となることがあった。When a rubber roll is used in a winding step such as a heat treatment step of a material to be treated such as a soft non-ferrous metal plate, the rubber roll surface hardens during use and cracks due to poor heat resistance. Cracks occur, deteriorating the surface properties of the material to be treated and lowering the commercial value. In addition, abrasion resistance also decreases because the rubber roll surface is hardened. The heat-resistant elastic roll disclosed in Japanese Utility Model Laid-Open Publication No. 52-49377 uses paper or felt made of only aramid fiber as a disc material, and does not have the above-mentioned roll surface particles attached thereto. There is a problem that the workability in the polishing process and the smoothness of the roll surface due to image sticking are deteriorated. Further, the disk roll disclosed in JP-A-64-46571 has no problem in heat resistance, but sometimes causes a problem of adhesion of the roll surface particles to the material to be processed.
【０００４】従って、本発明の目的は、耐熱性及び耐摩

性の良い耐熱ロールを提供することにある。Accordingly, an object of the present invention is to provide a heat-resistant roll which has excellent heat resistance and abrasion resistance and has good surface smoothness without adhesion of roll surface particles.

The present invention relates to a heat-resistant roll characterized in that a shaped article mainly contains aramid fiber and amorphous silica.

を有している。BEST MODE FOR CARRYING OUT THE INVENTION Aramid fiber, which is a main component of a thin plate-shaped molded product which is a disk material constituting a heat-resistant roll of the present invention, has excellent dimensional stability even in a high temperature range where rubber rolls cannot cope. The temperature is as high as 500 ° C. Further, it has much higher strength than other organic fibers, has a long fiber length, and has physicochemical properties enough to include amorphous silica because it is fibrillated. Further, aramid fiber has a characteristic that it does not generate powder due to breakage or the like because it has flexibility that inorganic fiber does not have.

徴を有している。[0007] Amorphous silica, which is another main component of the thin plate-like molded product, has excellent heat resistance even at a high temperature range of about 1000 ° C, and has a very chemically active surface. Therefore, it has the property of being easily included. Moreover, since it is a thermally poor conductor, it has a characteristic of exhibiting excellent heat insulating properties.

めに好ましくない。The mixing ratio of aramid fibers is preferably 40 to 80% by weight. 40% by weight of aramid fiber
If it is less than 1, when formed into a thin plate by a papermaking method, the strength of the molded product is significantly reduced, handleability is deteriorated, and when processing into a heat-resistant roll, it becomes impossible to include amorphous silica, and the roll surface It is not preferable because the scattering property of the particles increases. Further, the mixing ratio of the aramid fiber is 80.
If the weight percent is exceeded, similarly when processing into a heat-resistant roll,
It is not preferable because molding into a heat-resistant roll becomes difficult, and the ratio of amorphous silica relatively decreases, thereby reducing abrasion resistance.

熱性を付与する働きをもつ。Aramid fibers have excellent dimensional stability even in a high temperature range, and can impart excellent heat resistance even when formed into a heat-resistant roll. In addition, since the fiber length is long and fibrillation is progressing, it has a function of sufficiently incorporating amorphous silica and suppressing the scattering property of the roll surface particles. No adhesion. Also,
Amorphous silica has a very active surface chemically and therefore has a property of being easily included in aramid fibers.
Further, it has high heat resistance, and has a function of imparting wear resistance to a heat-resistant roll as a filler, and imparting excellent heat insulating properties by being a thermally defective conductor.
