Description

Technical Field

[0001] This invention relates to the field of rubber preparation, specifically to a method for preparing methylphenyl silicone rubber and a distillation apparatus. Background Technology

[0002] Methylphenyl silicone rubber is a type of silicone rubber. Its main advantages are low glass transition temperature and good radiation resistance. It can be produced by hydrolysis and co-condensation of dimethyl organosilicon monomers and phenyl organosilicon monomers. When preparing the rubber, liquid rubber needs to be injected into the distillation device, a solvent mixture and a large amount of water are added, and the mixture is heated to a boiling state at high temperature. After the liquid is evaporated, solid rubber condensed into bean-sized pieces can be obtained. This provides technical inspiration for the distillation device. The study of distillation apparatus revealed the following problems: Since the raw material of methyl phenyl silicone rubber before distillation is a mixture of a large amount of solvent and a large amount of water, and the solvent mixture is viscous, when water accumulates inside the solvent mixture, the distillation device needs to distill the raw material for a long time in order to evaporate the water inside the raw material. The distillation device can usually only use a stirring support and a motor to stir the raw material in a uniform direction to assist the distillation device in distillation. Currently, the prior art CN112403027A discloses a distillation device with a filtration structure for extracting Eucommia ulmoides rubber. The invention's sliding door forms a sliding structure with an outer slide rail, a sliding block, and the machine body, which facilitates the user to disassemble and assemble the combustion heating mechanism inside the machine body. For example, when the user needs to perform large-scale repairs and cleaning of the machine body, the sliding door can be pushed upward through the sliding structure formed between the outer slide rail and the sliding block, and the wiring harness connecting the combustion heating mechanism and the upper distillation zone can be unplugged. This invention primarily addresses the problem of the need for prolonged distillation of rubber raw materials in distillation apparatus. Summary of the Invention

[0010] As a further aspect of the present invention: the long blades and short blades are arranged vertically in a matching configuration, the length of the long blades is 3-6 cm longer than the length of the short blades, and multiple sets of long blades and short blades are provided on the outer side of the output shaft, while adjacent long blades and short blades on the outer side of the output shaft are arranged in an alternating pattern.

[0011] As a further aspect of the present invention: one end of the connecting rod is connected to the short blade, the short blade is linked to the weight through the connecting rod and the rotating shaft, and multiple rotating shafts are provided inside the output shaft. When the short blade slides, the rotating shafts swing synchronously with the internal movement of the output shaft.

[0012] As a further aspect of the present invention: the weight is greater than 300g, the weight swings at an angle inside the output shaft via a rotating shaft, one side of the weight slides against the inner wall of the output shaft, the total weight of the short blade and the weight is greater than the weight of the long blade, and the weight of the weight is greater than the weight of the short blade.

[0013] As a further aspect of the present invention: sleeves are provided on both sides of the lower end of the distillation tank, a ball swings at the upper end of the sleeve, scrapers swing on both sides of the upper end of the ball, and a first convex strip and a second convex strip swing on both sides of the lower end of the ball, respectively.

[0014] As a further aspect of the present invention: the sleeve is located between every two sets of long blades and short blades, the inside of the sleeve is hollow, and the inner wall of the sleeve is surrounded by a groove, which is arranged in a circular shape. The first convex strip and the second convex strip slide on the upper and lower ends of the groove respectively.

[0015] As a further aspect of the present invention: the scraper is inclined upward at 15-45°, and the upper end of the scraper is vertically corresponding to each group of long blades and short blades. When the long blade swings to the lower end of the output shaft, the long blade and the scraper are perpendicularly pressed together.

[0016] As a further aspect of the present invention: both the first convex strip and the second convex strip are inclined downward at 15-35°, both the first convex strip and the second convex strip slide inside the groove of the sleeve, the weight of the second convex strip is 50g greater than the weight of the first convex strip, and when the first convex strip is at the upper end of the groove of the sleeve, the second convex strip is at the lower end of the groove of the sleeve.

