Description

  The present invention relates to a polishing material used for cleaning and polishing hard surfaces such as glass, ceramics, porcelain, tiles, metals, plastics and floors, and a sponge scrubbing using the same. Further, the present invention relates to a polishing material used for cleaning and polishing such as cooking utensils and sponge scrubbing using the same.

  In addition to kitchens, toilets, washstands, and bathrooms are washed to keep them aesthetic and clean. As a cleaning method, an acid-to-alkaline cleaning agent and a cleaning article such as a brush, a scrubber, and a sponge are appropriately used. In particular, in cleaning toilets, acidic cleaning agents have been used to quickly remove yellowing in toilet bowls and toilet bowls and tile joints.

  In addition, neutral detergents that have a sanitizing effect and a deodorizing effect and that take into account work safety are also commonly used. In recent years, antifouling detergents having both a cleaning effect and an antifouling effect due to a silicone compound or a fluorine-based compound have been used.

  The antifouling cleaning agent has an effect of forming a coating film on the surface to be cleaned and making it difficult to be soiled at the same time as removing dirt. At this time, the use of the antifouling detergent at the time of each washing as in the case of the conventional detergent is economical and effective in effectively utilizing the antifouling effect that is the original feature of this detergent. It is not preferable.

  For this reason, when using an antifouling detergent, wash it with a sponge or the like using the antifouling detergent for the first time (the first day of washing), then rinse with running water, and the number after the next day (second time) Rinsing with a sponge soaked in water for a day, washing with water and only rinsing, no cleaning agent is used.

  However, in this cleaning method, when a sponge scrub with a high Mohs hardness and a high polishing power is used, a high cleaning effect can be obtained, but not only the surface to be cleaned is scratched. In addition, the coating film formed to exhibit the antifouling effect will be damaged and peeled off, and the antifouling effect cannot be sustained, and the gloss and good finish of the surface to be cleaned cannot be obtained. It will end up.

  On the other hand, when a soft sponge scrub with low Mohs hardness is used, the coating film formed to develop the antifouling effect will not be damaged and peeled off, but the desired cleaning effect cannot be obtained and cleaning is performed. Since dirt accumulates due to defects, a good finish of the surface to be cleaned cannot be obtained.

  In JP-A-7-236607 (see Patent Document 1), at least one abrasive particle selected from the group consisting of glass beads, silicon carbide, alumina, and natural shirasu is dispersed in a cellulose foam. An abrasive material and a kitchen sponge using the same are disclosed.

  Japanese Patent Application Laid-Open No. 2003-116762 (see Patent Document 2) discloses that a melamine sponge layer formed by foaming a melamine resin material and a urethane sponge layer formed by foaming a urethane material are thermally welded or adhesive. Discloses a sponge scrubbing joint temporarily bonded to releasably connect the split sponge scrubbing parts firmly stacked together.

  Further, in Utility Model Registration No. 3029809 (refer to Patent Document 3), in a sponge sponge with an abrasive material in which a sponge and a polishing surface are provided on one side thereof, the polishing surface is bonded to one side of the nonwoven fabric with an adhesive. A sponge scrubbing material with an abrasive for fixing scorch and rust such as pots, in which the abrasive particles are fixed and the other side of the nonwoven fabric is fixed to the sponge, is disclosed.

  JP-A-2000-265526 (refer to Patent Document 4) describes a ceramic toilet bowl that has been used and has a surface in which urine stains and silicate scale stains derived from trace components in tap water are fixed. In antifouling treatment, pre-cleaning treatment to remove scale stain and silicate scale stain is performed to expose the active new surface on the toilet surface, and then a water repellent that reacts with hydroxyl groups on the toilet surface and chemically bonds is applied. An antifouling treatment method for ceramic products is disclosed in which a hydroxyl group on the toilet bowl surface is shielded to form a water repellent film on the toilet bowl surface.

  JP 2000-345603 A (see Patent Document 5) discloses a step of applying an acid to a urine stone component on the surface of a sanitary ware such as a contaminated toilet and decomposing the surface, and then the surface thereof. Polishing with granular or powdery pearlite containing a surfactant and a thickening agent to remove contaminants and forming a fine etching rough surface for holding the coating agent on the surface along with the polishing, A solvent-type silicone-based coating agent is uniformly applied to the surface with an applicator having sponge elasticity or rubber elasticity to form a colorless and transparent cured film on the surface. A cleaning, polishing and coating method is disclosed.

  Further, the sponge scrubbing of the present invention is not only difficult to damage the surface of the object to be cleaned, but also in the cleaning polishing operation combined with the antifouling detergent, even if it is scrubbed with the sponge scrubbing of the present invention, the antifouling detergent Since dirt can be removed without damaging the formed antifouling coating film, the durability of the antifouling effect can be expressed synergistically.

  Therefore, by using the polishing material of the present invention and sponge scrubbing using the same, it is possible to obtain excellent cleaning performance, hardly damage the hard surface, and particularly in combination with an antifouling cleaning agent, The sustainability of the antifouling effect can be synergistically improved to maintain an economical and hygienic finish.

