ている。2. Description of the Related Art In recent years, the recycling of resin products has been called for due to the growing concern about environmental problems and the reuse of resources. For example, in the process that occurs when manufacturing resin products such as bumpers and side moldings in the field of automobile industry. Attention has been paid to the recycling of resin products that are separated and collected from defective products and scrapped vehicles.

する。In many cases, resin products such as bumpers and side moldings are coated on the surface of the products in order to improve appearance and quality. For example, the skin of a bumper has a coating film formed on a resin material of a thermoplastic resin such as polypropylene resin via a primer layer made of a thermoplastic resin such as chlorinated polyolefin resin. This coating film is a thermosetting resin such as aminopolyester type, aminoacrylic type, polyesterurethane type, acrylicurethane type resin, etc. Although these resins are liquid before the curing reaction, a crosslinked structure is imparted by the baking coating process. To be done. Because of its strong and dense structure, the painted resin bumper has excellent chemical resistance, heat resistance, abrasion resistance, weather resistance and surface gloss.

の不具合がある。However, if the coated bumper is crushed as it is, pelletized and reused, the coating film pieces are mixed in the polypropylene resin material constituting the material of the resin product, and the coating film pieces are mixed. In the molding process using polypropylene resin material, the coating film piece obstructs the fluidity of the molten resin and causes molding defects such as "burn", "weld mark", "air bubbles" in the resin product, and There is a problem that coating film pieces protruding on the surface of the resin product impair the appearance of the resin product.

制限される。Further, since the coating film piece is a thermosetting resin and the polypropylene resin as the base resin is a thermoplastic resin, there is almost no interaction between the coating film piece and the base resin, and there is a slight dispersion. The uncoated coating pieces prevent the kneading and integration in the recycled resin to significantly reduce the mechanical properties of the recycled resin product, and the range of applications of the recycled resin product is greatly limited.

に機械的、物理的及び化学的方法がある。Therefore, when recycling a resin product that has been subjected to coating treatment, it is necessary to remove the coating film. As a method for peeling and removing the coating film from the coated resin product, a method published by the Japan Society of Automotive Engineers Automotive Technology Vol. 46.
NO. There are mechanical, physical and chemical methods as disclosed on pages 3-9 of 5,1992.

ュ法がある。The mechanical coating film removing method is, for example, a shot in which fine particles of a cleaning agent are sprayed onto the surface of a coating film formed on a resin product by using compressed air to destroy and remove the coating film and deposits. There are a blast method and a screen mesh method in which a resin product is finely pulverized, then melted in an extruder and filtered through a screen mesh to remove mixed coating pieces without melting.

リーンメッシュ交換を要する等の不具合がある。[0008] The shot blasting method is excellent in toxicity and environmental safety since it removes the coating film by friction or impact, but on the other hand, it requires a great number of treatment steps and is not sufficiently efficient in removing the coating film. It is difficult to process uneven parts. On the other hand, the screen mesh method is excellent in toxicity and environmental safety because it removes the coating film piece by filtration, but it causes clogging of the screen mesh by the unmelted coating film piece, and the extrusion pressure remarkably increases and the extrusion amount decreases. The production amount is reduced, the efficiency of removing the coating film pieces is not sufficient, and there is a problem that the screen mesh needs to be replaced in order to avoid the reduction of the production efficiency due to the clogging of the screen mesh.

それがある。The physical coating film removing method uses a halogen-based solvent or various organic solvents and removes the coating film by utilizing the solvent penetration into the boundary surface between the coating film and the material and the swelling phenomenon of the coating film by the solvent. However, it is inferior in environmental safety, has a relatively low coating film removal efficiency and processing capacity, and may deteriorate the material.

分解除去する有機塩法がある。The chemical coating film removing method is, for example, an organic salt method in which an organic salt-containing mixed solution of ethanol and water is used to chemically decompose and remove the coating film by breaking the ether bond in the vicinity of the crosslinking point of the release resin. is there.
【００１１】この塗膜除去方法は、排水処理等の２次処

4 is set to be lower than the rotation peripheral speed of 4 to apply cutting force and high frictional force to the coating film 102a and the double-sided tape 102b of the side molding 102, and the side molding 1
The coating film 102a and the double-sided tape 102b on the surface of No. 02 are cut and separated, and the side molding 102 is carried out to the outside by the pair of conveying rollers 101.
