Description

Rubber preparation system Technical Field

[0001] This utility model relates to the field of rubber, and in particular to a rubber preparation system. Background Technology

[0002] Oil-extended rubber is a mixture of rubber and a large amount of softening filler oil. Oil extrusion improves the rubber's properties, such as increasing its resistance to wet skids and its plasticity, and making it easier to mix. A common oil extrusion process involves first preparing a polymer base solution, then mixing the filler oil with the base solution before coagulation, and finally allowing the solution to coagulate to obtain the oil-extended rubber. When extruding the base solution, the amount of filler oil added is related to the mass of dry rubber in the base solution. However, current methods for testing the mass content of dry rubber in the base solution have low accuracy, making it difficult to obtain timely information and guide subsequent operations, leading to problems such as ineffective control of the oil extrusion amount. Summary of the Invention

[0003] Based on this, some embodiments of this application provide a rubber preparation system that can improve the accuracy of testing the dry rubber content in rubber liquid, thereby improving the stability and oil filling qualification rate of subsequent oil filling.

[0004] A rubber preparation system, comprising:

[0005] A base adhesive supply device for supplying base adhesive;

[0006] A viscosity testing device is used to test the viscosity of the base adhesive supplied by the base adhesive supply device;

[0007] A control device, electrically connected to the viscosity detection device, is used to determine the dry adhesive content in the base adhesive solution based on the viscosity detected by the viscosity detection device and the correspondence between viscosity and dry adhesive mass percentage.

[0008] In some embodiments, the base adhesive supply device includes a rubber synthesis device and a monomer removal device connected to the adhesive output end of the rubber synthesis device. The rubber synthesis device is used to synthesize rubber, and the monomer removal device is used to remove unreacted monomers from the rubber synthesized by the rubber synthesis device. The viscosity detection device is used to detect the viscosity of the base adhesive after treatment by the monomer removal device.

[0009] In some embodiments, the monomer removal device includes a flash tank, and the viscosity detection device includes an online viscometer disposed on the output pipeline of the flash tank.

[0010] In some embodiments, the device further includes: an oil filling device connected to the adhesive output end of the base adhesive supply device, an oil supply device connected to the oil filling device, a first metering device disposed between the base adhesive supply device and the oil filling device, and a second metering device disposed between the oil supply device and the oil filling device. The first metering device is used to measure the amount of adhesive output from the base adhesive supply device to the oil filling device, and the second metering device is used to measure the amount of filling oil output from the oil supply device to the oil filling device.

[0011] In some embodiments, the first metering device includes a first liquid flow meter, and the second metering device includes a second liquid flow meter.

[0012] In some embodiments, the control device is electrically connected to the first metering device and the second metering device. The amount of adhesive measured by the first metering device is fed back to the control device. The control device is used to control the amount of filling oil output by the second metering device to the oil filling device based on the dry adhesive mass percentage in the base adhesive and the amount of adhesive fed back by the first metering device.

[0013] In some embodiments, the device further includes: a coupling agent supply device and a coupling modification device connected to the coupling agent supply device, the coupling modification device also being connected to the oil-filling device, wherein the coupling agent output from the coupling agent supply device and the oil-filled adhesive output from the oil-filling device are coupled and modified within the coupling modification device.

[0014] In some embodiments, a third metering device is provided between the coupling agent supply device and the coupling modification device, the third metering device being used to meter the amount of coupling agent output from the coupling agent supply device to the coupling modification device.

[0015] In some embodiments, the third metering device is electrically connected to the control device, which controls the amount of coupling agent output from the third metering device to the coupling modification device based on the outputs of the first metering device and the second metering device.

[0016] In some embodiments, a coagulation device is also included, which is connected to the coupling modification device and is used to coagulate the adhesive output from the coupling modification device to obtain rubber particles.

