て応えるかが本発明で検討した内容である。BACKGROUND OF THE INVENTION Painted flanges and painted plugs constitute the mouthpiece of a steel container, and in many cases refer to a steel inner can. Recently, as seen in steel 200L internal drums, the filling material has increased to include fine chemical products, and there are also components that peel off the paint film caused by the cap, and chips from the metal components that make up the cap. There are many requests to reduce this as much as possible. Therefore, the subject of the present invention is how to meet these demands.

粉が発生する。[0003] Here, we will discuss what problems arise from the aspect of the coating film due to the engagement of the threads of the coating flange and the coating plug. The problem is that when the cap is sealed, the flange, threaded part of the plug, and paint film are subjected to friction, causing the paint film to peel off and fall off. At the same time, large defects in the coating film occur, and the underlying metal becomes powder-like and falls off. In this case, when the plug is made of zinc die-casting, zinc chips are generated, and when the plug is made of steel and is made of unichrome plated (electrogalvanized), iron-zinc chips are generated.

It is based on the paint constituent resin component shown in No. 0725. However, the inventor of the present invention has found that a technical problem when using a combination of a painted flange and a plug with the paint shown in this invention is the problem of friction between the coated surfaces of the painted flange and the painted plug, and the present invention solves this problem. We have found a new use for the fact that by adopting this method, the amount of dust can be significantly reduced.

After tightening the cap tightly with a torque value of kgf cm, the cap was opened, and the amount of peeling of the paint film and metal chips (
The amount of dust (hereinafter referred to as dust amount) was measured. The amount of dust when the olefinic hydrocarbon was added was 0.20 mg/set, but when it was not added it was 1.2 mg/set. Further, when 0.5% to 3.0% of olefinic hydrocarbon was added, the amount of dust was 0.18 to 0.22 mg/set. The results are shown in Tables 1-1 and 1-2.

した。In Experiment 1-2, the amount of dust was investigated when the ratio of the resol phenol component to the average molecular weight of bisphenol was changed from 450 to 3,700. A resol phenol component was prepared using 50 parts each of a meta-cresol component and a para-cresol component, and then a polycondensation reaction was performed by changing the blending ratio of bisphenol with an average molecular weight of 450 to 3,700, and the resulting resin composition was used as a paint resin composition. . Next, a paint containing 1.5% of an olefinic hydrocarbon having the general formula CnH2n was applied to the threaded portion of the unichrome-plated steel flange and the unichrome-plated steel plug.

It becomes a problem. Therefore, a coating thickness of 2 to 8 microns was suitable for the flat part of the screw, and the best thickness was 5 microns.

The cap was tightened with a torque of kgf·cm, and then opened. The dust generated at that time was measured. As a variable factor in this case, an experiment was conducted in which the ratio of phenol content to epoxy content was varied. The obtained results are shown in Table 1-1 and Table 1-
As shown in 2, the study results in the range of phenol component:epoxy component ratio of 20 to 60:40 to 80 showed that the amount of dust was less than 0.2 mg/set, and the addition of olefinic hydrocarbons The results showed that the effect was significant.

It was confirmed that the amount of dust was significantly reduced by adding C38), and in Experiment 1-2, the ratio of resol phenol component to epoxy component was phenol:epoxy = 20-60:40-80. It was confirmed that the amount of dust could be reduced within this range.

This is because the olefinic hydrocarbon CnH2n (C31-C38) added to the paint enters the paint film, and the paint film itself has enough lubricating performance to prevent breakage caused by friction. It is believed that the composition of the paint film also gave good results, in addition to the fact that the coating film was resistant to breakage.

は１．２ｍｇ／組の量であった。[Example] Example 1 A coating resin having the general formula CnH2n was prepared by polycondensing 20 parts of methylolphenol resin consisting of 50 parts of meta-cresol and 50 parts of para-cresol with 30 parts of bisphenol A type epoxy resin (Epicoat 1007). Adding 1.0% of olefinic hydrocarbons with carbon numbers of 31 to 38, 5% is added to unichrome-plated steel flanges and plugs.
The coating was applied to a coating thickness of μ. Using this flange and plug, the plug was tightly closed with a tightening torque of 200 kgf·cm, and the amount of dust generated when the plug was opened was measured. In the case where olefinic hydrocarbon was added, the combined amount of dust was 0.18 mg/set, whereas in the case where olefinic hydrocarbon was not added, the amount was 1.2 mg/set.
