| titleOfInvention | Preparation method and application of low-viscosity polyether type hyperbranched epoxy resin |
| abstract | The invention discloses a preparation method and application of low-viscosity polyether type hyperbranched epoxy resin, and belongs to the technical field of coatings. The preparation method comprises the steps of taking dihydroxybenzoic acid and monofunctional glycidyl ether as raw materials, firstly synthesizing diphenol intermediates with different side group structures, and then further polymerizing the diphenol intermediates and the multifunctional glycidyl ether to synthesize polyether type hyperbranched epoxy resin with an end epoxy group and a polyether framework. The polyether type hyperbranched epoxy resin prepared by the invention has low viscosity, can be used for modifying bisphenol A linear epoxy resin, and is used as a film forming material of high-solid epoxy coating. The solid content of the epoxy coating prepared by the invention is up to more than 90%, and a paint film obtained after the coating is cured has excellent toughness and medium resistance. |
