Description
【０００１】
【産業上の利用分野】
本発明は、ＦＲＰ防水層を介在する磁器タイル張り工法に関する。
【０００２】
【従来の技術】
建築におけるタイル張り工法としては、外装タイル張りはセメントモルタル（またはポリマーディスパージョンを混入したセメントモルタル）による張付けが主流である。また、コンクリート打ち込みによりタイル張りを同時に行うタイル打ち込みコンクリートパネルも製造が盛んである。
【０００３】
また、内装タイル張り工法としては、有機接着剤による張付けが主流であり、ＪＩＳＡ５５４８で規格化されている陶磁器質タイル用接着剤は主成分により、合成ゴム系ラテックス型，合成樹脂系エマルジョン型，エポキシ変性合成ゴム系ラテックス型，エポキシ樹脂系反応硬化型などがある。また、タイル張りの改修工事では接着剤も利用されている。
【０００４】
【発明が解決しようとする課題】
しかし、セメントモルタルを使用した場合は、耐久性は期待できるが、接着力が低いために、経時後に、下地材や磁器タイルの熱膨張の差異などにより、施工が適切でなければ剥落する危険性がある。また、接着層が重くなり、自重が大きくなる欠点があった。更に、施工効率も低い。
【０００５】
また、有機接着剤による施工では、下地の湿潤状態での接着性及び接着後の耐水性や耐熱性などに問題があった。
【０００６】
本発明の目的は、施工に高い技能を要せずに、被着体の熱膨張の差異及び躯体の動きを吸収できて、しかも耐水性や耐熱性にも優れている磁器タイル張り工法を提供することにある。
【０００７】
【課題を解決するための手段】
本発明は、下地に磁器タイルを接着するに際して、ＦＲＰ防水層を介在して硬化後の伸び率が６００〜１０００％の一液湿気硬化型弾性ウレタン系接着剤で磁器タイルを接着するとともに、目地にセメント系の目地材を充填して仕上げたものであって、ＦＰＲ防水層はガラス繊維に不飽和ポリエステル樹脂を含浸して未硬化状態の表面に無機骨材を散布して付着させたものからなり、目地セメント割れが無い状態に仕上ることを特徴とする磁器タイル張り防火防水工法に関するものである。
【００１０】次に、図面及び実施例により本発明を説明する。
【実施例】
図１は、本発明による防火防水工法の施工後の構成断面図を示す。下地１に磁器タイル５を接着するのに、ＦＲＰ防水層２を介在して、硬化後の伸び率が６００〜１０００％の一液湿気硬化型弾性ウレタン系接着剤４を使用して施工する防火防水工法である。
【００１１】
ＦＲＰ防水層２は、ガラス繊維に不飽和ポリエステル樹脂を含浸した繊維強化プラスチック（ＦＲＰ）が適用でき、下地１にガラス繊維マツトを敷き、不飽和ポリエステル樹脂を塗布含浸して、未硬化のＦＲＰ防水層２表面に、硅砂等の無機骨材３を散布する方法が、ガラス繊維への不飽和ポリエステル樹脂の含浸性、ＦＲＰ防水層の強度、耐薬品性、耐久性及び次工程の一液湿気硬化型弾性ウレタン系接着剤４との密着性の点で最適である。
【００１２】
一液湿気硬化型弾性ウレタン系接着剤には、ポリエステルポリオール或いはポリエーテルポリオールとジイソシアネートから合成されるＮＣＯ末端ウレタンプレポリマーからなるものがあり、常温で硬化し、硬化後の伸び率が６００〜１０００％の弾性のあるものが適用される。
【００１３】
実施例１
厚さ１５ｍｍの合板からなる下地１に、一液湿気硬化型弾性ウレタン樹脂プライマー（ジョリエースＪＵ−１２７０、アイカ工業株式会社製）を０．２Ｋｇ／ｍ２塗布し、硬化後に、米坪４５０ｇ／ｍ２のカラス繊維マットを敷き、低粘度（約１０００ｃｐｓ／２５℃）の不飽和ポリエステル樹脂（ジョリエースＪＥ−２０００、アイカ工業株式会社製）を約１．５Ｋｇ／ｍ２含浸して、塗布ローラーと脱泡ローラーを用いて均して、厚さ約１．５ｍｍのＦＲＰ防水層２を形成した面に、再度、不飽和ポリエステル樹脂を約０．３Ｋｇ／ｍ２塗布して、未硬化状態の表面に５号硅砂からなる無機骨材３を約１．５Ｋｇ／ｍ２散布して、表面を硅砂で粗面とした。
【００１４】
次に、硬化後の伸び率が約６００％の弾性の一液湿気硬化型ウレタン樹脂接着剤（ジョリエースＪＵ−１３９０Ｎ、アイカ工業株式会社製）４を上記硅砂散布粗面に約１．５Ｋｇ／ｍ２をくし目状に塗布し、その上に厚さ８．５ｍｍ、９２ｍｍ角で目地幅９ｍｍの磁器タイル５を張付けた。接着剤の硬化後に、磁器タイルの目地をセメント系の目地材６を充填して磁器タイル張りパネルとした。
【００１５】
比較例１
実施例１において、弾性の一液湿気硬化型ウレタン樹脂接着剤（ジョリエースＪＵ−１３９０Ｎ）の代りに、硬化後の伸び率が３％以下の硬質のエポキシ樹脂接着剤（アイカアイボンＥＸ−７７７）を使用した以外は同様に施工してパネルとした。
【００１６】
比較例２
実施例１において、弾性のウレタン樹脂接着剤（ジョリエースＪＵ−１３９０Ｎ）の代りに、セメントモルタルを約２０ｍｍ厚さにコテ塗りした以外は同様に施工してパネルとした。
【００１７】
次に、実施例１，比較例１及び２の磁器タイル張りパネルを長さ６００ｍｍ、幅３００ｍｍの大きさにした試験片を用いて、図２に示す如く、スパン４５０ｍｍの中央部表面タイル目地部（表面側）、及び図３に示す如く、中央部裏面合板部（裏面側）に、それぞれ曲げ変位２，４，６，８，１０ｍｍの荷重で曲げ試験を行い、異状なし（０）、目地セメント割れ（１）、セメントモルタル層または接着層の破損（２）、磁器タイルの割れ（３）、のいずれかを目視で測定した結果を表１に示す。
【００１８】
【表１】
【発明の効果】
表１から明らかな如く、硬化後の伸び率が６００％以上の一液湿気硬化型弾性ウレタン系接着剤で施工した磁器タイル張りパネルは、曲げ変形荷重にも強く、表面側から荷重が負荷されても目地割れが発生しにくい。このため、磁器タイルの剥離や漏水などが発生しにくい。
一方、硬質のエポキシ接着剤で施工したもの、またはセメントモルタルで施工したものは、曲げ変形荷重に弱いために、破損箇所が目地セメント割れ以外に、接着層、又はセメントモルタル層、表面の磁器タイルにも発生している。
以上の点から、従来の施工方法に比べて格段の性能向上を図ることができる。
