Abstract

The invention discloses a primary treatment solution for producing high strength corrugated paper by utilizing a bleaching process and application thereof, and belongs to the technical field of papermaking. The primary treatment solution is prepared from the following raw materials in parts by weight: 8-12 parts of octadecanamide, 5-9 parts of fatty alcohol-polyoxyethylene ether, 1.5-2.5 parts ofsodium dodecyl benzene sulfonate, 2.4-4.5 parts of sodium alkyl ester sulfonate succinate, 0.1-0.2 part of cellulase and 70-160 parts of water. The process accords with the industrial policy of national resource conservation and circular economy, and can be used for reducing pollution and improving economic benefit by developing and utilizing rich and waste material resources of bagasse and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of papermaking, and in particular relates to a primary treatment liquid for producing high-strength corrugated paper by a bleaching process and its application. 【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 bleached sugarcane pulp. The low brightness of bleached sugarcane pulp limits its application. Bleached sugarcane pulp generally needs to be bleached to produce higher-grade paper. [0003] With the continuous expansion of the paper industry and the continuous expansion of the application of pulp, the supply of wood, which was originally the main raw material for papermaking, is gradually in short supply, resulting in excessive deforestation and affectin...
