| titleOfInvention | Synthesis method of low-molecular weight epoxy resin |
| abstract | The invention provides a preparation method of low-molecular weight epoxy resin. The method comprises the following steps: adding bisphenol A, epoxy chloropropane, potassium carbonate having grain size of 100-300 nanometer and solvent into a reactor for reaction; and distilling or rectifying the reaction liquid, and recycling the solvent to obtain the low-molecular weight colorless liquid bisphenol A type epoxy resin. The same effect is obtained by replacing bisphenol A with bisphenol S, bisphenol F or bisphenol fluorene to synthesize corresponding bisphenol S, bisphenol F or bisphenol fluorene type low-molecular weight epoxyresin. The method for synthesizing the low-molecular weight epoxy resin has the advantages of low reaction temperature, short reaction time, simple operation, high epoxy value of product, no production of industrial wastewater and good industrial prospect. |
