あるフィルム等で別途密封包装する必要がある。(Background of the Invention) When metal products such as mechanical parts get rusted during transportation and storage, they not only deteriorate in appearance but also lose their commercial value due to one dimensional error or loss of conductivity. As a countermeasure, methods have been adopted such as applying anti-rust oil to the parts and wrapping the parts in volatile anti-rust paper.However, parts coated with anti-rust oil must be cleaned before use. Therefore, an extra process is required.Also, with volatile rust-proof paper,
Since the product itself does not have a sealing function, it is necessary to separately seal and package it with a barrier film or the like to prevent the volatile rust preventive from diffusing into the surrounding area.
そこで今日では、熱可塑性樹脂に気化性防錆剤を含ませ
てこのものを溶融押出しして製造する気化性防錆フィル
ムの開発が行なわれている。Therefore, today, a volatile rust preventive film is being developed which is manufactured by melt-extruding a thermoplastic resin containing a volatile rust preventive agent.

り、しかもヒートシール性に優れた気化性防錆フィルム
を製造するのは困難であった。However, although this volatile antirust film is excellent in that it has a sealing function by itself when heat-sealed, those produced by melt extrusion have the following problems. That is, in the case of a single film of thermoplastic resin containing a volatile rust preventive agent (V) as shown in FIG. As a result, the anti-corrosion performance cannot be fully demonstrated, and the vaporizability disclosed in JP-A-48-15971 as shown in Fig. 2 (b) is unavoidable. The anti-corrosion film is a two-layer film consisting of a thermoplastic resin layer P containing a volatile rust preventive agent and a layer P' consisting only of thermoplastic resin. At the time of melt extrusion molding, the high temperature applied during melt extrusion molding causes the volatile rust inhibitor to vaporize and escape during the manufacturing stage.
It has the disadvantage of causing coloring, etc. Furthermore, JP-A-49
As shown in Figure 2(c), Japanese Patent Publication No. 1644 discloses a layer P consisting of a layer P of a low melting point thermoplastic resin containing a volatile rust preventive agent V, and a layer P consisting only of a high melting point thermoplastic resin. A vaporizable antirust film in the form of a layered film is disclosed. However, even if a low melting point resin is used in this way, the resin will still be melted during the extrusion process. Therefore, only volatile rust inhibitors with low vapor pressure that can withstand the melting temperature can be used, and in actual rust prevention. At room temperature, where functionality is required, only volatile rust-preventing films with slow vaporization rates and low rust-preventing ability can be obtained.
Therefore, even the production method using melt extrusion still has its limitations, and it is difficult to produce a volatile rust-preventing film that has high rust-preventing ability, long-lasting power, and excellent heat-sealability. Met.
このように従来十分な防錆性能を発揮する製品ができな

た製造手法を採るときには、より防錆性能の優れた製品
を得られるであろうとの着眼は、例えば特開昭５１−３
９７８４号に開示されているように既になされている。One of the reasons why it has not been possible to produce products that exhibit sufficient rust prevention performance is that the thermoplastic resin containing the volatile rust preventive agent must be heated during manufacturing. Therefore, when adopting a manufacturing method based on a coating method that does not require heating, it is possible to obtain a product with better rust prevention performance.
This has already been done as disclosed in No. 9784.

られるかが解明されておらず未だ着想の域にとどまり、
実用可能な製品は開発されていない。However, because the requirements in terms of rust prevention performance have not been so strict in the market, no further attempts have been made to elucidate this coating method. For this reason, it is not clear exactly what kind of characteristics a volatile rust preventive agent has to be used to obtain a volatile rust preventive film with excellent rust prevention effects, and it remains in the realm of ideas.
No practical product has been developed.

試みたものである。<Technical matters attempted to be developed> The present invention was made in view of the above background, and
Based on the premise of adopting a coating method that has not been subject to practical technical investigation, we have established various conditions for the volatile rust preventive film produced using this coating method to have good rust preventive effects and heat sealability. In addition to investigating these conditions, we attempted to develop a volatile rust-preventing film that has excellent rust-preventing effects and heat-sealing properties, as well as a method for producing the same.

