材の軽量化が求められていた。There are two types of stone materials, natural stone materials and artificial stone materials. Natural stone materials may be depleted of resources or may become difficult to obtain in the future. It is a material. In recent years, a large amount of artificial stone materials have been used as building materials, and in addition to strength and durability, designability has been improved, making it easier for designers to express their intentions, and artificial stone materials meet this need.
In other words, natural stones have different original patterns at the time of generation and there are problems in design, but artificial stones have the characteristic that the filler to be blended can be changed freely and the same design can be easily created. ing. Thus, while artificial stone has the advantage of design selectivity, it has the same physical properties as natural stone and is heavy. Therefore, construction and processing at the construction site are not always easy, and it has been required to reduce the weight of the artificial stone material.

た。An artificial stone material laminate in which a lightweight material is used as an inner layer material and a cementitious artificial stone material is used as a surface layer material has been one means of reducing the weight. Therefore, for example, JP-A-6
As disclosed in JP-A-3-261040, lightweight calcium silicate is used as an inner layer material, and by attaching a thin artificial or natural stone material as an outer layer material to the surface thereof with an adhesive, lightness and crack resistance are obtained. There is known a bonding method that improves the above. However, in the case of pasting and joining, the reliability of the adhesive strength is not sufficient, and the number of working steps is increased because it is necessary to procure a stone board in advance. Further, the ordinary stone plate has a defect that air bubbles are likely to be mixed and the denseness is poor.

Japanese Patent Application No. 5-90592 proposes a manufacturing method in which the inner layer material and the surface layer material are molded by a press machine, and then the surface layer material is cured and simultaneously pressure-bonded and integrated. However, in molding with a press machine, although the adhesive strength is reliable, there is a risk of damaging the lightweight material due to the delicate adjustment of the compressive force, bubbles remain, and further improvement in denseness is required.

In addition, a low water content is necessary for improving the compactness. Also, the artificial stone material and the porous material must have sufficient adhesive strength. The air bubbles are reduced when the kneaded raw material of the artificial stone material has high fluidity, but a large amount of water must be added to this. Also, if the water content is too high, the resulting product will lack compactness. The water absorbed from the raw material kneaded material of the artificial stone expels air from the porous material and causes a large amount of bubbles.

According to the conventional method, press working is used only for improving the denseness, and there is no process for simultaneously performing molding and joining.

As a result of various studies on densification of cementitious artificial stone material and lamination integration with porous material, as a result of supplying hydraulic cementitious artificial stone material on the porous material and vibrating it in an atmosphere below atmospheric pressure , Air bubbles are released from the porous material, and then the air bubbles float up and are removed in the kneaded material of the artificial stone material. As a result, degassing of the kneaded raw material of the artificial stone and water absorption of the porous material proceed at the same time. Therefore, it has been found that the raw material kneaded product of the artificial stone material can be densified and the raw material kneaded product of the artificial stone material can be completely adhered even after the hardening by the deep penetration of the cement slurry into the porous material.

A strong composite was obtained, and a laminated body including a surface layer body and an inner layer body was obtained.

るのが好ましい。The present invention will be described in more detail below. The porous material used in the artificial stone material laminate of the present invention is intended to reduce the weight, and does not lose its strength even when laminated on a thin plate. In the product of the present invention, this porous material serves as the inner layer material. Although the material of the porous material is not particularly limited, it is preferably lightweight, and specifically, it is lighter than the specific gravity of concrete of about 2.2. More preferably, the cement slurry of the artificial stone has many voids that can penetrate deep into the inner layer material and has a high water absorption rate. It is preferable that the porosity is 30 to 95%, which is expressed by (true specific gravity-apparent specific gravity) / true specific gravity x 100%. As the cement slurry permeates into the inner layer material, the adhesive strength between the inner layer material and the surface layer material increases. As such a material, a calcium silicate-based material, a gypsum-based material, a cement-based material or the like is preferable. Among them, the calcium silicate-based material is the most excellent in terms of lightness and strength. The inner layer material is preferably reinforced with commonly used reinforcing fibers such as carbon fibers, glass fibers and pulp, or organic fibers such as vinylon, acryl and Kepler.

Further, it is not suitable because it impairs the compactness of the artificial stone material. In addition, as an auxiliary agent added to the artificial stone material in the present invention,
There are surfactants and thickeners that promote fluidization of uncured artificial stone materials, defoaming agents that reduce air bubbles, modifiers that promote hardening, and cement matrix strengthening agents, depending on the purpose. About 1 to 5 kinds can be added.

For example, when a plate-like material is manufactured in the manufacturing process, a mold is fixed on a table-type vibrator via a rubber packing for sealing, and a porous material is placed on the bottom of the mold. A predetermined amount of the kneaded material of the artificial stone material is supplied onto this, and vibration is started in an atmosphere of atmospheric pressure or less. The thickness of the surface layer material and the inner layer material is not particularly limited, but can be arbitrarily selected depending on the intended use of the artificial stone material laminate. Usually, the thickness of each surface layer material is 2 to 30 m

形体が製作できた。結果を表−１に示した。A vacuum pump having a trap with a vacuum gauge and an internal volume of 20 liters was connected to the suction port of the mold. The details of the implementation procedure are as follows. A porous material was placed in the mold, and the raw material kneaded material of the artificial stone material was supplied onto the porous material in an uncured state. The open part at the top of the mold was sealed with a lid-shaped iron plate through a rubber packing for sealing, and the mold was fixed with bolts and nuts. The vacuum pump was operated, and when the pressure reached 60 mmHg or less, the cock of the vacuum trap was opened to reduce the pressure inside the mold. At the same time, the vibrator was activated and vibration started in the vertical direction. Then, after performing the treatment for 3 minutes, the vibration was stopped, the reduced pressure in the mold was leaked, and the pressure was returned to the atmospheric pressure. Then, the molded body was taken out together with the mold and subjected to natural curing for 10 days. Thus, the obtained molded product had a flat upper surface, was not only easy to polish, but was dense, and it was possible to manufacture a laminated molded product having sufficient adhesive strength between the surface layer and the inner layer. The results are shown in Table-1.
