Embodiment

[0024] (1) Take 1 kg of sodium dibutylnaphthalene sulfonate and add it to 260 kg of warm water (water temperature not exceeding 50°C) or cold water, and stir fully to dissolve it completely; add 30 kg of ammonium citrate sequentially under stirring , 20 kilograms of benzoic acid, 15 kilograms of sodium nitrite, 4 kilograms of ammonium acetate, 8 kilograms of isopropanolamine, and 3 kilograms of dicyclohexylamine nitrite were all dissolved completely, and then stirred for 10 minutes to obtain the present invention. Anti-rust agent.

[0025] (2) The wet paper base is manufactured according to the conventional wrapping paper production process.

[0026] (3) Before the wet paper base of the papermaking line enters the drying cylinder, the stainless steel anti-corrosion agent is evenly sprayed on one side of the wet paper base at an amount of 0.4 kg per square meter, dried and packaged by the drying cylinder, and the stainless steel anti-corrosion wrapping paper is obtained .

Abstract

The stainless steel rust-preventing packaging paper is made up by uniformly spraying stainless steel rust-preventing agent on the surface of one side of wet paper base before which is fed into drying cylinder on the production line of packaging paper, and its rust-preventing agent comprises ammonium citrate, benzoic acid, sodium nitrite, ammonium acetate, isopropanolamine, dicyclohexylamine nitrite, neckel and water.

Description

technical field [0001] The invention relates to stainless steel anti-corrosion packaging paper and a manufacturing method thereof, and is particularly suitable for long-term storage packaging of stainless steel products and parts. Background technique [0002] Metal (including stainless steel) products, in the process of storage and transportation, because the ambient atmosphere contains trace substances such as water vapor, oxygen, acid, alkali, salt, carbide, etc., it will occur in a certain temperature, humidity and time. Physical and chemical effects. This physical and chemical reaction first starts from the defect on the metal surface, and proceeds from the outside to the inside, forming an ion exchange. It can be observed macroscopically or microscopically, and rust spots (called rust spots) are formed on the metal surface. In order to reduce or prevent the loss of metal due to corrosion and the decline or loss of the function of parts, the use of vapor phase antirus...
