The volume resistivity of the coating layer measured in accordance with JIS C 2139:2008 is 1.0×10 17 Ω·cm or less, and the surface free energy calculated based on the contact angle measured in accordance with JIS R 3257:1999 is 36.6 mJ/m 2 the following.
Description
本發明是有關於一種被覆金屬板、具有其的接合器及防黏結膠帶。 The invention relates to a clad metal plate, an adapter with it and an anti-bonding tape.
接合器用於建築物外包裝中的外包裝板間的接縫部。接合器具有以一定的間隔保持外包裝板的功能。 The adapter is used for the seams between the outer packaging panels in the outer packaging of buildings. The adapter has a function of holding the outer packaging board at a constant interval.
於外包裝板間的接縫部填充有填隙材料,以保證防水性及氣密性。此時,若填隙材料和兩個外包裝板的側端面與接合器進行三面接著,則外包裝板會根據外部環境的變化(特別是溫度變化)進行伸縮,因此填隙材料無法追隨外包裝板的伸縮,由外包裝板的伸縮所產生的應力集中於填隙材料,導致填隙材料容易斷裂。 The joints between the outer packaging boards are filled with gap filling materials to ensure waterproof and airtightness. At this time, if the caulking material and the side end surfaces of the two outer packaging panels are three-sidedly bonded to the adapter, the outer packaging panels will expand and contract according to changes in the external environment (especially temperature changes), so the caulking material cannot follow the outer packaging. The expansion and contraction of the board, the stress generated by the expansion and contraction of the outer packaging board concentrates on the gap material, causing the gap material to break easily.
為了消除此種問題,使填隙材料與相鄰的兩個外包裝板的側端面進行接著,但不與接合器進行接著,即進行兩面接著。 In order to solve such a problem, the caulking material is bonded to the side end surfaces of two adjacent outer packaging panels, but is not bonded to the adapter, that is, bonded on both sides.
作為進行兩面接著的方法,正在研究於接合器的與填隙材料相接的面(填隙材料的承受部)形成相對於填隙材料而接著性低的塗膜的方法。例如,揭示有於與填隙材料相接的面具有包含特定的氟樹脂的塗膜的接合器(參照專利文獻1)或具有包含低密度聚乙烯或聚丙烯的塗膜的接合器(參照專利文獻2)。另外,揭示一種包含聚乙烯等聚烯烴且將黏著力與拉伸強度調整為規定 的範圍的三面接著防止膠帶(例如專利文獻3)。 As a method of performing double-sided bonding, a method of forming a coating film having low adhesion to the caulk material on the surface of the adapter in contact with the caulk material (the receiving portion of the caulk material) has been studied. For example, an adapter having a coating film containing a specific fluororesin on a surface in contact with a caulking material (refer to Patent Document 1) or an adapter having a coating film containing low-density polyethylene or polypropylene (refer to Patent Document 1) is disclosed. Document 2). In addition, it discloses a polyolefin containing polyethylene and the like and adjusts the adhesive force and tensile strength to the specified The three sides of the range are followed by anti-adhesive tape (for example, patent document 3).

然而,接合器於被搬入施工現場後至對建築物外包裝進行施工為止之間有時被放置於室外。期間,接合器的與填隙材料相接的面容易與填隙材料接著,於對建築物外包裝進行施工時存在產生三面接著的問題。關於專利文獻1及專利文獻2所示的接合器或使用專利文獻3的膠帶而獲得的接合器,亦有同樣的問題。 However, the adapter may be left outdoors after being brought into the construction site until construction of the building exterior is performed.

