Description
本発明は、潤滑剤を間欠的に供給することにより、潤滑剤の使用量を大幅に削減することのできるボトルコンベア用潤滑剤組成物に関する。 The present invention relates to a lubricant composition for bottle conveyors that can significantly reduce the amount of lubricant used by intermittently supplying the lubricant.
清涼飲料水、牛乳、ジュース、酒類、ドリンク剤等の容器には、ポリエチレンテレフタレート等のプラスチック容器、紙製容器、金属製容器、ガラス製及びセラミック製容器等が使用されるが、工場においてこれらの容器を取り扱う場合、大量の容器を移動搬送するために一般的にボトルコンベアが使用されている。このような工場においては、ボトルコンベアを連続運転させることが一般的であるが、このとき容器とボトルコンベアとの接触面に発生する摩擦により容器の転倒等がおこる場合があり、こうした障害を防ぐために界面活性剤水溶液を潤滑剤として、容器やボトルコンベア上に噴霧して摩擦係数を下げるのが一般的である（例えば、特許文献１を参照）。 Plastic containers such as polyethylene terephthalate, paper containers, metal containers, glass and ceramic containers, etc. are used for containers such as soft drinks, milk, juice, alcoholic beverages, and drinks. When handling containers, a bottle conveyor is generally used to move and convey a large number of containers. In such a factory, it is common to operate the bottle conveyor continuously. At this time, the container may fall over due to friction generated on the contact surface between the container and the bottle conveyor. In order to reduce the friction coefficient, an aqueous surfactant solution is generally used as a lubricant on a container or a bottle conveyor (see, for example, Patent Document 1).
ボトルコンベア用潤滑剤は大量の水で希釈した希薄な溶液を、常に噴霧した状態で使用することが一般的であり、一般的な潤滑剤は噴霧を止めると潤滑剤としての機能が発揮されない。そのため、大量の潤滑剤を保管するタンク、使用後の潤滑剤の回収や廃棄等が必要となり、使用者にとって大きな負担となっている。 A lubricant for a bottle conveyor is generally used in a state where a diluted solution diluted with a large amount of water is always sprayed, and a general lubricant does not function as a lubricant when spraying is stopped. Therefore, a tank for storing a large amount of lubricant, recovery and disposal of the lubricant after use, and the like are necessary, which is a heavy burden on the user.
使用者の負担を軽減するためには、潤滑剤及び希釈水の使用量を削減することが必要である。そこで水で希釈しないタイプあるいは水での希釈率が低い潤滑剤が知られている（例えば、特許文献２を参照）。こうした潤滑剤は、高濃度の潤滑剤をボトルコンベア上に噴霧し、なるべく潤滑剤の使用量を少なくすることが目的であるが、基本的には連続的に潤滑剤を噴霧しなければならず、使用量の削減はそれほど望むことができなかった。また、潤滑剤の使用量を削減するために間欠的な噴霧を行う方法があるが、高濃度の潤滑剤であっても噴霧していない時間が長時間続くと、ボトルコンベア上の潤滑性が低下するため、潤滑剤を噴霧しなくてもよい時間はわずかであり、潤滑剤の使用量を削減できるほどの間欠噴霧を行うことはできなかった。 In order to reduce the burden on the user, it is necessary to reduce the amount of lubricant and dilution water used. Therefore, a type that is not diluted with water or a lubricant with a low dilution rate with water is known (see, for example, Patent Document 2). The purpose of these lubricants is to spray a high-concentration lubricant onto the bottle conveyor to reduce the amount of lubricant used as much as possible, but basically the lubricant must be sprayed continuously. The reduction in usage was not so much desired. In addition, there is a method of intermittent spraying to reduce the amount of lubricant used, but even if it is a high concentration lubricant, if it is not sprayed for a long time, the lubricity on the bottle conveyor will be Therefore, the time that the lubricant does not have to be sprayed is very short, and intermittent spraying that can reduce the amount of lubricant used cannot be performed.
従って、本発明が解決しようとする課題は、潤滑剤の使用量を削減することのできるボトルコンベア用潤滑剤組成物及びその使用方法を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a lubricant composition for bottle conveyors that can reduce the amount of lubricant used and a method for using the same.
