Abstract
Description
本発明は、コンクリートやモルタル等のような表面の粗い無機材料からなる建材の表面を保護する建材用コーティング膜及び建材用コーティング剤に関する。 The present invention relates to a building material coating film and a building material coating agent that protect the surface of a building material made of an inorganic material having a rough surface such as concrete or mortar.
建設現場等において、コンクリートやモルタル等の無機材料からなる建材を施工して、飛散した当該材料の粉末が、施工した当該建材の表面に付着してそのまま乾燥してしまうと、付着した当該材料の粉末を施工した当該建材から除去するのに非常に手間がかかってしまう。このため、従来、建設現場等においては、粘着層を設けた和紙やポリ塩化ビニルシートやポリエチレンシート等を、施工後の当該建材の表面に被覆し、不要となった時点で当該建材の表面から当該シート等を手で引き剥がすようにしている。 When construction materials made of inorganic materials such as concrete and mortar are constructed at construction sites, etc., the scattered powder of the material adheres to the surface of the constructed building material and is dried as it is. It takes a lot of work to remove the powder from the construction material. For this reason, conventionally, at construction sites, etc., the surface of the building material after construction is covered with Japanese paper, a polyvinyl chloride sheet, a polyethylene sheet, or the like provided with an adhesive layer. The sheet or the like is peeled off by hand.
しかしながら、施工した前記建材の表面を和紙で被覆した場合には、和紙の強度が弱いため、前記建材の表面から引き剥がす際に、当該和紙がすぐに切れてしまい、除去作業に手間がかかってしまっていた。他方、施工した前記建材の表面を前述したような樹脂シートで被覆した場合には、雨等の天候の影響によって、被覆した当該シートに部分的又は全面的に浮きや剥がれ等を生じてしまい、当該建材の表面が汚れてしまうことがあった。 However, when the surface of the building material that has been applied is covered with Japanese paper, the strength of the Japanese paper is weak, so when it is peeled off from the surface of the building material, the Japanese paper is immediately cut, which takes time and effort to remove. I was sorry. On the other hand, when the surface of the building material that has been constructed is covered with the resin sheet as described above, due to the influence of the weather such as rain, the covered sheet may partially or completely float or peel off, The surface of the building material sometimes gets dirty.
このため、手による剥離作業が容易でありながらも、建材の表面を長期にわたって確実に保護できるようにすることが強く望まれていた。 For this reason, it has been strongly desired that the surface of the building material can be reliably protected over a long period of time while being easily peeled off by hand.

At the same time, it can be peeled off from the surface of the building material made of an inorganic material having a rough surface such as concrete or mortar without being cut off in the middle, and the removal operation can be performed very easily.
ここで、上記建材用コーティング膜は、上記ウレタン樹脂が脂肪族系（例えば、イソホロンジイソシアネート（ＩＰＤＩ）、ヘキサメチレンジイソシアネート（ＨＤＩ）、水添ジフェニルメタンジイソシアネート等のようなジイソイアネート類や、イソシアヌレート結合ＨＤＩ等のような特殊ポリイソシアネート類等）であると、変色しにくく、非常に好ましい。 Here, the coating film for building materials is such that the urethane resin is aliphatic (for example, diisocyanates such as isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI), hydrogenated diphenylmethane diisocyanate, isocyanurate-bonded HDI, etc. And special polyisocyanates) are very preferable because they are less likely to discolor.
そして、本実施形態に係る建材用コーティング剤は、ウレタン樹脂を水に分散又は溶解させたものであり、造膜したときの前記ウレタン樹脂が、２００〜９００％（好ましくは３００〜７００％）の破断伸びを有すると共に、２００〜８００ｋｇ／ｃｍ2（好ましくは２５０〜５００ｋｇ／ｃｍ2）の引張強度を有するものである。 And the coating agent for building materials which concerns on this embodiment is what disperse | distributed or melt | dissolved urethane resin in water, and the said urethane resin when it forms into a film is 200 to 900% (preferably 300 to 700%). While having elongation at break, it has a tensile strength of 200 to 800 kg / cm 2 (preferably 250 to 500 kg / cm 2 ).
