Abstract
Description
本発明は、塩化カルシウム（ＣａＣｌ２ ）を含有する汚れに対して効果的な洗浄剤に関する。 The present invention relates to a cleaning agent effective against soil containing calcium chloride (CaCl 2 ).
従来、油汚れに適する洗浄力を発揮する洗浄剤として、炭素原子４〜１０の脂肪族アルコールのアルキレンオキシド３〜１０モル付加物を含有する洗浄剤が提案されていた（たとえば特許文献１参照）。 Conventionally, a detergent containing 3 to 10 mol of an alkylene oxide adduct of an aliphatic alcohol having 4 to 10 carbon atoms has been proposed as a detergent that exhibits a detergency suitable for oil stains (see, for example, Patent Document 1). .
寒冷地などのように融雪剤としてＣａＣｌ２ が大量に散布されている道路を走行した自動車に付着した長期に亘って蓄積された汚れは、多くの場合、水垢、土砂、油分などの複合的な汚れ成分のほかにＣａＣｌ２ を含有している。そのため、このような自動車の車体の洗浄に適する洗浄剤には、水垢、土砂、油分などの複合的な汚れ成分を洗い流すという洗浄作用と共に、ＣａＣｌ２ に対する洗浄力を発揮することが要求されるだけでなく、ＣａＣｌ２ は自動車の車体に付着したまま放置されることによって錆を発生させやすいものであるために強い防錆力を発揮することも要求されている。 Dirt accumulated over a long period of time on automobiles traveling on roads where a large amount of CaCl 2 is applied as a snow melting agent, such as in cold regions, is often complex such as scale, earth and sand, and oil. In addition to the soil component, CaCl 2 is contained. Therefore, such a cleaning agent suitable for cleaning a car body of an automobile is only required to exhibit a detergency against CaCl 2 in addition to a cleaning action of washing away composite dirt components such as scale, earth and sand, and oil. In addition, since CaCl 2 is liable to generate rust by being left on the body of an automobile, it is also required to exert a strong rust preventive power.
しかしながら、上掲の特許文献１に見られる洗浄剤は、主に油汚れを対象としているだけであるに過ぎず、汚れに含有されるＣａＣｌ２ に対する洗浄力や防錆力については考慮されていない。 However, the cleaning agent found in the above-mentioned Patent Document 1 is only mainly intended for oil stains, and does not take into consideration the cleaning power and rust prevention power against CaCl 2 contained in the soil. .
本発明は以上の状況の下でなされたものであり、防錆作用とＣａＣｌ２ に対する洗浄作用とを発揮する自動車車体用洗浄剤を提供することを目的とする。 The present invention has been made under the above circumstances, and an object of the present invention is to provide a vehicle body cleaning agent that exhibits rust prevention and CaCl 2 cleaning.
また、本発明は、防錆作用とＣａＣｌ２ に対する洗浄作用とを発揮するだけでなく、一般的な洗剤のように水垢、土砂、油分などの複合的な汚れ成分に対する洗浄作用をも発揮する自動車車体用洗浄剤を提供することを目的とする。 In addition, the present invention not only exhibits a rust-preventing action and a cleaning action against CaCl 2 , but also exhibits a cleaning action against complex dirt components such as scales, earth and sand, and oil as in general detergents. It aims at providing the cleaning agent for vehicle bodies.
さらに、本発明は、洗車によって汚れ成分中のＣａＣｌ２ が洗い流されたか否かを目視によって容易に確認することのできる自動車車体用洗浄剤を提供することを目的とする。 Furthermore, an object of the present invention is to provide a vehicle body cleaning agent that can easily visually confirm whether or not CaCl 2 in a dirt component has been washed away by car washing.
さらに、本発明は、車体塗装面の研磨が洗車時に同時に行われる自動車車体用洗浄剤を提供することを目的とする。 Furthermore, an object of the present invention is to provide a vehicle body cleaning agent in which polishing of a painted surface of a vehicle body is performed at the same time as washing.
