本発明の段戸珪石含有塗料は、塗装体の耐熱性および断熱性を従来レベル以上に向上し、耐熱性塗料および断熱性塗料として用いることができる。また段戸珪石含有塗料は、高温下における被塗装体の熱劣化を抑制することができる。例えば、段戸珪石含有塗料からなる断熱性塗料は、排気用ダクト（長さ約４ｍ）の内周面に段戸珪石含有塗料を塗装することにより、ダクトの断熱性を高くすることができ、約４６０℃のガスを排気したとき、ダクト表面の温度を１６０℃にすることができ、建屋内の空調コストを約２割削減することができた例がある。また、金属片（例えば、縦１０ｃｍ、横７ｃｍ、厚さ１ｍｍの平板状）に耐熱塗料を塗布し、塗布した裏面からバーナーで加熱した耐熱テストにおいて、加熱前の温度が塗布面、裏面ともに１２℃であったが、２分加熱後に塗布面が２９２℃、裏面が４１８℃（１２６℃の温度差）、３分加熱後に塗布面が３４８℃、裏面が４７１℃（１２３℃の温度差）となった例がある。 The stepped silica-containing paint of the present invention improves the heat resistance and the heat insulation of the coated body to a level higher than the conventional level, and can be used as a heat-resistant paint and a heat-insulating paint. In addition, the stepo silica-containing paint can suppress thermal deterioration of the object to be coated under high temperature. For example, a heat insulating paint made of stepped silica stone-containing paint can enhance the heat insulation of the duct by coating the inner surface of the exhaust duct (about 4 m in length) with step door silica stone-containing paint, When exhausting gas at about 460 ° C., the temperature of the duct surface can be brought to 160 ° C., and there is an example in which the air conditioning cost in the building can be reduced by about 20%. In a heat-resistant test in which a metal piece (for example, a flat plate having a length of 10 cm, a width of 7 cm and a thickness of 1 mm) was applied to a metal piece and heated with a burner from the applied back side, the temperature before heating was 12 After heating for 2 minutes, the coated surface was 292 ° C and the back surface was 418 ° C (temperature difference of 126 ° C). After heating for 3 minutes, the coated surface was 348 ° C and the back surface was 471 ° C (temperature difference of 123 ° C). There are examples.
一方、段戸珪石含有塗料が塗装体の伝熱特性を改質した例として、寒冷地等の薪ストーブの本体と配管（煙道）の表面に段戸珪石含有塗料を塗装することにより、室内を早く暖めると共に、薪ストーブを消しても暖かさが長く持続した例がある。また、ボイラーの釜に段戸珪石含有塗料を塗装することにより、沸騰するまでの立ち上がり時間が短くなると共に、熱の冷めるまでの時間を長くした例がある。 On the other hand, as an example in which the stepped silica-containing paint has improved the heat transfer characteristics of the painted body, the interior of the wood-burning stove body and pipes (flue) in a cold region can be painted indoors by applying the stepdoor silica-stone-containing paint. In some cases, the wood warms quickly, and the warmth lasts for a long time even when the wood stove is turned off. In addition, there is an example in which a boiler pot is coated with a coating containing stepped silica to shorten the rise time before boiling and increase the time until heat is cooled.
以下、実施例を参照して本発明の段戸珪石含有塗料を更に具体的に説明するが，本発明がそれらの実施例に限定されるものではない。