そこで本発明者等は鋭意検討し、間欠噴霧をするのに最適なボトルコンベア用潤滑剤組成物を見出し、本発明に至った。即ち、本発明は、（Ａ）成分として、ソルビトール、マンニトール、ＤＬ−ピロリドンカルボン酸又はその塩、グリコール酸又はその塩、乳酸又はその塩、及び下記の一般式（１）

（式中、ｍは３〜１０００の数を表す。）で表わされるポリエチレングリコールから選択される１種または２種以上の化合物１００質量部に対して、（Ｂ）成分として、下記の一般式（２）

（式中、Ｒは炭素数８〜１８の脂肪族炭化水素基を表し、ｎは３〜５０の数を表わし、Ａは炭素数２〜４のアルキレン基を表す。但し、ｎ個あるＡの５０モル％以上はエチレン基でなければならない。）で表わされるノニオン界面活性剤を１〜２００質量部含有し、且つアニオン界面活性剤を５質量部以上含有しないことを特徴とするボトルコンベア用潤滑剤組成物である。
Therefore, the present inventors diligently studied and found a lubricant composition for bottle conveyors that is optimal for intermittent spraying, leading to the present invention. That is, the present invention provides the component (A) as sorbitol, mannitol, DL-pyrrolidonecarboxylic acid or a salt thereof, glycolic acid or a salt thereof, lactic acid or a salt thereof, and the following general formula (1)
H- (OC 2 H 4) m -OH (1)
(Wherein m represents a number of 3 to 1000), 100 parts by mass of one or more compounds selected from polyethylene glycol represented by the following general formula (B) 2)
R- (OA) n -OH (2)
(In the formula, R represents an aliphatic hydrocarbon group having 8 to 18 carbon atoms, n represents a number of 3 to 50, and A represents an alkylene group of 2 to 4 carbon atoms, provided that n number of A 50 mol% or more must be an ethylene group.) 1 to 200 parts by mass of a nonionic surfactant represented by the formula (1), and 5 parts by mass or more of an anionic surfactant. Agent composition.
本発明の効果は、間欠噴霧により、潤滑剤の使用量を削減することのできるボトルコンベア用潤滑剤組成物及びその使用方法を提供したことにある。 The effect of this invention exists in providing the lubricant composition for bottle conveyors which can reduce the usage-amount of a lubricant, and its usage method by intermittent spraying.
本発明の（Ａ）成分は、ソルビトール、マンニトール、ＤＬ−ピロリドンカルボン酸またはその塩、グリコール酸またはその塩、乳酸またはその塩、及び下記の一般式（１）で表わされるポリエチレングリコールから選択される。
Ｈ−（ＯＣ２Ｈ４）ｍ−ＯＨ （１）
（式中、ｍは３〜１０００の数を表す。）
The component (A) of the present invention is selected from sorbitol, mannitol, DL-pyrrolidonecarboxylic acid or a salt thereof, glycolic acid or a salt thereof, lactic acid or a salt thereof, and polyethylene glycol represented by the following general formula (1). .
H- (OC 2 H 4) m -OH (1)
(In the formula, m represents a number of 3 to 1000.)
ＤＬ−ピロリドンカルボン酸塩、グリコール酸塩、乳酸塩に使用される塩としては、ナトリウム塩、カリウム塩等のアルカリ金属塩；マグネシウム塩、カルシウム塩等のアルカリ土類金属塩が挙げられる。これらの塩の中でも、間欠噴霧に適していることから、アルカリ金属塩が好ましく、ナトリウム塩がより好ましい。なお、間欠噴霧に対するこれら成分の効果についての詳しい説明は後述する。 Examples of salts used for DL-pyrrolidone carboxylate, glycolate and lactate include alkali metal salts such as sodium salt and potassium salt; alkaline earth metal salts such as magnesium salt and calcium salt. Among these salts, alkali metal salts are preferable and sodium salts are more preferable because they are suitable for intermittent spraying. In addition, the detailed description about the effect of these components with respect to intermittent spraying is mentioned later.
