Description

Technical Field

[0001] This application relates to the field of weather resistance testing technology, and more specifically, to an accelerated testing device for the long-term stability of anti-aging high-stability masterbatch. Background Technology

[0002] Masterbatch, also known as colorant or colorant granules, is a new type of special colorant for polymer materials, also called pigment preparation. It is mainly used in plastics. Masterbatch consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin, and can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the colored resin or product. After production, masterbatch needs to be tested for weather resistance. Weather resistance testing is a comprehensive testing method that assesses the ability of materials or products to resist the effects of climatic factors such as light, temperature, humidity, rain, and salt spray under long-term exposure to natural or artificially simulated environmental conditions, in order to determine their durability, stability, and service life. The core of weather resistance testing is to predict the aging behavior of materials in actual use, such as fading, cracking, chalking, and decreased strength, thereby providing a scientific basis for product development, quality control, and market access. It is widely used in many industries such as automobiles, construction, electronics, coatings, plastics, and rubber.

[0003] In existing technologies, when testing the weather resistance of masterbatches, multiple separate devices are mostly used simultaneously to test the masterbatches' resistance to different properties such as light, temperature, humidity, rain, and salt spray. This requires a large number of devices, is complex to operate, and is expensive. There is a lack of a multifunctional weather resistance testing device that can integrate multiple items in the weather resistance test, which makes it difficult to reduce the number of operation steps and lower costs when testing the weather resistance of masterbatches.

The worm thread 505 meshes with the back of the worm wheel 405. A sealing assembly 6 is provided above both the first and second auxiliary chambers 301 and 303. The sealing assembly 6 is used to seal the first and second auxiliary chambers 301 and 303, thereby protecting the equipment inside the first and second auxiliary chambers 301 and 303 during other tests. The sealing assembly 6 includes a sealing insert plate 601, which is arc-shaped and fits against the outer surface of the test chamber 1. A connecting piece 602 is fixedly connected to the outer surface of the sealing insert plate 601. An electric push rod 603 is fixedly connected to the bottom of the connecting piece 602. Connected to the output end of the electric push rod 603, there are two sets of sealing components 6. The electric push rods 603 in the two sets of sealing components 6 are fixedly connected to the back of the first auxiliary compartment 301 and the second auxiliary compartment 303, respectively. The sealing plates 601 in the two sets of sealing components 6 are inserted into the top of the first auxiliary compartment 301 and the second auxiliary compartment 303, respectively. The inner surfaces of the first auxiliary compartment 301 and the second auxiliary compartment 303 are provided with slots and upper openings for the sealing plates 601 to be inserted and sealed. The inner surface of the detection compartment 1 is equipped with a spray assembly 7 for corrosion resistance testing. The spray assembly 7 can simulate the erosion effect of rainwater and test the detection compartment 1 by filling it with high-temperature and high-humidity gas or salt spray water vapor to conduct wet heat aging, salt spray corrosion, and rainwater erosion tests. The outer surface of the compartment door 307 is equipped with a cleaning assembly 8 for cleaning the observation window 308 to ensure observation effectiveness. The cleaning assembly 8 can clean both the inner and outer surfaces of the observation window 308 simultaneously to ensure the cleanliness of the observation window 308.

[0025] In practical use, the above-mentioned equipment is first opened by opening the door 307 and placing the masterbatch to be tested on the placement tray 402 inside the testing chamber 1. Then, the door 307 is closed to seal the testing chamber 1. At this time, the masterbatch is subjected to ultraviolet aging test and xenon lamp accelerated aging test by the lamp assembly 306. By activating the two electric push rods 603, the connecting plate 602 is driven to raise and lower the two sealing plates 601 in the first auxiliary chamber 301 and the second auxiliary chamber 303 respectively, thereby connecting the first auxiliary chamber 301 and the second auxiliary chamber 303 with the testing chamber 1. When the first auxiliary chamber 301 is connected to the testing chamber 1, the cooling equipment 302 is activated to cool the masterbatch. When the second auxiliary chamber 301 is connected to the testing chamber 1, the cooling equipment 302 is activated to cool the masterbatch. When connected to the testing chamber 1, the masterbatch is heated by starting the heating device 304. The masterbatch is then subjected to high and low temperature cycle testing by controlling the alternation of hot and cold. During the test, the motor 502 is started, which drives the rotating shaft 503 to rotate. When the rotating shaft 503 rotates, it drives the worm screw 505 to rotate the worm wheel 405. The rotation of the worm wheel 405 drives the rotating rod 404 to rotate in the shaft support 403. The rotation of the rotating rod 404 drives the chain condition 406 to drive the rotating column 401 to rotate. The rotating column 401 drives the placement tray 402 to rotate, which in turn drives the masterbatch on the placement tray 402 to rotate slowly, thus facilitating uniform testing of the masterbatch.

