Description
この発明は、主に屋根材として用いられる粘土瓦、セメント瓦、スレート瓦等の種々の瓦に塗布され、この瓦に優れた非透水性その他の性能を付与することができる瓦用コーティング剤組成物に関する。 The present invention is applied to various tiles such as clay tiles, cement tiles, slate tiles and the like mainly used as roofing materials, and the coating composition for tiles that can impart excellent water permeability and other performances to the tiles Related to things.
瓦を屋根材として建築物の屋根を葺く場合、一般的には、垂木や母屋材に木製の野地板を固定し、必要により瓦固定部材を介して、この野地板に瓦を固定することにより施工される。 When roofing a building using tiles as a roofing material, generally, a wooden field board is fixed to the rafters and the main building, and if necessary, the tile is fixed to the field board through a tile fixing member. It is constructed by.
しかるに、素材として粘土を用い、これを所定の形状に成形した後、焼成して製造される燻し瓦や釉薬瓦等の粘土瓦や、セメントを原料として製造されるセメント瓦や、セメントに向き繊維を混ぜたものを原料として製造されるスレート瓦等は、それ自体では完全な非透水性を達成することが困難であり、長時間雨水に晒されると、たとえ釉薬瓦であってもじわじわと瓦本体中に雨水が浸透し、ひいては野地板や垂木、母屋材にまで達し、長年のうちにはこの野地板や垂木、母屋材が腐食してくるという問題がある。 However, clay is used as a raw material, molded into a predetermined shape and then fired to produce clay tiles such as glazed roof tiles and glaze roof tiles, cement tiles manufactured using cement as a raw material, and fibers suitable for cement. Slate roof tiles, etc. that are manufactured using a mixture of slags as such are difficult to achieve complete impermeability by themselves, and when exposed to rainwater for a long time, even if they are glaze roof tiles, There is a problem that rainwater permeates into the main body and eventually reaches the base plate, rafters and purlins, and the base plate, rafters and purlins corrode over the years.
そこで、従来においても、このような問題に対する幾つかの対策が提案されている。
例えば、塗料の研究No.135、第75〜79頁(Oct.2000)には、シリコン変性アクリルポリオール樹脂を用いたポリイソシアネート硬化タイプの弱溶剤系下塗り塗料や、同じくシリコン変性アクリルポリオール樹脂を用いたポリイソシアネート硬化タイプの弱溶剤系上塗り塗料を用いる、スレート瓦やセメント瓦に好適なシリコン防水コーティング工法が提案されている。
Therefore, some countermeasures for such a problem have been proposed in the past.
For example, paint research No. 135, pp. 75-79 (Oct. 2000) uses a polyisocyanate-curing weak solvent-based undercoat paint using a silicon-modified acrylic polyol resin, and also a silicon-modified acrylic polyol resin. A silicon waterproof coating method suitable for slate roofing and cement roofing using a polyisocyanate-curing weak solvent-based topcoat has been proposed.
また、特開平9-235,830号公報には、耐候性、耐薬品性、耐塩水性、耐熱性、撥水性、防汚性に優れた瓦として、焼成粘土瓦の表面にチタン酸カリウム繊維を含有する硬化型のシリコン系樹脂の被膜を1層又は2層設けた瓦及びその製造方法並びに施工方法が提案されている。 JP-A-9-235,830 discloses that the surface of the fired clay roof tile contains potassium titanate fibers as a roof tile excellent in weather resistance, chemical resistance, salt water resistance, heat resistance, water repellency, and antifouling properties. A roof tile provided with one or two layers of a curable silicone resin coating, a manufacturing method thereof, and a construction method have been proposed.
更に、特開平10-54,116号公報には、野地板それ自体を改良してこの野地板や垂木、母屋材等の腐食を防止するための手段として、耐食性を有する金属板よりなり、山部と谷部とがそれぞれ平行に複数形成されている野地板本体に、表面側では山部の頂部に水勾配方向及び水勾配方向に直行する方向にそれぞれ所定の間隔を隔てて固定用ボルトが溶接により突出固定されており、また裏面側では所定の位置に取付用ボルトが溶接により突出固定されている金属製野地板が提案されている。 Furthermore, in JP-A-10-54,116, as a means for improving the field plate itself and preventing corrosion of the field plate, rafters, purlins, etc., a metal plate having corrosion resistance is used. Fixing bolts are welded to the base plate main body formed with a plurality of valleys in parallel with each other at a predetermined interval in the water gradient direction and the direction perpendicular to the water gradient direction on the top side of the peak portion on the surface side. There has been proposed a metal base plate that is fixedly protruded and has a mounting bolt protruded and fixed at a predetermined position on the back surface side by welding.
