Resin polymers based on styrene / acrylic copolymer latex or the like are used as protective polishes for flooring floors in houses and synthetic resin floor materials. Patent Document 1 discloses a polishing agent using a polyalkoxylated linear aliphatic alcohol as a leveling agent. Patent Document 2 also describes that the addition of polyethoxylated aliphatic secondary alcohol improves the spreadability and leveling properties. Further, there are Patent Documents 3 to 5 as floor polishing detergents that can impart a cleaning power to the floor polish and remove stains with a single wiping, and can also perform polishing. According to Patent Document 3, by using a volatile amino alcohol, it is possible to obtain a glossy cleaning agent that has a good odor and excellent cleanability and usability. According to Patent Document 4, it is possible to obtain a polishing detergent having both cleaning properties, gloss and scratch resistance by using polyethylene wax, polypropylene wax and alkanolamine. On the other hand, according to Patent Document 5, it is said that a glossy cleaning agent having both cleaning properties and gloss and slip resistance can be obtained without using an alkali agent such as alkanolamine.

つや出し洗浄剤においては、洗浄性とつや出し性能は重要であるが、それに加えて、重ね塗りする場合にもきれいなつやが得られること、さらに、つや出し剤を塗布した床の耐水性、すなわち水をこぼしてその上に摩擦力がかかるような場面があってもムラや曇りを生じない、といった性能を併せ持つことも要求される。特許文献3、特許文献4に示されているようなつや出し洗浄剤は、アルカリ成分を含有するために、ポリマー樹脂膜を膨潤させて膜表面を薄く溶解させることも期待できるため高い洗浄性を示すが、その一方で、生乾きのうちに重ね塗りをすると、乾燥不十分な膜が重ね塗られたつや出し洗浄液によって部分的に溶解し、重ね塗りで期待される高いつやが出るどころか、反対に曇りが生じることがある。これを回避するためにアルカリ剤を低減させると、今度は汚れに対する洗浄性も低下してしまう。これを補うために界面活性剤を添加あるいは増量することが考えられるが、単純に界面活性剤を増やすだけでは、洗浄性と得られた樹脂膜の耐水性の両立は困難であった。すなわち、特許文献5で用いられているようなエチレンオキサイド付加モル数が10以上といった比較的付加モル数の多いエチレンオキサイド型非イオン界面活性剤を用いると、洗浄性は向上するが耐水性が低下し、逆に、特許文献1や特許文献2で用いられているような、エチレンオキサイド付加モル数が3程度といった比較的付加モル数の少ないエチレンオキサイド型非イオン界面活性剤を用いると、膜の耐水性はよいが、洗浄性の不足が目立ってしまう。   In polish cleaners, cleanability and polish performance are important, but in addition to that, it is possible to obtain a clean gloss even when overcoated, and the water resistance of the floor to which the polish is applied, i.e. spilling water. In addition, even if there is a scene where a frictional force is applied on it, it is also required to have a performance that does not cause unevenness or cloudiness. Since the polishing detergents shown in Patent Document 3 and Patent Document 4 contain an alkaline component, they can be expected to swell the polymer resin film and dissolve the film surface thinly, thus exhibiting high detergency. On the other hand, when overcoating while being dry, the film with insufficient drying is partially dissolved by the overcoated glossy cleaning solution, and on the contrary, the high gloss expected by overcoating is produced, and on the contrary, cloudy May occur. If the alkaline agent is reduced in order to avoid this, the detergency against dirt is also lowered. In order to compensate for this, it is conceivable to add or increase the amount of a surfactant. However, simply increasing the surfactant makes it difficult to achieve both cleanability and water resistance of the resulting resin film. That is, when an ethylene oxide type nonionic surfactant having a relatively large number of added moles, such as the number of moles of ethylene oxide added as used in Patent Document 5, is used, the detergency is improved but the water resistance is lowered. On the other hand, when an ethylene oxide type nonionic surfactant having a relatively small number of added moles, such as the number of moles of ethylene oxide added, as used in Patent Document 1 or Patent Document 2, is used, Water resistance is good, but lack of cleanliness is noticeable.