[0017] Traditional methods for testing dry adhesive content involve taking a portion of the adhesive solution from the outlet of the polymerization reactor, weighing it, drying it, and then weighing the dried solution again. The change in mass before and after drying is used to determine the dry adhesive content. However, this method is time-consuming and cannot be used for real-time testing. In continuous production, the adhesive solution taken for testing may not be exactly the same as the adhesive solution used for oil filling, resulting in low accuracy of the dry adhesive content test. Experiments have shown that when oil filling is performed based on the dry adhesive content obtained through this method, the oil filling stability is poor and the pass rate is low. Based on this, some embodiments of this application provide a novel rubber preparation system, including a base rubber solution supply device, a viscosity detection device, and a control device. The viscosity detection device is used to detect the viscosity of the base rubber solution. The viscosity test time is short, enabling real-time detection. The control device obtains the dry rubber mass percentage of the base rubber solution based on the detected viscosity and the correspondence between viscosity and dry rubber mass percentage. Therefore, when using the above system for rubber production, the viscosity detection device detects the viscosity in real time and the control device provides feedback on the dry rubber mass percentage, improving the test accuracy. This, in turn, improves the oil filling stability and the first-pass oil filling qualification rate during subsequent oil filling. Attached Figure Description

[0033] Please refer to Figure 1. This application provides a rubber preparation system 10, including: a base rubber solution supply device 100, a viscosity detection device 200, and a control device 300;

[0034] The base adhesive supply device 100 is used to supply the base adhesive.

[0035] The viscosity testing device 200 is used to test the viscosity of the base adhesive supplied by the base adhesive supply device 100;

[0036] The control device 300 is electrically connected to the viscosity detection device 200 and is used to determine the dry adhesive content in the base adhesive solution based on the viscosity detected by the viscosity detection device 200 and the correspondence between viscosity and dry adhesive mass percentage.

[0037] Traditional methods for testing dry adhesive content involve taking a portion of the adhesive solution from the outlet of the polymerization reactor, weighing it, drying it, and then weighing the dried solution again. The percentage of dry adhesive in the solution is determined by the change in mass before and after drying. However, this method is time-consuming and cannot be used for real-time testing. In continuous production, the adhesive solution taken for testing may not be exactly the same as the adhesive solution used for oil filling, resulting in low accuracy of the dry adhesive content test. Experiments have shown that when oil filling is performed based on the dry adhesive content obtained through this method, the oil filling stability is poor and the pass rate is low. Based on this, some embodiments of this application provide a novel rubber preparation system 10, including a base rubber supply device 100, a viscosity detection device 200, and a control device 300. The viscosity detection device 200 is used to detect the viscosity of the base rubber, and the viscosity test time is short, enabling real-time detection. The control device 300 obtains the dry rubber mass percentage of the base rubber based on the detected viscosity and the correspondence between viscosity and dry rubber mass percentage. Therefore, when using the above system for continuous production, the viscosity detection device 200 detects the viscosity in real time and the control device 300 feeds back the dry rubber mass percentage, improving the test accuracy. This, in turn, improves the oil filling stability and the first-pass oil filling qualification rate during subsequent oil filling.

[0038] Furthermore, traditional dry rubber content testing suffers from low accuracy. During oil filling, direct oil filling experiments exhibit poor stability and large fluctuations in oil volume, resulting in a low first-time oil filling pass rate. Conversely, using a two-time oil filling method leads to low efficiency and high cost. However, the rubber preparation system 10 in some embodiments of this application includes a base rubber solution supply device 100, a viscosity detection device 200, and a control device 300. The coordinated operation of these three components improves the accuracy of dry rubber content testing, thereby increasing the first-time oil filling pass rate, reducing costs, and improving efficiency.

[0039] In some embodiments, please refer to FIG2 as well. The base adhesive supply device 100 includes a rubber synthesis device 110 and a monomer removal device 120 connected to the adhesive output end of the rubber synthesis device 110. The rubber synthesis device 110 is used to synthesize rubber, the monomer removal device 120 is used to remove unreacted monomers from the rubber synthesized by the rubber synthesis device 110, and the viscosity detection device 200 is used to detect the viscosity of the rubber after treatment by the monomer removal device 120.