[0017] As a further aspect of the present invention: a method for preparing methylphenyl silicone rubber includes the following steps, the specific operation steps of which are as follows: S1: Raw materials, fillers and methylphenylsiloxane cyclic compounds are added to the inside of the mixer in sequence. The mixer mixes the raw materials, fillers and methylphenylsiloxane cyclic compounds for 20-30 minutes. After mixing, methylphenyl silicone rubber raw material is obtained. S2: Pour the methyl phenyl silicone rubber raw material obtained after mixing into the interior of the mixing tank. Set the internal temperature of the mixing tank to below 150-180℃ and stir for 1-2 hours. S3: The feed inlet is located at the top of the distillation tank. The raw material enters the interior of the distillation tank through the feed inlet. The heating jacket inside the distillation tank heats and distills the raw material inside the distillation tank. When the motor does not drive the output shaft to rotate, the short blade is located at the lower end of the track on one side of the output shaft. S4: The motor drives the output shaft to rotate clockwise inside the distillation tank. The short blades at the lower end of one side of the output shaft first stir the rubber material inside the lower end of the distillation tank. Because the rubber material is viscous, it is squeezed to one side of the output shaft. The output shaft swings upward on the outside of the output shaft through the slider. S5: When the short blade swings upward, the angle between the short blade and the long blade decreases. The swing of the short blade can compress the rubber material inside the distillation tank. At this time, the connecting rod on one side of the short blade swings upward synchronously. The connecting rod can drive the weight to swing upward through the rotating shaft. S6: As the output shaft continues to rotate, the long blade slides from top to bottom on the outside of the output shaft. When the long blade is on one side of the lower end of the output shaft, the short blade and the weight are on the upper end of the output shaft. Since the weight of the weight is greater than the weight of the short blade, the weight swings downward through the rotating shaft using its own weight. The rotating shaft drives the short blade to swing downward through the connecting rod and the slider. S7: At this time, the angle between the short blade and the long blade decreases again. By using the swing of the short blade, the rubber material between the short blade and the long blade can be squeezed and patted, so that the short blade and the long blade can squeeze and pat the rubber material during the rotation and stirring driven by the output shaft. S8: The sleeve is positioned between every two sets of long and short blades. When the long blade on one side of the sleeve swings to the lower end of the output shaft, the long blade and the scraper on one side of the sleeve are perpendicularly pressed. Since the adjacent long and short blades on the outside of the output shaft are staggered, the long blade on the other side of the sleeve can press against the upper end of the scraper on the other side of the sleeve, so that the scrapers on both sides of the upper end of the ball can swing in sequence. When the scraper swings, the ball rotates synchronously inside the sleeve, so that the scraper can use the continuous pressing of the long blade to assist the ball in rotating at an angle. S9: When the ball swings, it drives the second protrusion to slide to the upper end of the sleeve groove. When the second protrusion is at the upper end of the sleeve groove, because the weight of the second protrusion is 50g greater than the weight of the first protrusion, the second protrusion can slide downward on the inner wall of the sleeve groove by its own weight. Thus, the second protrusion can assist one side of the ball to swing downward. When one side of the ball swings downward, the other side of the ball swings upward. Repeat the above steps so that the ball can assist the scraper to swing vertically at the lower end of the distillation tank. The successive swing of the scraper can vertically stir the rubber material at the lower end of the distillation tank. S10: After distillation, the raw material enters the open mill for processing. After processing, the methyl phenyl silicone rubber raw material is sieved using a 100-200 mesh stainless steel mesh. After sieving, solid rubber is obtained. Then, the solid rubber is extruded and molded through an extruder to complete the preparation process of this type of methyl phenyl silicone rubber.

