Description
また、高温で使用される部材の接着剤として、セラミック粉末と、水ガラス、リン酸アルミニウム、シリカゾルあるいはアルミナゾルといった脱水硬化性無機バインダとを混合し、ペースト状とした無機接着剤が市販されている（例えば、東亜合成化学社製「アロンＤ」）。この無機接着剤においては、水ガラス等の脱水硬化性無機バインダが真の接着成分であり、乾燥して被接着物に接着すると共にセラミック粉末相互も接着させて一体の硬化接着層を形成する。セラミック粉末は水ガラス等の脱水硬化性無機バインダが脱水により収縮するので、その影響を小さくする機能と被接着物と接着層との熱膨張係数の差を緩和する機能を有する。 Further, as an adhesive for a member used at a high temperature, a paste-like inorganic adhesive obtained by mixing ceramic powder with a dehydration-curable inorganic binder such as water glass, aluminum phosphate, silica sol or alumina sol is commercially available. (For example, "Aron D" manufactured by Toa Synthetic Chemical Co., Ltd.). In this inorganic adhesive, a dehydration-curable inorganic binder such as water glass is a true adhesive component, and it dries and adheres to an object to be adhered, and ceramic powders also adhere to each other to form an integral cured adhesive layer. Since the dehydration-curable inorganic binder such as water glass shrinks due to dehydration, the ceramic powder has a function of reducing the influence thereof and a function of alleviating the difference in the coefficient of thermal expansion between the adherend and the adhesive layer.
このようなガラス粉末の溶融固化体よりなるシール層は、シール層と外枠との熱膨張係数差を緩和する成分を含んでいることが好ましく、このような熱膨張緩和材を含有させることでシール作業の際の加熱硬化処理の降温時や、耐熱エアフィルタの使用時の昇温、冷却使用中の温度変動などにより、シール層にクラックが発生することを防止することができる。 The seal layer made of such a melt-solidified body of glass powder preferably contains a component that alleviates the difference in the coefficient of thermal expansion between the seal layer and the outer frame. It is possible to prevent cracks from occurring in the seal layer due to the temperature decrease of the heat curing treatment during the sealing operation, the temperature rise when using the heat-resistant air filter, and the temperature fluctuation during cooling.