（Ａ）成分であるポリエチレングリコールの分子量は、ｍの値が３〜１０００の数であればいずれの分子量であってもかまわないが、潤滑性や噴霧性が良好なことから、ｍの値は３〜５００が好ましく、３〜１００がより好ましく、３〜５０が更に好ましく、３〜１０が最も好ましい。ｍの値が３より小さい場合は良好な潤滑性が得られず、ｍの値が１０００より大きい場合は水に溶解したときの粘度が上昇するため取り扱いが困難になる場合や、使用時の噴霧等がうまくできない場合がある。（Ａ）成分は、上記に挙げた化合物の１種を使用しても、２種以上の混合物を使用してもよい。 The molecular weight of polyethylene glycol as component (A) may be any molecular weight as long as the value of m is a number from 3 to 1000, but since the lubricity and sprayability are good, the value of m is 3-500 are preferable, 3-100 are more preferable, 3-50 are still more preferable, and 3-10 are the most preferable. When the value of m is less than 3, good lubricity cannot be obtained, and when the value of m is more than 1000, the viscosity when dissolved in water increases, making it difficult to handle or spraying during use. Etc. may not work well. (A) A component may use 1 type of the compound quoted above, or may use 2 or more types of mixtures.
本発明の（Ｂ）成分は、下記の一般式（２）で表わされる。
Ｒ−（ＯＡ）ｎ−ＯＨ （２）
（式中、Ｒは炭素数８〜１８の脂肪族炭化水素基を表し、ｎは３〜５０の数を表わし、Ａは炭素数２〜４のアルキレン基を表す。但し、ｎ個あるＡの５０モル％以上はエチレン基でなければならない。）
The component (B) of the present invention is represented by the following general formula (2).
R- (OA) n -OH (2)
(In the formula, R represents an aliphatic hydrocarbon group having 8 to 18 carbon atoms, n represents a number of 3 to 50, and A represents an alkylene group of 2 to 4 carbon atoms, provided that n number of A 50 mol% or more must be ethylene group.)
一般式（２）のＲは炭素数８〜１８の脂肪族炭化水素基を表すが、こうした炭化水素基としては、例えば、直鎖及び分岐のオクチル基、２−エチルヘキシル基、２級オクチル基、直鎖及び分岐のノニル基、２級ノニル基、直鎖及び分岐のデシル基、２級デシル基、直鎖及び分岐のウンデシル基、２級ウンデシル基、直鎖及び分岐のドデシル基、２級ドデシル基、直鎖及び分岐のトリデシル基、２級トリデシル基、直鎖及び分岐のテトラデシル基、２級テトラデシル基、直鎖及び分岐のヘキサデシル基、２級ヘキサデシル基、直鎖及び分岐のステアリル基、２−ブチルオクチル基、２−ブチルデシル基、２−ヘキシルオクチル基、２−ヘキシルデシル基、２−オクチルデシル基、２−ヘキシルドデシル基、モノメチル分枝−イソステアリル基等のアルキル基；オクテニル基、ノネニル基、デセニル基、ウンデセニル基、ドデセニル基、テトラデセニル基、オレイル基等のアルケニル基が挙げられる。これらの中でも、潤滑剤をボトルコンベア上に均一に保持させる効果に優れていることから、炭素数１０〜１６の脂肪族炭化水素基が好ましく、炭素数１０〜１６のアルキル基がより好ましい。なお、潤滑剤をボトルコンベア上に均一に保持させる効果については、以下に詳しく記載する。 R in the general formula (2) represents an aliphatic hydrocarbon group having 8 to 18 carbon atoms. Examples of such hydrocarbon groups include linear and branched octyl groups, 2-ethylhexyl groups, secondary octyl groups, Linear and branched nonyl groups, secondary nonyl groups, linear and branched decyl groups, secondary decyl groups, linear and branched undecyl groups, secondary undecyl groups, linear and branched dodecyl groups, secondary dodecyl groups Group, linear and branched tridecyl group, secondary tridecyl group, linear and branched tetradecyl group, secondary tetradecyl group, linear and branched hexadecyl group, secondary hexadecyl group, linear and branched stearyl group, 2 -Butyl octyl group, 2-butyl decyl group, 2-hexyl octyl group, 2-hexyl decyl group, 2-octyl decyl group, 2-hexyl decyl group, monomethyl branched-isostearyl group, etc. Alkyl group; octenyl group, nonenyl group, decenyl group, undecenyl group, dodecenyl group, tetradecenyl group, and an alkenyl group such as oleyl group. Among these, an aliphatic hydrocarbon group having 10 to 16 carbon atoms is preferable and an alkyl group having 10 to 16 carbon atoms is more preferable because it is excellent in the effect of uniformly holding the lubricant on the bottle conveyor. The effect of holding the lubricant uniformly on the bottle conveyor will be described in detail below.
