Abstract

The invention discloses a kraft paper wet strength agent and a preparation method thereof. The kraft paper wet strength agent comprises glyoxal-melamine, chloropropylene oxide, sodium dodecyl sulfate, ethyl cellulose, barium sulfate, isopropyl palmitate, octyl methoxycinnamate, p-hydroxybenzoate, dibutyl phthalate, aliphatic binary aldehyde, urea, an ammonium bicarbonate aqueous solution and polybasic acyl chloride. The preparation method comprises the following steps of stirring glyoxal-melamine, chloropropylene oxide, sodium dodecyl sulfate, ethyl cellulose and barium sulfate to obtain a uniform mixture, heating the mixture to a temperature of 60-70 DEG C, adding isopropyl palmitate, octyl methoxycinnamate, p-hydroxybenzoate, dibutyl phthalate, aliphatic binary aldehyde, urea, the ammonium bicarbonate aqueous solution and the polybasic acyl chloride into the mixture, carrying out stirring for a reaction for 1-3h and carrying out standing. The kraft paper wet strength agent greatly improves paper wet strength and dry strength.

Description

technical field [0001] The invention relates to the field of papermaking treatment agents, in particular to a wet strength agent for kraft paper and a preparation method thereof. Background technique [0002] Wet strength agents can be used for different papers, such as bag paper, toilet paper, kraft paper, etc. The wet strength agents in the prior art are generally based on PAE wet strength agents, but for different papers, different wet strength agents should be used. Now Although the wet strength agent used for kraft paper has a certain wet strength performance, the effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to provide a wet strength agent for kraft paper and a preparation method thereof. The affinity between the wet strength agent and the kraft paper is strong, and the wet strength performance is better. [0004] The present invention adopts the following technical solutions to solve technical problems: [0005]...
