Description

A kind of rubber production system

Technical field

The utility model relates to a kind of production system of rubber unvulcanizate.

In the preparation process of silicon rubber, with dimethyl ring body siloxanes is main raw material, and adding accounts for dimethyl ring body siloxanes thousandth to thousand/four methyl ethylene Fourth Ring body, dimethyl ring body siloxanes is under the effect of catalyzer, the open chain polyreaction takes place and generate polymer line style dimethyl polysiloxane, the open chain polyreaction also takes place and generates polymer line style methylvinyl-polysiloxane in methyl ethylene Fourth Ring body simultaneously, thereby obtains methyl vinyl silicon kautschuk.Rubber is called rubber unvulcanizate by prescription and Synergist S-421 95 through the mixing resulting glue of rubber mixing machine, and rubber unvulcanizate is a blank of making silastic product.The key step of the production technique of rubber glue is dehydration, polymerization, takes off low and plastic emitting.

When the open chain polyreaction takes place, what of water content in the quality of polymerization effect and the dimethyl ring body siloxanes are directly related, because can changing into hydroxyl, the existence of water carries out end-blocking, thereby make that the molecular weight of rubber is less, because having many end of the chains in the rubber is the polymer molecule of hydroxyl, can cause the difficulty of mixing that adds man-hour and reinforced filling mixing, also can make storage time of rubber unvulcanizate in road, back shorten, finally cause the mechanical property of silastic product to descend.Therefore, rubber raw material dimethyl ring body siloxanes is removed minor amount of water and have crucial meaning.

In polymerization process, common polymerizing reactor capacity is less, and normally 300 to 500 liters, yield poorly, efficient is low, and the molecular weight distribution of the rubber of being produced is inhomogeneous.Common polymerizing reactor adopts the steam coils heating, temperature can change along with the variation of vapor pressure, rely on fast and the frequent adjustment valve comes controlled temperature, the temperature fluctuation instability, the low then reaction of temperature not even reaction slowly, temperature height then catalyzer can lose activity, and is bigger to the polyreaction influence.In addition, the mode that common polymerizing reactor adopts open type to feed intake, in reactor, add catalyzer in polymerization stage by dog-house, molecular weight regulator, raw materials such as contents of ethylene control agent, because reactor is a vacuum, be easy to when adding auxiliary agent, suck a large amount of air and airborne moisture, very responsive to moisture when generating the polyreaction of raw-silastic continuously, because can changing into hydroxyl, the existence of water carries out end-blocking, thereby make that the molecular weight of rubber is less, and in the rubber if to have many end of the chains be the polymer molecule of hydroxyl, can cause the difficulty of mixing that adds man-hour and reinforced filling mixing, the storage time of the rubber unvulcanizate in road shortens after also can making, finally causes the mechanical property of silastic product to descend.

Low-molecular-weight line style methylvinyl-polysiloxane contained in the rubber can make rubber not reach needed elasticity, so remove the low-molecular-weight line style methylvinyl-polysiloxane in the rubber, is one of critical process of preparation silastic product.Common removes the low molecular device of rubber because vacuum and malleation are changed, and collodion silk adheres on the still wall easily, accumulates over a long period, and forms dead glue under long term high temperature, and dead glue can influence heat transfer, and influence removes low molecule effect.Dead glue is in case form, and system must unpick and wash immediately, needs the time (needing for 1 week usually) and both unpick and wash, also can contaminated material, waste many, cost is high.Common in addition rubber removes low molecular device and adopts the steam coils heating, and temperature can change along with the variation of vapor pressure, rely on fast and the frequent adjustment valve comes controlled temperature, the temperature fluctuation instability is bigger to removing low molecule influential effect.

Rubber is after process removes low molecular step, and temperature is generally at 160 ~ 170 ℃, as not cooling, can not directly pack, can only be discharged into earlier in the metal vessel, carry out packing with plastics bag and carton again after waiting cooling, cost height, efficient are low, easily pollute, and scale production is cumbersome.
