防煙垂壁用片材及防煙垂壁Sheet for smoke-proof hanging wall and smoke-proof hanging wall

本發明有關一種可用作防煙垂壁用片材(防煙垂壁之壁構件)之片材及使用該片材之防煙垂壁。The present invention relates to a sheet that can be used as a sheet for a smoke-proof wall (wall member of a smoke-proof wall) and a smoke-proof wall using the sheet.

背景技術 以日本國為首,各國法令(例如,日本國的情況是建築基準法及建築基準法施行令)已規定,需以可妨礙建築物火災時所產生之煙霧及有毒氣體等流動而可順利進行避難及滅火活動之方式來設置排煙設備。因此,辦公大樓、商業施設等之建築物常會設置防煙垂壁等以作為排煙設備及遮煙設備。 Background technique Starting with Japan, the laws and regulations of various countries (for example, in the case of Japan, the Building Standards Act and the Enforcement Order of the Building Standards Act) have stipulated that it is necessary to prevent the flow of smoke and toxic gases generated in the event of a building fire so that evacuation can be carried out smoothly. and fire-fighting activities to set up smoke exhaust equipment. Therefore, buildings such as office buildings and commercial facilities are often equipped with smoke-proof vertical walls as smoke exhaust equipment and smoke-shielding equipment.

為了暫時阻斷火災發生時之煙及有毒氣體等朝走廊及上層樓流動以確保避難所需時間等目的,防煙垂壁通常裝設在建築物之天花板。因此,為了不因防煙垂壁而使視野受阻或損及美觀,玻璃板、玻璃纖維與樹脂之樹脂複合體等被用作防煙垂壁。玻璃纖維與樹脂之樹脂複合體於相較於玻璃板具有不易破裂之優點。舉例來說,專利文獻1揭示了一種包含玻璃纖維織物與硬化樹脂層之透明不燃性片材。 先行技術文獻 專利文獻 In order to temporarily block the flow of smoke and toxic gases to the corridors and upper floors in the event of a fire to ensure the time required for evacuation, the smoke-proof vertical wall is usually installed on the ceiling of the building. Therefore, glass plates, resin composites of glass fiber and resin, etc. are used as smoke-proof walls in order not to block the view or damage the appearance due to the smoke-proof walls. Compared with the glass plate, the resin composite body of glass fiber and resin has the advantage of not being easily broken. For example, Patent Document 1 discloses a transparent non-combustible sheet comprising a glass fiber fabric and a hardened resin layer. Prior art literature patent documents

發明概要 發明欲解決之課題 專利文獻1所揭示之透明不燃性片材具有下述問題:撕裂強度不佳,施工為防煙垂壁時(尤其是施工為張力式防煙垂壁時)容易發生破裂等。另,張力式防煙垂壁係指在2對豎框之間張設片材而形成之垂壁,可舉例如:從天花板垂下設置時,在片材下部側不具有窗擋之防煙垂壁。 Summary of the invention The problem to be solved by the invention The transparent non-combustible sheet disclosed in Patent Document 1 has the following problems: the tear strength is not good, and it is easy to crack when it is constructed as a smoke-proof wall (especially when it is constructed as a tension-type smoke-proof wall). In addition, the tension-type smoke-proof hanging wall refers to the hanging wall formed by stretching a sheet between two pairs of mullions. For example, when hanging from the ceiling, there is no smoke-proof hanging on the lower side of the sheet. wall.

於此,本發明為解決上述問題,主要課題在於提供一種片材及具備該片材之防煙垂壁,該片材具優異撕裂強度、火災時不易變形、不易燃且可適於用作防煙垂壁用片材。 用以解決課題之手段 Here, in order to solve the above problems, the present invention aims to provide a sheet material and a smoke-proof vertical wall with the sheet material. Smoke-proof vertical wall sheet. means to solve problems

為了解決上述問題,本案發明人等經精心研討後得知,要提高撕裂強度,在防煙垂壁用片材中設置熱可塑性樹脂薄膜一事甚為重要。於此,為了提高防煙垂壁用片材之透明性,提高熱可塑性樹脂薄膜之透明性變得重要。然而,為了提高熱可塑性樹脂薄膜之透明性而採用諸如高透明性之聚對苯二甲酸乙二酯薄膜及聚碳酸酯薄膜來作為熱可塑性樹脂薄膜時,因該薄膜相對價昂,若增加熱可塑性樹脂薄膜之層數,防煙垂壁用片材本身之成本也會相對提高。In order to solve the above-mentioned problems, the inventors of the present case found out after careful study that it is very important to provide a thermoplastic resin film in the sheet for smoke-proof vertical walls in order to increase the tear strength. Here, in order to improve the transparency of the sheet for smoke prevention vertical walls, it is important to improve the transparency of the thermoplastic resin film. However, when adopting such as highly transparent polyethylene terephthalate film and polycarbonate film as the thermoplastic resin film in order to improve the transparency of the thermoplastic resin film, because the film is relatively expensive, if the heat is increased The number of layers of the plastic resin film and the cost of the sheet for the smoke-proof vertical wall will also increase relatively.