更にまた、特開2004-108,006号公報には、不織布に松脂を含ませてなるシートであって、屋根瓦等の防水材と野地板等の下地材との間に介在させ、雨雪からの下地材の腐食防止と防水を目的として用いられる耐腐蝕性内葺きシートが提案されている。 Furthermore, JP-A-2004-108,006 discloses a sheet made of non-woven fabric containing pine resin, and is interposed between a waterproof material such as a roof tile and a base material such as a field board, and from rain and snow. Corrosion-resistant inner-sheets have been proposed that are used for the purpose of preventing corrosion and waterproofing of the base material.
しかしながら、これら従来の対策は、有機系の樹脂や溶剤を含む塗料を用いたり、高価な添加剤を用いたり、野地板それ自体を耐食性に優れた金属板で形成したり、更には、屋根瓦と野地板との間に別部材の耐腐蝕性内葺きシートを設ける等、環境衛生面や瓦葺施工面、更には経済性等において必ずしも十分であるとはいえない。 However, these conventional measures include using paints containing organic resins and solvents, using expensive additives, forming the base plate itself with a metal plate with excellent corrosion resistance, and roof tiles. It is not always sufficient in terms of environmental hygiene, tile construction, economy, and the like, such as providing a separate corrosion-resistant inner sheet between the base plate and the base plate.
そこで、本発明者らは、瓦自体の表面にコーティングされてこの瓦に優れた非透水性能を発現せしめると共に環境に優しい瓦用コーティング剤組成物について鋭意検討した結果、水性媒体中に、特定のアルキルトリアルコキシシランとジアルキルジアルコキシシランとを加水分解・共縮合させて得られたオルガノシロキサン共重合体と、光触媒活性を有する所定の金属酸化物と、テトラアルキルアンモニウムハライドからなる分散安定剤とを所定の割合で分散させてなるコーティング剤組成物を用いることにより、瓦に優れた非透水性能を付与できることを見出し、本発明を完成した。 Therefore, as a result of earnestly examining the environmentally friendly tile coating agent composition which is coated on the surface of the tile itself and exhibits the excellent water-impervious performance of the tile, the present inventors have found that a specific medium is contained in the aqueous medium. An organosiloxane copolymer obtained by hydrolysis and cocondensation of an alkyltrialkoxysilane and a dialkyldialkoxysilane, a predetermined metal oxide having photocatalytic activity, and a dispersion stabilizer comprising a tetraalkylammonium halide By using a coating agent composition dispersed at a predetermined ratio, it was found that excellent water-impervious performance can be imparted to the roof tile, and the present invention has been completed.
従って、本発明の目的は、瓦自体の表面にコーティングされてこの瓦に優れた非透水性能を発現せしめることができると共に環境に優しい瓦用コーティング剤組成物を提供することにある。 Accordingly, an object of the present invention is to provide an environmentally friendly coating agent composition for roof tiles that can be coated on the surface of the roof tile itself to exhibit excellent water-impervious performance.

Examples of the acid include hydrochloric acid, nitric acid, sulfuric acid, fluorine, and the like. Illustrative examples include mineral acids such as hydrofluoric acid and phosphoric acid, organic acids such as formic acid, acetic acid, propionic acid, lactic acid and paratoluenesulfonic acid, solid acids such as zeolite and H-type molecular sieves, and acidic ion exchange resins.

It is used in a proportion of 0.001% by weight or more and 0.1% by weight or less.
また、成分Aのオルガノシロキサン共重合体を調製する方法については、特に制限はないが、保存安定性を考慮して、好ましくはコーティング剤組成物を調製する直前に加水分解・共縮合させるのがよく、より好ましくは、一般式(1)のアルキルトリアルコキシシランと、一般式(2)のジアルキルジアルコキシシランと、無水条件下ではこれらアルキルトリアルコキシシラン及びジアルキルジアルコキシシランと反応しない加水分解触媒とを予め無水条件下で混合して成分A調製用混合物としておき、コーティング剤組成物の調製時にこの成分A調製用混合物を水性媒体中に添加し、成分Aのオルガノシロキサン共重合体を調製するのがよい。このように予め成分A調製用混合物としておくことにより、加水分解時に、一般式(1)のアルキルトリアルコキシシランと一般式(2)のジアルキルジアルコキシシランとが均一に共縮合するほか、高濃度で極微量の加水分解触媒を現場で添加する必要がないという利点がある。 In addition, the method for preparing the organosiloxane copolymer of component A is not particularly limited, but in consideration of storage stability, it is preferable to perform hydrolysis and cocondensation immediately before preparing the coating agent composition.
