Description
本発明は、熱水による洗浄を高頻度で行う食品工場床に適した水硬性ポリマーセメント組成物に関し、特には熱水と冷水の繰り返し流下による熱衝撃性に優れると共に、落球による耐衝撃性を有し、コンクリート下地表面に厚さ３ｍｍ〜５ｍｍに塗付する水硬性ポリマーセメント組成物に関し、さらには防かび性にも優れる水硬性ポリマーセメント組成物に関する。 The present invention relates to a hydraulic polymer cement composition suitable for a food factory floor that is frequently washed with hot water, and in particular, has excellent thermal shock resistance due to repeated flow of hot water and cold water, and has impact resistance due to falling balls. The present invention relates to a hydraulic polymer cement composition having a thickness of 3 mm to 5 mm applied to a concrete base surface, and further relates to a hydraulic polymer cement composition having excellent antifungal properties.
従来、耐熱水性、耐摩耗性、耐衝撃性に優れる樹脂セメント組成物として、分子量が１０００〜３０００で両末端に水酸基を持ち、側鎖を持つポリエステルポリオールとポリフェニルポリメチルポリイソシアネート並びに水硬性セメントを含む骨材とが配合されていることを特徴とする樹脂セメント組成物が提案されている（特許文献１）。 Conventionally, as a resin cement composition excellent in hot water resistance, abrasion resistance, and impact resistance, a polyester polyol having a molecular weight of 1000 to 3000, having hydroxyl groups at both ends, having side chains, polyphenylpolymethylpolyisocyanate, and hydraulic cement There has been proposed a resin cement composition characterized in that it contains an aggregate containing slag (Patent Document 1).
しかしながら、特許文献１に記載の樹脂セメント組成物は、耐熱水性に優れるとはいっても、あくまで硬化物を９０℃の熱水に２８日間浸漬し、その外観の変化を目視で評価して異常なしと判断するものであり、該評価方法は、実際に例えば食品工場床で行われている熱水による洗浄を模擬的に再現した評価方法ではなく、食品工場床として使用するためには、少なくとも該食品工場床で行われているような熱水による洗浄を模擬的に再現した評価方法を行ったうえで、該評価結果が良好と判断される必要があるという課題がある。 However, although the resin cement composition described in Patent Document 1 is excellent in hot water resistance, the cured product is immersed in hot water at 90 ° C. for 28 days, and changes in its appearance are visually evaluated to find no abnormality. The evaluation method is not an evaluation method that simulates, for example, washing with hot water that is actually performed on a food factory floor, but at least for use as a food factory floor. There is a problem that it is necessary to judge that the evaluation result is good after performing an evaluation method that simulates washing with hot water as is done on a food factory floor.
また、特許文献１に記載の樹脂セメント組成物は、コンクリート下地表面に塗付して硬化後に徐々に色調が白茶けていく場合があるという課題があり、さらには仮に該食品工場床で行われているような熱水による洗浄を模擬的に再現した評価方法により評価すると、防かび性が十分ではないという課題がある。 In addition, the resin cement composition described in Patent Document 1 has a problem that the color tone may gradually fade after application after being applied to the concrete base surface, and further performed on the floor of the food factory. However, when the evaluation is performed by an evaluation method that simulates washing with hot water as described above, there is a problem that the antifungal property is not sufficient.
本発明が解決しようとする課題は、従来よりやや薄い膜厚の３ｍｍ〜５ｍｍ厚さに塗付しても良好な塗付作業性を有し、また食品工場床で行われているような熱水による洗浄を模擬的に再現した評価方法を行っても、該熱水の繰り返し流下によって塗材が剥がれたり割れたりすることが無く、また硬化後に徐々の塗膜表面の色調が白茶けてしまうことが無く、さらには十分な防かび性を有すると共に、該熱水が繰り返し流下することによる耐熱衝撃性に優れ、また重量物が落下しても剥離しないような耐衝撃性を有する水硬性ポリマーセメント組成物を提供することにある。 The problem to be solved by the present invention is that it has good application workability even when applied to a thickness of 3 mm to 5 mm, which is slightly thinner than conventional ones, and heat as is done on food factory floors. Even if an evaluation method that simulates washing with water is performed, the coating material will not be peeled off or cracked due to repeated flowing of the hot water, and the color tone of the coating surface will gradually fade after curing. In addition, it has a sufficient antifungal property, has excellent thermal shock resistance due to repeated flow of hot water, and has impact resistance so that it does not peel off even if a heavy object falls. It is to provide a cement composition.

