Embodiment 1

[0024] The manufacturing process of a kind of high temperature resistant stainless steel backing paper provided by the present invention comprises the following steps:

[0025] S1: put 100 parts by weight of hardwood pulp and 60 parts by weight of softwood pulp into a beater and stir to prepare a pulp liquid for use;

[0026] S2: Pour the pulp liquid in step S1 into the steam oven, add 10 parts by weight of polytetrafluoroethylene emulsion, 5 parts of cellulase, and 2 parts of hemicellulase, and pass it through the mixer at a speed of 30r / min Stir and heat to raise the temperature of the steamer to 200°C, boil the slurry, keep it warm for 1min, stop heating, and set aside;

[0027] S3: Add 10 parts by weight of silicon disulfide, 20 parts of sodium silicate and 12 parts of corundum powder into the mixing tank, add water in a ratio of 1:5 by weight, and then start the mixer at a speed of 65r / min. The above-mentioned materials are mixed with water to prepare filler, which is se...

Abstract

The invention discloses a production technology of high-temperature-resistant stainless steel backing paper. The production technology of the high-temperature-resistant stainless steel backing paper comprises the steps of adopting hardwood pulp and softwood pulp as paper pulp, then adding filler to prepare a semi-finished product, and finally, conducting sizing and deacidification treatment. By means of the production technology of the high-temperature-resistant stainless steel backing paper, the technical problem that in the prior art, backing paper cannot meet the requirements of high-temperature environments is solved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a manufacturing process of high-temperature-resistant 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. [0003] Stainless steel lining paper is a kind of special paper used to prevent friction between stainless steel plates during cold rolling of high-grade stainless steel plates. ...
