DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for treating a painted surface of a car body and a method for treating a painted surface of a car body.

[0002]

2. Description of the Related Art Wax treatment performed on a car body not only removes dirt attached to the car body or suppresses the attachment of dirt to the car body, but also imparts gloss and water repellency to the car body. However, the processing effect varies depending on the type of wax and the type of applicator used to apply the wax.

[0003] Cleaning of body painted surface (cleaning process)
And waxing (waxing treatment) are known as waxes in which abrasive particles are mixed in a wax liquid, and this kind of wax is usually made of urethane foam. It was applied to the painted surface of the car body using a sponge.

[0004]

However, since abrasive particles have a hydrophilic property compared to wax, petroleum resin, silicone resin, fluororesin, etc., if present in a wax solution, the abrasive properties of the wax coating will be reduced. As a result, the adhesion between the wax film and the painted surface is impaired, and as a result, the wax film is easily peeled off or disappeared from the painted surface in a short period of time. Further, after the wax is applied, the abrasive particles may remain in the wax film before wiping, and the wax film just formed by the abrasive particles may be scraped off during the wiping operation.

[0005] For these reasons, conventionally, the hydrophilicity of the wax film is increased and the wax film is easily lost, or the wax film is scraped off by wiping after the wax is applied. There is a problem that the performance exhibited by the wax coating such as the antifouling performance is significantly reduced. In other words, when the abrasive particles are present in the wax solution, there is a problem that the wax coating performance cannot be sufficiently obtained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has greatly improved the adhesion of a wax coating covering a vehicle body application surface to an application surface, and furthermore, the wax coating is removed by abrasive particles during a wiping operation. It is an object of the present invention to provide a wax treatment tool for a painted body of a vehicle, which is less likely to be damaged.

[0007] Another object of the present invention is to provide a wax treating tool for a painted surface of a vehicle body, which is unlikely to lower the wax performance exhibited by the wax itself.

It is another object of the present invention to provide a waxing tool for a painted surface of a vehicle body, which can perform a waxing operation in a short time.

Further, according to the present invention, it is possible to enhance the adhesion of the wax coating covering the vehicle body application surface to the application surface, and to perform the wax treatment on the vehicle body paint surface without scraping off the wax film by abrasive particles during the wiping operation. An object of the present invention is to provide a method for treating a painted surface of a vehicle body with wax.

[0010]

SUMMARY OF THE INVENTION According to the present invention, there is provided a wax treating tool for a painted surface of a vehicle body, the wax being applied to a painted surface of a vehicle body to form a coating covering the painted surface, and the wax being coated on the painted surface. An applicator for applying to the, the applicator is a sponge holding abrasive particles,
That is. The applicator holding the abrasive particles, even if it is made of a sponge holding the abrasive particles added before the foaming step, the sponge obtained by going through the foaming and curing step, the abrasive particles and the binder Impregnated with a mixture of the above, so that the sponge retains the abrasive particles. The waxes include those that do not contain abrasive particles and those that do.

In the present invention, the abrasive particles held by the sponge are added to the stock solution of the material when the sponge is manufactured. Therefore, even if wax is applied to the painted surface of the vehicle body using the sponge, It is unlikely that the abrasive particles fall from the sponge and mix into the wax coating. Also, when the foamed and cured sponge is impregnated with abrasive particles, the sponge is prevented from falling off by using a binder. Therefore, the abrasive particles held by the sponge do not mix with the wax coating covering the painted surface. As a result, even if the abrasive particles have hydrophilic properties, the abrasive particles do not impair the adhesion of the wax film to the painted surface, and the wax film is polished by the wiping operation after the wax application. No more shavings by particles. Therefore, the wax performance exhibited by the wax itself is directly exhibited by the wax coating. In addition, since the sponge for applying the wax holds abrasive particles, when the wax is applied to the painted surface of the vehicle body with this sponge, the abrasive particles contained in the sponge will remove the stain on the painted surface. Notably helpful.

