Description

Detailed Description of the Invention A. Purpose of the Invention Industrial Application Field The present invention relates to a composition for cleaning vehicles using a high-pressure spray machine, and is particularly effective in removing water stains. Conventional technology In recent years, paid car washes using so-called brushing-type gate-type car wash machines have become rapidly popular at gas stations, and it has become possible to wax the car at the same time as washing the car. Technological innovations are being made.

However, this gate-type car wash machine has a brake that rotates at high speed.
For example, fender mirrors, wipers, etc.
This is a major drawback as it can damage protrusions on the vehicle such as antennas, side poles, and carriers. Another problem is that it is difficult for the brush to touch the recesses of the vehicle or the rear portions of the protrusions, making it impossible to achieve complete cleaning. Therefore, it is currently being considered that a vehicle can be washed by spraying a cleaning agent with a high-pressure spray V-machine without using this brush.

Problems to be Solved by the Invention When cleaning a vehicle using a high-pressure spray machine, water, hot water, surfactant deicing solution, aqueous solution of alkaline chemicals, etc. have been considered as cleaning agents. In this case, so-called water scale stains cannot be removed. In particular, water alone does not remove water stains at all, even hot water does not improve its effectiveness and costs more fuel, and even an aqueous solution containing a surfactant leaves a large amount of water stains, and a strong chemical containing 7μ potassium If this is used, problems such as swelling and discoloration of the paint may occur.

In this way, conventional cleaning agents used for high-pressure sub-V one-way vehicle cleaning cannot completely remove water stains from vehicles.
In any case, manual scraping 9 is required, which requires a great deal of effort and time.

It goes without saying that if this water stain is left unremoved, it will gradually accumulate, reducing the gloss and greatly detracting from the beauty of the car.

The present invention aims to solve this problem,
The objective is to develop a composition that can completely remove water stains as a cleaning agent used when washing vehicles with a high-pressure spray machine.

Structure and operation of the invention The structure of the present invention is a cleaning agent for washing a vehicle using a high-pressure spray palm with a discharge pressure of 30 kg/d or more, and which contains particles in water or an aqueous surfactant solution. Diameter is 0.
High-pressure spray vehicle cleaning set F11. is characterized by containing an abrasive having a Mohs hardness of 1 to 5μ and 6 or less. Means for Solving the Problem The present inventors have developed a method of blending a material with an abrasive effect into a conventional cleaning agent mainly consisting of water or an aqueous solution containing a surfactant. Based on this research, we have found that a blend of abrasives that satisfies specific conditions is extremely effective in removing water scale stains using a single high-pressure spray method. The polishing agent is blended with water or an aqueous surfactant solution, and the polishing agent therein satisfies the following specific conditions.

The abrasive compounded in the composition of the present invention has a particle size of 0.1
It is required to meet two conditions: ~5μ and its Mohs hardness is 6 or less, and even if the particle size is within this range, if the Mohs hardness exceeds 6, it is inappropriate, and similarly Even if the Mohs hardness is 6 or less, the particle size is 0.1~
If it is outside the range of 5μ, the polishing agent is inappropriate.

If the particle size of this abrasive is within the range and a hard abrasive with a Mohs hardness exceeding 6 is used, the hardness will be too large and cause countless scratches on the painted surface of the vehicle, significantly reducing the gloss of the painted surface. This accelerates the deterioration of the paint, causing loss of luster, and scraping off the edges of the vehicle, causing significant damage to the vehicle and its painted surface.

In addition, if the Mohs hardness of this abrasive is within the range and the particle size is larger than 5μ, it is highly effective in removing water scale stains, but as with the high hardness mentioned above, it will damage the painted surface and reduce gloss and luster. This will accelerate the deterioration of the paint.

On the other hand, the Mohs hardness of this abrasive is within the range and the particle size is 0.1.
If the particle size is less than μ, the effect of removing water scale stains will be almost nil, as in the case of the above-mentioned soft hardness.

It is needless to say that an abrasive whose hardness and particle size both exceed the upper limits cannot be used because of the significant deterioration of the painted surface.Abrasives that satisfy the above two specific conditions, that is, can be used in the present invention. Possible abrasives include diatomaceous earth, talc,
Examples include zeolite, μsium carbonate, bentonite, kaolin, and dolomite, which can be used very suitably.

The content of the above-mentioned abrasive in the composition of the present invention (undiluted solution C) is preferably in the range of 1 to 30% based on the total composition, and even if 30% or more of the abrasive is contained, the stain removal effect will not change, so it is economical. On the other hand, if the content is less than 1 inch, the water stain removal effect will be greatly reduced.

Note that this cleaning agent has a undiluted composition that is applied to a high-pressure spray machine, and when it is actually discharged from a nozzle, a large amount of auxiliary water is mixed in to obtain high pressure. In other words,
The high-pressure sub-V-machine has a vibrator that sucks up the cleaning agent solution and a pipe that sends a large amount of discharge water to obtain high pressure.
Normally, the cleaning agent is sucked up by the suction force that jets out several tens of times the amount of water as the undiluted cleaning agent solution, and is subjected to high-pressure submersion.

Although the object of the present invention can be achieved by simply blending the abrasive with only water, better results can be obtained by blending the abrasive with an aqueous surfactant solution.

The surfactant is a normal cationic surfactant.