従って本発明の目的は、洗浄性及びつや出し性能に優れ、更には、重ね塗りした場合にも曇りが生じにくく、耐水性の高い樹脂膜を形成する、という4つの性質を併せ持つ、床用つや出し洗浄剤組成物を提供することにある。   Therefore, the object of the present invention is excellent in cleaning properties and polish performance, and further, when coated again, it is difficult to cause fogging and forms a highly water-resistant resin film. It is to provide an agent composition.

In order to obtain gloss, the average EO addition mole number is preferably 0.5 to 5, more preferably 0.5 to 3.5. As the component (b), polyoxyethylene 2-ethylhexyl ether (average EO addition mole number 1 to 5) and polyoxyethylene lauryl ether (primary or secondary, average EO addition mole number 1 to 5) are preferable.

<(C) component>
Component (c) is a polyoxyethylene alkyl ether having an average EO addition mole number of 5.5 or more and 15 or less, and the alkyl group preferably has 8 to 22 carbon atoms, more preferably 10 to 18 carbon atoms. The alkyl group may be linear or branched, but the alkyl group is preferably a saturated hydrocarbon. The EO addition type is not limited to the first grade, and may be a second grade or high grade. In order to obtain detergency, the average number of added EO moles is preferably 6 to 15, more preferably 6 to 12. As the component (c), polyoxyethylene 2-ethylhexyl ether (average EO addition mole number 6 to 12) and polyoxyethylene lauryl ether (primary or secondary, average EO addition mole number 6 to 12) are preferable. In addition, it is preferable that the difference of the average EO addition mole number of (b) component and (c) component is 0.5 or more.

(b)成分と(c)成分の合計含有量が少なすぎると十分な洗浄力及び光沢が得られず、多すぎると耐水性に劣る。そのため、本発明の床用つや出し洗浄剤組成物は、洗浄力、光沢及び耐水性のバランスの観点から、(b)成分と(c)成分の合計含有量が(b)+(c)=0.01〜2重量%であり、好ましくは0.2〜1.5重量%、更に好ましくは0.25〜1.25重量%である。また、同じく洗浄力、光沢及び耐水性のバランスの観点から、(b)成分と(c)成分の重量比は、(b)/(c)=0.5〜10であり、好ましくは0.8〜8、更に好ましくは1〜5である。   If the total content of the component (b) and the component (c) is too small, sufficient detergency and gloss cannot be obtained, and if too large, the water resistance is poor. Therefore, the floor polish cleaning composition of the present invention has a total content of (b) component and (c) component of (b) + (c) = 0 from the viewpoint of the balance of detergency, gloss and water resistance. 0.01 to 2% by weight, preferably 0.2 to 1.5% by weight, and more preferably 0.25 to 1.25% by weight. Similarly, from the viewpoint of the balance of detergency, gloss and water resistance, the weight ratio of the component (b) to the component (c) is (b) / (c) = 0.5-10, preferably 0.8. It is 8-8, More preferably, it is 1-5.

この比率を満たした上で、本発明の床用つや出し洗浄剤組成物における(b)成分の含有量は、0.1〜1.5重量%、更に0.2〜1.0重量%の範囲から選択されることが好ましく、また、(c)成分の含有量は、0.05〜1.0重量%、更に0.1〜0.7重量%の範囲から選択されることが好ましい。   After satisfying this ratio, the content of the component (b) in the polishing polish composition for floor of the present invention is in the range of 0.1 to 1.5% by weight, more preferably 0.2 to 1.0% by weight. The content of component (c) is preferably selected from the range of 0.05 to 1.0% by weight, more preferably 0.1 to 0.7% by weight.

