Preparation method of high-solid-content PAE resin paper wet strength agent

Abstract

The invention aims to manufacture a high-solid-content PAE resin paper wet strength agent. Compared with a traditional PAE resin wet strength agent with the low solid content of 12.5%, the PAE resin wet strength agent has the advantages that the solid content is low, wherein the solid content of the prepared novel PAE wet strength agent can reach up to 25%. The wet strength agent prepared according to the method achieves good flowability and excellent storage stability, wherein the wet strengthening effect on the paper is excellent. The invention discloses a preparation method of a high-solid-content PAE resin paper wet strength agent. A series of technical difficulties that gel is extremely easy to produce in the process of preparing the high-solid-content PAE resin paper wet strength agent, and a final product is high in viscosity, poor in flowability, short in storage time and the like are broken through, the novel paper PAE resin paper wet strength agent is successfully developed,and the transportation cost is reduced.

Description

technical field [0001] The invention relates to the field of papermaking chemicals, and more specifically, relates to a preparation method of a high-solid-content PAE resin paper wet strength agent. Background technique [0002] The wet strength of paper refers to the strength of the paper when it meets water or in a humid environment. Many paper products require high wet strength. The addition of wet strength agents can improve the wet strength of paper under wet conditions. [0003] At present, in the field of papermaking, the common chemicals that can improve the wet strength of paper are roughly as follows, the first category: urea-formaldehyde resin (UF); the second category: melamine-formaldehyde resin (MF); the third category: Polyamide polyamine epichlorohydrin resin (PAE); the fourth category: polyethyleneimine resin (PEI), among these types of wet strength agents, UF resin contains free formaldehyde, which will emit into the air Among them, being absorbed by the h...
