Description

Technical Field

[0001] The present invention relates to the field of thermomechanical testing of petroleum resins, and particularly to a thermomechanical analyzer for the production of modified petroleum resins. Background Art

[0002] Petroleum resins are a class of synthetic resins obtained by polymerizing aromatic and olefinic compounds generated during the petroleum refining process, usually in solid or granular form. Petroleum resins are widely used in many industrial fields, such as coatings, adhesives, rubber processing, inks, road markings, etc. This is because of their good adhesion, weather resistance, and adjustable softening point, making them irreplaceable in these industries. Thermomechanical analysis (TMA) is a commonly used technical means for testing the deformation characteristics of materials under the action of temperature, force, or stress. By testing the thermomechanical properties of modified petroleum resins, important bases can be provided for their further optimization and application.

[0003] Existing thermomechanical analyzers for the production of modified petroleum resins can usually perform performance tests such as thermal expansion and thermal contraction of materials, but most devices have the following deficiencies: one is that the test angle is relatively single and cannot comprehensively evaluate the performance of materials from multiple angles; the other is that the angle switching during the test process is relatively limited and cannot achieve comprehensive detection of samples at multiple three-dimensional angles. Therefore, existing devices cannot meet the requirements of high-precision and high-demand thermomechanical performance tests, especially in terms of multi-angle and all-round testing of materials, there are certain technical limitations.

[0004] To solve this problem, there is an urgent need for a thermomechanical analyzer that can perform multi-angle and all-round thermomechanical performance tests on petroleum resin samples and has a three-dimensional angle switching function. Such a device can comprehensively evaluate the deformation characteristics of modified petroleum resins under different temperature and stress conditions, and provide more accurate performance data for the production and application of modified petroleum resins.

Detailed implementation manners

[0041] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0042] As shown in combination with the accompanying drawings according to an embodiment of the present invention, as Figures 1 to 13 shown, the embodiment of the present invention provides a thermomechanical analyzer for the production of modified petroleum resin, including: an analysis base 1 and a functional cylinder 2 fixed above the analysis base 1. A refrigeration component 3 is arranged in the functional cylinder 2, and a heating component 4 is arranged above the functional cylinder 2. It further includes:

[0043] The closure member 5 is fixed on the functional cylinder 2 and is used to form a sealed furnace body with an adjustable angle. The closure member 5 includes: a furnace body frame 501 fixed above the functional cylinder 2; an angle bending plate 502 slidably arranged within the furnace body frame 501; a closure cover 503 fixed above the furnace body frame 501. The closure member 5 further includes: a corner rotator 504 fixed below on the functional cylinder 2; an electric telescopic rod 505 with its non-telescopic end fixed on the corner rotator 504; a curved rod 506 with one end fixed on the telescopic end of the electric telescopic rod 505 and the other end fixed on the closure cover 503.

[0044] The angle adjusting member 6 is rotatably arranged within the functional cylinder 2 and is used to adjust the angular position of the angle bending plate 502. The angle adjusting member 6 includes: a sliding seat curved plate 601 slidably arranged within the functional cylinder 2.

[0045] The detecting member 7 is fixed above the sliding seat curved plate 601 and is used to detect the thermo-mechanical properties of the resin and cooperate with the angle adjusting member 6 for three-dimensional detection. The detecting member 7 includes: a detecting support plate 701 fixed below above the sliding seat curved plate 601; a side detecting cylinder 702 fixed on the detecting support plate 701; a side abutting cylinder 703 slidably inserted within the side detecting cylinder 702; a fiber Bragg grating sensor 704 fixedly embedded within the side abutting cylinder 703; a first thermocouple 705 fixedly embedded within the side abutting cylinder 703; a linear displacement sensor 706 fixed on the end of the side detecting cylinder 702 far from the first thermocouple 705; a hydraulic sensor 707 fixed on the side detecting cylinder 702.

[0046] Specifically, the angle bending plate 502 and the furnace body frame 501 are made of heat-insulating and heat-preserving materials, and the thickness of the angle bending plate 502 is adjusted according to the actual situation. The sliding seat curved plate 601 is located between the upper part of the functional cylinder 2 and the outside of the placing table 802. In this embodiment, four sliding seat curved plates 601 are adopted. The number of sliding seat curved plates 601 that can be set is increased, and the corresponding number of angle bending plates 502 increases accordingly, and the clamping plates below the furnace body frame 501 increase accordingly. While the number of sliding seat curved plates 601 increases, the rotation angle of the sliding seat curved plate 601 is limited by the clamping plates of the furnace body frame 501.

