Description

  The present invention relates to a car wash method for washing a vehicle to be cleaned and a car wash machine, and more particularly, to a coating on the surface of a vehicle to be cleaned using a gate type car wash machine.

  Conventionally, the coating of the surface of a vehicle to be cleaned using a portal-type car wash machine is performed by spray coating or brushing attached to a car wash machine with a coating agent obtained by emulsifying and dispersing a silicon compound such as amino-modified polysiloxane with a surfactant. It is done by rubbing. As an example, Patent Document 1 discloses that an amino-modified polysiloxane is emulsified with a nonionic surfactant and a coating agent containing a specific cationic surfactant is automatically applied.

Conventionally, scratches on the surface of a vehicle to be cleaned have been corrected by manually applying a composition in which a reactive organosiloxane and a catalyst are dissolved or dispersed in a solvent, or puffed with an abrasive. And it is corrected by polishing and repairing the surface. As an example, Patent Document 2 discloses a small wound repairing and polishing agent comprising a moisture curable organopolysiloxane, a film formation regulator, a volatile dimethylpolysiloxane, an organopolysiloxane, and dimethyl silicone oil (or alkyl-modified silicone). It is disclosed that it is used to correct flaws, and in Patent Document 3, flaws are corrected using a polishing coating agent containing a moisture curable silicone oligomer having a refractive index of 1.400 or more, a curing catalyst and a diluent.

The vehicle to be cleaned 12 is cleaned by the brushing device 16. Thereafter, drying by the drying device 18 is performed in the second return path in which the car wash machine main body 11 moves backward.

  By executing the water repellent coating course, as shown in FIG. 9A, when the water repellent coating agent is applied to the surface of the vehicle body of the vehicle 12 to be cleaned, the surface of the vehicle body is covered with the film α made of amino-modified silicon. . At this time, microscopically, the planarity can be improved, but light scattering occurs because there is no ability to fill the unevenness of the vehicle body surface (coating surface) over a wide area. Further, the coating α made of amino-modified silicon has a property of strengthening the adhesion between the mirror surface polymer agent and the hybrid polymer agent.

(Rinse) is sprayed, detergent is sprayed from the detergent nozzle 25, the vehicle 12 to be cleaned is cleaned by the brushing device 16, and then the second cleaning water nozzle 26 in the first return path in which the car wash machine body 11 moves backward. Then, washing water (rinse) is sprayed, and a water repellent coating agent is sprayed from the water repellent coating nozzle 22A.

  Subsequently, in the second forward path in which the car wash machine body 11 moves forward, cleaning water (rinse) is sprayed from the first cleaning water nozzle 21 to the vehicle 12 to be cleaned, and a mirror surface polymer agent is sprayed from the mirror surface polymer nozzle 22B. Thereafter, drying by the drying device 18 is performed in the second return path in which the car wash machine main body 11 moves backward.

  By executing this mirror surface polymer coat course, as shown in FIG. 9B, the vehicle body of the vehicle 12 to be cleaned on which the film α made of amino-modified silicon is formed (coated) by application of the water repellent coating agent. When a mirror surface polymer agent is applied to the surface, dimethyl silicon has a large colloidal state, so the coating β made of dimethyl silicon fills the unevenness of a wide area of the coating surface, smoothing the coating surface, eliminating light scattering, and glossing. A smooth feeling is drawn.

[2-round hybrid polymer coat course]
In the first forward path in which the car wash machine main body 11 moves forward, the wash water (rinse) is sprayed from the first wash water nozzle 21 and the second wash water nozzle 26 to the vehicle 12 to be washed, and the tilt type top HP hybrid polymer nozzle 23. The side HP hybrid polymer nozzles 24 </ b> A and 24 </ b> B are sprayed with high-pressure washing water (rinse), the detergent nozzle 25 is sprayed with detergent, and the vehicle 12 to be cleaned is cleaned by the brushing device 16. Thereafter, in the first return path in which the car wash machine body 11 moves backward, the wash water (rinse) is sprayed from the second wash water nozzle 26 to the vehicle to be washed 12, and the water repellent coating agent is sprayed from the water repellent coat nozzle 22A. The

