Preparation method of paper for industry

Abstract

The present invention belongs to the technical field of industrial papermaking, and particularly relates to a preparation method of paper for industry. The method comprises: (1) raw material treatment, (2) soaking, (3) washing of paper, (4) pulp grinding treatment, and (5) screening and paper-making. According to the present invention, the method has characteristics of short material pretreatment time, low energy consumption and low equipment investment; the chemical agent is added to the raw materials, such that the yellowing resistance of the paper is enhanced, the storage time is substantially prolonged, the toughness and the softness of the paper can be increased, the smoothness and the antistatic capability of the paper surface are increased, and the water resistance and the moisture-proof property of the paper are improved; and the product can be widely used for printing paper, kraft paper, paper boards, liner paper and other craft paper.

Description

technical field [0001] The invention belongs to the technical field of industrial papermaking, and in particular relates to a preparation method of industrial paper. Background technique [0002] my country's agriculture covers a large area and has vast forest resources. A large amount of discarded straw, wood, bamboo, etc. will be produced in the process of agricultural and forestry production and processing. With the lack of forest resources and the strengthening of environmental protection requirements, although some use of straw has begun. It is used for a small amount of simple reprocessing of organic fertilizers, domestic fuels, livestock feed, edible fungus base materials, and industrial raw materials.

[0002] my country's agriculture covers a large area and has vast forest resources. A large amount of discarded straw, wood, bamboo, etc. will be produced in the process of agricultural and forestry production and processing. With the lack of forest resources and the strengthening of environmental protection requirements, although some use of straw has begun. It is used for a small amount of simple reprocessing of organic fertilizers, domestic fuels, livestock feed, edible fungus base materials, and industrial raw materials. However, due to the constraints of various factors such as the shortage of rural labor force and the high cost of comprehensive utilization of straw, most of the straw is still In the way of direct burning back to the field or discarding in the field, it not only wastes resources, pollutes the environment, but also affects people's health. However, the existing straw papermaking process has complex processes, huge investment in personnel and equipment, high production costs, and high energy consumption. The process caused huge pollution to the environment. At the same time, the existing paper is easy to change color, and the toughness of the paper becomes poor after absorbing water.
