1、Designation: D3188 06 (Reapproved 2010)Standard Test Methods forRubberEvaluation of IIR (Isobutene-Isoprene Rubber)1This standard is issued under the fixed designation D3188; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the standard materials, testformula, mixing procedures, and test methods for the evalua-t
3、ion and production control of non-halogenated isobutene-isoprene rubbers (IIR), commonly known as butyl rubber.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety c

16、3 Method BMiniature Internal Mixer Mix:6.3.1 For general mixing procedure, refer to PracticeD3182. Mix with the head temperature of the miniatureinternal mixer maintained at 60 6 3C (140 6 5F) and theunloaded rotor speed at 6.3 to 6.6 rad/s (60 to 63 rpm).6.3.2 Prepare the rubber by passing it throu

Cut the sheet into strips thatare approximately 25 mm (1 in.) wide, if desired.6.3.3 Mixing CycleSee Table 3.6.3.3.1 After mixing according to Table 3, turn off themotor, raise the ram, remove
18、the head, and discharge the batch.Measure and record the maximum batch temperature if desired.6.3.3.2 Immediately pass the discharge from the mixertwice through a standard mill maintained at 50 6 5C (122 69F) with a roll separation of 0.5 mm (0.020 in.) once, thentwice at a separation of 3 mm (0.12
19、in.) in order to dissipateheat. Pass the rolled batch endwise through the mill six timeswith an opening of 0.8 mm (0.31 in.) to enhance the dispersion.6.3.3.3 Measure and record the batch mass. If it differs fromthe theoretical value by more than 0.5 %, discard the batch.6.3.3.4 If required, cut sam