  Subsequently, in the second forward path in which the car wash machine body 11 moves forward, the tilt type top HP hybrid polymer nozzle 23 is caused by the top swinging device 75 to increase or decrease the vehicle height of the vehicle 12 to be cleaned detected by the vehicle shape detection sensor 42. The swinging speed is increased / decreased (the swinging speed is increased when the vehicle height is high), and the tilting side HP hybrid polymer nozzle 24A is As the vehicle height of the to-be-cleaned vehicle 12 detected by the detection sensor 42 is increased or decreased, the swing speed is increased or decreased (the swing speed is increased when the vehicle height is high) and the vehicle is swung in the vertical direction. At the same time, the hybrid polymer agent is sprayed from the tilt type top HP hybrid polymer nozzle 23 and the side HP hybrid polymer nozzles 24A and 24B on the surface of the vehicle 12 to which the water repellent coating agent is applied. 2 Wash water (rinse) is sprayed from the wash water nozzle 26. Thereafter, drying by the drying device 18 is performed in the second return path in which the car wash machine main body 11 moves backward.

  When the vehicle height of the vehicle 12 to be cleaned is increased by executing this two-way hybrid polymer coat course, the swing speed of the tilt type top HP hybrid polymer nozzle 23 and the tilt type side HP hybrid polymer nozzle 24A is increased.

  Now, as shown in FIG. 10A, a state in which the hybrid polymer agent is applied to the upper surface of the vehicle 12 to be cleaned by the tilt type top HP hybrid polymer nozzle 23 will be described.

  For example, in the case where the tilt type top HP hybrid polymer nozzle 23 is swung in accordance with the vehicle to be cleaned 12 having a low vehicle height, when the vehicle height increases, the injection region that is the spread on the surface of the vehicle 12 to be cleaned, that is, the injection The width becomes narrower. FIG. 10B shows the injection width A when the vehicle height is low, and FIG. 10C shows the injection width B when the vehicle height is high. That is, as shown in FIG. 10C, when the vehicle height is high, an uninjected region D is generated. However, when the swing speed of the tilt type top HP hybrid polymer nozzle 23 is increased, the hybrid polymer agent is applied twice on the upper surface of the vehicle 12 to be cleaned, as shown in FIG. The non-injection area D generated between the injection areas can be eliminated. Of course, the set rocking speed and the vehicle height are in a relationship such that there is no unwashed area (uninjected region D).

  Further, in the case of the tilt type side HP hybrid polymer nozzle 24A, as the vehicle height increases, the range of the side surface of the vehicle 12 to be cleaned that must be sprayed from the nozzle 24A widens upward. There is a possibility that an uninjected area may occur (of course, the vertical swing angle of the nozzle 24A is set in consideration of the height of the side surface of the vehicle 12 to be cleaned, but there is a possibility that an uninjected area may be formed at the upper part of the side surface. is there). When the swinging speed of the tilt type side HP hybrid polymer nozzle 24A is increased, the range in which the injected hybrid polymer agent spreads becomes wider in the vertical direction, and the upper uninjected region can be eliminated. The hybrid polymer agent can be applied to the side surface twice.

  Further, as shown in FIG. 9C, by executing this two-way hybrid polymer course, the vehicle body of the vehicle 12 to be cleaned in which the film α made of amino-modified silicon is formed (coated) by application of the water repellent coating agent. When the hybrid polymer agent is applied to the surface at a high pressure, a hybrid film γ composed of an amino-modified polysiloxane and a polymer fine particle substance is formed (detailed chemical action will be described later).

[3 round trip hybrid polymer coat course]
In the first forward path in which the car wash machine main body 11 moves forward, the wash water (rinse) is sprayed from the first wash water nozzle 21 and the second wash water nozzle 26 to the vehicle 12 to be washed, and the tilt type top HP hybrid polymer nozzle 23. The side HP hybrid polymer nozzles 24 </ b> A and 24 </ b> B are sprayed with high-pressure washing water (rinse), the detergent nozzle 25 is sprayed with detergent, and the vehicle 12 to be cleaned is cleaned by the brushing device 16. Thereafter, in the first return path in which the car wash machine main body 11 moves backward, the washing water (rinse) is sprayed from the first washing water nozzle 21 and the second washing water nozzle 26 to the vehicle 12 to be washed, and the brushing device 16 performs washing. The vehicle 12 is cleaned.

  Subsequently, drying by the drying device 18 is performed in the second forward path in which the car wash machine body 11 moves forward. Thereafter, in the second return path in which the car wash machine body 11 moves backward, the wash water (rinse) is sprayed from the second wash water nozzle 26, and the water repellent coating agent is sprayed from the water repellent coat nozzle 22A.

