Description

A kind of preparation method of water-based EVA treating agent Technical Field

[0001] The present invention relates to the technical field of fine chemicals, in particular to a method for preparing a water-based EVA treating agent. Background Art

[0002] During the shoe molding process, the shoe materials need to be treated first to improve the adhesion between the shoe materials and the polyurethane adhesive. The treatment solution widely used on the market now is to use a treating agent. The treating agent is a medium between the shoe materials and the adhesive, which can make the non-polar shoe materials and the polar adhesive fit tightly together.

[0003] The invention patent with authorization announcement number CN1105643 movable disk 45 discloses a water-based EVA treatment agent and a preparation method thereof. The preparation method comprises mixing an epoxy-terminated allyl polyether and a hydrogen-containing silicone oil to prepare an epoxy polyether silicone; mixing an ethylene-acrylic acid copolymer emulsion, an initiator, a monomer mixture and 3-amino-1-propylene to prepare a modified EAA emulsion; and using the obtained epoxy polyether silicone and the obtained modified EAA emulsion to prepare a water-based EVA treatment agent. Technical issues

[0004] However, after actual application by technicians in this field, it was found that the above preparation method still has some shortcomings. The most obvious one is that in the process of adding epoxy polyether silicone to the modified EAA emulsion, a small amount of epoxy polyether silicone will remain on the inner wall of the container used to hold the epoxy polyether silicone. This will not only cause waste of epoxy polyether silicone, but also affect the ratio of epoxy polyether silicone to modified EAA emulsion, thereby affecting the quality of the finished product.

[0005] In addition, after the addition of epoxy polyether silicone is completed, a large amount of raw water needs to be added to the solution. The traditional addition method takes too long to add the raw water, which has a great impact on the preparation efficiency of the water-based EVA treatment agent.

[0006] Therefore, it is necessary to invent a method for preparing an aqueous EVA treating agent to solve the above problems. Technical Solutions

The blocking ring is fixedly sleeved on the middle part of the outside of the lifting sleeve. The drive chute is opened on the top of the side of the lifting sleeve. The guide plate is fixedly sleeved on the top of the outside of the lifting sleeve.

[0011] The water-cooling mixing mechanism includes a water supply pipe, a water pump, a heat exchange cover, a mixing plate and a longitudinal scraper;

[0012] The water supply pipe is connected to the bottom end of the drive shaft through a rotary joint and is communicated with the upper chamber. The water pump is arranged on the water supply pipe. The heat exchange cover is fixedly sleeved on the outer bottom of the drive shaft. There are multiple mixing plates and longitudinal scrapers. The multiple mixing plates are evenly fixed on the outer bottom of the heat exchange cover. The multiple longitudinal scrapers are respectively fixed on the ends of the multiple mixing plates and slide in contact with the inner wall of the lower chamber.

[0013] Preferably, the rotary dripping mechanism includes a first partition plate, a first lower liquid channel, a first blocking column, a second blocking column, a movable disk and a driving rod.

[0014] Preferably, the first partition plate is slidably sleeved on the outside of the lifting sleeve and is rotatably arranged inside the reactor through a bearing, the first lower liquid channel is opened at the top of the first partition plate, the first blocking column is slidably arranged on the inside of the first lower liquid channel, the second blocking column is fixedly arranged on the top of the first blocking column, the movable disk is rotatably sleeved on the outside bottom of the lifting sleeve through a bearing and is fixedly connected to the first blocking column, and the driving rod is fixedly arranged between the first partition plate and the heat exchange cover and slides through the movable disk.

[0015] Preferably, the rapid water supply mechanism includes a second partition plate, a second lower liquid channel, a blocking plate, a first sliding pin and a first spring.

[0016] Preferably, the second partition plate is fixedly arranged at the top of the inner cavity of the reactor, the second lower liquid channel is opened at the center of the top of the second partition plate, the sealing plate is fitted on the bottom of the second partition plate and blocks the second lower liquid channel, the first sliding pin slides through the second partition plate and is fixedly connected to the sealing plate, and the first spring is sleeved on the outside of the first sliding pin.

