Gas-phase anti-rust composite packaging film for industry and preparation method thereof

Abstract

The invention relates to a rust proofing packaging film, in particular to a gas phase rust proofing industrial composite packaging film and a preparation method thereof. The gas phase rust proofing industrial composite packaging film comprises the compositions by weight proportion: 0 to 0.53 of drewamine, 0.12 to 0.42 of cyclohexane, 0.13 to 0.4 of dicyclohexylamine, 0.09 to 0.28 of phenylformic acid, 0.22 to 0.55 of tert-Butyl benzoic acid, 0 to 0.12 of cinnamylate, 29.5 to 45.1 of low density polyethylente, 29.5 to 45.1 of linear low density polyethylene, 0 to 0.02 of oleamide or erucyl amide and 0 to 0.12 of a diffusing impurity EB-FF. The gas phase rust proofing film has good barrier property and high intensity, saves cost, is nonpoisonous and harmless, prevents the pollution, and canbe reused. The preparation method is simple and convenient, the process is easy to control and the production cost is low.

Description

technical field [0001] The invention relates to an antirust packaging film, in particular to a gas phase antirust industrial composite packaging film and a preparation method thereof. Background technique [0002] At present, the commonly used anti-rust methods include anti-rust liquid and anti-rust oil. This method requires cleaning and soaking of the protected articles, or special equipment such as spraying and sprinkling, and is harmful to polyethylene and other products. impact and cause environmental pollution. Vacuum packaging can also prevent rust, but expensive packaging equipment is required, and it is easily damaged during transportation. It cannot be packaged for large-volume products, and the cost is too high. Higher packaging technology is required. The widely used paper-plastic composite vapor phase antirust paper has poor barrier properties, low strength, and is not suitable for repeated use.
