Rubber Mixing Method for Continuous Mixing and Rubber Mixing System Using The Same {A Match Method of Rubber for Continuous Match and System of Rubber Match}

The present invention relates to a rubber compounding method for a continuous compounding and a rubber compounding system using the same, continuous to escape the conventional method depending on the batch (batch type) blending method for the production of rubber for rubber or technical rubber The present invention relates to a rubber compounding system capable of compounding by a formula.

In the prior art, a batch mixing method is generally used in which a rubber compound for tires or rubber for technical rubbers is mixed in a predetermined amount only. In Fig. 1, reference numeral 1a denotes a master batch blending mixer for mixing various compounding materials such as raw rubber and reinforcing agent (Carbon Black) and filler (Filler). The symbol 1b shown at the bottom represents a sulfur mixing mixer (or final mixing) used for mixing and mixing a powdered chemical such as sulfur in the master batch formulation.

As shown in the upper part of the drawing, the lower end of the masterbatch mixer 1a is typically equipped with an extruder 2 and a seating roll 3 so that the rubber compounded in the mixer can be seated. .

Therefore, the raw material rubber 10 weighed and cut by the weighing conveyor 9a is mixed with various compounding materials in the masterbatch mixer 1a and seated through the extruder 2 and the sheeting roll 3. . The seating rubber (5) thus prepared is loaded via a transport belt (4), a dipping solution tank (6) containing a release solution, and a batch off machine (7) for cooling and drying. Loaded on the die 8.

In addition, a lower end of the sulfur mixing mixer 1b is typically provided with a dump mill 12 and an open mill 13 for rear sulfur mixing. The procedure is the same as that after the seating roll 3 of the masterbatch mixer 1a.

In front of the mixing material inlet of the upper end of the sulfur mixing mixer 1b, a rubber is disposed in the above-mentioned master batch mixer 1a, which has been subjected to several times of mixing, and is cut by a predetermined amount via a weighing conveyor 9b. It is weighed and fed into the mixer 1b and blended. Here, the compounded rubber is loaded and then subjected to a rolling and extrusion process.

However, in such a conventional method, the masterbatch compound is difficult and difficult to mix, and thus, the masterbatch compound is usually transferred to the sulfur blending mixer to be sulfur blended only after several mixing steps. That is, since the sulfur compounding process can only proceed through the compounding process of the upper portion of the arrow several times, there was a troublesome process.

2a and 2b is a view showing a conventional rubber continuous mixing device.

Figure 2a shows a tandem mixer (Tandem Mixer), which is a combination of the above-described two mixers up and down, that is, a master batch mixer and a sulfur batch mixer is manufactured in one body up and down. The remaining apparatus installed after the sulfur mixture mixer 21 is the same as in the above-mentioned prior art.

In the upper masterbatch mixer 20, the blending material such as raw rubber and reinforcing agent is blended to make a masterbatch rubber compound, which is immediately discharged to the lower sulfur blender 21 to be combined with chemicals such as sulfur. Go through the process.

However, in such a continuous arrangement, there is a disadvantage that it is difficult to match the appropriate temperature of the rubber that is added to the sulfur mixing mixer. That is, the temperature of the rubber introduced into the sulfur mixing mixer through the master batch mixer is about 150-160 ℃, which is not suitable for commercialization of the rubber of 100-105 ℃ temperature from the sulfur mixing mixer is difficult to commercialize There are disadvantages.

Figure 2b relates to a continuous mixer of the conventional extruder type. As shown in the figure, it has a longer configuration than the general rubber extruder. The continuous mixing device 22 of the extruder type is divided into a master batch section 22a and a sulfur blend section 22b, and is capable of injecting the blending materials into a plurality of inlets formed on the top.

In the master batch section 22a, the master batch rubber is blended with the respective compounding materials introduced into the raw material rubber inlet 23, the reinforcing agent and the filler inlet 24, and the various process material inlets 25. Proceeds to the sulfur mixing section 22b is mixed with the chemicals injected from the chemical inlet 26 is completed.

By the way, such a device does not apply sufficient power required for high elasticity raw rubber compounding to the compounding, there is a disadvantage that is not suitable for rubber production.

The present invention aims to simplify the rubber compounding process and at the same time to maximize the compounding efficiency and productivity while reducing the rubber manufacturing cost.

2 is a view showing a conventional continuous mixing device and a peripheral device,

3 is a block diagram of a rubber compounding system for continuous blending according to the present invention.

In order to achieve the above object, the rubber compounding system of the present invention is configured to continuously perform the rubber compounding by arranging the masterbatch blending mixer and the sulfur blending mixer in one serial work line, and between the two mixers. It is characterized by arranging a transport conveyor and an open mill for cooling the blended rubber.

Rubber compounding method and a rubber compounding system using the same for the continuous blending of the present invention comprises the steps of mixing and weighing raw material rubber weighed and cut through a weighing conveyor by a master batch mixer; Processing the sheet rubber through a plurality of open mills arranged under the masterbatch mixer; Transporting the processed sheet rubber through a relatively long transport conveyor; Weighing the sheet rubber with a metering conveyor and then sulfur blending with a sulfur blending mixer; Processing through a dump mill and an open mill; Passing a dipping solution tank containing a release solution to prevent adhesion of the sheet rubber to each other; And loading via a transport belt, a cooling and drying batch-off device.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in Fig. 3, the masterbatch mixer 1a and the sulfur blending mixer 1b are placed in one serial work line.

In the lower side of the masterbatch mixer 1a, four open mills 30a to 30d are arranged in a row at regular intervals.

The raw material rubber 10 measured and cut through the measuring conveyor 9a is mixed and discharged by the master batch mixer 1a, and the discharged mixing sheet rubber is processed by the open mills 30a to 30d.

A transport conveyor 32 for transporting the processed compound is installed between each open mill, and a transport conveyor having a relatively long length between the last open mill 30d and the sulfur mixing mixer 1b. (33) is located. Since the conveying conveyor 33 is sufficiently long, the sheet rubber 5 is sufficiently cooled during transportation, so that the temperature of the sheet rubber can be adjusted to an appropriate temperature required when starting mixing in the sulfur mixing mixer 1b. .

Subsequently, the sheet rubber 5 which has passed through the transportation conveyor 33 is weighed by the metering conveyor 9b to be fed into the sulfur mixing mixer 1b, and sulfur-blended by the sulfur mixing mixer 1b. Subsequently, the blended seating rubber 5 passes through the dump mill, the open mill 13 and the dipping solution tank 6, and is then transported and loaded via the batch-off device for cooling and drying.

In another embodiment of the present invention, a batch off machine may be arranged in place of the relatively long transport conveyor 33.

As described above, in the rubber compounding system for the continuous blending of the present invention, the blending step in the master batch mixer can be completed in one serial work line, thereby simplifying the work process and at the same time, good dispersibility and viscosity of the ejection compound. Can be obtained. Therefore, productivity is maximized and cost reduction can be achieved since no release solution for master batch formulation is required.