[0026] Example 2, see Figures 1-10The spray assembly 7 includes an annular tube 701, which is hollow and ring-shaped. A nozzle 702 is fixedly connected to the inner surface of the annular tube 701, and the nozzle 702 is located on the inner ring of the annular tube 701 and tilted downwards. Four sliders 703 are fixedly connected to the outer surface of the annular tube 701, respectively located on the front, back, left, and right sides of the annular tube 701. An annular slide rail 704 is slidably connected to the outer surface of each slider 703. A groove is provided on the outer side of each slider 703 to connect with the annular slide rail. The annular slide rail 704 is fixedly connected to the inner surface of the detection chamber 1. A water inlet 705 is fixedly connected through the top of the detection chamber 1, allowing connection to an external water source. The water inlet 705 is connected to the annular pipe 701 via a hose. Three air inlet valves 706 are fixedly connected to the back of the detection chamber 1, used to connect to pipes to allow the release of high-temperature, high-humidity gases or salt spray from the outside. Water vapor and other test gases are introduced into the test chamber 1 to test the masterbatch. A drain valve 707 is fixedly connected to the bottom of the base 2. The drain valve 707 is used to drain the sprayed liquid. A water circulation system is connected and installed between the drain valve 707 and the water inlet 705 to facilitate continuous spraying. The spray assembly 7 also includes a reciprocating screw 708, which is fixedly connected to the outer surface of the rotating shaft 503. A screw nut 709 is threaded onto the outer surface of the reciprocating screw 708. The rotational energy of the reciprocating screw 708... The screw nut 709 is able to move back and forth. A connecting rod 710 is fixedly connected to the front of the screw nut 709. The connecting rod 710 is L-shaped. A pulling piece 711 is fixedly connected to the upper end of the connecting rod 710. The pulling piece 711 passes through and slides through the right side of the detection chamber 1. A limit sleeve 712 is slidably connected to the outer surface of the pulling piece 711. The limit sleeve 712 is fixedly connected to the right side of the detection chamber 1. A hinge 713 is hinged between the pulling piece 711 and the slider 703. The hinge 713 is hinged to the slider 703 located at the rear.

[0027] When the above equipment is used to test the masterbatch against rainwater erosion, an external water source is first connected to the water inlet 705 via a pipe. After entering the water inlet 705, the water is transported through a hose to the annular pipe 701 and finally sprayed out from the nozzle 702, simulating rainfall to test the masterbatch's resistance to rainwater erosion. The water is discharged through the drain valve 707 at the bottom of the base 2. Connecting a water circulation system between the drain valve 707 and the water inlet 705 facilitates continuous spraying and saves water. When the motor 502 drives the rotating shaft 503 to rotate, the rotation of the rotating shaft 503 also drives the reciprocating coil... Rotating rod 708 causes the reciprocating screw 708 to move the screw nut 709 back and forth. The screw nut 709 then drives the connecting rod 710, causing the pulling piece 711 to slide back and forth within the limiting sleeve 712. The pulling piece 711 then drives the hinge 713, causing the slider 703 to slide back and forth on the annular slide rail 704. At this time, the slider 703 drives the annular tube 701 to continuously rotate in small forward and reverse directions, causing the nozzle 702 to vibrate, thus facilitating uniform spraying and preventing spray dead zones. By opening the air inlet valve 706 and connecting the pipeline, high-temperature and high-humidity gas or salt spray water vapor can be delivered into the test chamber 1, thereby facilitating the testing of damp heat aging and salt spray corrosion.

[0028] Example 3, see Figures 1-10 The cleaning component 8 includes a first hydraulic chamber 801, which is fixedly connected to the back of the shaft bracket 403. A first hydraulic rod 802 is slidably connected to the inner surface of the first hydraulic chamber 801. A second hydraulic chamber 803 is provided on the outer surface of the chamber door 307. The second hydraulic chamber 803 is connected to the first hydraulic chamber 801 by pipelines and is connected and communicated with the first hydraulic chamber 801 by a hose. Both the second hydraulic chamber 803 and the first hydraulic chamber 801 are filled with hydraulic oil. The volume of the second hydraulic chamber 803 is the same as that of the first hydraulic chamber 801. A second hydraulic rod 804 is slidably connected to the inner surface of the second hydraulic chamber 803. The second hydraulic rod 804 is topped with... A cleaning brush 805 is fixedly connected to the part. The cleaning brush 805 is arc-shaped and fits against the observation window 308. There are two sets of cleaning components 8. The second hydraulic chamber 803 in the two sets of cleaning components 8 is fixedly connected to the front and back of the door 307 respectively. The second hydraulic chamber 803 located on the back of the door 307 is connected to the first hydraulic chamber 801 located below through a hose. The hose passes through the door 307 and is fixedly connected. The cleaning brush 805 in the two sets of cleaning components 8 is slidably connected to the front and back of the observation window 308 respectively. The right end of the first hydraulic rod 802 in the two sets of cleaning components 8 is fixedly connected to a connecting plate 9. The connecting plate 9 is fixedly connected to the bottom of the screw nut 709.

[0029] When the aforementioned equipment is in use, as the lead screw nut 709 moves back and forth, it also drives the connecting plate 9 to move back and forth. The connecting plate 9 drives the first hydraulic rod 802 to slide back and forth within the first hydraulic chamber 801. At this time, the first hydraulic rod 802 continuously pushes the hydraulic oil in the first hydraulic chamber 801 into the second hydraulic chamber 803 or draws the hydraulic oil in the second hydraulic chamber 803 into the first hydraulic chamber 801. This causes the hydraulic oil to drive the second hydraulic rod 804 to repeatedly extend and retract within the second hydraulic chamber 803. At this time, the second hydraulic rod 804 drives the cleaning brush 805 to continuously rise and fall. The cleaning brush 805 slides up and down on both sides of the observation window 308 to wipe away the mist or water droplets, thus making it easier for the tester to observe the situation inside the test chamber 1 through the observation window 308 on the chamber door 307.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
