Description
Technical field
The present invention relates to a kind of super abrasive carbon black and production technology thereof of mixing easy dispersion.
Background technology
Carbon black be many hydrocarbons (solid-state, liquid, gaseous state) at high temperature, through imperfect combustion cracking produce unformed charcoal.Carbon black specific surface is very wide, and because its production method is different, also difference is very large for the physicochemical properties of carbon black.At present, super abrasion furnace black product quality also quality differs, and the shortcoming of this series of products concentrated expression is exactly that mixing energy consumption is high, difficulties in dispersion, calendering and extruding not easily etc.
Summary of the invention
The object of this invention is to provide a kind of super abrasive carbon black and production technology thereof of mixing easy dispersion.
The technical scheme that the present invention takes:
A super abrasive carbon black for mixing easy dispersion, it is take weight ratio as the carbolineum of 3:2 ~ 9:1 and the mixture of coal tar is feedstock oil, and potash is additive, and natural gas is fuel, adopts super abrasion furnace black oven process production technology to be prepared from; Wherein the mass ratio of feedstock oil and additive is 245:1 ~ 275:1.
The production technology of described super abrasive carbon black, its concrete steps are as follows:
(1) air being compressed to 165 ~ 190Kpa is preheating to 700 ~ 800 DEG C through air preheater, delivers to the distribution plenum of reacting furnace through hot blast pipeline;
(2) described fuel and additive are sent into the combustion chamber of reacting furnace, the hot-air mixed combustion sent with above-mentioned distribution plenum, temperature controls at 1900 ~ 1927 DEG C.Described feedstock oil, after fuel oil preheating device is preheated to 180 ~ 260 DEG C, is sprayed into by the trunnion section of reacting furnace, through atomization, shears, carries out the cracking reaction of 6 ~ 20 microseconds at the conversion zone of reacting furnace, produce carbon black smoke;
(3) described carbon black smoke carries out a chilling at reacting furnace quench zone, more successively through air preheater and fuel oil preheating device, finally carries out secondary chilling, makes flue-gas temperature be down to 260 ~ 290 DEG C;
(4) carbon black smoke after cooling enters main bag hose and collects, and the carbon black of collection delivers to collection cyclone separator through wind pressure fan after micron disintegrator is pulverized;
(5) carbon black of described cyclone collection is through granulator granulation, makes the particle diameter of carbon black particle be 0.5-1.4mm, then drying machine is dry.
The most significant advantage of the present invention is: the present invention take natural gas as fuel; coal tar, carbolineum are mixed into feedstock oil with proper proportion; the feedstock oil adopted is rational in infrastructure; carbon yield is higher, produce the minimum and narrow distribution of carbon black products particle diameter, structure comparison is low; powdery carbon black is obtained after micron disintegrator, comminutor, drying machine; and mature preparation process, be applicable to industrialized production, there is significant economic benefit.
Carbon black products of the present invention (called after LX-LS100) belongs to super abrasion furnace black, has the advantages such as reinforcing property is high, anti-wear performance is fabulous, further improves that super abrasive series carbon black mixing energy consumption is high, difficulties in dispersion, calendering and the shortcoming extruded not easily simultaneously.LX-LS100 carbon black particle dispersion grade point of the present invention can reach about 7 grades, and the N110 carbon black particle belonging to super abrasion furnace black together disperses grade point generally at about 5 grades, as can be seen from above-mentioned separate data, LX-LS100 is higher by about 40% than common super abrasion furnace black dispersion grade point, namely well improves the mixing shortcoming of not easily disperseing of super abrasive series carbon black.
