TH8855A - Carbon black used to make treads. - Google Patents

Abstract

The invention revealed a carbon black of the type, a strong carbon black with a specific surface nitrogen absorption (N2SA) surface of approximately 65 - 84 m2 / g and the DBP absorption amount of 100. - 150 ml / 100 g, which can be obtained as needed. The relationship shown by formulas 1, 2 and 3 follows.

Claims (1)

1. Carbon black of the type, which is a strong carbon black with a specific surface nitrogen adsorption (N2SA) surface approximately 65 - 84 m2 / g, and the DBP absorption amount is 100 - 150 ml / 100 grams, which will also make as you want. The relationship shown by formulas 1, 2 and 3 is as follows: True Specific Gravity < = 1.9080 - 0.0016 (N2SA) ............. (1) [TINT x Bn]. x 10-2 < _ 55.0 + 0.43 [N2SA] ............. (2) [(Triangle) Dst / Dst] x [N 2 SA / IA] > 0.90 .. ........... (3) where N2SA is the specific surface area for nitorene adsorption, equivalent to m2 / g, TINT is the ability to colorize% Bn, i.e. The blackness in% Dst (nm) (nm) is the difference between the diameter of the two channels, each of which is a channel in frequency, representing 50% of the maximum frequency in the distribution curve of the channel diameter that includes them. Dst is the channel diameter at the highest frequency in the scatter curves of the diameter of the two joined channels, and La is the number of IOD adsorption, expressed in mg / g.
