Description

Anticorrosive resin pallet for packaging and antirust film using same and manufacturing method thereof {Anticorrosive resin pellet and Anticorrosive film using the same}

The present invention relates to a packaging resin pallet for improved rust prevention performance, and to a rust preventive film using the same, and to a method of manufacturing the same. More specifically, to a corrosion-resistant film or sheet resin composition suitable for corrosive metals or other packaging, prepared by the resin composition To a film and a method for producing the same.

In general, water and oxygen occupy more than 70% of the corrosion of metal, and when the temperature drops from 50% relative humidity in the air, the water molecules in the air become cold and turn into water droplets. When the water droplets adhere to the metal surface, an unbalanced electric potential is generated on the metal surface, causing an electrochemical reaction to form rust.

Therefore, in order to prevent corrosion of such metals, there is a method of preventing corrosion by inhibiting the generation of an unbalanced dislocation occurring on the surface of the metal and suppressing an electrochemical reaction. This is because of the limitation of use, that is, the increase of the labor and the cleaning after use due to the application of rust preventive oil or rust preventive agent, it may cause the problem of environmental pollution after cleaning, and the effect of rust prevention cannot last for a long time. It is not desirable. Therefore, in order to compensate for such drawbacks, the use of vaporizing rust inhibitors has been greatly increased, and the amount of use thereof is also increasing. However, conventionally used vaporizing rust inhibitors include dicyclohexyl ammonium nitrite, diisopropylamine nitrite, and the like, which may cause environmental pollution or their carcinogenic properties. The use of the substances defined by the substance had the effect of rust prevention, but most of them have a great effect on the environment and the human body, and their use is not desirable, and their use is regulated in other countries such as Europe, the United States, and Japan. There is a problem in that it is impossible to use or export packaging of products using the same, and thus cannot be used practically.

Accordingly, the present invention is to solve the above-mentioned conventional problems is an object of the present invention to prevent corrosion of the product during the packaging of metal products or non-ferrous metals and excellent packaging effect of the anti-corrosive effect of metals or non-ferrous metals without the use of anti-rust oil or To provide an antirust resin pallet and a film using the same.

Another object of the present invention is to provide an embossed packaging anticorrosive resin pallet having a much larger surface area of an anticorrosive agent vaporized than a conventional rustproof film and a film using the same.

The object of the present invention is to impregnate a polyolefin resin or a thermoplastic resin, more specifically a polyethylene resin for the anticorrosive or anti-corrosion of a metal product or non-ferrous metal to prepare a vaporizable anti-rust resin pallet and thus prepared vaporization The anticorrosive resin pallet is used alone or in combination with a thermoplastic resin, preferably a low density polyethylene resin or a linear low density polyethylene resin, to prepare a vaporizable antirust film, and the film is embossed to increase the surface area to be vaporized. By increasing the cross-sectional area it was achieved by making the performance of the rust preventive very excellent.

Packaging antirust resin pallet of the present invention for achieving the above object;

Vaporizable mixture of 2.0-20.0 wt% of benzotriazole compound, 5.0-15.0 wt% of nitrite metal compound, 5.0-20.0 wt% of acetate or benzoate metal compound at room temperature Methylene bis stearamide, ethylene bis stearamide, ethylene bis stearamide or oleic acid amide and stearic acid, which are widely used as a dispersant by mixing rust preventive powder and 45.0 to 70.0% by weight of polyethylene resin in this compound. One or more of amide (octadecanamide) and erucamide are mixed and mixed again by 1.0-8.0% by weight and 0.05-2.0% by weight of zinc stearate. Characterized by obtaining a vaporizable anti-rust resin pallet.

According to another configuration of the present invention, the mixture of the vaporized rustproof resin pallet prepared as described above to 2.0 to 15.0% by weight in a polyethylene film, and then mixed by extrusion extrusion resin to obtain a vapor-proof rustproof film excellent in rust resistance It is characterized by.

In the case of the vaporizable rustproof film produced according to the configuration of the present invention, the same rust prevention effect as iron or non-ferrous, and the film thus produced by a known embossing treatment method, for example, the method described in Patent Application No. 2001-0107366 By embossing, the unit surface area of the film is increased to increase the dispersion amount of the vaporizable rust preventive agent.

Preferably 55.0-65.0 weight% of said polyethylene resin can be used.

Stearamide compounds widely used as the dispersant used according to the configuration of the present invention is preferably oleic acid amide, stearic acid amide, erucamide, methylene bis stearamide, ethylene bis stearamide preferably 3.0 -6.0 weight% can be used.

The zinc straight is preferably 0.2 to 1.0% by weight.

The vaporized rustproof resin pallet product prepared as described above is mixed and mixed in a polyethylene film to be 2.0 to 15.0% by weight, and then the resin is extruded to produce a vaporizable rustproof film having excellent rust resistance. It has the same rust prevention effect on nonferrous metals and nonferrous metals. Especially, it has excellent rust prevention effect on nonferrous metals such as copper. Furthermore, by embossing the film thus manufactured, it increases the unit surface area of the film and increases the amount of vaporizing rust inhibitors. There is an advantage to it.
