Description

Technical Field

[0001] The invention relates to the technical field of material performance testing equipment, and specifically proposes a comprehensive testing platform for physical properties of aerogel composite materials. Background Art

[0002] Aerogel composites are advanced composite materials that combine the unique properties of aerogels with the properties of other materials. Aerogel itself is a porous solid material prepared by the sol-gel process, with extremely low density, high specific surface area, excellent thermal insulation and good optical transparency. When aerogel is combined with other materials such as fibers, polymers, metals or ceramics, composite materials with unique physical and chemical properties can be created, which are suitable for a variety of special applications.

[0003] Aerogel insulation pads are pad-shaped products made of aerogel as the main material and combined with fiber fabrics, plastic polymers, inorganic fillers or foams. They show excellent thermal insulation performance and are widely used in various occasions and fields that require efficient thermal insulation, light weight and space saving. The specific performance of aerogel insulation pads made of different materials will vary. In addition, in some special applications, aerogel insulation pads, in addition to excellent thermal insulation performance, must also have additional properties such as low water absorption, waterproofness and water pressure resistance. In the actual production process, in order to verify the comprehensive physical properties of the aerogel insulation pads produced and confirm whether they meet the standards, it is necessary to conduct multiple performance tests on the aerogel insulation pads, such as water absorption, waterproofness, water pressure resistance, flame retardancy and thermal insulation.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] like Figure 1 , Figure 2 and Figure 3As shown, a comprehensive testing platform for the physical properties of aerogel composite materials. In the present invention, the aerogel composite material specifically refers to an aerogel thermal insulation pad, hereinafter referred to as a thermal insulation pad. The comprehensive testing platform provided by the present invention can perform comprehensive testing on the thermal insulation pad's water absorption, waterproofness, water pressure resistance, and multiple physical properties of flame retardancy and thermal insulation; the platform includes a testing frame 1, the testing frame 1 includes two horizontally arranged and vertically distributed end plates 11, a back plate 12 is welded between the two end plates 11, the testing frame 1 can be fixed to a specially arranged support frame through the back plate 12 to achieve fixed support and installation of the platform, and four guide columns 13 are vertically fixed between the two end plates 11 by bolts.

[0034] like Figure 1 and Figure 2 As shown, a separation component 2 is assembled on the detection frame 1, and the separation component 2 includes a separation cylinder 21 vertically fixed to the top of the upper end plate 11 by bolts, and a sliding cylinder seat 22 vertically slidably mounted on four guide pillars 13, and the sliding cylinder seat 22 is fixed to the output end of the separation cylinder 21 by bolts; a lockable cylinder seat 4 is arranged below the sliding cylinder seat 22, and the lockable cylinder seat 4 is vertically slidably mounted on the four guide pillars 13, and two locking components 41 that cooperate with the detection frame 1 are horizontally arranged on the lockable cylinder seat 4, and the locking component 41 includes a pin sleeve 411 welded on the lockable cylinder seat 4, a pin 412 that passes through and slides on the pin sleeve 411, and a socket 413 that cooperates with the pin 412, and the socket 413 is provided with a socket for the pin 412 to be inserted. The socket 413 in one locking assembly 41 is horizontally fitted and fixed on two of the guide pillars 13, and the socket 413 in the other locking assembly 41 is horizontally fitted and fixed on the other two guide pillars 13; obviously, when the two pins 412 are inserted into the sockets of the socket 413, the lockable cylinder seat 4 is relatively fixed on the four guide pillars 13, and when the two pins 412 are pulled out, the lockable cylinder seat 4 naturally slides down along the guide pillars 13 under the action of gravity.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the bottom end of the sliding cylinder seat 22 is fixed with a No. 1 cylinder 3 by screws, and a No. 2 cylinder 5 is fixed on the lockable cylinder seat 4. The No. 1 cylinder 3 and the No. 2 cylinder 5 are arranged vertically coaxially opposite to each other; a pressure ring 31 is integrally formed on the inner wall of the No. 1 cylinder 3; a step cylinder 52 for inserting the No. 1 cylinder 3 is arranged on the No. 2 cylinder 5, and the No. 2 cylinder 5 is installed on the lockable cylinder seat 4 through, and the lower end surface of the step cylinder 52 overlaps the lockable cylinder seat 4 and is locked and fixed by screws; a circular ring-shaped insert is coaxially opened on the inner step surface of the step cylinder 52 Connecting groove 521; driven by the separation cylinder 21, the sliding cylinder seat 22 can drive the No. 1 cylinder 3 to move vertically relative to the No. 2 cylinder 5. When the sliding cylinder seat 22 drives the No. 1 cylinder 3 to move downward, the port of the No. 1 cylinder 3 can be inserted into the step cylinder 52, and the outer wall of the No. 1 cylinder 3 slides tightly against the inner wall of the step cylinder 52. As the No. 1 cylinder 3 drops to the lowest position, the port of the No. 1 cylinder 3 is plugged into the plug-in groove 521. At this time, the plug-in fitting between the No. 1 cylinder 3 and the No. 2 cylinder 5 is in a relatively sealed state.

