Description
Technical field
The present invention relates to a kind of double-motor dissolution kettle and using method thereof of producing chloroprene rubber adhesive agent, relate in particular to a kind of novel chloroprene rubber adhesive agent production equipment and using method thereof that agitating device and high-speed shearing device are set simultaneously in the dissolution kettle body.
Background technology
Chloroprene rubber adhesive agent is a kind of output solvent-based adhesive big, applied widely, and it is normally through operation preparations such as refining glue, colloidal sol, dissolving mixed aids.The cost of refining glue is many man-hour, and the energy consumption height is badly in need of improving.After this Kai Fa colloidal sol new technology in colloidal sol, utilizes gear pump to play outer circulation to accelerate dissolution velocity.This technology weak point be neoprene sheet at the dissolving initial stage, film still is a block, can't pass through gear pump, thereby makes process units be difficult to run well.
Summary of the invention
The purpose of this invention is to provide a kind of double-motor dissolution kettle and using method thereof of producing chloroprene rubber adhesive agent, a kind of novel chloroprene rubber adhesive agent production equipment and using method thereof that agitating device and shear are installed in the dissolution kettle body simultaneously particularly is provided.
The object of the present invention is achieved like this:
1, manufactures and designs a kind of double-motor dissolution kettle, that the body 2 of this reactor is in the middle of being is cylindric, upper and lower side is the closed container of end socket, an agitating device 1 is installed in body upper cover center, mixing speed is at 30～120 rev/mins, allow neoprene sheet be dispersed in the interior solvent of still, by solvent swell and slowly dissolving; Between dissolution kettle agitating device and cylinder inboard wall, install a high-speed shearing device 3.The feature of this high-speed shearing device 3 is, the disk 4 of 1～2 circumferential edge along the band saw tooth at the following client link of its rotating shaft, and disk diameter is 50～400mm, and the rotary speed of disk is 0～1500 rev/min.The effect of high-speed shearing device 3 is that the neoprene sheet fly-cutting that will be suspended in the solvent becomes more and more thinner particle, the neoprene rubber macromolecule is cut into little molecule, quicken swelling, the dissolving of neoprene rubber sheet, reduced the molecular weight of neoprene, thereby reduced the viscosity of neoprene solution.
2, the cylindrical shell of this double-motor dissolution kettle body and low head have partly been done chuck 5, and when agitating device 1, at a high speed cut and cut device 3 continuously during running, temperature of charge constantly rises in the still, feeds cooling water in chuck, and temperature of charge is controlled between 30～60 ℃.
3, the motor of high-speed shearing device 3 is by variable-frequency governor stepless speed regulation.During high-speed shearing device 3 operation just, the neoprene sheet lumpiness is big, and resistance is big during the disk cutting, and running speed is little; The neoprene sheet lumpiness diminishes, and after molecular weight diminishes, can improve the rotating speed of high-speed shearing device 3, gives full play to the effect of high-speed shearing device 3.
The using method that the present invention produces the double-motor dissolution kettle of chloroprene rubber adhesive agent is:
1, with solvent suction double-motor dissolution kettle, start agitating device 1, rotating speed is 30～120 rev/mins.
2, drop into neoprene sheet from the double-motor dissolution kettle manhole.
3, the variable-frequency governor output frequency is set in 10～20HZ, starts high-speed shearing device 3, the steady back speed governing of waiting to turn round is 600～1200 rev/mins, opens reactor temperature of charge digital display instrument simultaneously.
4, after high-speed shearing device 3 operating currents descend, speed-raising is to 1200～1500 rev/mins, and to double-motor dissolution kettle chuck 5 logical cooling waters, the control temperature of charge was between 30～60 ℃ when temperature of charge rose to 50 ℃.
5, sampling observes in the still in the material whether insoluble particles is arranged, and measures its viscosity, has reached requirement as dissolving, then the variable-frequency governor output frequency is reduced, and allows high-speed shearing device 3 speed drops be low to moderate below 300 rev/mins, closes the power supply of high-speed shearing device 3.
6, add other auxiliary agents, the agitating device power supply is closed in the good back of dissolving, and filtration, discharging promptly get the chloroprene rubber adhesive agent product.
Good effect of the present invention is:
1, cancelled mixing process
Original film need be placed on rubber mixing machine carry out mastication, mixing after, can drop into reactor dissolving.The rubber mixing machine of a 22kw can only refine 100～150kg film in one day, and the 500kg film can refine Wan in 3 days yet.Both taken manually, consumes energy, and operating efficiency again is not high.After the improvement, need not refine film, save artificial and power consumption, improve operating efficiency greatly.
2, shorten the colloidal sol time
Originally the dissolving film time needs 16～18 hours, improves the back and only needs 5～6 hours, and the colloidal sol time can shorten 2/3, has improved production efficiency greatly.
3, produce winter does not need heat temperature raising, guarantees product quality.
Because be that two-shipper stirs, Yi Bian and be high-speed stirred, friction produced certain heat when temperature in the kettle relied on two-shipper to stir, and was raised to desirable collosol temperature very soon, film also can be dissolved in the winter time cmpletely, the quality of stable prod.