  In addition, the sponge scrubbing brush of the present invention is less likely to damage the hard surface and removes dirt. Therefore, it is also suitable for expensive crystal glass with food-derived dirt and over-coated tableware. It can also be used.

Hereinafter, embodiments of the present invention will be described in detail.
The abrasive material of the present invention is obtained by fixing an aggregate of silica and / or silicate abrasive particles as a polishing agent to a nonwoven fabric.

  As the abrasive used in the present invention, silica and / or silicate-based abrasive particles are aggregated. That is, an abrasive in which abrasive particles (primary particles) are aggregated to form aggregates (secondary particles) is used (see FIGS. 1 (i) and (ii)).

The average particle size of the abrasive particles (primary particles) is preferably 0.01 to 10 μm, more preferably 0.05 to 1 μm. The average particle size of the aggregate (secondary particles) is preferably 0.4 to 150 μm, more preferably 0.4 to 100 μm. The particle size D ₅₀ % value of the aggregate (secondary particles) is preferably 2 to 70 μm.

  The shape of the abrasive particles (primary particles) is preferably a needle shape, and the shape of the aggregates (secondary particles) is preferably a porous spherical shape.

As the silicate-based abrasive particles, for example, aluminosilicate abrasive particles represented by Na ₂ O—SiO ₂ —Al ₂ O ₃ are preferable.

  In addition, the Mohs hardness of the aggregate of abrasive particles used in the present invention is preferably set in a range of approximately 2 to 3.

  In the present invention, by using an aggregate of these abrasive particles, dirt can be removed without scratching the surface of the object to be cleaned. That is, as a result of various investigations on silica and silicate abrasives, which are soft particles, rather than hard particles such as alumina and silicon carbide, which are often used as abrasive particles, agglomerate the abrasive particles (primary particles). The present inventors have found that by breaking the aggregates during polishing, it is possible to remove dirt without scratching the surface of the object to be cleaned.

As the aggregate of abrasive particles used in the present invention, a commercially available product can be used. For example, an Al compound and a Si compound can be used in the presence of CO ₃ ²⁻ , SO ₄ ²⁻ , NO ₃ ⁻ , Cl ^{− and the} like. It can also be produced by a method of reacting in an alkaline solution. Examples of commercially available products include “Lunamos SP-PA” and “Lunamos SP-PB” manufactured by Kao Corporation.

  As a nonwoven fabric used for the abrasive material of the present invention, a nonwoven fabric using various fibers including natural fibers or synthetic fibers and mixtures thereof as a fibrous base material can be used. Examples of natural fibers include cotton, wool, jute and hemp. Synthetic fibers include polyester, polyamide, polypropylene, acrylic, rayon, cellulose acetate, polyvinylidene chloride-vinyl chloride copolymer, vinyl chloride-acrylonitrile copolymer. Etc.

  Among them, polyester, polyamide, polypropylene, acrylic, rayon, cellulose acetate, polyvinylidene chloride-vinyl chloride copolymer, vinyl chloride- from the viewpoints of fixing power of abrasives, reduction of detachment during cleaning and polishing, and improvement of polishing maintenance. It is preferable to use a nonwoven fabric containing at least one selected from acrylonitrile copolymers.

  The fiber thickness is preferably 3 to 100 denier, more preferably 5 to 30 denier.

  As a method for producing an abrasive material of the present invention, the above-mentioned aggregate of abrasive particles is mixed with a resin to form a slurry, which is fixed to a nonwoven fabric. Examples of the resin used at this time include an epoxy resin and a urethane resin. Further, the amount of the resin to be used can be 2 to 4 times the weight of the aggregate of abrasive particles.

  Examples of the method for fixing the slurry to the nonwoven fabric include blowing with an air gun, squeezing a roll after dipping, and the like.

The amount of the abrasive particles fixed to the nonwoven fabric is preferably 3 to 35 parts by mass with respect to 100 parts by mass of the nonwoven fabric.
If the fixed amount of abrasive particles is less than 3 parts by mass, the desired cleaning effect and polishing effect may be poor. Moreover, when it is made to stick exceeding 35 mass parts, abrasive | polishing material itself may become hard and the degranulation of the abrasive particle from a nonwoven fabric may increase.

Next, the sponge scrubber of the present invention will be described.
The sponge scrubber of the present invention is obtained by bonding the abrasive material and a sponge base material.

  Examples of the sponge substrate used in the present invention include those containing at least one selected from a phenol resin, an epoxy resin, a urethane resin, and a melamine resin. Among these, the use of a tough and flexible resin reduces the detachment of the abrasive from the abrasive material during work, and the workability without fatigue of the operator's hands due to moderate elasticity. Excellent and good cleaning and polishing will be obtained. For this reason, a phenol resin, an epoxy resin, and a urethane resin are preferably used, and a urethane resin is particularly preferable from the viewpoint of shape resilience.

