Problems solved by technology

During the use of conventional paper-making fillers (such as calcium carbonate, talc, kaolin, etc.), due to the high density of the filler itself, it is easy to quickly settle to the bottom after being mixed with plant fibers, resulting in low filler retention. The particle size is far smaller than the fiber, and its own retention also greatly affects the application effect of the filler, which needs to be improved

Abstract

The invention discloses a paper making method with pulp and a product of high-surface-intensity offset printing paper. The paper making method with the pulp comprises the steps that (1) multi-hole calcium silicate and mixed wood pulp fibers are subjected to mixing pulping, mixed pulp is obtained; (2) retention and drainage agents A, sizing agents and retention and drainage agents B are added into the mixed pulp in sequence, even stirring is carried out, papermaking pulp is obtained; (3) the papermaking pulp is subjected to papermaking, squeezing and drying, body paper is obtained; (4) surface sizing agents are used for carrying out surface sizing on the body paper, and the offset printing paper is obtained. The multi-hole calcium silicate is used as the papermaking padding, during a papermaking process, paper pulp / padding medium-high-concentration mixing pulping, CS / CPAM double-element retention and surface sizing agent formula improving and other measures are used, the padding retention rate is improved, paper intensity is effectively improved, and the waterproof performance, the oil resistance, the paper surface intensity, the tensile strength and other performance indexes of paper are obviously improved.

Description

technical field [0001] The invention relates to filled paper and a manufacturing method thereof, in particular to high-surface-strength offset printing paper filled with porous calcium silicate and a manufacturing method thereof, and belongs to the field of offset printing paper manufacturing. Background technique [0002] With the development of the publishing industry, the demand for offset printing paper is increasing. Offset printing has the characteristics of soft tones, low cost of plate making, large-format plates and fine lines of printing dots, etc., so offset printing paper has been greatly developed in recent years. [0003] Papermaking filler is the largest component of paper material except fiber. By adding filler, it can reduce the production cost of paper, improve the evenness, opacity and whiteness of the paper page, adjust the ink absorption of the paper, and increase the quality of the paper. printability etc. During the use of conventional paper-making f...