【００２０】
以上の如く、本発明の磁器タイル張り防火防水工法では、下地と磁器タイルとの熱膨張の差異や曲げ変形（歪み）を、介在する硬化後の伸び率が６００〜１０００％の一液湿気硬化型弾性ウレタン系接着剤が吸収するため目地割れ、接着層の破断、或いは磁器タイルの剥離などを回避できることから、信頼性の高い接着性能、防火防水性能を確保できる。
【００２１】
よって、ベランダ，屋上，バルコニーなどの防水防火工法として有用である。

[Industrial application fields]
The present invention relates to a porcelain tiling method with an FRP waterproof layer interposed.
[0002]
[Prior art]
As a tiling method in construction, exterior tiles are mainly applied with cement mortar (or cement mortar mixed with polymer dispersion). In addition, tiled concrete panels that are tiled simultaneously with concrete are also actively manufactured.
[0003]
In addition, as the interior tile tensioning method, the mainstream is an organic adhesive, and the ceramic tile adhesive standardized by JIS A5548 is composed mainly of synthetic rubber latex type, synthetic resin emulsion type, epoxy. There are modified synthetic rubber latex type and epoxy resin type reaction curing type. Adhesives are also used in tiled renovations.
[0004]
[Problems to be solved by the invention]
However, when cement mortar is used, durability can be expected, but due to the low adhesive strength, there is a risk that it will peel off if the construction is not appropriate due to differences in the thermal expansion of the base material and porcelain tile after the passage of time. There is. In addition, there is a drawback that the adhesive layer becomes heavy and its own weight increases. Furthermore, the construction efficiency is low.
[0005]
In addition, in the construction using the organic adhesive, there are problems in the adhesiveness in the wet state of the base and the water resistance and heat resistance after the adhesion.
[0006]
The object of the present invention is to provide a porcelain tiled construction method that can absorb the difference in thermal expansion of the adherend and the movement of the housing without requiring high skills for construction, and also has excellent water resistance and heat resistance. There is to do.
[0007]
[Means for Solving the Problems]
The present invention, when bonding the ceramic tiles to the substrate, as well as bond the porcelain tiles elongation after curing by intervening FRP waterproof layer is 600 to 1000% of the one-component moisture-cure elastic urethane adhesive, joint The FPR waterproof layer is made by impregnating glass fiber with unsaturated polyester resin and spraying inorganic aggregate on the uncured surface. Thus, the present invention relates to a fireproof waterproofing method for porcelain tiles, which is characterized in that it is finished without joint cement cracking .
