Abstract

The invention relates to the technical field of corrugated board processing, in particular to a corrugated carton penetrant made of tannin of natural quebrachos and a preparation method of the corrugated carton penetrant. The corrugated carton penetrant made of the tannin of the natural quebrachos is a natural board degumming prevention agent obtained after special chemical modification of a tannin product of a natural polyphenol structure extracted from the natural quebrachos grown in northeast of Argentina, is a natural product integrating unique penetrability, water resistance and natural viscosity, and is widely applied to corrugated boards with the degumming problem due to high fiber density and overlarge paper surface tension. Besides, the unique natural penetrability of the corrugated carton penetrant perfectly solves the problem of degumming of the corrugated boards.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard processing, and in particular provides a natural hardwood tannin corrugated carton penetrant and a preparation method thereof. Background technique [0002] Under the existing technology, in the production of corrugated cardboard, the two reasons that lead to cardboard degumming are: [0003] 1. Due to the excessive surface tension of the paper, it is difficult for the glue to penetrate into the paper. [0004] 2. Since the paper contains low air density and high fiber density, the temperature on the preheater will be quickly transferred to the paper. Therefore, it is necessary to lower the wrap angle of the preheater during operation to prevent excessive glue gelatinized. [0005] Under the current technology, there is no suitable method to assist in solving the technical problem of cardboard degumming. Contents of the invention [0006] In view of the above problems, the presen...
