Paper pulp prepared from maize straw, preparation method thereof and paper product prepared from paper pulp

Abstract

The invention relates to maize straw paper pulp, which is prepared from maize straw serving as a raw material. The whiteness of the maize straw paper pulp is 38-60 percent ISO (International Standardization Organization), the bulk is 1.8-2.5 cm<3> / g, the tensile index is 35-65 N.m / g, the folding resistance is 10-40 times, the fracture length is 4.0-6.5 km, the air permeability is 70-200 ml / min, the ash content is 5-10 percent, the tear resistance is 180-260 mN, and the tear resistance index is 3.0-4.2 mN.m<2> / g. The paper pulp has good performance parameters, can replace the conventional wood pulp and can be used for preparing cultural paper and paper for daily use. A preparation method of the maize straw paper pulp comprises stock preparation, cooking and black liquor extraction, wherein the heat preserving time in the cooking process is 0-50 minutes.

Description

technical field [0001] The invention relates to a corn stalk pulp, a preparation method of the corn stalk pulp, and cultural paper products and household paper products made from the corn stalk pulp. Background technique [0002] Due to the increasing shortage of wood resources in the world, it has become the goal pursued by various paper-making enterprises to produce pulp and paper without destroying forests and the environment. As a solution to this problem, the technology of making pulp from non-wood plant fibers using annual or biennial plants such as: farmland waste, bamboo, sugarcane stalks discarded after sugar production, rice and wheat straw, etc. as the main material has been attracting attention. [0003] Although the pulping of various annual or biennial plants has been studied in the prior art, and non-wood fiber pulps with good properties have been obtained, it is generally considered that the content of cellulose in corn stover is too low, for example, cellulo...

AI Technical Summary

Problems solved by technology

[0012] There are many shortcomings in the cultural paper and household paper of the prior art. Most of the original wood pulp is used. Because a large amount of wood needs to be cut down, the ecological balance of the environment is seriously affected and long-term adverse consequences are caused; some non-virgin wood pulp is prepared. The tensile strength, softness and water absorption of cultural paper cannot meet the specified standards;

[0013] Therefore, in view of the defects in the above-mentioned prior art, there is no more detailed description in the prior art on how to use corn stalks to prepare cultural and household paper that meets the requirements. In view of this, the present invention is proposed
