Description of the Related Art Conventionally, various plastic moldings made of polyolefins such as polypropylene, polyurethane resins, polycarbonate resins, polyester resins and the like have been widely used in automobile parts and the like. The surface of these plastic molded products is usually coated with a paint for the purpose of imparting an aesthetic appearance and various properties such as weather resistance and chemical resistance.

剥離作業が大変であった。Most of the plastic moldings having a coating film on their surfaces are discarded when they are no longer needed. For example, when disposing of an automobile, plastic automobile parts such as bumpers are not reused like metal materials,
It was generally disposed of. However, in recent years, the total amount of these plastic moldings to be disposed of has become enormous, and therefore, from the viewpoint of resource saving, plastic moldings can be collected, like metal materials,
The motivation to reuse or recycle is spreading. However, if a plastic molded product having a coating film on its surface is reused as it is, the coating film remains as an impurity, which causes various problems.
Therefore, it is necessary to peel off the coating film and reuse the plastic molded product, but since the coating film is originally firmly attached to the plastic molded product from its use,
The peeling work was difficult.

On the other hand, a strongly acidic or strongly alkaline solution is highly toxic and both of them have a problem of environmental pollution. is doing. In view of such a current situation, the present inventors have earnestly sought to develop a release agent that is less likely to cause environmental pollution and is inexpensive, and that can remove a coating film on the surface of a plastic molded product in a short time. As a result of examination, the present invention has been achieved.

Put a release agent at room temperature or in a heated container in a treatment container, preferably a closed container, and immerse the plastic molded product with the coating film on the surface to swell the coating film within a few minutes to a few hours. The coating film peels off. The plastic molded product may be immersed in the original shape,
It is needless to say that a piece cut and cut into pieces may be immersed in relation to the peeling efficiency, the size of the processing container, and the like.

もない。After peeling the coating film from the surface of the plastic molded product in this manner, the release agent is separated from the coating film and the plastic molded product by a method such as a filtration separation method or a distillation separation method and reused. That is, it is desirable to carry out each of the above processes by a closed system. Although the release agent of the present invention has been described as being applied only to a plastic molded product, it goes without saying that the release agent can also be applied to release a coating film from an article to be coated such as a metal product or a ceramic product.
