Abstract

The invention discloses a preparation method of damp-proof slow-release antirust paper, and belongs to the technical field of antirust paper preparation. Limestone water is used for neutralizing and precipitating calcium phytic acid from broad beans, the calcium phytic acid and pomegranate peels are subjected to the action of active microorganisms in rottenwood to obtain a mixed fermentation solution containing phytic acid and tannin, in addition, the tannin can be bound with protein in a protein adhesive to generate a dense, flexible and impermeable leather layer not likely to decay; proteinis extracted from soybeans to be subjected to acid heat modification, the soybean protein molecular chains are extended, the soybean protein is subjected to alkali modification under the high concentration of a sodium hydroxide solution, some soybean proteins are subjected to hydrolysis, p-nitrophenol and the alkali protein adhesive react to generate sodium para-nitrophenolate, the sodium para-nitrophenolate can be gasified, a layer of special complex is generated on the surface of metal through a rust-proof inner film, particles of the PET film can be distributed and loosened in the gasification process of the sodium para-nitrophenolate, a gas-phase corrosion inhibitor can be slowly released, and the application prospect is wide.

Description

technical field [0001] The invention discloses a preparation method of moisture-proof slow-release anti-rust paper, which belongs to the technical field of anti-rust paper preparation. Background technique [0002] As the name suggests, antirust paper is a paper material used to prevent metal from rusting. The base material is usually kraft paper for packaging. Rustoper (corrosion terminator) vapor phase antirust paper is made of high-quality antirust base paper and efficient compound special VCILIQUID, which is processed and refined by special technology. The traditional antirust paper is mainly contact type, that is, only the antirust paper can play the role of antirust in direct contact with the metal surface, which has great limitations in actual use. Later, vapor phase antirust paper appeared. The VCI anti-rust agent contained in the high-quality material volatilizes naturally, no matter whether the vapor phase anti-rust paper is in contact with the metal surface, it c...
