Description

Non-hydrochloric acid type urinary calaulus remover composition and Liquid type urinary calaulus remover containing the same}

The present invention relates to a non-hydrochloric acid-based liquid urethane remover, and a composition used in the preparation thereof.

In the toilet drain pipe, in particular, the drain pipe of the men's toilet, a scale called urinary stone adhered to a mixture of calcium-based compounds or organic substances produced by the decomposition of urine is generated, and the flow of urine and washing water is deteriorated. In severe cases, the drain pipe is blocked, and the toilet becomes unusable. In addition, organic matter in the stone is decayed by bacteria to generate an odor. The odor of men's toilets is a mixture of odors caused by decay of organic matter and ammonia generated by decomposition of urine.

The odor generated from the toilet and the drain pipe is the main cause of the odor in the toilet, and this is the root cause of urea and various bacteria, which are sediment fixed to the toilet and the drain pipe. The odor-causing bacteria grow and multiply around the clock in toilets rich in water, air, temperature and nutrients. It is a hotbed of bacteria living in sediments such as toilet bowls and pipes in toilets, and since the number of bacteria doubles every 20 minutes, it is necessary to continuously clean, sterilize and disinfect toilets and pipes in toilets using an effective urethane remover. It can remove clogging and odors caused by. Particularly, in the drain pipe where water goes down in the toilet, scales like uneven stones are deposited over a long period of time, preventing the smooth flow of water. As the scale increases, the flow of water slows down, and if appropriate measures are not taken, the toilet may become clogged or a disgusting odor may flow back.

Conventionally, in order to solve the problem of clogging a toilet, a lot of cost is wasted by replacing a toilet bowl, constructing a drain pipe, or continuously removing scale or treating various chemicals. In addition, even if such a construction is performed, the effect is temporary, so the scale is generated again and the cost is increased. In addition, in order to remove odors, management costs are increased by continuously using fragrances or carcinogens such as naphthalene, or liquid chemicals such as hydrochloric acid, nitric acid and lactose (sodium hypochlorite).

In addition, as a conventional method for preventing scale of a toilet drain pipe, a method of injecting a drug in the middle of a washing water pipe and a method of injecting a drug molded into a spherical shape into a toilet of a men's toilet have been put into practice. As drugs used in these methods, various proposals have been made to contain surfactants, disinfectants and fragrances.

For example, a deodorant cleaner for a flush toilet was developed by melt-mixing a surfactant, an ion sequestering agent, a fragrance, etc. with polyethylene glycol or polypropylene glycol and a fragrance, and injection molding.

However, all of the existing methods of removing and preventing uneven stone as described above are not sufficient to prevent the scale from sticking to the toilet drain pipe, or, even if the sticking preventing effect is present, problems such as expensive or heavy work, or adversely affecting the septic tank. There is a problem that corrosiveness to iron and copper metals and toxic gases are generated due to the chemical action of chemicals.

Korean Patent Application Publication No. 10-2014-0063822 (published on May 27, 2014)

The inventors of the present invention have completed the present invention by knowing the optimum composition and composition ratio of the urethane remover that does not generate toxic gas while preventing the corrosion of iron-based and copper-based metals, which is a problem of the existing urethane remover. That is, the present invention is to provide a urine stone removal agent composition and a liquid urine stone removal agent prepared by using the same.

The present invention for solving the above problems relates to a non-hydrochloric acid-based urate removal agent composition, inorganic acids, organic acids, metal corrosion inhibitors, inorganic salts, permeable emulsifiers, water softener and water. Includes.

In addition, an object of the present invention relates to a non-hydrochloric acid-based urethane removing agent, and does not include the hydrochloric acid-based urethane-removing component.

Since the urinary stone remover prepared with the composition of the present invention is liquid and does not use chlorine-based components, it is possible to minimize or prevent corrosion of metal products such as iron-based, copper-based, etc. that constitute piping installed in toilets, etc., and chlorine-based It is possible to provide an urethane remover capable of effectively removing urethane without generating toxic gases such as chloric acid gas, which are harmful to the human body caused by the component.

