Abstract
Description
本発明は、新規な被覆材に関するものである。 The present invention relates to a novel coating material.
近年、商業施設、集合住宅、戸建住宅等の建築物においては、高断熱化・高気密化によって、冷暖房費の節約を図り、省資源化を実現しようとする動きが盛んである。一般に、断熱設計を施していない建築物では、冬期の暖房時には屋根、床、窓、壁等の部位から屋内の熱が逃げ、夏期の冷房時にはこれら部位から屋外の熱が侵入してしまう。 In recent years, in buildings such as commercial facilities, apartment houses, and detached houses, there have been active efforts to save resources by conserving air conditioning costs by increasing heat insulation and airtightness. In general, in a building that is not designed for thermal insulation, indoor heat escapes from the roof, floor, window, wall, and the like during heating in the winter, and outdoor heat enters through these parts during cooling in the summer.
このような熱損失を抑制し、建築物の省資源化を実現するには、屋内と屋外を隔てる上記各種部位の高断熱化が不可欠である。このような要望に対し、断熱性材料を設けた構造が種々提案されている。一例として、建築物の屋外側表面に、ポリスチレンフォームやフェノールフォーム等による断熱材を設置し、さらにその上に被覆材を設けた構造が知られている（例えば特許文献１等）。 In order to suppress such heat loss and realize resource saving of buildings, it is indispensable to increase the heat insulation of the various parts that separate the indoor and the outdoor. In response to such a demand, various structures provided with a heat insulating material have been proposed. As an example, a structure in which a heat insulating material such as polystyrene foam or phenol foam is installed on the outdoor surface of a building and a covering material is further provided thereon (for example, Patent Document 1) is known.
しかしながら、このような積層構造で用いられる断熱材は、高温に晒されると変形、燃焼等が生じやすく、耐熱性は不十分である。自己消火性等が付与された断熱材を採用すれば、耐熱性の向上が期待されるが、条件によっては十分な耐熱性向上効果が得られ難い場合がある。 However, the heat insulating material used in such a laminated structure is likely to be deformed and burned when exposed to a high temperature and has insufficient heat resistance. If a heat insulating material provided with self-extinguishing properties and the like is adopted, an improvement in heat resistance is expected, but depending on conditions, it may be difficult to obtain a sufficient heat resistance improvement effect.
本発明は、上述のような問題点に鑑みなされたもので、建築物において、その耐熱性を高めることのできる被覆材を得ることを目的とするものである。 This invention is made | formed in view of the above problems, and it aims at obtaining the coating | covering material which can improve the heat resistance in a building.
本発明者は、上記目的を達成するため鋭意検討を行った結果、特定の被膜層を１種または２種以上積層することによって形成される被覆材に想到し、本発明を完成させるに到った。 As a result of intensive studies to achieve the above object, the present inventors have conceived a coating material formed by laminating one or more specific coating layers, and have completed the present invention.

以下、本発明を実施するための形態について説明する。 Hereinafter, modes for carrying out the present invention will be described.
本発明の被覆材は、１種または２種以上の被膜層を積層することによって形成されたものである。被覆材を形成する各被膜層は、結合材として樹脂成分を含有する。 The coating material of this invention is formed by laminating | stacking 1 type, or 2 or more types of film layers. Each coating layer forming the coating material contains a resin component as a binder.
本発明において、被覆材を形成する被膜層の少なくとも１種以上は、樹脂成分、及び吸熱物質を含有するものである。本発明では、このような被膜層を使用することによって、耐熱性を高めることができる。 In the present invention, at least one of the coating layers forming the coating material contains a resin component and an endothermic substance. In this invention, heat resistance can be improved by using such a coating layer.
吸熱物質は、加熱により水を放出する金属化合物である。このような吸熱物質は、加熱の際、水蒸気を発生し、その吸熱作用によって耐熱性向上に寄与するものである。
このような吸熱物質としては、例えば、水酸化アルミニウム、水酸化マグネシウム、水酸化カルシウム、水酸化バリウム、水酸化ストロンチウム、水酸化スカンジウム等の金属水酸化物；ホウ砂（四ホウ酸ナトリウム）、八ホウ酸二ナトリウム、ホウ酸亜鉛等の金属ホウ酸塩；ゼオライト、ハロイサイト、アロフェン、エトリンジャイト等が挙げられ、これらの１種または２種以上が使用できる。吸熱物質としては、特に金属水酸化物が好適である。
The endothermic substance is a metal compound that releases water when heated. Such an endothermic substance generates water vapor during heating and contributes to the improvement of heat resistance by its endothermic action.