一般式（２）のＡは炭素数２〜４のアルキレン基であり、例えば、エチレン基、プロピレン基、イソプロピレン基、ブチレン基、イソブチレン基等が挙げられる。
一般式（２）で表される化合物は、上記の１価有機ヒドロキシ化合物にアルキレンオキシドを付加することによって得られるが、その重合形態は特に限定されず、エチレンオキシドの単独重合、エチレンオキシドとプロピレンオキシドとのランダム共重合、ブロック共重合、ランダム／ブロック共重合等でよい。一般式（２）で表される化合物のポリオキシアルキレン基に占めるオキシエチレン基の割合は、５０〜１００モル％となるようにエチレンオキシドの配合比を調整すればよく、６０〜９５モル％が好ましく、６５〜９０モル％がより好ましい。オキシエチレン基の割合が５０モル％未満になると潤滑性が不足する場合や製品安定性が不安定になる場合がある。なお、オキシエチレン基の割合が９５モル％を超えると使用時の泡立ちが大きくなるため長時間の連続使用が困難になる場合、容器に印刷された印字が脱落する場合、濡れ性が低下して潤滑剤が均等に塗布できない場合、あるいは水混入時に潤滑性性能が低下する等の問題を生じる場合がある。
A in the general formula (2) is an alkylene group having 2 to 4 carbon atoms, and examples thereof include an ethylene group, a propylene group, an isopropylene group, a butylene group, and an isobutylene group.
The compound represented by the general formula (2) is obtained by adding alkylene oxide to the above monovalent organic hydroxy compound, but the polymerization form is not particularly limited, and ethylene oxide homopolymerization, ethylene oxide and propylene oxide, Random copolymerization, block copolymerization, random / block copolymerization, and the like. What is necessary is just to adjust the compounding ratio of ethylene oxide so that the ratio of the oxyethylene group to the polyoxyalkylene group of the compound represented by the general formula (2) may be 50 to 100 mol%, preferably 60 to 95 mol%. 65 to 90 mol% is more preferable. When the proportion of oxyethylene groups is less than 50 mol%, lubricity may be insufficient or product stability may be unstable. If the ratio of oxyethylene groups exceeds 95 mol%, foaming during use becomes large and continuous use for a long time becomes difficult. If the print printed on the container drops off, the wettability decreases. In some cases, the lubricant cannot be evenly applied, or there may be a problem that the lubricity performance deteriorates when mixed with water.
本発明のボトルコンベア用潤滑剤組成物の潤滑性能の持続性に悪影響を与えることから、アニオン界面活性剤の配合量は制限される。具体的には、（Ａ）成分１００質量部に対するアニオン界面活性剤の配合量（２種以上アニオン界面活性剤が含有している場合はその合計量。）は５質量部未満でなければならず、３質量部未満が好ましく、１質量部未満がより好ましく、実質配合しないことが最も好ましい。 Since it adversely affects the durability of the lubricating performance of the lubricant composition for bottle conveyors of the present invention, the amount of the anionic surfactant is limited.

本発明のボトルコンベア用潤滑剤組成物は、（Ａ）成分１００質量部に対して、（Ｂ）成分を１〜２００質量部、好ましくは２〜１００質量部、より好ましくは５〜５０質量部含有したものである。（Ｂ）成分の配合量が少なすぎるとコンベア上の濡れ性が悪くなる場合があり、（Ｂ）成分の配合量が多すぎるとボトルコンベア上で泡が発生する場合や、潤滑性が不足する場合がある。 In the lubricant composition for a bottle conveyor of the present invention, the component (B) is 1 to 200 parts by weight, preferably 2 to 100 parts by weight, more preferably 5 to 50 parts by weight, with respect to 100 parts by weight of the component (A). Contains. If the blending amount of the component (B) is too small, the wettability on the conveyor may be deteriorated. If the blending amount of the component (B) is too large, bubbles may be generated on the bottle conveyor, or the lubricity is insufficient. There is a case.