[0017] Preferably, the scraping mechanism includes an annular scraper, a second sliding pin, a second spring and a driving slide rod.

[0019] Preferably, the preparation method of the water-based EVA treatment agent specifically comprises the following steps:

[0020] S1. The prepared epoxy polyether silicone, modified EAA emulsion and raw water are respectively input into the middle chamber, the lower chamber and the upper chamber, and the driving motor and the water pump are started at the same time. After the driving motor is started, the multiple mixing plates and the multiple longitudinal scrapers are driven to rotate through the heat exchange cover to stir the solution. After the water pump is started, the raw water that has entered the upper chamber is extracted and then input into the driving shaft. The raw water enters the heat exchange cover through the water outlet hole, and after filling the inner cavity of the heat exchange cover, it enters the driving shaft again through the water inlet hole, and finally flows back to the upper chamber through the return hole;

[0021] S2. The driving motor drives the heat exchange cover to rotate and simultaneously drives the lifting sleeve to continuously descend through the reciprocating screw thread. When the lifting sleeve descends, the driving slide rod slides upward on the inner side of the driving slide groove. At the same time, the lifting sleeve continuously drives the blocking ring and the movable plate to descend. When the movable plate descends, it drives the first blocking column to descend inside the first lower liquid channel. During this process, the heat exchange cover drives the first partition plate to continuously rotate through the driving rod.

[0022] S3. When the lowering distance of the lifting sleeve reaches a first threshold, the first blocking column moves out from the inside of the first lower liquid channel, thereby releasing the blockage of the first lower liquid channel. At this time, the first blocking column is located inside the first lower liquid channel, and then the epoxy polyether silicone in the middle chamber drips into the lower chamber through the gap between the first lower liquid channel and the first blocking column. As the first partition plate continues to rotate, the epoxy polyether silicone continues to rotate and drip;

[0023] S4, after the epoxy polyether silicone drips, it is continuously mixed with the modified EAA emulsion in the lower chamber. The raw water that continuously circulates inside the heat exchange cover continuously exchanges heat with the mixed solution through the heat exchange cover, thereby cooling the mixed solution.

[0024] S5. When the lifting sleeve descends a distance that reaches a second threshold, the epoxy polyether silicone inside the middle chamber is completely added. At this time, the blocking ring and the blocking plate are in contact with each other, the heating is stopped, and the heat preservation is carried out, and then the driving motor is started again. At this time, as the lifting sleeve continues to descend, the blocking plate drives the first sliding pin to move downward, and at the same time, the blockage of the second lower liquid channel is released. At this time, the raw water in the upper chamber quickly fills the middle chamber through the second lower liquid channel, thereby performing the first cleaning of the residual epoxy polyether silicone in the middle chamber;

[0025] S6: When the lowering distance of the lifting sleeve reaches the third threshold, the second blocking column is removed from the first lower liquid channel. At this time, the raw water quickly passes through the second lower liquid channel and the first lower liquid channel and falls into the lower chamber to mix with the mixed solution;

[0026] S7: When the lifting sleeve has descended a distance that reaches a fourth threshold, the driving slide rod slides to the top of the inner side of the driving slide groove. As the lifting sleeve continues to descend, the lifting sleeve drives the annular scraper to slide down along the inner wall of the middle chamber through the driving slide groove, the driving slide rod, and the second sliding pin, thereby causing the annular scraper to clean the epoxy polyether silicone remaining on the inner wall of the middle chamber for a second time.