Hereinafter, the present invention will be described in more detail.

The non-chlorine-based decontamination agent composition (hereinafter referred to as'composition') of the present invention contains inorganic acids, organic acids, metal corrosion inhibitors, inorganic salts, penetration and emulsifiers, water softeners and water. Includes.

Among the components of the composition of the present invention, the inorganic acid plays a role of dissolving calcium in the urethane component, and may include at least one selected from orthophosphoric acid and sulfamic acid, preferably orthophosphoric acid. And two types of sulfamic acid may be used in combination.

And, the content of the inorganic acid in the composition of the present invention may include 15 to 20% by weight, preferably 16 to 19% by weight, more preferably 16.5 to 18.5% by weight of the total weight of the composition. At this time, if the inorganic acid content is less than 15% by weight, there may be a problem of lowering the reaction rate of the urethane with calcium, and if it exceeds 20% by weight, there may be a problem that the corrosiveness of the metal increases rapidly, so it is preferable to use it within the above range.

Next, among the components of the composition of the present invention, the organic acid maintains the reactivity with calcium of the urethane and serves to suppress the increase in metal corrosiveness caused by the acid, rather than simply making the urethane remover with only inorganic acid. It may include at least one selected from acetic acid, oxalic acid and glycolic acid, and preferably at least one selected from citric acid and glycolic acid.

In addition, the content of the organic acid in the composition of the present invention may include 2.0 to 5.0% by weight, preferably 2.5 to 5.0% by weight, more preferably 2.5 to 4.0% by weight of the total weight of the composition. At this time, if the organic acid content is less than 2.0% by weight, there may be a problem that the dissolution reaction rate with the calcium component of the urethane is lowered, and even if it is used in excess of 5.0% by weight, the calcium dissolution rate of the urethane does not increase any more. Since there may be a problem that the cost performance is deteriorated, it is recommended to use it within the above range.

Next, among the components of the composition of the present invention, the metal corrosion inhibitor serves to prevent corrosion of metal products such as iron-based metals and copper-based metals, and 1.2.3-Triazole, 1.2.4. -Triazole (1.2.4-Triazole), 1.2.3-Benzotriazole, Tolytriazole, Mercaptobenzothiazole, Methylenephosphonic acid acid), 1-hydroxyethane-1,1-diphosphonic acid, 3-heptyl-5-amino-1,2,4-triazole (3 -heptyl-5-amino-1,2,4-triazole) and 2-phosphonobutane, 1-2,4-tricarboxylic acid (2-phosphonobutane-1,2,4-tricarboxylic acid) It may include the above, and preferably may include at least one selected from 1.2.3-benzotriazole, tolitriazole, and 1-hydroxyethane-1,1-diphosphonic acid.

And, the content of the metal corrosion inhibitor in the composition of the present invention may include 1 to 5% by weight, preferably 1.5 to 4.2% by weight, more preferably 1.8 to 3.8% by weight of the total weight of the composition. At this time, if the content of the metal corrosion inhibitor is less than 1% by weight, the amount of the corrosion inhibitor may be insignificant, and if it exceeds 5% by weight, it is not dissolved due to excessive use, and there is a problem that a precipitate is generated. Therefore, it is better to use it within the above range.

Next, among the components of the composition of the present invention, the inorganic salt serves to enhance the removal ability by enhancing the solubility of urethane, and the inorganic salt includes at least one selected from sodium chloride, acid sodium pyrophosphate, and magnesium chloride. It may, and preferably contain at least one selected from acidic sodium pyrophosphate and magnesium chloride.

