Apply oil-based wax, such as paraffin wax or acrylic wax, to the car body before shipment to prevent contamination and damage to the appearance of the car body (that is, the coating of the car body) due to the adhesion of dust and iron powder. That is being done. This oily wax is removed from the vehicle body by solvent washing and water washing before delivery to the user.

段によって代替することが望まれている。However, the appearance protection function of the oil-based wax is not always sufficient, and there has been a problem that repairing a contaminated or damaged automobile body requires a lot of cost. In addition, the oil-based wax must be applied periodically (once every three months) to the stock of a car, and the cost of maintenance including equipment for that purpose has also become a problem. Further, since the trauma prevention cover also causes an increase in the number of steps in the assembling process, it is desired that the cover be replaced by other means at lower cost.

At this time, a special protective cover is attached to the automobile body. Even if it is not attached to the device, it can be protected from abrasion caused by contact with parts and tools by the coating film of the protective paint.

ある。The completed automobile is shipped without removing the protective paint, and is transported and stocked with the protective paint applied. In the meantime, the coating of the protective coating protects the coating of the automobile body from scratches, acid rain, bird and insect droppings, sand, dust, iron powder and the like. The effectiveness of the protective coating lasts about six months, but usually this period is sufficient as a stock period before the car is handed over to the user.

る場合に比べて極めて簡単に行うことができる。Before the vehicle is delivered to the user, the protective paint covering the vehicle body is removed. The removal of protective paint is carried out by peeling by hand with a cut in a part of the paint film or by a high-pressure car washer.
In either case, the method can be performed much more easily than in the conventional case of removing oily wax.

のコストを削減することができる。That is, in the conventional oil-based wax removal, kerosene and steam are used in the case of paraffin wax.
In the case of acrylic wax, an alkaline solution is used. In any case, wastewater mixed with wax and a washing solvent is separated into waste and wastewater by an oil-water separation method or a coagulation sedimentation method using chemicals. It was necessary to incinerate the waste and biologically treat the wastewater. On the other hand, the protective paint of the present invention does not require the wastewater treatment not only when peeling is performed but also when a high-pressure car washer is used, so that the cost can be reduced.

The protective coating is made of acrylic emulsion resin
And water, which is a solvent, as a main component.
Added dispersible silicone oil and water-dispersible UV absorber
Because it is, factory together it is possible to prevent the damage of the coating of the car body during injury and after shipment transportation of the coating of the car body and in the stock during the assembly process, especially automobile body after shipment Is exposed to sunlight for a long time
Water-dispersible UV absorber as an additive
Effectively prevents deterioration and discoloration of the body due to ultraviolet rays
it can. In addition, the water-dispersible silicone oil is added to the protective coating.
The peelability enhancing effect based on yl added, it is possible to peel off very easily pull the protective coating which becomes unnecessary before delivery to the user from the automobile body by hand or high pressure car wash, during its peeling, automobile body May damage
There is no need to perform wastewater treatment using large-scale equipment, which was required in the past. Its these results, while significantly reducing the time and cost, it is possible to reliably achieve the appearance protection of the car body.