本発明に係る自動車車体用洗浄剤は、塩化カルシウムキャッチャーとして防錆効果を有する活性剤を配合したものである。この発明において、活性剤としての塩化カルシウムキャッチャーは、汚れ成分中のＣａＣｌ２ を捕捉する作用を発揮するものであればよく、望ましくは、汚れ成分中の塩化カルシウムと反応することにより視認可能な白沈を生じさせる化合物である。このように汚れ成分中のＣａＣｌ２ と反応して視認可能な白沈を生じさせる化合物を活性剤として用いると、洗車時に作業者が車体面の白沈の有無を視認できたか否かを尺度として、汚れ成分中のＣａＣｌ２ が洗浄によって洗い流されたか否かを容易に判断することが可能になる。また、１回の洗車作業によって車体面に白沈が視認されたときには、その白沈が視認されなくなるまで再度の洗車作業を繰り返すことによって確実にＣａＣｌ２ を洗い流すことができるようになり、併せて、残留ＣａＣｌ２ による車体の発錆を未然に防止することが可能になる。 The automobile body cleaner according to the present invention is a mixture of an activator having a rust prevention effect as a calcium chloride catcher. In the present invention, the calcium chloride catcher as the activator is not limited as long as it exhibits an action of trapping CaCl 2 in the soil component, and is desirably white that can be visually recognized by reacting with calcium chloride in the soil component. It is a compound that causes precipitation. When a compound that reacts with CaCl 2 in the dirt component to cause visible white sediment is used as an activator, whether or not the worker can visually recognize the presence or absence of white sediment on the vehicle surface during car washing is used as a scale. It becomes possible to easily determine whether or not CaCl 2 in the dirt component has been washed away. In addition, when white sink is visually recognized on the vehicle body surface by one car wash operation, CaCl 2 can be reliably washed away by repeating the car wash operation until the white sink is no longer visible. Further, it is possible to prevent rusting of the vehicle body due to residual CaCl 2 .
本発明において、前記活性剤は、アルキルホスフェートであっても、アルキルホスフェート及び石けんの２種を含んでいてもよい。すなわち、本発明に係る自動車車体用洗浄剤には、活性剤としてアルキルホスフェートだけが含有されていても、アルキルホスフェートと石けんとの両方が含有されていてもよい。 In the present invention, the activator may be an alkyl phosphate or two kinds of alkyl phosphate and soap. That is, the automobile body cleaner according to the present invention may contain only alkyl phosphate as an activator, or may contain both alkyl phosphate and soap.
アルキルホスフェートは正リン酸にアルキル基が導入されている有機リン化合物であり、有機置換基の数に応じてモノエステル、ジエステル、トリエステルなどに分類される。本発明において、活性剤としてのアルキルホスフェートには、いずれのエステルをも用いることができるが、モノエステルが好適である。それらのいずれを用いるかは当該洗浄剤に具備させるべき性質、言い換えると汚れ成分中のＣａＣｌ２ の除去の他に意図する目的及び用途によって適宜選択されるべきである。たとえば、モノエステルは車体面に制電性や汚れにくい性質を備えさせるのに適している。 Alkyl phosphates are organic phosphorus compounds in which an alkyl group is introduced into orthophosphoric acid, and are classified into monoesters, diesters, triesters and the like according to the number of organic substituents. In the present invention, any ester can be used for the alkyl phosphate as the activator, but a monoester is preferred. Which of these should be used should be appropriately selected according to the property to be provided in the cleaning agent, in other words, the intended purpose and use in addition to the removal of CaCl 2 from the soil component. For example, monoester is suitable for providing the vehicle body surface with antistatic properties and resistance to contamination.
また、アルキルホスフェートは市販品として入手可能であるので、活性剤としてアルキルホスフェートを用いることは活性剤の入手が容易であるという利点を発揮する。アルキルホスフェートは市販品には、たとえば、フォスファノールＭＬ−２００、あるいは、ＭＬ−２２０などがある。これらはいずれも商品名であり、東邦化学工業（株）よって提供されている。 In addition, since alkyl phosphate is available as a commercial product, the use of alkyl phosphate as the activator exhibits the advantage that the activator is easily available. Examples of commercially available alkyl phosphates include phosphanol ML-200 and ML-220. These are trade names and are provided by Toho Chemical Industry Co., Ltd.
アルキルホスフェートのモノエステル比率は、たとえば３０〜９５重量％、好ましくは５０〜９０重量％である。３０重量％より少ないと洗浄力が劣り、９５％より多いものは工業的に生産するのが難しい。アルキルホスフェートのアルキル基の炭素数は、たとえばＣ3 〜Ｃ24、好ましくはＣ8 〜Ｃ18である。Ｃ3未満ではカルシウム捕捉能が不足し、Ｃ24以上では洗浄力が悪化する。Ｃ3 〜Ｃ24であると、良好な洗浄性を示し、しかも、満足のいくカルシウム捕捉能を発揮してＣａＣｌ２ キャッチャーとしての役割を十分に担うようになる。この傾向は、Ｃ8〜Ｃ18である場合に特に顕著に発揮される。なお、アルキルホスフェートには、ホスフェートＫ塩、同Ｎａ塩、同アミン塩などがあり、本発明では、これらのいずれも用いることができる。 The monoester ratio of the alkyl phosphate is, for example, 30 to 95% by weight, preferably 50 to 90% by weight. If it is less than 30% by weight, the detergency is inferior, and if it is more than 95%, it is difficult to produce industrially. The carbon number of the alkyl group of the alkyl phosphate is, for example, C 3 to C 24 , preferably C 8 to C 18 . Insufficient calcium trapping ability is less than C 3, detergency deteriorates the C 24 or higher. When it is C 3 to C 24 , good detergency is exhibited, and satisfactory calcium scavenging ability is exhibited to sufficiently play a role as a CaCl 2 catcher. This tendency is particularly remarkable when it is C 8 to C 18 . The alkyl phosphate includes phosphate K salt, sodium salt, amine salt and the like, and any of these can be used in the present invention.
