Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating material which is coated on a substrate such as metal, plastic or paper by using a roll (roll coater, reverse coater, DI can coater, gravure coater, etc.). Particularly, the present invention relates to a paint excellent in high-speed paintability.

[0002]

2. Description of the Related Art As a paint to be coated on a metal or the like by a roll coater, a reverse coater, etc., a thermosetting resin, a thermoplastic resin, a solvent such as an organic solvent or water, a pigment, an antifoaming agent, a lubricant or the like is added. Agent, usually about 75-80m / min with a roll coater, 100-150 with a reverse coater
m / min, and 800 to 1200 cans / min for a DI can coater.

However, when these various paints are used for high-speed coating, that is, 85-110 m / min for a roll coater, 150-200 m / min for a reverse coater, and 1200-1500 can / min for a DI can coater. In roll coaters and coaters for DI cans, flushing (paint becomes difficult to enter between rolls rotating at high speed,
There is a defect that the coating material is applied to the coating object without supplying the coating material to a part of the application roll, and a part of the coating material is not coated. Does not migrate to) occurs. Further, in the case of high-speed coating, the roll coater, the reverse coater, and the coater for DI can all suffer from misting (the paint is scattered when the paint is applied to the object to be coated and contaminates the object to be coated). Both flushing and misting are defects that significantly impair the value of the coated product as a coated product. In order to avoid flushing, in the past it was avoided by diluting the paint and lowering the viscosity of the paint, but misting becomes worse,
There is a drawback that varnish sagging occurs and the prescribed coating film amount cannot be secured.

[0004]

PROBLEM TO BE SOLVED BY THE INVENTION Even when high-speed coating is performed, a coating composition which does not reduce the coating viscosity or the coating thickness by using a diluent, has good flushing and is excellent in misting is provided. To do.

The above wax is (1) a method of heating and melting a wax and a solvent and dropping it into a cooled paint while stirring, and (2) a method of heating and melting a wax and a solvent and stirring in a cooled solvent. While adding dropwise to the paint, the one whose particle size has been adjusted with a disperser such as a sand mill is added to the paint, (3) a method in which wax powder finely pulverized to a desired particle size is added to the paint while stirring, (4) A wax powder finely pulverized to a desired particle size is dispersed in a coating film-forming resin and a solvent with a disperser such as a three-roll mill, and then uniformly added to the coating material by stirring. Can be added.

The size is 50% or less, preferably the average particle size is 1 to 10 μm, and the maximum particle size is 100% or less of the wet coating film thickness. Average particle size is 1μ
If it is smaller than m, the effect on flushing is small. Further, when the average particle diameter is 20 μm and the maximum particle diameter is not less than 150% of the wet coating film thickness, the appearance of the coating film is deteriorated. The wet coating thickness depends on the solid content,
It is usually about 2 to 3 times the dry coating thickness.

It is used in the range of 1 to 2% by weight. The form of the paint used in the present invention can be used for all paints applied using rolls such as solvent-based paints, water-soluble paints and water-dispersed paints.

Examples of the epoxy resin include those produced from epichlorohydrin and bisphenol A, those produced from epichlorohydrin and bisphenol F, and glycidyl esters synthesized from polybasic acid and epichlorohydrin. For example, Epicoat 1001, 1004, 1009, 1010 (made by Yuka Shell Epoxy Co., Ltd.), Epotote 7011, 7014,

(Manufactured by Ciba Geigy) and the like, and these are dissolved in a solvent and used. As the amino resin, a melamine resin, a benzoguanamine resin, a melamine / benzoguanamine resin, a urea resin, a glycoluril resin and modified resins thereof may be used alone or in combination. Examples of phenolic resins include carboxylic acid, o-cresol, m-cresol,

A reaction product obtained by polymerization can be used. Polyester resins include condensation of polybasic acids such as phthalic anhydride, isophthalic acid, terephthalic acid, trimellitic acid, adipic acid and sebacic acid with polyhydric alcohols such as ethylene glycol, neopentyl glycol and 1,6-hexanediol. The reaction product obtained by the reaction can be used.

As the self-curing acrylic resin, an addition polymer of the above acrylic monomer and a self-curing monomer such as N-methylol acrylamide can be used.

The paint used in the present invention comprises at least a film-forming resin, a wax and a solvent dispersed in the film-forming resin, and as the solvent, a solvent which has been conventionally used for paints is used. Aromatic, aliphatic,
Solvents such as alcohols, ketones, esters, ethers and water are used. The coating material thus produced may be used as it is, or may be used in combination with an auxiliary agent such as a lubricant, an antifoaming agent, a curing accelerator (catalyst), a leveling agent, an anti-UV agent or a plasticizer. An auxiliary agent and a coloring agent such as a pigment or a dye may be used in combination and used as a colored coating material.

The paint having the above-mentioned constitution is a size coat (base coat) for directly coating a work such as metal or paper,
Also, it can be used as an intermediate coating paint to be applied on a size coat, a direct coating on an object to be coated, a size coat, or a top coat to be applied on an intermediate paint. These paints are applied via rolls. For example, when the object to be coated is a metal plate, it is coated using a natural coater or reverse coater, and when the object to be coated is a can, it is coated with a dedicated coater. Ultimately, these coaters control the coating thickness by adjusting the gap (nip) between the two metal rolls and then the rubber application roll in contact with one of the metal rolls. It is painted. When coating with these coating machines, paint that does not contain wax dispersed in granules becomes more difficult to enter between the nips as the coating speed increases, and the paint was applied to the metal roll that is in contact with the application roll. A part and a non-applied part occur, and a part to which the paint is not applied is one of the causes of flushing.However, in the paint according to the present invention, turbulent flow is caused by the wax dispersed in the paint in a granular manner, The physical action makes it easier for the paint to enter between the nips, making flushing less likely to occur.

Further, in the case of a paint containing no wax dispersed in a granular form, the transfer surface becomes nonuniform when the paint is transferred from the metal roll to the application roll, and when it is transferred from the application roll to the object to be coated, which also causes flushing. In the coating material according to the present invention, the wax dispersed in the coating material in a granular form due to the pressure of the metal roll / application roll and the pressure of the application roll / material to be coated causes the metal roll / application roll central portion and the application roll. / Because it is oriented to the central portion of the object to be coated and is divided and transferred from the central portion of the wet coating film, flushing is less likely to occur. Furthermore, when the coating material is transferred from the metal roll to the application roll, the wet coating film is divided and transferred when the coating material is transferred from the application roll to the object to be coated, but the wet coating film is not formed when the coating material does not contain the wax dispersed in particles. When splitting, a thread leakage phenomenon occurs, and this thread leakage is shaken off by the centrifugal force of the roll to contaminate the coating plate and cause a misting phenomenon.However, in the coating material according to the present invention, it is dispersed in the coating material in a granular form. By aligning the wax in the center of the wet coating, the thread leakage phenomenon is less likely to occur when the wet coating is divided, and the misting phenomenon is less likely to occur.
