Abstract

The invention provides a paper sheet containing bentonite and a preparation method thereof. The paper sheet contains the following components: bentonite, talcum powder, needle wood pulp, waste paper, retention agent, pulp dispersing agent, antioxidant and water. The preparation method comprises the following steps: 1) drying bentonite and then grinding into powder; 2) mixing the bentonite powder, talcum powder, needle wood pulp, waste paper and water, stirring and pulping, thereby acquiring the pulp in concentration of 5-8%; 3) adding retention agent, pulp dispersing agent and antioxidant, uniformly stirring, pouring the pulp into a mold, pressing and forming; 4) drying the pressed and formed pulp, cutting and forming, thereby acquiring the end product. The paper sheet provided by the invention is degradable, low in cost, excellent in paper sheet property and high in quality; the added bentonite can effectively improve the smoothness, whiteness and writing property of the paper sheet and can promote the quality of the paper products; the technological process is simple; the manufacturing process is free from pollutant discharge and meets the requirement for green development in the modern society.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a paper containing bentonite and a preparation method thereof. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. Paper is a powerful tool and material in exchanging ideas, disseminating culture, developing science and technology and production. Looking back at history, this important substance was invented by the working people in ancient China. [0003] Paper is a sheet-like fiber product used for writing, printing, painting or packaging. Generally, it is composed of the water suspension of plant fibers that have been pulped, staggered on the net, dehydrated initially, and then compressed and dried. China is the first country in the world to...
