に関するものである。Detailed Description of the Invention (Industrial Application Field) The present invention is directed to pitch-based carbon fiber (hereinafter abbreviated as pitch-based CF) alone or to pitch-based CF with carbon black,
This relates to a carbon fiber insulation material obtained by dispersing and mixing a mixture obtained by mixing at least one type of heat-resistant filler selected from Gratubite, etc. with a foamable resin, and heating and foaming the mixture, which is an inexpensive and simple method. The present invention relates to a heat insulating material that can be easily manufactured, has a wide range of bulk densities, and has a complex shape, and can be used in a wide range of applications in an inert atmosphere.

Carbon fiber insulation materials are widely used in many furnaces used at temperatures above 000°C. Such carbon fiber heat insulating materials are produced in two ways depending on the required heat insulating properties, operating temperature, atmosphere, shape, etc. First, most of them are made from felt, impregnated with a resin with a high carbonization rate such as phenol resin, formed into the desired shape such as a flat plate or cylinder, and then fired at around 2000℃. . The heat insulating material obtained in this way has the advantages of having excellent heat insulating properties, being able to raise and lower the temperature in a short time, being lightweight, and being easy to process. One of the major obstacles to expanding the demand for carbon fiber insulation is that it occupies a large proportion of the cost and is consequently expensive.

．． Insulating materials having a wide range of bulk densities from about 2 to 0.6 gr/cm3 can be manufactured, and materials of various shapes can be manufactured relatively easily.

を受ける。However, carbon fiber milled or chopped fibers can be produced by wet or dry methods of impregnation or mixing, but because they are relatively bulky, they have to be filled into a mold, or carbon fibers with a density higher than the bulk density of the mixture are required. To make this, it is necessary to pressurize it in some way after filling it. Particularly in the case of the dry method, filling is time-consuming and there are limits to the bulk density of the material that is desired to be produced.

ス１〜アンプの要因ともなっている。In order to avoid the above-mentioned problems, it is effective to reduce the apparent density of the mixture of carbon fiber and resin by a wet method and fill it into a mold, and in fact, many carbon fibers are commercially produced using this method. However, even with this method, the solvent in the resin must be distilled off under reduced pressure after filling, which increases the number of steps and becomes a factor in the cost of 1~amp.

を組合せることも可能であり且つ有効である。The pisoti-based CF used in the present invention is a relatively inexpensive general-purpose type, and may be produced from either coal-based or petroleum-based pitch. The shape of the fibers can be used without any particular restriction, but milled or chopped fibers are preferred because as the bulk density of the fibers increases, the mixture with the resin becomes bulky and difficult to fill. Depending on the bulk density or shape of the intended heat insulating material, milled fibers (those with a thread length of about 11 m or less are referred to as milled here) or chopped fibers (those with a thread length of about 1 mm or more) are used. All you have to do is make a selection. In addition, considering strength, heat insulation properties, etc., pitch-based CF of each yarn length is

合である。The foamable resin used in the present invention has good foaming properties, and has a foaming property of about 10
Powder or liquid types can be used as long as they have a relatively high carbonization rate when fired at a high temperature of 00 to 200°C.Pitch-based CF and filler can be used depending on the bulk density, shape, etc. of the intended insulation material. It can be selected depending on the shape, amount, etc. Examples include phenol resin, PSP resin, bismaleid resin, petroleum resin, and pitch. In fact, powder-type foamable resins that use novolasoc-type phenolic resin and abbisisobutyronidonyl (AIBN) as a foaming agent are commercially available and common, but the foam molding heating temperature and foaming agent As long as the decomposition temperature is selected and combined, resins other than phenol can be used as the base material. On the other hand, liquid type foamable resins, such as those using fluorine-based foaming agents such as acid-curable water-soluble resols, have advantages such as easy impregnation with pitch-based CF, easy filling workability, and low-temperature foaming. This is advantageous for the purpose of the present invention.

ある。The blending ratio of pitch-based CF and other heat-resistant fillers and foamable resin has a large effect on foamability depending on the shape, bulk density, etc. of the pitch-based CF and other heat-resistant fillers used.
Also, considering the dimensional stability of the foamed molded product after firing, it cannot be absolutely defined, but the weight ratio is generally 30:70 to 7.
