Description

Transparent liquid polish composition for automatic car wash {An compound use as a transparent riquid wax in automatic vehicle-washing devices}

The present invention relates to a transparent liquid varnish composition for use in automatic vehicle-washing devices.

In general, the liquid polish for conventional car washes is composed of liquid paraffin, nonionic surfactants and purified water, and a small amount of wax (lead), liquid paraffin, nonionic surfactants, and purified water.

ΔG = G _B -G _A

ΔG here: increased glossiness

G _A : Average value of 60 ° mirror surface glossiness of test piece before operation

G _B : Average value of 60 ° mirror surface glossiness of test piece before operation

3. Contact angle measurement test and evaluation method (Self test regulation)

3.1 Measuring Instruments

FACE CONTACT ANGLEMETER "CA-DT / A" of KYOWA INTERFACE SCIENCE.CO., Japan was used.

3.2 Test Method

(1) Install 25 mm x 75 mm coated specimens (KSM 2741 polished wax for automobiles. 7.2.1 (1) Specimen specified in the contact angle measuring device) and drop the droplet of 1.5 to 2.0 mm in diameter onto the specimen. Measure the contact angle within 3 to 5 seconds (the value at this time is the default contact angle).

(2) 1.0 ml of the composition of the present invention was dropped on a 25 mm × 75 mm coated specimen, and then polished by reciprocating up and down 10 times using a cloth, followed by drying.

After the specimen treated with the composition of the present invention was incubated in the measuring device, a droplet of 1.5 to 2.0 mm in diameter was dropped on the specimen and the contact angle was measured. (The value at this time is used as the initial contact angle.)

At this time, the contact angle is measured within 3 to 5 seconds after the drop of water, and the reason is to reduce the measurement error of the contact angle due to the surfactant contained in the composition of the present invention.

(3) Rinse the specimen measuring the initial contact angle in water flowing at 500㏄ / sec (representing the water as fresh water) for 2 ~ 3 seconds and dry it. Because the sample and some water are sprayed on the car body during the polishing process, the test is carried out under similar conditions, and the test results in this condition are similar to the gloss and water repellency effect on the car body painting surface.

Measure the contact angle of the dried specimen in the same way as the initial contact angle measurement method. (The value is expressed as the contact angle after washing with fresh water.)

3.3 Evaluation Method

The larger the contact angle of the water droplets in the same amount, the smaller the surface area on the painted surface, so that the water droplets are easily removed by the wind of the automatic washing machine drying process.

On the contrary, the smaller the contact angle of the water droplets in the same amount, the larger the surface area of the water droplets on the painted surface, resulting in an uneven flow of water, which is not easily removed by the wind of the automatic car wash drying process. It requires a drying process.

Therefore, by measuring the basic contact angle, the initial contact angle, the contact angle after fresh water washing by the test method of (1), (2), (3), respectively, the numerical value of the superior contact than the basic contact angle.