  Subsequently, in the third forward path in which the car wash machine main body 11 moves forward, the tilt type top HP hybrid polymer nozzle 23 is caused by the increase or decrease in the vehicle height of the vehicle 12 to be cleaned detected by the vehicle shape detection sensor 42 by the top swing device 75. The swinging speed is increased or decreased (the swinging speed is increased when the vehicle height is high) and swings in the left-right direction Y. The tilt side HP hybrid polymer nozzle 24A is As the vehicle height of the to-be-cleaned vehicle 12 detected by the detection sensor 42 is increased or decreased, the swing speed is increased or decreased (the swing speed is increased when the vehicle height is high) and the vehicle is swung in the vertical direction. At the same time, the hybrid polymer is sprayed at high pressure from the tilt type top HP hybrid polymer nozzle 23 and the side HP hybrid polymer nozzles 24A and 24B onto the surface of the vehicle 12 to be cleaned to which the water repellent coating agent is applied. Wash water (rinse) is sprayed from the wash water nozzle 26. Thereafter, drying by the drying device 18 is performed in the third return path in which the car wash machine body 11 moves backward.

  By executing the three-way hybrid polymer coat course, the brushing is firmly executed twice, and when the vehicle height of the vehicle 12 to be cleaned becomes high, as in the case of the two-way hybrid polymer coat course, the tilt type top HP hybrid polymer nozzle is used. 23 and the tilt-type side HP hybrid polymer nozzle 24A are swung faster, and the hybrid polymer agent is applied to the upper surface of the vehicle 12 to be cleaned twice at a high pressure. Region D is lost.

  Further, as shown in FIG. 9C, by executing this three-way hybrid polymer course, the vehicle body of the vehicle 12 to be cleaned on which the film α made of amino-modified silicon is formed (coated) by application of the water repellent coating agent. When the hybrid polymer agent is applied to the surface at a high pressure, a hybrid film γ composed of an amino-modified polysiloxane and a polymer fine particle substance is formed (detailed chemical action will be described later).

  Control in the selected car wash course is executed by the control device 48. That is, as shown in FIG. 3, the control device 48 receives from the first operation panel 46 data necessary for car washing, for example, an operation signal such as a setting signal of a selected normal car washing course, starting and stopping. A special car wash course setting signal selected from the second operation panel 47 is input, and further, a detection signal from the vehicle shape detection sensor 42 and a detection signal from the traveling encoder 44 are input. The brushing device 16 (brushes 31, 32, 33) and the spray device 17 (first electromagnetic valves 59 of the nozzles 21, 26, nozzles 22 </ b> A, 22 </ b> B, 25) according to the signals from 46 and 47 and the detection signals of the sensors. , 27 second electromagnetic valve 60 and third electromagnetic valve 64B, nozzles 23, 24A, 24B fourth electromagnetic valve 69 and fifth electromagnetic valve 73B), drying device 18 (nozzle 5, 36, blower devices 38, 40), swing devices 75, 76 (swing motors 86, 96), travel drive device 43, submersible pump 53 (first inverter 55), high pressure pump 65 (second inverter 66). To control the overall operation of the car wash machine main body 11 and execute a car wash operation based on the selected car wash course.

Hereinafter, the action and effect of the hybrid polymer agent injected on the surface of the vehicle 12 to be cleaned while being swung at a high pressure will be described.
As described above, the hybrid polymer agent comprises an amino-modified polysiloxane (I) excellent in adsorptivity and water repellency, a polymer fine particle substance (II) excellent in gloss and slipperiness, and the above (I) (II). A hybrid polymer (composition) composed of at least one of a nonionic surfactant or a cationic surfactant (III) to be emulsified and dispersed and diluted with water is jetted at high pressure while being swung. Application (high pressure spray application) to the vehicle 12 to be cleaned.

  The surface of the paint is not smooth when viewed microscopically, and a large number of irregularities are present, and the damaged surface is more uneven. Due to the difference in the surface condition, the adhesion state of the correction agent component also varies greatly. The coating agent component easily adheres to the hydrophobic portion of the surface of the vehicle 12 to be cleaned, and a thick film is formed. On the other hand, in the hydrophilic portion, since a water film remains, it is difficult to adhere and a thin portion of the film is generated. Appears as uneven luster.