本発明によれば(b)成分を含有することで、洗浄力のみならず光沢も向上する。このメカニズムについては定かではないが、平均EO付加モル数の比較的小さい非イオン界面活性剤である(b)成分が、従来多用されていたトリブトキシエチルフォスフェートのような可塑剤として樹脂膜中に残留し、造膜性向上、レベリング性向上等に働き、結果的に光沢の増加に関与しているものと推定される。平均EO付加モル数の比較的大きい非イオン界面活性剤である(c)成分は洗浄力向上には効果的ではあるが、過剰に用いると膜の耐水性低下につながる。本発明は平均EO付加モル数の異なる非イオン界面活性剤を組み合わせて用いることで、従来は得られなかった洗浄力、光沢、耐水性、及び重ね塗りをした場合にも曇りが生じにくいといったバランスのとれた床用つや出し洗浄剤組成物が得られたものと考えられる。   According to the present invention, by including the component (b), not only detergency but also gloss is improved. Although it is not clear about this mechanism, the component (b), which is a nonionic surfactant having a relatively small average EO addition mole number, is used as a plasticizer such as tributoxyethyl phosphate in the resin film. It is presumed that it remains in the film and works to improve film-forming properties, leveling properties, etc., and as a result, is involved in the increase in gloss. The component (c), which is a nonionic surfactant having a relatively large average EO addition mole number, is effective in improving the detergency, but if used in excess, it leads to a decrease in water resistance of the membrane. The present invention uses a combination of nonionic surfactants having different average EO addition mole numbers, and has a balance that has not been obtained in the past, such as detergency, gloss, water resistance, and that even when overcoated, fogging is unlikely to occur. It is considered that a smooth polishing composition for floor was obtained.

<床用つや出し洗浄剤組成物>
本発明の床用つや出し洗浄剤組成物は、造膜性向上、光沢向上、洗浄力向上の観点から、更に、(d)水溶性溶剤を含有することが好ましい。(d)成分としては、エチルカルビトール、ブチルカルビトール、モノエタノールアミン、モノプロパノールアミン、エタノール、プロパノール、等が挙げられ、なかでも、エチルカルビトール、モノエタノールアミン、エタノールが好ましい。(d)成分としてこれらの中から選ばれる1種以上の水溶性溶剤を、組成物中に合計として、0.5〜10重量%、更に2〜8重量%含有することが好ましい。なお、モノエタノールアミン、モノプロパノールアミンといったアルカノールアミン類は、洗浄力及び光沢の向上に大きな効果を示すが、過剰に含有させると、重ね塗りをした場合に曇りを生じる場合がある。これは過剰なアルカノールアミン類によって床用つや出し洗浄剤組成物全体のpHが上がり、膜を構成する樹脂がアルカリ性に弱い場合に、下地の樹脂膜を過度に荒らしてしまうためであると考えられる。これを防ぐために、アルカノールアミン類の含有量は、組成物中、好ましくは0.5重量%以下、さらに好ましくは0.3重量%以下である。
<Finishing detergent composition for floor>
The polishing polish composition for floors of the present invention preferably further contains (d) a water-soluble solvent from the viewpoint of improving the film forming property, improving the gloss, and improving the detergency. Examples of the component (d) include ethyl carbitol, butyl carbitol, monoethanolamine, monopropanolamine, ethanol, propanol, etc. Among them, ethylcarbitol, monoethanolamine, and ethanol are preferable. As the component (d), one or more water-soluble solvents selected from these are preferably contained in the composition in an amount of 0.5 to 10% by weight, more preferably 2 to 8% by weight. In addition, although alkanolamines such as monoethanolamine and monopropanolamine have a great effect on improvement of detergency and gloss, if they are contained excessively, they may be clouded when overcoated. This is presumably because excessive alkanolamines raise the pH of the entire polishing polish composition for flooring and excessively roughen the underlying resin film when the resin constituting the film is weakly alkaline. In order to prevent this, the content of alkanolamines in the composition is preferably 0.5% by weight or less, more preferably 0.3% by weight or less.