[0040] Specifically, the rubber synthesis apparatus 110 is used to polymerize monomers under the action of a catalyst to generate a base rubber compound. Considering the continuous production of the rubber compound, in order to extend the polymerization reaction time and improve the polymerization conversion rate, the rubber synthesis apparatus 110 preferably includes at least two polymerization reactors connected in series, and more preferably includes at least three polymerization reactors connected in series. In one example, the rubber synthesis apparatus 110 includes a first polymerization reactor, an intermediate polymerization reactor, and a final polymerization reactor connected in series.

[0041] It is understood that in some other embodiments, the base adhesive supply device 100 may also include an adhesive storage tank for storing the base adhesive synthesized by reaction.

[0042] In some embodiments, the base adhesive supply device 100 further includes a terminator feed pipe for introducing a terminator into the rubber synthesis apparatus 110. The introduction of the terminator into the rubber synthesis apparatus 110 through the terminator feed pipe terminates the polymerization reaction.

[0043] In some embodiments, the base adhesive supply device 100 further includes a catalyst feed pipe (not shown) for introducing a catalyst into the rubber synthesis device 110.

[0044] In some embodiments, the base adhesive supply device 100 further includes a catalyst aging device (not shown) for aging the catalyst and is connected to the rubber synthesis device 110 for feeding the aged catalyst into the rubber synthesis device 110. Specifically, the catalyst aging device introduces the catalyst into the rubber synthesis device 110 through a catalyst feed pipe.

[0045] In one example, the catalyst aging device can be an aging kettle.

[0046] In some embodiments, the base adhesive is, but not limited to, a polybutadiene rubber adhesive. In this case, the monomer includes butadiene. In one example, the base adhesive includes a cis-butadiene rubber adhesive. It will be understood that in other embodiments, the base adhesive may also include other types of rubber.

[0047] In some embodiments, the catalyst is a rare earth catalyst, and the oil-extended cis-butadiene rubber prepared using a rare earth catalyst exhibits excellent properties. It is understood that in other embodiments, the catalyst may also be other types of catalysts, such as nickel-based catalysts.

[0048] The monomer removal device 120 is used to remove unreacted monomers from the base rubber solution synthesized by the rubber synthesis device 110, and the viscosity detection device 200 is used to detect the viscosity of the base rubber solution after treatment by the monomer removal device 120. It can be understood that if the conversion rate of monomers in the rubber synthesis device 110 is 100%, or if it does not contain unreacted monomers, the monomer removal device 120 can also be omitted.

[0049] In some embodiments, the monomer removal device 120 includes a flash tank. Unreacted monomers, such as butadiene monomers, can be removed by the flash tank. It will be understood that in other embodiments, the monomer removal device 120 is not limited to a flash tank, but may be other devices capable of removing monomers.

[0050] In some embodiments, the viscosity detection device 200 includes an online viscometer. An online viscometer is an instrument used for online measurement of liquid viscosity, typically installed on a production line to monitor and control the liquid viscosity in real time. The online viscometer allows for real-time viscosity detection and, in conjunction with the control device 300, can more accurately reflect the dry adhesive mass percentage in the adhesive solution based on the viscosity reading.

[0051] In some embodiments, the monomer removal device 120 includes a flash tank, and the viscosity detection device 200 includes an online viscometer disposed on the output pipeline of the flash tank.

[0052] In some embodiments, the control device 300 stores the correspondence between viscosity and dry adhesive mass percentage.

[0053] It is understandable that the relationship between viscosity and dry rubber mass percentage refers to the relationship between the viscosity of the adhesive solution after monomer removal and the dry rubber mass percentage. If the base adhesive solution has not had monomers removed, the conversion rate and monomer content may vary with each adhesive solution test, affecting subsequent viscosity tests. Therefore, treating the base adhesive solution synthesized by the rubber synthesis device 110 through the monomer removal device 120 to remove unreacted monomers before testing its viscosity helps improve the accuracy and stability of the viscosity test.

[0054] In some embodiments, referring to Figures 2 and 3, the rubber preparation system 10 further includes: an oil filling device 400 connected to the rubber output end of the base rubber supply device 100, an oil supply device 500 connected to the oil filling device 400, a first metering device 102 disposed between the base rubber supply device 100 and the oil filling device 400, and a second metering device 502 disposed between the oil supply device 500 and the oil filling device 400. The first metering device 102 is used to meter the amount of rubber output from the base rubber supply device 100 to the oil filling device 400, and the second metering device 502 is used to meter the amount of filling oil output from the oil supply device 500 to the oil filling device 400.