この本実施形態に係る建材用コーティング剤においては、必要に応じて、上述した可塑剤や紫外線吸収剤や剥離向上剤等はもちろんのこと、消泡剤（例えば、鉱油類、シリコーン類等）、増粘剤（例えば、無機系、有機系等）、ｐＨ 調整剤（例えば、有機アルカリ類、エタノールアミン類等）、防腐剤（例えば、ベンゾイソチアゾリン類、トリアジン類等）、造膜助剤（例えば、プロピレングリコールアルキルエーテル類等）、凍結防止剤（多価アルコール類等）、乾燥促進剤（エタノール等の低級アルコール類等）等の添加剤を含有することも可能である。 In the coating agent for building materials according to this embodiment, if necessary, not only the above-mentioned plasticizer, ultraviolet absorber, peeling improver, etc., but also an antifoaming agent (for example, mineral oils, silicones, etc.), Thickeners (eg, inorganic and organic), pH adjusters (eg, organic alkalis, ethanolamines, etc.), preservatives (eg, benzoisothiazolines, triazines, etc.), film-forming aids (eg, , Propylene glycol alkyl ethers, etc.), antifreezing agents (polyhydric alcohols, etc.), drying accelerators (lower alcohols such as ethanol, etc.) and the like can also be contained.

However, the above-mentioned coating film for building materials can be easily constructed, the construction work can be speeded up, and since water is used as a solvent, the hygienic and safety of the work environment is ensured. Can be easily done
ここで、上記建材用コーティング剤は、上記ウレタン樹脂が脂肪族系（例えば、イソホロンジイソシアネート（ＩＰＤＩ）、ヘキサメチレンジイソシアネート（ＨＤＩ）、水添ジフェニルメタンジイソシアネート等のようなジイソイアネート類や、イソシアヌレート結合ＨＤＩ等のような特殊ポリイソシアネート類等）であると、当該ウレタン樹脂が造膜した後に変色することがないので、非常に好ましい。 Here, the building material coating agent is such that the urethane resin is aliphatic (for example, diisocyanates such as isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI), hydrogenated diphenylmethane diisocyanate, isocyanurate-bonded HDI, etc. And the like, such as special polyisocyanates) is very preferable because the urethane resin does not change color after film formation.
さらに、上記建材用コーティング剤は、前記ウレタン樹脂が、上記親水性基（例えば、スルホン酸基、カルボン酸基、水酸基、硫酸エステル基、リン酸基、アンモニウム基、シアン基、チオ基、酸化エチレン基等）又は親水性セグメントを有している、すなわち、自己乳化型であると、例えば、界面活性剤を添加して水に分散させた強制乳化型で生じるような問題（造膜して乾燥したときに塗膜中に界面活性剤が残存して、降雨にあった場合に膜が相溶しやすく、十分な耐水性を発揮することができない）がないため、非常に好ましい。 Furthermore, in the building material coating agent, the urethane resin contains the hydrophilic group (for example, sulfonic acid group, carboxylic acid group, hydroxyl group, sulfate ester group, phosphoric acid group, ammonium group, cyan group, thio group, ethylene oxide). Group) or a hydrophilic segment, that is, a self-emulsifying type, for example, a problem that occurs in a forced emulsifying type in which a surfactant is added and dispersed in water (film formation and drying) In this case, the surface active agent remains in the coating film, and when it is raining, the film is easily compatible and cannot exhibit sufficient water resistance.
また、上記建材用コーティング剤は、前記ウレタン樹脂が、５℃以下の最低造膜温度（ＭＦＴ）を有していると、一般的な施工現場であれば造膜を確実に行うことができるので、非常に好ましい。 Moreover, since the said urethane resin has the minimum film-forming temperature (MFT) of 5 degrees C or less, since the said coating material for building materials can perform film-forming reliably at a general construction site, Very preferred.
加えて、上記建材用コーティング剤は、前記ウレタン樹脂が、一液タイプであると、二液タイプのように二種類の溶液を混合する必要がなく、そのまま塗布して造膜させることができるので、施工作業の迅速化をさらに図ることができ、非常に好ましい。 In addition, if the urethane resin is a one-component type, it is not necessary to mix two types of solutions as in the two-component type, and the coating agent for building materials can be applied as it is to form a film. The construction work can be further speeded up, which is very preferable.
