Problems solved by technology

The most commonly used anti-corrosion method is to coat the metal surface with anti-rust oil, but this method will lose efficacy due to oxidation of the anti-rust oil itself, and it is time-consuming and labor-intensive to remove the protective layer, which is neither hygienic nor safe
The use of desiccant to prevent rust is low in cost, simple in operation, safe and environmentally friendly, easy to remove protective packaging, but the effective time is short, and it is greatly affected by the ambient temperature
As for the packaging and processing of metal materials with special dehumidification equipment, although the anti-rust effect is good, the cost is high, time-consuming and labor-intensive, and the operation is complicated

Abstract

The invention discloses a vapor phase antirust blown polyethylene film and a making method thereof. The vapor phase antirust blown polyethylene film comprises low density polyethylene resin, a plasticizer, an auxiliary filler, sodium benzoate, cyclohexylamine phosphate, amine salt of aliphatic dibasic acid, and an antioxidant. Polyethylene materials comprising vapor phase antirust agents are utilized to make the vapor phase antirust blown polyethylene film through a blowing production process in order to realize convenient production and vapor phase antirust effects. The vapor phase antirust agents adopted in the invention are different from traditional nitrite vapor phase antirust agents, are in favor of realizing environmental protection and benefiting the health of human bodies. The film made in the invention has the advantages of composite structure, obstruction of the outward penetration of the vapor phase antirust agents, antirust effect increase and antirust time prolongation.

Description

technical field [0001] The invention relates to the field of gas-phase anti-rust, in particular to a polyethylene gas-phase anti-rust blown film and a preparation method thereof. Background technique [0002] Corrosion is a phenomenon in which metal materials and the surrounding environment are destroyed by chemical or electrochemical reactions. It is a reverse process of smelting. Natural environments and industrial media can cause corrosion of metal materials. In the process of transportation and storage of metals and their products, especially sea transportation and high-heat and humid land transportation, it is inevitable to involve rust prevention issues. The most commonly used anti-corrosion method is to coat the metal surface with anti-rust oil, but this method will lose efficacy due to oxidation of the anti-rust oil itself, and it is time-consuming and labor-intensive to remove the protective layer, which is neither hygienic nor safe. The use of desiccant for anti-r...
