| titleOfInvention | A kind of preparation method of environmental protection low chlorine wet strength agent |
| abstract | The invention discloses a preparation method of an environment-friendly low-chlorine wet strength agent. A polybasic acid of ≥ 3 is copolymerized, and then modified by adding epichlorohydrin to obtain a polyamide epoxy resin, which is then mixed with enzymatic hydrolyzed hydroxypropyl guar gum to obtain the environment-friendly low-chlorine wet strength agent. The present invention forms a branched structure in the first stage of polymerization, has high branching degree, low reaction temperature in the polymerization stage, and reacts with natural and environmentally friendly enzymatic hydrolysis guar gum derivatives to consume residual epoxy chlorine in polyamide epoxy resins. Propane, the final product has lower organochlorine content, and at the same time has more excellent application properties, and the resulting paper has better wet strength and wet strength retention. |
