[0049] See also Figure 1 , Figure 1 It is a schematic flow chart of an embodiment of a method for manufacturing a high-compliance balloon provided in the present application.

[0050] The method for manufacturing a high-compliance balloon specifically includes the following steps:

[0051] S11: Prepare balloon mold and stock solution.

[0052] Existing high-compliance balloons can usually be expanded by injecting liquid therein, and have different shapes. A balloon mold with a matching shape can be manufactured according to shape requirements.

[0053] In this embodiment, the thermoplastic elastic material may be dissolved in a predetermined solvent to form a stock solution, wherein the thermoplastic elastic material may be a styrene-based elastic material and the solvent may be a toluene-based organic solvent.

[0054] After the stock solution is prepared, it can be placed in a set stock solution tank.

[0055] S12: Place the balloon mold vertically and immerse the axis of the balloon mold in the stock solution along the vertical direction.

[0056] The balloon mold generally includes a mold portion matching the internal shape of the balloon and a connecting portion connecting the mold portion, wherein the connecting portion can be connected to a driving mechanism. The driving mechanism can drive at least the mold portion of the balloon mold to gradually extend into the stock liquid tank, thereby making the mold portion of the balloon mold completely immersed in the stock liquid.

[0057] S13: The balloon mold is taken out from the stock solution and left to stand for a set time, so that the stock solution forms a first stable coating on the balloon mold.

[0058] After the mold portion of the balloon mold is completely immersed in the stock solution, the balloon mold can be taken out of the stock solution and left to stand for a set time, so that the stock solution forms a first stable coating on the balloon mold.

[0059] Among them, after the driving mechanism can be used to lift the balloon mold out, it can be suspended on the stock liquid tank, so that the excess raw material on the balloon mold can flow back into the stock liquid tank. By standing for a set time until the balloon mold no longer has stock liquid flowing back, a first stable coating can be formed on the balloon mold.

[0060] S14: heating the balloon mold to form the first stable coating into a first pre-film layer.

[0061] After the first stable coating is formed, the balloon mold may be heated to semi-cure the first stable coating so that the first stable coating may form a first pre-film layer.

[0062] The heating temperature can be set according to the material of the stock solution, and when forming the first pre-filming layer, the heating temperature and heating time need to be controlled so that the first stable coating is semi-cured to form the first pre-filming layer. This step is the first semi-curing treatment.

[0063] S15: Extend the balloon mold having the first pre-film layer into the stock solution in a vertical direction.

[0064] After the first semi-curing treatment is completed, the balloon mold of the first pre-filmed layer can be vertically extended into the stock solution for a second immersion.

[0065] It should be noted that the immersion speed, immersion time and immersion depth of the second immersion are the same as those of the first immersion.

[0066] S16: The balloon mold is then taken out from the stock solution, and the balloon mold is rotated 180 degrees and then left to stand for a set time, so that the stock solution forms a second stable coating on the first pre-film layer.

[0067] Then, the balloon mold after the second immersion is taken out from the stock solution, and the balloon mold is rotated 180 degrees and then left to stand for a set time, so that the stock solution forms a second stable coating on the first pre-film layer.

[0068] In this step, by ensuring that the immersion speed, immersion time and immersion depth of the second immersion are the same as those of the first immersion, the stock solution newly attached to the balloon mold after the second immersion can be the same as that of the first immersion, and then the balloon mold is rotated 180 degrees and left to stand until no stock solution flows out of the balloon mold, thereby forming a second stable coating.

[0069] S17: heating the balloon mold to form the second stable coating into a second pre-film layer.

[0070] After the second stable coating is formed, the balloon mold can be heated to semi-cure the second stable coating so that the second stable coating can form a second pre-film layer.

[0071] The heating temperature can be set according to the material of the stock solution, and when forming the second pre-filming layer, the heating temperature and heating time need to be controlled so that the second stable coating is semi-cured to form the second pre-filming layer. This step is the second semi-curing process.

[0072] Preferably, the heating temperature and heating time of the second semi-curing treatment can be set to be the same as the heating temperature and heating time of the first semi-curing treatment, respectively.

