Abstract

The invention discloses high-intensity filling material paper, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of needlebush pulp, 20 to 30 parts of bagasse pulp, 40 to 60 parts of composite filling materials, 3 to 5 parts of sugar powder and 1 to 5 parts of auxiliary ingredients, wherein the composite filling material contains filling ingredients, fiber ingredients and retention aids. The invention also discloses a preparation method of the high-intensity filling material paper. The filling ingredients, the fiber ingredients and the retention aids are matched to be used as the slurry composite slurry; a cellulose-sugar compound is formed through sugar solution seepage on the surface of wet paper; the paper intensity is enhanced; the production cost is reduced; the preparation method is simple; the industrial production is facilitated.

Description

Technical field [0001] The invention relates to the technical field of paper preparation, in particular to a high-strength and high-filling paper and a preparation method thereof. Background technique [0002] The paper industry occupies a very important position in the national economy. In the 21st century, my country’s paper industry will be a sustained and stable industry. However, my country is a country with a serious shortage of forest resources. Currently, the forest area is only about 175 million hectares. The forest coverage rate is only about 18.2%. In the short term, it is impossible for my country to provide sufficient forest resources to the paper industry for pulping and papermaking. With the rapid development of my country's economy and the enhancement of environmental protection and energy conservation awareness, secondary fibers and papermaking fillers are usually used to replace wood fibers for papermaking, and papermaking fillers are more widely used. The addi...
