This Si—H group-reactive compound is for adding to the unreacted Si—H portion of the silicone compound to introduce a desired pendant group into the silicone compound. Therefore, various functions can be imparted to the powder by appropriately selecting the Si—H reactive compound and introducing a desired pendant group. Here, the “pendant group” is a residue of a compound capable of reacting with a Si—H group portion, and means a group introduced into a silicone compound by an addition reaction of the compound.
The pendant groups impart various properties and functions to the powder. The hydrophobicity can be further enhanced by adjusting the type or length of the hydrocarbon group of the unsaturated compound to be added.

The pendant group can be arbitrarily selected. For example, an alkyl group has a high water repellency and is well dispersed in fats and oils, and the addition of an ultraviolet absorber makes it possible to obtain an ultraviolet absorbing powder without percutaneous absorption. If a group having an antibacterial action is added, an antibacterial powder without percutaneous absorption can be obtained. Those having an epoxy group added thereto can react with the resin, form a strong resin-powder composite, and become a hard composite that does not expand due to heat.

As the Si—H group reactive compound,
For example, a compound having an OH group or SH group, for example, an amino acid (such as cysteine) can be used. Further, an unsaturated compound (vinyl compound) having at least one carbon-carbon double bond or triple bond and capable of reacting with the Si-H group portion can be used.

It is characterized in that it is added at a high density of at least μmol / g.
By introducing a functional group into the powder at such a high density, not only the functionality can be sufficiently exhibited, but also the performance different from the conventional one can be exhibited. Such a functional powder can be applied to various fields such as cosmetics, paints, and composite materials.

The method of coating the silicone compound having a Si—H group with a powder and the method of adding a functional group can be performed by conventional means.

With respect to the method of coating a silicone compound having a Si—H group with a powder, for example, the above silicone compound is dissolved in an organic solvent (chloroform, hexane, benzene, toluene, acetone, etc.), and the powder is added thereto. The powder can be coated with the silicone compound film by dispersing to prepare a dispersion, heating the dispersion to evaporate the solvent, and forming a film on the powder surface. Alternatively, the powder is poured by pouring the dispersion into the poor solvent of the silicone compound, or by pouring the poor solvent into the dispersion and adhering the insolubilized silicone compound onto the powder surface to form a film thereof. The body may be covered.
Further, as in the in-situ polymerization method, the powder may be encapsulated with a coating of the silicone compound by subjecting the silicone compound to monomer polymerization in the presence of a catalyst on the surface of the powder. Alternatively, coating can be carried out by utilizing active sites widely distributed on substantially the entire surface of the powder.

The silicone compound may be sprayed on the powder as it is, or the silicone compound may be sprayed after the powder is dissolved in a solvent.

Alternatively, the powder is preferably coated with the silicone compound in water or an aqueous solvent. The aqueous solvent means a solution containing water as a main component and containing about 80% by weight or more of water. Other components other than water include alcohols such as ethanol, methanol, and isopropanol, sodium hydroxide, potassium hydroxide, calcium hydroxide, hydrochloric acid, sulfuric acid, and mixtures thereof. In addition, examples of water contained in the aqueous solution include ion-exchanged water and distilled water, and inorganic water may be present in the water. As inorganic ions, L

_{^{SO4 -, SO 4 2-, PO}} 4 3-, Cl - , and the like. By changing the content of these ions, the pH of the aqueous system can be controlled, and as a result, the addition reaction of the pendant group in the aqueous system can be controlled. That is, if the pH value is increased by increasing the amount of inorganic ions, Si—H
The crosslinking of the groups can be promoted, while the degree of crosslinking can be suppressed by reducing the amount of inorganic ions and decreasing the pH value. Therefore, by reducing the pH value,
By increasing the number of remaining Si-H groups by making it difficult for i-H groups to crosslink, the additional density of pendant groups by the hydrosilylation reaction described later can be increased. In the present invention, a compound having a pendant group is added in an amount of 100 μmol per powder.
It is preferable to control the pH to about 5 to 8 in order to add at a high density of / g or more.

