Problems solved by technology

[0003] However, when the device is disassembled and cleaned, it takes time to disassemble the device, so there is a problem that it takes time for cleaning
In addition, when replacing with the base resin to be used next, there is a problem that a large amount of base resin has to be used for sufficient replacement, and it takes time.

Embodiment 1

[0061] 93.6 parts of polyethylene (MFR=0.14g / 10min), 4.5 parts of zinc stearate (mp=125°C), 1.5 parts of ethylene biscapric acid amide (mp=161°C), and 0.2 parts of phenolic antioxidant , and 0.2 parts of phosphoric acid-based antioxidants were put into a mixer and stirred to obtain a mixture. The obtained mixture was charged into a twin-screw extruder (screw diameter: 30 mmφ), melt-kneaded and extruded at 200° C. to obtain strands. The obtained strands were cut with a pelletizer to obtain a pale yellow-brown pellet-like cleaning resin composition.

Embodiment 2～10、 comparative example 1～3

[0063] Except having used each component so that it may be the composition (unit: part) shown in Table 1, it carried out similarly to the said Example 1, and obtained the resin composition for cleaning of pellet form. It should be noted that, for Comparative Example 1, components other than fatty acid amide (ethylene biscapric acid amide) were used to prepare a resin composition for cleaning, and the amount of fatty acid amide (ethylene biscapric acid amide) shown in Table 1 was added during cleaning. capric acid amide).

Abstract

Provided is a resin composition for cleaning which is excellent in cleaning properties, easy to replace with subsequent resins, and easy to handle. A cleaning resin composition used for cleaning the inside of an extruder or molding machine for resin materials. The resin composition for cleaning contains a base resin and an additive, and the additive contains metal soap and at least any one of fatty acid amide and mineral oil (wherein, when the fatty acid amide is included, the total mass of the resin composition for cleaning is taken as Standard, the content of fatty acid amide is 1.0% by mass or more), and the base resin is a thermoplastic resin with a melt flow rate of 1.0 g / 10 minutes or less (wherein the content of the inorganic filler is 3 parts by mass or more).

Description

technical field [0001] The present invention relates to a cleaning resin composition for cleaning the inside of an extruder or a molding machine of a resin material. Background technique [0002] Various components such as resins and colorants that have been kneaded or molded in the past may remain inside the extruder or molding machine. If a thermoplastic resin is kneaded using an extruder or the like in which various components remain inside, the various components remaining in the obtained kneaded product, molded product, etc. are likely to be mixed in the form of impurities, which may cause physical problems. Possibility of abnormalities, poor appearance, etc. Therefore, when changing the product to be manufactured, in order to remove the internal residue, it is necessary to take the following measures: disassemble and clean the extruder and other equipment; replace it with the base resin to be used next; clean it with a cleaning agent; Wait. [0003] However, when th...
