Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire wheel for a vehicle, and relates to a wheel rust remover and a method for producing the wheel rust remover.

[0002]

[Prior art]

Various kinds of oil and mud adhere to the surface of a vehicle tire wheel and fine iron dust sticks to the surface of the wheel. This is because the wheel is made of a relatively soft material and fine iron dust is generated and scattered when the disc brake mechanism arranged near the wheel is operated. When this fine iron dust adheres to the wheel, it oxidizes, causing rust to occur at the adhered portion. Therefore, various cleaners have been used so far in order to maintain the tire wheels of the vehicle.

[0004]

However, although the conventional cleaners are effective against various oils and muds other than rust, they are hardly effective against rust. That is,
Conventional cleaners did not consider the special oxidation conditions of tire wheels, so after removing oil or mud, rust must be removed with a separate agent after removing oil or mud. did not become. In this case, if a cleaner mixed with a compounding agent is used, rust removal can be performed, but at the same time, a problem that the wheel itself, which is a soft material, is damaged is newly caused.

There is also a method of removing the rust by acid-treating the rusting portion, but this method also causes a problem that the wheel itself, which is a soft material, is damaged at the same time as the rusting. Will end up. Therefore, although a cleaner mixed with a compounding agent is used or acid treatment is performed, it is conceivable to take time and work slowly so as not to damage the wheel itself, but this work is extremely complicated work by a skilled person. At the same time as being forced, there was a problem that sufficient rust removal could not be performed.

The present invention is proposed to solve these problems, and can remove rust and oil efficiently without removing the oil and mud adhering to the wheel without damaging the wheel itself. And a method for producing a wheel rust remover.

[0007]

In order to achieve the above object, the present invention provides: Carboxylic acid or glycolic acid is the first component, organic amine and amine hydroxide and aqueous ammonia are the second components, secondary alcohol ethoxylates and higher alcohols and ethoxylates and alcohol-based surfactants are the third components. As a component, polyhydric alcohol as a fourth component,
A wheel rust remover characterized by comprising ion-exchanged water as a fifth component.

[0008] 2. The weight of each component is about 25 parts for the first component, about 25 parts for the second component, about 2 parts for the third component, about 10 parts for the fourth component, and about the fifth part. The component was about 35 parts, and the wheel rust remover according to the above-mentioned item 1 was prepared.

3. After adding carboxylic acid or glycolic acid to ion-exchanged water, organic amine, amine hydroxide and ammonia water are added and the mixture is stirred and reacted for about 20 minutes to produce carboxylate or glycolate, and then secondary alcohol ethoxylate. And a higher alcohol, an ethoxylate, and an alcohol-based surfactant were added, and then a polyhydric alcohol was added and the mixture was stirred and mixed for about 30 minutes to provide a wheel rust remover manufacturing method.

[0010]

Embodiments of the present invention will be described below. The wheel rust remover according to the first embodiment of the present invention selects carboxylic acid (eg, thioglycolic acid) or glycolic acid as the first component, but this selects another material (eg, forms the wheel body). This is for preferentially reacting and dissolving rust, which is an iron oxide, with respect to (iron ingot). Therefore, it is possible to remove rust without damaging the wheel body. Further, carboxylic acid (for example, thioglycolic acid) becomes purple when it reacts with rust which is an iron oxide. Therefore, it is easy to confirm the effect of rust removal during work.

Next, an organic amine, an amine hydroxide and aqueous ammonia are selected as the second component, which is a human body by selecting carboxylic acid (eg thioglycolic acid) or glycolic acid as the first component. This is to eliminate the risk of damage to the wheel and to avoid the adverse effect of rust removal, which causes oxidation of the wheel due to residual adhesion of the first component. In other words, a base with strong acidity and alkalinity may cause strong irritation to the skin etc. by contact, and when applied to the target site for rust removal, rust will be generated on the coated surface after the passage of time. There is a risk of causing it. Therefore, the second component is added to the first component and mixed with stirring to cause a neutralization reaction.

Next, secondary alcohol ethoxylates and higher alcohols and ethoxylates and alcohol-based surfactants are selected as the third component. These are mainly dissolved in the aqueous solution by the action of the surfactants and have a surface tension. It is for reducing. By using the third component in this way, the permeability as a rust remover is improved,
Even pinhole-like fine rust stuck into the wheel can be reliably removed.

