〔産業上の利用分野〕
本発明は、多孔質セラミックスの如き気孔度の高い断熱
材用接着剤あるいはコーティング剤に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to adhesives or coatings for heat insulating materials with high porosity such as porous ceramics.
断熱剤として気孔度の高いものが有効であることは既に

ング材を塗板しカスをはじめ燃料等の浸透を防止する必
賛かめる。It is already known that materials with high porosity are effective as heat insulating agents. For example, when a high-porosity insulation material is used as a component of a combustion chamber, combustion scum or fuel penetrates into the pores and inhibits the insulation effect. It is essential to prevent the penetration of water.
また、断熱材を例えばエンジンの燃焼室表面に適用する
場合、断熱材をエンジン部材上に接着する心像がある。Also, when applying insulation to the combustion chamber surface of an engine, for example, there is a concept of adhering the insulation onto engine components.

ス糸耐熱接着剤又はコーティング剤である。When drying and baking is performed after coating, or when heating at KJ temperature is repeated, the problem arises that cracks develop due to the uneven thickness of the coating layer or adhesive layer. [Configuration of the Invention] The present invention is a ceramic yarn heat-resistant adhesive or coating agent which has been developed to solve the above-mentioned problem and is made by mixing 3 to 20 mjt% of silicon carbide, silicon nitride or aluminum oxide whiskers.

が知られている。Adhesives or coating agents used in the present invention include:
Various metal phosphates such as potassium silicate, lithium silicate, sodium silicate, aluminum phosphate, magnesium phosphate, etc. are used as industrial binders, and 40s-Zr is used as a hardening agent.
Oxide yarns or non-oxide yarns to which ceramic powder is added, such as oz e 5isN4@81CeAB, are known.

四内である。In addition, the whisker mixed in the adhesive or coating agent of the present invention may be SiC, At, O, or U5isN4, and its inlay is within the range of 3 to 20 int%.
ウィスカー混入針と接着力との相対的関係を第１図に、

示す。Figure 1 shows the relative relationship between whisker-containing needles and adhesive strength.
FIG. 2 shows the relative relationship between the amount of whiskers mixed in and the amount of T-fissures.

株）製の８１ｓＮ４ウイスカー（径α５〜２μｍ１長さ
５０〜３００μｍ）を用い、かつ１５０℃で焼成した場
合のものである。As can be seen from Figure 1, when the amount of whiskers mixed in is 20 layers or more, the adhesive force between the porous heat insulating material and the coating agent or adhesive decreases rapidly, which is undesirable. If the amount is below, the amount of cracks in the coating agent or adhesive film will rapidly increase, which is undesirable. Ceramic E (Kyocera Corporation!1)
11) The whiskers were manufactured by Tateho Chemical Industry (
81sN4 whiskers (diameter α5-2 μm, length 50-300 μm) manufactured by Co., Ltd. were used and were fired at 150°C.

It can be prevented.