The ratio between the silicone compound and the aqueous solution varies depending on the method of mixing the powder, but it is preferable to carry out the reaction in the range of 0.1 to 100 (weight ratio) of water to 1 silicone.
More preferably, it is 5 to 50. The mixing method can be performed by a conventional method using a commonly used mixer. In the case of wet mixing, the amount of water used is slightly larger,
In the case of dry mixing, the amount of water is slightly smaller.

The amount of the silicone compound with respect to the powder is 2-2.
It is preferably 0% by weight, more preferably 3 to 10% by weight. When the amount of the silicone is less than 2% by weight, a pendant group cannot be introduced to the extent that the effects of the present invention can be obtained. Further, the Si—H group-reactive compound is used in the range of 0.5 to 3 of the Si—H group of the silicone compound of the entire system.
Equivalents are preferred, more preferably 1-2 equivalents. Water is mixed with the above amount of silicone compound at the above-mentioned ratio and used as a reaction liquid.

The thus-obtained silicone-coated powder has an unreacted Si-H group, and becomes slightly unstable under severe conditions such as alkali and acid.

Next, a compound capable of reacting with the Si—H group is added to the unreacted Si—H group of the silicone compound coated with the powder. Thereby, the Si—H reactive compound is added to the unreacted Si—H portion of the silicone compound, and a pendant group derived from the Si—H reactive compound is introduced into the silicone compound. By appropriately selecting the Si—H reactive compound and introducing a desired pendant group, various functions can be imparted to the powder.

This will be further described below.
In the step of the coating process, cross-linking between Si-H groups occurs on the powder surface to form a network structure, and the powder surface is coated with a coating of a silicone compound. Not done. For this reason, residual Si-H groups are present and tend to be slightly unstable under severe conditions such as alkalis and acids. This remaining Si-H group is replaced with Si-H
By adding a reactive compound (for example, an unsaturated compound such as an alkene or an alkylene, etc.) by a hydrosilylation reaction to generate a Si—C bond, a powder more stable to an alkali or an acid can be obtained. it can.

Therefore, various functions can be imparted to the powder by appropriately selecting a Si—H reactive compound (unsaturated compound, etc.) and introducing a desired pendant group. Here, the “pendant group” refers to Si—H
A residue of a compound capable of reacting with a base moiety,
It means a group introduced into the silicone compound by the addition reaction of the compound. The pendant groups impart various properties and functions to the powder. The hydrophobicity can be further enhanced by adjusting the type or length of the hydrocarbon group of the unsaturated compound to be added.

In the present invention, the pendant S
i-H reactive compound was added to 100 g
1 / g or more, preferably 150 μmol / g or more, more preferably 200 μmol / g or more.

Incidentally, both the coating of the silicone compound and the addition reaction of the pendant group may be carried out in an aqueous solution.
For example, a predetermined amount of a silicone compound having a Si-H group, a compound capable of reacting with the Si-H group, and water are charged into a mixer, and after mixing, the mixed solution is sprayed on powder as a mist, A method in which the mixture is heated and mixed, and a catalyst is further added thereto. Further, an aqueous solvent is put into a kneader containing powder, and after stirring and mixing well, a silicone compound having a Si-H group and a compound capable of reacting with the Si-H group are added, and the mixture is heated and mixed to form a catalyst. Addition allows simultaneous coating and addition. The reaction by this contact is preferably carried out while heating, since this shortens the reaction time.

Further, it may be supplied in the form of a gas, or may be stirred and mixed together with the powder by a ball mill or the like. When supplied in gaseous form, those having a low boiling point are desirable.

The heating temperature can be in the range of 50 to 120 ° C., but the higher the temperature, the higher the reaction rate and the shorter the reaction time.

Next, a catalyst is added to promote a hydrosilylation reaction between the Si—H group and the pendant group of the silicone compound.
