Description

Technical Field

[0001] The utility model relates to the technical field of solid rocket engines, in particular to a rapid detection device for adhesives. Background Art

[0002] The adhesive material for the thermal insulation layer of solid rocket motors is a key material for solid rocket motors. It is composed of polymer materials with excellent bonding properties and process applicability. Currently, the bonding of the thermal insulation layer of solid rocket motors requires the adhesive material to be mixed on-site during assembly and promptly poured or painted onto the bonded area for room temperature curing. This is a non-pyrotechnic area and must meet the ExdⅡBT4 explosion-proof grade requirements. Rapid performance testing, pouring, or painting is required within the pot life of the adhesive material after mixing. Traditional sampling and testing methods are time-consuming and cannot quickly detect the performance status of the adhesive within its pot life, failing to meet the bonding process requirements for the thermal insulation layer during on-site assembly. Currently, there is a lack of effective testing methods and means to quickly detect the performance of the mixed glue before the insulation layer is bonded, poured or painted, and meet the requirements of no-pyrotechnic areas and ExdⅡBT4 explosion-proof level. If it is directly poured or painted on the bonded area without rapid testing, and its performance test is found to be unqualified after bonding and curing, since the process after the insulation layer is bonded is irreversible, it will leave serious hidden dangers to the bonding of the solid rocket engine insulation layer.

[0003] Therefore, it is necessary to provide a rapid detection device for adhesives to solve the above problems. Utility Model Content

[0040] like Figures 1 to 7As shown, this embodiment provides a rapid detection device for adhesives, which includes a heating microenvironment component 1 and a carrier 2. The heating microenvironment component 1 includes a heating microenvironment housing 11 and a heating core 12. The heating core 12 is located in the heating microenvironment housing 11. The heating core 12 has a heating space therein, which passes through one end of the heating core 12 and forms an insertion interface. The carrier 2 can be plugged into the heating space through the insertion interface. The carrier 2 is provided with a groove 221, and the adhesive can be placed in the groove 221. By filling the groove 221 in the carrier with the adhesive to be tested, and then plugging the carrier 2 into the heating space of the heating core 12 for heating and curing, the rapid curing of the adhesive to be tested is achieved, thereby achieving rapid testing of the relevant properties of the adhesive to be tested, so as to quickly determine whether the adhesive meets the bonding process requirements of the insulation layer during on-site assembly. At the same time, the rapid detection device of the adhesive has the characteristics of simple operation, good portability, good environmental adaptability, stable performance and high efficiency. The total use time does not exceed 10 minutes. In addition to meeting the use process operation requirements, it increases the applicable period of the infusion or brushing process of the solid rocket engine insulation layer adhesive material, effectively improving the stability, reliability and processability of the solid rocket engine insulation layer bonding.

[0041] Preferably, if Figure 2 As shown, the heating microenvironment assembly 1 further includes an insulation layer 13, which is disposed between the heating microenvironment housing 11 and the heating core 12. The heating core 12 occupies 1 / 2-1 / 3 of the entire space of the heating microenvironment assembly 1, with the remaining space being provided for the insulation layer 13. Exemplarily, the insulation layer 13 is provided as an asbestos layer to prevent excessively high temperatures from being transferred to the heating microenvironment housing 11 and damaging surrounding equipment. Of course, in other embodiments, the insulation layer 13 may be made of other materials as long as it provides thermal insulation.

[0042] Specifically, if Figure 6 and Figure 7 As shown, the carrier 2 includes a heat-conducting carrier 21 and an anti-sticking carrier 22. The anti-sticking carrier 22 is located on the heat-conducting carrier 21, and the anti-sticking carrier 22 is provided with the above-mentioned groove 221. The anti-sticking carrier 22 is chemically stable and has high-temperature resistance. It adds an anti-stick coating and does not chemically react with the adhesive. It can be used to solidify the glue to be tested and prevent the adhesive from sticking, which facilitates the demoulding of the adhesive sample and the cleaning of the residue; the heat-conducting carrier 21 has a heat-conducting function, which conducts heat to the adhesive in the anti-sticking carrier 22, thereby heating and curing the adhesive. Exemplarily, the material of the heat-conducting carrier 21 and the anti-sticking carrier 22 are both aluminum, and a polytetrafluoroethylene sintered layer is provided on the surface to improve its mechanical strength, hardness and wear resistance, and improve corrosion resistance and dimensional stability. Of course, in other embodiments, the heat-conducting carrier 21 and the anti-sticking carrier 22 can be other materials as long as they have the above-mentioned functions, which can be determined according to actual conditions.

[0043] Preferably, in this embodiment, a handle 211 is provided at one end of the heat conducting carrier 21 to facilitate placing the heat conducting carrier 21 into or taking it out of the heating microenvironment assembly 1 , thereby improving operability and saving operation time.

