Description

Technical Field

[0001] The present invention relates to the technical field of sealing material testing, and in particular to a sealing material performance testing device. Background Art

[0002] Sealing materials include sealants, gaskets, soft fillers and molded fillers, etc., which are used for sealing products. Some properties of sealing materials include elongation at break, tensile strength and tear strength.

[0003] Sealant used for vehicle body exterior seals is particularly susceptible to aging and wear and tear due to its harsh working environment, which is subject to various weather conditions such as humidity, rain, temperature differences between morning and evening, seasonal climate changes, sunlight, and thermal oxidative aging. Current sealants often develop surface cracking, deep cracking, hardening, brittleness, and peeling before they have been used for a sufficient period of time, leading to sealing failure. After sealing failure, the vehicle's sheet metal is prone to rust and yellowing, rotting, and sores. Even slight scratches can easily damage the surface or even cause it to fall off, shortening its service life.

[0004] Since sealants need to adapt to a variety of different environments in actual use to meet market demand, in the existing technology, the testing of sealants is carried out through different equipment, and each equipment can only test one performance of the sealant, which is time-consuming and costly, and is not conducive to the testing and development of sealants.

[0054] For the rotation described below, the viewing direction is from front to back, from top to bottom, and from right to left. When in use, the sealing material performance test device is first placed on a stable ground as required. First, the operator connects the first valve 211 on the left to a refrigerator through a telescopic hose, connects the first valve 211 on the right to a humidifier through a telescopic hose, connects the third circular tube 221 to a drain pipe, and connects the two heaters 206 to a control power supply. An appropriate amount of water is added to the sponge 303, and then the sealant is placed under normal temperature and humidity for 24 hours. The sealant is then squeezed into the mold for film injection. After the film injection is completed, the sealant is placed under normal temperature and humidity for 24 hours and then demolded. After demolding, it is continued to be placed under normal temperature and humidity for one week. It is then cut into twelve sealing strips, with two sealing strips in each group, for a total of six groups. Each group of sealing strips is placed in different environments for a period of time, and the sealing strips are tested to obtain data on elongation at break, tensile strength and tear strength, which are the performance of the sealing strips.

[0055] When the preparation work is completed, the operator takes a set of sealing strips and performs a performance test on them in a normal temperature and humidity environment;

[0056] Testing steps for elongation at break and tensile strength: The operator takes out two sealing strips, first places one end of the sealing strip on the first clamp 313 and clamps it, then places the other end of the sealing strip on the second clamp 314 and clamps it. Then, the operator controls the tensile testing machine 312 to start the test, and obtains the elongation at break and tensile strength data of the sealing strip under standard environmental conditions.

[0057] Tear strength test steps: The operator places another sealing strip in the strip groove 301a of the placement plate 301, controls the two third electric push rods 307 to retract, drives the mounting block 308, the limit plate 309, the cutter 310 and the adjusting bolt 311 to move downward together, allows the cutter 310 to contact the sponge 303 below, wets the cutter 310, and then controls the two third electric push rods 307 to push out, drives the connected components to reset together, controls the second electric slide 305 to move to the left on the outer surface of the second electric slide rail 304, and the two second electric slides 305 drive the third fixing plate 306, the third electric push rod 307, the mounting block 308, the limit plate 309, the cutter 310 and the adjusting bolt 311 to move to the left together, and waits until the cutter 310 moves to the two tapered grooves 301 b, the two second electric sliders 305 are controlled to stop moving, and then the two third electric push rods 307 are contracted, driving the connected parts to move together, and the sealing strip in the strip groove 301a is cut by the cutter 310. After cutting a right-angled cut, the cut sealing strip 2 is obtained, as shown in the figure, and then the two third electric push rods 307 are controlled to be pushed out, driving the connected parts to reset together, and the two second electric sliders 305 are controlled to drive the connected parts to reset together. Then the operator takes out the cut sealing strip 2, first places one end of it on the first clamp 313 to clamp it, and then places the other end of it on the second clamp 314 to clamp it, and then controls the tensile testing machine 312 to start testing to obtain the tear strength data of the sealing strip under standard environmental conditions.

