more uniform.

Description

technical field [0001] The invention relates to the technical field of epoxy resin processing, in particular to a method for purifying epoxy resin. Background technique [0002] All polymer compounds containing epoxy groups in the molecular structure are collectively called epoxy resins; the cured epoxy resin has good physical and chemical properties, and it has excellent bonding strength to the surface of metal and non-metal materials. Good electrical properties, small set shrinkage, good dimensional stability, high hardness, good flexibility, stable to alkali and most solvents, so it is widely used in various departments of national defense and national economy for casting, impregnation and lamination Materials, adhesives, coatings, etc. [0003] Purification is required during the processing of epoxy resin, and the current purification method is mainly to centrally heat the raw materials by means of electric heating and purify them through chemical reactions. This method...

Problems solved by technology

[0007] Aiming at the problems in the prior art, the present invention provides a method for purifying epoxy resin, which uses a water bath to heat the reaction mechanism, which can make the heating area wider and the heating more uniform, and the reaction mechanism adopts a circular array shape The distribution can further increase the contact area between the reaction tube and water, and can also increase the amount of purified raw materials carried at a time; the storage box with multiple mesh structures is used to store raw materials, which can avoid mutual blocking between raw materials, so that the inside of the reaction tube The reaction solution in each part can be fully utilized, which solves the problem of incomplete reaction caused by the easy accumulation of materials; driven by each rotating motor, it will speed up the flow rate of the reaction solution and water, thereby speeding up the chemical reaction speed, effectively Reduce the time required for purification processing and improve production efficiency
