Embodiment 1

[0018] The raw material is long-fiber pulp (such as kraft softwood pulp, etc.), the average length of the fiber is between 1.5 and 2.0 mm, and the pulp does not contain chloride ions and sulfate ions as much as possible.

[0019] Firstly, the pulp is half-beated in a Dutch beating machine (due to the long length of pulp fibers, it needs to be half-beaten), and it is beaten in series in four double-disc mills; wherein, the beating concentration of half-beating is 3-4 %, the degree of beating is 16-18°SR, the wet weight is 7-8g, the average length of pulp fibers after beating is 1.5-1.7mm, of which more than 90% are 0.8mm, and less than 0.2mm is no more than 5%; The concentration is 3.5-5.5%, the degree of percussion is 25-35°SR, the wet weight is 5-6g, the average length of pulp fibers after beating is 1.2-1.4mm, of which more than 80% are 0.8mm, and less than 0.2mm does not exceed 10% . A morpholine unit oligomerization gas phase corrosion inhibitor was prepared from morpholi...

Embodiment 2

[0028] The first step is to add polyacrylamide in the pulp according to the mass percentage concentration of 0.2%, and carry out base paper making on the fourdrinier multi-cylinder paper machine, and press lightly;

[0029] The second step adopts the compounding technology to compound the high glass transition temperature polymer PE on the back of the paper base. The extruder temperature is 300°C, the screw speed is 65rpm, the compounding line speed is 70m / min, the pressing roller pressure is 0.392mPa, and the compound film is quantitative 4g / m 2 ;

[0030] The third step is to mix the following ingredients according to the weight ratio to prepare the corrosion inhibitor: 25 parts of morpholine unit oligomerization gas phase corrosion inhibitor, 8 parts of dimethylpiperazine, 7 parts of sodium tungstate, 0.005 parts of lake blue dye and 60 parts deionized water;

[0031] The fourth step is to add 2.5% fumed silicon, 0.25% polyacrylamine, and 1.2% carboxymethyl cellulose to t...

Embodiment 3

[0034] The first step is to add polyacrylamide in the pulp according to the mass percentage concentration of 0.3%, and carry out base paper making on the fourdrinier multi-cylinder paper machine, and press lightly;

[0035] The second step adopts compounding technology, compounding high glass transition temperature high polymer PE on the back of the paper base, extruder temperature 340 ℃, screw speed 79rpm, compound line speed 80m / min, pressure roller pressure 0.686mPa, compound film quantitative 5g / m 2 ;

[0036] In the third step, the following ingredients are mixed according to the weight ratio to prepare the corrosion inhibitor: 30 parts of morpholine unit oligomerization gas phase corrosion inhibitor, 10 parts of dimethylpiperazine, 10 parts of sodium tungstate, 0.01 part of lake blue dye and 70 parts deionized water;

[0037] The fourth step is to add 3% nano-silicon, 0.3% cationic polyacrylate, and 1.7% methylcellulose to the corrosion inhibitor according to the mass ...

Abstract

The invention discloses a method for preparing stainless steel pad paper, which comprises that: adding non-ionic intensifier into paper pulp and processing raw paper preparation and compression on the long-network multi-cylinder machine; compounding the high polymer with high vitrification temperature on the back surface of basic paper; mixing the morpholine oligomer vapour phase inhibitor in 20-30 deals, the dimethyl piperazine in 5-10 deals, the sodium tungstate in 5-10 deals, the blue dye in 0.001-0.01 deals and the deionized water in 50-70 deals to prepare the inhibitor; adding silicon porous absorption material, polyacrylic acid salt disperser and modified macromolecule film former to be plated on the surface of basic paper; drying paper with hot wind, to be burnished, coiled and cut. The invention utilizes the high polymer with high vitrification temperature to improve the mechanical strength and air tightness of basic paper with the functions of moisture-proof and anti-leakage. And the invention plates the metallic inhibitor suspend on the surface of basic paper, therefore, the time of anti-rust can reach 5-10 years.

Description

technical field [0001] The invention relates to the technical field of gaskets and rust prevention for stainless steel materials, in particular to a method for preparing stainless steel material protective gasket paper. Background technique [0002] In order to meet the processing requirements of various metal products, stainless steel materials are usually processed into plates, mesh materials and wires, etc., and in the billet forming process (such as rolling), in order to avoid friction and oxidation between steel plates or between finished products, usually need The gasket material is used to prevent wear and corrosion on the surface of the steel plate or between finished products. Antirust paper, as a functional protective paper to prevent metal materials and their products from abrasion, corrosion, and rust, was originally widely used in the long-term packaging of ordnance equipment in the military industry. Such as firearms, cartridges, artill...
