Abstract

The invention discloses high-intensity corrugated paper and a production process thereof, and belongs to the technical field of paper making. The corrugated paper is prepared through secondary pre-treatment, slurry grinding, filter pressing, pulping, molding and the like. According to paper pulp which is natural in color and is prepared according to the process of the high-intensity corrugated paper, the obtained coarse pulp yield, breaking length and ring crushing index are all higher than those obtained in the prior art.

Description

【Technical field】 [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high-strength corrugated paper and a production process thereof. 【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, for wood raw materials, ...
