Problems solved by technology

[0002] Wet strength agent can be used for different papers to improve the wet strength and dry strength of paper, so as to make the paper better in folding resistance and burst resistance. Wet strength agent is a light yellow, transparent viscous liquid. Such a solution The storage time is relatively short, generally about half a year. The preparation process contains harmful substances such as formaldehyde, and it is easy to deteriorate, so it cannot be stored for a long time

Abstract

The invention discloses an emulsion-type wet strength agent and a preparation method thereof. The emulsion-type wet strength agent is prepared from dimethyl diallyl ammonium chloride, polyamide polyamine epichlorohydrin resin, dicyandiamide, polyethylene glycol monostearate, stearyl myristate, sodium hyaluronate, sodium formate, polyoxyethylene ether, alumina, azodiisobutyronitrile, formic acid, sodium carbonate, a sodium sulfamate aqueous solution and a catalyst. The preparation method comprises the following steps of mixing dimethyl diallyl ammonium chloride, polyamide polyamine epichlorohydrin resin, dicyandiamide, polyethylene glycol monostearate, stearyl myristate and sodium hyaluronate to obtain a uniform mixture, adding sodium formate, polyoxyethylene ether, alumina and azodiisobutyronitrile into the mixture, heating the mixture to a temperature of 40-60 DEG C for a reaction for 1-2h, adding formic acid, sodium carbonate, the sodium sulfamate aqueous solution and the catalyst into the reaction product, carrying out mixing to obtain a uniform mixture and carrying out standing. The emulsion-type wet strength agent is green and environmentally friendly and greatly improves wet strength, tensile strength and folding strength of a paper coated with the emulsion-type wet strength agent.
