Description
本發明係關於有效使用於例如粗面塗裝用遮蔽膠帶等用途,剝離作業性優異、且粗面接著性、耐水性及耐寒性等諸項特性均優異的黏著帶。 The present invention relates to an adhesive tape that is effectively used in applications such as masking tapes for rough coating, has excellent peeling workability, and has excellent properties such as rough surface adhesion, water resistance, and cold resistance.
習知在黏著劑層設有非黏著劑部分的黏著帶已被使用於各種用途。例如專利文獻1~6記載有塗裝用遮蔽膠帶,說明藉由將非黏著劑部分使用為抓持區便可輕易剝離黏著帶。專利文獻7記載有側端部無塗佈黏著帶,說明藉由利用非黏著劑部分,便可使黏著劑對受黏物輕易地進行再剝離、再黏貼。專利文獻8記載有將收納有蔬菜束之捆束、食品的塑料袋等較輕物予以捆束用的黏著帶,係可輕易利用手指朝與長邊方向正交之方向切斷之捆束用黏著帶,有說明於撕裂黏著帶時,為了由手指勾住非黏著劑部便可輕易施行撕裂作業而設計。另一方面,專利文獻9記載有裝飾用遮蔽膠帶,說明藉由在中央處設置非黏著劑部分,而設置未接觸到黏著劑的筒狀或袋狀空間,便可在其中插入物體。又,專利文獻10記載有將濺鍍靶的靶材與背板材利用焊料接合時,為遮蔽住多餘焊料而使用的遮蔽用黏著帶,有說明將非黏著劑部分使用為脫氣通路。又,專利文獻11記載有電池用黏著帶,有說明為防止從基材發生糊滲出,便在基材的二側端緣部設計非黏著劑部分。
The conventional adhesive tape provided with a non-adhesive part on the adhesive layer has been used for various purposes. For example,
就此種黏著帶所使用的黏著劑,特別提案有溶劑系黏著劑(專利文獻5、6、7、8、11)。但是,溶劑系黏著劑若加厚黏著劑層,則在加熱、乾燥步驟中會產生發泡等,因而必須削薄。此情況,受黏物較難對道路等粗面進行接著。又,若未施加壓接力則黏貼性偏低,因而較難在天花板等高處及鷹架處施工。又,因為對水濕潤地方的黏貼性偏低或低溫下的接著性偏低,因而較難在下雨後或冬季、寒冷地施工。又,習知黏著帶亦必須更加提升剝離作業性。
Regarding the adhesive used in such an adhesive tape, a solvent-based adhesive has been specifically proposed (

互形成。因此,在黏著帶的切斷端面其中一部分與側面均存在有抓持區,因而從哪一部分均可輕易剝離。且,由非黏著劑部分1與黏著劑部分2所構成之圖案,當捲取黏著帶形成膠帶捲時,成為非黏著劑部分與黏著劑部分的膠帶厚度差全部或其中一部分相抵消的圖案,因黏著劑存在而造成的壓力不會在捲取方向上集中於特定地方,因而黏著帶的切面漂亮,膠帶捲的外圍表面較平滑,不易發生捲繞崩潰。該等各情形,容在後述實施例中詳細說明。

圖2所示係本發明的黏著帶一實施形態的示意平面圖。本實施形態中,非黏著劑部分1係平行於膠帶寬度方向設置。因此,在黏著帶的側面存在有抓持區,因而可輕易從側面剝離。又,若在非黏著劑部分1的地方切斷,則亦可從切斷端面輕易地剝離。且,由非黏著劑部分1與黏著劑部分2所構成的圖案,係形成在捲取黏著帶形成膠帶捲時,非黏著劑部分與黏著劑部分的膠帶厚度差之全部或其中一部分相抵消的圖案,因為在捲取方向上不會有捲繞壓集中之情形而呈分散狀態,因而黏著帶的切面漂亮,膠帶捲的外圍表面較平滑,不易發生捲繞崩潰。該等各情形,容在後述實施例中詳細說明。又,例如藉由調整非黏著劑部分1的寬度,使膠帶正交的對象物接觸到非黏著劑部分1,並使對象物周圍的構件接觸到黏著劑部分2,亦可使對象物在不會附著到黏著劑之狀態下固定。

