Composite body paper resisting corrosion of acid and alkali and manufacturing method thereof

Abstract

The invention discloses composite body paper resisting corrosion of acid and alkali. An antibacterial agent is made into a mixed antibacterial sizing agent to be added into a raw material, so that compared with the traditional method such as spraying, gluing, coating, soaking and the like, the antibacterial performance is durable, environmental protection can be realized, and environmental pollution can be avoided; ceramic fibers and hemp fibers are modified and re-spun to form a novel composite fiber, so that not only is the weakness of the ceramic fiber such as large brittleness and small flexibility improved, but also the strength of the hemp fiber is improved, and the flexibility and strength of the paper are obviously improved by compositing the ceramic fibers and the hemp fibers; by adding a silane coupling agent KH792 and other effective additives, a Si-C bond can form a chemical bond with hydroxyl in the cellulose, so that a special surface character is given to the fiber, the manufactured composite body paper has good acid and alkali corrosion resistance, excellent dry and wet strength and compact and smooth surface, and is environment-friendly, non-toxic and excellent in physical performance; and moreover, the environmental pollution caused by the abandoned waste newspaper can be solved, the waste is converted into treasure, and the reality significance can be realized for saving the energy and reducing the emission.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an acid and alkali corrosion resistant 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 vegetat...

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