防錆効果を有するＣａＣｌ２ キャッチャーとしてアルキルホスフェートに加えて、石けんを配合することにより、ＣａＣｌ２ の視認性及び防錆性が向上する。石けんは脂肪酸とアルカリの反応物であり、アルカリの種類により、カリウム石けん、ナトリウム石けん、アミン石けんなどに分類される。本発明では、これらのいずれも用いることができる。 In addition to alkyl phosphate as a CaCl 2 catcher having a rust preventive effect, the visibility and rust preventive properties of CaCl 2 are improved by blending soap. Soap is a reaction product of fatty acid and alkali, and is classified into potassium soap, sodium soap, amine soap, etc., depending on the type of alkali. Any of these can be used in the present invention.
石けんのアルキル基の炭素数は、たとえばＣ6〜Ｃ24、好ましくはＣ8 〜Ｃ18である。Ｃ6未満ではカルシウム捕捉能が不足し、Ｃ24を超えると洗浄性が悪化する。Ｃ6〜Ｃ24であると、カルシウム捕捉能及び洗浄性が共に満足のいく程度に満たされ、Ｃ8 〜Ｃ18では特に優れたカルシウム捕捉能及び洗浄性を示す。 The carbon number of the alkyl group of the soap is, for example, C 6 to C 24 , preferably C 8 to C 18 . If it is less than C 6 , the calcium scavenging ability is insufficient, and if it exceeds C 24 , the detergency deteriorates. When it is C 6 to C 24 , both the calcium scavenging ability and detergency are satisfied to a satisfactory degree, and C 8 to C 18 exhibit particularly excellent calcium scavenging ability and detergency.
防錆効果を有するＣａＣｌ２ キャッチャーであるアルキルホスフェートの配合割合は、ＣａＣｌ２ シャンプー（当該洗浄剤）１００に対して０．０１〜８０重量部、好ましくは０．０５〜３０重量部である。０．０１未満ではカルシウム捕捉能が不足し、８０を超えると乳化安定性、作業性が悪化する。０．０１〜８０重量部であると、カルシウム捕捉能及び乳化安定性、作業性が共に満足のいく程度に満たされ、０．０５〜３０重量部であると、特に優れた作業性及び乳化安定性を示す。また、石けんを含有させる場合、その配合割合は当該洗浄剤１００に対して１０重量部以下、好ましくは５重量部以下である。１０を超えると、汚れのこびりつき度合が悪化する。 The compounding ratio of the alkyl phosphate which is a CaCl 2 catcher having a rust preventive effect is 0.01 to 80 parts by weight, preferably 0.05 to 30 parts by weight with respect to 100 of the CaCl 2 shampoo (the cleaning agent). If it is less than 0.01, the calcium capturing ability is insufficient, and if it exceeds 80, the emulsion stability and workability deteriorate. When the amount is 0.01 to 80 parts by weight, the calcium capturing ability, the emulsion stability, and the workability are satisfied to a satisfactory level. When the amount is 0.05 to 30 parts by weight, the workability and the emulsion stability are particularly excellent. Showing gender. Moreover, when it contains soap, the mixture ratio is 10 weight part or less with respect to the said washing | cleaning agent 100, Preferably it is 5 weight part or less. If it exceeds 10, the degree of dirt sticking deteriorates.
本発明に係る自動車車体用洗浄剤は、ｐＨが６〜８であることが望ましく、ｐＨが６〜８の中性域にあると、車体面が洗浄剤に侵されるという事態が起こらず、汚れのこびりつきも起こりにくく、また、環境への負荷が小さく、洗浄作業による手荒れなどを生じにくくなる。 The vehicle body cleaner according to the present invention preferably has a pH of 6 to 8. If the pH is in the neutral range of 6 to 8, the vehicle body surface will not be affected by the cleaner, and the Sticking is less likely to occur, and the burden on the environment is small, so that rough hands due to cleaning operations are less likely to occur.