  Further, as a method for adhering the abrasive material and the sponge base material, in addition to adhering with an adhesive, there may be mentioned thermal welding of the abrasive material and the sponge base material.

  The abrasive material may be adhered to only one side surface of the sponge base material, or may be adhered to two side surfaces, one side surface and the other side surface, and one or more side surfaces perpendicular to the one side surface. It may be adhered to.

  Further, the sponge base material may be provided with recesses in all or part of the two side surfaces facing each other in order to enhance workability (FIGS. 2 (i) to (iv), FIGS. 3 (iii) and (v). )reference).

  Further, a V-shaped or U-shaped groove, a conical or hemispherical concave portion or the like for effectively soaking the abrasive in the polishing material may be provided at one place or a plurality of places (FIG. 2 ( iii), see (iv)).

  The sponge scrubber of the present invention can be used for cleaning and polishing toilets, washstands, bathrooms, tableware, cooking utensils and the like.

  EXAMPLES The present invention will be described below with reference to examples and comparative examples, but the present invention is not limited to the following examples.

<Example 1: Production of abrasive material>
Porous aggregate of silicate-based abrasive particles (“Lunamos SP-PA” (manufactured by Kao Corporation)) (primary particle size 0.1 μm, secondary particle size 2 to 4 μm, Na ₂ O / SiO ₂ = 1.0 to 1.5, Al ₂ O ₃ / SiO ₂ = 2 to 3, particle size D ₅₀ % = 10 to 20 μm) 10 parts by mass and 30 parts by mass of epoxy resin were mixed, and the thickness was 15 denier. It was made to adhere to 60 mass parts of polyester nonwoven fabrics, and the abrasive material was obtained. The basis weight (g / m ² ) of the abrasive material (abrasive + resin + nonwoven fabric) at this time is 550 g / m ² , and the amount of the abrasive fixed to the nonwoven fabric is 100 parts by mass of the nonwoven fabric. It was 17 mass parts with respect to it. The thickness of the abrasive material after fixing was 7 mm.

<Example 2: Production of sponge sponge>
This abrasive material (length 75 mm x width 135 mm x thickness 7 mm) is bonded to a urethane resin (polyester urethane home) sponge base (length 75 mm x width 135 mm x thickness 40 mm) with recesses on both sides. Sponge scrubbing (length 75 mm × width 135 mm × height 43 mm) was obtained.

<Example 3: Cleaning test>
Using the above sponge scourer and antifouling cleaner (product name: “Crew Cleanval” / manufactured by Johnson Professional), urinals for public men's toilets, toilets (Western and Japanese) and washstands A cleaning test was conducted.

〔Test method〕
Rinse with a sponge scrubbing agent using the above antifouling detergent on the first day of washing, rinse with water, and for the next 13 days (second day), use a detergent that contains water without using any detergent. Rinse with a scrubber and rinse with water (1 cycle over 14 days). The state of dirt when this cleaning method was carried out for 1 month (2 cycles) was evaluated in comparison with the state of the first day of cleaning.

〔Evaluation results〕
After 1 cycle: No adhesion of dirt was observed, and the state was almost the same as the first day of cleaning.
After 2 cycles: No adhesion of dirt was observed, and the state was almost the same as the first day of cleaning.

<Comparative example: Cleaning test>
As a comparative example, according to the above cleaning test method, a case where a commercially available sponge sponge having a Mohs hardness of 6 was used was used as Comparative Example 1, and a case where a commercially available soft sponge brush having a Mohs hardness of 1 was used. It was set as Comparative Example 2.

〔Evaluation results〕
<Comparative Example 1>
After 1 cycle: No dirt was observed, but scratches on the surface to be cleaned were observed and the finish was not glossy.
After 2 cycles: No dirt was observed, but scratches on the surface to be cleaned were observed and the finish was not glossy.

<Comparative example 2>
After 1 cycle: Slight adhesion was observed (no scratches were found on the surface to be cleaned).
After 2 cycles: Slight dirt was observed (no scratches were found on the surface to be cleaned).

As described above, when using a sponge with a high Mohs hardness and a strong polishing force, a high cleaning effect can be obtained, but it not only damages the surface to be cleaned but also prevents it. The coating film formed in order to develop the fouling effect is also damaged and peeled off, so that the fouling prevention effect cannot be maintained, and the gloss and good finish of the surface to be cleaned cannot be obtained.
In addition, the persistent fall of the antifouling effect was seen from the 5th-7th day of washing | cleaning by water washing and a rinse.

In addition, when using a soft sponge scrub with low Mohs hardness, the coating film formed to express the antifouling effect was not damaged and peeled off, but the desired cleaning effect could not be obtained, Since dirt accumulates due to poor cleaning, the desired finish cannot be maintained.
In addition, adhesion of dirt was seen from the 7th to 10th days of washing with water and rinsing.

  On the other hand, it is understood that when the cleaning and polishing operation is performed by combining the sponge scrubber of the present invention and the antifouling detergent, the antifouling effect is maintained synergistically and a hygienic and good finish can be obtained.
