Description
本発明は、建築物に用いられる目地材に関する。 The present invention relates to a joint material used for a building.
コンクリート建造物の壁面や柱の外周面への大型タイルの取付けは、金物を躯体コンクリートに取り付け、大型タイルを金物に固定することによって行われており、このようなタイルの目地部には、一般に、樹脂系目地材が使用されている。 Large tiles are attached to the walls of concrete buildings and the outer peripheral surfaces of pillars by attaching hardware to the concrete and fixing the large tiles to the hardware. Resin-based joint materials are used.
上記樹脂系目地材としては、防水パンやタイル施工に用いられる、シリコーン系目地材、変性シリコーン系目地材、ウレタン系目地材、及びエポキシ樹脂系目地材が知られているが、シリコーン系目地材、変性シリコーン系目地材及びウレタン系目地材には、ゴム弾性があり、柔軟性が大き過ぎるため、耐久性が十分でなく、歪み易いという問題があった。また、上記エポキシ樹脂系目地材は、剛性が高いため割れが生じやすく、施工時にダレ等を壁面に付着させずに平滑に仕上げることや、施工後に目地材がタイル面にはみ出したとき拭き取ることが難しい。
これに対し、脂環式エポキシ樹脂等をバインダー成分として配合したタイル用目地材や（特許文献１）、エポキシ樹脂系目地材を用いるとともに、タイルをユニット状にすること（特許文献２）が提案されているが、タイル面に一度エポキシ樹脂系目地材がはみ出すと拭き取りが難しいことに変わりはなく、施工後の清掃に未だ多くの手間がかかっており、施工性も十分には改善されていない。
As the resin joint material, silicone joint material, modified silicone joint material, urethane joint material and epoxy resin joint material used for waterproofing pan and tile construction are known. Silicone joint material The modified silicone-based joint material and the urethane-based joint material have rubber elasticity and are too flexible so that there is a problem that durability is not sufficient and distortion is easily caused. In addition, the epoxy resin joint material has high rigidity and is prone to cracking, so that it can be finished smoothly without causing dripping or the like to adhere to the wall surface during construction, or can be wiped off when the joint material protrudes from the tile surface after construction. difficult.
On the other hand, the joint material for tiles (Patent Document 1) and epoxy resin joint material containing alicyclic epoxy resin or the like as a binder component and the unitization of tiles (Patent Document 2) are proposed. However, once the epoxy resin joint material protrudes from the tile surface, wiping is still difficult, and much work is still required for cleaning after construction, and workability has not been improved sufficiently. .
一方、上記樹脂系目地材の他に、セメントや細骨材等を混合したセメント系目地材が知られている。セメント系目地材を、水と添加して混練してスラリー状とし、石材等の目地間隙に充填することによって、目地を形成できる。 On the other hand, in addition to the resin joint material, a cement joint material in which cement, fine aggregate, or the like is mixed is known. A joint material can be formed by adding cement-based joint material with water and kneading it to form a slurry and filling the joint space such as stone.
しかしながら、繊維補強ポリマーセメントモルタル等の従来のセメント系目地材は、用水路、ダム等の斜面や、擬岩パネルの補強（特許文献３）等に用いられているものの、マンション、ホテル等の建築物の外壁・内壁の目地に使用するためには、耐久性の向上が望まれるものであった。
また、セメント系目地材には、吸水量の低減が要求されるため、所定量のポリマーが配合されているが、一般に、ポリマーを入れすぎると、目地が汚れやすく、建築物の外壁・内壁に使用した場合、タイル面にはみ出した目地材を施工後に拭き取るのが難しいという問題があった。
したがって、本発明の課題は、施工性、施工後の拭き取り性及び耐久性に優れ、吸水量が低減された建築用目地材の提供にある。
However, conventional cement-based joint materials such as fiber-reinforced polymer cement mortars are used for slopes of irrigation channels, dams, and artificial rock panels (Patent Document 3). In order to use it for joints on the outer and inner walls, it was desired to improve durability.
In addition, since cement-based joint materials are required to reduce the amount of water absorption, a predetermined amount of polymer is blended. Generally, however, if too much polymer is added, the joints are easily soiled, and the outer and inner walls of the building are contaminated. When used, there is a problem that it is difficult to wipe off the joint material that protrudes from the tile surface after construction.
Therefore, the subject of this invention exists in provision of the joint material for constructions which was excellent in workability | operativity, the wiping property after construction, and durability, and the water absorption amount was reduced.
そこで、本発明者らは、鋭意検討した結果、セメント、細骨材、保水剤、高性能減水剤又は高性能ＡＥ減水剤、及び撥水剤に、耐アルカリ性繊維とポリマーとを特定の質量比率で含有せしめることにより、施工性、施工後の拭き取り性及び耐久性に優れ、吸水量が低減された建築用目地材が得られることを見出した。 Therefore, as a result of intensive studies, the present inventors have determined that a specific mass ratio of alkali-resistant fiber and polymer to cement, fine aggregate, water retention agent, high performance water reducing agent or high performance AE water reducing agent, and water repellent agent. It was found that by containing it in the construction, a joint material for construction having excellent workability, wiping property after construction and durability and reduced water absorption can be obtained.
