吸着するための脱臭剤に関する。TECHNICAL FIELD The present invention relates to a deodorant, and more specifically, to an acidic gas component represented by aldehydes,
The present invention relates to a deodorant for simultaneously adsorbing a basic gas component represented by amines well.

Description of the Related Art In the interior of a house or the interior of an automobile, volatile substances such as acetaldehyde and other aldehydes, acidic gas components such as trimethylamine and amines or basic gas components such as ammonia can be used. It contains a lot of odorous components, and its removal is desired.

が黒色であるため用途が限定される点等の問題もある。Conventionally, generally, odorous components are absorbed and
Activated carbon is widely used as a deodorant for removal, but activated carbon has selectivity for the type of odorous component to be adsorbed, and for example, it does not necessarily have good adsorption capacity for nitrogen-containing compounds such as acetaldehyde and amines. Does not exert.
Further, there are problems such that the adsorbed malodorous component is easily desorbed again, and the use is limited because the activated carbon is black.

る。Further, since the deodorant disclosed in Japanese Patent Laid-Open No. 7-313872 has a double salt of phosphoric acid and hydrazine supported on a porous mineral whose surface is composed of silica, acetaldehyde and the like can be eliminated. It is considered that aldehydes and nitrogenous odorous components such as amines and ammonia can be adsorbed together, but there is a problem in using hydrazine which is a carcinogen, and it is a component for adsorption. However, there is a problem that these components are easily dropped off during use because of being physically attached to the carrier, and for this reason the adsorption capacity is likely to decrease.

ら脱落し難いと言う利点がある。On the other hand, the adsorbent for acidic gas disclosed in Japanese Unexamined Patent Publication No. 8-257346 has a method in which a carrier made of a porous metal oxide such as silica, alumina, titania, zirconia having a large number of hydroxyl groups on its surface is used as an amino acid. An organic silicon compound containing a group is supported. This acid gas adsorbent is considered to exhibit good adsorption performance for at least acidic odor components such as acetaldehyde and hydrogen sulfide,
Further, since the organosilicon compound is chemically bonded to the porous metal oxide (condensation of the hydroxyl group of the porous metal oxide with the hydroxyl group or alkoxy group of the organosilicon compound), it is said that the organosilicon compound does not easily fall off from the carrier. There are advantages.

に吸着する脱臭剤を構成できる可能性がある。By the way, the hydroxyl groups in the carrier such as a porous metal oxide having a large number of hydroxyl groups on the surface (outer surface and inner surface of pores) are bound by the amino group-containing component as described above. It can be used as a carrier,
As such, it can function as a trapping means for the basic gas component. Therefore, it is possible to construct a deodorizing agent that simultaneously and satisfactorily adsorbs an acidic gas component and a basic gas component, by properly using these large numbers of hydroxyl groups as the above means and by using them in a well-balanced manner.

In the acid gas adsorbent according to No. 6, since only the use of hydroxyl groups as the above means is considered, an excess amount of the organosilicon compound relative to the total amount of hydroxyl groups on the surface of the porous metal oxide is considered. As a result, good adsorption performance for basic gas components cannot be expected.

アミノ基含有化合物として最適であるとは言えない。Further, the prior art disclosed in Japanese Patent Application Laid-Open No. 8-257346 discloses only an organosilicon compound in which one aminoalkyl group and three hydroxyl groups or alkoxy groups are bonded to a silicon atom. However, when such an organosilicon compound is carried on the surface of the porous metal oxide 1 as shown in FIG. 1 (a), it may be bonded to a plurality of hydroxyl groups as shown in FIG. 1 (b). At one point, as shown in FIG. 1 (c), there is a strong tendency to form a polymer that polycondenses with each other to block the pores of the porous metal oxide,
It cannot be said that it is the most suitable as an amino group-containing compound.

It is a problem to be solved to provide a deodorant that is not afraid and can simultaneously adsorb an acidic gas component and a basic gas component in good balance.

Therefore, for example, when the deodorant is mixed with a binder such as an acrylic resin emulsion, the amino group-containing silicon compound does not fall off from the carrier (porous substance).

ス成分を吸着する。The amino group contained in the amino group-containing silicon compound adsorbs an acidic gas component typified by aldehydes such as acetaldehyde, and the hydroxyl group not involved in supporting the amino group-containing silicon compound is trimethylamine or the like. Adsorbs basic gas components represented by amines or ammonia.