Similarly to the third component, the polyhydric alcohol selected as the fourth component also improves the permeability as a rust remover, and reliably removes the pinhole-like fine rust stuck in the wheel. It is to be able to. Further, the third component and the fourth component have strong cleaning properties for oil and the like, so that the treated surface can be efficiently cleaned together with rust removal by the first component and the second component. Also,
Ion-exchanged water is selected as the fifth component, which is for diluting the rust remover to an appropriate concentration.

Next, a method of manufacturing the wheel rust remover according to the second embodiment of the present invention will be described. First,
After adding carboxylic acid or glycolic acid to ion-exchanged water, add organic amine, amine hydroxide, and ammonium hydroxide to about 2
The reaction is carried out with stirring for 0 minutes to produce a carboxylate or glycolate. The reaction mechanism at this _{time, R-COOH + NH 4 OH} → R-COONH 4 + H 2 O
(R: alkyl group) Thus, the compound carboxylate can be obtained. After that, a secondary alcohol ethoxylate, a higher alcohol, an ethoxylate and an alcohol-based surfactant are added, and then a polyhydric alcohol is added and mixed by stirring for about 30 minutes to obtain a wheel rust remover.

The wheel rust remover thus produced has a high viscosity and a strong adhesion to the coated surface. Therefore, it easily adheres to the wheel surface and does not easily flow down, and since it can be applied thickly to the application surface, it has a high rust removal effect. At the same time, it is possible to remove oil and mud that have adhered to the wheels. Further, since the osmotic force is strong, it is not necessary to wash the dirt on the rust removal surface in advance, the rust can be efficiently dissolved, and it can be easily washed off with water after the rust removal work is completed.

Here, a method of using the wheel rust remover will be described. First, a rust remover is applied or sprayed on the target portion of the wheel with a brush, a brush, or a spray. Then, the rust part melts and gradually turns into purple, so it can be confirmed that the rust removing effect is exerted. In this state, the rust will run off, but it goes without saying that the deposit can be further dropped by applying water. All you have to do is dry it. Although this wheel rust remover is configured exclusively for the wheel, other parts of the vehicle where rust is occurring,
Needless to say, it can also be used for removing rust on vehicles other than vehicles.

EXAMPLES The weight of each component constituting the wheel rust remover according to the present invention was 1. Carboxylic acid or glycolic acid: about 25 parts Organic amine, amine hydroxide and ammonium hydroxide: about 25 parts 3. 3. Secondary alcohol ethoxylates and higher alcohols and ethoxylates and alcohol-based surfactants: about 2 parts 4. Polyhydric alcohol: about 10 parts 5. Ion-exchanged water: It was proved as the result of the experiment that it was most effective when it was made up to about 35 parts and put to practical use. Needless to say, there may be some difference in the weight ratio provided that at least an appropriate carboxylate or glycolate is produced.

Next, the method for producing the wheel rust remover according to the present invention is as follows: About 35 parts of ion-exchanged water is put into a tank made of resin (for example, polyvinyl chloride). 2. Next, about 25 parts of carboxylic acid or glycolic acid is added to and stirred for about 5 minutes with a stirrer at about 350 to 1000 RPM / min. 3. While continuing stirring, about 25 parts of organic amine, amine hydroxide and aqueous ammonia are added and stirred for about 20 minutes until the exothermic neutralization reaction is completed. At this time, PH (hydrogen ion concentration)
Check and adjust so that PH = 6 to 8 is neutral. Thus, a carboxylate or glycolate is produced. 4. Then, while further stirring, about 2 parts of the secondary alcohol ethoxylate, the higher alcohol, the ethoxylate and the alcohol-based surfactant and about 10 parts of the polyhydric alcohol were added until the solution became uniform (until almost transparent). ) Stir for about 30 minutes. It goes through the process of.

[0019]

As described above, the wheel rust remover of claims 1 and 2 has high viscosity and strong adhesion to the coated surface. Therefore, it easily adheres to the wheel surface and does not easily flow down, and since it can be applied thickly to the application surface, it has a high rust removal effect. At the same time, it is possible to remove oil and mud that have adhered to the wheels. In addition, since the penetrating power is strong, it is not necessary to wash the dirt on the rust removal surface in advance before the rust removal work, the rust can be efficiently dissolved, and after the rust removal work is completed, it can be easily washed off with water.
Moreover, since the wheel rust remover is a neutral liquid agent, it is highly safe and can prevent an unexpected situation due to work. The method for producing a wheel rust remover according to claim 3 can be easily produced in large quantities at low cost without increasing the scale of production equipment.