上記と同様に、膜を構成する樹脂がアルカリ性に弱い場合には、耐水性を得る観点及び重ね塗りをしても曇りを生じにくいという観点から、本発明の床用つや出し洗浄剤組成物は、25℃におけるpHが6.0〜11.0、更に6.0〜9.0、より更に6.0〜8.0であることが好ましい。   Similarly to the above, when the resin constituting the film is weak in alkalinity, from the viewpoint of obtaining water resistance and being less likely to cause fogging even if it is overcoated, the floor polishing detergent composition of the present invention is The pH at 25 ° C is preferably 6.0 to 11.0, more preferably 6.0 to 9.0, and still more preferably 6.0 to 8.0.

Other components that can be blended include oxidized polyethylene wax, oxidized polypropylene wax, silicone oil, modified silicone, preservatives, and fragrances.

本発明の床用つや出し洗浄剤組成物は、上記(a)〜(c)成分、更に必要に応じて配合される(d)成分やその他の成分と、水とを含有する。水の含有量は、組成物中60〜98重量%、更に80〜95重量%が好ましい。   The floor polish cleaning composition of the present invention contains the above components (a) to (c), the component (d) and other components blended as necessary, and water. The water content is preferably 60 to 98% by weight, more preferably 80 to 95% by weight in the composition.

That is, when the composition is applied to the floor a plurality of times, even when the composition is further applied in a state where the application interval is short and the composition is not sufficiently dried (freshly dried state) Higher gloss effect is exhibited by. Therefore, according to the present invention, there is provided a method for polishing floor polishing, wherein the floor polishing detergent composition of the present invention, preferably a composition having a pH of 6.0 to 8.0 at 25 ° C, is applied to the floor a plurality of times.

表1の床用つや出し洗浄剤組成物を調製し、下記の評価方法により洗浄力、光沢増分、耐水性、及び重ね塗り耐性を調べた。結果を表1に示す。
<評価方法>
(1)洗浄力
市販のバターをクロロホルムで10%に希釈した液に、SUS304試験片(JIS G4305)を浸漬後、試験片表面が液面に対して垂直になるように過剰な液を落としながらゆっくりと引き上げる。これを乾燥させて薄く均一なバター膜を形成し、モデル汚れプレートとする。モデル汚れプレートに床用つや出し洗浄剤組成物を滴下し、10秒後にミスト状にイオン交換水を噴霧し、機械力を与えないように注意しながら床用つや出し洗浄剤組成物を洗い流す。操作後、床用つや出し洗浄剤組成物を滴下した部分の面積に対するバターが除去された面積の比(%)を求め、その値をもって洗浄力の指標とした。
The floor polish compositions for floors shown in Table 1 were prepared, and the detergency, gloss increment, water resistance, and overcoat resistance were examined by the following evaluation methods. The results are shown in Table 1.
<Evaluation method>
(1) Detergency After immersing SUS304 test piece (JIS G4305) in a solution of commercial butter diluted to 10% with chloroform, dropping excess liquid so that the test piece surface is perpendicular to the liquid surface Pull it up slowly. This is dried to form a thin and uniform butter film to obtain a model dirt plate. The floor polishing detergent composition is dropped onto the model dirt plate, and after 10 seconds, ion exchange water is sprayed in a mist form, and the floor polishing detergent composition is washed away so as not to give mechanical force. After the operation, the ratio (%) of the area from which the butter was removed to the area of the portion where the polished polishing composition for floor was dropped was determined, and the value was used as an index of cleaning power.

(2)光沢増分
光沢増分は、スガ試験機株式会社製デジタル変角光沢計UGV−5D型を用い、入射角と反射角をともに60°に設定して、松下電工製フローリングKEC12UEに対して、塗布前と、床用つや出し洗浄剤組成物の塗布と乾燥を3回繰り返した後の光沢の差を求めることによって得た。光沢増分が大きいほど、ワックス効果に優れることを意味する。
(2) Gloss increment The gloss increment is a digital variable angle gloss meter UGV-5D manufactured by Suga Test Instruments Co., Ltd., and both the incident angle and the reflection angle are set to 60 °. It was obtained by determining the difference in gloss before application and after repeating the application and drying of the polishing polish composition for floor three times. The larger the gloss increment, the better the wax effect.

