Next, the coating is directly applied to the surface of the workpiece by means of knife coating, transfer, [P or screen printing, etc., in this embodiment, screen printing is exemplified, but not This is limited to this. The coating composition is dried on the surface of the workpiece by the coating of the workpiece having the coating composition on the surface of the workpiece in the environment of 60 120c. And in the workpiece table into a three-dimensional coating. Among them, the bake-out operation may also be carried out by ultraviolet (UV) 201141969 irradiation to complete the drying and curing process of the coating composition. Then 'adhesion test, gloss test (gl〇ss city), abrasion resistance test (RCA this coffee - test), eraser abrasion resistance test (the workpiece with the coating composition on the surface) The eraser abrasion test), the alcohol abrasion test 'hardness test' and the high temperature and high temperature test (humidity and temperature test) and other elastic three-dimensional coating characteristics test, the results are shown in Table 1. Table 1 Test results Adhesion test 5B Gloss test 1.3 Abrasion resistance test 100 times Eraser abrasion resistance test 2000 Back to alcohol-resistant friction test 150 times hardness test 尚 Still temperature ifj wet test appearance no abnormality, 5 Β As shown in Table 1 It is shown that the adhesion test is carried out by the attached force tape test method specified by American Society of Materials Testing and Materials (ASTM) D3359. This method uses a knife to cut the test square on the elastic three-dimensional coating and then clean the surface with a soft brush. Next, 3M 600 tape manufactured by 3M Company was attached to the square, and pressure was applied to the tape with an eraser to make the tape adhere to the test square on the surface of the workpiece. Then take 9 〇. Corner pull-up glue 201141969 Belt, the test square with poor adhesion on the surface of the workpiece will be adhered to the surface by the adhesive tape. Then attach the tape to the square and then 9 inches. The step of pulling the tape at the corner is 2 times. After that, the situation of the detachment on the surface of the test box is examined and calculated, and the dense force of the miscellaneous reading (4) on the surface of the workpiece is divided into (9) to the six grades of the material. 0B represents the removal rate of more than 65%, and m represents Μ~Na's removal rate, 2B represents 15~35% of the removal rate 'offender represents $yun's removal rate' and represents less than 5% of the removal rate, and 5B represents the removed rate The removal rate is in the result of the adhesive bribe, and the adhesion between the composition and the surface of the workpiece can reach the standard of 5B, that is, the removal rate of the elastic three-dimensional coating from the surface of the workpiece is zero. The coating composition disclosed in the present invention can be tightly bonded to the surface of the workpiece without the occurrence of detachment. - The gloss test was tested in accordance with the method specified by the American Society for Testing and Materials (Asm) D523, which is 6G. A specular reflectance measuring instrument (manufactured by ZEHNTOER Corporation) was tested. The wire test value of the elastic three-dimensional coating on the surface of the workpiece is 丨3, and the result is within the range of the qualified judgment. Next, the abrasion resistance test (R.C.A. abrasi〇n test) was carried out in accordance with the method specified by the American Society for Testing and Materials (ASTM) F2357. The abrasion resistance test was performed on a rca abrasion tester with a 175 gram 阙 and a 2_MK tape made by N_an Gongqi. Then, the workpiece with the coating composition on the surface is fixed on the RCA abrasion testing machine, and the test rod is adjusted to reach the level, and then the abrasion resistance test is performed, so that the paper belt 201141969 is rubbed with the elastic three-dimensional coating, and the number of revolutions is determined. Let's look at the effect of the coating on the grain. Then, observe the elastic three-dimensional coating on the surface of the workpiece with a 60-fold microscope. In the results of the abrasion resistance test, after the workpiece having the coating composition on the surface was subjected to 100 times of abrasion, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating, and therefore the elastic three-dimensional coating was still not completely silked. This results show that the coating composition disclosed in the present invention has good wear resistance characteristics. In the other - _ silk test towel, the movement, the elastic yarn test (erasefabrasiQn test). It is attached to the test instrument's job pole with a 5 gram weight code and an eraser (EF74) and the workpiece with the coating composition on the surface is fixed to the test instrument' followed by a test distance of 5 cm. The eraser and the abrasion test were carried out in a measurement method of 6 minutes back and forth. After the 2_ back test, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating. Alcohol-resistant hybrid test (aleGhGl abrasi () n (four) Fine American Broken Test Association (ASTM) D1308 method is carried out. It is based on the test rod of the alcohol-resistant friction device and the 500 gram weight breaking code and a immersion percentage % of the alcohol gauze. Then the table = with - the composition of the paint composition is fixed on the alcohol-resistant friction tester, with a test distance of 5 cm: 60 round trips per minute for the alcohol-resistant friction test. After (9) σ After the test, the surface of the workpiece was not observed to be exposed outside the elastic three-dimensional coating. Therefore, the results of the above (paper tape type) abrasion resistance test, the eraser abrasion test and the alcohol-resistant abrasion test are disclosed. The paint composition forms a bullet on the surface of the workpiece! The raw three-dimensional coating has quite good wear resistance characteristics. Then, according to the method of the American Society for Testing and Materials (ASTM) tearing, the lamp hardness is changed to her ess (4). The first is to make a wrong refill (10), the leg view, manufactured by Mitsubishi Corporation) to reveal the secret to α6 cm. The core of the _ core and the sand are at an angle of 90 degrees. The core of the erroneous pen is worn to a flat surface with no gaps by the sandpaper. Newton will be equipped with a pencil at 45. In the fine hardness tester, the bribe _ on the transfer table _ elastic three-dimensional coating is on the condition of the test load. In this hardness test, the hardness of the refill is that the wrong pen cannot be scratched and formed on the surface of the workpiece (4). Therefore, the coating composition disclosed in the present invention has a hardness of the coating to the hardness standard of the coating on the surface of the workpiece. After the workpiece with the coating composition on the surface is subjected to high temperature and high humidity test (humidity and temperaturc test), the workpiece having the coating composition on the surface is placed at a temperature of 85 degrees Celsius, and the relative mystery is 9 (). hour. Then, the workpiece having the coating domain on the surface is taken out from the above-mentioned environmental towel, and left to stand at room temperature for one hour, and then simultaneously (four) test, thereby testing whether the high temperature and high humidity environment is related to the coating composition. The adhesion between the surfaces of the workpiece affects.