圖3所示係本發明的黏著帶一實施形態的示意平面圖。本實施形態中,沿黏著帶的長度方向在二側端部設置非黏著劑部分1。因此,在黏著帶切斷端面二側端部及側面存在有抓持區,因而不管從何處均可輕易剝離。又,例如當為將對象物簡易固定等而設置時,便可抓住二側端部的非黏著劑部分1而簡單設置。

圖4所示係本發明的黏著帶一實施形態的示意平面圖。本實施形態中,沿黏著帶的長度方向在中央處設置非黏著劑部分1。因此,在黏著帶切斷端面中央處存在有抓持區,因而可輕易從切斷端面剝離。又,例如使用於例如瓦楞紙箱等捆包箱的密封時,在紙箱開封時若利用切割刀切斷中央處的非黏著劑部分1,則黏著劑不會附著於切割刀上。又,即便利用瓦楞紙箱進行的捆包地方有出現間隙,但內容物仍不會有黏著劑附著。

[黏著力] [Adhesion]
根據JIS Z 0237(2000),測定寬25mm黏著帶對SUS板的黏著力。 According to JIS Z 0237 (2000), the adhesive force of the adhesive tape with a width of 25 mm to the SUS board was measured.
[對粗面的黏著力] [Adhesion to rough surface]
想像例如道路等粗面,製作將#400研磨紙固定於SUS板上的 試驗板。根據JIS Z 0237(2000),測定寬25mm黏著帶對試驗板研磨紙面的黏著力。 Imagine rough surfaces such as roads and make #400 abrasive paper fixed on a SUS plate Test board. According to JIS Z 0237 (2000), the adhesive force of the adhesive tape with a width of 25 mm to the ground paper surface of the test plate was measured.

As shown in FIG. 5, the
[對潤濕粗面的黏著力] [Adhesion to wet rough surface]
想像例如道路等粗面,準備將#280研磨紙固定於SUS板上(研磨面朝上)的試驗板。試驗片在水中浸漬3分鐘後取出,用手甩該試驗板而除去水滴後,根據JIS Z 0237(2000),測定寬25mm黏著帶對試驗板的黏著力。 Imagine a rough surface such as a road, and prepare a test board with #280 abrasive paper fixed to a SUS board (the abrasive surface is facing upward). The test piece was immersed in water for 3 minutes and then taken out. After shaking the test board by hand to remove water droplets, the adhesive force of the adhesive tape with a width of 25 mm to the test board was measured in accordance with JIS Z 0237 (2000).
[低溫環境下的定荷重剝離] [Constant load peeling under low temperature environment]
想像在寒冷地使用,於-20℃環境下施行定荷重剝離測定。使JIS Z 0237(2000)所規定的SUS板,依寬25mm×長50mm的面積接 著試驗膠帶,在膠帶的端部懸吊300g錘。測定1分鐘的剝落距離,或當在1分鐘內便全部剝離時便測定該時間。 Imagine using it in a cold place and performing a constant-load peel test at -20°C. Connect the SUS board specified in JIS Z 0237 (2000) in an area of 25mm in width x 50mm in length Wear the test tape, and hang a 300g hammer on the end of the tape. Measure the peeling distance for 1 minute, or measure the time when all peeling occurs within 1 minute.
[殘留溶劑] [remaining solvent]
黏著劑層中的殘留溶劑係使用島津製作所(股)製氣相色層分析儀,依頂部空間法(加熱條件:80℃、40分)測定揮發檢測到的殘留溶劑量。 The residual solvent in the adhesive layer was measured by a headspace method (heating conditions: 80°C, 40 minutes) using a gas chromatography analyzer manufactured by Shimadzu Corporation.
<黏著劑之評價結果> <Evaluation Results of Adhesives>
由表1所示之結果得知,參考例1~7之黏著帶由固態黏著劑組成物所構成的黏著劑層,幾乎所有項目均優異。例如因為通常對粗面及下雨後尚未充分乾燥之粗面的黏著力均優異,因而可理解為對通常的道路與潤濕之道路可獲得充分的固定力,且因為傾斜30°黏性與環形初黏性均優異,因而可理解為即便未施加壓接仍可獲得充分的固定力,又因為低溫環境下的定荷重剝離優異,因而可理解為即便冬季仍不易剝離,又因為殘留溶劑少,因而不易發生環境汚染。 From the results shown in Table 1, it can be seen that the adhesive layers of the adhesive tapes of Reference Examples 1-7 are excellent in almost all items. For example, because it usually has excellent adhesion to rough surfaces and rough surfaces that have not been sufficiently dried after rain, it can be understood that sufficient fixing power can be obtained for normal roads and wet roads, and because of the 30° inclination of viscosity and ring shape The initial tack is excellent, so it can be understood that a sufficient fixing force can be obtained even if the crimping is not applied, and because the constant load peeling is excellent in a low temperature environment, it can be understood that it is not easy to peel even in winter, and because there is little residual solvent, Therefore, environmental pollution is unlikely to occur.
另一方面,比較參考例1~2之黏著帶之由溶劑系黏著劑組成物所構成的黏著劑層,幾乎所有項目均遜於參考例1~7。例如黏著力、黏性、定荷重剝離較差的原因之一,可認為係黏著層厚度較參考例1~7薄。另一方面,比較參考例3雖嘗試將黏著劑層厚度設為與參考例3及5相同的0.11mm,但卻因為溶劑系黏著劑組成物出現發泡導致無法製作適當的黏著帶。當如此使用溶劑系黏著劑組成物時,頗難加厚黏著劑層的厚度。 On the other hand, the adhesive layer composed of the solvent-based adhesive composition of the adhesive tapes of Comparative Reference Examples 1 to 2 is inferior to Reference Examples 1 to 7 in almost all items. For example, one of the reasons for the poor adhesion, tackiness and constant-load peeling is that the thickness of the adhesive layer is thinner than that of Reference Examples 1-7. On the other hand, Comparative Reference Example 3 tried to set the thickness of the adhesive layer to 0.11 mm, which is the same as that of Reference Examples 3 and 5. However, the solvent-based adhesive composition was foamed and an appropriate adhesive tape could not be produced. When the solvent-based adhesive composition is used in this way, it is quite difficult to increase the thickness of the adhesive layer.
<剝離作業性的評價試驗> <Evaluation test of peeling workability>
製作以下實施例1~4及比較例1的黏著帶,並依照以下方法評價黏著帶的剝離作業性。結果如表3所示。 The adhesive tapes of the following Examples 1 to 4 and Comparative Example 1 were produced, and the peeling workability of the adhesive tape was evaluated according to the following method. The results are shown in Table 3.
[實施例1] [Example 1]

