Description

  The present invention relates to a sodium dichloroisocyanurate-containing tablet, and in particular, adjusts the time until the end of foaming of a tablet that decomposes, disperses (dissolves) in water and exhibits sterilization, washing, deodorization and the like over a long period of time. It relates to a tablet containing sodium dichloroisocyanurate that can be controlled.

  Conventionally, tablets containing sodium dichloroisocyanurate have been widely used as bath water purifiers and pipe cleaning agents that reduce the turbidity and off-flavor of bath water used by recooking bath water bathed by the whole family the next day (for example, And Patent Documents 1 and 2).

By the way, these bath water purifiers and pipe cleaners end foaming (disintegration) in a short time in water, so that the components in the tablet are released over a long period of time, and the effect is maintained for a long time. There was a problem that could not.

  In view of the problems of the conventional sodium dichloroisocyanurate-containing tablets, the present invention is able to adjust and manage the time from when a tablet is put into water until foaming is completed over a long time. An object is to provide a sodium acid-containing tablet.

  In order to achieve the above object, the sodium dichloroisocyanurate-containing tablet of the present invention is characterized in that an organic acid, carbonate, bicarbonate and polyacrylic acid are blended with sodium dichloroisocyanurate.

  In this case, 1 to 6 parts by weight of polyacrylic acid can be blended with 35 parts by weight of sodium dichloroisocyanurate.

  According to the sodium dichloroisocyanurate-containing tablet of the present invention, by blending organic acid, carbonate, hydrogen carbonate and polyacrylic acid with sodium dichloroisocyanurate, in particular, polyisocyanate is a kind of superabsorbent polymer. By blending acrylic acid, it is possible to adjust and manage the time from foaming to the end of foaming for a long time, and release the tablet components for a long time if necessary. It is possible to provide a tablet containing sodium dichloroisocyanurate that can be made to do so.

  In addition, by blending 1 to 6 parts by weight of polyacrylic acid with respect to 35 parts by weight of sodium dichloroisocyanurate, it is possible to easily adjust and manage the foaming end time of the tablet by changing the blended amount of polyacrylic acid. it can

  Hereinafter, embodiments of the sodium dichloroisocyanurate-containing tablet of the present invention will be described with specific examples.

  The sodium dichloroisocyanurate-containing tablet of the present invention is one in which an organic acid, carbonate, bicarbonate and polyacrylic acid are blended with sodium dichloroisocyanurate.

Here, as the organic acid, one kind of organic acid such as succinic acid, glutaric acid, adipic acid or citric acid can be used alone, or a plurality of kinds can be used in combination.
Moreover, carbonates, such as sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, etc. can be used independently, or multiple types can be used together.
Moreover, hydrogencarbonate, such as sodium hydrogencarbonate and potassium hydrogencarbonate, can be used alone, or a plurality of types can be used in combination.

And 1-6 weight part of polyacrylic acid can be mix | blended with respect to 35 weight part of sodium dichloroisocyanurate.
In this case, it is preferable to change the blending amount of carbonate or bicarbonate with respect to the increase or decrease of the blending amount of polyacrylic acid.

  In Table 1, the ratio of the compounding quantity of each component of the more specific Example of the sodium dichloroisocyanurate containing tablet of this invention is shown.

  In the table, A is sodium dichloroisocyanurate, B is succinic acid, C is sodium carbonate, D is sodium hydrogen carbonate, and E is polyacrylic acid.

In Table 2, the measurement result of the foaming end time of the sodium dichloroisocyanurate-containing tablet of the present invention is shown.
In the test method, 1 liter of water was put into a 2 liter beaker, and the time until the end of foaming of 3 g of a tablet (solid foaming agent) obtained by tableting the powder having the component ratio shown in Table 1 was measured.

  As shown in Table 2, the sodium dichloroisocyanurate-containing tablet of Example 1 containing 4% of polyacrylic acid in the total blending component had a foaming end time of 55 minutes, and polyacrylic acid was 1% of the total blending component. Compared to the sodium dichloroisocyanurate-containing tablet of Example 3 and the commercially available product (Comparative Example), it was confirmed that the tablet components could be released over a long period of time.

In addition, the sodium dichloroisocyanurate-containing tablet of Example 3 containing 1% of the total blending component of polyacrylic acid had an end-of-foaming time of 3 minutes and 30 seconds, which was approximately the same as that of a commercially available product (Comparative Example). 1.35 times.
As described above, the foaming end time changes in proportion to the amount of the polyacrylic acid compounding component, and the foaming end time of the sodium dichloroisocyanurate-containing tablet can be easily adjusted by changing the amount of the polyacrylic acid compounding component. , Confirmed that can be managed.

  As described above, the sodium dichloroisocyanurate-containing tablet of the present invention has been described based on the examples thereof, but the present invention is not limited to the configurations described in the above examples, and may be appropriately selected within the scope of the invention. The configuration can be changed.

  The sodium dichloroisocyanurate-containing tablet of the present invention has a characteristic that the time from when the tablet is put into water to when foaming is completed can be adjusted and managed over a long period of time. It can be suitably used for water purification agents and pipe cleaning agents.
