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. The current wet strength agent is mainly PAE wet strength agent. The PAE wet strength agent in the prior art uses organic solvents and formaldehyde polymers in the preparation process, which is harmful to human health, and will produce harmful substances during the preparation process, polluting the environment. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly wet strength agent and a preparation method thereof, which are safe and environment-friendly, and have no poisonous effect on human body. [0004] The present invention adopts the following technical solutions to solve technical probl...