[0018] Beneficial effects 1. When the motor of this invention does not drive the output shaft to rotate, the short blade is at the lower end of the track on one side of the output shaft. After the motor drives the output shaft to rotate clockwise, the short blade at the lower end of the output shaft first stirs into the rubber material at the lower end of the distillation tank. Since the rubber material is viscous, it is squeezed to one side of the output shaft, and the output shaft swings upward on the outside of the output shaft through the slider. 2. When the short blade swings upward, the angle between the short blade and the long blade decreases. The swing of the short blade can compress the rubber material inside the distillation tank. At this time, the connecting rod on one side of the short blade swings upward synchronously. The connecting rod can drive the weight to swing upward through the rotating shaft. 3. As the output shaft continues to rotate, the long blade slides from top to bottom on the outside of the output shaft. When the long blade is on one side of the lower end of the output shaft, the short blade and the weight are on the upper end of the output shaft. Since the weight of the weight is greater than the weight of the short blade, the weight swings downward through the rotating shaft by its own weight. The rotating shaft drives the short blade to swing downward through the connecting rod and the slider. 4. In this invention, the angle between the short blade and the long blade is reduced again. By utilizing the oscillation of the short blade, the rubber material between the short blade and the long blade can be squeezed and patted. This allows the short blade and the long blade to squeeze and pat the rubber material during the rotation and stirring driven by the output shaft, further assisting the distillation device in distilling the rubber material. This avoids the situation where the rubber material accumulates at the bottom of the distillation tank, which would require a long time to distill the rubber material. 5. The sleeve is positioned between every two sets of long and short blades. When the long blade on one side of the sleeve swings to the lower end of the output shaft, the long blade and the scraper on one side of the sleeve are perpendicularly pressed. Since the adjacent long and short blades on the outside of the output shaft are staggered, the long blade on the other side of the sleeve can press against the upper end of the scraper on the other side of the sleeve, so that the scrapers on both sides of the upper end of the ball can swing in sequence. When the scraper swings, the ball rotates synchronously inside the sleeve, so that the scraper can use the continuous pressing of the long blade to assist the ball in rotating at an angle. 6. When the ball swings, it causes the second convex strip to slide to the upper end of the sleeve groove. When the second convex strip is at the upper end of the sleeve groove, because the weight of the second convex strip is 50g greater than the weight of the first convex strip, the second convex strip can slide downward on the inner wall of the sleeve groove by its own weight. Thus, the second convex strip can assist one side of the ball to swing downward. When one side of the ball swings downward, the other side of the ball swings upward. Repeat the above steps so that the ball can assist the scraper to swing vertically at the lower end of the distillation tank. The successive swing of the scraper can vertically stir the rubber material at the lower end of the distillation tank, avoiding the accumulation of rubber material at the lower end of the distillation tank.

[0019] 7. The methylphenyl silicone rubber obtained through the above steps can form rapid distillation during the distillation stage. The long and short blades form vertical stirring and mixing, while the scrapers form horizontal stirring, enabling the distillation device to form bidirectional stirring. At the same time, the long and short blades can form vertical patting and extrusion, avoiding the situation where solid rubber accumulates at the lower end of the distillation device, which would require a long time to heat and distill the solid rubber. This improves the preparation efficiency of existing methylphenyl silicone rubber. Attached Figure Description

