Description

  The present invention relates to a sheet-like or mat-like cleaner that can remove foreign matters such as dirt, water, sap, iron powder and the like attached to a surface to be treated such as an automobile paint film surface and a plastic surface. More specifically, the present invention relates to a sheet-like or mat-like cleaner that can clean the treated surface by lightly rubbing the wet treated surface.

  A physical method and a chemical method are often employed as a method for removing iron powder stains adhering to or sticking to the surface to be treated such as the surface of the coating film.

  The method for physically removing iron dust stains is to wet with water or a specific auxiliary agent, and put a clay lump or clay-like composition lump of a size that can be grasped by the operator by hand on the wet surface to be treated. A method of taking in iron powder stains or the like into the clay lump or clay-like composition lump by pressing or rubbing the surface to be treated with the clay lump or clay-like composition lump is performed.

  Various clay-like compositions for carrying out this physical method have been proposed. One of them is a clay-like cleaner made of a clay-like composition mainly composed of polybutene (see, for example, Patent Document 1). Also, a plastic resin obtained by dispersing alumina or talc in a liquid polymer (for example, see Patent Document 2), a material in which abrasive fine particles are kneaded into a material having room temperature plasticity (for example, see Patent Document 3) In addition, a mixture of an irregularly shaped cube or plane, mica, aqueous silicon and clay (for example, see Patent Document 4) has been proposed. Furthermore, it has also been proposed to perform work by attaching a clay-like polishing member to a polishing machine (see, for example, Patent Document 5). Furthermore, a cleaning material for an automobile body in which a clay layer having a thickness of 2 to 10 mm is provided on one surface of a foamed resin molded body has been proposed (see, for example, Patent Document 6).

As a method for chemically removing iron powder stains or the like, an iron powder stain remover that dissolves or chelates iron powder with an acid or a salt thereof (for example, Patent Document 7, Patent Document 8, Patent Document) 9) is proposed.
Japanese Patent No. 3893501 JP-A-9-207070 Japanese Patent Laid-Open No. 10-237427 JP 2001-302329 A Japanese Patent Laid-Open No. 11-267976 JP 2003-154318 A Japanese Patent Laid-Open No. 10-245597 JP 2006-182932 A JP 7-216395 A

  Among the above-mentioned methods, the method using a clay lump or clay-like composition lump is used by an operator to hold the clay lump or clay-like composition lump by hand and press it against the surface to be treated such as a coating film. It requires labor and labor such as rubbing and fine work while adjusting the shape, and the pressing force of the clay lump and clay-like composition lump applied to the coating surface is uniform. In addition, it is difficult to obtain a uniform finished state over the entire surface to be treated because clay lumps and clay-like rough lumps are not familiar with parts having complicated shapes such as wheels and bumpers. There was a problem.

  On the other hand, in the method of chemically treating iron powder stains, there is a problem that the coating gloss, rubber, metal parts, etc. may be attacked by the iron dust stain remover and their surface gloss or surface roughness may be impaired. there were.

  The present invention has been made in view of the above problems and situations, and it is possible to physically remove iron powder dirt, water, sap, and the like adhering to or sticking to a surface to be treated such as a coating film using a clay-like composition. It is possible to finish the entire surface to be processed well, including parts with complicated shapes such as wheels and bumpers, even though the labor and labor required for the work are reduced. In addition, an object is to provide a sheet-like or mat-like cleaner having excellent handling properties.

  Another object of the present invention is to provide a sheet-like or mat-like cleaner that can be used by being mounted on a polishing machine or the like.

  A sheet-like or mat-like cleaner according to the present invention contains an oil component in a flexible sheet-like or mat-like base material having an internal space communicating with the outside, such as a fiber material such as a nonwoven fabric or cloth, or a sponge material, and A clay-like composition that undergoes plastic deformation is held.

  In the above, “sheet-like or mat-like” is a term used to appropriately express the degree of thickness of the substrate, and “sheet-like” refers to a state in which the thickness is relatively thin. "Shape" refers to a state in which the thickness is relatively thick compared to the sheet shape. In addition, the “clay-like composition” includes not only a single type of resin or a mixture of different types of resins, but also solids and oil components to be mixed with these resins for an increase or for other purposes. The composition contains, and further includes inorganic clay existing in the natural formation.

