Abstract

A process for performing section reduction mixing production by using a banburying mixing production line with a rapid cooling device comprises the following steps of a adding crude rubber, carbon black, pills and oil plants in a banbury mixer for mixing and discharging rubber when the temperature in the banbury mixer is 155-160 DEG C after 3 minutes; b enabling the rubber to be discharged in a sealed twin-screw extruder, enabling the thickness of an extrusion sheet rubber to be 5mm, receiving extrusion finished sheet rubber and enabling the extrusion finished sheet rubber to enter the rapid cooling device of the sheet rubber for cooling until the temperature is below 100 DEG C; c enabling the film to be delivered to a first open mill, adding pre-dispersion glue masterbatch pills such as accelerating agents and sulphur, and conducting cutting and rubber smashing by using a rubber turning-over roller after feeding of the pills is completed; and d sending the sheet rubber to a second open mill for penetrating in a thin mode after dispersion is completed, replenishing and mixing, discharging the film, enabling discharged sheet rubber to enter a cooling frame for cooling and building battlements. By means of the mixing process, the existing traditional mixing process with three sections or two sections is replaced with the mixing process with one section, mixing period is shortened, and electric energy, human resources and cooling water which are needed by the traditional mixing mode are greatly reduced.

Description

Use has the technology of the mixing production of the banburying refining glue production line section of subtracting of quickly cooling device

Technical field

The present invention relates to the technology that a kind of use has the mixing production of the banburying refining glue production line section of subtracting of quickly cooling device.

Background technology

The applicant's banburying production line is produced by the soft control of colleges and universities that F305 banbury, Qingdao double star Φ 660 mills, Tianjin are grand to reach the refining glue linkage production line that equipment such as batch off unit is formed; Adopt tradition refining glue mode to produce; Traditional rubber mixing technique generally is divided into 1 section female refining, 2 sections female refinings and whole refining; Most three the process banburies of sizing material, twice process of minority sizing material banbury, some sizing material can be more at the mixing number of times of banbury.

The tradition rubber mixing technique adopts the banbury multistage mixing, and the purpose of this processing method is to realize the rubber molecule chain break, mainly adopts the high-temperature oxydation cracking, and mechanical shearing is auxilliary, and its technological process is as shown in Figure 2.

Refining concrete parameter of glue such as following table when using existing device fabrication sizing material:

The shortcoming that exists has:

1, generates a large amount of carbon gels easily, influence the dispersion and the physical property of various compounding ingredients;

2, during one section sizing material binder removal because amounts of carbon black is bigger, the banbury below be open mill, dust is more, easy contaminated environment;

3, sizing material passes through banbury and mill 2 times or 3 times, need expend more electric energy, cooling water and human resources, and efficient is lower.

Summary of the invention

The purpose of this invention is to provide the technology that a kind of use has the mixing production of the banburying refining glue production line section of subtracting of quickly cooling device, this technology can reduce refining glue hop count, saves energy, cooling water, labour, and environmental protection can also be enhanced productivity.

For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:

A kind of use has the technology of the mixing production of the banburying refining glue production line section of subtracting of quickly cooling device, it is characterized in that, comprises the steps:

A, mixing with carrying out in rubber, carbon black, little medicine, the oil plant input banbury, binder removal when the banburying built-in temperature is 155-160 ℃ after 3 minutes;

B, sizing material drain in the double screw extruder of sealing, and extruding film thickness is 5mm, access after extruding in flakes to get into the film quickly cooling device and be cooled to below 100 ℃;

C, with film transport to the first mill, add the little medicines of pre-dispersed glue master batch such as promoter, sulphur, little medicine is eaten and is cut and turn over rubber roll after powder finishes and smash glue;

D, send to second mill after disperseing to finish and approach logically, replenish mixingly, slice gets into cooling frame and cools off then, builds buttress.

This rubber mixing technique changes original three sections, two sections traditional calendering process into one section calendering process; Shortened mixing cycle; Greatly reduce required electric energy, cooling water and the human resources of tradition refining glue mode; Shortened the resting period before the different hop count masterbatch of traditional refining glue mode are produced, reduced and deposited the field inner area that masterbatch needs in the workshop, reduced because the environment dust pollution that open mill causes.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is further described:

A kind of use has the technology of the mixing production of the banburying refining glue production line section of subtracting of quickly cooling device, and is as shown in Figure 1, comprises the steps:

A, mixing with carrying out in rubber, carbon black, little medicine, the oil plant input banbury, binder removal when the banburying built-in temperature is 155-160 ℃ after 3 minutes;

B, sizing material drain in the double screw extruder of sealing, and extruding film thickness is 5mm, access after extruding in flakes to get into the film quickly cooling device and be cooled to below 100 ℃;

C, with film transport to the first mill, add the little medicines of pre-dispersed glue master batch such as promoter, sulphur, little medicine is eaten and is cut and turn over rubber roll after powder finishes and smash glue;

D, send to second mill after disperseing to finish and approach logically, replenish mixingly, slice gets into cooling frame and cools off then, builds buttress.

As shown in Figure 3, the device that the present invention uses has the powerful cooling frame fast of double screw extruder, film, two Φ 660 mills, film quickly cooling device.

Refining concrete parameter of glue such as following table when using device fabrication sizing material involved in the present invention:

The processing method that adds sulphur in the mill has been strengthened the mechanical shearing intensity of sizing material greatly, the effect of the high-temperature oxydation cracking that weakened.The dispersion of carbon black and compounding ingredient is more even, avoids the generation of carbon gel, has reduced the bloom of bonding glue material, has improved the viscosity of bonding glue material.Physical properties of rubber compound tradition refining glue mode slightly improves.
