しかし、前者は洗浄効果が不十分であり、後者はシリン
ダーやスクリュー表面等に傷を付け易い欠点がある。However, the former has a drawback that the cleaning effect is insufficient, and the latter has a defect that the surface of the cylinder or the screw is easily scratched.
又、溶融粘度の高いアクリル系樹脂を使用する方法もあ
るが、これは洗浄の際、成形機に大きな負荷がかかるば
かりでなく、悪臭が発生し易い等の欠点がある。There is also a method of using an acrylic resin having a high melt viscosity, but this has a drawback that not only a large load is applied to the molding machine at the time of cleaning, but also a bad odor is easily generated.
上述したことから明らかのように、本発明の目的は、少

動、変形を助けている。しかも、圧力が除かれた後に
は、弾性が回復するものである。As its characteristic physical property, when it is uniformly dispersed in rubber in the form of small particles, it shows plasticity when a strong force such as kneading is applied, it works as a lubricant, and it helps the flow and deformation of the rubber compound. Moreover, elasticity is restored after the pressure is removed.
そして、その構造は非熱可塑性物質であり、大別する
と、次の３種類（ポリマーダイジェスト 1986年８月号
70〜71ページ ラバーダイジェスト社発行）に分けられ
る。Its structure is a non-thermoplastic material, and it can be roughly classified into the following three types (polymer digest, August 1986 issue).
Page 70-71 issued by Rubber Digest).
（Ｉ） 硫黄ファクチス（黒サブ、黄サブ） 酸化させた植物油、魚油、鉱物油等を硫黄で加熱加硫架
橋した弾性体。(I) Sulfur factice (black sub, yellow sub) An elastic body obtained by vulcanizing and cross-linking oxidized vegetable oil, fish oil, mineral oil and the like with sulfur.

It is intended to cross-link oligomers and the like, and at this time, sulfur and sulfur chloride are not used, and as a cross-linking agent, peroxide,
It is an elastic body obtained by using isocyanate and azobisisobutyronitrile.
本発明の（Ｃ）成分の滑剤は、内部滑剤と外部滑剤の中
から選択できる。例えば、高級脂肪酸アミド、高級アル
コール、グリセリンエステル、ソルビタンエステル、高
級脂肪酸、ポリエチレンワックス、ビスアミド、高級脂
肪酸金属塩等が挙げられる。The lubricant as the component (C) of the present invention can be selected from internal lubricants and external lubricants. For example, higher fatty acid amide, higher alcohol, glycerin ester, sorbitan ester, higher fatty acid, polyethylene wax, bisamide, higher fatty acid metal salt and the like can be mentioned.
（Ｄ）成分の非イオン系界面活性剤としては、ポリオキ
シエチレンアルキルエーテル、ソルビタン脂肪酸エステ
ル、ポリオキシエチレンソルビタン酸エステル、グリセ
リン脂肪酸エステル等、通常、非イオン系界面活性剤と
して使用されているものであれば良い。As the nonionic surfactant as the component (D), polyoxyethylene alkyl ether, sorbitan fatty acid ester, polyoxyethylene sorbitan acid ester, glycerin fatty acid ester and the like, which are usually used as nonionic surfactants If it is good.
本発明に於いて、（Ｂ）成分の配合量は、（Ａ）成分10
0部に対して１〜30部使用する。１部より少ないと洗浄
剤として使用する際に、効果的な粘弾性が得られずこの
ため十分な洗浄効果が発揮できない。又、30部より多い
と洗浄の際に、流れが悪くなり滞留し熱劣化を生じ好ま
しくない。In the present invention, the blending amount of the component (B) is 10 parts of the component (A).
Use 1 to 30 parts for 0 parts. If the amount is less than 1 part, effective viscoelasticity cannot be obtained when used as a cleaning agent, and therefore a sufficient cleaning effect cannot be exhibited. On the other hand, if the amount is more than 30 parts, it is not preferable because the flow is deteriorated during the washing, and it stays and causes thermal deterioration.
（Ｃ）成分の配合量は、0.05〜８部である。0.05部以下
では、洗浄剤がシリンダーやスクリューの表面に付着し
易くなり好ましくない。又、８部以上では洗浄剤がシリ
ンダー内でスリップし、成形機内に残存する先行品種の
押し出しが困難となり作業性が低下して好ましくない。The compounding amount of the component (C) is 0.05 to 8 parts. If the amount is less than 0.05 parts, the detergent tends to adhere to the surfaces of the cylinder and the screw, which is not preferable. On the other hand, if the content is 8 parts or more, the detergent slips in the cylinder, which makes it difficult to extrude the preceding product remaining in the molding machine, which lowers the workability, which is not preferable.
（Ｄ）成分の配合量は、0.5〜15部である。0.5部以下で
は、シリンダー内に付着している洗顔料の色落ちが悪
く、又、15部以上配合しても、その効果は変らず、従っ
て15部以下でよい。The compounding amount of the component (D) is 0.5 to 15 parts. If it is 0.5 parts or less, the color wash of the face wash adhering to the inside of the cylinder is poor, and if 15 parts or more is blended, the effect does not change. Therefore, 15 parts or less is sufficient.
本発明の成形機用洗浄剤には、上記の４成分のほかに必
要に応じて、安定剤（特に酸化防止剤）、無機物（タン
カル、ケイソウ土、カオリン等）を配合してもよい。特
に、酸化防止剤は、フェノール系、アミン系、有機硫黄