本發明者等人對於專利文獻1或專利文獻2所示般的現有的接合器放置於室外後容易與填隙材料接著的理由進行了分析及研究,結果詳情雖未明確,但推斷產生以下的現象。 The inventors of the present invention analyzed and studied the reason why the conventional adapter shown in Patent Document 1 or Patent Document 2 is easily bonded to the caulking material after being placed outdoors. As a result, although the details are not clear, it is inferred that the following Phenomenon.
即,認為將接合器放置於室外的期間,於接合器表面的 塗膜附著(飛來)有塵埃或灰塵等污物,藉由室外的光或水分、熱等而使所述污物固著。而且,認為固著的污物成為起點,導致填隙材料容易接著。 That is, it is considered that during the period when the adapter is placed outdoors, the Contamination such as dust or dust adheres (flies) to the coating film, and the contamination is fixed by outdoor light, moisture, heat, or the like. Furthermore, it is considered that the stuck dirt becomes a starting point, and the caulk is easily adhered.
即,為了維持相對於填隙材料的非接著性,有效的是維持使污物難以固著的表面狀態,因此認為有效的是1)降低塗膜表面的帶電性,且2)降低塗膜表面的表面能。而且,本發明者等人對各種材料進行了研究,結果發現,具體而言若1)依據JIS C 2139:2008而測定的體積電阻率為1.0×1017Ω.cm以下,且2)基於依據JIS R 3257:1999而測定的接觸角並根據克爾布勒(Kaelble)-Uy式而算出的表面自由能為36.6mJ/m2以下,則污物難以固著,可維持與填隙材料的非接著性。 That is, in order to maintain non-adhesion to the caulking material, it is effective to maintain a surface state that makes it difficult for dirt to adhere, so it is considered effective to 1) reduce the chargeability of the coating film surface, and 2) reduce the of surface energy. Furthermore, the inventors of the present invention have studied various materials and found that, specifically, if 1) the volume resistivity measured in accordance with JIS C 2139:2008 is 1.0×10 17 Ω. cm or less, and 2) based on the contact angle measured in accordance with JIS R 3257: 1999, the surface free energy calculated according to the Kaelble-Uy formula is 36.6 mJ/m or less, the dirt is difficult to fix, Maintains non-adhesion to gap filler.
進而發現,滿足該些物性的材料中乙烯.乙酸乙烯酯共聚物雖然通常為密封劑或接著用途等中一般使用的材料,但放置於室外時污物特別難以固著於塗膜的表面,可良好地維持與填隙材料的非接著性。本發明是基於此種見解而成者。 It was further found that ethylene in materials satisfying these physical properties. Vinyl acetate copolymers are commonly used materials for sealants and adhesive applications, but when placed outdoors, it is particularly difficult for dirt to adhere to the surface of the coating film, and it can maintain good non-adhesion with caulking materials. The present invention is based on such knowledge.

對於所獲得的被覆金屬板17~被覆金屬板21的相對於填隙材料的非接著性,將於室外的曝露時間變更為1個月,除此以外 利用與所述相同的方法來測定。 In addition to changing the outdoor exposure time to 1 month for the non-adhesion of the obtained coated metal sheets 17 to 21 to the caulking material Measured by the same method as described above.
然後,利用手自被覆金屬板剝離乾燥的填隙材料,將容易地全部剝離者評價為「◎」,將雖存在一部分難以剝離的部分但大部分剝離而於實用方面無問題者評價為「○」。 Then, the dried caulking material was peeled off from the coated metal plate by hand, and those who were easily peeled off completely were rated as "◎", and those that were largely peeled off and had no practical problems although there were some parts that were difficult to peel off were rated as "○" ".
將被覆金屬板17~被覆金屬板21的評價結果示於表4中。 Table 4 shows the evaluation results of the coated metal sheets 17 to 21 .
如表4所示般,可知進而包含爽滑劑時可更長時間維持與填隙材料的非接著性。 As shown in Table 4, it can be seen that when a slip agent is further included, non-adhesion with the caulking material can be maintained for a longer period of time.
本申請案主張基於2018年3月29日提出申請的日本專利特願2018-065011以及2019年2月7日提出申請的日本專利特願2019-020827的優先權。將該申請案說明書及圖式記載的內容全部引用至本申請案說明書中。 This application claims priority based on Japanese Patent Application No. 2018-065011 filed on March 29, 2018 and Japanese Patent Application No. 2019-020827 filed on February 7, 2019. All the content described in this application specification and drawing is incorporated in this application specification.
[產業上之可利用性] [Industrial availability]
根據本發明,可提供一種即便放置於室外後亦維持相對於填隙材料的非接著性的被覆金屬板。此種被覆金屬板可良好地維持相對於填隙材料的非接著性,適合作為可抑制三面接著的接 合器。 According to the present invention, it is possible to provide a coated metal plate that maintains non-adhesion to a caulk even after being placed outdoors. This kind of coated metal plate can maintain good non-adhesion to the gap filler, and is suitable as a joint that can suppress three-sided adhesion. synthesizer.
