Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a polyurethane based cement composition is usually used after mixing an organic isocyanate compound and a cement based aggregate to a water-dispersed emulsion of a polyol at an application job site, but because an alkaline aggregate is used, the reaction of isocyanate is promoted and a usable time after mixing is short and also the reaction of water and the isocyanate occurs rapidly and a coating film foams by a generated carbon dioxide gas and finish failure could be caused and especially it becomes worse when a polymeric MDI from which a formulation having high physical properties can be obtained is used. <P>SOLUTION: In the polyurethane based cement composition containing the polyol, the water, the isocyanate and a hydraulic cement as components, an aqueous urethane mortar composition contains a triaryl ester of phosphoric acid. <P>COPYRIGHT: (C)2009,JPO&INPIT

Concerning improvement of usable time and foaming resistance.

従来、厨房室、試験室、薬品・化学工場、電子回路の工場などの床には防水性、耐熱性、耐薬品性、耐熱水性並びに耐衝撃強度などの機能を付加させるため、打設したコンクリート表面に強化樹脂を施工した複合床や、ウレタン樹脂、エポキシ樹脂などの熱硬化性樹脂とセメントとを配合した樹脂モルタル系の床が施工されている。   Conventionally, concrete that has been cast in order to add functions such as waterproofness, heat resistance, chemical resistance, hot water resistance, and impact strength to floors in kitchen rooms, test rooms, chemical and chemical factories, electronic circuit factories, etc. Composite floors with reinforced resin on the surface and resin mortar floors with cement and thermosetting resins such as urethane resin and epoxy resin are being constructed.

特に、水硬性セメント、水、ポリオールおよびイソシアネート化合物からなるポリウレタン系セメント組成物は、熱や機械的な衝撃強度に優れるため、大きな負荷のかかる部位の床に施工される。   In particular, a polyurethane cement composition composed of hydraulic cement, water, a polyol, and an isocyanate compound is excellent in heat and mechanical impact strength, and is therefore applied to a floor at a site where a large load is applied.

水硬性セメント（ａ）、骨材（ｂ）、活性水素化合物（ｃ）、イソシアネート化合物（ｄ）、アルキルベンゼンスルホン酸塩（ｅ）および水（ｆ）を含有してなり、（ｅ）の配合量が（ｃ）に対して０．１〜２．０重量％であり、全組成物に対して０．００１〜０．２０重量％である水性レジンモルタル組成物が開示され、可塑剤として、リン酸エステルを記載しているが、本願の効果を見出していない。（特許文献３）   A hydraulic cement (a), an aggregate (b), an active hydrogen compound (c), an isocyanate compound (d), an alkylbenzene sulfonate (e) and water (f) are contained, and the blending amount of (e) An aqueous resin mortar composition is disclosed in which 0.1 to 2.0% by weight with respect to (c) and 0.001 to 0.20% by weight with respect to the total composition. Although an acid ester is described, the effect of the present application has not been found. (Patent Document 3)

（ａ）活性水素含有化合物及び（ｃ）セメント減水剤を、水に添加し、混合することからなる分散液、及び、該分散液に、有機ポリイソシアネート及び水硬性セメントを混合し、基材に塗布し、硬化させることを特徴とするセメント組成物の硬化方法で施工性、作業性の改善が開示されている。(特許文献４)   (A) An active hydrogen-containing compound and (c) a cement water reducing agent are added to water and mixed, and the dispersion is mixed with organic polyisocyanate and hydraulic cement to form a base material. An improvement in workability and workability is disclosed in a method for curing a cement composition characterized by applying and curing. (Patent Document 4)

しかし、これらウレタンモルタル組成物は水硬性セメントと水を含むことにより、イソシアネート化合物と反応が進み、混合後の使用可能時間が短く、発泡による仕上がり不良が起こる。また、添加剤、組成物配合で、改良はされるものの解消には至らないものであった。特に、ポリメリックＭＤＩを用いる場合は、強度・硬化性・耐熱性は他のイソシアネート化合物に比べ優れるものの、可使時間が短く、発泡することが多かった。

(Patent Document 5)
However, these urethane mortar compositions contain a hydraulic cement and water, so that the reaction with the isocyanate compound proceeds, the usable time after mixing is short, and a poor finish due to foaming occurs. In addition, additives and compositions were improved, but not improved. In particular, when polymeric MDI is used, the strength, curability and heat resistance are superior to other isocyanate compounds, but the pot life is short and foaming often occurs.
JP 2000-72507 A JP-A-2005-47719 JP 2002-179454 A Japanese Patent Laid-Open No. 08-169740 JP 2004-67463 A