依照與參考例2同樣地全面塗佈黏著劑,而製作寬25mm的黏著帶。 The adhesive was applied to the entire surface in the same manner as in Reference Example 2, and an adhesive tape with a width of 25 mm was produced.

[◎]:容易剝離。 [◎]: Easy to peel off.
[○]:略容易剝離。 [○]: Slightly easy to peel off.
[×]:不易剝離。 [×]: Not easy to peel off.
<剝離作業性之評價結果> <Evaluation result of peeling workability>
由表3所示結果得知,實施例1~4的黏著帶因為非黏著劑部分1成為抓持區,因而剝離作業性佳。具體而言,實施例1的黏著帶(圖1)不管在哪種場所切斷時,均可從抓持區輕易剝離。實施例2的黏著帶(圖2)係依非黏著面位於末端的方式切斷時,可輕易從抓持區剝離。實施例3的黏著帶(圖3)係不管在哪種場所切斷時,均可從抓持區輕易剝離。實施例4的黏著帶(圖4)因為抓持區位於中央處,因而相較於實施例1~3的黏著帶雖呈現稍微難剝離,但相較於比較例1的黏著帶卻顯得格外容易剝離。另一方面,因為比較例1的黏著帶並沒有抓持區,因而不易剝離。
From the results shown in Table 3, it is known that the adhesive tapes of Examples 1 to 4 have good peeling workability because the
另外,實施例1~4的黏著帶因為設有非黏著劑部分1,因而相較於參考例3之下,雖黏著力與黏性呈現若干降低,但即便如此卻具有遠較使用溶劑系黏著劑組成物的比較例1優異之黏著力、黏性。
In addition, since the adhesive tapes of Examples 1 to 4 are provided with the
<膠帶捲外觀與經時變化之評價試驗> <Evaluation test of tape roll appearance and changes over time>
針對實施例1~4的黏著帶之膠帶捲外觀與經時變化,依照以下方法施行評價。具體而言,將黏著帶依如圖6的上側所示捲取於紙管上而形成膠帶捲6(寬25mm、捲繞長度25m或300m)、目視觀察膠帶捲6的外圍表面、膠帶端部的切面,依照以下基準施行評價。又,將膠帶捲6的紙管懸吊於軸上,於40℃下放置1週,目視確認有無如圖6中的下側所示捲繞崩潰(碗狀變形)情形,依照以下基準評價。結果如表4所示。
Regarding the appearance and changes with time of the tape roll of the adhesive tapes of Examples 1 to 4, evaluation was performed according to the following methods. Specifically, the adhesive tape is wound on a paper tube as shown in the upper side of Figure 6 to form a tape roll 6 (width 25mm, winding length 25m or 300m), visually observe the outer surface of the
[◎]:外圍表面及切面均沒有問題,且沒有發生捲繞崩潰。 [◎]: There is no problem with the outer surface and the cut surface, and no winding collapse occurs.
[○]:外圍表面及切面雖略有問題,但沒有發生捲繞崩潰。 [○]: Although there is a slight problem on the outer surface and the cut surface, no winding collapse occurred.