[0027] S8. When the descending distance of the lifting sleeve reaches the fifth threshold, all the raw water enters the lower chamber to complete mixing, and then the finished water-based EVA treatment agent is produced. At the same time, the lifting sleeve moves to the bottom end of the reciprocating thread on the outside of the drive shaft. Subsequently, as the drive shaft continues to rotate, the lifting sleeve moves up and resets. Beneficial effects

[0028] The technical effects and advantages of the present invention are as follows:

[0029] The present invention is provided with a driving mechanism, a water-cooled mixing mechanism, a rotary dripping mechanism, a rapid water supply mechanism and a scraping mechanism, so that after the driving mechanism is started, the rotary dripping mechanism is dual-driven by the water-cooled mixing mechanism, thereby enabling the rotary dripping mechanism to perform a rotary dripping operation. Subsequently, as the driving mechanism continues to work, the driving mechanism triggers the rapid water supply mechanism, thereby causing the raw water in the upper chamber to drop rapidly while the middle chamber is cleaned for the first time. Finally, the driving mechanism triggers the scraping mechanism, thereby achieving a second cleaning of the middle chamber. Compared with similar devices and methods in the prior art, the present invention can effectively reduce the waste of epoxy polyether silicone and improve the quality of finished products. At the same time, it can also effectively shorten the time required for adding raw water, thereby improving the preparation efficiency of the water-based EVA treating agent, and is more suitable for the industrial preparation of the water-based EVA treating agent.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0037] The present invention provides a method for preparing a water-based EVA treatment agent as shown in Figures 1-5.

[0039] As shown in Figure 3, the water-cooled mixing mechanism 3 includes a water supply pipe 31, a water pump 32, a heat exchange cover 33, a mixing plate 34 and a longitudinal scraper 35, wherein the water supply pipe 31 is connected to the bottom end of the drive shaft 21 through a rotary joint and is communicated with the upper chamber, the water pump 32 is arranged on the water supply pipe 31, the heat exchange cover 33 is fixedly sleeved on the outer bottom of the drive shaft 21, and a plurality of mixing plates 34 and longitudinal scrapers 35 are provided. The plurality of mixing plates 34 are evenly fixed on the outer bottom of the heat exchange cover 33, and the plurality of longitudinal scrapers 35 are respectively fixed on the ends of the plurality of mixing plates 34 and slidably fit with the inner wall of the lower chamber.

[0040] By setting up the above structure, after the drive motor 22 is started, the multiple mixing plates 34 and the multiple longitudinal scrapers 35 are driven to rotate through the heat exchange cover 33, thereby stirring the solution. After the water pump 32 is started, it extracts the raw water that has entered the upper chamber and then inputs it into the drive shaft 21. The raw water enters the heat exchange cover 33 through the water outlet 25. After filling the inner cavity of the heat exchange cover 33, it enters the drive shaft 21 again through the water inlet 24, and finally flows back to the upper chamber through the return water hole 23. When the raw water is inside the heat exchange cover 33, the raw water continues to exchange heat with the solution in the lower chamber through the heat exchange cover 33.

[0041] As shown in Figure 4, the rotating dripping mechanism 4 includes a first partition plate 41, a first lower liquid channel 42, a first blocking column 43, a second blocking column 44, a movable disk 45 and a driving rod 46, wherein the first partition plate 41 is slidably sleeved on the outside of the lifting sleeve 26 and is rotatably arranged inside the reactor 1 through a bearing, the first lower liquid channel 42 is opened at the top of the first partition plate 41, the first blocking column 43 is slidably arranged on the inside of the first lower liquid channel 42, the second blocking column 44 is fixedly arranged on the top of the first blocking column 43, the movable disk 45 is rotatably sleeved on the outer bottom of the lifting sleeve 26 through a bearing and is fixedly connected to the first blocking column 43, and the driving rod 46 is fixedly arranged between the first partition plate 41 and the heat exchange cover 33 and slides through the movable disk 45.

