2. Description of the Related Art A conventional coating material similar to the present invention, that is, a so-called heat-resistant paint, is a phenolic resin, a silicone resin or a polyamideimide resin and a modified resin thereof, which is used as a vehicle. There has been proposed one in which a frit that melts at a temperature of not less than ° C. to form a film is mixed. The heat-resistant paint using these synthetic resins as a vehicle, when the temperature of the object to be coated rises, generally exceeds 250 to 450 ° C. (about 500 to 600 ° C. at the maximum), the vehicle is burned, and the adhesive force decreases. At the same time, the bonding force between the pigment particles in the coating film is weakened, and the coating film usually becomes discolored or peels off. Further, even in the case where the frit is used, the maximum heat resistance temperature is about 600 ° C. (Japanese Patent Application Laid-Open No. 60-179476, etc.)

In the conventional coating materials, the roles of the vehicle and the pigment or extender, including the above-mentioned heat-resistant paint, are clearly separated. If the temperature exceeds the heat resistance temperature of the vehicle, the vehicle will be deteriorated or decomposed and burnt, and the function as a coating material will be lost. Therefore, the heat resistant temperature of the paint is largely determined by the heat resistant temperature of the vehicle or frit used therein. With a manufacturing method based on the same idea as the conventional one, which depends only on organic substances for its function as a vehicle, it is not expected to produce a coating material that exceeds the existing heat-resistant temperature. Even after the vehicle of the initially formed coating film is decomposed and burned due to an increase in temperature, it is a strong and stable coating film (having a maximum heat-resistant temperature of 900 to 1,000).
It is an object of the present invention to obtain a composition that can be maintained at about (° C.).

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the first invention has a softening or melting temperature of 700 to 900.
The modified frit whose softening or melting temperature was adjusted to about 700 to 1,250 ° C. by adding 10 to 25 parts by weight of silica stone or feldspar powder to 100 parts by weight of the basic frit at 100 ° C. was used as a vehicle / pigment. Liquid sodium metasilicate (Na 2 SiO 3 : SiO 2 27) functioning as a binder with respect to 100 parts by weight of the vehicle / pigment.
~29%, Na 2 O 9~10% , molar ratio: 3.0
3.2) 150-300 parts by weight, 100-250 parts by weight of an oxide of metal or the like as a pigment and 300-400 parts by weight of a solvent to form a stable heat-resistant film in a wide temperature range from normal temperature to high temperature. It is intended to provide a composition of a heat-resistant paint which is characterized in that: In the second invention, silica powder or feldspar powder is added in an amount of 10 to 2 parts to 100 parts by weight of a basic frit having a softening or melting temperature of 700 to 900 ° C.
By adding 5 parts by weight, the softening or melting temperature can be reduced to about 70
The modified frit adjusted to 0 to 1,250 ° C. is used as a vehicle / pigment, 70 parts by weight of the vehicle / pigment, and 30 parts by weight of diboron trioxide (B 2 O 3 ) having a softening or melting temperature of about 350 to 1,500 ° C. Parts from room temperature to about 4
As an organic initial binder for forming a coating film in a temperature region up to 50 ° C., 50 to 90 parts by weight of a silicone alkyd-modified varnish or silicone epoxy-modified varnish and 80 to 200 parts by weight of an oxide such as a metal as a pigment and a solvent Toluene (C 6 H 5 CH 3 ) and xylene [C 6
H 4 (CH 3 ) 2] each comprising 70 to 130 parts by weight,
It is an object of the present invention to provide a heat-resistant paint composition characterized by forming a stable heat-resistant film in a wide temperature range from room temperature to high temperature. As the oxide of the metal, for example, an oxide of at least one metal selected from titanium, chromium, nickel, manganese, magnesium, aluminum, zinc, copper, iron, and silicon is used. A coating material formed by the composition of the heat-resistant paint uses a silicate-based inorganic substance having a high heat resistance and a silicone resin or an alkyd or epoxy-modified resin thereof, as a vehicle for forming an initial coating film.
Even if the vehicle decomposes and burns out, in response to the rise in temperature, a part of the pigment is softened or melted by the high-temperature heat, and a material formula that newly plays the role of the vehicle in the relay system is used. Do. In other words, by using high-temperature heat in reverse, it is possible to form a stable coating film even at high temperatures (rather, only at high temperatures). The details will be described below. The paint formed from the composition of the heat-resistant paint of the first invention described in claim 1 is a water-based paint, and in this water-based paint, the liquid sodium silicate used as the initial binder is from about room temperature to about Although it retains its function as a binder in a temperature range of 1,080 ° C., in a temperature environment exceeding 700 to 800 ° C., its fluidity increases and the stability of the coating film falls. In the present invention, in such a temperature condition,
A modified frit is used as a means for supplementing the deterioration of the function of sodium silicate as a binder. That is, the modified frit softens or melts in a temperature range exceeding about 700 ° C. where the fluidity of the sodium silicate increases and the viscosity decreases, thereby compensating for the decrease in the binder function of the sodium silicate and acting as a vehicle. In a temperature range of not more than ° C., it functions as a part of the pigment.
By the way, basic frit (softening point: 700-900 ° C)
When 10 parts by weight of silica powder is added to 100 parts by weight, the softening point is about 900 to 1,100 ° C.
When 5 parts by weight are added, the softening point is approximately 1,100 to 1,25.
The softening point varies considerably depending on the mixing ratio of the silica powder so that the temperature becomes 0 ° C., but 10 to 25 parts by weight of the silica stone or feldspar powder is added to 100 parts by weight of the basic frit, This is because, as a result of the experiment, the ratio of sodium metasilicate is appropriate for obtaining a stable coating film by compensating for a decrease in viscosity and an increase in fluidity in a temperature range of about 700 to 1,080 ° C. When the proportion of silica powder or feldspar powder is 10 parts by weight or less, the viscosity is too low, and when it exceeds 25 parts by weight, the viscosity is too high to form a stable coating film, making it difficult. Further, the paint formed by the composition of the heat-resistant paint according to the second invention described in claim 2 is:
An oil-based paint, in which a silicone alkyd-modified varnish or a silicone epoxy-modified varnish is used as an organic initial binder that forms a coating film in a temperature range from room temperature to about 450 ° C. In the second invention, the modified frit described in claim 1 (softening or melting temperature is 700 to 1,250) is used as a vehicle and a pigment, since these resins are burned when the temperature exceeds approximately 450 ° C. in addition to ° C.), by softening or melting temperature to use diboron trioxide of about 350~1,500 ℃ (B 2 O 3) , 45
In a temperature range exceeding 0 ° C., a stable coating film is obtained even after the organic initial binder is burned out. That is, in the temperature range from normal temperature to about 450 ° C., a silicone alkyd-modified varnish or a silicone epoxy-modified varnish is used as an initial binder at about 350 to 1,500 ° C.
In the temperature range, diboron trioxide (B 2 O 3 )
In the temperature range of about 700 to 1,250 ° C., the denatured frit # 1121-HS10 and # 3907-HS20 each function as a relay and centrally as a vehicle, so that, as a whole, in the temperature range from room temperature to about 900 ° C. A stable coating film is obtained.