[0047] By starting the angle - adjusting motor 606, the present invention can precisely adjust the measurement angle of the petroleum resin sample. The angle - adjusting motor 606 drives the angle - adjusting gear 608 to rotate along the angle - adjusting tooth ring 607, thereby driving the sliding - seat curved plate 601 to rotate, and further driving the detection support plate 701 to rotate. The detection support plate 701 further pushes the side - detection cylinder 702 to displace, and the displacement of the side - detection cylinder 702 will drive the angle - curved plate 502 to rotate within the furnace body frame 501. It realizes the precise measurement of the petroleum resin sample at different angles, enabling the sample to conduct thermomechanical property tests from multiple angles and comprehensively, ensuring the comprehensiveness and accuracy of the data. This three - dimensional angle switching can effectively evaluate the thermomechanical behaviors such as expansion and contraction of the petroleum resin sample under extreme temperature conditions, thus providing more detailed and reliable data support for the performance analysis of the resin.

[0058] The detection member 7 further includes: a top detection cylinder 7020, fixed to the closing cover 503; a top abutment cylinder 7021, slidably inserted into the top detection cylinder 7020; a top liquid pipe 7022, fixed to the top detection cylinder 7020; a restraint disc 7023, fixed to the curved rod 506.

[0059] The detection member 7 further includes: a hydraulic box 7024, fixed inside the function cylinder 2; a main liquid pipe 7025, fixedly inserted into the hydraulic box 7024; a liquid distribution pipe 7026, with one end fixed to the main liquid pipe 7025 and the other end penetrating out of the function cylinder 2; a liquid pump 7027, with the pump base fixed inside the function cylinder 2 and the working area fixed to the liquid distribution pipe 7026; a solenoid valve 7028, fixed to the liquid distribution pipe 7026; a hose 7029, with one end fixed to the solenoid valve 7028 and the other end fixed to the side liquid pipe 7019 and the top liquid pipe 7022.

[0060] Specifically, the internal auxiliary structures of the top detection cylinder 7020, the top abutment cylinder 7021 and the top liquid pipe 7022 are the same as those of the side detection cylinder 702, the side abutment cylinder 703 and the side liquid pipe 7019. The liquid entering the side detection cylinder 702 and the top detection cylinder 7020 maintains a certain heat insulation distance from the outside of the angle curved plate 502 to avoid the phenomenon of liquid expansion after heating.

[0061] Working principle: Place the petroleum resin sample on the second thermocouple 805. The camera 10 takes a top-down photo of the petroleum resin sample and analyzes the picture to determine whether the shape of the petroleum resin sample is regular (regular shapes such as cylindrical or rectangular petroleum resin samples), so as to judge whether angle adjustment is required during the detection of the petroleum resin sample. Measure data values from multiple angles for analysis; multiple measurement angles can be roughly planned through the picture, measurements are carried out, and the specific angle positions for temperature measurement are planned.

[0062] Start the liquid pump 7027. The liquid pump 7027 extracts the liquid in the hydraulic cartridge 7024 through the main liquid pipe 7025 and supplies it to the distribution pipe 7026. Open the corresponding solenoid valve 7028. The liquid enters the hose 7029. The liquid enters the side probe tube 702 from the hose 7029. The side piston 7010 is pushed to move by the liquid. The movement of the side piston 7010 drives the sliding sleeve 709 and the side abutment tube 703 to extend out of the side probe tube 702 until the first thermocouple 705 and the linear displacement sensor 706 of the side abutment tube 703 are attached to the outer surface of the petroleum resin sample; the liquid continuously enters the side probe tube 702. The first thermocouple 705 and the linear displacement sensor 706 start to apply a force to the outer surface of the petroleum resin sample. The reverse force of the first thermocouple 705 and the linear displacement sensor 706 is applied to the liquid in the side probe tube 702. The hydraulic sensor 707 detects that the liquid pressure in the side probe tube 702 starts to increase. This hydraulic value increases to a preset hydraulic value, and the length data of the side abutment tube 703 extending out of the side probe tube 702 is judged through the liquid injection volume. The initial temperature detected by the first thermocouple 705 and the initial deformation degree collected by the linear displacement sensor 706 are measured. The initial data collected at multiple measurement angles planned in sequence are measured, and the position that needs to be measured initially is restored. Then, the solenoid valve 7028 is closed.

