Description

  The present invention relates to a deodorizing paper and a method for producing the same. More specifically, the present invention relates to a deodorizing paper for deodorizing manure odor generated from a toilet or the like and a method for producing the same.

The fecal odor generated from defecation, toilets after urination and portable toilets is unpleasant, and there is a need for a method for efficiently deodorizing. For example, when the number of times of cleaning is small for the use frequency in a public toilet or the like, the whole facility smells of manure. Further, when a portable toilet is used in a living room or a sick room, an odor of manure is smelled in the whole room, and therefore an effective deodorizing method is required.
As a deodorizing method for the toilet or portable toilet, a method of adding a deodorizing agent after defecation is mainly used.
As a form of the medicine to be used, liquids, tablets and sprays are commercially available. Many liquids use surfactants and chlorine compounds, and their deodorizing performance is insufficient. Further, since the deodorant liquid itself has a peculiar odor, there is a problem that the component of the deodorant liquid smells after use.

Furthermore, the tablet contains a foaming agent and is crushed when put into a toilet or portable toilet. However, since the tablet first sinks to the bottom when it is put in and starts crushing at the bottom, the tablet does not spread so much in the excretion container or excretion tank, and the effect is not sufficient.
In addition, spray type deodorants are sprayed toward feces and urine after defecation, so they are effective immediately, but soon evaporate and have no sustainability. Therefore, the effect is small when it cannot be processed immediately after defecation in a portable toilet. Moreover, since the can of a container will generate | occur | produce as a waste if it is a spray, it is not a preferable product form from an environmental and recycling viewpoint.

  On the other hand, organic deodorizers such as fragrance-based ones using plant extract oil and ones using organic acids are known as deodorants aimed at removing feces and urine odors. For example, Patent Document 1 discloses a deodorant containing an extract from mushrooms as an active ingredient, and Patent Document 2 discloses a deodorant containing a hydrophilic solvent extract of walnuts as an active ingredient. ing. Patent Document 3 proposes a liquid deodorant containing a polyphenol component extracted from apple as an active ingredient. Patent Document 4 discloses a toilet deodorant containing a polymer having a specific structure having a biguanidine group. Has been proposed.

Furthermore, a deodorant containing an inorganic compound as a main component and having the ability to deodorize bad odors generated from the living environment is also known. For example, Patent Document 5 discloses an erasing product that has a composition composed of a powder of a specific inorganic material A as a main component and a powder of a specific inorganic material B as a subcomponent, and is baked and solidified at a low temperature. An odorant is disclosed.
Patent Document 6 discloses a deodorant component comprising a zinc compound, a weak alkaline substance, and if necessary, an aliphatic polycarboxylic acid or a salt thereof.
Furthermore, Patent Document 7 discloses an antibacterial / deodorant composition comprising basic zinc carbonate and / or zinc oxide and oxycarboxylic acid, the molar ratio and pH of which are in a specific range.

  The organic or inorganic deodorant is used as it is or after being diluted with a solvent and then sprayed with a spray. Moreover, if it is a powder, it is used by the method of filling a bag or a container and leaving it in the vicinity of a bad odor generating source, or it is used by the method of kneading into various resin moldings or paints.

  Patent Document 8 discloses deodorant paper in which a specific inorganic deodorant composition is supported on water-soluble paper.

JP-A-2-277456 Japanese Patent Laid-Open No. 11-226099 JP 11-319051 A Japanese Patent Laid-Open No. 11-11040 JP 11-319048 A Japanese Patent Laid-Open No. 1-8971 JP-A-10-328280 JP 2003-49396 A

However, it cannot be said that the deodorizers described in Patent Documents 1 to 7 have a sufficient deodorizing effect on manure odor containing various odor components. Among spray-type deodorants that combine multiple deodorants, those that contain insoluble ingredients in water were partially dehydrated and inhomogeneous, making them unusable. . In the completely dissolved state, there is a problem that the deodorizing performance is lowered due to the interaction between the two, and none of the methods exhibits a sufficient deodorizing function.
Moreover, even the deodorizing paper described in Patent Document 8 has a problem that the deodorizing effect on manure odor is not sufficient or the solubility in water is poor.

In order to obtain excellent deodorizing performance against manure odor, the basic gas deodorant / sulfur-based gas deodorant is preferably in the range of 20/80 to 80/20 (mass ratio).

<Water-soluble binder>
The water-soluble binder used in the present invention is a water-soluble polymer for adhering an inorganic deodorant to water-soluble paper. Specific water-soluble binders include, for example, methyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl methyl cellulose, hydroxyl ethyl cellulose, hydroxypropyl cellulose, carboxyl methyl cellulose, carboxyl ethyl cellulose, polyvinyl pyrrolidone, polyvinyl alcohol, polymethyl acrylate, polyethyl acrylate, Examples thereof include polymethyl methacrylate, polyethyl methacrylate and derivatives thereof, and mixtures thereof. A preferred water-soluble binder is polyvinyl alcohol because it has a good balance between adhesion and water solubility.

