Embodiment 1

[0023] Take 0.25 kg of cyclohexylamine, 0.25 kg of dicyclohexylamine, 0.12 kg of benzoic acid, and 0.35 kg of p-tert-butylbenzoic acid, mix and grind, add 5.3 kg of low-density polyethylene, and granulate by twin-screw at 150-180°C Machine or mixer for granulation to make gas-phase anti-rust masterbatch; then mix with 23 kg of low-density polyethylene and 38 kg of linear low-density polyethylene, and make gas-phase anti-rust membrane.

Embodiment 2

[0025]Mix and grind 0.25 kg of cyclohexylamine, 0.25 kg of dicyclohexylamine, 0.12 kg of benzoic acid, 0.35 kg of p-tert-butylbenzoic acid, and 0.75 kg of cinnamic acid, add 8 kg of low-density polyethylene, and heat at 150~180°C Granulate through a twin-screw granulator or a mixer to make a gas-phase anti-rust masterbatch; then mix it with 25 kg of low-density polyethylene, 38 kg of linear low-density polyethylene, and 0.01 kg of oleic acid amide, and pass through the blown film unit Make vapor phase antirust film at 180~200℃.

Embodiment 3

[0027] Take 0.35 kg of morpholine, 0.25 kg of cyclohexylamine, 0.25 kg of dicyclohexylamine, 0.12 kg of benzoic acid, and 0.35 kg of p-tert-butylbenzoic acid, mix and pulverize them, add 5.9 kg of low-density polyethylene, and heat at 150~180°C Granulate with a twin-screw granulator or a mixer to make a gas-phase anti-rust masterbatch; then mix it with 23 kg of low-density polyethylene, 38 kg of linear low-density polyethylene, 0.01 kg of oleic acid amide, and the diffusing agent EB-FF Mix 0.01 kg, and make a gas phase anti-rust film at 180~200°C by a film blowing unit.

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 can be 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. Chinese patent 01127534.0 discloses a gasification anti-rust film ...