From the above, by using the wax processing tool according to the present invention, cleaning and waxing of the painted surface can be performed in one operation, and the wax coating itself covering the painted surface can be obtained. , Durability, water repellency, and antifouling property (the property of suppressing dirt).

The material used for the sponge containing the abrasive particles is not particularly limited. Examples of the material forming the sponge include urethane foam, polyvinyl acetal sponge, melamine foam, foamed polyethylene, and the like. As abrasive particles, alumina, quartzite,
Examples thereof include cerium oxide, zirconium oxide, chromium oxide, silicon carbide, boron carbide, silicon nitride, boron nitride, diamond, calcium carbonate, calcium phosphate, zirconium silicate, zeolite, and diatomaceous earth.

When the average particle size of the abrasive particles is approximately 0.5 μm to 80 μm, preferably 1 μm to 60 μm in terms of the primary particle size, the polishing performance without damaging the painted surface of the vehicle body is exhibited. The amount of the abrasive particles is 10 to 600 wt% when the weight of the sponge is 100 wt%.
%, Preferably 40 to 500 wt%, good polishing performance is exhibited. The calculation method is as follows. Put the finished sponge in a thermostat at 100 ° C.
Leave for 2 days and measure the weight (dry weight of polishing sponge).
Thereafter, heat treatment is performed at 700 ° C. to remove organic substances, and the weight of the remaining inorganic substances is measured (weight of contained abrasive particles). It was calculated from the two weights thus measured. The finished sponge has an area of 20 to 300 cm when used.
² , preferably having a bottom surface of 50 to 250 cm ² and a columnar structure having a height of 0.3 to 10 cm, preferably 0.5 to 5.0 cm. This is not the case when attaching a handle, but the height from the bottom (surface used for coating) to the highest point of the handle is 1.0 to 25c.
m, preferably 1.5 to 10.0 cm. Other additives used when foaming and molding the sponge are not particularly limited.

The following test method was used to confirm whether a sponge satisfying the conditions listed above could withstand actual use.

The sponge was hand-rubbed 20 times in water, and the weight of the sponge fragments and abrasive particles falling off was set as a percentage of the sponge before being put in water, and compared and sorted. As a result, no problem occurred if the weight of the falling off portion was 3.0 wt% or less.

[0017] In the method for treating a painted surface of a car body according to the present invention, a wax or a compound containing abrasive particles is applied to a painted body surface of a car body using a sponge containing abrasive particles, and further contains no abrasive particles thereon. It is to apply wax. As in this method, when performing a work of applying a wax or a compound containing abrasive particles to a vehicle body painted surface using the sponge containing the abrasive particles, when a sponge containing no normal abrasive particles is used. In comparison with the above, dirt was removed quickly and neatly. There was no difference in the coating performance at that time, but if a wax containing no abrasive particles was further applied on top of this, a higher performance coating could be obtained by using a sponge containing abrasive particles first. Was done.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a wax treatment tool for a painted surface of a vehicle body according to the present invention will be described.

The wax processing tool comprises a wax for forming a coating applied to the painted surface of the vehicle body to cover the painted surface, and an applicator for applying the wax to the painted surface. As the wax, any of those containing no abrasive particles and those containing abrasive particles can be used, but when a wax containing no abrasive particles is used, a wax film containing no abrasive particles is formed. It becomes possible to do. A sponge holding abrasive particles is used for the applicator.

When this wax processing tool is used, it is possible to carry out wax treatment with an applicator holding the abrasive particles without putting the abrasive particles in the wax liquid. Hanging can be performed in one operation at the same time. Moreover, no abrasive particles are present in the wax liquid applied to the painted surface of the vehicle body or in the wax film after wiping, so that the wax liquid and the wax film are not hydrophilized by the abrasive particles, and the scraping during the wiping operation can be performed. Will not happen. As a result, in addition to the sufficient wax performance being obtained by the wax coating, the effect of adding the abrasive particles held by the sponge is obtained, and when applied with a sponge that does not hold the abrasive particles. A film having higher adhesion can be obtained.