It is a hydraulic polymer cement composition characterized by that, in addition to these if necessary Pigments and dispersing agents, additives such as defoaming agents can be incorporated.
本発明の水硬性ポリマーセメント組成物に使用される水分散ポリオールは、上記のように、ヒマシ油変性２官能ポリオールとヒマシ油変性３官能ポリオールとビスフェノールＡ骨格を有する４官能ポリオールと希釈剤と乳化剤と水とから成り、希釈剤はアルキルスルホン酸フェニルエステルとフタル酸ジオクチルを含む。特にアルキルスルホン酸フェニルエステルは、水分散ポリオール１００重量部中５〜１５重量部が好ましく、該アルキルスルホン酸フェニルエステルを配合することにより、本組成物をコンクリート下地表面に３〜５ｍｍ厚さに塗付した際、塗材表面に均一な樹脂の浮きを発現させることが出来ると共に、塗付作業性を良好なものとすることができる。市販のアルキルスルホン酸フェニルエステルとしては、メザモール（商品名、バイエル社製）ある。 As described above, the water-dispersed polyol used in the hydraulic polymer cement composition of the present invention includes a castor oil-modified bifunctional polyol, a castor oil-modified trifunctional polyol, a tetrafunctional polyol having a bisphenol A skeleton, a diluent, and an emulsifier. The diluent comprises alkyl sulfonic acid phenyl ester and dioctyl phthalate. In particular, the alkylsulfonic acid phenyl ester is preferably 5 to 15 parts by weight per 100 parts by weight of the water-dispersed polyol. By blending the alkylsulfonic acid phenyl ester, the composition is applied to the concrete base surface to a thickness of 3 to 5 mm. When applied, uniform resin float can be expressed on the surface of the coating material, and the coating workability can be improved. A commercially available alkylsulfonic acid phenyl ester is mezamol (trade name, manufactured by Bayer).
また、希釈剤に含まれるフタル酸ジオクチルは、水分散ポリオール１００重量部中２０〜４０重量部が好ましく、該フタル酸ジオクチルを配合することにより、本組成物をコンクリート下地表面に３〜５ｍｍ厚さに塗付する際の塗付作業性が良好なものとなる。 Further, the dioctyl phthalate contained in the diluent is preferably 20 to 40 parts by weight in 100 parts by weight of the water-dispersed polyol, and by blending the dioctyl phthalate, the composition is formed on the concrete base surface to a thickness of 3 to 5 mm. The coating workability at the time of applying to the coating becomes good.
水分散ポリオール中に配合されるひまし油変性３官能ポリオール、ビスフェノールＡ骨格を有する４官能ポリオールの水酸基当量は２５０〜４５０が好ましく、水酸基当量が２５０未満では水硬性ポリマーセメント組成物としての硬化が早くなって作業性が不良となり、水酸基当量が４５０超では水硬性ポリマーセメント組成物として硬化後の強度が不十分となる。 The hydroxyl equivalent of castor oil-modified trifunctional polyol and tetrafunctional polyol having a bisphenol A skeleton blended in the water-dispersed polyol is preferably 250 to 450, and when the hydroxyl equivalent is less than 250, curing as a hydraulic polymer cement composition is accelerated. Thus, workability becomes poor, and when the hydroxyl equivalent is more than 450, the strength after curing becomes insufficient as a hydraulic polymer cement composition.
また、水分散ポリオール中に配合されるヒマシ油変性２官能ポリオールの水酸基当量は、水分散ポリオールの水酸基当量が２５０〜４５０と成るように、他に配合される上記希釈剤、水、乳化剤の配合量によって調整する。 In addition, the hydroxyl equivalent of the castor oil-modified bifunctional polyol blended in the water-dispersed polyol is blended with the above diluent, water, and emulsifier blended so that the hydroxyl equivalent of the water-dispersed polyol is 250 to 450. Adjust according to the amount.
水分散ポリオールに使用する乳化剤としては、合成界面活性剤、樹脂酸塩系界面活性剤、タンパク系界面活性剤のいずれも使用でき、界面活性剤の種類としては、アニオン性界面活性剤、カチオン性界面活性剤、ノニオン性界面活性剤、両性界面活性剤が単独又は併用して使用することが出来る。乳化剤は本組成物の塗付作業性が下記評価方法によって良好になるよう、また硬化後の塗材の圧縮強度が十分となるようにこれらの活性剤の中から選択する。敢えてより好ましい乳化剤としては、アルキルベンゼンスルホン酸塩系を挙げることが出来る。 As the emulsifier used in the water-dispersed polyol, any of synthetic surfactants, resinate surfactants, and protein surfactants can be used. The types of surfactants are anionic surfactants and cationic surfactants. Surfactants, nonionic surfactants, and amphoteric surfactants can be used alone or in combination. The emulsifier is selected from these active agents so that the application workability of the composition is improved by the following evaluation method and the compressive strength of the coating material after curing is sufficient. As a more preferable emulsifier, an alkylbenzene sulfonate system can be mentioned.
