Abstract

The invention discloses an environment-friendly wet strength agent and a preparation method thereof. The wet strength agent comprises the following raw materials in parts by weight: 10-20 parts of diethylenetriamine, 20-30 parts of sodium hydroxide, 30-50 parts of hydroxyethyl cetane cellulose, 20-30 parts of magnesium oxide, 36-40 parts of 1,6-hexanediol diacrylate, 45-50 parts of isostearic acid calcium, 45-50 parts of ethylhexyl stearate, 20-30 parts of propylene glycol stearate, 40-50 parts of simethicone, 60-70 parts of dodecyl trimethyl ammonium chloride, 40-50 parts of binary acid and 20-50 parts of polyhydric alcohols. The preparation method comprises the following steps: agitating for reacting the diethylenetriamine, the sodium hydroxide, the hydroxyethyl cetane cellulose, the magnesium oxide, the 1,6-hexanediol diacrylate and the isostearic acid calcium; adding residual components to carry out thermal reaction after warming up; dropwise adding a pH modifier. By the environment-friendly wet strength agent, the dry tensile strength of paper can be enhanced, and the water resistance of the paper surface can be greatly improved.

Description

technical field [0001] The invention relates to the field of papermaking treatment agents, in particular to an environment-friendly wet strength agent and a preparation method thereof. Background technique [0002] Wet strength agents are mainly used in the paper industry. The amount of different paper types varies greatly.
