DETAILED DESCRIPTION

[0033] A preparation process of polyurethane fireproof adhesive, comprising the following steps

[0034] Step 1: Add black material and white material into the tank successively;

[0035] Step 2: Add dimethyl ether and propane and butane through the valve on the tank;

[0036] Step 3: Close the valve on the tank and the black and white material adding port;

[0037] Step 4: Use a shaking device to shake the tank in multiple directions.

[0038] In addition, as an example, Figure 3 As shown, this example solves the problem of fixing multiple finished product tanks containing colloidal raw materials that need to be shaken and mixed.

[0039] Since multiple placement grooves 105 are arranged on the placement portion 101, multiple fixing rings 302 are fixedly connected to the placement portion 101, multiple clamping bodies 301 are respectively slidably connected in the multiple fixing rings 302, and multiple screws are respectively threadedly connected to the multiple fixing rings 302. When using this device, multiple finished cans containing colloidal raw materials that need to be shaken and mixed are placed in the multiple placement grooves 105 on the placement portion 101, and then the multiple clamping bodies 301 slidably connected in the multiple fixing rings 302 are slid to clamp the multiple finished cans. After the multiple clamping bodies 301 clamp the multiple finished cans, the multiple screws are tightened to fix the multiple clamping bodies 301, so that the multiple clamping bodies 301 clamp and fix the multiple finished cans, which is convenient for subsequent shaking and mixing operations.

[0040] In addition, as an example, Figure 2 , Figure 4 As shown, this example solves the problem of causing the placement unit 101 to shake in the horizontal direction.

[0041] Since the two sliders Ⅰ103 are rotatably connected with the placement part 101, the two sliding columns Ⅰ201 are slidably connected with two sliders Ⅰ103, the two sliders Ⅱ205 are fixedly connected with two sliding columns Ⅰ201, the two sliding columns Ⅱ203 are slidably connected with two sliders Ⅱ205, the two sliding columns Ⅱ203 are slidably connected with two sliders Ⅱ205, the two sliding columns Ⅱ203 are slidably connected with two sliders Ⅱ205, one end of a plurality of springs Ⅰ204 is fixedly connected to the two sliding columns Ⅱ203, the other end of a plurality of springs Ⅰ204 is fixedly connected to the two sliders Ⅱ205, and the two sliding parts Ⅰ403 are fixedly connected with two sliders Ⅱ205. When using the device, by pushing the sliding part Ⅰ403, the sliding part Ⅰ403 drives the slider Ⅱ205 to slide on the sliding column Ⅱ203, the slider Ⅱ205 slides on the sliding column Ⅱ203, thereby driving the slider Ⅰ103 and the slider Ⅱ205 to slide in the same direction, and the sliding of the slider Ⅰ103 drives the placement When the sliding part Ⅰ403 on one side is pushed and the thrust is removed, the multiple springs Ⅰ204 will give the sliding part Ⅰ403 a force to return to the original position, so that the sliding part Ⅰ403 returns to the unpushed position to prepare for the next push, so that the sliding part Ⅰ403 can be pushed multiple times in a cycle, so that the placement part 101 can be continuously shaken in the horizontal direction, so as to achieve the goal of shaking and mixing the multiple finished product cans containing colloidal raw materials. Compared with the traditional process, shaking and mixing the multiple finished product cans containing colloidal raw materials can avoid the uncontrolled volatilization of gas during the mixing process during external mixing, making it difficult to achieve the effect of complete mixing of gas and liquid, and can avoid the problem that a large amount of colloid is adhered to the mixing vessel after external mixing and cannot be completely taken out for finished product packaging.

[0042] In addition, as an example, Figure 2 , Figure 4 As shown, this example solves the problem that the placement portion 101 shakes in the horizontal direction and drives the placement portion 101 to slide in the vertical direction.

[0043] Since two sliders Ⅱ 205 are respectively fixedly connected to one end of two springs Ⅱ 202, two sliders Ⅰ 103 are respectively fixedly connected to the other end of two springs Ⅱ 202, two sliding parts Ⅱ 402 are respectively fixedly connected to two sliders Ⅰ 103, two matching slideways 401 are respectively slidably connected to two sliding parts Ⅱ 402 and two sliding parts Ⅰ 403, two sliding parts Ⅱ 402 are respectively slidably connected to the two sliding parts Ⅰ 403, when the sliding part Ⅰ 403 is pushed to slide, the sliding part Ⅱ 402 slides in the matching slideway 401, and since the upper side of the matching slideway 401 is an inclined surface, the sliding part Ⅱ 402 will gradually slide into the sliding part Ⅰ 403, and the sliding part Ⅱ 402 will gradually slide into the sliding part Ⅰ 403, which will drive the placement part 101 to gradually slide on the sliding column Ⅰ 201, thereby reaching the placement position. The part 101 shakes in the horizontal direction and drives the placement part 101 to slide in the vertical direction. At the same time, the placement part 101 gradually slides on the sliding column Ⅰ201, which drives the spring Ⅱ202 to deform, so that when the thrust is removed after pushing the sliding part Ⅰ403 on one side, the multiple springs Ⅰ204 will give the sliding part Ⅰ403 a force to return to the original position, so that in the process of the sliding part Ⅰ403 returning to the unpushed position, the spring Ⅱ202 applies a force to the slider Ⅰ103, so that in the process of the sliding part Ⅰ403 returning to the unpushed position, the placement part 101 gradually returns to the initial position in the vertical direction, thereby facilitating multiple cycles of pushing, so that the placement part 101 shakes in the horizontal position and drives itself to shake in the vertical position at the same time, thereby enhancing the mixing effect on the colloidal raw materials.

