A kind of manufacturing method of anti-crack decorative base paper

Abstract

The invention relates to the field of papermaking, in particular to a making method of anti-cracking decoration base paper. The anti-cracking decoration base paper comprises a first half part and a second half part, wherein the first half part is at least prepared from wood pulp, cotton pulp, titanium dioxide, kaolin, wet-strength resin and nylon fibers through mixing, and the second half part is at least prepared from wood pulp, cotton pulp, titanium dioxide, kaolin, wet-strength resin, nylon fibers and metal wires through mixing; the decoration base paper is prepared from materials of the first half part and the second half part through feeding, pulping, deslagging, sizing, papermaking, pressing, drying, calendaring and other steps. Compared with the prior art, the making method has the advantages that the strength of the whole paper is improved by adding the nylon fibers and the metal wires into the pulp, the expansion rate of the decoration base paper during transferring and dipping is guaranteed, the decoration base paper cannot deform or crack after being used for a long time, and meanwhile, other performance of the decoration paper isn't affected.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to the manufacture of decorative base paper. Background technique [0002] Decorative base paper is a kind of industrial special paper made of high-quality wood pulp and titanium dioxide as the main raw materials through special technology. After printing and melamine resin impregnation, it is mainly used for the protective layer paper of fiberboard, particle board and other wood-based panels. , Surface paper and bottom paper. When the decorative base paper is used as the protective layer paper, it will be exposed to the outside. Not only may it be exposed to sunlight, but it will also be corroded by water vapor or engraved by hard objects. Therefore, after a long period of use, the decorative base paper will more or less have some quality problems: for example Bumps and mold caused by moisture erosion, discoloration and cracks caused by sunlight, depressions and cracks caused by impacts...

AI Technical Summary

Problems solved by technology

More serious decorative base paper will be deformed, cracked, discolored, bulged and blistered, etc.

Once there is a problem with the decorative base paper, it is impossible to repair. Due to the composite process of the decorative base paper and the panel, when the decorative base paper has a problem, it means that the appearance of the entire panel is damaged, resulting in the scrapping of the entire panel, and more seriously, the scrapping of the entire furniture piece.