実際の配合量としては、水を溶媒として（Ａ）成分を０．２〜３０質量％、（Ｂ）成分を０．０５〜１０質量％配合することが好ましい。高濃度であるほうが輸送コストがかからないため、製品の輸送時等は（Ａ）成分を５〜３０質量％、好ましくは１０〜３０質量％、（Ｂ）成分を１〜１０質量％、好ましくは３〜１０質量％の水溶液に調整すればよい。またボトルコンベアに使用する場合は、（Ａ）成分を０．２〜５質量％、好ましくは０．２〜２質量％、（Ｂ）成分を０．０５〜２質量％、好ましくは０．０５〜１質量％の水溶液に調整すればよい。使用時の調整としては、高濃度の潤滑剤組成物を１〜５０倍に水で希釈することが好ましい。 As an actual blending amount, it is preferable to blend 0.2 to 30% by mass of component (A) and 0.05 to 10% by mass of component (B) using water as a solvent. The higher the concentration, the lower the transportation cost. Therefore, when transporting the product, the component (A) is 5 to 30% by mass, preferably 10 to 30% by mass, and the component (B) is 1 to 10% by mass, preferably 3 What is necessary is just to adjust to 10 mass% aqueous solution. Moreover, when using for a bottle conveyor, (A) component is 0.2-5 mass%, Preferably it is 0.2-2 mass%, (B) component is 0.05-2 mass%, Preferably it is 0.05. What is necessary is just to adjust to -1 mass% aqueous solution. As adjustment at the time of use, it is preferable to dilute a high concentration lubricant composition with water 1 to 50 times.
本発明のボトルコンベア用潤滑剤組成物の使用方法は、容器が流れているボトルコンベア上に均一に塗布あるいは噴霧すればよいが、潤滑剤の使用量を削減するために、間欠的に潤滑剤を噴霧することが好ましい。具体的な噴霧及び噴霧を停止する時間としては、例えば、１〜３００秒潤滑剤を噴霧した後、３００〜７２００秒噴霧を停止すればよく、好ましくは噴霧を停止している時間を６００〜７２００秒、より好ましくは１２００〜７２００秒、更に好ましくは２０００〜７２００秒にすればよく、噴霧を停止している時間が長いほど潤滑剤の使用量を減らすことができ、噴霧を停止している時間が短いと、潤滑剤の使用量を削減することが困難になる。また、潤滑剤の噴霧を停止している時間は、潤滑剤の噴霧時間に対して１０〜２００倍になるようにすることが好ましい。本発明のボトルコンベア用潤滑剤組成物は、潤滑剤の噴霧を停止できる時間を長くできることが最大の特徴である。 The method of using the lubricant composition for bottle conveyors of the present invention may be applied or sprayed uniformly on the bottle conveyor in which the containers are flowing, but in order to reduce the amount of lubricant used, the lubricant is intermittently used. Is preferably sprayed. As specific spraying and time for stopping the spraying, for example, after spraying the lubricant for 1 to 300 seconds, the spraying may be stopped for 300 to 7200 seconds, and preferably the time for stopping the spraying is 600 to 7200. Seconds, more preferably 1200 to 7200 seconds, and even more preferably 2000 to 7200 seconds. The longer the time during which spraying is stopped, the more the amount of lubricant used can be reduced, and the time during which spraying is stopped. If it is short, it becomes difficult to reduce the amount of lubricant used. Further, the time during which the spraying of the lubricant is stopped is preferably 10 to 200 times the spraying time of the lubricant. The greatest feature of the lubricant composition for bottle conveyors of the present invention is that the time during which spraying of the lubricant can be stopped can be lengthened.