本発明に係る自動車車体用洗浄剤は、研磨剤を含有していることが望ましい。研磨剤が含有されていると、蓄積した汚れを洗浄できると同時に、洗浄作業によって活性剤の作用で車体面に発生したＣａＣｌ２ 複合体（白沈）が研磨剤の作用によって車体面を傷付けることなく物理的に取り除かれやすくなる。研磨剤には、アルミナ、珪藻土、シリカ、ケイ酸アルミニウム０．１〜３０重量％など、公知の研磨材を適宜選択して好適に用いることが可能である。 The automobile body cleaner according to the present invention preferably contains an abrasive. If the abrasive is contained, the accumulated dirt can be cleaned, and at the same time, the CaCl 2 complex (white sand) generated on the surface of the vehicle body by the action of the activator by the cleaning work may damage the body surface by the action of the abrasive. Without being physically removed. As the abrasive, a known abrasive such as alumina, diatomaceous earth, silica, 0.1 to 30% by weight of aluminum silicate can be appropriately selected and used suitably.
本発明に係る自動車車体用洗浄剤は、活性剤としてのアルキルホスフェートを用いたもの、または、アルキルホスフェート及び石けんを用いたものでは、それらによる防錆作用とＣａＣｌ２ 複合体の生成作用とを発揮するので、寒冷地などのように融雪剤としてＣａＣｌ２ が大量に散布されている道路を走行した自動車に付着蓄積された汚れ成分中の水垢、土砂、油分だけでなく、ＣａＣｌ２ をも洗い流す上で好適に使用することができてＣａＣｌ２ の作用による車体の発錆を抑制することが可能である。特に、洗浄作業によって生成されたＣａＣｌ２ 複合体（白沈）を視認することができるので、ＣａＣｌ２ が洗浄されたか否かを容易に確認することができるという利点がある。すなわち、ＣａＣｌ２ の自動車の車体への分布の状態や分布の度合が明かとなるので、ＣａＣｌ２ の自動車の車体への分布の状態や分布の度合に応じた洗浄作業、例えばＣａＣｌ２ の付着蓄積の多い箇所を重点的に洗浄するといった洗浄作業を行うことができる。 The automotive body cleaner according to the present invention uses an alkyl phosphate as an activator or uses an alkyl phosphate and a soap, and exhibits a rust preventive action and a CaCl 2 complex generating action. Therefore, in addition to washing away CaCl 2 as well as water, dirt, sand and oil in dirt components accumulated on automobiles traveling on roads where a large amount of CaCl 2 is sprayed as a snow melting agent, such as in cold regions. Therefore, it is possible to suppress rusting of the vehicle body due to the action of CaCl 2 . In particular, since the CaCl 2 complex (white sediment) generated by the cleaning operation can be visually confirmed, there is an advantage that it can be easily confirmed whether or not CaCl 2 has been cleaned. That is, since the apparent degree of state and the distribution of the distribution of the vehicle body of CaCl 2 automobiles, cleaning operation in accordance with the state and degree of distribution of the distribution of the vehicle body of CaCl 2 automobiles, for example, CaCl 2 deposited and accumulated It is possible to perform a cleaning operation such as intensively cleaning a portion having a large amount of water.
また、本発明に係る自動車車体用洗浄剤は、上記した防錆作用とＣａＣｌ２ に対する洗浄作用とを発揮するだけでなく、一般的な洗浄剤のように水垢、土砂、油分などの複合的な汚れ成分に対する洗浄作用をも発揮する。 In addition, the automotive body cleaning agent according to the present invention not only exhibits the above-described rust-preventing action and cleaning action against CaCl 2 , but also a composite such as scale, earth and sand, and oil as in a general cleaning agent. It also exhibits a cleaning action against dirt components.
さらに、研磨剤を含有するものでは、車体の塗装面の研磨が洗車時に同時に行われる。その上、洗浄作業によって活性剤の作用で車体面に発生したＣａＣｌ２ 複合体（白沈）が研磨剤の作用によって車体面を傷付けることなく物理的に取り除かれやすくなるという効果が奏される。 Further, in the case of containing an abrasive, the painted surface of the vehicle body is polished simultaneously with the car wash. In addition, there is an effect that the CaCl 2 complex (white precipitate) generated on the surface of the vehicle body by the action of the activator by the cleaning operation is easily removed physically without damaging the body surface by the action of the abrasive.
また、本発明の自動車車体用洗浄剤には、そのほかに、本発明の優れた効果を阻害しない範囲において、洗浄剤又は保護剤として一般に慣用されている、たとえば粘度調製剤、老化防止剤、紫外線吸収剤、水溶性溶剤、一般の顔料、染料、蛍光顔料などの着色剤、香料、ｐＨ調整剤などの添加剤を、必要に応じて適宜配合することができる。 In addition, the automotive body cleaning agent of the present invention is commonly used as a cleaning agent or a protective agent, as long as it does not impair the excellent effects of the present invention. Additives such as an absorbent, a water-soluble solvent, a colorant such as a general pigment, a dye, and a fluorescent pigment, a fragrance, and a pH adjuster can be appropriately blended as necessary.
