[0068] A PVC slurry formula includes the following components by weight:

[0069] PVC paste resin: 100 parts; plasticizer: 60 - 120 parts; flame retardant: 3 - 10 parts; calcium powder: 10 - 50 parts; stabilizer: 3 - 10 parts; diluent: 10 - 40 parts; adhesive: 15 - 40 parts.

[0070] A preparation process of a PVC slurry formula includes the following operating steps:

[0071] S1: By respectively putting appropriate amounts of plasticizer, flame retardant and calcium powder into the interiors of three different storage tanks in the masterbatch storage and mixing device, the preparation work is completed;

[0072] S2: Pour an appropriate amount of PVC paste resin into the interior of the mixing tank. By rotating the rotating disk, move the masterbatch storage and mixing device to the upper end of the mixing tank. By activating the hydraulic telescopic rod, drive the rotating disk and the top disk to move downward by the hydraulic telescopic rod. At this time, the bottom of the blocking disk is inserted into the polygonal groove at the top of the mixing and stirring disk. At the same time, the pressing plug is inserted into the interior of the storage tank to perform a sealing extrusion on the plasticizer, flame retardant, and calcium powder, so that the plasticizer, flame retardant, and calcium powder are extruded out of the storage tank and stay on the upper end of the sealing disk. When the extrusion is completed, the bottom of the pressing plate contacts the top of the stirring disk, and at this time, press the stirring disk;

[0073] S3: Due to the force on the stirring disk, the stirring disk will rotate downward along the thread gap of the guiding thread on the outer wall of the rotating rod. While rotating, it can first stir the mixture on the upper end of the stirring disk. At this time, the first reset component is stressed and compressed until it is compressed to the shortest distance. At this time, the first reset component will exert the maximum pressure on the sealing disk, drive the sealing disk to move downward along the notch, and at the same time, the second reset component is compressed, so that the sealing disk moves away from the placement tank and releases the stirred mixture, which falls into the PVC paste resin until the second reset component is compressed to the shortest distance, then stop applying pressure;

[0074] S4: By activating the motor at the lower end of the mixing and stirring disk, drive the mixing and stirring disk to stir, and stir the mixed materials. At this time, the mixing and stirring disk will drive the rotating rod to rotate. Since the stirring disk and the sealing disk are still in a compressed state, the stirring disk and the sealing disk will rotate together with the mixing and stirring disk and cooperate with the mixing and stirring disk to continuously stir the upper and lower ends of the mixture. The mixer stirs at a low speed of 400 - 600 RPM for 30 minutes. During the process, clean the powder adhering to the wall. After visually checking that there is no powder in the mixture, then stir at a high speed of 800 - 1200 RPM for 10 - 20 minutes. This process accelerates the mixing and reduces the presence of bubbles;

[0075] S5: The uniformly mixed slurry is called the masterbatch. Seal the mouth of the stirring tank containing the masterbatch and place it for 5 - 7 days (in winter, the time needs to be appropriately extended due to low temperature), so that the components in the masterbatch fully react. This process is called fermentation. The fermented masterbatch presents a viscous jelly-like state, is finer and has a higher viscosity than the masterbatch before fermentation, and has a better use effect.

[0076] S6: By putting an appropriate amount of stabilizer, diluent, and adhesive into the interior of three different storage tanks in the batching storage and mixing device 6, prepare the PVC slurry;

[0077] S7: Before preparing the PVC slurry, first stir the masterbatch in the mixing tank evenly, then move the batching storage and mixing device to the upper end of the mixing tank, and repeat the operations of S2, S3, and S4, and cooperate with stirring for 10 - 15 minutes to obtain the PVC slurry.

[0078] Compared with the prior art:

[0079] By comparing the products produced from PVC slurry and unfermented glue with those obtained by the method and ingredients of this case, the products produced from fermented glue are softer, more elastic, have a better feel, the composite fastness is increased by 20 - 50 (N / 5cm), and the products are also more resistant to folding white than before;

[0080] The rotating assembly can install the masterbatch storage and mixing device and the ingredient storage and mixing device, and can rotate and adjust the positions of the masterbatch storage and mixing device and the ingredient storage and mixing device;

[0081] Inside the masterbatch storage and mixing device, plasticizers, flame retardants, and calcium powder can be separately stored and placed, and can be pressed by the pressing device, so that three groups of quantitative components are extruded. At the same time, the three components can be mixed first, and then enter the inside of the mixing assembly to be uniformly mixed with PVC paste resin;

[0082] Through the telescopic drive of the rotating assembly, the pressing device can be pressed, so that the pressing device is connected to the masterbatch storage and mixing device and the ingredient storage and mixing device, thereby driving the components in the masterbatch storage and mixing device and the ingredient storage and mixing device to be extruded, and making the components in the masterbatch storage and mixing device and the ingredient storage and mixing device be mixed and stirred first;

[0083] Through the ingredient storage and mixing device, stabilizers, diluents, and adhesives can be separately stored and placed, and can be pressed by the pressing device, so that three groups of quantitative components are extruded. At the same time, the three components can be mixed first, and then enter the inside of the mixing assembly to be uniformly mixed with the masterbatch. Brief Description of the Drawings

[0107] The ingredient storage and mixing device 6 is installed at the lower right end of the rotating assembly 3. Inside, it can separately store and place stabilizers, diluents, and adhesives, and can be pressed by the pressing device 5 so that three groups of quantified components are extruded.