  The sheet-like or mat-like cleaner of the present invention comprises a flexible sheet-like or mat-like base material having an internal void communicating with the outside, and a clay-like composition containing an oil component and plastically deformed. . When the operator can move this by hand on a wet surface to be treated such as a paint film, the iron powder stains adhering to or sticking to the surface to be treated are removed from the surface to be treated. Incorporated into the composition or substrate. In this case, in the case where the clay-like composition is held only on the surface of the base material, it is taken into the composition held on the surface of the base material or the internal voids of the base material, and the composition becomes the surface of the base material. In addition to being held not only in the internal voids of the substrate, but also in the composition held on the surface of the substrate and the internal voids of the substrate. In such a cleaning process of the surface to be processed, a flexible sheet-like or mat-like base material is useful for wiping off the dirt on the surface to be processed, and the clay-like composition held on the base material is covered. It helps to remove the so-called persistent stains on the treated surface.

  In addition, since the base material has flexibility and the composition held on the base material has a clay shape that undergoes plastic deformation, the cleaner is also applied to parts having complicated shapes such as automobile wheels and bumpers. Is familiar and easy to touch. Therefore, it is possible to finish the entire surface to be processed well and easily including the portion having such a complicated shape. In addition, since the cleaner is in the form of a flexible sheet or mat, not only the handling of the conventional clay lumps and clay-like composition lumps described at the beginning is greatly improved. When the cleaner is moved on the surface to be processed, there is an advantage that the pressing force of the cleaner is uniformly applied to the surface to be processed and the entire surface to be processed is easily finished uniformly.

  The sheet-like or mat-like cleaner of the present invention is a sheet-like or mat-like having a thickness of 1 to 20 mm, and the weight of the composition held on the substrate is the weight of the substrate. It is equivalent or more and the said composition contains the 1 type (s) or 2 or more types of filler chosen from inorganic type powder, organic type powder, and a fibrous material. In the present invention, if the base material having a thickness of 1 to 10 mm is classified into the concept of “sheet shape”, the base material having a thickness of 10 to 20 mm is assumed to be the concept of “matt shape”. Can be classified. And if it is a sheet form, an operation | work puts a hand on the said cleaner put on the to-be-processed surface, and can be moved to arbitrary directions on a to-be-processed surface. In the case of a mat shape, an operator can place his / her hand on the cleaner placed on the surface to be processed, or can be moved in any direction on the surface to be processed by grasping the cleaner by hand. it can.

  If the thickness of the substrate is less than 1 mm, the amount of the clay-like composition retained becomes too small, and there is a possibility that iron powder stains and the like cannot be sufficiently removed. In addition, the bending strength of the base material becomes too low, and when the hand is put on and rubs the surface to be processed, the cleaner may be bent to reduce workability. On the other hand, if the thickness of the base material is greater than 20 mm, when the base material is impregnated with a clay-like composition, it is difficult to become familiar with the work surface when it is applied to a part having a complicated shape. There is a high risk of contact. When the thickness of the substrate is 1 to 20 mm in the form of a sheet or mat, the entire retained composition can be efficiently used to take up iron powder stains and the like, and good usability can be obtained.

  In this invention, the clay-like composition contains one or more fillers selected from inorganic powders, organic powders, and fibrous materials.

  In the sheet-like or mat-like cleaner according to the present invention, it is desirable that the clay-like composition is impregnated in the substrate and held on the surface of the substrate. A sheet-like or mat-like cleaner having this configuration can be easily obtained through a simple and simple process in which the substrate is dipped into a composition in which the composition is uniformly dissolved in a solvent, and then the solvent is removed by evaporation. Therefore, there is an advantage that the cleaner can be manufactured easily and inexpensively.

  The clay-like composition is preferably a polybutene resin. Polybutene resin is used as a non-drying putty etc. in building sealing materials, and its plasticity and viscosity are very similar to clay. Therefore, when the cleaner, which is made by holding or impregnating a polybutene resin on a flexible sheet-like base material, is placed on a wet surface to be treated and slid by hand, it is held on the base material and becomes clay-like. In addition to helping to remove and remove iron powder dirt adhering to or sticking to the surface of the paint film, the polybutene resin presenting It is difficult to cause a situation such as remaining on the surface to be processed.