より。In addition to various single films such as EEA, EAA, and EVA, composites of the above films may be used in consideration of strength. Also, in the case of a volatile rust preventive film, the vaporized rust preventive agent in particular escapes to the outside air. Since it is important to prevent corrosion from occurring in order to improve the rust prevention effect, it is possible to use an aluminum vapor-deposited version of the above-mentioned film having high gas barrier properties, or a composite of aluminum foil and the above-mentioned film. Furthermore, when packaging heavy items, use cloth, resin cloth, etc. to increase the strength of the film.
It is preferable to use a composite of split fabric, nonwoven fabric, etc. and the above-mentioned film, depending on the object to be packaged, usage, cost, etc.
ＰＥ、ＰＰ、ＥＶＡ等のラミネート品等を適宜選択して
使用することができる。A laminate product such as PE, PP, EVA, etc. can be appropriately selected and used.
次に本発明に使用する熱可塑性樹脂は、基材に塗布乾燥
した皮膜が常温で粘着性を有さず、融点が１２０〜ｉｓ
ｏ”ｃであるものを使用する。Next, the thermoplastic resin used in the present invention has a film that is coated and dried on a base material, has no tackiness at room temperature, and has a melting point of 120-IS.
o"c is used.
因みに熱可塑性樹脂の融点をこのような範囲のものとし
た理由は以下のとおりである。即ちたとえ同じ樹脂であ
っても、加熱溶融により得られた皮膜に比較して、塗布
乾燥により得られた皮膜はブロッキングしやすい、これ
は熱可塑性樹脂の有機溶媒溶液、エマルジョン液を塗布
した場合、溶媒を完全に除去することは理論的には可能
であるが、加工性が大幅に低下するため事実上は困難な
場合が多く、皮膜に多少とも溶媒が残留するためである
と考えられる。このためブロッキングを防止することを
目的として。Incidentally, the reason why the melting point of the thermoplastic resin is set in such a range is as follows. In other words, even if the resin is the same, a film obtained by coating and drying is more likely to block than a film obtained by heating and melting.This is because when an organic solvent solution or emulsion liquid of a thermoplastic resin is applied, Although it is theoretically possible to completely remove the solvent, it is often difficult in practice because the processability is significantly reduced, and this is thought to be because some solvent remains in the film. For this reason, the purpose is to prevent blocking.
ブロッキング防止剤、滑剤、スリップ剤等の添加が行な
われているが、融点が１２０℃以下の熱可塑性樹脂を使
用した場合には１袋での流通時にブロッキングの危険性
が大きい、また逆に。Anti-blocking agents, lubricants, slip agents, etc. are added, but if a thermoplastic resin with a melting point of 120°C or lower is used, there is a great risk of blocking when distributed in one bag, and vice versa.
使用した気化性防錆剤の融点より２０〜３０°Ｃ以上高
い温度でヒートシールを行なうと、熱可塑性樹脂中の気
化性防錆剤が発泡し、ヒートシール力が低下するととも
に外観不良ともなる。If heat sealing is performed at a temperature 20 to 30°C higher than the melting point of the volatile rust preventive agent used, the volatile rust preventive agent in the thermoplastic resin will foam, reducing the heat sealing power and causing poor appearance. .
そこで後述するように使用する気化性防錆剤の融点の上
限が１５０℃であるため、ヒートシール温度は１８０℃
以下で行なわなければならず。Therefore, as described later, the upper limit of the melting point of the volatile rust preventive used is 150°C, so the heat sealing temperature is 180°C.
You must do the following.
融点が１８０℃以下の熱可塑性樹脂を使用しなければな
らない、具体的にはアクリル系樹脂、塩酢ビ系樹脂、変
性ナイロン樹脂、ポリエステル系樹脂、ポリウレタン系
樹脂、酢酸ビニル樹脂等から融点１２０〜１８０℃のも
のを選択して使用する。A thermoplastic resin with a melting point of 180°C or less must be used. Specifically, a thermoplastic resin with a melting point of 120°C or less must be used, such as acrylic resin, salt vinyl acetate resin, modified nylon resin, polyester resin, polyurethane resin, vinyl acetate resin, etc. Select and use one with a temperature of 180°C.
次に本発明に使用する気化性防錆剤について説明する。Next, the volatile rust preventive used in the present invention will be explained.
まず気化性防錆剤は常温で固体のものを使用する。これ

らである。また気化性防錆剤は熱可塑性樹脂に対し相溶
性がないことが必要である。First, use a volatile rust inhibitor that is solid at room temperature. This is to uniformly disperse the volatile rust preventive agent in the organic solvent solution or emulsion of the thermoplastic resin. That is,
If the volatile rust preventive agent is not uniformly dispersed, the coating surface will be uneven when the dispersion is applied to the base material, making it impossible to perform a good heat seal. When a rust agent is used, as will be described later, a vaporizable rust preventive agent that is compatible with the thermoplastic resin is not used, so a liquid vaporizable rust preventive agent is present in the thermoplastic resin layer. This is because when pressure is applied, a problem arises in that the volatile rust preventive agent easily leaches onto the surface of the thermoplastic resin. Further, it is necessary that the volatile rust preventive agent is not compatible with the thermoplastic resin.