Detailed Implementation

[0031] Please see Figure 1-10 In this embodiment of the invention, Example 1: A method for preparing methylphenyl silicone rubber and a distillation apparatus, comprising an outer frame 1, a distillation tank 103 mounted on the upper end of the outer frame 1, a sealing cover 101 slidably sealing the opening of the distillation tank 103, a slide 102 slidably mounted on the lower end of the sealing cover 101, a motor 104 provided on the side of the distillation tank 103 away from the sealing cover 101, and a discharge pipe 105 penetrating the lower end of the distillation tank 103. Among them: outer frame 1 and distillation tank 103, the distillation tank 103 is arranged horizontally at the upper end of the outer frame 1, the interior of the distillation tank 103 is provided with a heating jacket, the heating jacket and motor 104 are connected to the power circuit through a power line, and the upper end of the distillation tank 103 is provided with a feed port. The sealing cover 101 and the slide 102 are provided. The lower end of the slide 102 has a pulley that rotates. The sealing cover 101 slides horizontally on one side of the upper end of the outer frame 1 via the slide 102. The sealing cover 101 and the opening of the distillation tank 103 are horizontally slidably sealed. The motor 104 has an output shaft 2 that rotates at one end near the distillation tank 103. The output shaft 2 rotates laterally inside the distillation tank 103. An auxiliary stirring distillation oscillating component is provided on the outside of the output shaft 2. A valve is provided at the lower end of the discharge pipe 105. The valve is manually operated. The upper end of the distillation tank 103 has a feed inlet, through which the raw material enters the interior of the distillation tank 103. The heating jacket inside the distillation tank 103 heats and distills the raw material inside the distillation tank 103. The motor 104 drives the output shaft 2 to rotate inside the distillation tank 103. Example 2: Refer to the attached instruction manual Figure 3-8 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the swing assembly includes a long blade 201, a short blade 202, a slider 203, a rotating shaft 3, a connecting rod 301, and a weight 302. The slider 203 slides at both ends on the outside of the output shaft 2. The long blade 201 and the short blade 202 swing on the outside of the output shaft 2 through the slider 203, respectively. The rotating shaft 3 is hinged to the inside of the output shaft 2. The connecting rod 301 and the weight 302 swing on both sides of the rotating shaft 3, respectively. Wherein: slider 203, output shaft 2 is provided with a track near the outside of slider 203, the track is set in a semi-circular arc shape, slider 203 slides on the outside of output shaft 2 through the track respectively, slider 203 is matched with long blade 201 and short blade 202 respectively; The output shaft 2 has a track on its outer side near the slider 203. The track has a semi-circular arc angle of 180°. Please refer to the instruction manual for details. Figure 4 As shown, this allows the slider 203 to slide on the outside of the output shaft 2. The slider 203 is matched with the long blade 201 and the short blade 202 respectively, so that the long blade 201 and the short blade 202 can swing on the outside of the output shaft 2 through the slider 203 respectively. Long blade 201 and short blade 202 are vertically matched. The length of long blade 201 is 3-6cm longer than that of short blade 202. Multiple sets of long blade 201 and short blade 202 are provided on the outside of the output shaft 2, and adjacent long blade 201 and short blade 202 on the outside of the output shaft 2 are staggered. The adjacent long blades 201 and short blades 202 on the outer side of the output shaft 2 are arranged in an alternating manner. For example, when one side of the upper end of the output shaft 2 is a long blade 201, the side of the long blade 201 is a short blade 202. The rotating shaft 3 and the connecting rod 301 are connected at one end to the short blade 202. The short blade 202 is linked to the weight 302 through the connecting rod 301 and the rotating shaft 3. The output shaft 2 is equipped with multiple rotating shafts 3. When the short blade 202 slides, the rotating shafts 3 swing synchronously with the inside of the output shaft 2. Weight 302 has a weight greater than 300g. Weight 302 swings at an angle inside the output shaft 2 via the rotating shaft 3. One side of weight 302 slides against the inner wall of the output shaft 2. The total weight of short blade 202 and weight 302 is greater than the weight of long blade 201. The weight of weight 302 is greater than the weight of short blade 202. The total weight of the short blade 202 and the weight 302 is greater than the weight of the long blade 201. This allows the short blade 202, due to its own weight and the weight of the weight 302, to be positioned at the lower end of the track on one side of the output shaft 2 when the output shaft 2 is stationary. (Refer to the instruction manual for details.) Figure 5 As shown; When the motor 104 is not driving the output shaft 2 to rotate, the short blade 202 is located at the lower end of the track on one side of the output shaft 2. After the motor 104 drives the output shaft 2 to rotate clockwise, the short blade 202 at the lower end of one side of the output shaft 2 first stirs the rubber material inside the lower end of the distillation tank 103. Because the rubber material is viscous, it is squeezed to one side of the output shaft 2. The output shaft 2 swings upward on the outside of the output shaft 2 via the slider 203. (Refer to the attached instruction manual.) Figure 6 As shown; When the short blade 202 swings upward, the angle between the short blade 202 and the long blade 201 decreases. The swing of the short blade 202 can compress