  When this hybrid polymer agent (composition) is applied at a conventional normal pressure (for example, 0.3 Mpa), the film component has low adhesion and forms a film that covers and hides small scratches on the surface of the vehicle 12 to be cleaned. Can not. Further, in order to obtain glossiness, slipperiness and surface protection, it is indispensable to mix the polymer fine particle substance. However, since the film viscosity is increased and the leveling property is lowered, the surface of the vehicle 12 to be cleaned is uniform. A film cannot be formed. However, in high-pressure (for example, 2.6 Mpa) spray application, a thick hybrid film γ that can fill and hide small scratches can be adhered without application unevenness.

This principle is explained as follows.
The amino-modified polysiloxane of the hybrid polymer component has a siloxane bond (Si-O) with a very low bond angle deformation energy in the molecule, so that the molecule is easily deformed, and the methyl group in the molecule is oriented to the air surface. Therefore, the film component is pressed by the physical force of the high-pressure spray, and contact with water and air is repeated, causing moisture and carbon dioxide CO ₂ to react, and the methyl group in the molecule to the air surface. By moving to orient, the polymer particulate material fills small scratches (invisible irregularities) on the surface of the vehicle 12 to be cleaned, and the level is homogenized and made of a hardened, thick amino-modified polysiloxane and polymer particulate material. The hybrid film γ adheres without application unevenness. Therefore, water repellency, glossiness, and slipperiness are imparted, aesthetics are improved, and the surface is protected. This hybrid film γ has a greater effect of filling small scratches (invisible irregularities) than the film β made of dimethyl silicon as a mirror surface polymer agent, and is excellent in durability.
"Amino-modified polysiloxane (I)"
Amino-modified polysiloxane (I) (hereinafter abbreviated as Component I) having excellent adsorptivity and water-repellency is generally an amino equivalent of 1000 to 4000 g / mol and a kinematic viscosity of 100 to 3000 mm, which are generally used for coating agents for vehicle surfaces. ² / s can be used, and those of 1500 to 3000 g / mol and 300 to 2000 mm ² / s are particularly preferable.

If the amino equivalent is too high, the adsorptivity decreases and the adhesion to the vehicle body surface of the vehicle 12 to be cleaned decreases, and if it is too low, the reactivity increases and problems such as yellowing of components occur.
If the kinematic viscosity is too high, spots and unevenness are likely to occur on the surface of the vehicle body. If the kinematic viscosity is too low, the water repellency is lowered. In addition, one or two or more components may be mixed and used from the above amino equivalent and kinematic viscosity ranges.

This component (I) is adsorbed on the surface of the vehicle 12 to be cleaned and exhibits water repellency, and is crosslinked by moisture in the air and CO _{2 to be} converted into a solid, thereby acting as a binder for the polymer fine particle substance.
`` Polymer particulate material (II) ''
Polymer fine particle material (II) (hereinafter abbreviated as component II) with excellent gloss and slipperiness is a plastic whose particle diameter is 1 μm or less and forms solid particles at room temperature and is transparent. A hard substance having excellent slipperiness is preferable. For example, polyolefin resins such as polyethylene and polypropylene, acrylic resins such as polyacrylic acid, polyacrylic acid ester and polyacrylate, polytetrafluoroethylene, poly-capped trifluoroethylene, ethylene / tetrafluoroethylene copolymer, etc. Fluorine resin, silicone resin such as methylphenylpolysiloxane, urethane resin such as polyurethane, styrene resin such as polystyrene, and copolymer resin obtained by bonding these.

Component (II), together with component (I), fills small scratches on the surface of the vehicle and bleeds on the surface of the coating, thereby exhibiting high gloss, slipperiness and surface protection effects.
"Nonionic surfactants and cationic surfactants (III)"
At least one of the nonionic surfactant and the cationic surfactant (III) that emulsifies and disperses the components (I) and (II) is the adsorptivity of the component (I) to the surface of the vehicle 12 to be cleaned. As long as it does not inhibit, it can be selected from general ones. For example, as the nonionic surfactant, polyoxyethylene alkyl ether, polyoxyalkylene alkyl ether, polyoxyethylene fatty acid ester, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester and the like can be used. Examples of cationic surfactants include quaternary ammonium salts, alkylamine salts, and ethylene oxide adducts thereof.

In addition, it is desirable to use ion-exchanged water from which salts have been removed so that the water used in the hybrid polymer composition does not affect other components in the composition.
In preparation of the hybrid polymer composition, low temperature stabilizers such as lower alcohols, glycol ethers and polyhydric alcohols, component stabilizers such as antioxidants and ultraviolet absorbers, and emulsion stabilizers such as water-soluble polymer substances. Further, auxiliary agents such as preservatives, rust preventives, colorants, and fragrances may be added.