In the case where the clay-like composition is an inorganic clay existing in a natural formation, the particle size is desirably 0.1 to 30 μm. If the particle size of the inorganic clay in the natural layer is less than 0.1 μm, the iron powder stains, water stains, sap, etc. adhering to or sticking to the surface to be treated such as the paint film are clay-like composition Hard to be physically removed by objects. On the other hand, if the particle system is larger than 30 μm, the particle system is too large to be held on the substrate. When the particle size is 0.1 to 30 μm, the viscosity is well maintained on the base material, and iron powder stains, water stains, sap, etc. adhering to or sticking to the surface to be treated are easily physically removed. Become.
The clay-like composition may contain a polyisobutylene resin in addition to the polybutene resin. Such a clay-like composition is described as a clay-like cleaner in Patent Document 1 listed at the beginning. Therefore, the sheet-like or mat-like cleaner having this structure can be easily obtained by dipping the base material in a clay-type cleaner proposed in Patent Document 1 in a solvent and then evaporating and removing the solvent. Is possible.

  In the present invention, the clay-like composition preferably contains castor oil as the oil component in addition to the polybutene resin, the polyisobutylene resin, and the filler. The castor oil as the oil component is desirably contained in an amount of 0.5 to 20 wt%. In particular, the clay-like composition contains 0.5 to 20 wt% of the castor oil, 5 to 50 wt% of the polybutene resin having a molecular weight of 500 to 3000, and a kinematic viscosity (100 ° C.) of 2 to 5700 cst, and a molecular weight of 10,000. The polyisobutylene resin having a viscosity of ˜600,000 and a viscosity (200 ° C.) of 5,000 to 100,000 cst may be contained in an amount of 5 to 50 wt%. Such a clay-like composition is also described in Patent Document 1 as a clay-like cleaner. Therefore, the sheet-like or matte-like cleaner having this configuration can be easily obtained by dipping the base material in a clay-type cleaner proposed in Patent Document 1 in a solvent and then evaporating and removing the solvent. Is possible.

  In the present invention, as the filler, inorganic powders such as calcium carbonate, talc, clay, kaolin, silica, aluminum hydroxide, aluminum oxide, bentonite, diatomaceous earth, titanium oxide, glass, polyethylene resin, polypropylene resin, nylon, It can be selected from organic powders such as urea resin, phenol resin, and urethane resin, fibrous materials, or mixtures thereof.

  Moreover, it is also possible to select a resin fiber non-woven fabric made of vinyl, eval or PET, or a sponge made of silicon as the base material.

The filler preferably contains 30 to 90 wt% of an average particle size of 0.1 to 20 μm and an oil absorption of 15 to 55 cc / 100 g.
The base material may be a resin fiber non-woven fabric made of vinyl, eval or PET. Further, the base material may be a sponge made of silicon.

  As described above, the sheet-like or mat-like cleaner according to the present invention physically removes iron powder dirt, water, sap, etc. adhering to or sticking to a surface to be treated such as a coating film by using a clay-like composition. It is possible to finish the entire surface to be processed well, including parts with complicated shapes such as wheels and bumpers, even though the work and labor required for work can be reduced. In addition, there is an effect that it is excellent in handleability. In addition, there is the convenience that it can be used by being mounted on a polishing machine or the like.

  FIG. 1 is a schematic perspective view of a sheet-like or mat-like cleaner according to an embodiment of the present invention, and FIG. 2 is an enlarged partial sectional view thereof.

  The cleaner A illustrated in FIG. 1 or 2 is formed by holding a clay-like composition 20 that is plastically deformed on a flexible base material 10 having an internal space communicating with the outside. A flexible fiber material such as a nonwoven fabric or cloth is used for the substrate 10. Further, a soft sponge material such as a soft resin foam having open cells may be used. Whether the composition 20 is a single type of resin or a mixture of different resins, the composition 20 is a mixture containing solids and oil components mixed in these resins for an increase or for other purposes. May be. Furthermore, it may be an inorganic clay existing in the natural strata. Even if the composition 20 held on the base material 10 is held only on the outer surface of the base material 10, in addition to being held on the outer surface of the base material 10, It may be impregnated.

  Such a cleaner A has the property that the base material 10 has flexibility and the composition is plastically deformed, and thus bends freely and reasonably. Due to this property, when the cleaner A is overlaid on a surface to be processed (not shown) such as a coating film of an automobile, the cleaner A is well adapted to the shape of the surface to be processed and easily overlaps the surface to be processed.