the rubber material inside the distillation tank 103. At this time, the connecting rod 301 on one side of the short blade 202 swings upward synchronously. The connecting rod 301 can drive the weight 302 to swing upward through the rotating shaft 3. As the output shaft 2 continues to rotate, the long blade 201 slides from top to bottom on the outside of the output shaft 2. When the long blade 201 is on one side of the lower end of the output shaft 2, the short blade 202 and the weight 302 are on the upper end of the output shaft 2. Since the weight of the weight 302 is greater than the weight of the short blade 202, the weight 302 swings downward through the rotating shaft 3 using its own weight. The rotating shaft 3 drives the short blade 202 to swing downward through the connecting rod 301 and the slider 203. (Refer to the instruction manual appendix.) Figure 7 As shown; At this time, the angle between the short blade 202 and the long blade 201 decreases again. By utilizing the swing of the short blade 202, the rubber material between the short blade 202 and the long blade 201 can be squeezed and pounded. This allows the short blade 202 and the long blade 201 to squeeze and pound the rubber material during the rotation and stirring driven by the output shaft 2, further assisting the distillation device in distilling the rubber material. This avoids the situation where the rubber material accumulates at the bottom of the distillation tank 103, causing the distillation tank 103 to need to distill the rubber material for a long time. Example 3: Refer to the appendix of the instruction manual Figure 3 , 9 As can be seen from 10, the difference between Example 3 and Examples 1 and 2 is that sleeves 4 are provided on both sides of the lower end of the distillation tank 103, a ball 401 swings on the upper end of the sleeve 4, scrapers 402 swing on both sides of the upper end of the ball 401, and a first protrusion 403 and a second protrusion 404 swing on both sides of the lower end of the ball 401 respectively. Wherein: Sleeve 4, sleeve 4 is located between every two sets of long blades 201 and short blades 202, sleeve 4 is hollow inside, and the inner wall of sleeve 4 is surrounded by a groove, the groove is arranged in a ring shape, and the first protrusion 403 and the second protrusion 404 slide on the upper and lower ends of the groove respectively. The sphere 401 and the scraper 402 are arranged with the scraper 402 tilted upward at 15-45°. The upper end of the scraper 402 is vertically corresponding to each set of long blades 201 and short blades 202. When the long blades 201 swing to the lower end of the output shaft 2, the long blades 201 and the scraper 402 are perpendicularly pressed together. With the sleeve 4 positioned between each pair of long blades 201 and short blades 202, when the long blade 201 on one side of the sleeve 4 swings to the lower end of the output shaft 2, the long blade 201 and the scraper 402 on one side of the sleeve 4 are perpendicularly pressed. Since the adjacent long blades 201 and short blades 202 on the outside of the output shaft 2 are staggered, the long blade 201 on the other side of the sleeve 4 can press against the upper end of the scraper 402 on the other side of the sleeve 4, so that the scrapers 402 on both sides of the upper end of the ball 401 can swing in sequence. When the scraper 402 swings, the ball 401 swings at an angle inside the sleeve 4 in sync, which can be referred to as the principle of a roly-poly toy. The first protrusion 403 and the second protrusion 404 are both inclined downward at 15-35°. The first protrusion 403 and the second protrusion 404 slide inside the groove of the sleeve 4. The weight of the second protrusion 404 is 50g greater than the weight of the first protrusion 403. When the first protrusion 403 is at the upper end of the groove of the sleeve 4, the second protrusion 404 is at the lower end of the groove of the sleeve 4. When the second protrusion 404 is at the upper end of the groove of the sleeve 4, because the weight of the second protrusion 404 is 50g greater than the weight of the first protrusion 403, the second protrusion 404 can slide downward on the inner wall of the groove of the sleeve 4 by its own weight. Thus, the second protrusion 404 can assist one side of the ball 401 to tilt and swing. Please refer to the attached instruction manual. Figure 10 As shown; Wherein: the sleeve 4 is positioned between every two sets of long blades 201 and short blades 202. When the long blade 201 on one side of the sleeve 4 swings to the lower end of the output shaft 2, the long blade 201 and the scraper 402 on one side of the sleeve 4 are perpendicularly pressed. Since the adjacent long blades 201 and short blades 202 on the outside of the output shaft 2 are staggered, the long blade 201 on the other side of the sleeve 4 can press against the upper end of the scraper 402 on the other side of the sleeve 4, so that the scrapers 402 on both sides of the upper end of the ball 401 can swing in sequence. When the scraper 402 swings, the ball 401 rotates synchronously inside the sleeve 4, so that the scraper 402 can use the continuous pressing of the long blade 201 to assist the ball 401 in angular rotational swing. When the ball 401 swings, it causes the second protrusion 404 to slide to the upper end of the groove of the sleeve 4. When the second protrusion 404 is at the upper end of the groove of the sleeve 4, since the weight of the second protrusion 404 is 50g greater than the weight of the first protrusion 403, the second protrusion 404 can slide downward on the inner wall of the groove of the sleeve 4 by its own weight. Thus, the second protrusion 404 can assist one side of the ball 401 to swing downward. When one side of the ball 401 swings downward, the other side of the ball 401 swings upward. Repeating the above steps, the ball 401 can assist the scraper 402 to swing