問題があつた。 This type of molding method has the advantage of being able to continuously produce a large amount of molded products, but the uncured molded products immediately after molding are soft and easily deformed.
There was a problem in that it was difficult to provide a colored layer on the surface or to provide an uneven pattern on the surface.

となるといつた問題があつた。 In addition, when molding porous inorganic molded products by extrusion molding, foamed plastic beads are mixed into the inorganic kneaded material and extruded. However, when such a kneaded material is extruded, the internal pressure Due to this, a so-called springback phenomenon occurs in which the foamed plastic beads protrude from the surface of the molded product immediately after being discharged, resulting in unevenness on the surface of the molded product, which requires a separate process to smooth out the uneven surface. There was a problem.

とするものである。 The present invention was made in view of the above-mentioned problems, with the object of providing a method for coloring an inorganic extrusion molded product, in which the surface of an extrusion molded product can be easily colored, and the surface condition can also be arbitrarily shaped. The inorganic kneaded material is extruded using an extrusion molding device, and immediately after the extrusion molding, a powder (veneer) made of a mixture of cement, pigment, silica, and short fibers is sprinkled on the surface of the molded product, and then pressed with a roller. After shaping, water is sprayed and then emulsion coating is applied.
以下、この発明を実施例により説明する。 This invention will be explained below with reference to Examples.

を施すことにより構成されている。 FIG. 1 is a schematic cross-sectional view of an apparatus for carrying out the present invention.
An inorganic kneaded material 2 made by kneading fine aggregate, reinforcing fibers, and water is extruded, and immediately after the extrusion, a colored powder (veneer) made of a mixture of cement, pigment, silica, and short fibers is placed on the surface of the molded product 2A. ) 3,
After being pressed and shaped by rollers 4 on the downwardly extending portion 7 of the die land, the powder 3 supplies moisture 5 necessary for curing, and then an emulsion is applied to the surface of the compact to prevent efflorescence during the curing process. Painting 6
It is constructed by applying the following.
尚、エマルジヨン塗装６を施した後は、成形品
は通常の養生工程へと送られ硬化される。 After applying the emulsion coating 6, the molded product is sent to a normal curing process and hardened.
又、上記実施例におけるローラ４は成形体２Ａ
表面に散布された粉末体３表面に例えば木目模様

で圧着されるものであつて、この圧着により成形
体２Ａが変形してしまうようなことはない。 Moreover, the roller 4 in the above embodiment is the molded body 2A.
The powder body 3 that has been sprinkled on the surface is pressed with the necessary pressing force in order to give an uneven pattern such as a wood grain pattern to the surface of the powder body 3, and the molded body 2A is not deformed by this pressure bonding. There isn't.
又、押出成形品２Ａを多孔質とする場合は、無
機質混練材料２中に発泡プラスチツクビーズ例え
ば発泡スチレンビーズなどが混入される。 Further, when the extrusion molded product 2A is made porous, foamed plastic beads such as foamed styrene beads are mixed into the inorganic kneaded material 2.

３によりカバーされ、外部に表出するのが防止さ
れる。 In this case, immediately after the inorganic kneaded material 2 is extruded from the extruder 1, expanded styrene beads protrude from the surface of the molded product due to the so-called springback phenomenon, but these are covered by the colored powder material 3 that is sprinkled and supplied to the outside. is prevented from appearing.

まれる水分によつても行われるから、上記工程に
おける水分供給は無機質混練物から着色粉末３へ

る。 Further, since the colored powder 3 is hardened by the water contained in the inorganic kneaded material, the amount of water supplied in the above step is only the amount that is insufficient due to the water transferred from the inorganic kneaded material to the colored powder 3. Ru.

る。 As described above, when coloring an extrusion molded product, this invention sprays and supplies the coloring material while the internal pressure of the molded product is sufficiently high immediately after extrusion molding, and shapes the surface with a shaping roller. Since the molded product is completely finished, the colored layer can be provided without deforming the molded product, and since the roller is pressed onto the colored powder material before it is wetted, the powder material also acts as a mold release agent. It is also possible to effectively prevent the inorganic kneaded material from adhering to the roller.

する。 Furthermore, even when manufacturing porous inorganic extrusion molded products, the colored powder layer covers the irregularities on the surface of the molded product caused by the springback phenomenon, and there is no need for any correction or shaping equipment. This has the effect of allowing for the abbreviation of .