は単なる化学量論的計算によっては決定できない。From this point of view, the relative amount between the amount of the amino group-containing silicon compound supported and the amount of the hydroxyl group not involved in the support of the amino group-containing silicon compound is stoichiometrically calculated and adjusted, It should be possible to make the adsorption performance of the acidic gas component and the adsorption performance of the basic gas component both good, but in reality, the adsorption ability of the amino group for the acidic gas component and the adsorption ability of the hydroxyl group for the basic gas component, And the steric hindrance of the bulky amino group-containing silicon compound with respect to the adsorption of the basic gas component by the hydroxyl group, and the like, the above-mentioned appropriate relative amount cannot be determined by simple stoichiometric calculation.
【００１７】そして本願発明者は、上記の水酸基結合率
が０．１〜１０％を占めるとき、酸性ガス成分の吸着性
能と塩基性ガス成分の吸着性能とが良好に両立すること
を、実験的に究明した。The inventor of the present application has experimentally determined that when the above hydroxyl group bonding rate is 0.1 to 10%, the adsorption performance of the acidic gas component and the adsorption performance of the basic gas component are well compatible with each other. Investigated.

能な吸着性能とを同時に得ることができる。That is, when the hydroxyl bond rate is less than 0.1%, the basic gas component adsorption capacity is sufficient, but the acidic gas component adsorption capacity is insufficient. However, as long as the hydroxyl bond rate is within the range of 0.1 to 10%, it is always the minimum satisfactory adsorption performance for acidic gas components and the minimum satisfaction for basic gas components that is higher than that of activated carbon, which is a general-purpose adsorbent. It is possible to obtain the possible adsorption performance at the same time.

性ガス成分の吸着能力も飽和する傾向が見られる。On the other hand, a hydroxyl group bonding rate of about 10% is one kind of critical point. When the hydroxyl group bonding rate exceeds this critical point, steric hindrance of the bulky amino group-containing silicon compound molecule becomes remarkable. In addition, the adsorption of basic gas components by hydroxyl groups is significantly impaired, the adsorption ability is lower than that of activated carbon, and the adsorption ability of acidic gas components tends to be saturated.

に近い側に水酸基結合率をシフトさせれば良い。Therefore, depending on the purpose of use and environment of use of the deodorant, when it is desired to relatively enhance the adsorption ability of the basic gas component, the side closer to the lower limit of the range of 0.1 to 10% of the hydroxyl group bonding rate. When it is desired to shift the hydroxyl group binding rate to (1) to relatively enhance the acid gas component adsorption capacity, the hydroxyl group binding rate may be shifted to the side closer to the upper limit of the above range.

ることは言うまでもない。The above-mentioned actions and effects of the first invention relate to the realization of a good balance between the adsorption ability of the acidic gas component and the adsorption ability of the basic gas component by appropriately adjusting the hydroxyl group binding rate. Apart from this, if the absolute value of the total number of hydroxyl groups on the surface of the porous substance (and thus the absolute value of the amount of the silicon compound containing amino groups supported) becomes large, the absolute adsorption capacity of both gas components will be correspondingly increased. It goes without saying that the value will increase.

きる。(Operation and effect of the second invention) In the second invention, since the amino group-containing silicon compound bonded to and supported by the porous substance has one or more amino groups, the number of amino groups is 1 depending on the number of the amino groups. The ability to adsorb acidic gas components per amino group-containing silicon compound of the molecule can be relatively increased.

る恐れが少ない。Further, since the amino group-containing silicon compound has only one bonding functional group used for bonding with the hydroxyl group on the surface of the porous material, it is possible to surely achieve the binding and supporting of the porous material. As in the prior art, excess hydroxyl groups on the surface of the porous material are consumed more than necessary due to excess binding functional groups, or excess binding functional groups are polycondensed with each other to block the pores of the porous material. Less likely to form polymers.

As a result, the balance between the amino group-containing silicon compound and the hydroxyl group becomes particularly good, and the activities of both are further improved. Therefore, the ability to adsorb basic odor components such as amines and ammonia and the ability to adsorb acidic odor components such as aldehydes are remarkably increased, and both odor components can be adsorbed and removed at a high level at the same time.

m 2 / g or more and the number of hydroxyl groups on the surface is 2 / nm 2
The above is silica gel. Such porous metal oxide,
The pore structure is good, and the absolute value of the total number of hydroxyl groups on the surface (and thus the absolute value of the amount of the amino group-containing silicon compound supported) is large. Therefore, the adsorption capacity of the acidic gas component and the basic gas component are large. The absolute value of the adsorption capacity of is also large. When the specific surface area is less than 500 m 2 / g or the number of hydroxyl groups on the surface is less than 2 / nm 2 , the number of all hydroxyl groups per unit amount of the deodorant is not sufficient. Dissatisfaction remains.