[0073] Therefore, in the solution provided in this embodiment, after the first semi-curing, the balloon mold is immersed in the stock solution, and then the second semi-curing treatment is performed, so that a balloon with uniform thickness can be formed on the surface of the balloon mold. Therefore, the required thickness uniformity of the balloon can be improved. For a high-compliance balloon, the reliability of the use of the high-compliance balloon can be improved while ensuring its thickness uniformity.

[0074] Furthermore, in this embodiment, the step of vertically placing the balloon mold and immersing the axis of the balloon mold in the stock solution along the vertical direction includes:

[0075] The balloon mold is placed vertically and inserted into the stock solution at a first set speed in the vertical direction; the first set speed is 5±2 mm / s;

[0076] The steps of taking the balloon mold out of the original liquid include:

[0077] The balloon mold is taken out of the stock solution at a second set speed, the second set speed being 2±1 mm / s. Moreover, the standing time after the balloon mold is taken out of the stock solution each time is not less than 60 seconds.

[0078] The speed of immersing the balloon mold in the stock solution for the first time can be 5±2mm / s, and the speed of taking out the stock solution can be 2±1mm / s, and the speed of immersing the balloon mold in the stock solution for the second time can also be 5±2mm / s, and the speed of taking out the stock solution can also be 2±1mm / s. The speed of immersing the balloon mold in the stock solution for the first time is set to be the same as the speed of immersing the balloon mold in the stock solution for the second time, and the speed of taking out the balloon mold from the stock solution for the first time is also equal to the speed of taking out the balloon mold from the stock solution for the second time, and the depth of the first time the balloon mold is completely immersed in the stock solution needs to be kept the same as the depth of the second time the balloon mold is completely immersed in the stock solution.

[0079] Furthermore, in this embodiment, the preparation of the stock solution specifically includes the following steps:

[0080] The thermoplastic elastic material is dissolved in a predetermined solvent and mixed uniformly to obtain a stock solution.

[0081] The thermoplastic elastic material is a styrene-based elastic material, and its components include SEBS and paraffin oil. The solvent is a toluene-based organic solvent, such as xylene, and the xylene needs to reach AR grade.

[0082] The desired stock solution can be obtained by mixing the styrene-based elastic material and the solvent in a set ratio.

[0083] Furthermore, in this embodiment, the thermoplastic elastic material is a solid particle, which can be dissolved in a solvent, and the specific steps are: adding the thermoplastic elastic material to a set solvent for mixing, and stirring until a mixed liquid without particles visible to the naked eye is obtained; then filtering the mixed liquid with a filter cloth with a set mesh number to obtain a mixed liquid. In this embodiment, when a styrene elastic material and xylene are mixed to obtain a stock solution, a filter cloth with a mesh size of 200 or more can be used to filter 1-2 times to obtain the desired stock solution.

[0084] Furthermore, in some embodiments, after the balloon mold is heated in step S17 to form the second stable coating into the second pre-film layer, the balloon mold and the film layer formed thereon may be further processed to obtain the desired high-compliance balloon, specifically comprising the following steps:

[0085] S21: Extend the balloon mold having the second pre-film layer into the stock solution so that the stock solution submerges the balloon mold.

[0086] S22: The balloon mold is taken out from the stock solution and left to stand for a set time, so that the stock solution forms a third stable coating on the balloon mold.

[0087] In this step, the balloon mold is taken out from the original liquid and left to stand for a set time, and the standing time is also not less than 60s.

[0088] Among them, in step S21, the immersion speed of the balloon mold with the second pre-film layer into the stock solution can also be set to the same as the first set speed described above, and the depth of the balloon mold inserted into the stock solution is the same as in the previous step; and in step S22, the speed of taking the balloon mold out of the stock solution can also be set to the same as the second set speed described above.

[0089] S23: Rotate the balloon mold to a horizontal direction, and rotate the balloon mold along a straight line set in the horizontal direction as a rotation axis.

[0090] After the standing still is completed, the balloon mold is further rotated to a horizontal direction, and the balloon mold is rotated along a straight line arranged in the horizontal direction as a rotation axis.

[0091] S24: heating the balloon mold to form a high-compliance balloon on the balloon mold.

[0092] In this step, the balloon mold may be heated to form a highly compliant balloon on the balloon mold.

[0093] Specifically, if semi-curing heating is performed in both step S14 and step S17, in this step, the balloon mold and the film layer formed thereon (including the first pre-film layer, the second pre-film layer and the new film layer formed on the surface of the second pre-film layer as described above) are heated as a whole, so that the film layer as a whole can be cured to form a highly compliant balloon with a set shape.