爰此,本案發明人等發現,若防煙垂壁用片材採用下述層結構且令熱可塑性樹脂薄膜之厚度在特定範圍以上,則可提高片材之撕裂強度,同時因熱可塑性樹脂薄膜僅設1層,即使熱可塑性樹脂薄膜採用相對價昂之薄膜,仍可以相對較低之成本來進行製造;其中該層結構係依序積層有:以浸滲於玻璃纖維布之狀態來包含之硬化性樹脂層/熱可塑性樹脂薄膜/以浸滲於玻璃纖維布之狀態來包含之硬化性樹脂層。Therefore, the inventors of this case found that if the sheet for smoke-proof vertical wall adopts the following layer structure and the thickness of the thermoplastic resin film is above a specific range, the tear strength of the sheet can be improved, and at the same time, due to the thermoplastic resin There is only one layer of film, even if the thermoplastic resin film is relatively expensive, it can still be manufactured at a relatively low cost; the layer structure is stacked in sequence: it is included in the state of being impregnated with glass fiber cloth Curable resin layer/thermoplastic resin film/curable resin layer impregnated with glass fiber cloth.

然而,本案發明人等進行研討後得知,若僅是防煙垂壁用片材採用依序積層有以浸滲於玻璃纖維布之狀態來包含之硬化性樹脂層/熱可塑性樹脂薄膜/以浸滲於玻璃纖維布之狀態來包含之硬化性樹脂層的層結構,且在此同時令熱可塑性樹薄膜之厚度在特定範圍以上,並無法具備在火災時不易變形且不易燃之性質,而無法具備用作防煙垂壁所必須之性能。However, the inventors of the present case have learned after research that if only the sheet for the smoke-proof vertical wall is laminated sequentially with the curable resin layer/thermoplastic resin film/the The layer structure of the curable resin layer impregnated in the state of glass fiber cloth, and at the same time make the thickness of the thermoplastic resin film more than a certain range, and cannot have the properties of being difficult to deform and non-flammable in a fire, and It cannot possess the performance necessary for use as a smoke-proof vertical wall.

於此,本案發明人等透過觀察加熱試驗時有無發生變形來評價防煙垂壁用片材在火災時不易變形之程度。然後,本案發明人等察覺,加熱防煙垂壁用片材時,熱可塑性樹脂薄膜較硬化性樹脂層更易加熱收縮,若熱可塑性樹脂薄膜之厚度過大,則熱可塑性樹脂薄膜之加熱收縮程度因此增大,防煙垂壁用片材整體變得容易發生變形。本案發明人等更進一步持續研討,發現要使防煙垂壁用片材具備撕裂強度優異、火災時不易變形且不易燃之特性,則令防煙垂壁用片材包含「熱可塑性樹脂薄膜」與「積層在該熱可塑性樹脂薄膜之兩面且以浸滲於玻璃纖維布之狀態來包含之硬化性樹脂層」且令熱可塑性樹脂薄膜之厚度及防煙垂壁用片材之質量在特定範圍內一事甚為重要。本發明即是基於上述知識見解並反覆精心研討而完成之發明。Here, the inventors of the present application evaluated whether the sheet for a smoke prevention vertical wall is not easily deformed in a fire by observing whether or not deformation occurs during a heating test. Then, the inventors of this case discovered that when heating the sheet for smoke-proof vertical wall, the thermoplastic resin film is easier to heat shrink than the curable resin layer. If the thickness of the thermoplastic resin film is too large, the degree of heat shrinkage of the thermoplastic resin film is accordingly When the thickness increases, the entire sheet for smoke prevention vertical walls becomes more likely to be deformed. The inventors of this case continued to study further and found that in order to make the sheet for the smoke prevention wall have excellent tear strength, not easily deformed and non-flammable in the event of a fire, the sheet for the smoke prevention wall should contain "thermoplastic resin film" ” and “hardened resin layers laminated on both sides of the thermoplastic resin film and impregnated with glass fiber cloth” and the thickness of the thermoplastic resin film and the quality of the smoke-proof vertical wall sheet are specified. The scope is very important. The present invention is an invention based on the above-mentioned knowledge and insights and repeated careful research.

Results Table 1 shows the results. The sheets of Examples 1 to 4 are sheets in which curable resin layers 4 are laminated on both sides of the thermoplastic resin film 2 in a state impregnated with glass fiber cloth, and the thickness of the aforementioned thermoplastic resin film 2 is 90 ~130μm, and the quality of the aforementioned sheets satisfies 300~450g/m 2 , which have excellent tear strength, are not easily deformed and are not flammable in a fire. In particular, since the thickness of the thermoplastic resin film of the sheets of Examples 1 to 3 is 120 to 130 μm, the tear strength is particularly excellent, and it is not easily deformed in a fire. As mentioned above, the sheets of Examples 1 to 4 fully satisfy the performance required for the sheet for smoke-proof vertical wall, and are suitable for use as the sheet for smoke-proof vertical wall.

另一方面,比較例1之片材因熱可塑性樹脂薄膜2之厚度小於90μm,撕裂強度不佳。On the other hand, the sheet of Comparative Example 1 had poor tear strength because the thickness of the thermoplastic resin film 2 was less than 90 μm.

此外,比較例2之片材因熱可塑性樹脂薄膜2之厚度超過130μm,熱可塑性樹脂薄膜2之熱收縮程度增大,片材整體發生變形,火災時容易變形且易燃。In addition, in the sheet of Comparative Example 2, since the thickness of the thermoplastic resin film 2 exceeds 130 μm, the degree of heat shrinkage of the thermoplastic resin film 2 increases, and the entire sheet is deformed, which is easily deformed and flammable in a fire.