[0036] The aerogel insulation pad used for testing can be randomly intercepted from the aerogel insulation pad products produced, and needs to be pre-cut into round materials. The round insulation pad can be placed in the No. 1 cylinder 3 in terms of size, and can also be placed on the inner step surface of the step cylinder 52. In the actual testing process, when the No. 1 cylinder 3 is inserted into the step cylinder 52, the aerogel composite material in the testing state is positioned and placed between the pressure ring 31 and the step surface of the step cylinder 52. In addition, it should be noted that in order to facilitate the observation of the testing state of the insulation pad, in the present invention, the No. 1 cylinder 3 and the No. 2 cylinder 5 are both made of transparent colorless glass materials.

[0037] like Figure 2 and Figure 5 As shown, a detection assembly No. 1 6 is arranged inside the cylinder No. 1 3, and a detection assembly No. 2 7 is mounted on the detection frame 1 below the cylinder No. 2 5; a circular guide cylinder 51 is coaxially arranged on the bottom end surface of the cylinder No. 2 5, and a circular hole is provided in the guide cylinder 51 on the bottom end surface of the cylinder No. 2 5, and the radius of the circular hole is smaller than the radius of the guide cylinder 51, that is, the lower end surface of the cylinder No. 2 5 remains in the guide cylinder 51; an inclined cone surface 53 is arranged in the cylinder No. 2 5 for guiding the liquid to flow from the surrounding to the circular hole.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the second detection assembly 7 includes a carry component 71, which includes a travel table 711 vertically slidably mounted on four guide pillars 13 and a driving screw 712 vertically rotatably mounted on the bottom of the travel table 711 through a bearing, and the driving screw 712 is threadedly mounted on the end plate 11 below, and a horizontally arranged slide groove is provided on the travel table 711, and a sliding seat 72 is slidably mounted in the slide groove on the travel table 711, and a water injection pipe 74 for detecting the water absorption rate of the aerogel composite material is fixed along the sliding direction, and the weight of the aerogel composite material is detected before and after the water absorption rate detection. The electronic scale 73 and the flame nozzle 75 for flame retardant detection are provided; it should be noted that the electronic scale 73, the water injection pipe 74 and the flame nozzle 75 only need to be fixed on the sliding seat 72 along the sliding direction, and there is no special requirement for the installation arrangement sequence. The electronic scale 73 is an existing electronic weighing device, the electronic scale 73 is disc-shaped, and the radius of the electronic scale 73 is slightly smaller than the inner diameter of the guide cylinder 51; the water injection pipe 74 is connected to the external water tank through a water pipe, and a control valve and a small two-way pump can be installed in the pipeline to inject and pump water. The flame nozzle 75 can be connected to the liquefied gas through the gas pipe, and the flame size and intensity of the flame nozzle 75 are adjustable.

