Abstract
Description
本発明は、熱膨張性ペースト組成物に関する。 The present invention relates to thermally expandable paste compositions.
一般に、建築物等において建築基準法で定められた防火区画等に配管類や電力ケーブルや通信ケーブル等のケーブル類を貫通させる場合、延焼防止等の観点から防火区画等には一定の耐火性能が求められている。そのため、建築物内の配管類・ケーブル類と防火壁等との間には、防火性能を付与した防火用目地材として、液状ポリマーに金属水和物等を配合したパテ状の耐火材が用いられている（例えば、特許文献１）。 In general, when pipes, power cables, communication cables, etc. are passed through a fireproof section of a building, etc., the fireproof section must have a certain level of fireproof performance from the viewpoint of preventing the spread of fire. It has been demanded. For this reason, a putty-like fireproof material made by mixing metal hydrate with a liquid polymer is used as a fireproof joint material with fireproof performance between pipes/cables and firewalls in buildings. (For example, Patent Document 1).
また、鋼材や、コンクリート、木材、合成樹脂等の基材を火災から保護する材料として、火災時の温度上昇によって発泡層を形成する発泡性耐火塗料も知られている（例えば、特許文献２）。ここで、発泡性耐火塗料は、塗料の成分中に、温度上昇により分解して不燃性のガスを発生する成分と、炭素化して多孔質の炭化層を形成する成分を含有しており、不燃性のガスの発生で火災の消火効果を発揮し、炭素化成分による多孔質炭化層の形成により断熱効果を発揮するものである。 In addition, as a material for protecting base materials such as steel, concrete, wood, synthetic resin, etc. from fire, a foaming fire-resistant paint that forms a foam layer when the temperature rises in the event of a fire is known (for example, Patent Document 2). . Here, the foamable fire-resistant paint contains, among the components of the paint, a component that decomposes when temperature rises to generate a noncombustible gas and a component that carbonizes to form a porous carbonized layer. Extinguishing effect of fire is exhibited by the generation of toxic gas, and heat insulating effect is exhibited by forming a porous carbonized layer by the carbonized component.
ところで、発泡性耐火塗料には、結合材として合成樹脂エマルション等の樹脂が２０質量％程度使用されている。このため、発泡性耐火塗料では、粘度が低く、施工時に液垂れが発生するといった課題があった。 By the way, about 20% by mass of a resin such as a synthetic resin emulsion is used as a binder in the foamable fire-resistant paint. For this reason, the foamable fire-resistant paint has a low viscosity, and there is a problem that dripping occurs during application.
本発明は、このような問題点に鑑みなされたもので、十分な熱膨張性と基材への密着性と形状安定性を有し、かつ施工性に優れた熱膨張性ペースト組成物を提供することを目的とするものである。 The present invention has been made in view of such problems, and provides a thermally expandable paste composition that has sufficient thermal expandability, adhesion to a substrate, shape stability, and excellent workability. It is intended to
