JPS62214038A - Method for polishing automobile body and forming protective film - Google Patents

Abstract

PURPOSE:To form a protective film of good quality having a rich gloss, durability and weather resistance, by sufficiently removing extraneous matter of dirt, rust, etc. from surfaces of a car body thereafter applying fluid mainly composed of high molecular fluorine-contained resin. CONSTITUTION:A car body, after it is washed by water, performs a primary process to apply a detergent sufficiently removing extraneous matter of dirt, rust, etc. from surfaces of the automobile body. Thereafter, a secondary process is performed applying fluid mainly composed of high molecular fluorine- contained resin, and the body uniformly forms on its surface a film of the high molecular fluorine-contained resin. And said high molecular fluorine- contained resin film, which is closely attached intruding into a fine rugged part provided on the body surface, both corrects it to a smooth surface and exceptionally improves its brilliance. Further said formed film, which provides durability and weather resistance being maintained as a long time protective film, enables a large effect to be given for preventing the body from deteriorating.

Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to a "method for forming a polishing and protective film" for protecting and polishing the painted surface of the outer panel of an automobile body.
It is related to.

"Prior Art" and "Problems to be Solved by the Invention" In general, the painted surface of an automobile body is usually waxed to protect it from rain and the outside air and to give it a glossy finish. It is.

However, the wax is made of oil-based or wax-based materials, has weak physical properties such as wear resistance, and has large particles, so it does not have sufficient activity with the painted surface. As the waxed protective film does not get into the roughness, it tends to chip off early, fade, and attract foreign matter.If you do not repeat the troublesome waxing process frequently, the gloss and proper protective film will not be maintained. The problem is that it cannot be maintained.

The waxed protective film described above has the property of repelling rainwater because it is made of oil or wax.
After rainfall, the water drops form into circular water droplets on the film, and the circular water droplets act as a bending lens when exposed to sunlight, causing corrosion of the iron plate that is supposed to hold the noodles and promoting damage to the painted surface.

It is an object of the present invention to solve the above-mentioned conventional problems and to provide a new method for forming a glossy and protective film that forms a highly glossy and durable film.

``Means for Solving the Problems'' This invention achieves the above objectives by ``After washing the car body with water, as a primary process, dirt, rust, and other deposits on the surface of the car body are sufficiently removed using a cleaning solution. Thereafter, as a secondary process, a coating liquid containing a polymeric fluororesin as a main component is applied to uniformly form a coating film of the polymeric fluororesin on the surface of the vehicle body.''

"Examples" and "Operations" The present invention will be described in detail below with reference to Examples. First, a method for polishing and forming a protective film (hereinafter simply referred to as a film forming method) will be described in accordance with the procedure of an embodiment of the present invention applied to a passenger car.

・First, wash the car body with water to remove any deposits.

・Next, as a primary process, wipe the surface of the car body with a cleaning solution applied to a towel or the like to thoroughly wipe away dirt and rust on the surface of the car body that cannot be removed by washing with water. In addition, this primary processing includes oil, fat, limescale,
Pure Cleaner is used, which is odorless, transparent, non-foaming, non-polluting, soft-touch, and has strong decomposition and cleaning power that effectively dissolves stubborn dirt such as stains.

・Subsequently, secondary processing and 1- high polymer fluororesin (hereinafter referred to as
A coating liquid whose main component is Teflon is applied to a towel or the like and applied to the surface of the car body, forming a thin film of Teflon on the surface of the car body.

・Finally, finish with a dry wipe. If possible, the above processing can be repeated several times.

According to the film forming method of the present invention, the primary processing sufficiently removes dirt, rust, and other deposits to make the painted surface and other car body surfaces beautiful, and then the secondary processing coats the beautiful surface with Teflon. As a result, the fine particles of Teflon fully penetrate and adhere to the minute irregularities on the car body surface, making the car body surface extremely smooth without minute irregularities, and the surface Since a transparent Teflon film is applied to the surface of the vehicle, the vehicle body as seen by the viewer has a so-called ``shiny'' appearance with extremely high gloss.

Since the protective film formed by the method of the present invention is made of a Teflon film, it has the following advantages.

- Teflon coating has a low coefficient of friction, excellent physical rubbing force, and good adhesion to the surface of the car body, making it extremely suitable for the unique circumstances of automobile bodies that are exposed to the outside air while driving at high speeds. The film does not peel off or fade easily, has very little foreign matter attached to it, and can maintain a good film condition for an extremely long period of time. Therefore, unlike conventional waxes, there is no need to reapply at short intervals, and even if the gloss decreases over time due to foreign matter, the gloss level will immediately change if the film is damaged by washing with water or dry wiping. This makes daily car body management extremely easy.

- Also, since the Teflon coating has excellent heat resistance, even if the ceiling of the car body becomes hot due to outdoor parking in the summer, for example, the coating will not be damaged and a good protective coating can be maintained.

・Furthermore, Teflon and membrane (unlike conventional wax) do not repel rainwater and form water droplets, preventing the harmful effects of sunlight from damaging the steel plate parts of the car body and the painted surface. There is no danger of doing so.

It has the above excellent effects.

"Effects of the Invention" As explained above, according to the polishing and protective film forming method of the present invention, the glossiness of the outer panel parts such as the painted surface of the car body is significantly improved, and it also has durability and weather resistance. Because the high-quality protective film lasts for a long time, the troublesome conventional waxing process is no longer necessary, making daily car body maintenance extremely simple. There are also great effects such as maintaining the surface condition and base material of the vehicle body in good condition and preventing deterioration of the vehicle body.