  When this cleaner A is placed on a wet surface to be treated such as a coating film and the operator can move it manually with water as a lubricant, iron dust stains that adhere to or stick to the surface to be treated are covered. It is removed from the treated surface and taken into the clay-like composition 20 or the substrate 10. That is, iron powder stains or the like are taken into the composition 20 held on the surface of the substrate 10 or the composition 20 impregnated in the substrate 10. Therefore, the base material 10 is useful for wiping off stains on the surface to be treated, and the clay-like composition 20 held on the base material 10 is useful for removing persistent stains such as iron powder stains on the surface to be treated.

  In particular, this cleaner A has a property that the cleaner A is well adapted to the shape of the surface to be processed and overlaps with the surface to be processed without difficulty, so that complicated shapes such as automobile wheels and bumpers are formed. The cleaner is well adapted to the shape of the portion having the shape, and the entire surface to be processed can be finished well and easily including the portion having such a complicated shape.

  As shown in FIG. 1, the cleaner A is provided to the user, for example, having a square or rectangular shape. The size of the cleaner A is such that it can be covered with the palm of the user (operator). It is desirable that each length in the vertical and horizontal directions is 8 to 20 cm. When the size of the cleaner A is about this level, the operator can easily place the hand on the cleaner A placed on the surface to be processed and move in any direction on the surface to be processed. Is obtained.

  The thickness of the base material 10 used in the cleaner A is desirably 1 to 20 mm in sheet form or mat form. If the thickness of the base material 10 is less than 1 mm, the amount of the clay-like composition 20 retained will be too small, and iron powder stains and the like may not be sufficiently removed. When the thickness of the substrate is thicker than 20 mm, the amount of the composition 20 used per construction area is excessive, and the composition 20 is likely to be wasted. If the base material 10 is in the form of a sheet or mat with a thickness of 1 to 20 mm, the entire composition 20 is efficiently used to take up iron powder stains and the like, and good usability is obtained. It is done. In particular, if the thickness of the base material 10 is relatively thick (for example, 10 mm or more) within the range of 1 to 20 mm, the base material 10 exhibits a cushioning action. When moved on the surface, the pressing force of the cleaner A is uniformly applied to the surface to be processed, which has the advantage of helping to finish the entire surface to be processed uniformly.

  As a method for holding the clay-like composition 20 on the base material 10, a dipping method can be suitably employed. The dipping method is a method based on a simple and simple process in which a substrate is dipped into a solution in which a composition is uniformly dissolved in a solvent and then the solvent is removed by evaporation. When the cleaner A is manufactured by the dipping method, the cleaner A can be manufactured easily and inexpensively.

  When using the dipping method for the production of cleaner A, when using clay (particle size of 0.1 to 30 μm is desirable) existing in the natural formation in the clay-like composition, put the clay in a solvent such as water. It is possible to go through a step of sufficiently stirring and dipping the base material into the thick dissolved liquid clay so obtained to impregnate the clay, and then evaporating and removing the water. Further, when a single type of resin or a mixture of different resins is contained in the clay-like composition, or when these resins contain a solid content or an oil content, the base material 10 is contained in the composition dissolved in a solvent. Can be impregnated with the clay-like composition, and then the solvent is evaporated and removed. Alternatively, by making a high viscosity composition in advance, dipping the substrate into a solution in which it is dissolved in a solvent to impregnate the clay-like composition, and then evaporating and removing the solvent Can be manufactured easily and inexpensively.

  For the clay-like composition, a polybutene resin that is widely used as a non-drying putty or the like for a building sealing material can be suitably used. Polybutene resin is non-drying and its plasticity and viscosity are very similar to those of clay in natural formations.

  In addition to the polybutene resin, the clay-like composition includes a polyisobutylene resin, and further includes one or more fillers selected from inorganic powders, organic powders, and fibrous materials. It may be a thing. Although polybutene resin and polyisobutylene resin have large adhesiveness and frictional resistance against contaminants and foreign matter (iron powder, etc.) on the surface to be treated, they have a drawback of relatively small dynamic strength. The filler material helps to compensate for this drawback. In other words, polybutene resins and polyisobutylene resins have properties that are close to liquid even though they are clay-like, so additional clay is added to obtain a clay state with a large viscosity, and the clay-like or semi-solid state is maintained. To increase the dynamic strength. Thus, if the dynamic strength of a clay-like composition is raised, the removal capability of the iron powder stain | pollution | contamination adhering to the to-be-processed surface or sticking will improve. Furthermore, if the surface of the filler is hydrophobized, it can be easily mixed with polybutene resin or polyisobutylene resin. Further, there is an advantage that the slipperiness when processing the surface to be processed is improved, and the workability is improved accordingly.

