| titleOfInvention | Manufacturing method of paper strengthening agent |
| abstract | The manufacturing method of the intellectual strength enhancer of the present invention comprises the steps of preparing a PA (Polyaminoamine) resin by reacting a mixture containing a secondary amine compound, a tertiary amine compound, and a carboxylic acid derivative; preparing a polyaminoamine-epichlorohydrin (PAE) resin by adding epichlorohydrin to the PA resin and adding a secondary amine catalyst; Including, in the step of producing the PA resin, characterized in that the degree of crosslinking of the PA resin is controlled by the mixing ratio of the secondary amine compound and the tertiary amine compound, to produce eco-friendly and durable paper can |