[0108] A PVC slurry formula includes the following components, with the components calculated by weight:

[0109] PVC paste resin: 100 parts; plasticizer: 60 - 120 parts; flame retardant: 3 - 10 parts; calcium powder: 10 - 50 parts; stabilizer: 3 - 10 parts; diluent: 10 - 40 parts; adhesive: 15 - 40 parts.

[0110] A preparation process for a PVC slurry formula includes the following operating steps:

[0111] S1: By separately putting appropriate amounts of plasticizer, flame retardant, and calcium powder into the three different storage tanks 42 in the masterbatch storage and mixing device 4, the preparation work is completed.

[0112] S2: Pour an appropriate amount of PVC paste resin into the mixing tank 21. By rotating the rotating disk 32, rotate the masterbatch storage and mixing device 4 to the upper end of the mixing tank 21. By starting the hydraulic telescopic rod 31, the hydraulic telescopic rod 31 drives the rotating disk 32 and the top disk 33 to move downward. At this time, the bottom of the blocking disk 48 is inserted into the polygonal groove 232 at the top of the mixing and stirring disk 231. At the same time, the pressing plug 552 is inserted into the storage tank 42 to hermetically extrude the plasticizer, flame retardant, and calcium powder, so that the plasticizer, flame retardant, and calcium powder are extruded from the storage tank 42 and stay on the upper end of the sealing disk 461. When the extrusion is completed, the bottom of the pressing plate 56 contacts the top of the stirring disk 441, and at this time, the stirring disk 441 is pressed.

[0113] S3: Due to the force on the stirring disk 441, the stirring disk 441 will rotate downward along the thread gap of the guiding thread 434 on the outer wall of the rotating rod 432. While rotating, it can first stir the mixture on the upper end of the stirring disk 441. At this time, the first reset assembly 45 is stressed and compressed until it is compressed to the shortest distance. At this time, the first reset assembly 45 will exert the maximum pressure on the sealing disk 461, driving the sealing disk 461 to move downward along the notch 435. At the same time, the second reset assembly 47 is compressed, so that the sealing disk 461 moves away from the placement tank 41 and releases the stirred mixture, which drops into the PVC paste resin until the second reset assembly 47 is compressed to the shortest distance, then the pressure application stops.

[0114] S4: By starting the motor at the lower end of the mixing and stirring disc 231, drive the mixing and stirring disc 231 to agitate, and stir the mixed materials. At this time, the mixing and stirring disc 231 will drive the rotating rod 432 to rotate. Since the stirring disc 441 and the sealing disc 461 are still in a compressed state, the stirring disc 441 and the sealing disc 461 will rotate together with the mixing and stirring disc 231, and cooperate with the mixing and stirring disc 231 to continuously stir the upper and lower ends of the mixed materials. The mixer stirs at a low speed of 400 - 600 RPM for 30 minutes. During the process, clean the powder sticking to the wall. After visually checking that there is no powder in the mixture, then stir at a high speed of 800 - 1200 RPM for 10 - 20 minutes. This process accelerates the mixing and reduces the presence of bubbles.

[0115] S5: The uniformly mixed slurry is called the masterbatch. Seal the mouth of the stirring cylinder containing the masterbatch and place it for 5 - 7 days (the time needs to be appropriately extended in winter when the temperature is low), so that the components in the masterbatch can fully react. This process is called fermentation. The fermented masterbatch presents a viscous jelly-like state, is finer than the masterbatch before fermentation, has a higher viscosity, and has a better use effect.

[0116] S6: By putting appropriate stabilizers, diluents and adhesives into the interiors of three different material storage tanks 42 in the batching storage and mixing device 6, prepare the PVC slurry.

[0117] S7: Before preparing the PVC slurry, first stir the masterbatch in the mixing tank 21 evenly, then move the batching storage and mixing device 6 to the upper end of the mixing tank 21, and repeat the operations of S2, S3 and S4, and cooperate with stirring for 10 - 15 minutes to obtain the PVC slurry.

[0118] Through effect verification: Compare the products produced by the PVC slurry and the unfermented glue obtained by the method and ingredients of this case. The products produced by the fermented glue are softer, more elastic, have a better hand feeling, the composite fastness is increased by 20 - 50 (N / 5cm), and the products are also more resistant to folding and whitening than before.

In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way.