  Furthermore, in addition to the polybutene resin, polyisobutylene resin and filler, the clay-like composition may further contain castor oil. If castor oil is added, the adhesive strength of the polybutene resin or polyisobutylene resin is alleviated. Therefore, without leaving the foreign matter removing effect, the operator's hand remains sticky or the composition is less likely to remain on the surface to be processed. Castor oil is a light yellow to yellow-brown viscous liquid obtained from castor seeds, and those which are standardized according to industrial, refined, Japanese pharmacopoeia and cosmetic raw material standards can be used.

  The component composition ratio when a polybutene resin, a polyisobutylene resin, a filler, and castor oil are included in the clay-like composition is exemplified below.

  The polybutene resin has a molecular weight of 500 to 3000, a dynamic viscosity (100 ° C.) of 2 to 5700 cst, 5 to 50 wt%, and the polyisobutylene resin has a molecular weight of 10,000 to 600,000 and a viscosity (200 ° C.) of 5000 to 100,000 cst. It is appropriate to use 5 to 50 wt% of the filler, 30 to 90 wt% of the filler having an average particle size of 0.1 to 20 μm, an oil absorption of 15 to 55 cc / 100 g, and 0.5 to 20 wt% of castor oil. This component composition ratio is equivalent to the component composition ratio of the clay-like cleaner proposed by the above-mentioned Patent Document 1.

  The filler has an average particle size of 0.1 to 20 μm, an oil absorption of 15 to 55 cc / 100 g, calcium carbonate, talc, clay, kaolin, silica, aluminum hydroxide, aluminum oxide, bentonite, diatomaceous earth, titanium oxide. Further, inorganic powders such as glass, organic powders such as polyethylene resin, polypropylene resin, nylon, urea resin, phenol resin, and urethane resin, fibrous materials, or mixtures thereof can be used.

  When the base material 10 is impregnated with the clay-like composition 20 by the dipping method, the composition content of the solution is preferably 20 to 90%. If the composition content is less than 20%, the base material cannot be impregnated with a sufficient amount of the composition. On the other hand, if it exceeds 90%, it is difficult to perform the step of dipping the base material into the solution. Become.

  Moreover, it is desirable that the weight of the viscous composition impregnated in the base material is equal to or more than the weight of the base material. When the composition impregnated with a weight less than the weight of the substrate is impregnated, the composition may be too small to obtain a sufficient treatment effect.

  In the case of using clay existing in the natural formation in the clay-like composition, it is desirable to use clay having a particle size of 0.1 to 30 μm. Clay having a particle size smaller than 0.1 μm is difficult to obtain and leads to high costs. When the particle diameter exceeds 30 μm, the surface to be treated such as a coating film is likely to be damaged.

  Further, when the base material 10 is impregnated with the clay-like composition by the dipping method, it is desirable that the layer thickness of the composition attached to the surface of the base material 10 is at least 1 mm. This is because if the layer thickness of the composition on the surface of the substrate 10 is too thin, the frequency of rubbing the substrate directly against the surface to be treated increases, which may reduce the action of taking up iron powder stains by the composition. .

  The sheet-like or mat-like cleaner A illustrated in FIG. 1 is desirably provided to the user by being enclosed in a packaging material (a bag made of a resin sheet). When provided in this form, it is required that the solvent contained in the cleaner A be sufficiently volatilized and removed. This is because if the solvent remains in the cleaner A, the solvent may attack and deteriorate the packaging material if the solvent is an organic solvent, and if the solvent is water, This is due to the need to add preservatives to prevent water decay. It is also possible to provide the cleaner A by wrapping it in paraffin paper and putting it in a packaging material.

  Next, examples and comparative examples will be described. In Examples and Comparative Examples, a viscous composition having the same components as those of the clay-like cleaner proposed by the above-mentioned Patent Document 1 is placed in a solvent such as water and sufficiently stirred, and thus It is obtained through a process of dipping the base material into the resulting thick dissolved liquid clay to impregnate the clay, and then evaporating and removing the water. In addition, the component of the clay-like cleaner proposed by Patent Document 1 is polybutene resin, polyisobutylene resin, filler, and castor oil as an oil component.