05〜５部が好ましく、これにより洗浄剤を成形機内に滞
留させることが可能となり、洗浄中にシリンダー内に本
発明の成形機用洗浄剤を滞留させることで、本発明の洗
浄効果が更に向上する。The detergent for a molding machine of the present invention may contain a stabilizer (particularly an antioxidant) and an inorganic substance (tankal, diatomaceous earth, kaolin, etc.) in addition to the above-mentioned four components. In particular, the antioxidant may be any of phenol-based, amine-based, organic sulfur-based, phosphite-based, etc.
05 to 5 parts is preferable, which makes it possible to retain the cleaning agent in the molding machine. By retaining the cleaning agent for a molding machine of the present invention in the cylinder during cleaning, the cleaning effect of the present invention is further improved. To do.
本発明の成形機用洗浄剤の製造は、通常の方法で得られ

比較例１ 実施例１での（Ｂ）成分の使用量を0.5部とする以外
は、実施例１と同じ配合で洗浄剤を得る。Comparative Example 1 A detergent is obtained in the same composition as in Example 1 except that the amount of the component (B) used in Example 1 is 0.5 part.
この後、該洗浄剤2kgを使用し、実施例１と同じ条件で
洗浄を試みた後に、ナチュラルレジン5kgにより洗浄剤
の排除を行った。After that, 2 kg of the detergent was used, washing was attempted under the same conditions as in Example 1, and then the detergent was removed by 5 kg of natural resin.
しかし、フタロシアニンブルーが残り満足すべき結果が
得られなかった。However, phthalocyanine blue remained and the satisfactory result was not obtained.
比較例２ 実施例１での（Ｄ）成分の使用量を0.2部とする以外

A 2 ounce injection molding machine molded using the S resin composition was washed with 2 kg of natural resin for 30 minutes, but blue streaks remained, and a satisfactory result was not obtained.
本発明の成形機用洗浄剤は、（Ｂ）成分のファクチスを
配合してあることに大きな特徴を有するものである。The cleaning agent for a molding machine of the present invention is characterized in that it contains the factice as the component (B).
成形機内で加熱された本発明の洗浄剤は、まず、（Ｄ）
非イオン系界面活性剤が溶け出し、これがシリンダー壁

性を有する（Ｂ）ファクチスが、かき落し、吸着するの
である。The cleaning agent of the present invention heated in the molding machine is (D)
The nonionic surfactant dissolves out, and this penetrates into the resin, colorant, etc. adhering to the cylinder wall surface and screw surface, swells, and facilitates peeling. The (B) factice having an appropriate rubber elasticity scrapes and adsorbs this.
又、加熱により（Ａ）熱可塑性樹脂が溶融した時や、
（Ｃ）滑剤や（Ｄ）非イオン系界面活性剤を多量に配合

機内の残存樹脂組成物を効率よく排除できるのである。Also, when the thermoplastic resin (A) is melted by heating,
Even when a large amount of (C) a lubricant or (D) a nonionic surfactant is blended, the presence of (B) factice imparts an appropriate rubber elasticity to the detergent for a molding machine of the present invention. The resin composition that does not adhere to the surface of the screw and that remains in the molding machine can be efficiently removed.
このように本発明の成形機用洗浄剤を使用することによ