本発明の水硬性ポリマーセメント組成物に使用するポリイソシアネートは、作業性が良好となり、また低温での速硬化性さらには硬化後の強度が高いことより、４，４´−ジフェニルメタンジイソシアネートからなるポリメリックＭＤＩ（ポリメチルポリフェニルポリイソシアネート）を使用することが好ましく、ＮＣＯ当量は１００〜１５０が好ましい。ＮＣＯ当量が１００未満では硬化物が発泡による膨れが生じる等で仕上がりが不良となり、ＮＣＯ当量が１５０超では硬化後の強度が不十分となる。もちろん、他の脂肪族ポリイソシアネートや芳香族ポリイソシアネートや脂環式ポリイソシアネート等も使用することもでき、また併用することも可能である。市販のポリメリックＭＤＩとしては、ルプラネートＭ５Ｓ（商品名、ＮＣＯ当量１３５、ＢＡＳＦ ＩＮＯＡＣポリウレタン社製）がある。 The polyisocyanate used in the hydraulic polymer cement composition of the present invention has good workability, is fast-curing at low temperature, and has high strength after curing, so that a polymer composed of 4,4′-diphenylmethane diisocyanate is used. MDI (polymethyl polyphenyl polyisocyanate) is preferably used, and the NCO equivalent is preferably 100 to 150. If the NCO equivalent is less than 100, the cured product will be swollen due to foaming or the like, and the finish will be poor. If the NCO equivalent exceeds 150, the strength after curing will be insufficient. Of course, other aliphatic polyisocyanates, aromatic polyisocyanates, alicyclic polyisocyanates and the like can also be used, and can also be used in combination. As a commercially available polymeric MDI, there is Lupranate M5S (trade name, NCO equivalent 135, manufactured by BASF INOAC Polyurethane).
水分散ポリオールの水酸基当量をポリイソシアネートのＮＣＯ当量で除した値は２〜３が好ましく、該値が２未満及び３超では、本組成物の色調が硬化後に徐々に白茶けてしまう場合がある。 The value obtained by dividing the hydroxyl group equivalent of the water-dispersed polyol by the NCO equivalent of the polyisocyanate is preferably 2 to 3, and if the value is less than 2 or more than 3, the color tone of the composition may gradually fade after curing. .
本発明の水硬性ポリマーセメント組成物に使用するベンズイミダゾール系化合物から成る防かび剤は、熱に対する安定性とｐＨに対する安定性が高いため、熱水洗浄が行われ、組成物としてセメントを含有する本水硬性ポリマーセメント組成物に適する防かび剤として使用される。市販品として１０％水懸濁液としてコートサイドＤ２（商品名、日本エンバイロケミカルズ株式会社製）がある。ベンズイミダゾール系化合物から成る防かび剤の配合量は、組成物全体１００重量部に対して０．１〜０．３重量部が好ましい。０．１重量部未満では防かび効果が不十分であり、０．３重量部超では貯蔵安定性が低下すると共にコスト高と成る。 The fungicide comprising a benzimidazole compound used in the hydraulic polymer cement composition of the present invention has high heat stability and high pH stability, and thus is washed with hot water and contains cement as a composition. Used as a fungicide suitable for the present hydraulic polymer cement composition. As a commercial product, there is Coatside D2 (trade name, manufactured by Nippon Enviro Chemicals Co., Ltd.) as a 10% aqueous suspension. As for the compounding quantity of the antifungal agent which consists of a benzimidazole type compound, 0.1-0.3 weight part is preferable with respect to 100 weight part of the whole composition. If the amount is less than 0.1 parts by weight, the fungicidal effect is insufficient, and if it exceeds 0.3 parts by weight, the storage stability is lowered and the cost is increased.