vertically at the lower end of the distillation tank 103. The successive swings of the scraper 402 can vertically stir the rubber material at the lower end of the distillation tank 103, avoiding the accumulation of rubber material at the lower end of the distillation tank. Example 4: A method for preparing methylphenyl silicone rubber includes the following steps. Specific operational steps are as follows: S1: Raw materials, fillers and methylphenylsiloxane cyclic compounds are added to the inside of the mixer in sequence. The mixer mixes the raw materials, fillers and methylphenylsiloxane cyclic compounds for 20-30 minutes. After mixing, methylphenyl silicone rubber raw material is obtained. S2: Pour the methyl phenyl silicone rubber raw material obtained after mixing into the interior of the mixing tank. Set the internal temperature of the mixing tank to below 150-180℃ and stir for 1-2 hours. S3: The upper end of the distillation tank 103 is provided with a feed port. The raw material enters the interior of the distillation tank 103 through the feed port. The heating jacket inside the distillation tank 103 heats and distills the raw material inside the distillation tank 103. When the motor 104 does not drive the output shaft 2 to rotate, the short blade 202 is located at the lower end of the track on one side of the output shaft 2. S4: The motor 104 drives the output shaft 2 to rotate clockwise inside the distillation tank 103. The short blade 202 at the lower end of one side of the output shaft 2 first stirs the rubber material inside the lower end of the distillation tank 103. Since the rubber material is viscous, it is squeezed to one side of the output shaft 2. The output shaft 2 swings upward outside the output shaft 2 through the slider 203. S5: When the short blade 202 swings upward, the angle between the short blade 202 and the long blade 201 decreases. The swing of the short blade 202 can squeeze the rubber material inside the distillation tank 103. At this time, the connecting rod 301 on one side of the short blade 202 swings upward synchronously. The connecting rod 301 can drive the weight 302 to swing upward through the rotating shaft 3. S6: As the output shaft 2 continues to rotate, the long blade 201 slides from top to bottom on the outside of the output shaft 2. When the long blade 201 is on one side of the lower end of the output shaft 2, the short blade 202 and the weight 302 are on the upper end of the output shaft 2. Since the weight of the weight 302 is greater than the weight of the short blade 202, the weight 302 swings downward through the rotating shaft 3 by its own weight. The rotating shaft 3 drives the short blade 202 to swing downward through the connecting rod 301 and the slider 203. S7: At this time, the angle between the short blade 202 and the long blade 201 is reduced again. Then, by using the swing of the short blade 202, the rubber material between the short blade 202 and the long blade 201 can be squeezed and patted, so that the short blade 202 and the long blade 201 can squeeze and pat the rubber material during the rotation and stirring driven by the output shaft 2. S8: The sleeve 4 is positioned between each pair of long blades 201 and short blades 202. When the long blade 201 on one side of the sleeve 4 swings to the lower end of the output shaft 2, the long blade 201 and the scraper 402 on one side of the sleeve 4 are perpendicularly pressed. Since the adjacent long blades 201 and short blades 202 on the outside of the output shaft 2 are staggered, the long blade 201 on the other side of the sleeve 4 can press against the upper end of the scraper 402 on the other side of the sleeve 4, so that the scrapers 402 on both sides of the upper end of the ball 401 can swing in sequence. When the scraper 402 swings, the ball 401 rotates synchronously inside the sleeve 4, so that the scraper 402 can use the continuous pressing of the long blade 201 to assist the ball 401 in angular rotational swing. S9: When the ball 401 swings, it drives the second protrusion 404 to slide to the upper end of the groove of the sleeve 4. When the second protrusion 404 is at the upper end of the groove of the sleeve 4, since the weight of the second protrusion 404 is 50g greater than the weight of the first protrusion 403, the second protrusion 404 can slide downward on the inner wall of the groove of the sleeve 4 by its own weight. Thus, the second protrusion 404 can assist one side of the ball 401 to swing downward. When one side of the ball 401 swings downward, the other side of the ball 401 swings upward. Repeat the above steps so that the ball 401 can assist the scraper 402 to swing vertically at the lower end of the inside of the distillation tank 103. The successive swings of the scraper 402 can vertically stir the rubber raw material at the lower end of the inside of the distillation tank 103. S10: After distillation, the raw material enters the open mill for processing. After processing, the methyl phenyl silicone rubber raw material is sieved using a 100-200 mesh stainless steel mesh. After sieving, solid rubber is obtained. Then, the solid rubber is extruded and molded through an extruder to complete the preparation process of this type of methyl phenyl silicone rubber. The methylphenyl silicone rubber obtained through the above steps can achieve rapid distillation during the distillation stage. The long blades 201 and short blades 202 are vertically stirred and mixed, while the scrapers 402 form a transverse stirring, enabling the distillation device to form bidirectional stirring. At the same time, the long blades 201 and short blades 202 can form vertical patting and squeezing, avoiding the situation where solid rubber accumulates at the lower end of the distillation device, which would require a long time to heat and distill the solid rubber. This improves the preparation efficiency of existing methylphenyl silicone rubber.

