High-strength fly ash ultrafine fiber composite base paper and manufacturing method thereof

Abstract

The invention discloses high-strength fly ash ultrafine fiber composite base paper. According to the invention, an antibacterial agent is prepared into a mixed antibacterial slurry, and the slurry is added into the raw materials. Compared to traditional spraying, sizing, coating and impregnation methods, with the method provided by the invention, an antibacterial effect is long-lasting, the method is environment-friendly, and the method does not cause environment pollution. According to the invention, fly ash ultrafine fiber and water hemp fiber are modified and re-spun, such that novel composite fiber is obtained. Fly ash ultrafine fiber defects of high brittleness and low toughness are ameliorated, and water hemp fiber strength is improved. With the composition of the two, paper toughness and strength are significantly improved. Propyl triethoxysilane isocyanate and other effective additives are added. Si-C bond can form chemical bond with hydroxyl group in cellulose, such that a special surface property can be provided for fiber. With the method provided by the invention, the prepared composite base paper has the advantages of high strength, wear resistance, bacteria resistance, and mosquito prevention property.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a high-strength fly ash superfine fiber composite base paper and a manufacturing method thereof. Background technique [0002] Paper is a sheet-like fiber product used for writing, printing, painting, or packaging. It is generally made of a water suspension of plant fibers that have been pulped, interlaced on the web, dehydrated initially, and then compressed and dried. With the development and progress of society, people's demand for paper is increasing day by day. In order to meet people's demand for paper, the paper industry has developed rapidly, which has also brought a series of problems. Due to the need for more plant fibers, a large number of trees have been cut down. , the forest area is gradually shrinking. Although some protective measures have been taken, such as returning farmland to forests, the planting speed is much lower than the cutting speed, and the vegeta...

Problems solved by technology

With the development and progress of society, people's demand for paper is increasing day by day. In order to meet people's demand for paper, the paper industry has developed rapidly, which has also brought a series of problems. Due to the need for more plant fibers, a large number of trees have been cut down. , the forest area is gradually shrinking. Although some protective measures have been taken, such as returning farmland to forests, the planting speed is much lower than the cutting speed, and the vegetation coverage has dropped sharply. Therefore, it is necessary to improve the existing technology, increase inorganic fiber or other beneficial Composition to replace plant fibers, not only can save a lot of plant fibers, but also has great significance for reducing the cost of papermaking, protecting forests and the ecological environment, and achieving the sustainable development goal of benefiting future generations in the true sense
