る。2. Description of the Related Art Conventionally, when an old coating film is peeled off for repainting an outer wall of a building or the like, a peeling agent has been used to shorten the time required for the peeling operation. This release agent contains methylene chloride as a main component, and by leaving it for several tens of minutes after application, the release time can be greatly reduced. However, methylene chloride has problems such as causing environmental pollution, and is likely to be banned in the near future. For this reason, the cost is greatly increased among companies with high environmental awareness. However, there are cases where the peeling operation is performed only by the physical force of the high-pressure washing machine without using a peeling agent.

うな用途にしか使われていない。[0003] When a conventional organic solvent-based release agent is used for the outer wall, the release agent slides down because it dissolves the coating film surface. Further, the dissolved coating film is in the same state as the paint before drying, and the overall work efficiency, such as the application efficiency of the release agent, the re-adhesion to the work place, and the disposal of the paint, is significantly reduced.
For this reason, although it is still partially used as a peeling agent for the outer wall, it is generally used only for applications such as immersion in a peeling agent in a factory operation or the like.

Mixtures of di- and tri-propylene glycol monoalkyl ethers, unreacted substances and the like can be used for cost reduction. The same applies to those obtained by dialkyl etherification. On the other hand, as the glycol ether of the above-mentioned main component, one having a weak coating film dissolving power is selected, but in order to increase the swelling power and the softening power of the coating film, it is preferable to add a penetration enhancer that increases the permeability to the coating film. . Organic solvents that can be used as penetration enhancers include NMP, esters,
Ketones and alcohols are widely used, but NMP and dibasic acid esters such as dimethyl adipate and dimethyl succinate are desirable from the viewpoint of odor and permeation promoting effect. See noticeably improved permeability.

くすこともできる。The surfactant enhances the function of the release agent in developing and penetrating the coating film and the function of accelerating the water-solubility of the main agent. Even if only a nonionic surfactant is added, the function can be sufficiently ensured. Depending on the content of the formulation, it is desirable to use an anionic or cationic surfactant in combination. The mixing ratio of these components is not particularly limited, but it is preferable that the glycol ether as the main component is 80 to 95% by weight, the organic solvent is 5 to 20% by weight, and the surfactant is 0 to 1% by weight. Water can be added as needed to eliminate the flash point.

Although the release agent of the present invention is effective for general use of coating film peeling, it exerts an excellent effect particularly when applied to the coating film peeling of a building outer wall. An appropriate amount of the release agent of the present invention, which has been thickened by an inorganic additive, is applied to the painted surface of the outer wall of the building from an empirical value using an airless brush or a brush or a roller. The active ingredient of the release agent, while adhered to the coating film, quickly penetrates into the coating film and swells, and peels off the boundary surface between the outer wall base surface (background) and the coating film.

Can be reduced to zero. For example, about in the non-treated group per 1m 2 10
What took 15 minutes will be speeded up to 2-4 minutes. The release agent residue that does not penetrate into the coating film or remains on the outer wall foundation (background) easily dissolves in water, not only has no effect on repainting, but also makes the effluent cleaning liquid harmless. Incidentally, the high-pressure water washing machine used in the present invention desirably has a discharge rate of 25 l / min or more and a water pressure of 300 kg / cm 2 or more, and water may be at normal temperature. Preferably, it is water. Hereinafter, examples of the present invention will be described.

The transferability from the roller is good and the work is easy. It could be applied with a uniform thickness irrespective of the surface irregularities. When observed on the next day, the release agent is uniformly attached to the outer wall as in the case of application the previous day, and no sagging or the like is observed at all. Almost no dissolution of the coating film was observed.

When a solvent is used, the dissolving power is strong, so that the peeled coating film becomes a paint and adheres again to stain the surroundings. However, since the peeling is due to softening plasticization, there is no flow from the wall surface and the surroundings are not stained. Most of the active ingredient penetrated into the coating film, and a small amount of the release agent flowed out by the water of the washing machine, and the processing liquid that flowed out was dispersed or dissolved in water.

Unlike those using methylene chloride, it is gentle on the skin and has little odor. Since the workability is good and there is no volatilization from the side where the coating is applied, the coating amount can be easily adjusted, and the coating amount can be less than half.

Organic solvents as penetration enhancers
Immediately penetrates and swells the coating without dissolving it. As a result, the coating film is plasticized and softened, and can be peeled off without affecting the outer wall foundation (background). In addition, the residue of the release agent remaining on the coating film surface that is not used is dispersed or dissolved in water, and non-toxic inorganic substances settle with time, and organic substances such as glycol ether are easily biodegraded. Also less.

However, the peeling agent and the peeling method of the present invention are not limited to the coating film on the outer wall of the building. It can be used sufficiently if the paint or the like can be applied to the wall surface of the above, the peeling of the coating film on the rooftop or the guide floor, and the like.
