Foreword

This standard replaces GB/T 11409.1-1995 "rubber antioxidant, vulcanization accelerator melting point measurement method", GB/T 11409.2-1995 "Rubber antioxidant, vulcanization accelerator crystallization point measurement method", GB/T 11409.3-2003 "rubber antioxidant, vulcanization accelerator softening point Determination ", GB/T 11409.4-1989" rubber antioxidant, Determination, "the vulcanization accelerator weight loss on heating, GB/T 11409.5-1989 "Rubber antioxidant, vulcanization accelerator Determination of residue on sieve", GB/T 11409.6-2003 "rubber antioxidant, vulcanization accelerator apparent density Determination of the degree of ", GB/T 11409.7-1989" rubber antioxidant, vulcanization accelerator ash measurement method ", GB/T 11409.8-1989 "Rubber antioxidant, vulcanization accelerator method for measuring the viscosity of a rotational viscometer method", GB/T 11409.9-2003 "rubber antioxidant, vulcanization Determination hydrochloride promoting agent insoluble content. " this standard is GB/T 11409.1 ~ GB/T 11409.9 integration amendments made.

This standard and GB/T 11409.1 ~ GB/T 11409.9 technical differences.

--- This standard measuring melting point and GB/T 11409.1-1995 difference is. capillary diameter of about 1mm to specifications from 1.2mm ~ 1.4mm, wall thickness of about 0.15mm to 0.2mm ~ 0.3mm (this standard 3.1, GB/T 11409.1-2.5 in 1995), the analysis step, the sample in the capillary constrictions of 2mm ~ 3mm 3mm ~ 6mm high to high, Than forecast by the low melting point 30 °C, and 2 °C/min heating to melting point 25 °C lower than forecast, and 3 °C/min heating, the installation of the capillary when the temperature rose to a melting point lower than the forecast of about 10 °C will be installed before the sample is attached to the capillary temperature Meter on.

--- Determination of the remaining items and GB/T 11409.2 ~ GB/T 11409.9 no technical difference, but have been modified editorial.

The standard proposed by China Petroleum and Chemical Industry Association.

This standard by the National Standardization Technical Committee rubber chemical additives and rubber Technical Committee.