[×]:外圍表面及切面出現大問題,且有發生捲繞崩潰。 [×]: There are major problems with the outer surface and the cut surface, and the winding collapse occurs.
<膠帶捲的耐捲繞崩潰評價結果> <Evaluation results of resistance to winding and collapse of tape rolls>
由表4所示結果得知,實施例1的黏著帶(圖1)及實施例2的黏著帶(圖2),係膠帶捲6的外圍表面及切面均無問題,且沒有發生捲繞崩潰。另一方面,實施例3的黏著帶(圖3)及實施例4的黏著帶(圖4),在膠帶捲6捲繞25m時,外圍表面及切面有略出現問題,在膠帶捲6捲繞300m時亦有發生捲繞崩潰。
According to the results shown in Table 4, the adhesive tape of Example 1 (Figure 1) and the adhesive tape of Example 2 (Figure 2) have no problems with the outer surface and cut surface of the
具體而言,實施例3的黏著帶(圖3)及實施例4的黏著帶(圖4),因為在捲取方向上具有由非黏著劑部分1及黏著劑部分2於二端部或中央處呈連續的圖案,若將其捲取形成膠帶捲6,則因二部位1及2的膠帶厚度差相乘,導致在膠帶捲6的外圍表面出現凹凸。另一方面,實施例1的黏著帶(圖1)及實施例2的黏著帶(圖2),因為由非黏著劑部分1及黏著劑部分2所構成之圖案在捲取方向上並非連續,因而若將其捲取形成膠帶捲6,則二部位1及2的膠帶厚度差相抵消,使膠帶捲6的外圍表面呈平滑。
Specifically, the adhesive tape of Example 3 (Figure 3) and the adhesive tape of Example 4 (Figure 4) have a
實施例3的黏著帶(圖3)及實施例4的黏著帶(圖4),因為具有在捲取方向上,非黏著劑部分1及黏著劑部分2於二端部或中央處呈連續的圖案,因而若將其捲取300m形成膠帶捲6,則因二部位1及2的膠帶厚度差所造成之黏著力差會產生較大的相乘效應,經在40℃下懸吊1週後便發生捲繞崩潰。另一方面,實施例1的黏著帶(圖1)及實施例2的黏著帶(圖2),因為由非黏著劑部分1及黏著劑部分2所構成圖案在捲取方向上並非連續,因而即便將其捲取300m形成膠帶捲6,二部位1及2的黏著力差異會相抵消,即便在40℃下懸吊1週仍不會發生捲繞崩潰。
The adhesive tape of Example 3 (Figure 3) and the adhesive tape of Example 4 (Figure 4) have the
(產業上之可利用性) (Industrial availability)
本發明的黏著帶係可毫無限制地使用於各種用途,針對使用後需剝離的用途(例如:道路、牆壁等粗面塗裝用遮蔽膠帶等等用途)非常有用。又,針對各種工程用暫時固定、臨時固定用膠帶亦非常有用。又,亦頗適用於存在有不欲使受黏物接觸到黏著劑之處的情況。 The adhesive tape of the present invention can be used for various purposes without limitation, and is very useful for applications that need to be peeled off after use (for example, masking tape for rough coating of roads, walls, etc.). It is also very useful for temporary fixation and temporary fixation tapes for various constructions. In addition, it is also quite suitable for situations where there is a place where you do not want the adherend to come into contact with the adhesive.
