  As the conventional release agent, an alkaline release agent containing a surfactant, a strong alkali component such as sodium silicate and caustic soda, a solvent, ammonia and amines has been used. Such a release agent is a strong alkali having a pH of more than 12, and depending on the building material, there are some materials that are weakly alkaline, such as linoleum, linole tile, rubber tile, marble, and flooring floor (woody system). In some cases, it may have adverse effects such as decolorization and corrosion, and may adversely affect adjacent wall materials and fixtures. In particular, in the case of a wooden floor material, there are adverse effects that are extremely difficult to regenerate, such as discoloration, peeling of the floor material, and floor noise. Therefore, it is necessary to take care by sufficiently curing the peeling work, which is very troublesome.

  In addition, since conventional stripping agents are strong alkalis, the effects on the human body are severe, and there is a peculiar irritating odor, which causes discomfort to workers during work and sometimes makes them feel bad. There was a risk that it would worsen and chemical sensitivity, and there was a problem with its safety. Furthermore, since the stripping waste liquid is also a strong alkali, adverse effects on the environment due to the discharge of the stripping waste liquid, such as an adverse effect on the septic tank, have been pointed out.

  Furthermore, the conventional release agent contains a large amount of a solvent and the like as well as a large amount of a surfactant in order to improve the release performance. Along with this, foaming during use increases, and when collecting waste liquid after peeling with wet vacuum etc., foam pushes up the float, the machine stops and the work is frequently interrupted is there. In addition, when wiping with water, the foam is difficult to disappear and a large amount of residual components remain, causing problems such as the need to increase the number of times of water wiping for recovery, and poor work efficiency. There was also. In addition, since there are many surfactants and the components are likely to remain, there are problems such as slipperiness during work and risk of work.

  As described above, the conventional floor polish remover involves problems such as work and danger when removing the coated floor polish film, and there is a concern that adverse effects on the human body and the environment may occur. It was out.

  Specifically, the release agent of the above-mentioned Patent Document 1 has been improved so that it has a moderate viscosity and does not flow under fixtures between application and recovery of the release agent. Is a problem. Further, the release agent of Patent Document 2 has a pH of 7.0 to 9.5, but leaves a problem in peelability and foaming. Moreover, although the release agent of the said patent document 3 consists of a specific solvent and ethanolamine, it leaves a problem in an odor, peelability, foaming, etc. Furthermore, the release agent of Patent Document 4 uses a specific solvent and amine, but leaves problems in foaming, slipping property, wastewater recovery, and the like.

  In recent years, the performance demanded of floor polish has been increasing, and in order to improve the durability in particular, an even stronger floor polish has been developed and used. A stronger type of release agent for removing such a strong floor polish film has also been developed, but only development in the direction of increasing the surfactant or making it stronger alkali has been carried out. In fact, the problem with the release agent as described above has not been solved.

  The present invention has been made in view of such circumstances, has a peeling force equivalent to that of a conventional alkaline release agent, has little irritating odor, and is high with respect to slipping that causes a fall accident during work. It is an object of the present invention to provide a release agent composition that has resistance, has less foaming, and is excellent in the reattachment of cleaning wastewater and the prevention of recontamination.

  In order to achieve the above-mentioned object, the release agent composition of the present invention contains fatty acids, amines, solvents, and α-hydroxy acids as main components, and is water-soluble or soluble so that they can be diluted with water. The gist is that it exists in a water-dispersed state and the pH is adjusted to neutral or alkaline.

  In addition, the method for producing the release agent composition of the present invention contains fatty acids, amines, solvents, and α-hydroxy acids as main components, and is water-soluble or water-dispersed so that these can be diluted with water. The gist of the present invention is to contact a porous adsorbent with a concentration-type exfoliant release agent composition having a pH of neutral to alkaline.

  The present inventor has conducted various researches on the improvement of the peeling performance by the components of the release agent composition, the influence on the human body and the environment, flooring materials and adjacent fixtures, and environmental safety, and the same peelability as before. The present inventors have found a release agent composition that has a small influence on the human body and environment, adjacent fixtures and flooring, and has reached the present invention.

