Abstract

The invention discloses a papermaking additive composition and a preparation method thereof. The papermaking additive composition is prepared from the following components in parts by weight: 30-35 parts of polyoxypropyl glyceryl ether, 20-30 parts of stearin, 20-30 parts of glass fibers, 10-15 parts of calcium carbonate whisker, 10-15 parts of polyhexamethylene guanidine hydrochloride, 3-5 parts of 4,4'-diphenylmethane-diisocyanate and 2-5 parts of sodium hydrogen disulfate. According to the papermaking additive composition, bad bubbles in the paper pulp preparation process can be eliminated, and pulp can be well dispersed, so that the paper has the excellent water-retaining property, antibacterial property and mechanical strength and can be preserved for a long time.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a papermaking auxiliary composition and a preparation method thereof. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. Paper is a flaky fiber product used for writing, printing, painting or packaging. Paper is a powerful tool and material in the exchange of ideas, dissemination of culture, development of science and technology and production. However, paper has its shortcomings, such as low strength, easy to mold, etc., and it is difficult to store for a long time. [0003] Although the existing papermaking technology is relatively mature, its process is still very complicated, requiring multiple processes and adding various additiv...
