| titleOfInvention | A kind of preparation method of aldehyde-free water-based cardanol ketone amine epoxy curing agent |
| abstract | The application relates to the technical field of epoxy curing agents, and specifically discloses a preparation method of an aldehyde-free water-based cardanol ketone amine epoxy curing agent. The method comprises the following steps: mixing cardanol or a mixture of cardanol and other phenols with polybasic aliphatic amines or alicyclic amines, and then reacting with ketones to obtain an intermediate water-based cardanol ketone amine epoxy curing agent. Product; mix epoxy resin and block polyether polyol, heat and melt, at 50-100 ℃, add catalyst to carry out condensation reaction, after the reaction is completed, an emulsifier with epoxy functional group and hydroxyl functional group is obtained; the above obtained The emulsifier is added to the intermediate product of the water-based cardanol amine epoxy curing agent, and the temperature is raised to 60-80 ° C to carry out the reaction, and after the reaction is completed, the aldehyde-free water-based cardanol amine epoxy curing agent is obtained. The epoxy curing agent prepared in the present application has low VOC content and excellent corrosion resistance, toughness and stability. |
