Abstract

The invention discloses a primary treatment liquid and application thereof in preparing high-strength corrugated paper and belongs to the technical field of paper making. The primary treatment liquidcomprises the following raw materials in parts by weight: 3-6 parts of polyethylene glycol, 4-8 parts of fatty alcohol-polyoxyethylene ether, 1-2 parts of fatty alcohol-polyoxyethylene ether ammoniumsulfate, 2-4 parts of succinic acid alkyl ester sodium sulfonate, 1-0.2 part of cellulase and 50-120 parts of water. The yield, the breaking length and the ring crush index of crude pulp prepared by using a process for preparing original color paper pulp and high-strength corrugated paper are all remarkably prior to those of crude pulp prepared by using the prior art, and the primary treatment liquid meets the national industrial policies of resource conservation, environment protection, circulation economy and energy conservation and emission reduction.

Description

【Technical field】 [0001] The invention belongs to the technical field of papermaking, and in particular relates to a primary treatment liquid and its application in preparing high-strength corrugated paper. 【Background technique】 [0002] The current pulp production methods mainly include chemical, semi-chemical, mechanical and chemical-mechanical processes. Among them, chemical pulping occupies a dominant position among many pulping methods at present. The pulp prepared by chemical cooking is called natural pulp. The low brightness of natural pulp limits its application. Generally, natural pulp can only be produced after bleaching to produce higher-grade paper. If the whiteness of the natural pulp can be improved during the pulping process, the trouble of subsequent bleaching can be saved, the production process can be simplified, the production cost can be reduced, and the use value of the natural pulp can be increased. [0003] In the production process of natural pulp,...
