らない等の煩雑な作用を伴う欠点がある。In plastic molding and processing, several measures are taken to eliminate the influence of the preceding product when changing products. In particular, when processing colored products, changing the color from dark grades such as blue or black to light grades such as white requires complicated work such as cleaning the inside of the molding machine with cleaning resin and disassembling and cleaning the molding machine. The reality is that we are forced to suspend production due to this. For example, in the case of color change in extrusion granulation molding, it is necessary to stop the extruder, remove the screw, clean the inside of the screw and cylinder by brushing, etc., and then reinstall the screw. Using resin to replace the previous product without removing the screw requires a large amount of resin for cleaning, and the complicated structure inside the extruder cannot be cleaned, resulting in coloring of the subsequent resin. There is a problem. Cleaning compounds are used to overcome these problems. The idea is to use a cleaning compound to make it easier to remove residue inside the extruder, and to use a small amount of replacement resin to change product types. There are cleaning compounds that contain lubricants such as stearic acid and those that use acrylic resin with a high melting temperature, but the former are not sufficiently effective, and the latter have a strong odor. In addition, due to the high melt viscosity, there is a drawback that the cleaning compound must be used after removing the die, breaker plate, wire gauze, etc., resulting in complicated operations.

。By using the cleaning thermoplastic resin composition provided by the present invention, a highly effective method for cleaning molding machines during grade change in plastic processing has been realized. That is, by using a small amount of the composition of the present invention, the amount consumed can be significantly reduced compared to when cleaning the molding machine is performed only by replacing the molding machine with a resin supplied later. Taking an injection molding machine as an example, if the composition of the present invention is used in combination with the color change using only the subsequent resin,
The amount of replacement resin required could be reduced to 1/8 or less, and the time required for color change could also be reduced to 1/6 or less.