搬送物としては、ボトルコンベアで使用するものであれば特に規定されないが、飲料物用の容器が好ましく、こうした容器の素材としては、例えば、ポリエチレンテレフタレート（ＰＥＴ）製、ポリエチレン製、ポリプロピレン製、ポリスチレン製、ポリアミド製、ポリカーボネート製等のプラスチック製容器；紙製容器（ワックス仕上げや樹脂コーティングを含む）；鉄製、アルミニウム製、錫製、銅製、亜鉛製、あるいはこれらの複合材料等の金属製容器；ガラス製容器；セラミックス製容器等が挙げられる。これらの容器の中でも、本発明の効果が顕著に表れることから、プラスチック製品が好ましく、ＰＥＴ製容器での使用がより好ましい。 The transported material is not particularly defined as long as it is used on a bottle conveyor, but a beverage container is preferable. Examples of the material of such a container include polyethylene terephthalate (PET), polyethylene, polypropylene, polystyrene. Made of plastic, polyamide, polycarbonate, etc .; paper containers (including wax finish and resin coating); metal containers such as iron, aluminum, tin, copper, zinc, or composite materials thereof; Glass containers; ceramic containers and the like. Among these containers, since the effect of the present invention is remarkably exhibited, plastic products are preferable, and use in PET containers is more preferable.
ここで、本発明に使用できる（Ａ）成分及び（Ｂ）成分の効果について更に詳しく説明する。今までのボトルコンベア用潤滑剤組成物は、通常、ボトルコンベア上に連続的に噴霧するものであった。連続的に噴霧する理由としては、噴霧を停止するとすぐに潤滑性がなくなってしまうためである。このため間欠噴霧の潤滑方式を実現させるためには、噴霧を長時間停止しても潤滑性を維持できなければならない。潤滑性が得られる化合物は多数あるが、例えば、プロピレングリコールやジプロピレングリコール等は潤滑性を長時間維持できず、グリセリン等は潤滑性を長時間維持できるが潤滑性が不良（摩擦係数が低すぎる）である。本発明の（Ａ）成分はこうした欠点がなく、好ましい潤滑性を長時間維持できる。 Here, the effects of the component (A) and the component (B) that can be used in the present invention will be described in more detail. Conventional lubricant compositions for bottle conveyors are usually sprayed continuously on bottle conveyors. The reason for spraying continuously is that the lubricity is lost as soon as spraying is stopped. Therefore, in order to realize an intermittent spray lubrication system, it is necessary to maintain lubricity even when spraying is stopped for a long time. There are many compounds that can achieve lubricity. For example, propylene glycol or dipropylene glycol cannot maintain lubricity for a long time, and glycerin or the like can maintain lubricity for a long time, but the lubricity is poor (the coefficient of friction is low). Too). The component (A) of the present invention does not have such disadvantages and can maintain a preferable lubricity for a long time.
しかし、（Ａ）成分と水との混合物をボトルコンベア上にまんべんなく噴霧した場合であっても、噴霧を停止するとボトルコンベア上の潤滑剤にかたよりが生じ、ボトルコンベア上に潤滑剤を均一に保持させることができない。それゆえ（Ａ）成分と水だけでは、ボトルコンベア上に潤滑剤が付着しない箇所（潤滑性がなくなる箇所）ができてしまう。当然のことながらそうした箇所は潤滑性がなく、その結果、ボトルコンベアの運転中に不具合が生じる。この問題を解決するために（Ｂ）成分を配合している。（Ｂ）成分は一般的に潤滑剤としての性能を示すことが知られているが、本発明における（Ｂ）成分は、（Ａ）成分の潤滑性を阻害せず、更に、ボトルコンベア上に（Ａ）成分を長時間均一に分散させるために配合してある。 However, even when the mixture of the component (A) and water is sprayed evenly on the bottle conveyor, when the spraying is stopped, the lubricant on the bottle conveyor is distorted, and the lubricant is evenly distributed on the bottle conveyor. It cannot be held. Therefore, with the component (A) and water alone, a location where the lubricant does not adhere to the bottle conveyor (location where the lubricity is lost) is formed. Of course, such locations are not lubricious, resulting in problems during operation of the bottle conveyor. In order to solve this problem, the component (B) is blended. Although it is known that the component (B) generally shows performance as a lubricant, the component (B) in the present invention does not hinder the lubricity of the component (A), and further on the bottle conveyor. (A) It mix | blends in order to disperse | distribute a component uniformly for a long time.