える影響が大きく、相溶性がない場合と比較して、同じ
ヒートシール性を得るためには熱可塑性樹脂の塗布量を
より多くしなければならず、経済的でないからである。This means that when the volatile rust preventive agent is compatible with the thermoplastic resin, it has a large effect on the reduction in heat sealing properties of the volatile rust preventive agent, and compared to when it is not compatible, it is the same. This is because in order to obtain heat-sealability, the amount of thermoplastic resin applied must be increased, which is not economical.

。Further, in the present invention, the vapor pressure at 20°C is 0.0005 to 0.
05+++ ■Hg, a volatile rust preventive agent with a melting point of 90°C to 150°C is used. This is because when 5 to 30% of a volatile rust inhibitor is dispersed in a thermoplastic resin, the vaporization rate becomes significantly slower than that of the volatile rust inhibitor alone. 0.00 to obtain a sufficient vaporization rate.
This is because it is necessary to use a volatile rust preventive agent with a vapor pressure of 0.5w+dg or higher. If 0.0005a+mH
When using a volatile rust preventive agent with a vapor pressure of less than g, the vaporization rate is slow, so there is a high risk that the packaging vaporizable rust preventive agent will evaporate and rust will occur before it becomes effective. It cannot be a practical anti-rust film; on the contrary, the vapor pressure is 0°05m+
When using a volatile rust preventive with nHg or higher, the vaporization rate is very fast, so the volatile rust preventive may evaporate and disappear during the production or use of the volatile rust preventive film.
A problem arises in that the volatile rust preventive agent evaporates from the volatile rust preventive film and precipitates again during distribution and inventory. In addition, products using such volatile rust preventives with high vapor pressure have a short duration of rust preventive effect and are not suitable for practical use. The reason why the temperature was set at 150°C is as follows. That is, in the present invention, the melting point is 1
A thermoplastic resin having a temperature of 20 to 180"C is used, but the sealing temperature in this case must be 110 to 120"C or higher.
もし融点が９０°Ｃ以下の気化性防錆剤を使用した場合

性防錆剤の平均粒径は５０μ以下。On the other hand, volatile rust inhibitors with a melting point of 150°C or higher,
Since the vapor pressure is low, the vaporization rate is slow, and a practical product cannot be obtained.Incidentally, the characteristic idea of the present invention is to limit the vapor pressure and melting point of the volatile rust preventive agent to a certain range. Only within such a limited range can a suitable vaporization rate of the volatile rust preventive agent be obtained, and a volatile rust preventive film with excellent heat sealability. The average particle size of the volatile rust preventive agent is 50μ or less.

Incidentally, if the average particle size and maximum particle size of the volatile rust inhibitor exceed these values, the particles will get caught in the coating area of the roll coater (represented by S in Figure 1) and streaks will occur, resulting in a thin, uniform coating. Unable to obtain coating film.

First, the thermoplastic resin 1a is dissolved or suspended in an organic solvent 2, and the volatile rust preventive agent 3 is added and dispersed therein at a ratio of 5 to 30% by weight based on the thermoplastic resin 1a to create a dispersion liquid 4. do. Incidentally, if the amount of the volatile rust preventive agent 3 added is less than 5% by weight, sufficient rust prevention ability will not be obtained, and if it is more than 30% by weight, it will affect the heat sealability of the zero-order base material 5 and the thermoplastic. In order to improve the bonding with the resin 1a, an adhesive is applied to the base material 5 to form an adhesive layer 6. Of course, if the combination of the base material 5 and the thermoplastic resin 1a allows good bonding between the two, the adhesive layer 6 may not be provided. The resin 1a is applied at a rate of 5 to 40 g per 1 m' using a roll coater R or a sprayer, and this is heated and dried in a sealed atmosphere of a tunnel drying furnace T to form a volatile rust preventive film.
