| titleOfInvention | Preparation method of nonionic waterborne epoxy resin emulsion and curing agent thereof |
| abstract | The invention discloses a non-ionic waterborne epoxy resin emulsion and a preparation method of a curing agent thereof. The preparation of the nonionic aqueous epoxy resin emulsion comprises the following steps: mixing macromolecular polyoxyethylene and epoxy resin A, adding a catalyst, heating, dropwise adding polyether amine, and stirring to obtain a nonionic emulsifier; uniformly mixing the epoxy resin B, the chain extender and the toughening agent, and carrying out addition reaction to obtain a product of the addition reaction; mixing the nonionic emulsifier, the product of the addition reaction, the cosolvent and water, and heating to obtain the nonionic waterborne epoxy resin emulsion. Preparation of a curing agent comprising: mixing epoxy resin and macromolecular polyethylene glycol uniformly, adding a catalyst, carrying out addition reaction, adding water, and stirring to obtain an adduct; the curing agent is obtained by adding the adduct dropwise to a mixture of the polyamine and the cosolvent and adding water. The emulsion was mixed with a curing agent to obtain a paint film. The paint film has the comprehensive properties of good adhesive force, water resistance, alkali resistance, high toughness and the like. |