[0044] In addition, as an example, Figure 7-8 As shown, this example solves the problem of preventing the slider Ⅰ103 from being restricted in its sliding path by the sliding portion Ⅰ403.

[0045] Since the two matching notches 404 are respectively arranged on the two sliding parts I403, the two sliding blocks I103 can pass through the two matching notches 404. In the process of the two sliding blocks I103 sliding on the two sliding columns I201, due to the setting of the two matching notches 404, the two sliding parts II402 can be connected to the two sliding blocks I103 without limiting the sliding depth of the two sliding parts II402 on the two sliding parts I403. The setting of the two matching notches 404 can prevent the two sliding blocks I103 from interfering with each other during the sliding process.

[0046] In addition, as an example, Figure 6-9 As shown, this example solves the problem of applying thrust to the sliding part Ⅰ403.

[0047] Since two transmission plates 406 are respectively fixedly connected to the two sliding parts I403, and two toggle rods 705 are respectively fixedly connected to the output shafts of the two reduction motors 707, the transmission plates 406 can be toggled by the toggle rods 705. The rotation of the reduction motor 707 on one side drives the toggle rods 705 on the output shaft of the reduction motor 707 on one side to rotate. The rotation of the toggle rods 705 on one side applies a thrust to the transmission plate 406 on one side, so that the transmission plate 406 drives the sliding part I403 to move, thereby achieving the purpose of applying thrust to the sliding part I403.

[0048] In addition, as an example, Figure 8-9 As shown, this example solves the problem of switching the shaking direction of the placement unit 101.

[0049] Since the two connecting parts I501 and the two connecting parts II503 are respectively fixedly connected to the lower ends of the two matching slideways 401, the two connecting parts I501 are slidably connected with switching rods 702, and two reduction motors 707 are respectively fixedly connected at both ends of the switching rod 702. The staff slides the switching rod 702 so that one of the two toggle rods 705 can contact the transmission plate 406 on one side, thereby driving the placement part 101 to shake in one direction. After shaking for a period of time, the switching rod 702 is slid again so that the other toggle rod 705 can contact the toggle rod 705 on the other side, thereby driving the placement part 101 to shake in the opposite direction, thereby facilitating the multi-directional shaking of the placement part 101, further enhancing the effect of mixing the colloidal raw materials, making the liquid and gas mixed more evenly, thereby improving the mixing degree of the glue and improving the use effect.

[0050] In addition, as an example, Figure 6-9 As shown, this example solves the problem of preventing the transmission plate 406 from interfering with the toggle rod 705.

[0051] Since the limit strip 405 is arranged in the two matching slides 401, the two matching notches 407 are arranged in the two matching slides 401, the two positioning rings 703 and the two positioning rods 706 are respectively arranged at both ends of the switching rod 702, and the two matching notches 407 can be inserted into the two positioning rods 706. When the staff moves the switching rod 702 so that the toggle rod 705 on one side contacts the transmission plate 406 on one side, the positioning rod 706 on one side is just inserted into the matching notches 407 on one side, thereby blocking the sliding trajectory of the sliding part I403, thereby preventing the sliding part I403 from rebounding too far due to the force of the spring I204 after the toggle rod 705 toggles the transmission plate 406 and leaves the transmission plate 406, so that the toggle rod 705 cannot perform the next toggle on the transmission plate 406 as usual, thereby preventing the transmission plate 406 from interfering with the toggle rod 705.

[0052] In addition, as an example, Figure 3 , Figure 4 , Figure 6 As shown, this example solves the problem of further enhancing the shaking effect on the tank.

[0053] Since one end of a plurality of springs III 104 is fixedly connected to the placement portion 101, the other ends of a plurality of springs III 104 are respectively fixedly connected to the two sliders I 103, a rotating stop bar I 601 is fixedly connected to the matching slide 401, and a rotating stop bar II 602 is fixedly connected to the matching slide 401, when a thrust is applied to the sliding portion I 403, the placement portion 101 is shaken in the horizontal direction and the placement portion 101 is driven to slide in the vertical direction at the same time, and is blocked by the rotating stop bar II 602 during the sliding process of the placement portion 101, so that the placement portion 101 rotates an angle, and the plurality of springs III 104 are in a stretched state at this time, and when the applied thrust is removed, the sliding portion I 403 is in the process of returning to the initial position, and the plurality of springs III 104 makes the placement portion 101 return to its original position again, so that the placement portion 101 returns to the non-rotated state again, thereby achieving an effect of repeatedly rotating the placement portion 101 while the placement portion 101 slides, thereby further enhancing the shaking effect of the tank containing the colloidal raw materials.

[0054] The polyurethane fireproof adhesive prepared by the polyurethane fireproof adhesive preparation process is composed of the following raw materials in parts by weight: 25 parts of polyether polyol, 15 parts of diisocyanate, 5 parts of dimethyl ether, and 5 parts of propane and butane.

[0055] The shaking device also includes a cylinder fixing part 502, a cylinder 701 and a pushed part 704, the cylinder fixing part 502 is fixedly connected to the connecting part I501 on one side, the cylinder 701 is fixedly connected to the cylinder fixing part 502, and the pushed part 704 is fixedly connected to the switching rod 702.

[0056] In addition, as an example, Figure 9-10 As shown, this example solves the problem of driving the switching rod 702 to slide.

[0057] When it is necessary to operate the switch rod 702 to slide, the staff operates the cylinder 701 to extend and retract, thereby driving the switch rod 702 to slide in two directions, thereby driving the two toggle rods 705 to move, so as to facilitate switching to drive one of the two sliding parts Ⅰ403 to slide.
