が容易でないため段差の解消は困難である。The calcium silicate compact is generally supplied to the market as a plate-like material having a length of 3 m × width 1 m × thickness 2-4 cm. When an industrial die is to be manufactured from a plate-shaped material, it is used as a block in which a plurality of these are laminated. When several block-shaped calcium silicate compacts are bonded using a conventional adhesive to produce a block-shaped calcium silicate compact, the cutting will be different due to the difference in machinability between the adhesive and the calcium silicate compact. At that time, the adhesive surface pops out of the plane and a step is generated. Even if sandpaper scouring is performed using sandpaper for this repair, the calcium silicate compact is easy to sandpaper, and the adhesive part is hard and sandpaper is not easy to erasure, so it is difficult to eliminate the step. is there.

At this time, the calcium silicate portion has extremely good machinability, but the portion using the conventional repairing agent has high hardness and extremely poor machinability, and a difference in machinability occurs between the joining surfaces of the two. In order to prevent the step from being generated, the control of cutting becomes complicated and the production efficiency of the process is lowered.

い。If the amount added is less than 15 parts by weight, the hardness will be high, and when used as a repair agent, a step will occur due to the difference in machinability at the joint surface, and when used as an adhesive, the adhesive surface will pop out of the plane during grinding and a step will occur. Occurs. In addition, the workability during cutting is poor, the blade is worn, and the dimensional accuracy during cutting is poor. If the amount added exceeds 65 parts by weight, the hardness of the composition of the polybutadiene acrylonitrile copolymer and the resin will be low, and the wear of the blade will be reduced, but since this composition exhibits a rubber-like shape, the composition part after grinding is processed. Becomes concave, and it becomes easy to grind only the composition portion when sandpaper is applied. Therefore, the finish becomes poor and it cannot be used for an industrial mold or an industrial mold material that requires dimensional accuracy.

From the viewpoint of stability of viscosity, powder of silica stone or limestone having a small oil absorption amount is preferable.

The above is preferable.

る。以下に本発明を実施例により説明する。The filler is used not only for adjusting the viscosity of the above composition but also for reducing the shrinkage factor during curing. The amount of the filler added is 210 to 250 parts by weight in the case of the repair agent and 180 to 220 parts by weight in the case of the adhesive, with respect to 100 parts by weight of the resin as the main component. When the amount of the filler added is less than 180 parts by weight, the viscosity of the composition becomes low, a so-called sagging phenomenon occurs, it is difficult to add it to the adhesive surface, and the shrinkage ratio upon curing increases. On the other hand, when the amount of the filler added exceeds 250 parts by weight, the shrinkage rate at the time of curing becomes low, but the viscosity of the composition becomes high and the assembling work becomes difficult. Therefore, the proper addition amount of the filler is 180 to 250 parts by weight as shown in FIG. The present invention will be described below with reference to examples.