Further, when a wax or a compound containing abrasive particles is subjected to a wax treatment on a painted surface of a vehicle body with a sponge containing abrasive particles, dirt can be removed more quickly and more cleanly than when a normal sponge is used. And, although there was no difference in the performance of the wax film when using the wax containing the abrasive, when a wax containing no abrasive particles was further applied thereon, it was more effective when using the sponge containing the abrasive particles. High performance coatings can be obtained. This point will be clarified by an experimental example described later.

By the way, the properties or characteristics of the wax film obtained by subjecting the painted surface of the vehicle body to a wax treatment include gloss, gloss, water repellency and water repellency exhibited by the formed wax film, and prevention of dirt. Stain and the like can be mentioned, and cleaner property by rubbing with a sponge when applying wax can be mentioned.

The performances of the wax film itself, such as glossiness, water repellency, and antifouling properties, are variously changed by combining wax, silicone oil, petroleum resin, fluororesin, silicone resin, etc. in various ratios. Can be done. Therefore, as the wax used in the present invention, those obtained by combining them in a desired composition can be used, and by doing so, the above-described properties such as glossiness and water repellency can be expressed in a complex manner. For example, “Soft 99 Hanneli”, which is commercially available from Soft 99 Corporation, contains abrasive particles and has excellent cleaner properties, and “Soft 99 Super Waterproof” does not contain abrasive particles but has water repellency. For glossiness, see "Soft 99
"Fluorine coat 7" and "Soft 99 fluorine coat"
"Annual waterproof solid" does not contain abrasive particles, but is excellent in water repellency and stain resistance.

In the wax processing tool of the present invention, a sponge obtained by holding abrasive particles on a polyvinyl acetal sponge or a polyurethane foam can be suitably used. Such a sponge containing abrasive particles needs to be added to the raw material solution before performing a foaming step performed for manufacturing the sponge, and by using such a sponge as an applicator, a wax coating is formed. Of the abrasive particles is prevented. In this regard,
There is no particular problem even if the sponge holds abrasive particles after the foaming step. However, if a large amount of abrasive particles fall off during use, the dropped abrasive particles are mixed into the wax film, and such a sponge containing abrasive particles is excluded from the applicator according to the present invention.

A sponge containing abrasive particles of polyvinyl acetal can be produced, for example, by the following procedure. Abrasive particles as abrasive particles and, if necessary, a pore-forming material such as starch are added to the aqueous polyvinyl alcohol solution, and aldehyde is further added thereto.
By heating for about 20 hours to acetalize the polyvinyl alcohol, a polyvinyl acetal sponge containing abrasive grains (PVA sponge containing abrasive particles) can be obtained. In addition, after adding a suitable surfactant to a polyvinyl alcohol aqueous solution and foaming beforehand, an abrasive and an aldehyde are added, and it can also be obtained by heating under an acid catalyst.

The polyurethane foam containing abrasive particles can be produced, for example, by the following procedure. Abrasive grains, water,
A polyurethane foam containing abrasive grains can be obtained by simultaneously adding a catalyst, a surfactant, a foaming aid, a foam stabilizer, and the like, mixing by vigorous stirring, and foam-curing. In addition, it can also be obtained by impregnating and adhering a mixed solution of abrasive grains and a binder to a polyurethane foam obtained in advance.

Next, an experimental example (test example) will be described.

Looking at Tables 1 to 10 together, it can be seen that sponge (a)
When (f) is used, the performance of the wax coating agent is sufficiently brought out, and the cleaner performance is imparted or enhanced. Furthermore, since cleaning is performed at the time of coating, the same film performance as that obtained when the undercoating treatment is performed is obtained.

The item "wax" none "" in each sponge was obtained by performing a polishing operation using only a sponge without using a wax coating agent. As a matter of course, no coating was obtained, and only those having abrasive particles exhibited cleaner performance. However, wax
The generation of scratches was slightly more noticeable than when the coating agent was used.

