Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple method for producing resin concrete, which is a new material for machine tool structural materials.

[0002]

2. Description of the Related Art In the conventional manufacturing process of resin concrete, a method of kneading an aggregate and a binder in an agitator and injecting them into a mold is generally used as in the case of manufacturing cement concrete. In order to increase the rigidity of resin concrete, the first step is to refill the aggregate with rock, sand, alumina,
Fill with aggregate such as zirconia, silicon carbide, silicon nitride,
After that, there is already a manufacturing method in which a binder such as an epoxy resin or a phenol resin is filled.

[0003]

The application of resin concrete has recently been studied as a new material having thermal and mechanical properties greatly different from those of conventional materials because of the high precision of machine tools. It is a material. As the manufacturing process, there is a method similar to the former method for manufacturing cement concrete, as described above. However, in this case, it is necessary to knead the aggregate and the binder, move from the stirrer to the mold for kneading, inject the paste resin concrete into the mold, and clean each equipment used. It took time and effort.

In the latter case of the conventional manufacturing process, in which the aggregate is first filled and then the binder is filled, epoxy resin or phenol resin is bonded to the voids between the already filled aggregates. When the material is filled, air is entrained, the binding material does not penetrate well into the contact area between the aggregates, and the binding material is unevenly filled, resulting in an unbonded area of about 20%, resulting in rigidity and strength. Had a drawback that it significantly decreased.

In view of the above points, the present invention intends to provide a simple method for producing resin concrete which can significantly reduce the time and labor required for producing the resin concrete and can further enhance the rigidity and strength. It is a thing.

[0006]

In order to solve the above problems, the method of the present invention uses rock, sand, alumina, zirconia, silicon carbide, silicon nitride or the like as an aggregate, and an epoxy resin,
In resin concrete manufactured using phenolic resin as a binder, a low viscosity liquid binder is dropped into a mold with good sealing performance, and the aggregate is finer than coarse aggregate depending on the particle size. The aggregate is classified into several types, and the aggregate is finer than the coarse aggregate and is sequentially filled into the mold while vibrating, and the aggregate that is filled later is excited and filled with the aggregate that is filled first. After being filled, the voids between the previously-filled aggregates and the binder-filling portion between the previously-filled aggregates are filled while vibrating, and the aggregates are sequentially filled into finer aggregates than coarse aggregates. Further, the liquid level of the binder gradually rises, and at the same time when the final filling of the aggregate is completed, the upper surface of the filled aggregate and the liquid level of the liquid binder are coincident with each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 are views showing an embodiment of a manufacturing process according to the method of the present invention. table,
2 is a filling mold fixed on the vibration table 1 with good airtightness, 3 is coarse aggregate, 4 is medium aggregate, 5 is fine aggregate, and 6 is mold 2
A viscous motor of the vibrating table 1 is a binder of a liquid having a low viscosity such as an epoxy resin or a phenol resin dropped therein.

Next, the manufacturing process of the present invention will be described with reference to the drawings. On the other hand, the filling mold 2 having good airtightness is mounted and fixed on the vibration table 1 while the filling rock, sand, alumina,
Aggregates such as zirconia, silicon carbide, and silicon nitride are classified into coarse aggregate 3, medium aggregate 4, fine aggregate 5, and the like, depending on the particle size, into several types of aggregates finer than coarse aggregates. Then, the binder 6 is dropped into the mold 2 by an appropriate filling amount, and the coarse aggregate 3 is first filled into the mold 2 containing the binder 6 while vibrating (shown in FIG. 1). . Next, the voids between the filled coarse aggregates 3 and the binder filling portions between the coarse aggregates 3 are filled with the medium aggregate 4 while vibrating (shown in FIG. 2). Finally, the voids between the intermediate aggregates 4 and the binder filling portions between the intermediate aggregates 4 are filled with the fine aggregates 5 while vibrating (shown in FIG. 3).

While filling the coarse aggregate 3 with the medium aggregate 4 and the medium aggregate 4 with the fine aggregate 6, the liquid level of the binder 6 gradually rises and the last aggregate is filled. Simultaneously with the end, the upper surface of the filled aggregate and the liquid surface of the binding material 6 coincide with each other.

[0010]

According to the method of the present invention, after the binder is filled in the mold, the aggregates having a larger particle size are sequentially loaded while vibrating the aggregates with a smaller particle size. It penetrates well into the contact area between materials and no unbonded area occurs. Therefore, rigidity and strength are enhanced.

Further, since the aggregate is filled while vibrating in the mold, as in the conventional method, the aggregate and the binder are kneaded during the production of resin concrete, and the moving from the agitator to the mold for kneading, This is a useful invention because the operations such as injecting the pasty resin concrete into the mold and cleaning each equipment used are omitted, and the resin concrete can be manufactured very easily.
