The secondarytreatment liquid comprises the following raw materials in parts by weight: 6-10 parts of 1,3-diketone, 2-4 parts of sodium lauryl sulfate, 8-22 parts of urea hydrogen peroxide, 0.3-0.5 part of magnesium oxide, 4-6 parts of sodium hydroxide, and 60-200 parts of water. The secondary treatment liquid provided by the invention is in line with the China industrial policies of resource conservation, environmental friendliness, circular economy, energy conservation and emission reduction.

Description

【Technical field】 [0001] The invention belongs to the technical field of papermaking, and in particular relates to a secondary treatment liquid and its application in producing 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 pul...
