Problems solved by technology

Since the surface of the stainless steel plate is very smooth, like a mirror surface, the quality requirements for the protective paper—stainless steel release paper are also particularly high. If there are paper defects, it will not be able to effectively isolate the high-temperature stainless steel plate, and it will also cause damage to the surface of the steel plate

Embodiment 1

[0027] The preparation method of a kind of high-smoothness stainless steel release paper of the present embodiment, concrete steps are as follows:

[0028] To the pulp with a beating degree of 30°SR, add 10% of the dry pulp weight of the flame retardant amine pyrophosphate (MPP), 1% of the reinforcing agent silicon carbide powder (SiC), and 0.1% of the retention aid Waxy corn Starch and 2% filler aluminum-silicon eutectic powder (particle size range of 0.5 to 2 microns) are mixed evenly, and the paper machine is mixed at a rate of 50g / m 2 Quantitative papermaking is carried out to obtain the formed paper, and then the surface of the formed paper is coated with a coating solution of 5% of the dry pulp weight, and dried by hot pressing to obtain a high-smoothness stainless steel release paper.

[0029] The coating solution in this example is to stir and gelatinize the waxy corn starch with water at 80°C, then add melamine pyrophosphate (MPP) and aluminum-silicon eutectic powder ...

Embodiment 2

[0032] The preparation method of a kind of high-smoothness stainless steel release paper of the present embodiment, concrete steps are as follows:

[0033] To the pulp with a beating degree of 45°SR, add 15% of the dry pulp weight of the flame retardant amine pyrophosphate (MPP), 2% of the reinforcing agent silicon carbide powder (SiC), and 0.2% of the retention aid Waxy corn Starch and 3% filler aluminum-silicon eutectic powder (particle size range of 0.5 to 2 microns) are mixed evenly, and the paper machine is mixed at a rate of 100g / m 2 Quantitative papermaking is carried out to obtain the formed paper, and then the surface of the formed paper is coated with a coating solution of 5% of the dry pulp weight, and dried by hot pressing to obtain a high-smoothness stainless steel release paper.

Abstract

The invention belongs to the technical field of paper making and discloses high-smoothness stainless-steel isolation paper and a preparation method thereof. The preparation method comprises the following steps: adding a flame retardant, a reinforcing agent, a retention aid and a filler into pulp and uniformly mixing; manufacture paper with pulp on a paper machine to obtain shaped paper; then coating the surface of the shaped paper; performing hot-press drying to obtain the high-smoothness stainless-steel isolation paper. As aluminum-silicon eutectic powder serves as the filler, the tightness of the paper is effectively enhanced, the probability of powder and hair falling is reduced, and the surface smoothness of the stainless-steel isolation paper manufactured by the paper is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high-smoothness stainless steel release paper and a preparation method thereof. Background technique [0002] Stainless steel release paper is also called stainless steel backing paper or stainless steel backing paper. It is an industrial paper inserted to prevent friction between stainless steel plates during the coiling process of cold-rolled high-grade stainless steel plates. Since the surface of the stainless steel plate is very smooth, like a mirror surface, the quality requirements for the protective paper—stainless steel release paper are also particularly high. If there are paper defects, it will not be able to effectively isolate the high temperature stainless steel plate, and it will also cause damage to the surface of the steel plate. Therefore, excellent stainless steel release paper should have good high temperature resistance and high smoothness....