Examples of such endothermic substances include metal hydroxides such as aluminum hydroxide, magnesium hydroxide, calcium hydroxide, barium hydroxide, strontium hydroxide, scandium hydroxide; borax (sodium tetraborate), eight Metal borate such as disodium borate and zinc borate; zeolite, halloysite, allophane, ettringite and the like can be mentioned, and one or more of these can be used. As the endothermic substance, a metal hydroxide is particularly suitable.
吸熱物質の比率は、樹脂成分の固形分１００重量部に対し、好ましくは１０〜８００重量部、より好ましくは２０〜６００重量部、さらに好ましくは４０〜５００重量部、最も好ましくは６０〜４００重量部である。吸熱物質がこのような比率であれば、十分な耐熱性向上効果が得られる。 The ratio of the endothermic substance is preferably 10 to 800 parts by weight, more preferably 20 to 600 parts by weight, still more preferably 40 to 500 parts by weight, and most preferably 60 to 400 parts by weight with respect to 100 parts by weight of the solid content of the resin component. Part. When the endothermic substance has such a ratio, a sufficient heat resistance improvement effect can be obtained.
被膜層の樹脂成分としては、例えば、酢酸ビニル樹脂、ポリエステル樹脂、アルキッド樹脂、塩化ビニル樹脂、エポキシ樹脂、アクリル樹脂、ウレタン樹脂、アクリルシリコン樹脂、フッ素樹脂等が使用可能である。これらは１種または２種以上で使用することができる。また、これら樹脂成分は架橋反応性を有するものであってもよい。 As the resin component of the coating layer, for example, vinyl acetate resin, polyester resin, alkyd resin, vinyl chloride resin, epoxy resin, acrylic resin, urethane resin, acrylic silicon resin, fluorine resin, and the like can be used. These can be used alone or in combination of two or more. Moreover, these resin components may have a crosslinking reactivity.
本発明では、被覆材を形成する被膜層の少なくとも１種以上が、樹脂成分として、有機樹脂及びシリコン物質を含むことが望ましい。有機樹脂及びシリコン物質を含む樹脂成分（以下、単に「複合樹脂」とも言う。）を含有する被膜層を使用すれば、本発明の効果を一層高めることが可能となる。このような複合樹脂の形態としては、有機樹脂とシリコン物質を混合した形態、有機樹脂とシリコン物質を反応させた形態等が挙げられる。有機樹脂とシリコン物質の重量比率は、固形分換算で１００：１０〜１００：９０であることが好ましく、より好ましくは１００：１５〜１００：７０である。この範囲を満たす場合、一層耐熱性に優れた被膜層を形成することができる。特にこのような被覆材は断熱材等の表面被覆に採用した場合に効果的である。この作用機構は明らかではないが、上記複合樹脂を用いた被膜層は耐熱性に加え通気性を有するため、断熱層に上記の被覆材を積層した積層構造体が高温に晒された場合には、断熱層より発生した可燃性ガスが、積層構造体の内部または表層に滞留し難くなり、燃焼を効果的に抑制することができると推測される。 In the present invention, it is desirable that at least one of the coating layers forming the coating material includes an organic resin and a silicon substance as a resin component. If a coating layer containing a resin component containing an organic resin and a silicon substance (hereinafter also simply referred to as “composite resin”) is used, the effects of the present invention can be further enhanced. Examples of such a composite resin include a form in which an organic resin and a silicon substance are mixed, a form in which an organic resin and a silicon substance are reacted, and the like. The weight ratio of the organic resin to the silicon substance is preferably 100: 10 to 100: 90, more preferably 100: 15 to 100: 70 in terms of solid content. When satisfy | filling this range, the film layer which was further excellent in heat resistance can be formed. In particular, such a coating material is effective when it is used for a surface coating such as a heat insulating material. Although the mechanism of this action is not clear, since the coating layer using the composite resin has air permeability in addition to heat resistance, when the laminated structure in which the coating material is laminated on the heat insulating layer is exposed to high temperature It is presumed that the combustible gas generated from the heat insulating layer hardly stays in the laminated structure or in the surface layer and can effectively suppress the combustion.
