Description

[0002] Thermoplastic elastomer phase change material is a composite phase change material prepared by utilizing the characteristics of thermoplastic elastomer. Specifically, the researchers cross-linked the soft segments in the block with the molecules and obtained the composite phase change material by cross-linking the molecules through the van der Waals force. This material combines the excellent properties of thermoplastic elastomers and the thermal regulation function of phase change materials, and has broad application prospects. The light aging test of thermoplastic elastomer (TPE) phase change material is used to simulate the performance changes of the material under long-term light (such as sunlight, ultraviolet light, etc.), so as to evaluate its durability and stability in the actual use environment.

At the same time, the material fixing component 3 cooperates with the material input conveyor belt 5 and the material output conveyor belt 6, so that the device can realize automatic sample fixing, avoiding sample contamination or damage outside the test caused by staff contact, thereby affecting the experimental results, and the material fixing component 3 can also straighten the sample during the experiment without affecting the test, to prevent the sample from softening and deforming when heated, thereby changing the surface state, structure or internal stress distribution of the material, and further affecting its performance in the light aging test. The control panel 9 is connected with components such as the humidity controller and temperature controller inside the device, and it can control each component in the device to ensure that the device operates in a scientific and efficient manner.

[0049] Further, the material fixing component 3 includes:

[0050] The fixed frame 31 is fixedly mounted on the upper surface of the middle bearing plate 2, and two sets of rotating pulleys 32 are rotatably arranged on the inner side thereof, wherein one set of rotating pulleys 32 is fixedly mounted on the output shaft of the motor, and the motor is fixedly embedded in the middle bearing plate 2, and sliding belts 33 are meshedly mounted on the outer sides of the two sets of rotating pulleys 32, and fourteen sets of rotating bearing blocks 34 are fixedly mounted on the sliding belts 33, and twelve sets of the rotating bearing blocks 34 are fixedly mounted on material clamping assemblies 35.

[0052] As a preferred embodiment, the twelve groups of material clamping assemblies 35 correspond to the twelve groups of sliding positioners 36. When the experiment starts, the twelve groups of sliding positioners 36 need to correspond to a group of rotating supporting blocks 34 carrying the material clamping assemblies 35, so as to ensure the distance angle and other conditions between the sample on the material clamping assembly 35 and the light simulation assembly 4. The other two groups of rotating supporting blocks 34 are set to have equal distances between the rotating supporting blocks 34, so that the device can be easily adjusted in position.

[0053] Further, the material clamping assembly 35 includes:

[0054] The first fixed plate 351 is fixedly assembled on the upper surface of the corresponding rotating bearing block 34. Four groups of lifting rods 352 are fixedly assembled on the upper surface of the first fixed plate 351. The four groups of lifting rods 352 are fixedly embedded on the second fixed plate 353. The second fixed plate 353 is horizontally arranged, and four groups of supporting blocks 354 are fixedly assembled on the upper surface of the second fixed plate 353. The upper surface of the four groups of supporting blocks 354 are fixedly assembled with a third fixed plate 355. Four groups of telescopic blocks 356 are slidably arranged on the side of the third fixed plate 355, and each group of telescopic blocks 356 is fixedly assembled on the corresponding driving block 357. The driving block 357 is fixedly assembled on the front end of the extension hydraulic cylinder 358. The extension hydraulic cylinder 358 is fixedly assembled on the lower surface of the third fixed plate 355.

[0055] As a preferred embodiment, the setting of the lifting rod 352 can adjust the relative height of the sample to a certain extent, thereby changing its relative distance with the illumination simulation component 4 while ensuring that the illumination simulation component 4 remains unchanged, thereby forming a comparison and facilitating the exploration of material properties.

[0056] Furthermore, a fixing bolt 359 is threadedly mounted on the upper end of the driving block 357, and a material damage prevention block 3510 is fixedly mounted on the lower end of the fixing bolt 359. The material damage prevention block 3510 is arranged between the driving block 357 and the corresponding telescopic block 356;

When the sample softens and deforms due to heat, and its surface state, structure or internal stress distribution changes, the corresponding extension hydraulic cylinder 358 will slowly extend, allowing the sample to stretch without changing its properties, thereby preventing its performance in the light aging test from being affected.