  That is, the release agent composition of the present invention has a strong release property equivalent to that of a conventional strong alkali release agent, and has improved work efficiency and safety by reducing the irritating odor. In other words, since the pH can be adjusted arbitrarily in the neutral or alkaline region, adverse effects on flooring materials and surrounding fixtures are reduced, the operator's rough hands are reduced, and the number of water wipes after work is reduced. In addition, the environmental load due to the separated drainage after work can be reduced. In addition, since the foaming is very small, there is no interruption of the operation due to the stop of the apparatus as in the prior art, the number of wiping operations is reduced, and the cleaning waste liquid after peeling can be processed in a short time. In addition, since the slipperiness during work is low, falling accidents are reduced and work safety is dramatically improved. In addition, highly stable concentration is possible, the container can be made smaller or smaller, and the labor and storage space can be saved, and the use of resources for containers such as iron and plastic can be reduced.

  Moreover, the manufacturing method of the release agent composition of the present invention makes it possible to thoroughly reduce the irritating odor, and a release agent composition with very little irritating odor can be obtained. With such a release agent composition, the discomfort of the worker during the work is greatly reduced, and the trouble around the workplace is also greatly reduced.

  Next, the best mode for carrying out the present invention will be described in detail.

  The release agent composition of the present invention contains fatty acids, amines, solvents, and α-hydroxy acids as main components. In the present invention, the main component is a main active ingredient that can contribute as a release agent.

  The fatty acids improve the permeability of the release agent composition, penetrate into the scratches on the floor surface, and peel off the floor polish component that has entered the scratches. Moreover, foaming is reduced while imparting the high releasability of the release agent composition. In addition, it increases the solubility of hardly soluble components (for example, solvents such as benzyl alcohol) constituting the release agent composition, and contributes to obtaining a water-soluble or water-dispersed state.

  As the fatty acids, saturated fatty acids or unsaturated fatty acids can be used and are not particularly limited. For example, examples of saturated fatty acids include caproic acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, and coconut fatty acid. Examples of the unsaturated fatty acid include oleic acid, beef tallow fatty acid, linoleic acid, linolenic acid, erucic acid, soybean fatty acid and the like. These may be used alone or in combination of two or more.

  In particular, the fatty acid is preferably selected from at least one of lauric acid, myristic acid, palmitic acid, oleic acid, stearic acid, and linoleic acid. These fatty acids have little odor and excellent compatibility with the above-mentioned other components, and easily generate fatty acid amine salts by reaction with amines, while obtaining solubility and stability of other components. , Which contributes to the improvement of the peeling force.

  The fatty acid including at least one of the lauric acid, myristic acid, palmitic acid, oleic acid, stearic acid, and linoleic acid is preferably contained in an amount of 0.1 to 10% by weight in the main component. More preferably, it is 5 wt% to 10 wt%. This is because if it is less than 0.1% by weight, it does not contribute to penetrating power, and if it exceeds 10% by weight, it takes time to dissolve it.

  The amines impart excellent release properties to the release agent composition.

  The amines are not particularly limited. (Mono, di, tri) isopropanolamine, (mono, di, tri) ethanolamine, morpholine derivatives, N, N dimethylethanolamine, N-β-aminoethylethanol Examples include amino alcohol derivatives such as amines. These may be used alone or in combination of two or more.

  Among these, from the viewpoint of low irritating odor and high safety, in particular, among (mono, di, tri) isopropanolamine, (mono, di, tri) ethanolamine, aminoethoxyethanol, amino alcohol derivatives, etc. At least one of them is preferably used.

  Amines including the above (mono, di, tri) isopanolamine, (mono, di, tri) ethanolamine, aminoethoxyethanol and amino alcohol derivatives are contained in the main component in an amount of 1 to 70% by weight. It is preferable to contain 5% by weight to 50% by weight. This is because if it is less than 1% by weight, it does not contribute to the peelability, whereas if it exceeds 70% by weight, there is a high risk of causing rough hands.

