No. 16785), all of which are patented. As described above, the improvement of the resinoid rotary grindstone has been studied so far so as to enhance the grinding and cutting efficiency and prevent the burn.

<Problems to be Solved by the Invention> By the way, in the work of grinding and cutting a metal or the like using a resinoid rotary grindstone, burning due to frictional heat of the resinoid rotary grindstone, burning of a work material surface treating agent or coating agent, and further An unpleasant odor generated due to burning of the work material itself, and oil and metal odors peculiar to the work place where such a grinding work is performed, so that it cannot be said to be a comfortable working environment. In order to improve this point, a rubber grindstone in which a fragrance is kneaded into rubber is found in JP-A-56-107883, but in a resinoid grindstone, an example of an additive for removing odor can be seen. To some extent (Japanese Patent Publication No. 56-42431, Japanese Patent Publication No. 61-79573),
Aggressive perfume addition does not seem to be commonly adopted due to premature dissipation of perfume.

<Means for Solving Problems> The present invention is intended to solve such problems with respect to the working environment by a method of adding a special fragrance to a resinoid rotary grindstone.

Therefore, abrasive grains, a filler, a method for producing a perfume-containing grindstone in which the composition of a resinoid rotary grindstone consisting of a resin binder holds the perfume in a state in which it is difficult to dissipate, that is, the abrasive grain,
A perfume characterized by mixing a mixture of a filler and a resin binder with a perfume held in an organic or inorganic clathrate compound (hereinafter referred to as clathrate) and kneading, molding and firing. We have developed a method for manufacturing the whetstone.

To hold the clathrate in the composition of the rotating whetstone as used herein means to mix, impregnate, and carry (adhesion, adsorption, yielding) the clathrate to any or all of abrasive grains, fillers, and resin binders. It means to hold it by physical means.

To specifically describe the physical means, "mixing" is simply mixing the inclusion perfume with any of the abrasive grains, fillers, resin binders, or all blends. "Impregnation"
Is to impregnate any one of the abrasive grains, the filler, the resin binder, or the inclusion fragrance in liquid form, and when the resinoid grindstone after molding is subjected to the waxy impregnation treatment described above, It is included in the waxy substance and treated with this waxy substance. "Supporting" is the inclusion of a clathrate on the abrasive grains and fillers that are the raw materials for resinoid grindstones.
Physically integrated by adsorption, sorption, etc., and not only for obtaining the stability of the fragrance in the product, but also for making it possible to stably mix the fragrance during preparation of the raw materials.

The inclusion clever is a preferable means in terms of long-term stability and thermal stability of the flavor holding. The inclusion compound is
As is well known, it is a compound having a structure in which one molecule has a tunnel type, a layered form, or a three-dimensional network structure, and the other molecule enters the gap. It is known that organic substances and inorganic substances exist in those having an inclusion lattice. As the organic inclusion compound for achieving the object of the present invention, β-cyclodexulin, and as the inorganic inclusion compound, there are aluminosilicates and the like. It becomes a clathrate as a clathrate compound in an intermediate state between the chemical means and the chemical means, and can maintain the aroma.

In the present invention, the abrasive grains, the filler, the compounding of the resin binder, etc., which are required for the performance of the resinoid rotary grindstone, are not particularly limited, and the manufacturing conditions thereof, that is, the firing conditions and the like are limited. not. Therefore, it is possible to carry out the above-mentioned grindstone as a wax-treated grindstone or as a grindstone mixed with low hardness inorganic particles independently or simultaneously with the present invention. For example, if a clathrate is blended in the waxy treatment liquid used for the waxy treatment described above, or a porous mineral or a fossil mineral is used as the low hardness abrasive,
For example, the inclusion perfume is retained by adsorption or the like. For example, natural porous minerals such as magnesium silicate (sepiolite), alkali salt of aluminosilicate (zeolite), aluminosilicate (activated clay), montmorillonite of clay mineral, and hydrohalloysite, and fossil minerals are solvent-bonded with organic matter. To hold the inclusion perfume inside the layer lattice. Further, the inclusion perfume can be retained in the hollow such as artificial inorganic hollow fine particles such as shirasu balloon, and can be used together with the low hardness abrasive grains and the filler, or in place of them. If these are subjected to a drying treatment in advance, the ability to retain the fragrance can be enhanced.