すなわち、本発明は、（Ａ）セメント、（Ｂ）細骨材、（Ｃ）保水剤、（Ｄ）高性能減水剤又は高性能ＡＥ減水剤、（Ｅ）撥水剤、（Ｆ）耐アルカリ性繊維、及び（Ｇ）ポリマーを含有し、成分（Ｆ）と成分（Ｇ）との質量比〔成分（Ｆ）／成分（Ｇ）〕が、０．２５〜１．６である建築用目地材を提供するものである。 That is, the present invention includes (A) cement, (B) fine aggregate, (C) water retention agent, (D) high-performance water reducing agent or high-performance AE water reducing agent, (E) water repellent, and (F) alkali resistance.

-Flow value The flow value (mm) was measured twice according to JISR5201 in the test room of 20 degreeC, and this average value (mm) was calculated | required. If this value was 195 to 220 mm, it was judged as “good”.
Unit Volume Mass A unit volume mass (kg / L) was measured according to JIS A 1171 in a test chamber at 20 ° C. using a 500 mL stainless steel container. If this value was 1.80 to 2.15 kg / L, it was judged as “good”.
-Water retention rate In a 20 degreeC test room, according to the public building association standard "ready-made compound joint material" water retention, the water retention rate (%) was measured with the filter paper method using the 5A filter paper. If this value was 30% or more, it was judged as “good”.
-Bending strength It shape | molded in accordance with JISR5201 using a 4x4x16cm formwork in a 20 degreeC test chamber, and it demolded after carrying out a wet air curing in a curing tank of 20 degreeC80% RH for 24 hours. Then, it was cured in the air in a test room at 20 ° C. and 60% RH for 6 days, the bending strength of 3 specimens was measured at a material age of 7 days, and this average value (N / mm 2 ) was determined. If this value was 2.0 to 6.0 N / mm 2 , it was judged as “good”.
-Compressive strength The compressive strength of the three specimens after the end of the bending strength test was measured, and the average value (N / mm 2 ) was determined. If this value was 5.0-40 N / mm 2 , it was judged as “good”.

×：コテへ目地材が付着し、目地部への充填性が悪く、充填後目地部が膨らむ。
２）充填性
○：仕上がり面が平滑で、未充填部分もない。
△：仕上がり面が平滑でないが、未充填部分はない。
×：仕上がり面が平滑でなく、未充填部分もある。
-Workability In a test room at 20 ° C, 150 g / m 2 of a 5-fold solution of moltop emulsion was applied to a 300 x 300 x 60 mm concrete plate, and a 45-square mosaic tile was made by 1 sheet Pacific Material Co., Ltd. 24 hours later. Tightened with tile mortar K. After 48 hours, it was smeared with a rubber iron and the workability was evaluated according to the following criteria.
1) Iron workability and little sagging ◎: No joint material adheres to the iron, the iron elongation is very good, and there is no swelling of the joint after filling into the joint.
○: The joint material hardly adheres to the iron, the iron elongation is good, and there is no swelling of the joint after filling the joint.
X: The joint material adheres to the iron, the filling property to the joint part is poor, and the joint part swells after filling.
2) Fillability ○: The finished surface is smooth and there is no unfilled portion.
Δ: Finished surface is not smooth, but there is no unfilled portion.
X: The finished surface is not smooth and there are also unfilled parts.
・拭き取り性
上記の施工性試験によって施工された壁面を清掃し、拭き取り性を評価した。
○：タイル面、目地部いずれにも拭き残りがない。
×：タイル面、目地部のいずれかに拭き取れない箇所がある。
-Wiping property The wall surface constructed | assembled by said workability test was cleaned, and the wiping property was evaluated.
○: There is no wiping residue on both the tile surface and joints.
X: There is a portion that cannot be wiped off either on the tile surface or the joint.
・吸水量
上記曲げ強度測定で用いた供試体と同様にして作製した４×４×１６ｃｍの材齢２８日供試体を用い、ＪＩＳ Ａ １４０１に従い、２４時間後の吸水量を測定した。供試体は３本とし、この平均値（ｇ）を求めた。
○：吸水量が２０ｇ以下である。
×：吸水量が２０ｇを超えた。
-Water absorption amount The water absorption amount after 24 hours was measured according to JISA1401 using the 4x4x16cm specimen 28-day specimen produced similarly to the specimen used by the said bending strength measurement. Three specimens were used, and the average value (g) was determined.
○: Water absorption is 20 g or less.
X: The amount of water absorption exceeded 20g.
前記試験の結果を、以下の表３に示す。 The results of the test are shown in Table 3 below.
表３に示すように、実施例１〜１１の建築用目地材は、施工性、施工後の拭き取り性及び耐久性に優れ、吸水量が少ない。 As shown in Table 3, the building joint materials of Examples 1 to 11 are excellent in workability, wiping property after work and durability, and have a small amount of water absorption.