[0055] The rubber preparation system 10 described above outputs the dry rubber mass percentage through the cooperation of the viscosity detection device 200 and the control device 300. Based on the obtained dry rubber mass percentage, the first metering device 102 and the second metering device 502 accurately measure and output the amount of filling oil and rubber solution to the oil filling device 400, thereby improving the first-time oil filling pass rate and oil filling stability. In actual production, the mass of dry rubber in the rubber solution is obtained based on the mass percentage of dry rubber in the base rubber solution and the amount of rubber solution measured by the first metering device 102. Then, based on the ratio of dry rubber mass to filling oil, the amount of filling oil to be delivered to the oil filling device 400 is obtained. The amount of filling oil measured by the second metering device 502 is adjusted.

[0056] In one example, the first metering device 102 includes a first liquid flow meter, and the second metering device 502 includes a second liquid flow meter. The liquid flow meters allow for accurate measurement of the amount of adhesive and filler oil, and also enable flow rate adjustment. Specifically, based on the mass percentage of dry adhesive in the base adhesive, the amount of adhesive measured by the first metering device 102, and the mass ratio of filler oil to dry adhesive, the amount of filler oil is determined. The flow rate is then adjusted and measured by the second flow meter, ensuring that the adhesive and filler oil are introduced into the filling device 400 in a specific ratio.

[0057] In some embodiments, the control device 300 is electrically connected to the first metering device 102 and the second metering device 502. The amount of adhesive measured by the first metering device 102 is fed back to the control device 300. The control device 300 controls the amount of filling oil output by the second metering device 502 to the oil filling device 400 based on the dry adhesive mass percentage in the base adhesive and the amount of adhesive fed back by the first metering device 102. This configuration enables automated continuous production. It is understood that in other embodiments, the output of the second metering device 502 can also be manually adjusted based on the dry adhesive mass percentage in the base adhesive and the amount of adhesive measured by the first metering device 102.

[0058] In one example, the oil filling device 400 includes an oil filling vessel. It will be understood that in some embodiments, a stirrer is also provided within the oil filling vessel to ensure thorough mixing of the filler oil and the base adhesive.

[0059] In one example, the oil supply device 500 includes an oil storage tank.

[0060] In some embodiments, the oil supply device 500 includes an oil storage tank, the oil filling device 400 includes an oil filling vessel, the oil storage tank and the oil filling vessel are connected by a first pipeline, and a first liquid flow meter is installed on the first pipeline.

[0061] In some embodiments, the monomer removal device 120 includes a flash tank, the viscosity detection device 200 includes an online viscometer, and the oil filling device 400 includes an oil filling vessel. The flash tank and the oil filling vessel are connected by a second pipeline. The online viscometer and the second liquid flow meter are both installed on the second pipeline, and the second liquid flow meter is closer to the oil filling vessel.

[0062] In some embodiments, referring to Figures 2 and 3, the rubber preparation system 10 further includes: a coupling agent supply device 600 and a coupling modification device 700 connected to the coupling agent supply device 600. The coupling modification device 700 is also connected to the oil filling device 400. The coupling agent provided by the coupling agent supply device 600 and the rubber solution output by the oil filling device 400 are coupled and modified in the coupling modification device 700.