  The mass ratio between the inorganic deodorant and the water-soluble binder is preferably 90/10 to 50/50, and more preferably 80/20 to 60/40. When the mass ratio is in the range of 90/10 to 50/50, the inorganic deodorant is sufficiently adhered to the water-soluble paper and the solubility in water is good.

<Moisture content>
The moisture content of the deodorant paper according to the present invention was manufactured by applying a deodorant dispersion containing an inorganic deodorant, a water-soluble binder, and water or a mixed solvent containing water, and then drying. This is a value calculated using the weight before and after drying for 2 hours at 105 ° C. using water-soluble paper. A detailed measurement method will be described later.
The moisture content of the deodorant paper according to the present invention is 5 to 15% by mass, preferably 5.5 to 14% by mass, and more preferably 6 to 13% by mass. When the moisture content of the deodorant paper is less than 5% by mass, the dissolution rate in water is reduced, and the deodorization performance is also reduced by causing undissolved residue. On the other hand, when the content exceeds 15% by mass, the deodorant paper itself dissolves with time, so that it becomes difficult to dissolve in water during use, and the deodorizing performance also decreases.
In order to maintain the moisture content of the deodorant paper, it is necessary to seal the deodorant paper after production. In order to suppress the evaporation of moisture in the deodorant paper, the sealed container is preferably a plastic container or bag. Especially, a plastic bag or aluminum bag deposited with aluminum hardly permeates moisture, and the moisture content of the deodorant paper is long. It is preferable because the period is kept constant.

  A deodorant paper according to the present invention was obtained by applying an inorganic deodorant, a water-soluble binder, and a deodorant dispersion containing water or a mixed solvent containing water to the water-soluble paper, and It can manufacture by performing continuously the process of drying water-soluble paper, and making the water content of the water-soluble paper after drying into 5-15 mass%. Here, the reason why the deodorant dispersion application step and the drying step are continuously performed is that, after the deodorant dispersion application step, if the time until drying is long, dissolution of the water-soluble paper proceeds, This is because the strength of the paper is weakened and the solubility in water and the deodorizing property are lowered.

  In the present invention, “continuous” means that the time from the coating step to the drying step is within 20 minutes, preferably within 10 minutes, and more preferably within 5 minutes.

As a specific method for producing a deodorant paper, a deodorant dispersion liquid in which an inorganic deodorant and a water-soluble binder are dispersed in water or a mixed solvent containing water is sprayed, coated, padded, and dipped. For example, there is a method of applying to water-soluble paper. Among these, a coating method is preferable, and gravure printing is particularly preferable. This is because a specific amount of deodorant can be applied to water-soluble paper, and a deodorizing effect is easily obtained.
In the next drying step, the water-soluble paper coated with the deodorant dispersion as described above is dried at a temperature of 115 to 145 ° C. The drying temperature is preferably 120 to 140 ° C. If the drying temperature is within the range of 115 to 145 ° C., the required deodorant paper can be produced without adversely affecting the water-soluble paper and the water-soluble binder. What is necessary is just to adjust drying time so that the moisture content of the water-soluble paper after drying may be 5-15 mass%.

  Water used in the manufacture of deodorant paper or a mixed solvent containing water is a liquid for dispersing an inorganic deodorant and a water-soluble binder and coating the water-soluble paper. Examples of the solvent mixed with water include methanol, ethanol, isopropyl alcohol, n-propyl alcohol, isobutyl alcohol, n-butyl alcohol, tert-butyl alcohol, ethylene glycol monomethyl ether, propylene glycol monomethyl ether, diethylene glycol monomethyl ether, diethylene glycol, Examples include alcohols such as acetone alcohol; ketones such as acetone, methyl ethyl ketone, and methyl isobutyl ketone; esters such as methyl acetate and ethyl acetate; and cyclic ether compounds such as tetrahydrofuran. Considering the dispersibility of the deodorant, the viscosity suitable for processing after dispersion, and the drying speed, water or a mixed solvent of water and alcohol is preferable, and a mixed solvent of water and alcohol is particularly preferable. The mixing ratio (mass ratio) of water and alcohol is preferably 95/5 to 60/40, and more preferably 90/10 to 70/30.

  The solid content concentration of the deodorant dispersion is preferably 5 to 50% by mass, more preferably 7 to 40% by mass, and still more preferably 10 to 30% by mass. If the solid content concentration is in the range of 5 to 50% by mass, the viscosity of the deodorant dispersion is appropriate and can be uniformly applied to water-soluble paper.