[0044] Optionally, the anti-stick carrier 22 may be provided with one, two, or multiple grooves 221. The specific size is determined based on the minimum size of the test sample obtained by curing the adhesive to be tested, the number of test samples, test efficiency, and heating space, and is not specifically limited here. For example, the groove 221 is preferably square, with dimensions of at least 20 mm * 20 mm * 4 mm, preferably a square sample of 20 mm * 20 mm * 4 mm.

[0045] Furthermore, the rapid adhesive detection device also includes a power supply 3 and a heating resistor 4. The power supply 3 is electrically connected to the heating resistor 4, and the power supply 3 supplies power to the heating resistor 4. The heating resistor 4 is connected to the heating core 12. The heating resistor 4 is a resistance element used to generate heat in a circuit. When the current generated by the power supply 3 passes through the heating resistor 4, the heat generated by the heating resistor 4 is transferred to the heating core 12, causing the heating core 12 to heat the carrier 2 in the heating space.

[0046] Preferably, the rapid detection device for adhesives also includes a power converter 8, which is connected to the power supply 3. The power supply 3 can convert the 220V voltage into a safe voltage of 24V through the power converter 8, that is, low-voltage direct current is used instead of conventional high-voltage (above 36V) alternating current, and the heating function is realized in the heating core 12, which is safe, reliable and meets the ExdIIBT4 explosion-proof requirements.

[0047] In this embodiment, the rapid adhesive detection device also includes a thermostat 5 and a relay. The thermostat 5 is connected to a power converter 8 and, via the relay, to a heating resistor 4. The relay is used to control the on / off switching of the thermostat and the heating resistor. The thermostat 5 is used to control the heating temperature of the heating resistor 4, thereby controlling the temperature of the heating space within the heating core 12, so that the heating space reaches the desired temperature. For example, the range of the thermostat 5 is 300°C, with a tolerance of 2°C.

[0048] Furthermore, the rapid adhesive detection device also includes a temperature sensor 6, which is connected to the heating core 12 and is used to detect the temperature of the heating space within the heating core 12. The temperature sensor 6 is electrically connected to the thermostat 5 and can transmit the detected temperature signal to the thermostat 5, so that the thermostat 5 can adjust the temperature of the heating space, ultimately achieving the desired temperature in the heating space and achieving effective energy saving. For example, a circular hole with a diameter of 1.3 cm is provided at the rear end of the heating core 12, through which the temperature sensor 6 and the heating resistor 4 are respectively connected to the heating core 12.

[0049] Optionally, the adhesive rapid detection device further includes a master control switch 9 , which is connected to the power converter 8 and the temperature controller 5 respectively, and is used to control the on and off of the power converter 8 and the temperature controller 5 .

[0050] Furthermore, the rapid detection device for adhesives also includes an explosion-proof cover 7, and the heating microenvironment component 1 is located inside the explosion-proof cover 7. An avoidance port is provided on the explosion-proof cover 7, and the avoidance port is arranged opposite to the plug interface, so that the carrier 2 can be placed in or taken out of the heating microenvironment component 1 through the avoidance port and the plug interface, thereby facilitating the placement or removal of the adhesive, improving the operability of the device, and saving operation time.

[0051] Preferably, the material of the explosion-proof housing 7 includes one of metal, composite, and ceramic materials. In this embodiment, the material of the explosion-proof housing 7 is set to be metal, which specifically meets the requirements of ExdⅡBT4 explosion-proof grade and is safer. Of course, in other embodiments, the material of the explosion-proof housing 7 can be selected from composite materials and ceramic materials as long as they meet the requirements of ExdⅡBT4 explosion-proof grade, and the specific material is determined according to actual conditions.

[0052] The following is a method for using the rapid detection device for the adhesive: first, add the mixed adhesive to be tested into the groove 221 of the preheated anti-sticking carrier 22, and add the liquid until the liquid level is full and protruding. After completion, insert the carrier 2 horizontally into the heating space, heat it in time, take out the carrier 2 after heating for a period of time, remove the anti-sticking carrier 22 and put it into room temperature water for rapid cooling, take out the solidified adhesive in the anti-sticking carrier 22 after cooling for a period of time, obtain the sample to be tested, wipe off the surface moisture, observe the state of the sample to be tested and wait for room temperature cooling, and use a hardness tester to test its hardness after cooling for a period of time. If there are any of the following conditions in the sample to be tested, such as divergent bubbles, overall foaming, insufficient curing, sticky surface, unformed sample or hardness value lower than the requirement, the test is unqualified; if the sample meets all the conditions such as no divergent bubbles, smooth surface, and hardness value higher than the required value, the test is qualified, proving that the performance of the solid rocket engine insulation layer adhesive material is qualified after mixing and can be poured into or brushed on the area to be bonded.
