JP 2005-187275 A

  However, since the above-mentioned refractory and heat-resistant concrete can be applied only to new buildings, it must be said that it is unsuitable for improving the heat resistance of existing buildings and the like. Moreover, since it is a concrete to the last, the use will be limited.

  Therefore, it is desirable that heat resistance can be improved even for existing buildings and the like, but there is still no means for realizing this.

  The heat resistance is not limited to a basic structure such as a building, but is also desired for a resin portion attached to a building, for example. Furthermore, it is desirable to avoid as much as possible that resin products around us are easily deformed and dissolved by heat.

  The present invention provides a heat-resistant material capable of solving the above-described problems and a coating material containing the heat-resistant material as a main component.

  (1) In this invention, it was set as the heat resistant material which added the fly ash and / or carbon to the organic material.

  (2) The present invention is characterized in that, in the heat-resistant material according to the above (1), the blending ratio of the fly ash and / or carbon is 10 to 30% by weight.

  (3) The present invention is characterized in that in the heat resistant material according to the above (1) or (2), a metal is further added to the organic material.

  (4) The present invention is characterized in that, in the heat-resistant material as described in (3) above, the mixing ratio of the metals is 5 to 30% by weight.

  (5) The present invention is characterized in that, in the heat-resistant material according to any one of (1) to (4), the organic material is an epoxy resin.

  (6) The present invention is characterized in that in the heat-resistant material according to any one of (3) to (5), the metal is iron oxide or zinc oxide.

  (7) The present invention provides a method for using a heat-resistant material characterized in that the heat-resistant material according to any one of (1) to (6) is used as a paint.

  According to the present invention, it is possible to remarkably improve heat resistance and fire resistance only by, for example, supporting later on a member used in an existing structure, and remarkably enhance versatility as a heat resistant material. be able to. Also, it becomes possible to easily provide a resin product having high heat resistance.

  The heat-resistant material according to this embodiment is obtained by adding fly ash and / or carbon to an organic material.

  In other words, fly ash that is mainly composed of silica and alumina and collects coal ash generated when pulverized coal is burned, or carbon such as graphite and carbon compounds is selectively added to organic materials, for example, organic resins Alternatively, fly ash and carbon such as graphite or carbon compound are added at the same time.

  Fly ash is often used as a concrete admixture, but it has been found that heat resistance and fire resistance can be improved by adding it to organic materials.

  Therefore, this is applied to an organic material widely used in modern society, and, for example, it is used as a heat-resistant plastic, so that versatility is improved and the needs as a heat-resistant product and a fire-resistant product can be met.

  By the way, the blending ratio of the fly ash and / or carbon is preferably 10 to 30% by weight of the entire heat-resistant material.

  With such a blending ratio, it can be cured and molded, or in an uncured state, it can be applied from above the existing material, and versatility can be further enhanced.

  As the organic resin, it is particularly desirable to use an epoxy resin having dimensional stability and water resistance, and high chemical resistance and electrical insulation. By using an epoxy resin, for example, it can be suitably used for a substrate for an electronic component such as a mother board on which an electronic component having a concern about a malfunction due to heat (so-called “thermal runaway”) such as a CPU is mounted.

  Further, metals can be further added to the organic material such as epoxy resin. In this embodiment, metal oxides such as iron oxide or zinc oxide are used as such metals. By adding such metals, heat dissipation can be improved and heat storage can be prevented, so that it can be made a more suitable material for the mother board and other electronic component boards where overheating is likely to be a problem. Moreover, it is suitable also for the cover of the photovoltaic power generation apparatus etc. whose demand has increased in recent years due to environmental problems.

  And as a compounding ratio of metals, it is good to set it as 5 to 30 weight% of the whole. By setting it as this compounding ratio, it has the said heat dissipation, and it does not impair the viscosity or fluidity | liquidity as a resin material, and also a moldability.

  In order to produce the above-mentioned heat-resistant material, when an epoxy resin is used as the organic material, 70 to 90% by weight of the whole is prepared, and 10 to 30% by weight of the fly ash or graphite is contained therein. What is necessary is just to mix. Or what is necessary is just to mix the mixture of a fly ash and graphite into 10 to 30weight% of the whole in the epoxy resin of 70 to 90weight% of the whole. At this time, the blending ratio of fly ash and graphite may be arbitrarily determined. Here, it was set to 5: 5.

  The above-mentioned heat-resistant materials are extremely versatile. For example, the above-mentioned electronic component substrates, heat-resistant plastics that take advantage of the high adhesiveness, toughness, corrosion resistance, etc. of epoxy resins, as well as household goods as fire-resistant plastics. It is possible to use.

  Moreover, as another embodiment of the present invention, the above-mentioned heat-resistant material can be used as a paint. In order to obtain a paint, a predetermined additive or pigment may be added as appropriate. Thus, since it can be used as a coating material, there is no risk of impairing at least the appearance when it is applied, and it is suitable for renovation work and the like. In particular, since the heat-resistant material according to the present embodiment also has rust prevention properties, it is extremely useful as a paint for building materials.

  A wide range of application targets, for example, by applying to the roofs, outer walls, inner walls, and doors of existing buildings and structures, the heat resistance and fire resistance can be significantly improved. Moreover, it can be applied to steel frames, stairs, and even elevator shafts, whether indoors or outdoors. That is, since it can be used as a paint, fire resistance can be imparted to an existing building even later. Therefore, it can be widely applied to ordinary houses, high-rise buildings, and oil tanks.

  Thus, if it is used as a paint, heat resistance and fire resistance can be imparted only by applying from the top of existing building materials, so that the utility value becomes extremely high.

  An experiment as shown in FIG. 1 was performed on the heat-resistant material described above.

  In FIG. 1, 1 is a test piece made of a heat-resistant material according to the present embodiment, 2 is a gas burner, and 3 is a temperature sensor that measures the flame temperature of the gas burner 2. As shown in FIG. 2, the test piece 1 is obtained by applying a heat-resistant paint 11 made of the above-described heat-resistant material to a steel material 10 having a thickness of 3 mm so as to have a film thickness of about 500 μm. The steel material 10 is a normal steel plate having a heat resistant temperature of about 600 ° C.

  And as shown to Fig.1 (a), the flame of the gas burner 2 was injected from one side of the test piece 1 until the temperature sensor 3 became 1000 degreeC.

  As shown in FIG.2 (b), with respect to the temperature of 1000 degreeC, the applied heat-resistant coating material 11 was only burnt and the steel material 10 did not deform | transform and melt | dissolve.

  Thus, it was found that the heat resistance and fire resistance were remarkably improved only by applying the heat resistant paint 11.

  Therefore, by using the heat-resistant paint 11 described above, it is possible to expect sufficient heat resistance and fire resistance for existing buildings and structures.

It is explanatory drawing which shows a heat-resistant experiment outline. It is explanatory drawing of the test piece using the heat resistant material which concerns on this embodiment.