本発明の水硬性ポリマーセメント組成物に使用するセメントは、本発明の水系ポリウレタン組成物が床下地コンクリートに塗布し美観を付与することを目的としているため、特定の色調が付与できるように、主として白色ポルトランドセメントを使用することが好ましい。他に普通ポルトランドセメント、アルミナセメント、高炉セメント、早強ポルトランドセメントを併用することができる。セメントの配合量は組成物全体１００重量部中の１０〜１５重量部である。 The cement used in the hydraulic polymer cement composition of the present invention is intended to give the aesthetic appearance by applying the water-based polyurethane composition of the present invention to the floor foundation concrete, so that a specific color tone can be imparted mainly. It is preferred to use white Portland cement. In addition, ordinary Portland cement, alumina cement, blast furnace cement, and early-strength Portland cement can be used in combination. The blending amount of cement is 10 to 15 parts by weight in 100 parts by weight of the whole composition.
本発明の水硬性ポリマーセメント組成物に使用する骨材には、粒子径が０．５〜１．５ｍｍのガイシ粉末と、粒子径が０．２１〜１．１８ｍｍの硅砂と、粒子径が０．０７〜０．６ｍｍの硅砂を併用して使用する。ガイシ粉末は、ガイシの生産工場において破損若しくは廃棄されたガイシを粉砕処理したもので、陶磁器の持つ強度、耐摩耗性、耐熱性などを床に付与する効果がある。粒子径が０．５ｍｍ未満では床下地コンクリートへの塗布作業性が悪くなり、１．５ｍｍ超では組成物中への分散性及び硬化後の塗膜表面の凹凸が大きくなりすぎる。 The aggregate used in the hydraulic polymer cement composition of the present invention includes an insulator powder having a particle size of 0.5 to 1.5 mm, cinnabar sand having a particle size of 0.21 to 1.18 mm, and a particle size of 0. Use in combination with 0.07-0.6mm cinnabar sand. The insulator powder is obtained by pulverizing an insulator that has been damaged or discarded at an insulator factory, and has the effect of imparting the strength, wear resistance, heat resistance, etc. of ceramics to the floor. When the particle diameter is less than 0.5 mm, the workability of application to the floor foundation concrete is deteriorated, and when it exceeds 1.5 mm, the dispersibility in the composition and the unevenness of the coating surface after curing become too large.
粒子径が０．２１〜１．１８ｍｍの硅砂は硅砂４号が、粒子径が０．０７〜０．６ｍｍの硅砂は６号硅砂がそれぞれ該当する。粒子径が０．５〜１．５ｍｍのガイシ粉末と、粒子径が０．２１〜１．１８ｍｍの硅砂と、粒子径が０．０７〜０．６ｍｍの硅砂の併用比率は、重量で０．９〜１．１：３．０〜４．０：０．５〜０．７が床下地コンクリートへの塗布作業性と強度発現及び耐衝撃性の観点から好ましい。ガイシ粉末及びこれらの硅砂の合計量が組成物全体に対する割合は、組成物全体１００重量部中７５〜９０重量部である。７５重量部未満では硬化物表面に樹脂が浮いて防滑性が低下し、９０重量部超では塗布作業性が不良となる。 The cinnabar No. 4 corresponds to the cinnabar having a particle diameter of 0.21-1.18 mm, and the cinnabar No. 6 corresponds to the cinnabar having a particle diameter of 0.07-0.6 mm. The combined ratio of the insulator powder having a particle diameter of 0.5 to 1.5 mm, the cinnabar having a particle diameter of 0.21 to 1.18 mm, and the cinnabar having a particle diameter of 0.07 to 0.6 mm is 0. 9-1.1: 3.0-4.0: 0.5-0.7 are preferable from the viewpoint of application workability to floor foundation concrete, strength development and impact resistance. The ratio of the total amount of potato powder and these cinnabar to the whole composition is 75 to 90 parts by weight in 100 parts by weight of the whole composition. If it is less than 75 parts by weight, the resin floats on the surface of the cured product and the slip resistance is lowered, and if it exceeds 90 parts by weight, the coating workability becomes poor.
本発明の水硬性ポリマーセメント組成物には、上記のほかに消石灰を配合することが好ましい。該消石灰は、ポリイソシアネートと水とのウレア反応で発生する炭酸ガスを吸収し、組成物が床下地コンクリート上に塗布され硬化するまでに発生する炭酸ガスが特定部分に集中して塗膜を押上げて膨れを生じさせることを抑制する効果がある。 In addition to the above, slaked lime is preferably added to the hydraulic polymer cement composition of the present invention. The slaked lime absorbs carbon dioxide gas generated by the urea reaction between polyisocyanate and water, and the carbon dioxide gas generated until the composition is applied on the floor foundation concrete and hardens to concentrate on a specific part to press the coating film. This has the effect of suppressing the occurrence of swelling.