上記複合樹脂のうち、有機樹脂としては上述の各種樹脂が挙げられ、この中でもアクリル樹脂が好適である。アクリル樹脂は、各種アクリルモノマーを重合、あるいは、各種アクリルモノマーとその他のモノマーを共重合することにより得ることができる。このうちアクリルモノマーとしては、例えば、メチル（メタ）アクリレート、エチル（メタ）アクリレート、イソプロピル（メタ）アクリレート、ｎ−ブチル（メタ）アクリレート、イソブチル（メタ）アクリレート、ｎ−ヘキシル（メタ）アクリレート、２−エチルヘキシル（メタ）アクリレート、シクロヘキシル（メタ）アクリレート、フェニル（メタ）アクリレート、ベンジル（メタ）アクリレート等の（メタ）アクリル酸アルキルエステル；（メタ）アクリル酸等のカルボキシル基含有アクリルモノマー；Ｎ−メチルアミノエチル（メタ）アクリレート等のアミノ基含有アクリルモノマー；（メタ）アクリルアミド等のアミド基含有アクリルモノマー；ダイアセトン（メタ）アクリルアミド等のカルボニル基含有アクリルモノマー；２−ヒドロキシエチル（メタ）アクリレート等の水酸基含有アクリルモノマー；（メタ）アクリルニトリル等のニトリル基含有アクリルモノマー；γ−（メタ）アクリロイルオキシプロピルトリメトキシシラン等の加水分解性シリル基含有アクリルモノマー等が挙げられる。 Among the above composite resins, examples of the organic resin include the various resins described above, and among these, acrylic resins are preferable. The acrylic resin can be obtained by polymerizing various acrylic monomers or copolymerizing various acrylic monomers and other monomers.

Among the composite resins, examples of the silicon substance include silica, silicone, and the like, and silica is particularly preferable.
Such silica can be produced using, for example, sodium silicate, lithium silicate, potassium silicate, or a silicate compound as a raw material. Among these, as silicate compounds, for example, tetramethoxysilane, tetraethoxysilane, tetra n-propoxysilane, tetraisopropoxysilane, tetra n-butoxysilane, tetraisobutoxysilane, tetrasec-butoxysilane, tetra-t-butoxy Examples thereof include silane, tetraphenoxysilane, and their condensates.

Further, after the production process or after production, the metal contained in the catalyst or the like can be removed by ion exchange treatment or the like. The particle diameter of silica is preferably 1 to 200 nm, more preferably 3 to 100 nm.
このような複合樹脂としては、特に、アクリル樹脂エマルション及びシリカを含むものが好適である。このうち、アクリル樹脂エマルションとしては、シリカと反応可能なものが好適である。具体的には、シリカに存在するシラノール基と反応可能な、水酸基、加水分解性シリル基等（好ましくは、加水分解性シリル基）の官能基を有するエマルションであることが好ましい。このような樹脂成分を用いることにより、本発明の効果をいっそう高めることができる。この作用機構は明らかではないが、上記複合樹脂を用いた被膜層では、シリカが凝集することなく、被膜層全体に分散して存在するため、耐熱性及び通気性に優れるとともに、有機樹脂の燃焼を抑制することができると推察される。 As such a composite resin, those containing an acrylic resin emulsion and silica are particularly suitable. Among these, as the acrylic resin emulsion, those capable of reacting with silica are preferable. Specifically, the emulsion is preferably an emulsion having a functional group such as a hydroxyl group or a hydrolyzable silyl group (preferably a hydrolyzable silyl group) capable of reacting with a silanol group present in silica. By using such a resin component, the effect of the present invention can be further enhanced. Although this mechanism of action is not clear, in the coating layer using the above composite resin, silica is not aggregated and is dispersed throughout the coating layer, so that it has excellent heat resistance and air permeability and combustion of organic resin. It is speculated that it can be suppressed.
