Description
本発明は、優れた耐熱保護性を有する積層体に関するものである。本発明の積層体は、建築構造物における各種基材を高温から保護する目的で使用することができる。 The present invention relates to a laminate having excellent heat resistance protection. The laminate of the present invention can be used for the purpose of protecting various substrates in a building structure from high temperatures.
建築構造物が火災によって高温に晒された場合には、柱、梁、床、屋根、壁等の各種基材の物理的強度が急激に低下するおそれがある。これに対して、建築構造物の各種基材を耐熱保護材で被覆して耐熱性を高める方法が種々提案されている。 When a building structure is exposed to high temperatures due to a fire, the physical strength of various substrates such as columns, beams, floors, roofs, walls, etc. may be rapidly reduced. On the other hand, various methods have been proposed for improving the heat resistance by coating various substrates of a building structure with a heat resistant protective material.
耐熱保護材としては、例えば、ロックウール、パーライト、バーミュキュライト等の無機質軽量骨材とセメントとを含む材料がよく知られている。しかしながら、かかる材料の耐熱保護材を使用する場合、十分な耐熱性能を得るためには、20〜50mm程度の厚い被膜を施工しなければならない。そのため、施工時に多量の材料を必要とし、作業上の負担が大きい上、乾燥に時間を要するという問題もある。更に、被膜が厚いため、空間の有効利用が妨げられるおそれや、外観上圧迫感を与えるおそれがある。 As a heat-resistant protective material, for example, a material containing inorganic lightweight aggregate such as rock wool, perlite, vermiculite and cement and the like is well known. However, when using the heat resistant protective material of such a material, in order to obtain sufficient heat resistant performance, it is necessary to apply a thick film of about 20 to 50 mm. Therefore, a large amount of material is required at the time of construction, and the burden on the operation is large, and there is also a problem that it takes time for drying. Furthermore, because the film is thick, there is a risk that the effective use of the space may be impeded, and the appearance may be oppressive.
近年、これらの欠点を改良した耐熱保護材として、熱膨張性材料を用いた耐熱保護材が注目されている。熱膨張性材料は、火災時の温度上昇によって熱膨張性材料の被膜が膨張することにより炭化断熱層を形成することができるため、初期段階(施工段階)の被膜を薄膜化することが可能である。 In recent years, a heat-resistant protective material using a thermally expandable material has attracted attention as a heat-resistant protective material in which these drawbacks are improved. The thermally expandable material can form a carbonized heat insulating layer by expanding the film of the thermally expandable material due to the temperature rise at the time of fire, so that it is possible to thin the film of the initial stage (construction stage) is there.
かかる熱膨張性材料としては、例えば、ポリ酢酸ビニル、アクリル樹脂等の結合材と、ポリリン酸アンモニウム等のリン化合物と、多糖類、多価アルコール等の炭化剤と、メラミン、ジシアンジアミド等の含窒素発泡剤とを主要成分とする熱膨張性材料が挙げられる(特許文献1、特許文献2等)。 As such a thermally expandable material, for example, a binder such as polyvinyl acetate and acrylic resin, a phosphorus compound such as ammonium polyphosphate, a carbonizing agent such as polysaccharide and polyhydric alcohol, and nitrogen containing such as melamine and dicyandiamide Examples thereof include thermally expandable materials having a foaming agent as a main component (Patent Document 1, Patent Document 2 and the like).
ところで、高度な耐熱保護性が要求される場合、上記特許文献1、2等に記載の熱膨張性材料では、その厚みを大きくする手段を採用することができる。しかし、上記特許文献1、2等に記載の熱膨張性材料では、厚みに応じた耐熱保護性が得られにくい場合があり、十分な耐熱保護性を満たすには、相当な厚みが必要となる場合がある。 By the way, when a high degree of heat resistance protection is required, a means for increasing the thickness can be adopted for the thermally expandable material described in Patent Documents 1 and 2 and the like. However, in the case of the thermally expandable materials described in Patent Documents 1 and 2, etc., it may be difficult to obtain heat resistant protection according to the thickness, and a considerable thickness is required to satisfy sufficient heat resistant protection. There is a case.
本発明は、このような問題点に鑑みて完成されたものであり、熱膨張性材料を用いた積層体(耐熱保護材)であって、薄膜性、熱膨張性及び耐熱保護性において優れた性能を発揮することができる、新たな積層体を提供することを目的とする。 The present invention has been completed in view of such problems, and is a laminate (heat-resistant protective material) using a thermally expandable material, and is excellent in thin film properties, thermal expansion and heat-resistant protective properties. It aims at providing a new layered product which can exhibit performance.
本発明者は、上記目的を解決するために鋭意検討を重ねた結果、特定の熱膨張層A及び熱膨張層Bが少なくとも積層されている積層体を採用する場合には、上記目的が達成できることを見出し、本発明を完成するに至った。 As a result of intensive studies to solve the above object, the present inventor can achieve the above object when adopting a laminate in which at least a specific thermal expansion layer A and thermal expansion layer B are laminated.