[0094] S25: Separating the balloon mold from the high-compliance balloon.

[0095] Furthermore, the desired high-compliance balloon can be obtained by separating the balloon mold from the high-compliance balloon.

[0096] In this embodiment, heating the balloon mold to form the coating into a first pre-filming layer includes: heating the balloon mold at a first set temperature for a first set heating time to form the first stable coating into the first pre-filming layer;

[0097] Heating the balloon mold to form the second stable coating into a second pre-filmed layer, comprising: heating the balloon mold at a first set temperature for a first set heating time to form the second stable coating into the second pre-filmed layer;

[0098] Heating the balloon mold to form a high-compliance balloon on the balloon mold, including: heating the balloon mold at a second set temperature to form a high-compliance balloon on the balloon mold;

[0099] The second set temperature is lower than the first set temperature. Further heating is performed at the lower second set temperature, and the heating time at the second set temperature is set to be longer than the heating time at the first set temperature, so that the first pre-film layer, the second pre-film layer, and the new film layer formed on the surface of the second pre-film layer on the balloon mold can be uniformly heated and finally formed into the desired high-compliance balloon.

[0100] It should be noted that the method of step S11 to step 17 is a set of operations, and the operation can be repeated for a set number of groups, and then the method of step S21 to step S25 is performed to obtain a high-compliance balloon with a set thickness.

[0101] Among them, it is more preferred that when heating to form the first pre-film layer, the second pre-film layer and the new film layer formed on the surface of the second pre-film layer respectively, the balloon mold can be made to rotate axially at a set speed; and the rotation speeds of the three are set to the same, which can further ensure the uniformity of the thickness of the high-compliance balloon finally formed.

[0102] Furthermore, based on the same inventive concept, the present application also provides a manufacturing device for a high-compliance balloon.

[0103] See also Figure 2 , Figure 2 It is a structural schematic diagram of an embodiment of a manufacturing device for a compliant balloon provided in the present application.

[0106] The rotating mechanism is installed on the lifting platform, and the rotating mechanism includes a rotating power mechanism 231 and an output end 232 located at the rotating power mechanism 231. The output end 232 is used to install the balloon mold A, and the rotating power mechanism 231 is used to drive the balloon mold A to rotate in the vertical direction.

[0107] In this embodiment, it should be noted that one end of the balloon mold A is connected to the output end 232, and the other end is arranged toward the original liquid tank 240. The end of the balloon mold A facing the original liquid tank 240 can be gradually extended into the original liquid tank 240 by the lifting mechanism 220, and then the rotating power mechanism 231 can control the balloon mold A to rotate in the vertical direction after the lifting mechanism 220 brings the balloon mold A out of the original liquid tank 240, so that the end of the balloon mold A facing the original liquid tank 240 is finally rotated 180° and then arranged in a direction away from the original liquid tank 240. That is, the balloon mold A is inverted.

[0108] Among them, in this embodiment, the parameters such as the lifting time and lifting speed of the balloon mold A can be set according to the manufacturing method of the high-compliance balloon described above, and no further elaboration is made here.

[0110] Furthermore, in the present embodiment, there are multiple heating devices, and the multiple heating devices are respectively provided for the balloon mold A to extend into from different directions to heat the balloon mold A, and the output ends of adjacent rotating power mechanisms 231 are arranged.

[0111] In an optional embodiment, the number of the heating devices is three, namely a first heating device 251 , a second heating device 252 and a third heating device 253 .

[0112] Among them, the opening of the first heating device 251 is set vertically upward, for allowing the balloon mold A to enter for heating after entering the original liquid tank 240 for the first time and completing standing still, so as to perform the first semi-curing treatment to form a first pre-film layer; the opening of the second heating device 252 is set vertically downward, for allowing the balloon mold A to enter for heating after entering the original liquid tank 240 for the second time and completing standing still, so as to perform the second semi-curing treatment to form a second pre-film layer; the opening of the third heating device 253 is set in the horizontal direction, for allowing the balloon mold A to enter in the horizontal direction after entering the original liquid tank 240 for the third time and completing standing still, so as to achieve final curing to obtain the desired high-compliance balloon.