(3)耐水性
25℃/相対湿度40%の環境下で、松下電工製フローリングKEC12UEに床用つや出し洗浄剤組成物を塗布し、所定時間乾燥後に、イオン交換水を0.1mL滴下して5分後に折りたたんだティッシュで強く拭き取る操作を行う。イオン交換水の拭き取り跡が残らなくなるまでの最低乾燥時間(時間)を耐水性の指標とした。値が小さいほど耐水性に優れることを意味しており、具体的には該床用つや出し洗浄剤組成物を塗布した後、乾燥時間を長時間とらなくても、床にこぼしてしまった水を拭き取るといった日常生活での使用に耐えることを意味している。
(3) Water resistance Under an environment of 25 ° C./40% relative humidity, floor polish KEC12UE manufactured by Matsushita Electric Works was applied with a floor polish cleaning composition, dried for a predetermined time, and then 0.1 mL of ion-exchanged water was dropped. Do a strong wipe with a folded tissue after a minute. The minimum drying time (hours) until no wiping trace of ion-exchanged water remains was used as an index of water resistance. The smaller the value, the better the water resistance. Specifically, after applying the floor polish cleaning composition, water that has spilled on the floor can be removed without taking a long drying time. It means that it can withstand daily use such as wiping.

(4)重ね塗り耐性
25℃/相対湿度40%の環境下で、松下電工製フローリングKEC12UEに床用つや出し洗浄剤組成物を塗布し、塗布終了後1分間隔で最大10分後まで、同じ部分に床用つや出し洗浄剤組成物を再度塗布する。前述の光沢測定を行い、再度塗布による光沢の低下が起こらない最低乾燥時間(分)を重ね塗り耐性の指標とした。値が小さいほど重ね塗り耐性に優れることを意味しており、具体的には該床用つや出し洗浄剤組成物を塗布した後、重ね塗りをする場合にも、乾燥時間を長時間とらなくても、最初に塗布した下地の表面を荒らさず、曇りを生じるなどの悪影響を及ぼしにくいことを意味している。重ね塗りをする場面としては、一度該床用つや出し洗浄剤組成物を塗布した後さらに高い光沢を求める場合、あるいは、塗り残し部分を発見して追加で該床用つや出し洗浄剤組成物を使用したい場合にやむを得ず重ね塗り部分が生じてしまう場合、などが考えられる。これらの重ね塗りの必要な場面は決して例外的なものではなく、床用つや出し洗浄剤組成物が兼ね備えるべき重要な特性と考えられる。
(4) Overcoat resistance Under the environment of 25 ° C / 40% relative humidity, apply the floor polish cleaner composition to the flooring KEC12UE made by Matsushita Electric Works, and the same part up to 10 minutes at intervals of 1 minute after the application is completed Apply again the floor polish cleaning composition. The gloss measurement described above was carried out, and the minimum drying time (minutes) at which the gloss did not deteriorate again due to coating was used as an index for the overcoat resistance. The smaller the value, the better the resistance to repeated coating. Specifically, even after applying the polishing polish composition for flooring, even when performing repeated coating, it does not take a long drying time. This means that the surface of the base applied first is not roughened, and does not adversely affect such as cloudiness. In the case of overcoating, if you want to obtain a higher gloss after applying the floor polish cleaning composition once, or if you want to use the floor polish cleaning composition after discovering the unpainted area In such a case, a case where an overcoated portion is unavoidable may be considered. These scenes requiring recoating are by no means exceptional and are considered important properties that must be combined with a floor polish composition.