多くの界面活性剤は分散剤としての性能を持っているが、アニオン界面活性剤を（Ｂ）成分の代わりに使用しても、ボトルコンベア上に（Ａ）成分を均一に保持することができない。また、アニオン界面活性剤はボトルコンベア上で泡が発生する場合や、水に微量に含まれるカルシウム等との反応でカルシウム石鹸等の汚れを生じさせる場合があり、その結果潤滑性が悪化する場合もある。アニオン界面活性剤を本発明のボトルコンベア用潤滑剤組成物に添加すると、上記の悪影響が顕著に現れてしまうため、アニオン界面活性剤の添加量は制限しなくてはならない。また、（Ｂ）成分以外のノニオン界面活性剤やカチオン界面活性剤、両性界面活性剤を（Ｂ）成分の代わりに使用すると、潤滑性を悪化させる場合や、潤滑性を長時間維持することができない場合があるため、これらを(Ｂ)成分として使用することはできない。しかし、本発明のボトルコンベア用潤滑剤組成物に（Ｂ）成分以外のノニオン界面活性剤やカチオン界面活性剤、両性界面活性剤を添加しても、アニオン界面活性剤ほど悪影響を与えることはないため、本発明のボトルコンベア用潤滑剤組成物に（Ｂ）成分以外のノニオン界面活性剤やカチオン界面活性剤、両性界面活性剤は添加することは可能である。 Many surfactants have a performance as a dispersant, but even if an anionic surfactant is used instead of the component (B), the component (A) cannot be uniformly held on the bottle conveyor. . In addition, anionic surfactants may cause foaming on bottle conveyors, and may cause soiling of calcium soap, etc. due to reaction with a small amount of calcium in water, resulting in poor lubricity. There is also. When an anionic surfactant is added to the lubricant composition for bottle conveyors of the present invention, the above-mentioned adverse effect appears remarkably, so the addition amount of the anionic surfactant must be limited. Further, when a nonionic surfactant, a cationic surfactant, or an amphoteric surfactant other than the component (B) is used instead of the component (B), the lubricity may be deteriorated or the lubricity may be maintained for a long time. Since it may not be possible, these cannot be used as component (B). However, even when a nonionic surfactant, a cationic surfactant, or an amphoteric surfactant other than the component (B) is added to the lubricant composition for bottle conveyors of the present invention, it is not as bad as an anionic surfactant. Therefore, nonionic surfactants other than the component (B), cationic surfactants, and amphoteric surfactants can be added to the lubricant composition for bottle conveyors of the present invention.

角底、５００ｍｌ容積のポリエチレンテレフタレート（ＰＥＴ）製容器を置き、ボトルコンベアスピード３０ｍ／分の樹脂コンベア上に、潤滑剤を６０ｍｌ／分の量で３０秒間噴霧した後、直後の摩擦係数（付着直後）と、噴霧終了１０分後と、噴霧終了６０分後の乾燥時の摩擦係数（乾燥後）を測定した。なお、摩擦係数は、ＰＥＴ製容器と荷重測定器を連結させ、コンベア稼動中の引張り荷重値を測定し、以下の計算式より算出したものである。
摩擦係数（μ）＝引張り荷重（ｇ）／ＰＥＴ製容器重量（ｇ）
潤滑性評価方法
−：摩擦係数（μ）＝０．０８未満（滑りすぎのため制御不能）
○：摩擦係数（μ）＝０．０８以上０．１０未満（滑りが良好）
△：摩擦係数（μ）＝０．１０以上０．１２未満（摩擦係数が若干高いが、使用することは可能）

(1) Lubrication test Immediately after placing a container made of polyethylene terephthalate (PET) having a square bottom and a volume of 500 ml and spraying a lubricant at a rate of 60 ml / min for 30 seconds on a resin conveyor at a bottle conveyor speed of 30 m / min. The coefficient of friction (immediately after adhesion), the coefficient of friction at the time of drying 10 minutes after the end of spraying and 60 minutes after the end of spraying (after drying) were measured. The friction coefficient is calculated from the following calculation formula by connecting a PET container and a load measuring device, measuring a tensile load value during operation of the conveyor.
Coefficient of friction (μ) = tensile load (g) / PET container weight (g)
Lubricity evaluation method-: Friction coefficient (μ) = less than 0.08 (cannot be controlled due to slipping too much)
○: Friction coefficient (μ) = 0.08 or more and less than 0.10 (good sliding)
Δ: Friction coefficient (μ) = 0.10 or more and less than 0.12 (Friction coefficient is slightly high, but can be used)
