Abstract

The invention discloses a preparation method of slow-release-type metal antirust paper, and belongs to the field of papermaking. The preparation method comprises the steps that attapulgite, a calciumchloride solution and macroporous silica gel are mixed uniformly, sintered and cooled to the room temperature to obtain a cooled product; the cooled product and deionized water are mixed and beaten, asupernatant and cetyl trimethyl ammonium bromide are taken, mixed, stirred and subjected to extraction filtration to obtain a filter cake, and the filter cake is washed with deionized water, dried and ground into powder to obtain an abrasive; the abrasive and morpholine are mixed, formaldehyde and cyclohexylamine carbonate are added after the temperature is increased, standing is conducted, a dinitrobenzoic acid aqueous solution is added after layering, standing and extraction filtration are conducted to obtain filter residues, and the filter residues are dried to obtain a dried product; thedried product, extracts, Arabic gum and a chitosan solution are mixed and stirred, the pH is adjusted, a curing agent is added for curing to obtain a cured product, a cationic starch gelatinization solution is added to the cured product, and stirring is conducted uniformly to obtain a stirred product; one surface of antirust base paper is uniformly coated with the stirred product and dried, and the other surface of the dried paper is compounded with a reinforcing material to obtain the metal antirust paper.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a preparation method of slow-release metal antirust paper. Background technique [0002] Metal materials play a very important role in modern industry and agriculture. However, during the storage and circulation of metal parts, surface corrosion and oxidation often occur. Metal corrosion is a problem that has plagued people for a long time. It is mainly caused by electrochemical corrosion. Water, oxygen in the air, and some electrolytes on the metal surface are the main causes of metal corrosion. The loss caused by metal corrosion is extremely serious. According to the statistics of the American Institute of Metals, the global economic loss caused by metal corrosion accounts for 4% of the total production value every year, and the metal scrapped due to corrosion accounts for 30% of the total output. The economic loss of metals has reached more than 300 billion yuan, and me...
