であった。2. Description of the Related Art Conventionally, a low-temperature curable one-pack urethane paint used as an intermediate coating type anti-chipping paint for automobiles is obtained by curing a blocked polyisocyanate in which isocyanate groups are blocked with, for example, an oxime-based blocking agent, with a polyol. Although the film is formed by the reaction, the coating composition is heated and applied at about 30 ° C. in order to enhance the coatability since the viscosity of the coating composition is high. However, this coating composition does not have sufficient heat storage stability and its temperature needs to be controlled. In addition, when the oxime of the blocking agent dissociated at the time of curing volatilizes from the coating film, there is a problem that the surface of the film is roughened due to bumping or the like.

る。This high-thickness coating composition is a one-part urethane coating of a low-temperature curing type, in which a blocked polyisocyanate and a polyol are used as film-forming components, a filler and a solvent are added, and an acid and a phenol derivative are added. . Blocked polyisocyanate, which forms one of the film-forming components, is thermally dissociated into isocyanate groups and block compounds at a relatively low temperature, and isocyanate groups react with polyols having active hydrogen to form urethane bonds and cure. To form a coating film. This blocking agent has a molecular weight of 150 to 15
An alkylphenol-based compound of No. 00 is used. The alkylphenol having a molecular weight of 150 to 1500 has a molecular weight that does not cause bumping at the curing temperature of the coating film. If the molecular weight is less than 150, the limit thickness of the armpit decreases, which is not preferable. On the other hand, if the molecular weight exceeds 1500, the viscosity of the coating material becomes too high and handling becomes difficult, which is not preferable. Examples of the phenol include nonylphenol, octylphenol, and hexylphenol.
Are used. Since these alkyl phenols have a large molecular weight and do not scatter at once after dissociation due to heat, problems such as bumping do not occur on the film surface, and the limit film thickness can be improved. Examples of the blocked polyisocyanate include "Euroc, Q-9061, manufactured by Funny Kasei Co., Ltd."

きる。[0007] In order to maintain heat storage stability, this coating composition delays dissociation by adding an acid, mainly an organic acid.
The amount of the organic acid to be added is 0.05 to the solid content of the paint.
It is preferable to add in the range of 1.0% by weight. If the amount is less than 0.05% by weight, the storage stability is poor. As the organic acid, it is preferable to use the same organic acid as the component forming the coating film. For example, strong organic acids such as p-toluenesulfonic acid, benzenesulfonic acid, methanesulfonic acid, and chloroacetic acid can be used.

相溶性のあるものが使用できる。In order to maintain thermal stability, a phenol derivative may be added. This is a reversible equilibrium reaction of the block bond between phenol and isocyanate, and proceeds in the dissociation direction when the temperature increases. The reaction rate in the dissociation direction is reduced by the addition of the acid. However, this reaction is a reversible equilibrium reaction, and some isocyanates are dissociated and exist as free isocyanate groups.To suppress this, an excess amount of phenol in the blocking agent is used to bring the reversible equilibrium reaction to the bond side. Transfer to eliminate free isocyanate groups and improve heat storage stability. The above-mentioned object can be achieved by adding a phenol derivative having an affinity for a paint system without lowering the properties of the coating film. Since this phenol derivative increases the concentration of the phenol group, an effective phenol derivative is used in a small amount. For example,
Cresole, xylenol, ethyl phenol, propyl phenol, butyl phenol and the like which are compatible with the paint composition can be used.

If the addition amount is less than 0.05% by weight, the addition effect is not recognized, which is not preferable. On the other hand, if the addition amount exceeds 1.0% by weight, the properties are undesirably deteriorated. A one-pack type urethane coating obtained by blending an organic acid and a phenol derivative having good compatibility with the coating composition in a phenol-blocked polyisocyanate can provide heat storage stability, maintain low-temperature curability, and enable thick film coating.

できる。The low-temperature curable one-pack type urethane paint of the present invention contains a polyisocyanate blocked with an alkylphenol having a specific molecular weight, and contains a compatible acid and a phenol derivative in order to stabilize the block bond. I have.
The presence of the acid and the phenol derivative slows the dissociation of the block bond and acts on the reversible equilibrium reaction of the block bond in the direction of suppressing the dissociation, so that the heat storage stability of the coating composition is enhanced. Further, the added acid lowers the viscosity of the paint at the time of high shear, so that the paintability is improved and the paint can be applied at a low temperature. In addition, since the alkyl phenol as the blocking agent has a large molecular weight, it is possible to suppress occurrence of defects in the film surface appearance due to bumping or the like during volatilization.