[0063] The top probe tube 7020 and the top abutment tube 7021 are applied to the top of the petroleum resin sample, which plays a role in fixing and clamping the sample while measuring its thermal expansion, facilitating the fixation of the side probe tube 702 when switching the measurement angle position.

[0064] Start the heating element 4, the heating tube 402 heats the sealed area, start the circulation pump 807, and the circulation pump 807 circulates the air flow inside the sealed area through the circulation pipe 806 to make the internal temperature relatively uniform, heating the petroleum resin sample evenly. Uniform heating helps to ensure that the petroleum resin sample is under stable heating conditions throughout the test process, reduce the interference of external temperature changes, and improve the reliability and accuracy of the data; through the precise heating of the petroleum resin sample by the heating element 4, the comparison of the initial data and the data after heating can make the expansion performance of the sample change within a controllable and gradually changing temperature range; such temperature control heating helps to record parameters such as the expansion coefficient and deformation degree of the resin material at different temperatures, and improve the accuracy of the thermal expansion performance test.

[0065] During the heating process, the angle position of the petroleum resin sample can be continuously switched for detection, or the angle can be fixed by the four side abutting cylinders 703 for detection.

[0066] For the expansion of the petroleum resin sample after heating, the first thermocouple 705 detects the temperature, and the linear displacement sensor 706 detects the deformation. The expansion of the petroleum resin sample pushes the displacement of the first thermocouple 705, the linear displacement sensor 706, the movable plate 7013 and the displacement rod 7017, compresses the movable spring 7016, and the data is recorded by the linear displacement sensor 706. The acting force of the compression of the movable spring 7016 is applied to the indirect plate 7014, the side abutting cylinder 703, the sliding sleeve 709 and the side piston 7010, and the hydraulic pressure in the side exploration cylinder 702 is squeezed, and then the pressure value is detected by the hydraulic sensor 707.

[0067] Start the refrigeration compressor 301, and perform low-temperature measurement on the closed area through the replacement pipe 302. The heat generated by the refrigeration compressor 301 dissipates from the gap between the upper part of the functional cylinder 2 and the outside of the placement table 802.

[0068] Start the rotation angle motor 602, the rotation of the rotation angle motor 602 drives the rotation of the sample base 803, the rotation of the sample base 803 drives the lifting plate 804, the second thermocouple 805 and the petroleum resin sample to adjust the angle, and then the top exploration cylinder 7020 and the top abutting cylinder 7021 apply to the top of the petroleum resin sample for fixation.

[0069] Start the angle adjustment motor 606, the rotation of the angle adjustment motor 606 drives the rotation of the angle adjustment gear 608, the rotation of the angle adjustment gear 608 rotates along the angle adjustment tooth ring 607, the movement of the angle adjustment gear 608 drives the rotation of the sliding seat curved plate 601, the rotation of the sliding seat curved plate 601 drives the rotation of the detection support plate 701, the rotation of the detection support plate 701 drives the displacement of the side exploration cylinder 702, and the displacement of the side exploration cylinder 702 drives the displacement of the angle curved plate 502 in the furnace body frame 501, so as to switch the angle position of the side exploration cylinder 702 on the petroleum resin sample, facilitating the three-dimensional measurement of the petroleum resin sample.

[0070] By manually twisting the twisting cap 6017, the rotation of the twisting cap 6017 drives the rotation of the twisting rod 6016. The rotation of the twisting rod 6016 drives the rotation of the bevel gear pair 6018. The rotation of the bevel gear pair 6018 drives the rotation of the threaded rod 6015. The threaded rod 6015 screws into or out of the sample base 803, thereby adjusting the change in the height position of the lifting plate 804. The limit guide rod 6014 is used to assist in the lifting of the lifting plate 804, so as to adjust the height for placing the petroleum resin sample.

[0071] The telescopic movement of the electric telescopic rod 505 drives the curved rod 506, and then the curved rod 506 drives the change in the height position of the sealing cover 503, thereby opening or closing the enclosed area. The angulator 504 drives the electric telescopic rod 505, the curved rod 506 and the sealing cover 503 to rotate and move away from directly above the furnace body frame 501.

[0072] After the detection, the analysis data report is presented on the touch screen 102. The report can be saved through the data interface 104, or the data report can be uploaded online.
