〔従来の技術及びその問題点〕
従来、内燃機関のピストン、シリンダヘツド等のエンジ
ン部品の断熱材としては、窒化ケイ素、ジルコニア、ム
ライト、チタン酸アルミ等のソリツド状のセラミツクス
が用いられている。
これらのセラミツクス材は強度的には十分強いものであ
るが、熱伝導率が大きいためにエンジンの吸入効率の低
下をきたすという問題があつた。
他方、熱伝導率の小さいセラミツクス材としては、例え
ば発泡セラミツクスあるいはセラミツクス繊維の積層体
等があるが、これらのセラミツクス材は強度が数１０kg
/cm2程度と小さく、燃料燃焼時の爆発圧力には耐えられ
ない。
これらを改良したものとして、金属アルコキシドを原料
とするコーテイング剤を結合剤として無機質繊維材料、
中空体を添加した断熱材があるが、これを製造するには
焼成前の乾燥に長時間を要するという欠点があつた。
〔発明の構成〕 本発明は上記従来技術の欠点を改善するためになされた
ものであつて、 (1)無機質コーテイング剤 (2)無機質コーテイング剤の固形分１００重量部に対し
て、５〜４０重量部のチタン酸カリウム繊維、１０〜５
０重量部の窒化ケイ素ウイスカ及び／又は０〜１５重量
部のグラスバルン 及び (3)更に硬化促進剤として、前記(2)のチタン酸カリウム
繊維、窒化ケイ素ウイスカ、グラスバルンの１〜１０重
量％の酸化カルシウム（CaO） を混合し、乾燥・焼成してなるピストン、シリンダヘツ
ド等の内燃機関のエンジン部品であつて、硬化促進剤と
してCaOを添加することにより乾燥時間の短縮をはかつ
たものである。
本発明において、無機質コーテイング剤としては一般に
市販されているものを使用できる。
実施例１ シリカ、チタニアを主成分とする無機質コーテイング剤
（日本合成ゴム（株）製グラスカＥ１１０１）の固形分
１００重量部に対し、チタン酸カリウム繊維１５重量
部、窒化ケイ素ウイスカー２０重量部、ガラス中空体５
重量部を混合し、混練機で十分に攪拌混練する。この混
練物に対し、0.８重量部の酸化カルシウムを混合し、更
に十分に混練した後、所定の形状の密閉された型内に加
圧しながら注入した。
注入後薬３時間程でスラリーの硬化が始まつたので、内
型を取り出し、蓋をして密閉し、そのまゝの状態で乾燥
せしめた。
この際密閉しないで乾燥した場合、大気に直接触れる部
分とそうでない部分とで乾燥条件が異なるため変形ある
いは割れを生ずる場合がある。
ついで１２時間以上密閉状態で乾燥し、得られた成形体
を１１００℃で３０分間焼成し、断熱材を得た。
該断熱材の熱伝導率は1.５KCal/m.h.℃、圧縮強度５６
０kg/cm2以上であつた。
本発明において、チタン酸カリウム繊維及び窒化ケイ素
ウイスカの添加量が夫々無機質の固形分１００重量部当
