Abstract

An interface protective paint for automobile body and the painting method of the same. This method primarily uses protective paint comprises of an organosiloxane oligomer, a catalyst (activator), a silane compound and a titanium compound. By using painting and wiping tools, the said protective paint is painted on the designed area of the automobile body with a one coat process to give a film thickness below than 5μm. Afterwards, the painting process is repeated to repeatedly coat a protective paint on the painting area. And the painting and wiping step are repeated until there is no any interference marks left on the painting surface. The paint is then followed by a drying step through air drying or forced drying process to form a protective painting of durable, no wax needed and non finger print or wiping marks left protective layer on the painting area.

Description

200821363 IX. Description of the invention: [Technical field of the invention] The automobile body interface protection coating of the invention and the coating method thereof, especially a kind of solvent-free composition, which is non-toxic to the human body and the environment, and

5 It will produce the durability of applying wrinkles and fingerprints, and the single liquid type: the vehicle body protection coating and its coating method. Group I [Prior Art]

It is known that cars have become the most commonly used and most convenient transportation workers, and i.5, especially cars, are high-priced goods. Most of the cars have the convenience of 10, in addition to enjoyment. Strive to maintain the depreciation of the product', including regular maintenance of the mechanical parts such as the engine, as well as regular cleaning and waxing on the exterior coating part of the car 5. The above-mentioned waxing work has superior water repellency and brightness at the beginning of the automobile, but it is necessary to complete the waxing work by hand rubbing to exert a very strong I5 maintenance effect, but such an effect can only maintain about After 3 months, even after manual waxing, there is no effect or can not achieve very good maintenance. Moreover, after the wax that has been blown is dissolved, it will adhere to the glass of the car, and the shortcoming of the line of sight becomes blurred. ^ 20 In order to improve the above-mentioned defects, in Japan, the special opening 2〇〇〇—32587 = the body coating part, the smear (4) grease and the polymer coating on the exterior of the car body are coated with a base solvent and a stone mantle:乂This coating is 'or mixed with two different types of different ingredients: Apply to the smear layer made of enamel resin. Although the above method can improve the above-mentioned defects, there are also problems of 4 200821363: 1. In order to use two or more two-liquid type mixed paints, it is necessary to mix and match the working time and match each painting operation. It is necessary to use the continuous operation of ^1, not only the steps are complicated, but also easy to produce mixed imbalance. 2. Because the mixed paint contains organic solvent, due to the change of time, the rain

Jude up, down, left, and right without leaving spots =::=:=' Then + minutes, the amount of rubbing tools and effective coating to shorten the time, and, dry into the secondary - step and other factors, The p-cutting 瑕疵 is its advantage 6 in the smear 20 200821363 f 2: the protective coating applied due to the passage of time will be harder and harder to work harder, so this step is better at 30 Better in minutes. ς ^The smear tool used for the step, preferably with a thickness of 1 To the cloth, especially the ultrafine fibers, such as the extremely fine cloth made of fine polyester fiber, and the thick cloth is used to wipe the X. The coating amount is coated and wiped. The amount of protective coating used in the cloth and the area of the coating can be used to calculate the remaining amount of the coating material.

Next, in the coating tool, mainly after the first coating step is completed, the coating material is again applied by using a suitable amount of the protective coating of the present invention, and in the same coating operation, Repeat the application. The interference pattern remaining at this time should be wiped repeatedly until there is no interference fringe. After the protective coating is applied repeatedly, the effective coating amount of the predetermined body coating area is preferably 5g/ffi2 or less, in order to prevent interference fringes, and to promote drying, and to ensure a uniform thick film degree. . The coating tool described above is preferably carried out after 1 minute to 12 minutes after the completion of one coating step, so as to have a time for performing a stanol reaction, thereby producing a uniform and hard protective film layer in the vehicle. The preset interface of the body interface. In the drying step, in order to dry the applied protective coating, after performing the primary and reverse coating steps in all the coating ranges, the protective coating layer may be formed by drying the protective coating through a natural drying or forced drying process. In the above-mentioned drying process, air cannot flow directly into the room. Preferably, the air conditioning equipment should be installed and placed for one to two hours or more, preferably for more than three hours, and for 15 minutes even for the forced drying process. 15 200821363 After 30 minutes to 60 minutes of natural drying, use a hot air dryer, an infrared long wave dryer, an infrared short wave (far infrared) dryer, etc., and the temperature in the tank in the dryer is 50 Ϊ to 150 °. Preferably, C is preferably from 60C to 70°C, preferably from got to 7ITC, for 5 minutes to 560 minutes, or preferably for about 15 minutes. By using the automobile body interface protection coating of the invention and the coating method thereof, the protective film layer is coated on the rut, so that the fingerprint does not adhere to the vehicle body, and no interference pattern is generated, and the solvent can be used without using the solvent. It can be easily used and has durability. Therefore, the protective film layer of the present invention is coated on the external interface of the vehicle body, and it is not necessary to perform waxing after each car wash.

In the same way, according to the quantity, different samples can be used to prepare sample 4 to sample 15 · In addition, test for dry touch time, hardenability, pencil hardness, fingerprint adhesion, adhesion, and repeatability . The results were tested and compared with the influence of the amount of the catalyst, the influence of the ruthenium compound, and the influence of the titanium compound in 200821363. Each of the above tests was carried out at room temperature of 25 ° C, and the effective coating amount of each sample was 5 g/m, and a standard coating plate for coating for secondary application was used. First, touch the drying time and measure the time of non-adhesion by finger contact. Then, for the hardenability, after the toner was applied for two hours after the application, the toner was wiped off with a full cotton cloth. The following six are the meanings of the symbols in the comparison tables, 〇: completely removed, △: slightly residual, X: cannot be removed. Then, after the pencil hardness was 24 hours to 7 days, it was evaluated in accordance with the cut hardness (pencil method) of JIS K5655 5-4. In addition, the adhesion test of the fingerprint is to use the fingertips for 3 seconds to evaluate according to the attached fingerprint. The meanings of the symbols in the following tables, 〇: no adhesion, △: easy to erase, X: difficult to erase. Adhesion was evaluated by the test of J1SK5600 5-6. The repeated application test was repeated after 15 minutes of application, and the wipe was applied by observation, feeling, and visual evaluation, and the transparency and smoothness of the coating film. Further, the marks in the respective tables were evaluated on the coated film once applied or on the coated film which was repeatedly applied. 〇: Easy, △: The sheath was difficult, and X·· was impossible. In the above examples, the effect on the amount of catalyst: As shown in Table 5, when the catalyst is added to the coating material, the amount added will change according to the amount added, and when the amount of the catalyst is small (for example, sample 4), With the hardening time, the hardness of the coating material is lowered. Conversely, when the amount of the catalyst is large (for example, sample 7), it is difficult to repeatedly wipe the coating material. Further, the heptane oligomer-100 weight portion and the amount of the catalyst are preferably the surface of the weight of 〇·5~3〇. 23 200821363