The sponges (g) and (h) are examples in which the size, the amount, the bottom area of the sponge, and the height of the abrasive particles (abrasive grains) are inappropriate. If the particle diameter is too small or the particle amount is too small as in the case of a sponge (g), the polishing effect could not be obtained. When the particle size is too large or the particle amount is too large as in the case of the sponge (h), the polishing effect is sufficiently obtained, but the coated surface is scratched. Further, if the area and height of the sponge were too large or too small, it became difficult to hold the sponge itself, resulting in poor working efficiency.

When the sponge (i) was used, the abrasive grains dropped off during use and each time after washing. Although it could not be described in the table, the cleaner performance was lost during repeated use. On the other hand, such a thing did not occur at all in sponge (e).

From the result of the sponge (j), the performance of the wax coating agent can be obtained with the urethane foam which is usually used, but it is necessary to use a sponge applicator as described in (a) to (f). It can be seen that the cleaner performance can be imparted and enhanced, and that an excellent and durable coating can be formed.

II. Base treatment and performance comparison To compare the difference in base treatment due to the difference in sponge,
The following method was used. (1) Using the sponge (a) and wax A, work was performed on the right half of the hood of a white painted car (1994 Nissan Primera). The work method is to wash with tap water, remove pebbles, sand, etc. on the painted surface, and wipe off the moisture with a dry towel. There, using a sponge (a),
Wax A was applied. After drying, it was wiped up with a clean towel. Next, wax D was applied with a sponge (j), dried and wiped off with a clean towel.

(2) Using the sponge (j) and the wax A, work was performed on the left half of the bonnet of the same white painted car (1994 Nissan Primera). The work method is to wash with tap water, remove pebbles, sand, etc. on the painted surface, and wipe off the moisture with a dry towel. Wax A was applied thereto with a sponge (j). After drying, it was wiped up with a clean towel. Next, wax D was applied with another new sponge (j), dried and wiped off with a clean towel to finish. Actually drive the car processed as described above with a target of 200 km per week,
Every one week, one month, two months, four months, and six months, the performance of water repellency and antifouling was checked. The confirmation method and reference numerals used in 0033 and 0034 were used as they were. The results are shown below.

[0053]

[Table 11]

[0054]

[Table 12] As is clear from the above two tables, it was found that the base treatment using the sponge containing the abrasive particles exhibited the performance for a longer time in both the water repellency and the antifouling property.

III. Work time superiority Work time was also examined and compared by the following methods. (1) White painted car (1993 type Nissan Bluebird) using sponge (b) and wax coating agent C
Work was performed on the table, and the time required for the work was measured.
The work method is to wash with tap water, remove pebbles and sand on the painted surface, and wipe off the moisture with a dry towel.
The wax C was applied thereto using a sponge (b). After drying, it was wiped up with a clean towel and finished.

(2) Sponge (j) and wax coating agent C, and “Soft 99, a new water-red annihilation liquid for white vehicles” commercially available from Soft-99 Corporation (hereinafter referred to as “water-annihilation”) ), A white-painted vehicle (1993 Nissan Bluebird) was subjected to a waxing operation in the same manner as described above, and the time required for the waxing operation was measured. The work method is to wash with tap water, remove pebbles and sand on the painted surface, and wipe off the moisture with a dry towel. Water sponge annihilation was applied thereto using a sponge (j). After drying, it was wiped up with a clean towel. Next, another new sponge (j) was used to apply wax C, and after drying, was finished by wiping with a clean towel.

Hereinafter, the time required for the work will be described. The cleaner properties, the water repellency after one week, and the antifouling properties were almost the same.

[0058]

[Table 13]

As is clear from Table 13, the work time of No. 1 is shortened by the small number of steps. Almost the same performance was obtained. From this, it was found that the work time of No. 1 was shorter than the work time of No. 2.

[0060]

As described above, when the wax processing tool according to the present invention is used, the adhesion of the wax coating covering the coating surface of the vehicle body to the coating surface is greatly improved. The possibility that the wax film is scraped off is reduced, and the wax performance exhibited by the wax itself is improved. Further, the waxing operation can be performed in a short time.

Further, according to the method for treating a painted surface of a vehicle body according to the present invention, a coating film having even better performance can be obtained.
