【発明の詳細な説明】 ［産業上の利用分野］ 本発明は軽量な発泡外装材とその製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a lightweight foam exterior material and a method for manufacturing the same.
［従来の技術］
外装材としては、従来より陶磁器質のタイルや、その他
の無機質焼結板が用いられている。[Prior Art] Ceramic tiles and other inorganic sintered boards have traditionally been used as exterior materials.
なお、発泡無機質焼結体としては火山ガラス系原料を主
原料とした発泡体（特公昭６３−２８８４７号）、膨張

スラグを主材とした発泡体（特開昭５６−１０９８５７
号、同５６−ＩＨ’８５８号、同５６−１０９８５９号
、同５７−１７４５９号）などが公知である。In addition, the foamed inorganic sintered bodies include foamed bodies mainly made from volcanic glass raw materials (Special Publication No. 1988-28847), expanded tile rock, red clay, expanded clay, clay, china clay, whitebait, fly ash, ferroalloy, etc. Foam as the main material (Tokuko 5
No. 7-30834, No. 57-13408), a foam based on granulated blast furnace slag (Japanese Unexamined Patent Publication No. 56-109857)
No. 56-IH'858, No. 56-109859, No. 57-17459) are known.
［発明が解決しようとする課題］
従来の陶磁器質のタイルや無機質焼結板は重量が大きい
。[Problems to be solved by the invention] Conventional ceramic tiles and inorganic sintered boards are heavy.
また、上記公知の発泡体は吸水性が犬ぎいところから、
耐水性や耐凍害性に不足したり、汚れが浸み込み易く、
落ちにくいなどの問題がある。泡ガラス系のものは、表
面が滑り易いという問題がある。In addition, since the above-mentioned known foams have poor water absorption,
It lacks water resistance and frost resistance, and dirt easily penetrates,
There are problems with it being difficult to fall off. Bubble glass types have a problem of slippery surfaces.
［課題を解決するための手段及び作用］本発明者が種々
研究を行なったところ、粘土４０〜１０重量部、長石６
０−９０重量部、炭化珪素１重量部以下を混合及び成形
し、１２００〜１３００℃で焼成したものは、閉気孔（
独立気孔、クローズドボア）を有した吸水性が殆どゼロ
の軽量体であることを見出だした。[Means and effects for solving the problem] The present inventor conducted various studies and found that 40 to 10 parts by weight of clay, 6 parts by weight of feldspar
0-90 parts by weight of silicon carbide and 1 part by weight or less of silicon carbide are mixed and molded and fired at 1200-1300°C.
It has been discovered that the material is a lightweight body with almost zero water absorption and has independent pores and closed bores.
本発明はかかる知見に基いてなされたものであり、粘土
及び長石を原料とした発泡焼結体であって、気孔が閉気

発明は、粘土４０〜１０重量部、長石６０〜９０重量部
及び炭化珪素１重量部以下を混合及び成形し、１２００
〜１３００℃で焼成して発泡焼結体とすることを特徴と
する発泡外装材の製造方法を要旨とするものである。The present invention has been made based on this knowledge, and its gist is a foamed sintered body made of clay and feldspar as raw materials, and a foamed exterior material having closed pores. The present invention also provides a method of mixing and molding 40 to 10 parts by weight of clay, 60 to 90 parts by weight of feldspar, and 1 part by weight or less of silicon carbide,
The gist of the present invention is a method for producing a foamed exterior material, which is characterized in that it is fired at a temperature of 1300° C. to form a foamed sintered body.
本発明の製造方法において、粘土としては焼成しても発
泡しない非発泡性の粘土が用いられる。In the manufacturing method of the present invention, non-foaming clay that does not foam even when fired is used as the clay.
長石は特に限定されることなく、各種のものを用いるこ
とができる。炭化珪素は例えば粒径１０μｍ以下の微粉
が用いられる。The feldspar is not particularly limited, and various types can be used. For example, fine powder of silicon carbide with a particle size of 10 μm or less is used.
粘土及び長石の配合量は、粘土が４０〜１０重量部、長
石が６０〜９０重量部が適当である。長石の割合がこれ
よりも少ないと、焼結体の気孔以外の部分の緻密さが不
足し、焼結体の吸水率が高くなる。逆に、長石が上記範
囲よりも多いと、焼結温度が低くなり、焼結体の寸法精
度が悪くなる。Appropriate blending amounts of clay and feldspar are 40 to 10 parts by weight for clay and 60 to 90 parts by weight for feldspar. If the proportion of feldspar is less than this, the density of the sintered body other than the pores will be insufficient, and the water absorption rate of the sintered body will be high. On the other hand, if the amount of feldspar is more than the above range, the sintering temperature will be low and the dimensional accuracy of the sintered body will be poor.
即ち、炭化珪素は、１２００〜１３００℃程度で分解し
てガスを発生させ、このガスにより焼結体に気孔が形成
される。焼成温度が１２００℃よりも低いと、素地に十
分な粘性がないため気孔を形成できない。逆に、焼成温
度が１３００℃よりも高いと、焼成素地が低粘性となり
、形成された気孔が会合して粗大気孔が形成されるよう
になり焼成体の強度が低下する。That is, silicon carbide decomposes at about 1200 to 1300°C to generate gas, and this gas forms pores in the sintered body. If the firing temperature is lower than 1200°C, pores cannot be formed because the base material lacks sufficient viscosity. On the other hand, if the firing temperature is higher than 1300° C., the fired base material will have low viscosity, the formed pores will come together to form coarse pores, and the strength of the fired body will decrease.
上記配合及び焼成温度であると、直径が約２０〜２００
μｍ程度の独立気孔を有し、２４時間吸水率のみならず
煮沸吸水率も実質的にゼロである比重２．０〜１．５程
度の軽量体が得られる。With the above formulation and firing temperature, the diameter is approximately 20 to 200 mm.
A lightweight body with a specific gravity of about 2.0 to 1.5 can be obtained, which has independent pores of about μm size and has substantially zero water absorption rate not only in 24-hour water absorption rate but also in boiling water absorption rate.