(注)表中の重量%は有効分の濃度を示す(以下同様)。 (Note) The weight% in the table indicates the concentration of the effective component (the same applies hereinafter).

表1より、(b)+(c)、(b)/(c)が、それぞれ特定範囲にある場合に洗浄力、高光沢、耐水性、及び重ね塗り耐性という4つの性質を併せもつことがわかる。特許文献2の実施例にあるように、界面活性剤として(b)成分のみ含有する比較例1では実施例1と比較して十分な洗浄力が得られないことがわかる。比較例2のように異なる(b)成分を組み合わせても大きな改善は見られない。反対に比較例3のように界面活性剤として(b)成分を用いず異なる(c)成分を組み合わせた場合は、光沢の不足が見られる。特許文献5の実施例にあるように、界面活性剤として平均EO付加モル数の大きな非イオン界面活性剤を用いる比較例4では、洗浄力と光沢の両立はおろか、耐水性の低下も招くこととなる。(b)/(c)の比率が大きすぎる比較例5については、特定比率を保っている実施例3に比べて、洗浄力の不足が見られる。   According to Table 1, when (b) + (c) and (b) / (c) are in specific ranges, they have the four properties of detergency, high gloss, water resistance, and overcoat resistance. Recognize. As shown in the Examples of Patent Document 2, it can be seen that Comparative Example 1 containing only the component (b) as a surfactant does not provide sufficient detergency compared to Example 1. Even when different components (b) are combined as in Comparative Example 2, no significant improvement is observed. On the other hand, when the component (b) is not used as a surfactant and a different component (c) is combined as in Comparative Example 3, a lack of gloss is observed. As shown in the Examples of Patent Document 5, Comparative Example 4 using a nonionic surfactant having a large average EO addition mole number as a surfactant not only achieves both cleaning power and gloss, but also causes a decrease in water resistance. It becomes. In Comparative Example 5 in which the ratio of (b) / (c) is too large, the cleaning power is deficient as compared with Example 3 in which the specific ratio is maintained.

表2は一律にモノエタノールアミンを0.1重量%含有する弱アルカリの系について評価をまとめた。表1の実施例1〜4(中性系)と表2の実施例5〜8との比較から、耐水性及び重ね塗り耐性については実施例1〜4の中性系でより良好であり、洗浄力及び光沢については実施例5〜8の弱アルカリ系でより良好であることがわかる。   Table 2 summarizes the evaluation of weakly alkaline systems containing 0.1% by weight monoethanolamine. From comparison between Examples 1 to 4 (neutral system) in Table 1 and Examples 5 to 8 in Table 2, water resistance and overcoat resistance are better in the neutral system of Examples 1 to 4, It can be seen that the detergency and gloss are better in the weak alkaline systems of Examples 5-8.

また、(b)成分と(c)成分を特定比率で併用している実施例5に対して、(c)成分のみ含有し(b)成分を含有しない比較例6は光沢及び耐水性で劣ることがわかる。(c)成分の含有量を2倍にした比較例7についても、同じく光沢及び耐水性の不足が見られる。(b)/(c)の比率が大きすぎる比較例8については、特定比率を保っている実施例6に比べて、洗浄力の不足が見られる。比較例9のように(b)/(c)の比率が本発明の範囲であっても、(b)+(c)の総量が過多の場合は耐水性の低下が見られる。   Moreover, compared with Example 5 which uses (b) component and (c) component together by specific ratio, the comparative example 6 which contains only (c) component and does not contain (b) component is inferior in glossiness and water resistance. I understand that. Regarding Comparative Example 7 in which the content of the component (c) is doubled, the gloss and water resistance are similarly insufficient. In Comparative Example 8 in which the ratio of (b) / (c) is too large, the cleaning power is insufficient as compared with Example 6 in which the specific ratio is maintained. Even when the ratio of (b) / (c) is within the range of the present invention as in Comparative Example 9, when the total amount of (b) + (c) is excessive, a decrease in water resistance is observed.
