Methods such as using water glass, Portland cement, and a thermosetting resin have been proposed and implemented. The sintering method can provide a strong sintered body,
It requires a temperature of one thousand and several hundred degrees, requires a great deal of energy, and consumes a great deal of fuel and power. The equipment will also be large. When water glass, Portland cement or the like is used (JP-A-57-88062, JP-A-58-225)
5) In the case of using water glass, it takes a long time to develop water resistance, and in the case of using cement, there is a problem of whitening that white precipitates appear when immersed in water. Also, the strength is significantly deteriorated. Since the artificial stone mainly composed of a thermosetting resin is mainly composed of an organic resin, its fire resistance is limited, and the appearance must be polished and glossy.

I do. There is no restriction on the mixing ratio of the clay, and it is adjusted according to the required color tone and specific gravity. The apparent specific gravity is larger for kaolin alone and decreases with an increase in the ratio of sericite. The apparent specific gravity of the mixture is between 1.77 and 1.06, depending on the influence of other compositions.

It is desirable that the amount be as small as possible in order to reduce the time for subsequent drying, but it increases as the proportion of sericite increases.

The slurry has thixotropy, and after filling in a mold, it can be swung to float and release mixed bubbles. After defoaming, the mixture is air-dried in a static state to reduce the weight by about 10% of the filling amount. Silicone release agents are less effective and it is desirable to use a film such as release paper on the bottom of the mold.

The drying temperature and time are standard and can be changed depending on the thickness of the molded product and the degree of mixing with the clay. In general, rapid drying is not limited to the above description because the drying speed of the surface exceeds the moving speed of the internal evaporation and causes cracks and warpage.

Since the drying is performed at a temperature of about 100 ° C. and the heating is performed at 110 ° C. to 150 ° C., very little energy is consumed. When water glass or the like is used, the amount of energy is small, but it takes a long time for curing and aging, and it takes several tens of days to develop water resistance. In the present invention, the time required for all the steps is 5 to 6 days, and the water resistance is immediately exhibited. Furthermore, by contact with water,
Does not cause the phenomenon of whitening, which looks like white precipitates.

化が見られる。The amount of the resin in the constituent elements is such that it has excellent fire resistance as a minimum amount of preventing cracking and exhibiting water resistance. Despite being water-resistant due to the sandstone-like porosity of the surface, it does not condense to absorb moisture in humid environments. The mixing of the resin liquid, in combination with the aluminum silicate, enhances the development of water resistance, bending strength, and impact resistance. However, increasing the proportion of the resin increases bending strength and the like, but decreases flame resistance. Mixes exceeding 20% of the total volume (except for the water for kneading) will see the formation of smoke when the flame hits the end of the molded product. Similarly, when it reaches 29%, it shows flame resistance on the surface of the product, but carbonization is seen when it reaches the end.
