との熱膨張が合わない事が原因の一つでもある。 Among these, metals have low infrared emissivity and are unsuitable as radiators. Furthermore, glass has high transmittance for wavelengths of 5 μm or less and low emissivity. Further, although ceramic coating is applied to improve the radiation characteristics of glass, it is easily peeled off by heat shock. One of the reasons for this is that the ceramic coating is thick and its thermal expansion does not match that of the glass.

できる。Description of Examples Examples of the present invention will be described below. Far-infrared radiating materials include polyborosiloxane resin (organic polyborosiloxane), Zr, Ti, Si, Fe, Cu,
It is a heat-cured product made by dispersing and mixing at least one metal oxide such as Mn, Ni, etc., or one or more metal oxides such as La, Ce, Pr, Nd, etc. Most of the solvent in organic polyborosiloxane evaporates at 300°C, and the remainder consists of a main chain consisting of Si, B, and O, and a phenyl group bonded to this main chain as a side chain. When heated further to 600°C, the phenyl group decomposes, leaving only porous polyborosiloxane composed of Si, B, and O. Figure 1 shows the weight change due to the thermobalance. By dispersing and mixing fillers into organic polyborosiloxane with these characteristics,
By applying it to a substrate and curing it by heating, it is possible to obtain various functional films. A far-infrared radiating material can be obtained by adding a metal oxide or a rare earth element oxide to this organic polyborosiloxane and curing it by heating. Metal oxides include Zr, Fe, Cu, and Mn in particular.
Ce is particularly suitable as the rare earth element oxide. The particle size of these oxides is 0.1-2μ
m is desirable. Figure 2 shows the wavelength-emissivity characteristics at 500°C when a coating of this far-infrared radiating material was formed on a stainless steel substrate. In Figure 2, 1 is a standard black body, 2 is an organic polyborosiloxane with oxides of Fe, Cu, and Mn added, 3 is an organic polyborosiloxane with oxides of Zr and Ce added, and 4 is a stencil. This is a characteristic when only It is clear from this that stainless steel No. 4 has a low emissivity overall. In addition, in case 2, the emissivity is relatively high and flat over the entire measured wavelength range, and in case 3, the emissivity changes greatly after about 7 μm, and the emissivity changes with respect to the wavelength. It can be seen that has selectivity. In any case, it is clear that both 2 and 3 have a higher emissivity of far infrared rays than stainless steel. It was also confirmed that this characteristic hardly changes if the film thickness of the radiant material is 5 to 50 μm. This shows that it is possible to freely choose between a thin film and a relatively thick film depending on the usage environment and purpose. The performance of this radiant material as a coating film is excellent in heat resistance, thermal shock resistance, acid resistance, and alkali resistance, and it can withstand thermal shock from 800℃ on metal to rapid cooling into water. The above-mentioned radiant material is coated on a transparent substrate to form a far-infrared radiator, and in this example, it was coated on the surface of a cylindrical heat-resistant glass of a gas stove. FIG. 3 shows a cross-sectional view of it. Fourth
The figure is a partial cross-sectional view of the combustion part when the radiator of FIG. 3 is installed in an actual machine. The film thickness of the radiant material is approximately 5μ.
When set to m, it becomes transparent and exhibits a faint red color during gas combustion. The temperature of the glass during combustion reaches approximately 500°C, but as shown in Figure 2, far-infrared rays are radiated from the glass surface at a high rate, making it highly efficient in terms of energy and providing comfortable heating. It can be carried out.

A green pigment consisting of the element Ni was added and similarly applied to the surface of heat-resistant glass. As a result, the radiating part of the stove usually turns green, but the coloring can be changed as desired, and it is possible to form far-infrared radiators that visually have various colors. At this time as well, a thin film is formed, giving it a faint red color during combustion.