The target fragrance for the inclusion fragrance used in the present invention is not particularly limited, but since it is heated to about 180 ° C. in the production of resinoid grindstone, the fragrance preferably has a boiling point higher than that. Therefore, the following fragrances can be exemplified.

The fragrance is not limited to the above synthetic fragrance,
Natural fragrances can be used as long as they can withstand the high temperature during press molding.

<Function> The clathrate-containing grindstone of the present invention can be carried out simultaneously with the conventional processing means for enhancing cutting efficiency or preventing grinding burn, and if grinding or cutting work is carried out using this, As the whetstone wears, fragrance is released to the workplace,
The effect of making the working environment comfortable is obtained.

 The present invention will be described in detail below with reference to examples.

<Examples 1 to 3> 100 parts of white alundum WA # 46 as abrasive grains, 25 parts of calcite # 36, 16 parts of creorite as a filler, and 23 parts of phenol resin binder as a resin binder were generally used for resinoid grindstones. In accordance with the conventional blending method, the inclusion flavoring agent master resin pellets containing β-cyclodextrin inclusion compound containing 20% by weight of each of the above-mentioned flavoring agents of rose, chocolate, and bouquet are powdered and powdered.
Each of the compounded raw materials obtained as a result was heat-molded at 180 ° C. according to a conventional method to obtain a resinoid cutting grindstone.

A cutting test was performed on the obtained three types of resinoid cutting wheels and, as a comparative example, a fragrance-free wheel. For the cutting test, 16 mmφ rebar was used as the work material, and this was cut by an automatic cutting machine to monitor the scent before and after cutting. Table 1 shows the results.

As is clear from Table 1, the resinoid grindstones obtained by mixing and holding the clathrate in the grindstone raw material according to the present invention and then heat-molding all have cutting ability of 12 to 10 per sheet.
19 times, 10 to 12 seconds per time, no effect of perfume addition was observed, and an effect of exerting an aroma was obtained by use.

<Examples 4 to 6> The abrasive grains, the filler, and the phenol resin binder of the above examples were kneaded as raw material for the resinoid grindstone, and similarly heat-molded to obtain a resinoid cutting grindstone. On the other hand, cetyl alcohol 60 for waxy treatment of resinoid grindstone
%, Stearyl alcohol 40% to the waxy treatment liquid, rose, chocolate, bouquet each of the above-mentioned flavors 20
Inclusion perfume master resin pellets (β-cyclodextrin inclusion compound) containing 5% by weight of powder was added to the mixture in an amount of 5% by weight, and the mixture was kneaded again. The untreated resinoid cutting grindstone obtained in step 1 was dipped and impregnated with wax.

A cutting test was conducted in the same manner as in Example 1 on the three types of resinoid cutting wheels obtained and, as a comparative example, a perfume-free waxy wheel. Table 2 shows the results of the sensory test of the fragrance emitted by cutting.

As in this example, even when the resinoid grindstone after molding is subjected to the wax treatment and the addition of the inclusion perfume in the post-processing, the aroma is generated along with the cutting, which is effective.

<Examples 7 to 9> Next, examples of using an aromatic clathrate compound by an inorganic substance as an inclusion flavoring agent will be introduced.

The fragrance used here is citronellol, which is used as an inorganic substance in sepiolite, zeolite, activated clay and 10: 9.
The inclusion compound of 0 was used. 5 parts of this clathrate was added to the raw material of the grindstone having the same composition as in Example 1 to obtain a resinoid cutting grindstone according to a conventional method. These three types of resinoid cutting wheels were subjected to a cutting test in the same manner as in the above examples, and a sensory test was conducted to obtain the results shown in Table 3.

As is clear from Table 3, addition of the inclusion compound of the fragrance is effective as an embodiment of the present invention, and as a result, the cutting ability of the grindstone is not decreased.

<Effects of the Invention> The resinoid rotation grindstone containing clathrates according to the present invention ensures long-term durability of the fragrance, and by using the fragrance, it emits an aroma, and the burnt odor of the phenolic resin tends to accompany the working environment, Eliminate unpleasant odors such as metallic and oily odors to create a comfortable working environment. In addition, in the course of product distribution, the effect of increasing the product value by releasing the aroma from the grindstone product was obtained.