  Table 1 shows examples and comparative examples that are held on each substrate together with the components of the substrate (type of material forming the substrate), shape (property), basis weight, thickness (thickness). The composition and content of the viscous composition are shown. Table 2 shows the performance evaluation of each of the sheet-like or mat-like cleaners for the examples and comparative examples in a four-step determination. Table 3 shows comparative products and their performance as comparative examples.

The symbols for the four-stage judgment of performance evaluation shown in Table 2 and Table 3 indicate the following matters.
◎: Excellent ○: Good △: Slightly good ×: Not possible Workability can be completed in a short time, whether or not it is easy to follow the construction surface when constructed on an automobile wheel with iron powder attached It was evaluated whether or not.
Detergency evaluated whether iron powder was able to be removed firmly, when constructing to the automobile wheel which iron powder adhered.
Durability evaluated the finishing condition and the presence or absence of the tearing of a base material when three automobile wheels to which iron powder was adhered were constructed.
The overall result A indicates that “the thickness of the substrate is thin and the amount of clay impregnation cannot be increased, and the durability is not due to the thin substrate”.
The overall result B shows that “when the thickness of the base material is increased, it becomes too hard depending on the material and the flexibility is lost. Also, when the amount of impregnation is increased, the base material is buried in clay”. .
The overall result C indicates that “the cleaner property is not exhibited because the clay content is low (or not)”.

  Tables 1 and 2 revealed the following matters.

In Comparative Examples 1 and 2, when the thickness of the base material was 1 mm or less, the workability evaluation was a result of “good”, and the comprehensive result was “not good” or “good”. In particular, since Comparative Example 1 was extremely thin with a base material thickness of 0.3 mm, it was not possible in terms of durability and cleanability, and the overall result was not possible.
In Comparative Example 3, the base material thickness is 1 mm or more. However, since the content of the clay-like composition is too small with respect to the basis weight of the base material, workability and cleanability are impossible, and the overall result is also impossible. Also in Comparative Example 4, although not as bad as Comparative Example 3, it was only slightly better in each item.
In Comparative Example 5, since the castor oil composition in the clay-like composition was not included, workability was poor and comprehensive evaluation was impossible.
In Comparative Example 6, the amount of the filler was 30 wt or less, and since the amount of the filler was too small, the workability was poor, and the overall evaluation was only “Yamara”.
In Comparative Example 7, the polybutene composition in the clay-like composition is 55%, which exceeds the proper composition range of 5 to 50 wt%. As a result, workability was poor and the same results as in Comparative Example 6 were obtained.
Comparative Example 8 had the same result as Comparative Example 6 because the polyisobutylene composition in the clay-like composition exceeded the proper composition range of 5 to 50 wt%.
Comparative Example 9 also had the same result as Comparative Example 6 because the castor oil composition in the clay-like composition exceeded the appropriate composition range of 0.5 to 20 wt%.
In Comparative Example 10, since the compositions of polybutene and polyisobutylene in the clay-like composition were both 3 wt% and less than the proper composition range of 5 to 50 wt%, the same results as in Comparative Example 6 were obtained. .
In Comparative Example 11, the base material is a sponge. Even in this case, since the content of the clay-like composition is too small, workability, durability, and washability are impossible, and the overall result is also impossible. In addition, according to Example 6, it turned out that a sponge needs to have tolerance with respect to what melt | dissolved the clay-like composition.

In Examples 1, 2, 3, 4, and 5, the base material is a nonwoven fabric made of a material such as vinylon, and the composition range and content of the clay-like composition are appropriate. As a result, workability, cleanability and durability were all excellent, and overall results were excellent.
In Example 6, although the base material was a sponge, the result was that the workability, cleanability and durability were excellent, and the overall result was also excellent. From this, it was found that a sponge could be selected as the base material.

Next, when the vinylon nonwoven fabric alone, the eval nonwoven fabric alone, and the PET nonwoven fabric alone, which are comparative products shown in Table 3, were used for construction, the cleaning result was inferior, and the overall result was not possible.
Moreover, although the construction result by the clay-like composition (clay-like cleaner) proposed by patent document 1 is excellent in cleaning property and durability, it becomes impossible in workability, and the comprehensive result becomes impossible.

1 is a schematic perspective view of a sheet-like or mat-like cleaner according to an embodiment of the present invention. It is an expanded sectional view of the cleaner of FIG.
