Folding-resistant bobbin paper and processing technology thereof

Abstract

The invention discloses folding-resistant bobbin paper and a processing technology thereof, which are applied to the field of industrial papermaking. The technical problem that the existing bobbin paper is easy to crease and break and has poor toughness is solved. According to the technical scheme, the paper comprises a paper core layer, an extension layer and protective layers; the extension layer is arranged on one side of the paper core layer; the protective layers are respectively arranged on one side of the paper core layer and on the side, far away from the paper core layer, of the extension layer; the paper core layer comprises a raw wood pulp layer and a recycled paper pulp layer; the extension layer comprises a cushion layer, a staggered lamination layer and an adhesion layer which are arranged in sequence, the staggered lamination layer comprises a plurality of continuous fault blocks, an interlayer is arranged at one end of each continuous fault block, and one ends of the adjacent continuous fault blocks are inserted into the interlayers; and the protective layer comprises an elastic cow leather layer and a wear-resistant layer. The toughness of the bobbin paper is improved.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a fold-resistant bobbin paper and its processing technology. Background technique [0002] In the field of papermaking, the quality reference for paper products includes different detection and evaluation standards such as color, toughness, and composition. Among them, the characteristic of toughness can largely guarantee the reliability of paper products during use, especially in industrial The field of paper, including production and application scenarios such as bobbin paper, puts forward high requirements on the toughness of paper products. [0003] Once cracks, tears, etc. appear in the actual use of paper products, it will directly lead to hidden dangers in production. Just in order to solve similar problems and improve the reliability of the product in terms of toughness, paper manufacturers are also constantly trying to try, including formulations and processes, but the large ...
