The present invention relates to organopolysiloxane compositions that provide products suitable for tooth cleaning. Silicone rubber products, which are highly effective for cleaning teeth, are used by pressing and rubbing them against the teeth and gums to remove deposits, so they must have an appropriate hardness and brittleness. It is extremely important to have flexibility, flexibility, etc. This is because if the cured rubber product is too hard, the filler contained in the product will fall off during cleaning, while if it is too soft, it will become weak and cannot withstand use. Furthermore, the fragility is due to the fact that appropriate fragility is required to prevent teeth or gums from being damaged by the wear of the rubber product itself during use. Usually, various fillers are added to synthetic rubber such as butadiene-styrene rubber, neoprene rubber, butadiene-acrylonitrile rubber, silicone rubber, etc., but synthetic rubbers other than silicone rubber are hardened, increased in weight, or processed. In silicone rubber, it is used to improve mechanical strength (reinforcing effect). However, in silicone rubber products for tooth cleaning, it is important for the filler to provide the above-mentioned physical properties rather than the conventional reinforcing effect, and for this purpose, particle size, particle shape, particle size distribution, etc. It is necessary to choose. The present inventors have conducted extensive research on organopolysiloxane compositions that are suitable for cleaning teeth. The present invention was completed based on the discovery that the combined use of soil is extremely effective. That is, the present invention has the following features: (a) Average composition formula RaSiO is a methyl group.a
is a number from 1.85 to 2.10) 100 parts by weight of an organopolysiloxane, (b) an inorganic filler with an average particle size of 10 to 100 μm
50 to 300 parts by weight, (c) diatomaceous earth with an average particle size of 1 to 10 μm
30 to 100 parts by weight, (d) Diatomaceous earth with an average particle size of 50 to 100 μm
It consists of 5 to 50 parts by weight and (e) a curing agent. Next, to explain the composition of the present invention in more detail, first, the organopolysiloxane represented by the above average composition formula as the component (a) used in the present invention is one that is conventionally known as the main raw material of silicone rubber. It is a diorganopolysiloxane with a substantially linear structure. However, a in the formula
A trifunctional siloxane unit may be introduced as long as it is within the range of 1.85 to 2.10, and the end of the molecular chain may have any structure such as a vinyldiorganosilyl group, triorganosilyl group, or hydroxydiorganosilyl group. In order to make a good rubber elastic body, it must be 1000 centistokes or more at 25℃, especially
It is desirable that the polymerization degree is such that it exhibits a viscosity of 5000 centistokes or more. R in the formula includes alkyl groups such as methyl group, ethyl group, isopropyl group, butyl group, 2-ethylbutyl group, and octyl group, alkenyl groups such as vinyl group, allyl group, and hexenyl group, cyclohexyl group, cyclopentyl group, etc. cycloalkyl groups, aryl groups such as phenyl groups, tolyl groups, and xylyl groups, aralkyl groups such as benzyl groups and phenylethyl groups, or hydrogen atoms of these hydrocarbon groups are partially substituted with halogen atoms, cyano groups, etc. Examples include groups. In the present invention, component (a) requires that at least 50 mol% of all the monovalent hydrocarbon groups represented by R in the formula be methyl groups. The inorganic filler as the component (B) imparts an abrasive action to the product obtained from the composition of the present invention, and the inorganic filler as the component (B) has an average particle diameter of 10 to 10.
It is essential that the average particle size be within the range of 100μm, but this is because if the average particle size is less than the above range, a sufficient tooth cleaning effect will not be obtained, whereas if it is above the above range, it may actually cause damage to the teeth. This is because it can have negative effects such as causing damage. Such components (b) include crystalline silica, fused silica, calcium carbonate, aluminum oxide,
Examples include magnesium carbonate. The amount of component (b) used is in the range of 50 to 300 parts by weight per 100 parts by weight of component (a) above, but if it is less than the above range, sufficient abrasive action cannot be imparted. On the other hand, if it exceeds the above range, it is not only economically disadvantageous, but also the final product becomes too brittle. Next, diatomaceous earth as components (c) and (d) used in the present invention is blended for the purpose of imparting appropriate brittleness to the product obtained from the composition of the present invention. From the standpoint of achieving this, it is essential to use two types of diatomaceous earth with different average particle sizes. As mentioned above, diatomaceous earth as the component (c) is used to impart appropriate hardness and brittleness to the product obtained from the composition of the present invention, and
It is essential that this material has an average particle diameter in the range of 1 to 10 μm. An example of such diatomaceous earth is Celite Super Floss (trade name, manufactured by Johns Manville). The amount of this component (c) used is 30 to 100 parts by weight per 100 parts by weight of component (a) above.