  The above-mentioned solvents dissolve the wax and resin components of the coating to be peeled to ensure releasability.

  The solvents are not particularly limited, but considering safety, for example, (mono, di, tri) oxyalkylene glycol derivatives, lactic acid esters, glycol ethers, N-methyl-2-pyrrolidone, Alcohols, polyhydric alcohols, 1,3-dimethyl-2-imidazolidine and the like can be used. In addition, for example, cellosolve solvents such as methyl, ethyl, butyl, and phenyl, carbitol solvents such as methyl, ethyl, and butyl, 3-methyl-3-methoxybutanol, benzyl alcohol, and benzyl alcohol are mixed with 1 to 2 mol of ethylene oxide. An added derivative, hexylene glycol, or the like can be used. These may be used alone or in combination of two or more.

  Among these, benzyl alcohol, derivatives obtained by adding 1 to 2 moles of ethylene oxide to benzyl alcohol, glycol ethers, dialkyl glycol ethers, 3-methyl-3methoxybutanol, 1,3-dimethyl-2 are particularly preferable. -At least one of imidazolidinone and dihydric alcohols can be used. This is because these solvents are relatively easy to obtain, have high safety, have little odor, and have moderate resin dissolving power.

  These solvents are preferably contained in the main component in an amount of 1% by weight to 80% by weight, and more preferably 5% by weight to 70% by weight. This is because if it is less than 1% by weight, it does not contribute to the peelability, whereas if it exceeds 80% by weight, there is a concern about the influence on the adhesive for fixing the flooring.

  The α-hydroxy acids enable pH adjustment in a stable state where the components of the release agent composition are not separated. Thereby, it becomes possible to adjust pH arbitrarily in neutral-alkaline range. For example, if the pH is an alkaline side, the pH can be adjusted to be weakly alkaline or neutral by containing these α-hydroxy acids. Conversely, if the pH is an acidic side, the amount of the amines added is increased. Thus, the pH can be adjusted to neutrality or weak alkalinity. In particular, when an α-hydroxy acid is added to an alkali and the pH is adjusted to be weakly alkaline or neutral, the solution stability and the peeling performance can be further improved. Here, the neutral to alkaline range of pH specifically refers to a range of pH 6 to 12.

  Examples of the α-hydroxy acids include citric acid, glycolic acid, malic acid, lactic acid, and tartaric acid. Among these, citric acid and malic acid are preferable, and glycolic acid is particularly preferable. This is because these α-hydroxy acids are relatively easily available, have high safety, have little odor, and are excellent in solubility in a release agent solution.

  The release agent composition of the present invention dissolves the wax and resin content of the coating to be peeled with the above solvents, and the fatty acid and amines are mixed to produce a cleaning component with less foaming and dissolved. The removed resin is washed away. And the pH adjustment of the said washing | cleaning component is enabled by (alpha) -hydroxy acids, and adjusting to appropriate pH according to the kind and application of the coating of peeling object is performed.

  The release agent composition of the present invention contains 10% by weight or more of the total combination of the main components including the fatty acids, amines, solvents, and α-hydroxy acids, and these can be diluted with water. It exists in a water-soluble or water-dispersed state. In this way, when using the release agent composition, it can be used as a stock solution or diluted up to about 50 times with water depending on the state of dirt.

  The release agent composition of the present invention can further contain at least one of acetylene glycol derivatives, aliphatic diol derivatives, polyvinylpyrrolidones, cyclodextrins, and N-alkylpyrrolidones as a main component. .

  All of these cling to the peeled resin, making it difficult to slip and making it easier to recover the stripped waste liquid. These may be used alone or in combination of two or more. These are preferably contained in an amount of about 0.01 to 10% by weight, more preferably 0.1 to 5% by weight, based on the main component. If the amount is less than 0.01% by weight, the effect of making it difficult to slip or facilitating the recovery of the stripping waste liquid is not sufficient, and if it exceeds 10% by weight, the solubility is poor and foaming is increased.