[0058] Furthermore, the illumination simulation component 4 includes:

[0059] The driving motor 41 is provided with two groups in mirror image, and both are fixedly mounted on the upper surface of the middle bearing plate 2. The output shafts of the two groups of the driving motors 41 are respectively fixedly provided with a lifting transmission group 42 and a rotating transmission group 43, and the lifting transmission group 42 and the rotating transmission group 43 are respectively fixedly embedded in the fitting grooves 421 opened on both sides of the dustproof protective shell 44. The inner side of the dustproof protective shell 44 is fixedly provided with a light adjustment component 47, and a self-driving slider 45 is slidably provided above the self-driving slider 45, and a light simulator 46 is fixedly mounted on the lower end of the self-driving slider 45;

[0060] As a preferred embodiment, the corresponding drive motor 41 starts the transmission through the lifting transmission assembly 42, so that the relative height of the light simulator 46 can be changed, thereby simulating the change of the sun's altitude at different positions. The corresponding drive motor 41 starts the transmission through the rotating transmission group 43, so that the light simulator 46 can simulate the change of the sun's angle at the same location in a year. The sliding of the self-driving slider 45 on the dustproof protective shell 44 can simulate the change of the sun's direct point in a day. The sliding of the self-driving slider 45 and the cooperation of the light adjustment assembly 47 can simulate the change of factors such as light intensity in a day, so that the device can simulate the real situation of light to the greatest extent, and further ensure the accuracy of the test results.

[0061] Further, the lifting transmission group 42 includes:

[0062] A sliding block 422 is slidably assembled in the corresponding fitting groove 421, and is threadedly fixed on the output shaft of the corresponding driving motor 41. A driving gear 424 is coaxially fixed to the outer side of the sliding block 422. A fixed rack 423 is meshedly provided on one side of the driving gear 424. The fixed rack 423 is fixedly assembled in the corresponding fitting groove 421;

[0063] As a preferred embodiment, the sliding block 422 is threadedly fixed on the output shaft of the corresponding driving motor 41, which can ensure that when another group of driving motors 41 drives the lighting simulation component 4 to rotate under the action of the rotating transmission group 43, the lifting transmission group 42 will not work to change the relative height of the lighting simulation component 4 (the lighting simulation component can be rotated in a small range of only 180°).

[0064] Further, the rotation transmission group 43 includes:

[0065] The sliding block 2, which is arranged in a mirror image with the sliding block 422, is slidably embedded in the corresponding fitting groove 421 and coaxially fixedly assembled on the output shaft of the corresponding driving motor 41.

[0066] Furthermore, the light adjustment component 47 includes:

[0067] The first adjustment gear 471 and the second adjustment gear 472 are both fixedly assembled inside the dust protection shell 44, and a passive gear 473 is meshed between the first adjustment gear 471 and the second adjustment gear 472, and the passive gear 473 is rotatably arranged inside the self-driving slider 45, and the passive gear 473 is coaxially fixed on the intensity adjustment rod of the light simulator 46;

[0068] The first adjusting gear 471 and the second adjusting gear 472 are both provided with a toothed section 474 and a flat section 475;

[0069] As a preferred embodiment, when the lighting experiment begins, the relative height of the lighting simulation component 4 is determined according to the experimental conditions. The lighting simulation component 4 must first simulate the rising and setting of the sun in a day. The self-driving slider 45 will run from the rightmost end to the leftmost end, and in the initial state, the lighting intensity and the emission temperature of the lighting simulator 46 are the lowest. As the device runs, the passive gear 473 rotates under the action of the tooth segment 474 of the first adjusting gear 471, and controls the lighting intensity and the emission temperature of the lighting simulator 46 to increase. When it reaches the highest point, it simulates the highest point of the lighting intensity and the emission temperature in a day, and then the passive gear 473 rotates under the action of the tooth segment 474 of the second adjusting gear 472, and controls the lighting intensity and the emission temperature of the lighting simulator 46 to decrease until it reaches the leftmost side, ending the simulation of a day, and then in the case of night simulation, the components in the device return to the initial position, and fine-tune the angle of the lighting simulation component 4 to simulate the different lighting angles every day, and repeat the above operations until the experiment ends.

[0070] A light aging test method for a thermoplastic elastomer phase change material comprises the following steps:

[0071] S1. Place a thermoplastic elastomer phase change material sample of appropriate size on the material input conveyor belt 5. As the material input conveyor belt 5 runs, the material fixing assembly 3 is started to fix the sample running to a suitable position;

[0072] S2. After twelve sets of samples are fixed on the material fixing assembly 3, the sealed opening and closing door 7 is closed by driving the hydraulic rod 8, and then the light simulation assembly 4 is started;
