Problems solved by technology

The production of the above-mentioned stainless steel backing paper cannot be completed by using the existing ordinary cultural paper machine, and the ordinary cultural paper machine needs to be modified accordingly, and equipment should be added, which increases the production cost and is not conducive to rapid production
Moreover, the use of coniferous wood and broad-leaved wood to make log pulp requires cutting down a large amount of wood, resulting in the destruction of forest resources, which is not conducive to protecting the natural environment on which human beings depend.

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0030] Such as figure 1 As shown, a method for preparing stainless steel liner paper using waste paper as a raw material includes the following steps:

[0031] Step 1: Use waste paper with stainless steel lining paper as raw material, disintegrate it into slurry in the waste paper pool of the paper machine, and store it in the waste paper tower;

[0032] Step two, the slurry is pumped to the broken paper tank for storage after being decontaminated by a decomposer;

[0033] Step 3: Add dry strength agent and guar gum in proportion to the mixing tank, and pump to the pulp tank of the paper machine after mixing;

[0034] Step 4: Adjust the slurry concentration of the pulp tank of the paper machine to 4%-5%, and then pump it to the white tank outside the paper to dilute it to a concentration of 1%;

[0035] Step 5, remove the gas in the slurry in the deaerator,...

Abstract

The invention discloses a method for preparing a stainless steel interleaving paper by a wastepaper. The method comprises the following steps of: based on 100% of stainless steel interleaving wastepaper as raw material, disintegrating by a coiling paper-breaking pond, and purifying in a screening way by a papermaking short-recycle system, so that the raw material can be used for the production of a paper machine. Dry strength resin, guar gum and fire retardant are added into sizing agent to replace the pulp sizing and surface sizing (coating). According to the preparation method disclosed by the invention, the environment protection is benefited, the energy can be saved, the process can be simplified, the production efficiency can be improved, and the production cost can be reduced.

Description

Technical field [0001] The invention relates to a method for preparing stainless steel lining paper, in particular to a method for preparing stainless steel lining paper using waste paper as a raw material, and belongs to the technical field of papermaking. Background technique [0002] Stainless steel liner is a stainless steel cold-rolled sheet in the process of rolling, pickling, leveling, grinding, refining, etc., to prevent scratches and other damage caused by slip, high tension, high temperature, and friction between metal sheets. It is a kind of special industrial paper that improves the surface quality of cold-rolled sheet and protects between layers. High temperature resistant stainless steel craft pad paper requires high surface strength, tensile strength and other physical strength; it must have a certain degree of smoothness, and the dust of the paper should be controlled to the minimum; the paper is neutral, and the CL- content is less than 100mg / kg, The content of ...