[0039] On the one hand, the sliding seat 72 can be moved manually so that the electronic scale 73, the water injection pipe 74 and the flame nozzle 75 can be aligned with the guide cylinder 51. On the other hand, the travel platform 711 can be driven upward by manually rotating the driving screw 712, so that the electronic scale 73, the water injection pipe 74 or the flame nozzle 75 can be switched and plugged into the guide cylinder 51. In order to achieve plug-in positioning and to unify the detection standards, a sealing pressure plate 741 is fixed on the water injection pipe 74. When the water injection pipe 74 is aligned and plugged into the guide cylinder 51, the side wall of the sealing pressure plate 741 is tightly attached to the inner wall of the guide cylinder 51, the pipe head of the water injection pipe 74 passes through the circular hole, and the sealing pressure plate 741 is pressed against the bottom end surface of the No. 2 cylinder 5 located inside the cylinder. On the basis of forming the plug-in positioning, the sealing of the inner circular hole of the guide cylinder 51 is achieved. A plug-in plate 751 is welded on the flame nozzle 75, and a plurality of air holes 752 are provided on the plug-in plate 751; when the flame nozzle 75 is aligned and plugged into the guide tube 51, the side wall of the plug-in plate 751 is tightly attached to the inner wall of the guide tube 51, and the air holes 752 are connected to the circular hole, so that normal air circulation can be formed inside and outside the No. 2 cylinder 5. Here, it should be particularly noted that when weighing by the electronic scale 73, the lock of the lockable cylinder seat 4 is released, and the No. 2 cylinder 5 naturally falls on the electronic scale 73, so that weighing can be achieved. In addition, the lockable cylinder seat 4 remains locked, so that the water injection pipe 74 and the flame nozzle 75 are aligned with the guide tube 51 and inserted, and the sealing pressure plate 741 and the plug-in plate 751 can be pressed upward against the end surface inside the guide tube 51.

[0040] like Figure 1 , Figure 2 and Figure 6As shown, the first detection assembly 6 includes a spray plate 61 for performing a water pressure resistance test on the aerogel composite material and a temperature measuring plate 62 for performing a synchronous temperature detection when performing a flame retardant test on the aerogel composite material. The temperature measuring plate 62 is mounted on the spray plate 61; a pipe joint 611 is provided at one end of the spray plate 61, and the pipe joint 611 is fixed on the first cylinder 3 through the pipe. The pipe joint 611 can be connected to an external water supply device through a water pipe, and the water supply device is installed with an existing booster pump for adjusting the water pressure; the spray plate 6 A plurality of nozzles 612 are arranged at the other end, and the plurality of nozzles 612 are evenly distributed in the circumferential direction about the center of the spray plate 61; a plurality of sleeves 621 are arranged on the temperature measuring plate 62, which are slidably matched with the plurality of nozzles 612 in a one-to-one correspondence, and the nozzles 612 are exposed in the sleeves 621; a push cylinder 622 is fixed at the top of the No. 1 cylinder 3, and the temperature measuring plate 62 is fixed at the output end of the push cylinder 622. The temperature measuring plate 62 is an existing disc-shaped resistance temperature detector, and a temperature sensitive resistor is embedded in the temperature measuring plate 62 for real-time detection of feedback temperature.

[0041] The present invention provides a comprehensive testing platform for the physical properties of aerogel composite materials, which can perform comprehensive tests on the water absorption rate, waterproofness, water pressure resistance, and flame retardancy and heat insulation of aerogel thermal insulation pads; each performance test is described separately below: Water absorption test: First, place the circular thermal insulation pad material to be tested on the inner step surface of the step cylinder 52, then move the electronic scale 73 to a position aligned with the guide cylinder 51, and release the lockable cylinder seat 4, so that the second cylinder 5 together with the thermal insulation pad falls on the electronic scale 73 to measure the initial weight. It should be added that the overall weight of the second cylinder 5 is known.

[0042] After the initial weight measurement is completed, the lockable cylinder seat 4 is moved upward and re-locked, and then the No. 1 cylinder 3 is inserted into the step cylinder 52 through the separation component 2, but the No. 1 cylinder 3 is kept at a height position where it is not inserted into the insertion groove 521; then, the water injection pipe 74 is aligned and inserted into the cylinder, and water is immediately injected into the No. 2 cylinder 5, so that the water flows to the top of the insulation pad until the insulation pad is completely immersed in the water layer and the water injection stops; after the predetermined immersion and water absorption time is reached, the water in the No. 2 cylinder 5 is completely pumped out through the water injection pipe 74, and then the No. 1 cylinder 5 is Cylinder No. 3 is moved upward and left to stand for a while, and turned over when there is basically no water dripping on one side of the thermal insulation pad (handle it gently when turning it over, and do not squeeze the thermal insulation pad). It is left to stand for a while again, and when there is basically no water dripping on the other side of the thermal insulation pad, and the inside of cylinder No. 2 5 is basically dry, cylinder No. 2 5 and the thermal insulation pad are weighed as a whole again by electronic scale 73; finally, the water absorption rate of the thermal insulation pad is calculated and analyzed based on the weights obtained by weighing before and after, and it is checked whether the water absorption rate of the aerogel thermal insulation pads produced in this batch meets the design requirements.

