An adhesive cleaner according to Example 3 was constructed in the same manner as Example 1 except that the above single-sided adhesive sheet was used.
各例に係る片面粘着シートを150mm×150mm(粘着性表面の面積0.0225m2)の大きさにカットして試験用サンプルを作成した。この試験用サンプルを、図1,2に示す粘着クリーナー10の粘着シートロール(直径48mm、幅160mm)30の外表面(外周面)の全体にその粘着性表面が外側となるように貼り付けることにより、試験用クリーナーを作製した。この試験用クリーナーは、転動部材(重量26.5g程度)40と取っ手52とがポリプロピレン製で、把持部材50の棒状部分は直径が5mmのステンレス鋼製部材であった。また、試験用クリーナーの全長は凡そ40cm、総重量は約241g、粘着シートロール30の重量は約113g、クリーナー主部材15の重量は約128gであった。粘着シートロール30は、例2に係る片面粘着シートを紙製の円筒状保持部材に厚さ約1cm程度になるまで巻回することにより形成したものである。
また、試験に供する水性固形屑サンプルを用意した。水性固形屑サンプルとしては、骨材としての珪砂に、該珪砂100重量部に対して20重量部の割合で界面活性剤水溶液を添加し、ビニル袋内でよく振って水溶液が珪砂全体に均一に行き渡るようにしたものを用意した。珪砂としては、新東陶料社製のカラー骨材(商品名:シントーカラーサンド34シリーズ、中心粒径1.20~1.50mm、粒度規格0.5~2.4mm)を用いた。界面活性剤水溶液としては、5重量%の界面活性剤(40%ラウリル硫酸トリエタノールアミン溶液(和光純薬工業社製))を水(蒸留水)に溶解した水溶液を用いた。
上記で用意した水性固形屑サンプル200gを、トレイ(240mm×320mmのステンレス製のトレイ)の平坦な底面全体に広がるように均一に配置した。図4に示すように、この水性固形屑サンプル100を配置したトレイTに、作製した試験用クリーナー10’の粘着性表面32Aを接触させて転がし、上記トレイTの長手方向の一端から他端までの範囲を2往復移動させることで、粘着性表面32Aに水性固形屑サンプル100を付着させた。
水性固形屑サンプル100を付着させた後の試験用クリーナー10’の重量W1(g)を測定し、予め測定しておいた試験用クリーナー10’の初期重量W0(g)との差から水性固形屑サンプルの付着量W2(W2(g)=W1-W0)を求め、W2(g)を試験用サンプルの露出した粘着性表面32Aの面積(m2)で除すことにより、粘着性表面1m2当たりの水性固形屑サンプル付着量AC(g/m2)を求めた。上記試験は各例につき5回行い、その平均値を記録した。結果を表1に示す。また、各例につき、水性固形屑サンプル付着後の状態を撮影した画像を図6,7,8に示す。 [Aqueous solid waste adhesion test]
A single-sided pressure-sensitive adhesive sheet according to each example was cut into a size of 150 mm × 150 mm (area of adhesive surface 0.0225 m 2 ) to prepare a test sample. This test sample is affixed to the entire outer surface (outer peripheral surface) of the adhesive sheet roll (diameter 48 mm, width 160 mm) 30 of the
Moreover, the aqueous | water-based solid waste sample used for a test was prepared. As an aqueous solid waste sample, a surfactant aqueous solution is added to silica sand as an aggregate at a ratio of 20 parts by weight with respect to 100 parts by weight of the silica sand, and shaken well in a vinyl bag so that the aqueous solution is uniformly distributed throughout the silica sand. I prepared something to go around. As the silica sand, a color aggregate (trade name: Shinto Color Sand 34 series, center particle size 1.20 to 1.50 mm, particle size standard 0.5 to 2.4 mm) manufactured by Shinto Ceramics Co., Ltd. was used. As the surfactant aqueous solution, an aqueous solution in which 5% by weight of a surfactant (40% lauryl sulfate triethanolamine solution (manufactured by Wako Pure Chemical Industries, Ltd.)) was dissolved in water (distilled water) was used.
The aqueous solid waste sample 200 g prepared above was uniformly arranged so as to spread over the entire flat bottom surface of the tray (240 mm × 320 mm stainless steel tray). As shown in FIG. 4, the
The weight W1 (g) of the test cleaner 10 'after the aqueous
上述の水性固形屑付着試験を行った後、連続して水性固形屑脱落試験を下記の要領で行った。図5の(a)に示すように、プラスチックからなる硬質平坦面G上にて、試験用クリーナー10’の粘着シートロール30をその円筒軸方向を垂直とし、かつ粘着シートロール30の下端が上記硬質平坦面Gから5cmの高さ(図5の(a)中の符号hで示す高さ)となるように、把持部材50の取っ手52側の端部を治具Jに上下方向に回動自在となるように固定した。粘着シートロール30の下端と硬質平坦面Gとの間には、スペーサ(図示せず)を配置し、試験用クリーナー10’を上記の高さに保持した。そして、上記スペーサを粘着シートロール30と硬質平坦面Gとの間から抜きとり、図5の(b)に示すように、試験用クリーナー10’の粘着シートロール30側を落下させた。より具体的には、図5の(b)中の矢印A方向に自由落下に近い状態で落下させた。落下後の試験用クリーナー10’の重量W4(g)を測定し、予め測定しておいた落下前の試験用クリーナー10’の重量W3との差から上記落下後の水性固形屑サンプル脱落量W5(W5(g)=W3-W4)を求めた。そして、式:
AD(%)=W5/(W3-W0)×100
;から、水性固形屑サンプル脱落率AD(%)を求めた。なお、各例において、W3とW1とは同じ値であった。上記試験は各例につき5回行い、その平均値を記録した。結果を表1に示す。 [Aqueous solid waste removal test]
After performing the above-mentioned aqueous solid waste adhesion test, an aqueous solid waste removal test was continuously performed in the following manner. As shown in FIG. 5A, on the hard flat surface G made of plastic, the pressure-sensitive
A D (%) = W5 / (W3-W0) × 100
From this, an aqueous solid waste sample dropout rate A D (%) was determined. In each example, W3 and W1 were the same value. The above test was performed 5 times for each example, and the average value was recorded. The results are shown in Table 1.
各例に係る粘着シートを200mm×20mmにカットして長方形状の試験片を用意した。上記試験片の粘着面(粘着性表面)をステンレス鋼(SUS304)板に2kgのローラーを一往復させて貼り付け、これを23℃、RH50%の環境下に30分間保持した後、引張試験機を用い、JIS Z0237に準拠して、23℃、RH50%の環境下、剥離角度180度、引張速度300mm/分の条件にて、対SUS180度剥離強度(N/20mm)を測定した。測定は、島津製作所社製の「テンシロン」を用いて行った。結果を表1に示す。 [180 degree peel strength]
The pressure-sensitive adhesive sheet according to each example was cut into 200 mm × 20 mm to prepare a rectangular test piece. The adhesive surface (adhesive surface) of the test piece was attached to a stainless steel (SUS304) plate by reciprocating a 2 kg roller and held in an environment of 23 ° C. and