  The above-mentioned acetylene glycol derivatives adhere to the peeled resin and make it easy to collect the stripped waste liquid, reduce the dynamic surface tension and quickly adsorb to the interface, improve wettability and improve cleaning power. Increases defoaming properties. Examples of the acetylene glycol derivatives include those obtained by adding ethylene oxide to 2,4,7,9-tetramethyl-5-densi-4,7 diol and the like.

  The above polyvinylpyrrolidone not only maintains the stability of the release agent solution, but also prevents the drying by preventing the volatilization of volatile components in the release agent, thereby preventing the drying and stabilizing the work efficiency. Adsorbs to the minute and plays a role in preventing re-adhesion and re-contamination. This effect improves the recovery of sewage and makes it difficult to slip.

  The polyvinyl pyrrolidone preferably has a K value of 10 to 130, more preferably 20 to 100. This is because when the polyvinyl pyrrolidone has a K value outside the above range, the solubility in the release agent solution is poor.

  The cyclodextrin not only maintains the stability of the stripper solution, but also suppresses the volatilization of the volatile components in the stripper to prevent drying and stabilize the work efficiency, and the dissolved floor polish resin film Adsorbs to the minute and plays a role in preventing re-adhesion and re-contamination. In addition, by including a causative substance of the irritating odor, the irritating odor can be suppressed. As the cyclodextrins, those having high water solubility and those that are soluble in a solvent are preferably used. Specifically, for example, cyclic oligosaccharides obtained by allowing an enzyme to act on starch, and glucose is a structural unit. Ordinary ring, macrocycle, intramolecular branched type such as glucose (6-type), 7 (β-type), 8 (γ-type), etc. and enzyme decoration, chemical decoration, special Decorated ones can be used. What can be suitably used is easily soluble in water or a solvent, and examples thereof include cyclodextrins subjected to chemical decoration or enzyme decoration.

  The N-alkylpyrrolidones are adsorbed on the dissolved resin film of the floor polish, contribute to prevention of re-adhesion and re-contamination, make it difficult to slip, and facilitate the recovery of the stripping waste liquid. As the N-alkylpyrrolidone, N-octyl or N-dodecylpyrrolidone is particularly preferably used. This is because these are relatively excellent in solubility, less odor, and high safety.

  The aliphatic diol derivatives adhere to the peeled resin and facilitate the recovery of the stripping waste liquid, and quickly adsorb to the interface to limit wettability and foaming.

  The release agent composition of the present invention can further contain perfluoroalkyl phosphate esters as a main component.

  The perfluoroalkyl phosphates promote the penetration of the release agent, penetrate deeply into the scratches on the floor surface, and peel to the floor polish resin that has entered the scratches. As the perfluoroalkyl phosphate esters, those that are water-soluble or highly soluble in a solvent can be preferably used. Specifically, for example, perfluorophosphate diester salts can be used, The salt is preferably an amine salt because of its excellent solubility and compatibility with water and solvents.

    The release agent composition of the present invention can further contain a solubilizer as a main component.

  The above-mentioned solubilizer can make a water-insoluble component water-soluble, enhances the stability of the release agent composition, suppresses separation of the component, and maintains quality and performance for a long period of time. The solubilizer is not particularly limited, and for example, sodium metaxylene sulfonate or sodium paratoluene sulfonate can be suitably used. More preferably, sodium metaxylene sulfonate is used because of its high compatibility and stability with the peeling agent component.

    The release agent composition of the present invention can further contain an aldehyde adsorbent as a main component.

  The aldehyde adsorbent is a deodorant, which eliminates an irritating odor and improves workability and work safety. The aldehyde adsorbent, for example, even when benzyl alcohol by-produces aldehydes such as benzaldehyde and acetaldehyde by a chemical reaction such as a chemical reaction in a long-term solution or an oxidation reaction at the time of volatilization. Prevent dissipating during work. In particular, since the odor of the above solvents is effectively suppressed, it contributes to securing the peeling performance by containing an appropriate amount of the solvents.