6. A method for preparing methylphenyl silicone rubber, characterized in that... The distillation apparatus according to any one of claims 2-5, the method for preparing methylphenyl silicone rubber includes the following steps, the specific operation steps of which are as follows: S1: Raw materials, fillers and methylphenylsiloxane cyclic compounds are added to the inside of the mixer in sequence. The mixer mixes the raw materials, fillers and methylphenylsiloxane cyclic compounds for 20-30 minutes. After mixing, methylphenyl silicone rubber raw material is obtained. S2: Pour the methyl phenyl silicone rubber raw material obtained after mixing into the interior of the mixing tank. Set the internal temperature of the mixing tank to below 150-180℃ and stir for 1-2 hours. S3: The feed inlet is provided at the upper end of the distillation tank (103). The raw material enters the interior of the distillation tank (103) through the feed inlet. The heating jacket inside the distillation tank (103) heats and distills the raw material inside the distillation tank (103). When the motor (104) does not drive the output shaft (2) to rotate, the short blade (202) is at the lower end of the track on one side of the output shaft (2). S4: The motor (104) drives the output shaft (2) to rotate clockwise inside the distillation tank (103). The short blade (202) at the lower end of one side of the output shaft (2) first stirs the rubber material inside the lower end of the distillation tank (103). Since the rubber material is viscous, it is squeezed to one side of the output shaft (2). The output shaft (2) swings upward outside the output shaft (2) through the slider (203). S5: When the short blade (202) swings upward, the angle between the short blade (202) and the long blade (201) decreases. The swing of the short blade (202) can squeeze the rubber material inside the distillation tank (103). At this time, the connecting rod (301) on one side of the short blade (202) swings upward synchronously. The connecting rod (301) can drive the weight (302) to swing upward through the rotating shaft (3). S6: As the output shaft (2) continues to rotate, the long blade (201) slides from top to bottom on the outside of the output shaft (2). When the long blade (201) is on one side of the lower end of the output shaft (2), the short blade (202) and the weight (302) are on the upper end of the output shaft (2). Since the weight of the weight (302) is greater than the weight of the short blade (202), the weight (302) swings downward through the rotating shaft (3) by utilizing its own weight. The rotating shaft (3) drives the short blade (202) to swing downward through the connecting rod (301) and the slider (203). S7: At this time, the angle between the short blade (202) and the long blade (201) is reduced again. Then, by using the swing of the short blade (202), the rubber material between the short blade (202) and the long blade (201) can be squeezed and patted, so that the short blade (202) and the long blade (201) can squeeze and pat the rubber material during the rotation and stirring driven by the output shaft (2). S8: The sleeve (4) is positioned between each pair of long blades (201) and short blades (202). When the long blade (201) on one side of the sleeve (4) swings to the lower end of the output shaft (2), the long blade (201) and the scraper (402) on one side of the sleeve (4) are perpendicularly pressed. Since the adjacent long blades (201) and short blades (202) on the outside of the output shaft (2) are staggered, the long blade (201) on the other side of the sleeve (4) can press to the upper end of the scraper (402) on the other side of the sleeve (4), so that the scrapers (402) on both sides of the upper end of the ball (401) can swing in sequence. When the scraper (402) swings, the ball (401) rotates synchronously inside the sleeve (4), so that the scraper (402) can use the continuous pressing of the long blade (201) to assist the ball (401) to rotate at an angle. S9: When the ball (401) swings, it drives the second protrusion (404) to slide to the upper end of the groove of the sleeve (4). When the second protrusion (404) is at the upper end of the groove of the sleeve (4), the weight of the second protrusion (404) is 50g greater than the weight of the first protrusion (403). The second protrusion (404) can slide down the inner wall of the groove of the sleeve (4) by its own weight. Thus, the second protrusion (404) can assist one side of the ball (401) to swing downward. When one side of the ball (401) swings downward, the other side of the ball (401) swings upward. Repeat the above steps so that the ball (401) can assist the scraper (402) to swing vertically at the lower end of the distillation tank (103). The successive swings of the scraper (402) can vertically stir the rubber material at the lower end of the distillation tank (103). S10: After distillation, the raw material enters the open mill for processing. After processing, the methyl phenyl silicone rubber raw material is sieved using a 100-200 mesh stainless steel mesh. After sieving, solid rubber is obtained. Then, the solid rubber is extruded and molded through an extruder to complete the preparation process of this type of methyl phenyl silicone rubber.
