(Industrial Application Field) The present invention relates to a container having water- and oil-repellent properties for containing various solutions such as ink, cosmetic liquid, and paint. (Prior art and its problems) Generally, in order to check the remaining amount of various solutions such as ink contained in a container, it is necessary to use a highly transparent material for the container or provide a viewing window. It is possible to accomplish that goal from the outside with the naked eye. However, even if the container is made of a highly transparent material, there is a problem in that the solution itself tends to adhere and remain on the inner surface of the container, making it often difficult to confirm the remaining amount of the solution. Conventionally, in order to solve this problem, it is known that the inner surface of the container is coated with a fluorine-based resin, but in this case, the fluorine-based resin itself is milky white, so it is not transparent. There are some problems, and since high heat is applied when curing the coated fluorocarbon resin, resin products cannot be used and there are restrictions on the material selection of the container.Furthermore, fluorocarbon resin Since it is non-adhesive, there remains a problem in its adhesion to the container. In addition, if the solution stored in this container contains a solvent such as xylene, if there are pinholes in the coated fluorine-based resin film, the gas permeability is high and the problem may occur over time. There have been many problems, particularly in the case of resin containers, such as a decrease in water and oil repellency and the possibility of peeling of the fluorine-based resin film. In addition, in order to solve the above-mentioned transparency problem and problems associated with heat treatment during curing, it is possible to use a chromium-based coupling agent, which is known as a waterproofing and sizing agent for textiles and paper. However, in the case of a synthetic resin, there was a problem in that it was difficult to obtain a strong film on the inner surface. (Object of the invention) The present invention has been made to eliminate the conventional problems with resin containers, is low cost,
In addition, in order to easily obtain a container with excellent water and oil repellency, this product was finally completed as a result of extensive research into various film-forming materials exhibiting water and oil repellency. (Structure of the Invention) That is, the present invention provides water and oil repellency by forming a coating with a chromium-based coupling agent on the inner surface of a transparent or translucent resin container containing various liquids, the inner surface of which has been treated to be hydrophilic. The gist is a container with functions. In the present invention, in particular, since a coating with a chromium-based coupling agent is formed on the inner surface of the resin container whose inner surface has been treated to be hydrophilic, the chromium-based coupling agent is applied to the OH groups and COOH groups located on the inner surface of the resin container.
It forms stable covalent bonds with groups such as chromium-based coupling agents, SH groups, NH groups, SO 3 H groups, etc., and a monomolecular polymer film is formed on the outermost surface by the chromium-based coupling agent. The presence of fatty acids in each molecule of the chromium-based coupling agent, such as capric acid, lauric acid, myristic acid, palmitic acid, margaric acid, and stearic acid, on the outermost layer of the membrane provides stability that has not been seen previously. Moreover, it is presumed that a container with excellent water- and oil-repellent properties can be obtained. The present invention will be explained in detail below. The chromium-based coupling agent used in the present invention is Chiron S (Tetrachloro-μ-hydroxy [μ-
(octadecanoato−0:0′)]−dichromium,
C 18 H 36 Cl 4 Cr 2 O 3 ), Chiron M (Tetrachloro-μ-hydroxy [μ-
(tetradecanoato−0:0′)]−dichromium,
C 14 H 28 Cl 4 Cr 2 O 3 ), Chiron C (Pentahydroxy (tetradecanoato) di
-chromium, C14H32Cl4Cr2O7 ) , borane ( Tetrachloro -μ- hydroxy [μ-(2-methyl
−2−propenoato−0:0′)]−dichromium,
C 4 H 6 Cl 4 Cr 2 O 3 ), Borane L (compared to borane, the amount of residual Cl is smaller, other things are the same as borane) (DuPont
Co., Ltd.), and these include water, methanol, ethanol, isopropyl alcohol, benzene, toluene, methyl ethyl ketone,
They are used singly or in combination of two or more of them dissolved in a solvent such as n-hexane, trichlorethylene, triflon, carbon tetrachloride, perchloroethylene, and other ethers and esters. The blending ratio of this chromium-based coupling agent is based on the total amount of solution.
It is preferably 0.01 to 20% by weight; if it exceeds 20% by weight, the effect will not change much, and if it is less than 0.01% by weight, the effect will not be expected to be much. Further, the pH value of this chromium-based coupling agent solution is preferably in an acidic range to a neutral range in order to stabilize the pH value. PH
This is because if the value is on the alkaline side, precipitation of the chromium-based coupling agent may occur. Therefore, when adjusting the pH of the chromium-based coupling agent solution, the pH may be set within the above range using sodium hydroxide, potassium hydroxide, ammonia water, hexamethylenetetramine, or the like. Next, the resin container used in the present invention basically has transparency or translucency from the viewpoint of confirming the remaining amount of contents, and
Those with excellent chemical resistance are suitable, and specific examples include polyethylene terephthalate, polyethylene, polypropylene, vinyl chloride, transparent nylon, and the like. A container formed into an appropriate shape from these materials is immersed in a solution containing the aforementioned chromium-based coupling agent to provide a treatment layer on at least the inner surface of the container, and then undergoes a drying process to form the desired container. Although it is easy to obtain, the important thing is that the inner surface of the container is subjected to a surface treatment to make it hydrophilic before treatment with the chromium-based coupling agent. In the present invention, various colloidal solutions such as alumina and silica may be used in conjunction with the coating treatment with the chromium-based coupling agent. Specifically, the surface treatment, which is a hydrophilic treatment, is performed to improve the adhesion of the chromium-based coupling agent to the inner surface of the container.
Etching treatment with chromic acid, treatment with various silane coupling agents, or a combination of these various treatments can be performed. (Examples) The present invention will be explained in more detail below using examples. Example After cleaning a cylindrical translucent polypropylene container with an inner diameter of 2 cm and a height of 10 cm with isopropyl alcohol, the inner surface of the container was washed with an aqueous solution of 300 g/l sulfuric acid and 400 g/l chromic acid at 70°C. Then, the container is treated by immersing it in a 1% by weight aqueous solution of a chromium-based coupling agent (Kilon C, manufactured by Dupont Co., Ltd.) with a pH of 4 (adjusted with hexamethylenetetramine) using isopropyl alcohol. A translucent container was obtained by heating and drying with hot air at 60°C for 30 minutes. Comparative Examples 1 and 2 Polypropylene containers of the same shape as those in the examples were prepared and simply washed with neutral cleaning.
Moreover, Comparative Example 2 was obtained by not performing the etching treatment in the Examples. (Effects of the Invention) Each of the containers obtained in Examples and Comparison Rows 1 and 2 was filled with one-third of the ink having the following composition, and the containers were shaken from side to side to form the ink containers at that time. The adhesion state and contact angle were measured. The results are shown in the table below.

Since the material was resin and high-temperature heat could not be applied, the adhesion of the film could not be improved, so it could not be put to practical use. As can be seen from the above explanation, according to the present invention,
The inner surface of the transparent or translucent resin container, which has been treated to be hydrophilic, is coated with a chromium-based coupling agent, making it easy to store various solutions in this container and check the remaining amount before use. By being able to prevent the solution from adhering and remaining on the inner surface of the container as much as possible, the determination can be made quickly and reliably by visual inspection, making the container particularly useful. Furthermore, since the film treated with the chromium-based coupling agent in the present invention is hydrophilized as a base treatment, it firmly adheres to the inner surface of the resin container, and as a result, it is stable over time. The intended purpose can be fully achieved and it can be used in a wide range of fields such as various industrial containers.
