Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 28610-2012 "methyl vinyl silicone rubber". Compared with GB/T 28610-2012, except for editorial changes The main technical changes are as follows. --- Added some normative references (see Chapter 2); --- "Classification" modified to "brand" (see Chapter 3, Chapter 3 of the.2012 edition); --- 110 type methyl vinyl silicone rubber added grade MVQ110-0 and its technical requirements (see 4.1); --- 112 type methyl vinyl silicone rubber added grade MVQ112-0 and its technical requirements (see 4.2); --- Revised the technical index of relative viscosity average molecular weight and volatile content (see Chapter 4, Chapter 4 of the.2012 edition); --- Increase the relative viscosity average molecular weight by increasing the Mooney viscosity method (see 5.1.2 and Appendix B); --- Determination of the molar fraction of vinyl chains by adding near-infrared spectroscopy (see 5.2.2); --- Deleted the determination of molecular weight (visual method) (see Appendix E of the.2012 edition); --- The order of appendices has been adjusted (Appendix C, Appendix D, and Appendix E of this edition correspond to Appendix B, Appendix C, and Appendix D of the.2012 edition, respectively). This standard was proposed by the China Petroleum and Chemical Industry Federation.
