Embodiment 1

[0018] The production of high-strength, tear-resistant, ultra-smooth, high-clean high-temperature resistant stainless steel liner paper includes the selection of raw wood pulp, pulping, sand removal, washing, deflaking, refining, pulping, papermaking and other processes.

[0019] Proportioning is carried out according to the ratio of white kraft softwood pulp: white kraft hardwood pulp=75%: 25% (percentage by weight), requiring wood pulp whiteness more than 90%, beating concentration 3.5~4.5%, beating degree 58~ 63°SR, wet weight 5-7g, average fiber length 1.2-2.0mm.

[0020] Use 330 disc grinding basalt stone grinding discs for refining. After refining, add whitening agent and whitening agent VBL to the slurry tank, add cationic starch 1.2%, paraffin emulsion 10%, and AKD 0.8% in the slurry tank; Add 1.2% of emulsified silicone oil to the pulping box; add 0.3% of CPAM and 0.35% of PAE to the head box (the above percentages are the same as the ratio of the added wood pulp).

Embodiment 2

[0023] Production of high-strength, tear-resistant, ultra-smooth, high-clean high-temperature resistant stainless steel liner paper, including the selection of raw material pulp, pulping, sand removal, washing, deflaking, refining, pulping, papermaking and other processes.

[0024] Proportioning is carried out in the ratio of white sulphate softwood pulp: white sulphite hardwood pulp=75%: 25% (percentage by weight), and the wood pulp requires the same embodiment one.

[0025] Use 330 disc grinding basalt stone grinding discs for refining. After refining, add whitening agent and whitening agent VBL to the slurry tank, add 5% paraffin emulsion, 1.0% cationic starch, and 1.0% AKD to the slurry tank; Add 2.0% of emulsified silicone oil to the pulping box; add 0.3% of CPAM and 0.75% of PAE to the high-level box (the above percentages are the same as the proportion of wood pulp added). Other conditions are the same as in Example 1.

Embodiment 3

[0027] Proportioning is carried out according to the ratio of white kraft softwood pulp: white soda hardwood pulp=75%: 25% (percentage by weight), and the requirements of wood pulp are the same as in Example 1.

[0028] Use 330 disc grinding basalt stone grinding discs for refining. After refining, add whitening agent and whitening agent VBL to the slurry tank, add 20% paraffin emulsion, 0.5% cationic starch, and 0.8% AKD to the slurry tank; Add 1.0% of emulsified silicone oil to the pulping box; add 0.5% of CPAM and 0.25% of PAE to the high-level box (the above percentages are the same as the proportion of wood pulp added). Other conditions are the same as in Example 1.

Abstract

The invention discloses a manufacturing method for a stainless steel lining paper that includes the following steps: adopting white wood pulp as raw material, and white sulfate softwood pulp: white hardwood pulp =70-80wt%: 30-20wt%; adopting short fiber shiny beating method, and 330 disc mill basalt stone lapping to take jordaning; using chemical auxiliary agent that adding 5-20wt% olefin emulsion, 0.5-1.0wt% positive ion starch, 0.5-1.0wt% AKD, 1.0-2.0wt% silicone emulsion, 0.3-0.5wt% CPAM, and 0.25-0.75wt% PAE. It has the advantages of high intension, laceration endurable, super smooth, clean and high temperature endurable. It could fit different manufacture technology requests of stainless steel.

Description

technical field [0001] The invention relates to a special paper, in particular to a preparation method of stainless steel backing paper. Background technique [0002] Stainless steel lining paper is a new type of special industrial paper that is gradually matched with the domestic and foreign stainless steel industry to protect the quality of stainless steel plate products with the vigorous development of the stainless steel industry in recent years. According to the different stainless steel production process, stainless steel lining paper can be divided into: high temperature resistant stainless steel lining paper suitable for hot-pressed stainless steel plate and ordinary stainless steel lining paper suitable for cold-rolled stainless steel plate. In July 2006, it was found through a science and technology search that there are currently domestic manufacturers that provide stainless steel lining paper, but most of the stainless steel lining paper provided are imported fro...
