The impact resistance of automotive solar film is an important performance index reflecting its flexibility, and it is an important basis for evaluating the performance of solar film explosion-proof performance. In this paper, the Labthink FIT-01 film impact tester is used to test the anti-pendulum impact energy of automotive solar film samples, and the test principle, equipment parameters and test process are described. When comparing the impact resistance of packaging materials, enterprises should use the same diameter of the punch to prevent the impact of the test results due to the difference in the diameter of the punch. The specific test methods can refer to the specific content described in this article. Meaning The automobile solar film is a film-like object attached to the front and rear windshields, side windows and skylights of the vehicle, and this film-like object is also called a car foil or an explosion-proof film. Its main function is to prevent the person from injuring, blocking ultraviolet rays, blocking part of heat and anti-glare caused by sudden burst of glass, and at the same time, according to the one-way perspective performance of the solar film, the purpose of protecting personal privacy is achieved. In general, the higher the anti-pendulum impact energy of the automotive solar film, the better the impact resistance of the automotive solar film, the better the flexibility, and the solar film can be effectively explosion-proof. If the solar film attached to the glass of the automobile is subjected to an impact or impact by an external force, if the impact resistance is poor, it is easy to cause a sudden explosion of the glass under the impact or impact, and thus a good accident is caused. Impact performance is one of the essential properties of automotive solar film materials. Figure 1 Automotive solar film 2. Test sample A special solar film for a car brand. 3. According to the standard At present, the domestic automotive solar film material anti-pendulum impact energy detection standards can refer to GB 8809 "plastic film anti-pendulum impact test method." 4. Test equipment The test equipment for detecting the anti-pendulum impact energy of the sample is the FIT-01 film impact tester independently developed by Jinan Languang Electromechanical Technology Co., Ltd. 4.1 Principle of the test The basic test principle of this test is energy conservation, and ignores the energy consumed by air and other resistance during the test. During the test, the pendulum is released from a certain height, so that the punch breaks through the sample at a certain speed, and continues to move upwards to a certain height and then fall back. The anti-pendulum impact energy of the sample is obtained by testing the energy change of the punch before and after breaking the sample. Figure 2 FIT-01 film impact tester 4.2 Equipment parameters The impact energy is 1 J, 2 J, 3 J (expandable to 5 J) with a resolution of 0.001 J. The diameter of the punch is divided into 25.4 mm, 19 mm, and 12.7 mm. The remaining non-standard sizes can be customized. The diameter of the sample jaws on the equipment is 89 mm and 60 mm, respectively. The range is adjustable, and the electronic measurement can easily and accurately test under various test conditions. The pneumatic clamping of the specimen, the pneumatic release of the pendulum and the horizontal adjustment aid system effectively avoid systematic errors caused by human factors. The system automatically counts the test data and visually presents the test results to the user. Support LystemTM laboratory data sharing system, unified management test report and test results. 4.3 Scope of application (1) This equipment is suitable for the accurate measurement of anti-pendulum impact performance of plastic film, sheet, composite film, metal foil and other materials. It can also be used for anti-pendulum impact performance test of paper and paperboard, such as cigarette paper aluminized paper. , Tetra Pak packaging aluminum plastic paper composite materials. (2) The equipment meets a number of national and international standards: GB 8809, ASTM D3420, NF T54-116. 5. Test process (1) Randomly cut 10 pieces of 10 cm × 10 cm specimens along the width direction of the surface of the sample film, and place the sample at a temperature of 23 °C ± 2 °C and 45% RH ~ 55% RH. 4 h and tested in this environment. (2) Test the thickness of the sample with a thickness gauge, test 10 points, and take the arithmetic mean of the test results at 10 points. (3) Select a punch with a diameter of 12.7 mm for the test. The diameter of the sample is 89 mm. (4) Perform equipment calibration according to the requirements of the equipment. (5) Fix the sample flatly into the sample holder of the equipment. The sample should not have wrinkles or excessive tension. (6) Enter the test interface, fix the pendulum, click the test button, the pendulum will automatically fall, impact the sample, and the device will show the anti-pendulum impact energy of the sample. (7) Test the sample against the pendulum impact energy in turn, and check the equipment test results. 6. Test results The average anti-pendulum impact energy of the 10 automotive solar film samples tested in this paper is 1.854 J. 7.