[0063] Taking polybutadiene rubber as an example, high Mooney viscosity polybutadiene rubber has better mechanical and other properties than low Mooney viscosity polybutadiene rubber. The traditional method for preparing high Mooney viscosity polybutadiene rubber is to first prepare a high Mooney viscosity base solution, and then perform oil filling and coagulation to obtain high Mooney viscosity polybutadiene rubber. However, the above method still has the following problems: the preparation of high Mooney viscosity base solution is time-consuming and has a low conversion rate. Moreover, the high viscosity of the solution makes it difficult to transport. The subsequent oil filling process requires long-term stirring, resulting in high energy consumption. Based on this, some embodiments of this application provide a preparation system capable of obtaining polybutadiene rubber with high Mooney viscosity, low energy consumption, and easy transportation. Specifically, the rubber preparation system 10 of some embodiments of this application includes a base adhesive supply device 100, a viscosity detection device 200, a control device 300, an oil filling device 400, an oil supply device 500, a coupling agent supply device 600, and a coupling modification device 700. By adding the coupling agent supply device 600 and the coupling modification device 700, when the base adhesive supply device 100 provides a base adhesive with a medium to low Mooney viscosity (20 MU~60 MU), the viscosity is detected by the viscosity detection device 200, the dry adhesive mass percentage is output by the control device 300, and the oil filling device 400 fills the adhesive to obtain an oil-filled adhesive with a stable oil filling amount and a low Mooney viscosity (10 MU~30 MU). Further modification by the coupling modification device 700 is beneficial to improving the Mooney viscosity and mechanical properties, resulting in a Mooney viscosity of 30~ A 50 MU oil-extended adhesive solution, after coagulation, yields high Mooney viscosity polybutadiene rubber, which exhibits performance comparable to, or even superior to, high Mooney viscosity polybutadiene rubber prepared by conventional methods. Furthermore, the preparation process utilizes a base adhesive solution with high conversion rate and short processing time for medium to low Mooney viscosity, facilitating transportation and reducing pipeline blockage. Additionally, the subsequent oil-extending process is easier, exhibits better dispersion uniformity, and provides stable oil-extending quality, thus reducing energy consumption.

[0064] Therefore, the rubber preparation system 10 of some embodiments of this application can obtain polybutadiene rubber with high Mooney viscosity, and is beneficial to improving conversion rate and reducing energy consumption.

[0065] In one example, the coupling agent supply device 600 may be, but is not limited to, a coupling agent storage tank.

[0066] In one example, the coupling modification device 700 may be, but is not limited to, a coupling modification vessel.

[0067] In some embodiments, a third metering device 602 is provided between the coupling agent supply device 600 and the coupling modification device 700. The third metering device 602 is used to meter the amount of coupling agent output from the coupling agent supply device 600 to the coupling modification device 700.

[0068] By setting a third metering device 602 to accurately measure the amount of coupling agent introduced into the coupling modification device 700, the coupling modification effect and stability are improved.

[0069] In one example, the third metering device 602 includes a third liquid flow meter.

[0070] In some embodiments, the third metering device 602 is electrically connected to the control device 300, which controls the amount of coupling agent output from the third metering device 602 to the coupling modification device 700 based on the outputs of the first metering device 102 and the second metering device 502. This configuration facilitates automated control and continuous production. It is understood that in other embodiments, the output of the third metering device 602 can also be manually adjusted.

[0071] In some embodiments, referring to FIG2, the rubber preparation system 10 further includes a coagulation device 800, which is connected to the coupling modification device 700 and is used to coagulate the adhesive solution output from the coupling modification device 700 to obtain rubber particles. Specifically, the coagulation treatment refers to removing the solvent from the adhesive solution to precipitate rubber particles. The coagulation device 800 can be any commonly used in the art.

[0072] In some embodiments, the condensation device 800 includes condensation kettles. Specifically, the condensation device 800 includes at least three condensation kettles. Specifically, the condensation device 800 includes a first condensation kettle, a middle condensation kettle, and a final condensation kettle (not shown) connected in sequence, with the first condensation kettle connected to the coupling modification device 700. By providing multiple condensation kettles, it is beneficial to improve the condensation effect and achieve continuous condensation.

[0073] In some embodiments, the rubber preparation system 10 further includes a post-processing device 900 connected to the coagulation device 800 for post-processing the coagulated rubber. Specifically, the post-processing device 900 includes a washing unit, a dehydration unit, and a drying unit (not shown) connected in sequence to wash, dehydrate, and dry the rubber particles.

[0074] In some embodiments, referring to Figure 3, after coupling modification and before coagulation, a step of mixing the adhesive solution is included. Specifically, the adhesive solution output from the coupling modification device 700 is mixed by the adhesive solution blending device 802, and the blended adhesive solution is then coagulated and output to the coagulation device 800.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