[評価結果／評論]
実施例１から３のＢ工程では、効果の違いはあるがいずれも傷修復性、撥水性、光沢性、滑り性に於いて十分な性能を有していた。これらは、発明の効果を如実に現している。
また、Ａ工程では、いずれの組成物でも、小傷を埋め隠すほどの皮膜を形成することはできず、均質性に於いてもシミ、ムラが発生した。

[Evaluation Result / Critique]
In Step B of Examples 1 to 3, although there were differences in the effects, all of them had sufficient performance in terms of flaw repairability, water repellency, glossiness, and slipperiness. These clearly show the effects of the invention.
Moreover, in the process A, it was not possible to form a film enough to cover the small scratches with any composition, and spots and unevenness were generated even in the homogeneity.

  Further, in Comparative Examples 1 and 2, a uniform film that buryes a small flaw was not obtained in both steps A and B. In Comparative Example 1, the amino-modified polysiloxane has a low amino equivalent and strong water solubility, so that sufficient adhesion cannot be obtained, and since the kinematic viscosity is low, the homogeneity is good, but the film is also thin and does not exhibit slipperiness. As a result.

  Furthermore, in Comparative Example 2, the amino equivalent of the amino-modified siloxane and the kinematic viscosity are too high, so the performance of the coating component is high but the adhesion is poor, and it cannot be homogenized even by performing the high-pressure spray coating of the present invention. It was.

In Comparative Example 3, the particle diameter of the polymer fine particle substance was too large, and the film formed on the vehicle surface powdered, and the original film performance could not be exhibited.
From the above test results, in order to easily and quickly correct small scratches on the vehicle body surface of the vehicle 12 to be cleaned using the car wash machine body 11, the tilt type top HP hybrid polymer nozzle 23 and the side HP hybrid polymer nozzle 24A, It has been demonstrated that the combined use of high pressure spray application from 24B and the corrector composition is a prerequisite.

Invisible irregularities) can be corrected, water repellency, glossiness and slipperiness can be imparted, aesthetics can be improved, and a coating film with a protected surface can be formed. In particular, this is effective when the vehicle 12 to be cleaned is a pearl metallic vehicle in which small scratches on the surface are conspicuous or a vehicle having a dark paint color (dark vehicle).

Even if there is a difference in the vehicle type such as a one-box car having a high vehicle height, or there is a change in the vehicle height in one vehicle 12 to be cleaned, for example, a car in a bonnet part and a ceiling part (roof part) in a normal passenger car. Even if there is a difference in height, it is possible to prevent a region where the hybrid polymer agent is not applied on the surface of the vehicle 12 to be cleaned, regardless of the height of the vehicle, and evenly on the surface of the vehicle 12 to be cleaned. It can be applied hybrid polymer material to one.

  Further, according to the present embodiment, a “2 reciprocating hybrid polymer coat course” and a “3 reciprocating hybrid polymer coat course” are newly provided, and the car washing course for applying the hybrid polymer agent to the surface of the vehicle 12 to be cleaned is executed. As a result, not only cleaning of the vehicle 12 to be cleaned but also irregularities on the surface of the vehicle 12 to be cleaned can be corrected, and water repellency, glossiness and slipperiness can be imparted to the vehicle 12 to be cleaned, and the appearance can be improved.

In the present embodiment, the first operation panel 46 and the second operation panel 47 are provided separately. However, the functions may be integrated into one operation panel.
In the present embodiment, the vehicle height detection sensor 42 is provided as a vehicle height detector. However, the present invention is not limited to the vehicle shape detection sensor 42, and the vehicle height of the vehicle 12 to be cleaned is detected by an ultrasonic sensor or the like. It may be.

  In the present embodiment, the hybrid polymer agent is applied twice to the surface of the vehicle 12 to be cleaned. However, the present invention is not limited to two times, and the tilt type top HP hybrid polymer nozzle 23 and the tilt are further limited. By increasing the rocking speed of the formula side HP hybrid polymer nozzle 24A, coating can be performed more times.

  Further, in the present embodiment, the tilt type top HP hybrid polymer nozzle 23 is disposed at a constant height. For example, a vehicle to be cleaned can be cleaned by using a mechanism of a top nozzle 35 that can be moved up and down.