[0042] By setting the above structure, when the lifting sleeve 26 descends, the movable disk 45 is driven down, and when the movable disk 45 descends, the first blocking column 43 is driven down inside the first lower liquid channel 42. During this process, the heat exchange cover 33 drives the first partition plate 41 to rotate continuously through the drive rod 46. When the first blocking column 43 is moved out from the inside of the first lower liquid channel 42, and the blockage of the first lower liquid channel 42 is released, the first blocking column 43 is located inside the first lower liquid channel 42. Subsequently, the epoxy polyether silicone located in the middle chamber drips into the lower chamber through the gap between the first lower liquid channel 42 and the first blocking column 43. As the first partition plate 41 continues to rotate, the epoxy polyether silicone continues to rotate and drip.

[0043] As shown in Figure 5, the rapid water supply mechanism 5 includes a second partition plate 51, a second lower liquid channel 52, a sealing plate 53, a first sliding pin 54 and a first spring 55, wherein the second partition plate 51 is fixedly arranged at the top of the inner cavity of the reactor 1, the second lower liquid channel 52 is opened at the center of the top of the second partition plate 51, the sealing plate 53 is fitted at the bottom of the second partition plate 51 and blocks the second lower liquid channel 52, the first sliding pin 54 slides through the second partition plate 51 and is fixedly connected to the sealing plate 53, and the first spring 55 is sleeved on the outside of the first sliding pin 54.

[0044] By setting the above structure, the blocking ring 27 is driven to descend synchronously when the lifting sleeve 26 descends. When the blocking ring 27 is fitted with the sealing plate 53 due to the descent of the lifting sleeve 26, as the lifting sleeve 26 continues to descend, the sealing plate 53 drives the first sliding pin 54 to move downward, and at the same time releases the blockage of the second lower liquid channel 52. At this time, the raw water in the upper chamber quickly fills the middle chamber through the second lower liquid channel 52, thereby cleaning the epoxy polyether silicone remaining in the middle chamber for the first time.

[0045] As shown in Figure 5, the scraper mechanism 6 includes an annular scraper 61, a second sliding pin 62, a second spring 63 and a driving slide rod 64, wherein the annular scraper 61 is fitted at the bottom edge of the second partition plate 51 and slides in contact with the inner wall of the middle chamber, the second sliding pin 62 slides through the second partition plate 51 and is fixedly connected to the annular scraper 61, the second spring 63 is sleeved on the outside of the second sliding pin 62, and the driving slide rod 64 is slidably set on the inside of the driving slide groove 28 and is fixedly connected to the second sliding pin 62.

[0046] By setting the above structure, when the lifting sleeve 26 descends, the driving slide 64 slides relatively upward on the inner side of the driving slide 28. As the lifting sleeve 26 continues to descend, the driving slide 64 slides to the top of the inner side of the driving slide 28. Subsequently, as the lifting sleeve 26 continues to descend, the lifting sleeve 26 drives the annular scraper 61 to slide down along the inner wall of the middle chamber through the driving slide 28, the driving slide 64 and the second sliding pin 62, so that the annular scraper 61 cleans the epoxy polyether silicone remaining on the inner wall of the middle chamber for a second time. Example 2

[0047] The preparation method of the water-based EVA treatment agent specifically comprises the following steps:

[0048] S1. Input the prepared epoxy polyether silicone, modified EAA emulsion and raw water into the middle chamber, lower chamber and upper chamber respectively, and start the drive motor 22 and the water pump 32 at the same time. After the drive motor 22 is started, it drives the multiple mixing plates 34 and the multiple longitudinal scrapers 35 to rotate through the heat exchange cover 33, thereby stirring the solution. After the water pump 32 is started, it extracts the raw water that has entered the upper chamber and then inputs it into the drive shaft 21. The raw water enters the heat exchange cover 33 through the water outlet 25, and after filling the inner cavity of the heat exchange cover 33, it enters the drive shaft 21 again through the water inlet 24, and finally flows back to the upper chamber through the return hole 23;

[0049] S2. The driving motor 22 drives the heat exchange cover 33 to rotate and drives the lifting sleeve 26 to continuously descend through the reciprocating thread. When the lifting sleeve 26 descends, the driving slide 64 slides upward on the inner side of the driving slide groove 28. At the same time, the lifting sleeve 26 continuously drives the blocking ring 27 and the movable disk 45 to descend. When the movable disk 45 descends, it drives the first blocking column 43 to descend inside the first lower liquid channel 42. During this process, the heat exchange cover 33 drives the first partition plate 41 to continuously rotate through the driving rod 46.

