Rust-proof packaging corrugated carton

Abstract

The invention discloses a rust-proof packaging corrugated carton. The carton comprises a carton body, wherein the carton body comprises surface paper and corrugated boards; the carton body is formed by folding and splicing the corrugated boards; an antirust coating layer 3 is arranged on the inner surface of the carton body; a film coating layer is arranged on the outer surface of the carton body;the film coating layer is a waterproof coating layer; and the antirust coating of the antirust coating layer is prepared from the following substances in percentage by mass: 5-15% of a gas-phase antirust agent, 10-25% of a gas-phase volatile antirust agent, 2-5% of ethanol and the balance of methanol content. The antirust coating disclosed by the invention is coated on the inner paper of the carton through a coating means, and the used antirust coating has the advantages of a cationic antirust agent and the gas-phase volatile antirust agent; and the gas-phase volatile antirust agent is continuously volatilized to form antirust air masses in the carton to act on the product, so that rust stains are prevented from eroding contents, and the carton is more convenient for a user to use.

Description

technical field [0001] The invention relates to the technical field of corrugated cartons, in particular to a corrugated carton for antirust packaging. Background technique [0002] Our daily production and life are inseparable from steel materials, but the amount of steel lost due to corrosion every year in the world is huge. Therefore, how to protect metal products such as iron and steel from corrosion is of great significance. [0003] The corrosion process of steel products is a complex chemical reaction process. Rust is usually reddish brown, and different forms of rust will be generated under different conditions. Rust is mainly composed of iron oxide hydrate (Fe2O3 nH2O) and iron hydroxide [Fe(OH)3]. The rust structure on the surface of the steel is loose, which cannot hinder the contact of the iron inside with oxygen, water vapor, etc., eventually causing all the iron to rust. [0004] In the past, in order to prevent steel from rusting, we needed to isolate steel...

Problems solved by technology

In recent years, for mechanical and electrical products exported from European countries, the other party often requires oil-free anti-rust, because the anti-rust oil will eventually turn into sewage, which will cause pollution to the importing country.