There is no particular limitation on the amount of the inorganic deodorant supported on the water-soluble paper. In general, the larger the loading amount, the greater the deodorizing effect, but the amount of water-soluble binder and solvent increases, making it difficult to produce deodorant paper. A preferable loading amount of the inorganic deodorant is 3 to 15 g / m ² , and more preferably 5 to 13 g / m ² . If the carrying amount is in the range of 3 to 15 g / m ² , there is no problem in the strength of the obtained deodorant paper, and a sufficient deodorizing effect can be obtained.

The manufactured deodorant paper may be used after being cut into an appropriate size after the drying step. The size of the deodorant sheet is preferably a 50cm ² ~300cm ^2. If it is this size, it is easy to handle.

  Although this invention is demonstrated more concretely based on an Example and a comparative example, this invention is not limited to this.

1. Evaluation Method (1) Water Content The produced deodorant paper was dried at 105 ° C. for 2 hours, and the weight before and after drying was used to calculate from the following formula.
(W ₁ −W ₂ ) / W ₁ × 100 = Moisture content (%)
[W ₁ : paper weight before drying, W ₂ : paper weight after drying]

(2) Deodorizing performance The deodorizing rate was measured using ammonia and hydrogen sulfide gas, which are part of the components of the urine odor. Specifically, 8 cm × 12 cm of deodorant paper is put in a test bag made of vinyl alcohol polymer film, and 1 L of ammonia gas having a concentration of 100 ppm or hydrogen sulfide gas having a concentration of 20 ppm is injected therein, and 30 minutes later. Using the value measured when the residual gas concentration in the test bag was measured with a gas detector tube and the same test operation with only gas without inserting deodorant paper (hereinafter referred to as `` blank test ''), Calculated from the following equation:
(C ₀ -C ₁ ) / C ₀ × 100 = deodorization rate (%)
[C ₀ : Gas concentration in blank test, C ₁ : Gas concentration when using deodorant paper]

(3) Water solubility The water solubility was determined by measuring the time until decomposition when the deodorant paper was added to water so as not to retain the original shape. Specifically, when 30 cm × 30 cm of deodorant paper was put into 300 mL of water at 20 ° C. and stirred at 300 rpm, the time until no water-soluble paper of about 1 cm × 1 cm or more was visually confirmed was measured. .

2. Production and evaluation of deodorant paper <Example 1>
An inorganic deodorant obtained by mixing aluminum silicate and zinc oxide at a mass ratio of 80/20, polyvinyl alcohol (PVA), isopropyl alcohol, and water were mixed at a mass ratio of 16.7 / 6.7 / 9.9 / 66.7. To prepare a deodorant dispersion. Next, the deodorant dispersion is applied to water-soluble paper made of carboxymethyl cellulose having a thickness of about 0.1 mm, and then dried at 120 ° C. for about 10 seconds within 10 seconds, thereby removing the deodorant paper. Got. The amount of the inorganic deodorant carried was 7.4 g / m ² . The water content, deodorizing performance and water solubility of the obtained deodorant paper were evaluated and listed in Table 2.

<Example 2>
Deodorant paper was produced and evaluated in the same manner as in Example 1 except that the drying temperature was 130 ° C. for about 10 seconds.

<Examples 3 to 6>
Deodorant paper was produced and evaluated in the same manner as in Example 1 except that the inorganic deodorant shown in Table 1 was used.

<Comparative Example 1>
A deodorant paper was produced and evaluated in the same manner as in Example 1 except that the drying temperature was 110 ° C. for about 10 seconds.

<Comparative Examples 2 and 3>
Deodorant paper was produced and evaluated in the same manner as in Example 1 except that the time from coating to drying was changed as shown in Table 1.

<Comparative Examples 4-6>
Deodorant paper was produced and evaluated in the same manner as in Example 1 except that the inorganic deodorant and the water-soluble binder were changed as shown in Table 1.

<Comparative Example 7>
A deodorant paper was produced and evaluated in the same manner as in Example 1 except that an inorganic deodorant was not used.

  The deodorizing paper of the example dissolved quickly in water, and the deodorizing rate of ammonia and hydrogen sulfide, which are components of manure odor, was 90% or more. On the other hand, since the water content of the deodorizing papers of Comparative Examples 1 to 3 is outside the range of the present invention, both the water solubility and the deodorizing property are lowered. Moreover, since Comparative Examples 4-7 do not include the inorganic deodorant of the present invention, a sufficient deodorizing effect cannot be obtained.

  The deodorant paper of the present invention is effective in fields such as deodorization of daily life odor, body odor, manure odor, and garbage odor, and can be used in various fields that require deodorization. For example, in addition to a deodorant for toilets and portable toilets, it can be used as tissue paper, toilet paper, and the like.