[0050] S3: When the lowering distance of the lifting sleeve 26 reaches the first threshold, the first blocking column 43 moves out from the inside of the first lower liquid channel 42, thereby releasing the blockage of the first lower liquid channel 42. At this time, the first blocking column 43 is located inside the first lower liquid channel 42, and then the epoxy polyether silicone in the middle chamber drips into the lower chamber through the gap between the first lower liquid channel 42 and the first blocking column 43. As the first partition plate 41 continues to rotate, the epoxy polyether silicone continues to rotate and drip;

[0051] S4, after the epoxy polyether silicone drips, it is continuously mixed with the modified EAA emulsion in the lower chamber, and the raw water that continuously circulates inside the heat exchange cover 33 continuously exchanges heat with the mixed solution through the heat exchange cover 33, thereby cooling the mixed solution;

[0052] S5. When the lifting sleeve 26 descends a distance that reaches the second threshold, the epoxy polyether silicone inside the middle chamber is completely added. At this time, the blocking ring 27 and the blocking plate 53 are in contact with each other, and the heating and heat preservation are stopped. Then, the driving motor 22 is started again. At this time, as the lifting sleeve 26 continues to descend, the blocking plate 53 drives the first sliding pin 54 to move downward, and at the same time, the blockage of the second lower liquid channel 52 is released. At this time, the raw water in the upper chamber quickly fills the middle chamber through the second lower liquid channel 52, thereby cleaning the residual epoxy polyether silicone in the middle chamber for the first time.

[0053] S6: When the lowering distance of the lifting sleeve 26 reaches the third threshold, the second blocking column 44 is removed from the first lower liquid channel 42. At this time, the raw water quickly passes through the second lower liquid channel 52 and the first lower liquid channel 42 and falls into the lower chamber to mix with the mixed solution.

[0054] S7: When the lifting sleeve 26 descends a distance that reaches a fourth threshold, the driving slide bar 64 slides to the top of the inner side of the driving slide groove 28. As the lifting sleeve 26 continues to descend, the lifting sleeve 26 drives the annular scraper 61 to slide down along the inner wall of the middle chamber through the driving slide groove 28, the driving slide bar 64, and the second sliding pin 62, so that the annular scraper 61 cleans the epoxy polyether silicone remaining on the inner wall of the middle chamber for a second time.

[0055] S8. When the descending distance of the lifting sleeve 26 reaches the fifth threshold, all the raw water enters the lower chamber to complete mixing, and then the finished water-based EVA treatment agent is produced. At the same time, the lifting sleeve 26 moves to the bottom end of the reciprocating thread on the outside of the drive shaft 21. Subsequently, as the drive shaft 21 continues to rotate, the lifting sleeve 26 moves up and resets.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

7. The method for preparing a water-based EVA treating agent according to claim 6, wherein: The annular scraper (61) is fitted at the bottom edge of the second partition plate (51) and is slidably fitted with the inner wall of the middle chamber. The second sliding pin (62) slides through the second partition plate (51) and is fixedly connected to the annular scraper (61). The second spring (63) is sleeved on the outside of the second sliding pin (62). The driving slide rod (64) is slidably set on the inside of the driving slide groove (28) and is fixedly connected to the second sliding pin (62).

