Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 21871-2008 "rubber compound acronym", compared with GB/T 21871-2008, in addition to editorial repair Change the main technical changes are as follows. --- Added "2.5 The phosphate in ISO 1043-3 is denoted by the letter F. This standard is represented by the letter P. Because P is commonly used in Refers to phosphate and other phosphorus-containing compounds, F is commonly used to denote fluorine and its compounds, this usage will be the most Reduce material confusion to the greatest extent " --- In Chapter 3 added CLD, DMTU, DTBPC, pMBPO, PAX, PEX, PIBX, PPDC, SDBzC, SIBX, SMBT, TBSI, ZDINC thirteen abbreviations; --- Chapter Chapter 5 revised chapter title; --- Modify Chapter 6 chapter title, an increase of 6.1, an increase of NDINC, NDMC, 8HPPD three abbreviations; --- Chapter 7 Chapter revised title, an increase of 7.1, modify the TCEF TCEP, modify TOF TOP; --- Added an abbreviation for OBSH in Chapter 8; --- Added in Chapter 9 "The isocyanates listed in Table 8 are not used as rubber compounding agents, although some dimers and polymers are so the use of. The following abbreviations are listed for use in the preparation of polyurethane rubber and avoid the use of these acronyms for other Compounding agent "; --- Modify BA, DETU, EPTD, HMMA, SeDMC, TeDEC's CASRN; --- Modify CBS, HMMA, MBPP, TMTM English name; --- Modify EFA, MbOCA, MPBM, PbDMC, TAC, TAIC, TBCP, TBPB, TMPTM, TMTM, ZEPC, ZPMC, PEG, PPG, CTP, AANA, p-BBp14, o-1BBPp11, BHA, DSTDP, p-IPBp 7PPD, 77PD, 8PPD, 88PD, BDSH, CHDI, NDI, the chemical name of TIPT; --- Modify DBPC, MbOCA, MBSS, MPBM, TAC, TAIC, TeDEC, TMPTM, ZDNC, ZPMC, PPG, CTP, HITM, p-BBp14, o-1BBPp11, BHA, 8PPD, 88PD, BDSH, CHDI, NDI, TIPT, TMXDI, TTI's IUPAC name. This standard uses the translation method identical with ISO 6472.2010 "rubber compound symbols and abbreviations." This standard made the following editorial changes. --- In Table 1, Table 2, Table 3, Table 5, Table 6, Table 7, Table 8 serial number added.

1 Scope

This standard specifies the known, specific chemical composition of rubber compound symbols and abbreviations.

2 symbols to use

2.1 The symbols and acronyms used in this standard are commonly used in industry and commerce and are not named after any system. This standard and the existing business Product name and trademark name is not contradictory, but its complement. 2.2 When symbols and abbreviations first appear in a text, they should be placed in parentheses and placed after the detailed chemical name. 2.3 The standard abbreviations are not comprehensive, other new rubber compounding acronyms will be added to the standard amendments. 2.4 This standard provides IUPAC name, generic chemical name and CASRN. Under certain conditions, to provide recognized other commonly used chemistry name. 2.5 In ISO 1043-3 phosphate with the letter F said that this standard is represented by the letter P. Because P is commonly used to indicate phosphate and its He contains phosphorus compounds, F is commonly used to denote fluorine and its compounds, this use will minimize the use of this standard substances Confused.