[0058] Simulation of constant humidity and high temperature environment:

[0059] The operator places a set of sealing strips in the placement barrel 214. Since the simulated heat-resistant environment is too high and easily affects the surrounding environment, the two simulation systems are operated synchronously. Taking the simulation system on the left as an example, the first electric slider 203 is controlled to move to the right on the outer surface of the first electric slide rail 202. The two first electric sliders 203 drive the shell 204, the isolation layer 205, the heater 206, the first fixed plate 207, the spring telescopic column 208, the partition 209, the first round tube 210, the first valve 211 and the like to move together. The two first electric sliders 203 are controlled to stop moving, and the simulation system on the right also operates in the same way as the simulation system on the left, driving the connected components to move to the left together. After the two simulation systems stop, the two insertion strips 212 are inserted into one of the two first electric sliders 203. In each groove 204a, two partitions 209 are inserted into a rectangular hole 223a respectively and merged together to seal the mounting tube 223, so that a sealed space is formed inside the two shells 204. Then the two heaters 206 are controlled to start heating, so that the temperature inside the two shells 204 rises. By merging the two shells 204, the internal space of the two shells 204 is sealed to prevent heat leakage in the space. The heat in the two shells 204 is then insulated by the two isolation layers 205 to avoid the problem of heat dissipation too quickly, which affects the surrounding environment. After the temperature sensor 213 detects that the temperature inside the two shells 204 rises to 120 degrees, the two heaters 206 are controlled to stop heating continuously and maintain the temperature at 120 degrees. The two sealing strips are placed at a high temperature of 120 degrees for three hours. After three hours, the two heaters 206 are controlled to turn off, and the two simulation systems are controlled to drive the connected components to reset together. Then the operator takes out the two sealing strips and places them under normal temperature and humidity conditions for four hours.

[0060] After the two sealing strips are placed under normal temperature and humidity conditions for four hours, the operator takes one sealing strip and works according to the test steps of elongation at break and tensile strength to obtain the elongation at break and tensile strength data of the sealing strip under heat-resistant environment conditions;

[0061] The operator then operates another sealing strip according to the tear strength test steps to obtain the tear strength data of the sealing strip under heat-resistant environment conditions.

[0062] Simulation of high humidity and high temperature environment:

[0063] The operator places a set of sealing strips in the placement barrel 214 and controls the two simulation systems to run synchronously. The two first electric sliders 203 on the left drive the connected components to move to the right together, and the two first electric sliders 203 on the right drive the connected components to move to the left together. By combining the two shells 204 and the two partitions 209, the internal space of the two shells 204 is sealed to prevent heat leakage in the space. The operator then opens the first valve 211 on the right to control the external humidifier to start, and deliver moisture to the interior of the two shells 204. At the same time, the two heaters 206 are controlled to start heating. The temperature inside the two shells 204 rises until the humidity inside the two shells 204 reaches 95%. After the temperature rises to 70 degrees, the external humidifier is controlled to deliver appropriate moisture, and the two heaters 206 maintain the temperature at 120 degrees. The two sealing strips are placed in an environment with a high temperature of 70 degrees and a humidity of 95% for 300 hours. After 300 hours, the external humidifier and the two heaters 206 are controlled to be closed, and the first valve 211 on the right is closed. The two simulation systems are controlled to reset the connected components. The operator then removes the two sealing strips and places them under normal temperature and humidity conditions for four hours.

[0064] After the two sealing strips are placed under normal temperature and humidity conditions for four hours, the operator takes one sealing strip and works according to the test steps of elongation at break and tensile strength to obtain the elongation at break and tensile strength data of the sealing strip under the conditions of humidity and heat resistance;

[0065] The operator then operates another sealing strip according to the tear strength test steps to obtain the tear strength data of the sealing strip under the conditions of humidity and heat resistance.

