A new material of juxtaposed fiber composite paper

Abstract

The invention relates to a paralleling fiber composite paper new material, which is obtained by compounding fibers with parallel structure and papers; one side where the fibers with the parallel structure is bonded with papers is a low-melt-point hot-sealing polymer, and the other side is high-melt-point polymer; the melt point of the low-melt-point hot-sealing polymer is 40-150 DEG C, and the melt point of the high-melt-point polymer is higher than the low-melt-point hot-sealing polymer; finally, the tensile and tear strengths of the prepared composite paper new material are high, and the new material has extremely good economic value and promotion value. By compounding the reinforced fibers with paper surfaces, the new material has the advantages of small consumables, low cost and low requirement on paper materials before compounding; meanwhile, the bonding agent can display the bonding effect through hot pressing, thus the new material can overcome the problem of inconvenient use, high cost and easy generation of harmful and toxic matters of the traditional bonding agent.

Description

technical field [0001] The invention belongs to the field of papermaking and relates to a new material of juxtaposed fiber composite paper. Background technique [0002] The strength of paper refers to the resistance of the paper industry to various mechanical forces, generally including transverse / longitudinal tensile strength, tear strength and bending strength, etc. It is one of the important indicators to measure the performance of paper. The paper industry is one of the important industries in my country. In recent years, with the rapid development of my country's paper industry, people's demand for high-grade paper products has increased significantly, and the improvement of paper strength has become more and more important. [0003] In order to meet people's demand for high-strength paper, researchers have done a lot of research. For example, the patent CN105696409A uses sulfuric acid to pretreat the calcium silicate filler, adds the treated filler to the plant fiber...

Problems solved by technology

However, the amount of coating materials in the above-mentioned coated paper is large, which is easy to cause waste of resources. The composite paper obtained by coating cannot be used as a product with air permeability requirements. When the surface roughness of the paper is large, the unevenness of the paper surface makes the The coating process is prone to leaks, which affect the overall performance of the composite paper obtained by coating. In addition, the adhesives commonly used in coating often produce toxic and harmful gas emissions, which have adverse effects on the environment.
