Abstract

The invention discloses a corrugating base paper enhancer and a preparation method thereof, wherein the enhancer includes: cationic polyacrylamide, hydroxypropyl chitosan, polyamide polyamine epichlorohydrin resin, a crosslinker, potassium hydroxide, layered silicate, microcrystalline cellulose, a surfactant, NaHCO3 and a coupling agent. The basic material of the enhancer is made from the cationicpolyacrylamide, hydroxypropyl chitosan and polyamide polyamine epichlorohydrin resin and has high positive charge property and can form strong electrostatic effect with fibers and reduce interferencedue to anionic trash in wastepaper; being compounded with the layered silicate and microcrystalline cellulose, the basic material also can improve retention of fine fibers in pulp and increase evenness of paper, thus increasing ring crush compression resistance of the corrugating base paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a corrugated raw paper strengthening agent and a preparation method thereof. Background technique [0002] In order to respond to the requirements of environmental protection and improve economic benefits, the production of corrugated base paper is developing towards low grammage and high strength. In the actual production process, there are two main ways to improve the quality of corrugated base paper: one is to improve the quality of raw materials; the other is to add chemicals. Recycled waste corrugated paper is one of the main raw materials for the production of corrugated base paper. Due to the poor fiber strength and many impurities of waste paper, the strength of the corrugated base paper produced is not high. If we start from the first way and optimize the quality of raw material fibers, this As will increase production costs. High-efficiency corrugating...