[0066] Simulation of an environment with normal temperature, humidity and light:

[0067] The operator places a set of sealing strips in the placement barrel 214. Since the simulated sunlight is achieved through radiation and the illumination time is long, and the operator is seriously affected by the radiation for a long time, it will seriously affect his health. Therefore, the four second electric push rods 225 are controlled to be pushed out, driving the second connecting plate 226 and the arc baffle 227 to move downward, and the two rectangular holes 223a are closed by the two arc baffles 227. The two simulation systems operate synchronously. Taking the simulation system on the left as an example, the two first electric sliders 203 are controlled to drive the connected components to move to the right together, and the partition 209 contacts the arc baffle 227 when moving, forcing the partition 209 to stop moving, and the two spring telescopic columns 208 are compressed. The simulation system on the right also operates in accordance with the working mode of the simulation system on the left, driving the connected components to move to the left together, forcing The other partition 209 no longer moves, so that the installation cylinder 223 is no longer enclosed by the two partitions 209, but the two shells 204 are still merged, and the internal space of the two shells 204 is also sealed. Then, the solar radiation simulator 222 is controlled to open, and the two sealing strips in the placement barrel 214 are irradiated to achieve the lighting effect. The radiation of the solar radiation simulator 222 is isolated by the two isolation layers 205 to prevent the sealing strips from being affected by the radiation emitted by the solar radiation simulator 222 during the lighting period. After 750 hours of lighting, the solar radiation simulator 222 is controlled to close, and the two first electric sliders 203 drive the connected components to reset. After the four second electric push rods 225 drive the connected components to reset, the operator removes the two sealing strips and places them under normal temperature and humidity conditions for four hours.

[0068] After the two sealing strips are placed under normal temperature and humidity conditions for four hours, the operator takes one sealing strip and works according to the test steps of elongation at break and tensile strength to obtain the elongation at break and tensile strength data of the sealing strip under light aging environment;

[0069] The operator then operates another sealing strip according to the tear strength test steps to obtain the tear strength data of the sealing strip under the light aging environment.

[0070] Environment with normal temperature and humidity, and soaked in water at a certain temperature:

[0071] The operator places a set of sealing strips in the placement bucket 214. Since the sealing strips are placed in water, they will float on the water surface due to the buoyancy of the water, resulting in the sealing strips not being completely immersed in the water, making the test data inaccurate. Therefore, the operator controls the two first electric push rods 217 to push out, driving the first connecting plate 218 and bracket 219 on the left to move to the right, and the first connecting plate 218 and bracket 219 on the right to move to the left. After the two brackets 219 move to the top of the two sealing strips, the operator pours 40-degree distilled water into the placement bucket 214. The two sealing strips are subjected to the buoyancy of the water. , slowly rising with the increase of water. After the two sealing strips come into contact with the two brackets 219, they are restricted by the two brackets 219, so that the two sealing strips are immersed in distilled water, preventing the two sealing strips from floating on the water surface, thereby avoiding the problem of inaccurate test data in the future. After the two sealing strips are immersed for 72 hours, the second valve 220 is controlled to open to drain the distilled water in the placement barrel 214, and then the two first electric push rods 217 are controlled to retract, driving the connected components to reset. The operator removes the two sealing strips and places them under normal temperature and humidity conditions for 24 hours;

[0072] After the two sealing strips are placed under normal temperature and humidity conditions for 24 hours, the operator takes one sealing strip and performs the test according to the test steps of elongation at break and tensile strength to obtain the elongation at break and tensile strength data of the sealing strip under water-resistant environment;

[0073] The operator then operates another sealing strip according to the tear strength test steps to obtain the tear strength data of the sealing strip in a water-resistant environment.

[0074] Normal humidity and low temperature environment simulation:

[0075] The operator places a set of sealing strips in the placement barrel 214 and controls the two simulation systems to run synchronously. The two first electric sliders 203 on the left drive the connected components to move to the right together, and the two first electric sliders 203 on the right drive the connected components to move to the left together, so that the two shells 204 form a sealed cabin to achieve a sealing effect. The operator then opens the first valve 211 on the left and controls the external refrigerator to start, supplying cold air to the inside of the two shells 204, causing the two shells 204 to start cooling. After the temperature sensor 213 detects that the temperature inside the two shells 204 drops to minus forty degrees, the refrigerator is controlled to shut down and no longer supply cold air. Then the first valve 211 on the left is closed, and the four first electric sliders 203 drive the connected components to reset. The operator observes whether there are cracks in the two sealing strips in the placement barrel 214 to obtain the cold resistance data of the sealing strips in a cold environment.