This is because if the amount used is outside the above range, the object of the present invention as described above cannot be achieved. Diatomaceous earth as component (2) is used for the same purpose as component (c) above, and it is essential that this material has an average particle size in the range of 50 to 100 μm. Specifically, as such diatomaceous earth, Radiolite #900 (product name manufactured by Showa Kagaku Co., Ltd.) is used.
is exemplified. The usage amount of this (d) component is the amount of the above (b) component.
The amount is in the range of 5 to 50 parts by weight per 100 parts by weight. As the curing agent which is component (2), various conventionally known curing agents can be used depending on the mechanism of the crosslinking reaction. For example, when the crosslinking reaction is carried out between hydrocarbon groups, organic peroxides are used, including benzoyl peroxide, 2,4-dichlorobenzoyl peroxide, 2,4-dicumyl peroxide, 2,5 Examples include -dimethylbis(2.5-tert-butylperoxy)hexane, di-tert-butyl peroxide, and tert-butyl perbenzoate. In addition, when the component (a) has a hydroxyl group at both ends of the molecular chain, curing can be carried out by dealcoholization reaction, decarboxylation reaction, deoxime reaction, etc. In this case, methyltriacetoxysilane ,
Methyltributanoxime silane, methyl (or vinyl, phenyl) trialkoxysilane,
Metal organic acid salts and organic amines are used along with crosslinking agents such as ethyl (or propyl) orthosilicate; these include dibutyltin dilaurate, tin dioctenate, iron stearate, lead octylate, dibutylamine, triethanolamine, etc. A curing accelerator may be used. Furthermore, when the organopolysiloxane as the component (a) described above has a vinyl group bonded to a silicon atom, a compound having a hydrogen atom directly bonded to a silicon atom, that is, an organohydrodiene polysiloxane, is used as a crosslinking agent to form platinum. When used with system catalysts, crosslinking can be effected by addition reactions and thereby curing can be achieved. The organohydrodiene polysiloxane used here may be linear, branched or cyclic. As the platinum-based catalyst, it is preferable to use chloroplatinic acid, an alcohol compound of chloroplatinic acid, a complex of chloroplatinic acid and olefins, or the like. The composition of the present invention can be produced by uniformly mixing prescribed amounts of the above-mentioned components (a) to (d) using a kneader such as a roll, kneader, or Banbury mixer (internal mixer) that is commonly used for kneading silicone rubber. It is obtained by kneading. In addition, when obtaining a molded article using the composition of the present invention prepared as described above, the composition may be processed by a pressure molding method, an extrusion molding method, a calendar molding method, or a casting molding method. The material may be molded into a desired shape using the following molding method, and then cured. Examples of the curing method include heating or irradiation with ionizing radiation. The composition of the present invention may contain fungicides such as potassium sorbate and butyl benzoate, pigments, fragrances, antioxidants, additives thereof, etc., as necessary, within the range that does not impair the purpose of the present invention. There is no problem in mixing them. The composition of the present invention can be formed into, for example, a round bar shape and lightly rubbed against the teeth and gums.
It is possible to reliably remove rotten matter adhering to them, and there is no risk of damaging teeth or gums during this process.Also, since this is a solid substance, it is not necessary to use water or other liquids when using it. It has practical effects of being convenient to carry and easy to use at any time. Next, examples of the present invention will be given, in which parts are by weight. Example The relative viscosity of a 1% toluene solution at 20°C is
2.2, the organic groups bonded to the silicon atom are methyl groups and vinyl groups, and the amount of vinyl groups in all these organic groups is 0.2 mole.Both ends of the molecular chain are blocked with dimethylvinylsilyl groups. Polysiloxane raw rubber 100 parts, formula