[0043] Conduct water pressure resistance (waterproofness) test: First, place the circular thermal insulation pad material to be tested on the inner step surface of the step cylinder 52, then drive the No. 1 cylinder 3 downward through the separation component 2, so that the No. 1 cylinder 3 is fully inserted into the insertion groove 521, and the pressure ring 31 squeezes and presses the edge of the thermal insulation pad onto the step surface of the step cylinder 52. The pressure ring 31 completes the compression and fixation of the thermal insulation pad while achieving sealing at the edge. Then, the upper end surface of the thermal insulation pad is sprayed with multiple nozzles 612 of the spray plate 61 to conduct water pressure resistance test, and the water pressure is gradually increased to simulate different water pressure environments faced by the thermal insulation pad. During the test process, Observe whether the thermal insulation pad has water seepage or even rupture, and record the water pressure value sprayed by the nozzle 612 when water seepage just occurs. You can also record the water pressure value when rupture occurs. The water pressure value obtained by the test reflects the water pressure resistance of this batch of aerogel thermal insulation pads. The higher the water pressure resistance value, the better the waterproof performance. Before the test, in order to facilitate the rapid observation of whether the thermal insulation pad has water seepage, before placing the thermal insulation pad, a moisture sensing test paper can be attached under the thermal insulation pad. For example, cobalt chloride test paper is used in conjunction with the test. The cobalt chloride test paper appears blue in a dry state. When the thermal insulation pad has water seepage, the test paper changes from blue to pink after absorbing water, thereby detecting whether there is water seepage at the first time.

[0044] Conduct a flame retardant heat insulation test: first, place the circular heat insulation pad material to be tested on the inner step surface of the step cylinder 52, and then, press and fix the heat insulation pad on the step surface of the step cylinder 52 by the pressure ring 31, so that the upper and lower spaces of the No. 1 cylinder 3 and the No. 2 cylinder 5 are separated by the heat insulation pad; then, drive the temperature measuring disk 62 down by the push cylinder 622, so that the temperature measuring disk 62 passes through the pressure ring 31 and fits in contact with the upper end surface of the heat insulation pad, and record the initial temperature; then, ignite the flame nozzle 75, and insert the flame nozzle 75 into the guide cylinder 51, adjust the flame size so that the flame burns directly below the heat insulation pad, and observe the insulation. Whether the heat pad will be ignited, whether it has a flame retardant effect, and the temperature above the insulation pad is monitored in real time through the temperature measuring disk 62. It can be foreseen that as the flame nozzle 75 continues to spray fire and releases a large amount of heat, it will inevitably cause the overall temperature of the internal space of the No. 1 cylinder 3 and the No. 2 cylinder 5 to rise rapidly. Through continuous real-time monitoring of the temperature measuring disk 62, a change curve corresponding to temperature and time can be obtained, and the time the temperature lasts before it rises significantly can be intuitively obtained through the curve graph. The longer the time at the selected temperature node, the better the insulation effect of the insulation pad, and it can be verified whether the design requirements are met.

[0045] The present invention provides a comprehensive testing platform for the physical properties of aerogel composite materials, which can perform comprehensive testing on the water absorption rate, waterproofness, water pressure resistance and flame retardancy and thermal insulation of aerogel thermal insulation pads; it has higher integration and comprehensiveness, replaces the existing testing method of independently testing multiple properties during testing, can perform rapid switching operations for multiple performance tests, and greatly improves the convenience and operability of the test; and the multiple performance tests are all performed in a relatively closed test environment, the test standards are relatively unified, and the influence of uncertain factors such as temperature, humidity, wind force, wind direction and the like in the surrounding environment on the test results is reduced, the test error is reduced, and the authenticity and accuracy of the test are improved.