8. The method for preparing a water-based EVA treating agent according to claim 7, wherein: The preparation method of the water-based EVA treatment agent specifically comprises the following steps: S1. The prepared epoxy polyether silicone, modified EAA emulsion and raw water are respectively input into the middle chamber, the lower chamber and the upper chamber, and the driving motor (22) and the water pump (32) are started at the same time. After the driving motor (22) is started, the plurality of mixing plates (34) and the plurality of longitudinal scrapers (35) are driven to rotate through the heat exchange cover (33), thereby stirring the solution. After the water pump (32) is started, the raw water that has entered the upper chamber is extracted and then input into the interior of the driving shaft (21). The raw water enters the interior of the heat exchange cover (33) through the water outlet (25), and after filling the inner cavity of the heat exchange cover (33), it enters the interior of the driving shaft (21) again through the water inlet (24), and finally flows back to the upper chamber through the return water hole (23); S2, the driving motor (22) drives the heat exchange cover (33) to rotate and drives the lifting sleeve (26) to continuously descend through the reciprocating screw thread. When the lifting sleeve (26) descends, the driving slide rod (64) slides relatively upward on the inner side of the driving slide groove (28). At the same time, the lifting sleeve (26) continuously drives the blocking ring (27) and the movable disk (45) to descend. When the movable disk (45) descends, it drives the first blocking column (43) to descend on the inner side of the first lower liquid channel (42). During this process, the heat exchange cover (33) drives the first partition plate (41) to continuously rotate through the driving rod (46); S3, when the descending distance of the lifting sleeve (26) reaches the first threshold value, the first blocking column (43) moves out from the inside of the first lower liquid channel (42), thereby releasing the blockage of the first lower liquid channel (42). At this time, the first blocking column (43) is located inside the first lower liquid channel (42), and then the epoxy polyether silicone in the middle chamber drips into the lower chamber through the gap between the first lower liquid channel (42) and the first blocking column (43). As the first partition plate (41) continues to rotate, the epoxy polyether silicone continues to rotate and drip; S4, after the epoxy polyether silicone drips, it is continuously mixed with the modified EAA emulsion in the lower chamber, and the raw water continuously circulated inside the heat exchange cover (33) continuously exchanges heat with the mixed solution through the heat exchange cover (33), thereby cooling the mixed solution; S5, when the descending distance of the lifting sleeve (26) reaches the second threshold value, the epoxy polyether silicone in the middle chamber is completely dripped, and the blocking ring (27) and the blocking plate (53) are in contact with each other, and the heating and heat preservation are stopped and the driving motor (22) is started again. At this time, as the lifting sleeve (26) continues to descend, the blocking plate (53) drives the first sliding pin (54) to move downward, and at the same time releases the blockage of the second lower liquid channel (52). At this time, the raw water in the upper chamber quickly fills the middle chamber through the second lower liquid channel (52), thereby cleaning the epoxy polyether silicone remaining in the middle chamber for the first time; S6, when the descending distance of the lifting sleeve (26) reaches the third threshold value, the second blocking column (44) is removed from the inside of the first lower liquid channel (42), and the raw water quickly passes through the second lower liquid channel (52) and the first lower liquid channel (42) and falls into the lower chamber to mix with the mixed solution; S7, when the descending distance of the lifting sleeve (26) reaches the fourth threshold value, the driving slide rod (64) slides to the top of the inner side of the driving slide groove (28), and as the lifting sleeve (26) continues to descend, the lifting sleeve (26) drives the annular scraper (61) to slide down along the inner wall of the middle chamber through the driving slide groove (28), the driving slide rod (64) and the second sliding pin (62), so that the annular scraper (61) cleans the epoxy polyether silicone remaining on the inner wall of the middle chamber for a second time; S8, when the descending distance of the lifting sleeve (26) reaches the fifth threshold value, all the raw water enters the lower chamber to complete mixing, thereby producing a finished water-based EVA treatment agent. At the same time, the lifting sleeve (26) moves to the bottom end of the reciprocating thread outside the drive shaft (21), and then as the drive shaft (21) continues to rotate, the lifting sleeve (26) moves up and resets.
