1、Designation: D3191 10Standard Test Methods forCarbon Black in SBR (Styrene-Butadiene Rubber)Recipeand Evaluation Procedures1This standard is issued under the fixed designation D3191; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、the year 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 procedure, and test methods for the e
3、valuationand production control of carbon blacks in styrene butadienerubber (SBR).1.2 The values stated in SI units are to be regarded as thestandard. The values in parentheses are for information only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with i
4、ts use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

IRM 21 and IRM 31 are availablefrom Akron Rubber Development Lab, 2887 Gilchrist Road, Akron, OH 44305.BFor the MIM procedure, it is recommended that a blend of compoundingmaterials be prepared to improve accuracy of the weighing of the
15、se materials.Thismaterial blend is prepared by blending a proportional mass of each material in adry powder blender such as a biconical blender or vee blender.Amortar and pestlemay be used for blending small quantities.CFor mill mixes, weigh the rubber and carbon black to the nearest 1.0 g, thesulfu
16、r and the accelerator to the nearest 0.02 g, and all of the other compoundingmaterials to the nearest 0.1 g. For MIM mixes, weigh the rubber and material blendto the nearest 0.01 g and individual pigments, if used, to the nearest 0.001 g.DTBBS is N-tert-butyl-w-benzothiazolesulfenamide.EFor the mill
17、 mixes, a batch factor should be selected to the nearest 0.5 to giveas large a total mass as possible that will not exceed 525.0 g. Calculate all partsto the nearest 0.01 part. For MIM mixes, calculate a batch factor to the nearest0.01 that will provide a 75 % loading of the mixing chamber.5. Sampli
18、ng and Sample Preparation5.1 Samples shall be taken in accordance with PracticeD1799 or Practice D1900.5.2 The carbon black shall be conditioned before weighingand mixing by heating in a Type 1B oven, as described inSpecification E145,for1hat1256 3C. The black shall beplaced in an open vessel of sui
19、table dimensions so that thedepth of black is no more than 10 mm during conditioning. Theblack conditioned as above shall be stored in a closed moisture-proof container until ready for mixing.6. Mixing Procedure6.1 For general mixing procedure refer to Practice D3182.6.1.1 Mixing shall be done with
