After 120 DEG C, remainder SBC or SIS progressively being added, the heating nesting temperature of reactor A ibid, is set in 160-by charging process
180℃；After in material, SBC or SIS melts completely, then by vacuum feeding device by pure C9 hydrogenated petroleum resin, it is gradually added
In reactor A, low opening stirring motor, after mixing, standard-sized sheet stirring motor, after stirring and evenly mixing, by hydrogenated rosin and non-hydrogenated petroleum
Resin is gradually added, and low opens stirring motor, and after mixing, standard-sized sheet stirring motor, after resin adds, by reactor B nesting temperature
Bound is adjusted to 170-190 DEG C, and in question response still A, temperature of charge rises to 150-170 DEG C, and reactor B is carried out evacuation, material
Through vacuum automatic screen changer, thickness state material being filtered off foreign body and flows in reactor B, the material after filtration is through standing and defoaming
After, it is depressed into extruder charge door by the Melt Pump bottom reactor B, extrudes continuously to specific device through special die head, make
It squeezes in cooling water, and finally cooling is shaped to medicated pillow shape elastic glue, cases after drying.
3. a preparation facilities used, its feature in the preparation method of zero creep low temperature elastic glue according to claim 2
Being: include reactor A, this reactor A is connected with nitrogen pot, reactor B respectively, reactor A, reactor B all with vacuum pump,
Air compressor machine is connected, and installs stirring motor in reactor A, this stirring motor is installed by sticking in still wall and the mixture of bottom and
Time the anchor paddle with scraping blade that strikes off, reactor B is connected with vacuum automatic screen changer, and the material in reactor B leads to
Crossing the Melt Pump bottom it to be depressed into extruder and make it clamp-on in bosh, this bosh passes through kinetic pump and circulating refrigerator
It is connected.
Preparation facilities used in the preparation method of zero creep low temperature elastic glue the most according to claim 3, it is characterised in that:
Valve is opened up under installing on reactor B.
5. a preparation facilities used, its feature in the preparation method of zero creep low temperature elastic glue according to claim 1
Being: include interconnective reactor A, reactor B, it is connected with product pump, and this product pump is connected with heat exchanger, this heat
Exchanger connects filling apparatus, and this filling apparatus connects cooling duct, and product enters cooling tunnel through transmitting device, allotter successively
Road, cooled tunnel enters coolconveyer and is transmitted by cylinder conveyer, and wherein, heat exchanger is with heat conduction oil cooling device even
Connecing, this heat conduction oil cooling device is also respectively connected with cooling tunnel, cooling duct, cooling unit, water pump, and this water pump is logical with cooling
Road, cooling tunnel connect.
