この水硬性無機バインダーの添加量は５〜３５ｗｔ％、
好ましくは５〜２０ｗｔ％である。水硬性無機バインダ
ーを３５＠ｔ％以上添加した場合には強度は向上するが
、コスト高となるため経済的ではない。The amount of this hydraulic inorganic binder added is 5 to 35 wt%,
Preferably it is 5 to 20 wt%. When the hydraulic inorganic binder is added in an amount of 35@t% or more, the strength is improved, but it is not economical because it increases the cost.
なお、必要に応じて水硬性無機バインダーの他に補助粘

ｗｔ％以下、好ましくは２０−ｔ％以下である。これは
配合量が５０ｗｔ％以上になると、配合組成物の酸化ナ
トリウム、酸化カリウムが増加するため、繊維の耐熱温
度が低下するためである。The blending amount of the Briquent molded body into the conventional raw material is 50
It is less than wt%, preferably less than 20-t%. This is because when the blending amount exceeds 50 wt%, the amount of sodium oxide and potassium oxide in the blended composition increases, which lowers the heat resistance temperature of the fiber.
本発明では粘土鉱物を使用するので、粘土鉱物の有する
粘結性により成型し易くなり、かつ無機バインダーを併
用することで、成型体としての強度が保持される。Since clay minerals are used in the present invention, the caking properties of the clay minerals facilitate molding, and the combined use of an inorganic binder maintains the strength of the molded product.