ポリウレタン系セメント組成物は、通常ポリオールの水分散エマルジョンに、有機イソシアネート化合物、セメント系骨材を施工現場にて混合し使用するが、アルカリ性の骨材を使用するために、イソシアネートの反応が促進され、混合後の使用可能時間が短いことや、水とイソシアネートとの反応が急激に起こり、発生した炭酸ガスにより塗膜が発泡して仕上がり不良となることがあるという問題がある。
これは、混合物中の反応として、疎水相内でのイソシアネートとポリオールの反応にくらべて、疎水相と親水相界面でのイソシアネートと水の反応が充分に遅くないために起こる不具合であると考えられる。 Polyurethane-based cement compositions are usually used by mixing an organic isocyanate compound and cement-based aggregate in a water-dispersed emulsion of polyol at the construction site. However, since alkaline aggregate is used, the reaction of isocyanate is accelerated. There are problems that the usable time after mixing is short, and that the reaction between water and isocyanate occurs rapidly, and the coating film is foamed by the generated carbon dioxide gas, resulting in poor finishing.
This is considered to be a malfunction that occurs because the reaction between the isocyanate and water at the interface between the hydrophobic phase and the hydrophilic phase is not sufficiently slow as the reaction in the mixture, compared to the reaction between the isocyanate and polyol in the hydrophobic phase. .

ポリウレタン系セメント組成物において、使用可能時間を延長し、発泡による仕上り不良を無くする。   In the polyurethane-based cement composition, the usable time is extended, and the finishing failure due to foaming is eliminated.

請求項1の発明はポリオール、水、イソシアネート、水硬性セメントを成分とするポリウレタン系セメント組成物においてリン酸トリアリールエステルを含むことを特徴とする水性ウレタンモルタル組成物で使用可能時間を延ばし、発泡による仕上がり不良を生じさせない。
請求項２の発明はイソシアネートが多核ポリフェニレンポリメチルポリイソシアネートである請求項1記載の水性ウレタンモルタル組成物で、優れた強度・硬化性・耐熱性を有する組成物で使用可能時間を延ばし、発泡による仕上がり不良を生じさせない。
請求項３の発明は請求項1乃至２いずれか記載の水性ウレタンモルタル組成物からなる床で、可使時間が、長く、作業性が優れ、発泡による外観不良がない、強度・硬化性・耐熱性に優れた塗床材となる。 The invention according to claim 1 is a polyurethane-based cement composition comprising polyol, water, isocyanate, and hydraulic cement as a component. Does not cause poor finish due to.
The invention according to claim 2 is the aqueous urethane mortar composition according to claim 1, wherein the isocyanate is a polynuclear polyphenylene polymethyl polyisocyanate. The composition has excellent strength, curability and heat resistance, extends the usable time, and is foamed. Does not cause poor finish.
The invention of claim 3 is a floor comprising the water-based urethane mortar composition according to any one of claims 1 to 2, has a long pot life, excellent workability, no appearance defect due to foaming, strength, curability and heat resistance. It becomes a coating material with excellent properties.

リン酸トリアリールエステルを添加することで使用可能時間が延長され、発泡による仕上り不良が生じ難くなり、施工に起因する欠損が少なく良好な塗膜を得られる。   By adding phosphoric acid triaryl ester, the usable time is extended, the finishing failure due to foaming is less likely to occur, and a good coating film with few defects due to construction can be obtained.

本発明はポリオール、水、イソシアネート、水硬性セメントを成分とするポリウレタン系セメント組成物にリン酸トリアリールエステルを含むことで使用可能時間が延長され、発泡による仕上り不良が生じ難くなることを鋭意検討の結果発明できた。
これは、リン酸トリアリールエステルが親水相と疎水相の界面を保護し、水とイソシアネート化合物の接触が困難になるためと考えられる。 In the present invention, a polyurethane cement composition containing polyol, water, isocyanate, and hydraulic cement as a component contains a triaryl phosphate, so that the usable time is extended and poor finishing due to foaming is less likely to occur. As a result, it was invented.
This is presumably because the triaryl phosphate ester protects the interface between the hydrophilic phase and the hydrophobic phase, making it difficult to contact water with the isocyanate compound.

リン酸トリアリールエステルは、リン酸トリクレジル、リン酸クレジルジフェニル等のリン酸の活性水素が３つともフェノール誘導体と縮合した構造をもつトリエステルが使用できる。これらは水に不溶な性質を有する。   As the triaryl phosphate, a triester having a structure in which all three active hydrogens of phosphoric acid such as tricresyl phosphate and cresyl diphenyl phosphate are condensed with a phenol derivative can be used. These have water-insoluble properties.