And, the content of the inorganic salt in the composition of the present invention may include 8 to 13% by weight, preferably 9.0 to 12.0% by weight, more preferably 9.5 to 11.5% by weight of the total weight of the composition. At this time, if the content of the inorganic salt is less than 8% by weight, there may be a problem of lowering the solubility of the urethane, and if it exceeds 13% by weight, there may be a problem that the undissolved inorganic salt remains in the liquid urethane remover and a precipitate may be generated. It is better to use it within the range.

Next, in the composition components of the present invention, the permeable emulsifier serves to increase the peeling efficiency of the deposited urethane, and the permeable emulsifier is polyoxyethylene lauryl ether, polyoxyethylene oleyl ether ( Polyoxyethylene oleyl ether), polyoxyethylene tridecyl ether, polyoxyethylene stearyl ether, and linear alkylbenzene sulphonate. Preferably, it may include at least one selected from polyoxyethylene lauryl ether and polyoxyethylene oleyl ether.

In addition, the content of the permeable emulsifier in the composition of the present invention may include 1 to 2% by weight, preferably 1.2 to 2.0% by weight, more preferably 1.2 to 1.8% by weight of the total weight of the composition. At this time, if the content of the permeable emulsifier is less than 1% by weight, there may be a problem that the peeling effect of the deposited urethane is rapidly deteriorated, and if it exceeds 2% by weight, there is no significant difference in the corrosion resistance and urethane removal rate. When washing with water, there may be a problem that excessive bubbles are generated by residual chemicals, so it is recommended to use within the above range.

Next, among the components of the composition of the present invention, the water softener serves to remove metallic substances in water and prevent the formation of precipitates in the product.Ethylenediamineacetic acid sodium salt, nitrilotriacetic solution It may contain at least one selected from seed sodium salt (Nitrilotriacetic acid sodium salt) and acrylate polymer, and preferably at least one selected from ethylenediamine acetic acid sodium salt and acrylate polymer. I can.

And, the content of the water softener in the composition of the present invention may include 0.5 to 1.0% by weight, preferably 0.65 to 0.95% by weight, more preferably 0.70 to 0.90% by weight of the total weight of the composition. At this time, if the content of the light water emulsifier is less than 0.5% by weight, the amount of the light-water emulsifier is too small, so that the sufficient effect of removing metal ions may be insufficient. Good to use.

In addition, the composition of the present invention includes an inorganic acid, an organic acid, a metal corrosion inhibitor, an inorganic salt, a penetrating emulsifier, a water softener, and water in the balance of the total weight of the composition.

The non-hydrochloric acid-based urate removal agent of the present invention prepared by mixing and stirring the composition of the present invention described above is a liquid type, has a pH of 1 to 2, and may have a viscosity of 0.2 to 2.5 cps at 25°C.

In the results of measuring the corrosiveness and urinary stone removal rate in Table 2, it can be seen that in Examples 1 to 10, the corrosiveness to the iron-based metal is very low, and there is an effect of the urethane stone removal rate of 99.0% or more.

On the other hand, in the case of Comparative Example 1, which was used as 14% by weight of which the inorganic acid content was less than 15% by weight, as compared to Example 1, the corrosion property was low, but there was a problem that the urethane removal rate was greatly reduced, and the inorganic acid content exceeded 20% by weight. In the case of Comparative Example 2 used at 21% by weight, as compared with Examples 1 and 2 (19% by weight), the urethane removal rate slightly increased, but there was a problem that the corrosiveness of the iron-based metal was rapidly increased by two or more times. I could confirm.

In addition, in the case of Comparative Example 3 in which the organic acid was used in an amount of 6.0% by weight exceeding 5.0% by weight, compared with Example 1 (2.9% by weight) and Example 3 (5.0% by weight), the effect of improving iron-based corrosion resistance was insufficient. .

There was a problem, because the solubility of the urine stone in the urine stone removal agent was lowered. And, in the case of Comparative Example 7 using more than 13% by weight of the inorganic salt, as compared with Example 1 (10.2% by weight) and Example 7 (12.5% by weight), the urethane removal rate is very excellent, but the precipitation occurs during long-term storage.