  As the aldehyde adsorbent, for example, urea, dipotassium phosphate, sodium sulfite, and those having a functional group such as a sulfonic acid group, an aldehyde group, and a carboxyl group can be suitably used.

  The release agent composition of the present invention is optionally builders, alcohols, glycol ethers, other solvents, fragrances, colorants, solubilizers, surfactants, antibacterial agents, thickeners, etc. It is possible to contain these components.

  The release agent composition of the present invention can be prepared by sequentially adding each component together with water to a container while stirring, and continuing stirring for several hours.

  Such a release agent composition has a strong release property equivalent to that of a conventional strong alkaline release agent, and has improved workability and safety by reducing the irritating odor. In other words, since the pH can be adjusted arbitrarily in the neutral or alkaline region, adverse effects on flooring materials and surrounding fixtures are reduced, the operator's rough hands are reduced, and the number of water wipes after work is reduced. In addition, the environmental load due to the separated drainage after work can be reduced. Further, since the foaming is very small, there is no interruption of the operation due to the stop of the apparatus as in the prior art, the number of wiping operations is reduced, and the cleaning waste liquid after peeling can be processed in a short time. In addition, since the slipperiness during work is low, falling accidents are reduced and work safety is dramatically improved. In addition, highly stable concentration is possible, the container can be made smaller or smaller, and the labor and storage space can be saved, and the use of resources for containers such as iron and plastic can be reduced.

  Moreover, the release agent composition of this invention can remove the impurity in a composition, and can reduce an odor further by making it contact with a porous adsorbent.

  As the porous adsorbent, for example, at least one of activated carbon, bamboo charcoal, charcoal, silicon dioxide, activated alumina, silica gel, zeolite, clay, clay, and the like can be used. These can be used alone, but may be used in combination depending on the intended processing component.

  Specifically, 1 to 10% by weight of a porous adsorbent is added to the release agent composition at room temperature and normal pressure, and after stirring for several hours, the treatment agent is removed using a filter press or a microfiltration device. Alternatively, it is possible to reduce the irritating odor by filling the column with a treatment agent and filtering the release agent composition of the present invention through the column.

  According to this method for producing a release agent composition, it is possible to thoroughly reduce the irritating odor, and a release agent composition with extremely little irritating odor can be obtained. With such a release agent composition, the discomfort of the worker during the work is greatly reduced, and the trouble around the workplace is also greatly reduced.

  The treatment with such a porous adsorbent is performed immediately before filling a container such as a can, and the treated material is immediately sealed and sealed. By doing so, the release agent in a state where impurities and aldehydes are adsorbed and removed is hermetically sealed in the container, so that an irritating odor component is less likely to be generated before opening.

  Next, examples will be described.

In addition, for the actual floor test, a total of 5 layers of resin wax “Fablas” manufactured by Suisho Oil Chemical Co., Ltd. were applied, and a black pad was attached to the polisher to recover the slipping degree and sewage. Was evaluated.

  The test method of the test item is as follows.

  A comparative test was conducted in accordance with JFPA Standard-205 and the release agent peeling performance test method using the above-mentioned JFPA Standard-201 and standard polish formulation. In this test, the release agent for the polish obtained from the Examples and Comparative Examples was evaluated for the release performance by using 5 times, 10 times, 15 times, 20 times and 30 times diluted with water in advance. .

  In addition, the foaming property test of the release agent is in accordance with JFPA standard-202, the foaming property test method for floor detergents, and the defoaming test is JFPA standard-203, the foaming property testing method of floor detergents. It carried out according to. However, the evaluation was performed based on the height of the foam (ml).

  The influence test on the base material was made by using Tajima Co., Ltd., Linoleum tile, trade name, Marmolium, 3 ml of a 5 times diluted solution of a polish remover and dripping on the tile, and covering with a cover glass. One hour later, the diluted solution was wiped off, and the degree of influence such as discoloration was determined.

  Moreover, about the slip degree and the recoverability of sewage, Example A and B evaluated by 15 time dilution liquid, and all of E and the comparative example evaluated using 5 time dilution liquid.

  The test results are shown in Table 4 below.