Any of anionic, nonionic, and amphoteric surfactants can be used.The combination of this surfactant improves the stability of the cleaning agent and also eliminates abrasives remaining on the painted surface. By washing with water, you can also obtain the effect of helping the water to be easily washed away from the entire vehicle.

The blending ratio of this surfactant to the cleaning composition is 1 to 1.
10th place is the best one.

The composition of the present invention has the above-mentioned composition.

It is a water-dispersed liquid cleaning agent, and it goes without saying that other additives may be mixed in as needed.

For example, when an organic solvent is added as another additive, the cleaning agent becomes an emulsion and becomes stable, and at the same time, the solvent causes water stains to swell, improving the cleaning effect. However, this polishing solvent has the problem of fire and pollution, and it is necessary to take precautions to prevent fire accidents and to perform post-treatment to prevent it from becoming a source of water pollution.

To explain the method of using the composition of the present invention, the cleaning agent of the present invention is put into a cleaning agent container of a high-pressure suction V-machine, and
Water is ejected from the nozzle at a rate of 0 to 8 nl, and the cleaning agent is sipped together with the water at a rate of 100 to 5 (10 ce per minute) and sprayed onto the vehicle. It is necessary that the discharge pressure is at least 80 Kg/cj or more, and if it is less than Rn Kg/d, water scale stains will not be removed. (IKg/i
This allows oil stains, flakes, and water stains on the painted surface to be thoroughly cleaned without damaging the painted surface.

In addition, if the pressure is too high, for example 180Kg/
If the discharge pressure exceeds i, the car body may become depressed, so care must be taken.

This high-pressure spray cleaning method according to the present invention is effective not only for cleaning the body of the vehicle, but also for cleaning the bottom of the car, such as the shimmer.Normally, during vehicle inspections, the bottom of the car is cleaned incompletely, so oil stains and dust remain. However, if the bottom of the car body is cleaned using the method described above according to the present invention, complete cleaning can be achieved and favorable results can be obtained in terms of the adhesion of the rust-preventive paint. In the present invention, the distance between the discharge nozzle of the high-pressure spray and the painted surface of the vehicle is suitably between 30 and 1,001 degrees, and most preferably about 50C111. Moreover, it goes without saying that a simple wash with water is required after washing with the high-pressure bath V-.

Example Passenger car 9 of the same model C8 produced with a white painted surface
A test vehicle was prepared by applying normal waxing to the vehicle and leaving it outdoors in the same location for one month, with a considerable amount of water stains attached.

These nine test cars (Mal to Magnetic 9) were cleaned using a high-pressure spray machine in the following steps: (1) washing with water ↓ (2) spraying a cleaning agent ↓ (3) washing with water. (Distance between the discharge nozzle and the painted surface: 14
In this step (2), the test was carried out at a discharge rate of 151/min and a detergent suction rate of 3 (10 cc/min), and the discharge pressure at that time is as shown in Table 1 below.

The cleaning agent used in this step (2) had the following various formulations (compounds are parts by weight): Cleaning agent A Diatomaceous earth C Mohs hardness 4.5-5.5, particle size 3-5μ )・

...73 Cleaning agent G...Commercial product C (nonionic) Cleaning agent H...Commercial product (anionic) Of the above cleaning agents, four of the above cleaning agents A, B, C, and D are according to the present invention. In cleaning agent E, the particle size of diatomaceous earth is outside the range, and in cleaning agent F, the Mohs hardness of alumina is out of the range. This is a comparative example.

The above experimental results are shown in Table 1, (margins below c) Table 1 (Continuation of Table 1) In the above table, the discharge pressure 1B (IKg/cj is a confirmatory experiment with only A and B. Although the stain removal 9 effect was good, there was a problem with workability, so it was not tested in other experimental examples.The glossiness was measured using a glossy needle.

In addition, in Table 1 above, visual evaluations a to d are based on the following evaluation criteria: a: Water scale stains have also been removed.

b...Water stains remain, but oil stains have been removed.

C...Oil stains have not come off.

d...The water stains have been removed, but there are scratches on the painted surface.

From Table 1, by using the cleaning agents A, B, C, and D, which are compositions of the present invention, and increasing the discharge pressure, not only oil stains but also water scale stains are thoroughly cleaned. In another experiment, the most preferable range of discharge pressure was 5.
0 to 1 nnKg/cj, and 3 (I Kg/ct
; Most of the water scale stains can be removed if it is above, and a
It was confirmed that the removal of water scale stains did not suddenly deteriorate at a discharge pressure of less than nKg/d.゛Also, as shown in Table 1 above, if an abrasive with too large a particle size or an abrasive with too high hardness is blended, the higher the discharge pressure, the lower the glossiness will occur, causing the opposite effect on the painted surface. It has been determined that it can cause considerable scratches, and commercially available cleaning agents have been shown to have no ability to remove water scale stains.

C. Effects of the Invention As explained in detail above, the present invention makes it possible to wash a vehicle with a high-pressure sub-V-machine without using a plan, and also to remove water scale stains that could only be removed by hand in the past. This is a vehicle cleaning composition, and by applying this composition to a high-pressure vacuum cleaner, it is possible to clean a vehicle to a very beautiful and shiny state. Since it is not used, there is no need to worry about damaging the vehicle's protrusions such as fender mirrors, wipers, antennas, etc. Also, the rear parts of these protrusions and the recesses of the vehicle can be cleaned thoroughly, and the bottom of the car's chassis etc. It has various excellent effects such as being very effective for cleaning.