The present invention will now be described with reference to the drawings and examples.
【Example】
FIG. 1 shows a cross-sectional view of a construction after construction of a fireproof and waterproof construction method according to the present invention. For bonding the
[0011]
The FRP waterproofing layer 2 can be applied with fiber reinforced plastic (FRP) in which a glass fiber is impregnated with an unsaturated polyester resin. A glass fiber mat is laid on the base 1, and an unsaturated polyester resin is applied and impregnated to provide an uncured FRP waterproofing. The method of spraying inorganic aggregate 3 such as cinnabar on the surface of layer 2 is the impregnation of unsaturated polyester resin into glass fiber, the strength of FRP waterproof layer, chemical resistance, durability and one-component moisture curing It is optimal in terms of adhesion to the mold elastic urethane adhesive 4.
[0012]
One-part moisture-curing type elastic urethane adhesives include NCO-terminated urethane prepolymers synthesized from polyester polyols or polyether polyols and diisocyanates, which are cured at room temperature and have an elongation rate of 600 to 1000 after curing. % Elastic is applied.
[0013]
Example 1
A one-part moisture-curing elastic urethane resin primer (Jolies JU-1270, manufactured by Aika Kogyo Co., Ltd.) is applied to a base 1 made of a 15 mm thick plywood, 0.2 kg / m 2 , and after curing, 450 g / m2 A m 2 crow fiber mat is laid and impregnated with about 1.5 kg / m 2 of a low viscosity (about 1000 cps / 25 ° C.) unsaturated polyester resin (Jolie's JE-2000, manufactured by Aika Kogyo Co., Ltd.). Apply an unsaturated polyester resin of about 0.3 Kg / m 2 again to the surface on which the FRP waterproofing layer 2 having a thickness of about 1.5 mm has been formed, About 1.5 kg / m 2 of inorganic aggregate 3 made of No. 5 cinnabar was sprayed on the surface, and the surface was roughened with cinnabar.
[0014]
Next, an elastic one-component moisture-curing urethane resin adhesive (Jolies JU-1390N, manufactured by Aika Kogyo Co., Ltd.) 4 having an elongation rate of about 600% after curing is applied to the rough surface of the cinnabar sand by about 1.5 kg / m 2 was applied in a comb shape, and a
[0015]
Comparative Example 1
In Example 1, instead of an elastic one-component moisture-curing urethane resin adhesive (Jolie JU-1390N), a hard epoxy resin adhesive (Eika Ivon EX-777) having an elongation percentage after curing of 3% or less The panel was constructed in the same manner except that was used.
[0016]
Comparative Example 2
In Example 1, in place of the elastic urethane resin adhesive (Jolie JU-1390N), a panel was made in the same manner except that a mortar was coated with a cement mortar to a thickness of about 20 mm.
[0017]
Next, using a test piece in which the porcelain tiled panels of Example 1 and Comparative Examples 1 and 2 have a length of 600 mm and a width of 300 mm, as shown in FIG. (Front side) and as shown in FIG. 3, a bending test was performed on the center back side plywood part (back side) with loads of bending displacements of 2, 4, 6, 8, and 10 mm, respectively. Table 1 shows the results of visual observation of any one of cement cracking (1), cement mortar layer or adhesive layer breakage (2), and porcelain tile cracking (3).
[0018]
[Table 1]
【The invention's effect】
As can be seen from Table 1, the porcelain tiled panel constructed with a one-component moisture-curing elastic urethane adhesive with an elongation after curing of 600% or more is resistant to bending deformation load and is loaded from the surface side. Even joint cracking is unlikely to occur. For this reason, peeling of porcelain tiles and water leakage are unlikely to occur.
On the other hand, those made with hard epoxy adhesive or those made with cement mortar are vulnerable to bending deformation load, so the damaged part is not only joint cement crack, but also adhesive layer, cement mortar layer, surface porcelain tile Has also occurred.
From the above points, the performance can be significantly improved as compared with the conventional construction method.
[0020]
As described above, in the fireproof waterproofing method with porcelain tiles according to the present invention, the difference in thermal expansion between the base and the porcelain tile and the bending deformation (distortion) are cured by a one-component moisture with an elongation rate after curing of 600 to 1000%. Since the type elastic urethane adhesive absorbs, it is possible to avoid joint cracks, breakage of the adhesive layer, peeling of porcelain tiles, and the like, so that highly reliable adhesion performance and fireproof waterproof performance can be ensured.
[0021]
Therefore, it is useful as a waterproof fireproofing method for verandas, rooftops, balconies, etc.
