The smell is causing the problem, causing significant discomfort to call consumers. To solve this problem, a bar made an attempt to introduce various deodorant or antimicrobial functional components in superabsorbent resin composition before.

However, in the conventional attempt to introduce these various deodorant / antibacterial functional ingredient, and not a deodorant / antibacterial properties of the water absorbent resin as filled curves. Sufficient, and lowering the stability of the water-absorbent resin causes the degradation of the fundamental absorption performance or , there was a disadvantage such as that such a functional component itself is too high in relation expensive price of the water absorbent resin composition is too high.

Accordingly, high indicates a better anti-bacterial and deodorant properties, without sacrificing the basic absorption performance of the water absorbent resin, has been to develop a water absorbent resin composition it is continuously request and having a good economical efficiency.

In a more specific embodiment, the particulate antimicrobial agent to may have a structure of formula (2), the particulate antimicrobial agent containing as a main component of these formula (2) trade name: "" 81 08 greater than 6 is commercially available as ":

[Formula 2]

As the particulate antimicrobial agent is used to obtain these commercial products, or U.S. Patent No. 6,572,926, 1 - No. 6,146,688, No. 7,851,653 may be used to direct synthesis in the known methods) or (No. 7858141 or the like.

The particulate antimicrobial agent is used in addition to the particulate water absorbent resin logo 2019/103316 1 »(1 ^ 1 {2018/012433

May be, This allows one embodiment and has a water-absorbent resin composition can exhibit more excellent deodorant / antibacterial properties.

The particulate antimicrobial agents is the high water-absorbent resin particles with respect to 100 parts by weight, can be included in an amount of 0.2 to 5 parts by weight, or 0.5 to 4 parts by weight. This allows, and while still further improve the antimicrobial / deodorizing properties of the water absorbent resin composition, such or that by the component decreases the stability of the water-absorbent resin particles it can be minimized such that the absorption properties deteriorated.

On the other hand, one embodiment the resin composition can further include an additional antimicrobial / In order to accomplish the deodorant properties, £ 1 肝 show or a chelating agent and / or containing the alkali metal salt of an organic acid, and silicate-based salt mixture.

Of these, the chelating agent contains a chelating agent, for example, to one of ordinary skill in the art is well known, sodium salt (EDTA-2Na), or may use an amine acid compound, a particular sodium pyoyi

In addition, ethylenediamine teteurayi, sets acid, cyclohexane nucleic tetraacetic acid, diethylenetriamine pentaacetic acid, ethylene glycol bis (aminoethyl ether) -代刀'- tree acetic acid,]本(2-hydroxyethyl) -ethylene diamine -民'- that tree acid and triethylenetetramine hex selected from the group consisting of ethyl acetate, the amine compound, or may use various chelating agents as a matter of course.

These chelating agents may be present in the above high water-absorbent resin particles to cause the particulate antimicrobial agent, or an organic acid, and silicate-based salt mixture with synergistic effect, as a result, one embodiment and the water absorbent resin composition enhanced deodorant / antibacterial

2019/103316 1»（：1^1{2018/012433

It can be to indicate the characteristic.

The chelating agent and the water-absorbent resin particles for 100 parts by weight, may be included in the range of 0.1 to 3 parts by weight, or from 0.5 to 2 weight parts of the content. This allows, and while still further improve the antimicrobial / deodorizing properties of the water absorbent resin composition, or that by such a component is reduced stability of the water-absorbent resin particles can be minimized such that the absorption properties deteriorated.

On the other hand, one embodiment superabsorbent resin composition also may be further comprising an organic acid and a silicate-based salt mixture. These organic acids and can be present in the silicate salt, too high water-absorbent resin particles.

The silicate salt may be in a salt form, the cation of the silicate anion is an ionic bond and the alkali or alkaline earth metal, can be present in a particle state. The silicate salt particles is 150 / more than 600 L 11 can contain the particles having a particle size less than from about 80 to about 98% by weight, or from about 90 to about 99% by weight, or from about 92 to about 99.3% by weight.
