The modified carbon black comprises 90-98% of carbon black and 2-10% of super carrier according to weight percentage. The preparation method comprises the following steps: conducting surface treatment on the carbon black, and conducting extrusion and granulation through an extruding machine so as to prepare the modified carbon black for rubber. Not only is the problems of large transportation size, large feeding size and flying dust solved, but also the cost barrier is broken through, and high content and granulation of the carbon black become reality; the automatic development of the rubber industry is promoted.
Description
Technical field
The invention belongs to technical field of rubber production, be specifically related to a kind of modified rubber carbon black and preparation method thereof.
Background technology
Rubber is a kind of elastomerics of retractility excellence, but its over-all properties unsatisfactory, produce in rubber item process and usually need add carbon black to improve intensity, wear resistance and resistance to deterioration in sizing material.Rubber grade carbon black has good activity and adsorption rate, and reinforcing effect is good, has very high insulation filling can significantly improve the physicals of sizing material in rubber.At present, rubber grade carbon black is one of main strengthening agent in rubber and plastic industry, but fly upward because its proportion is little, as easy as rolling off a log, stacking volume is large again, add in process for processing link difficulty, industrial automatic charging easily produces flying dust and pollutes production environment.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of modified rubber carbon black, it meets the basic demand of rubber industry automatic feeding system to the female industry of starting material.
Two of object of the present invention there is provided the preparation method of described modified rubber carbon black.
The present invention is achieved through the following technical solutions:
A kind of modified rubber carbon black, comprises and counting by weight percentage:
Carbon black 90% ~ 98%
Super carrier 2% ~ 10%.
Preferably, described carbon black is rubber grade carbon black.
Preferably, described carbon black is the one or more combination thing in N110, N220, N330, N339, N351, N375, N550, N660, N774.
Preferably, described super carrier is the oil material of the certain molecular weight of low melting point, described super carrier be isoprene, cyclopentadiene, 1,3-pentadiene, 1-amylene in acidity, the molecular formula of super carrier is (C
5h
8) n, wherein 7 < n < 15.
Preferably, the fusing point of described super carrier is less than 50 DEG C.
Preferably, the molecular weight of described super carrier is between 500 ~ 1000.More preferably C 5 petroleum resin, it is not only peeled off, and high, the fast viscosity of bonding strength is good, adhesiveproperties stable, melt viscosity is appropriate, good heat resistance, and can all have good consistency with styrene polymer, natural rubber, synthetic rubber and EVA etc. such as SIS, SBS, SEBS, SEPS, also good with natural tackifying resin (terpenes, rosin and derivative thereof) consistency, there is improvement in various degree to the properties of tackiness agent.Because it has fabulous tackifying, in the course of processing, softening, strengthening action can be played, improve extensibility and resistance to flaking.Significantly improve raw sticky, but do not affect the physical property after curing time and sulfuration.Avoid the adhesivity to processor.Help packing material is uniformly distributed.
The method of modified rubber carbon black described in preparation, preparation process is as follows:
A. by proportioning, carbon black and super carrier are prepared the container putting into stirrer to stir, obtained carbon black stock;
B. the carbon black stock crossed through processing of step A is put in forcing machine container;
C. that carbon black stock is pulled out pelletizing again through die head is shaping for screw extrusion press, obtained described modified rubber carbon black.
Preferably, the temperature in the container of described stirrer controls at 40 DEG C ~ 60 DEG C; Or super carrier is first heated to about 50 DEG C, then is placed on high-speed stirring with carbon black.
Preferably, the stir speed (S.S.) in described agitator is 500 ~ 1000 revs/min.
Preferably, the temperature of described forcing machine is 50 DEG C ~ 70 DEG C, and pressure is normal pressure.
The present invention includes the oil material of the certain molecular weight of rubber grade carbon black and low melting point, about 50 DEG C oil materials and carbon black are put together, pass through homogenizer, when high-speed stirring, due to frictional heat between particle and particle, then melting is wrapped on carbon black particle material surface, the inside is not adsorbed onto by silicon-dioxide on the one hand due to super carrier toughness, on the other hand, the styrene polymer such as super carrier and SIS, SBS, SEBS, SEPS, natural rubber, synthetic rubber and EVA etc. have good consistency.Make its toughness and be not adsorbed onto the inside by carbon black, then extruding pelletizing by forcing machine.Modified carbon black in the present invention and preparation technology are breakthroughs in pelletizing of carbon black Technology, meet the basic demand of rubber industry automatic feeding system to the female industry of starting material.And before this, cannot accomplish.Also solve simultaneously transportation volume large, feed intake that volume is large, the problem of flying dust.The invention of super carrier granulating formula and technique, breaches the barrier of cost.Carbon black high-content, granulating is allowed to become a reality.Promote the automation development of rubber industry.
In a word, advantage of the present invention is as follows:
(1), solve application producer weigh and add accessibility problem.
(2) take up space when, solving the large transport of volume problem.
(3), solve when unloading goods, dust is on the impact of factory's respiratory tract and environmental health problem.
(4) integrated mill's automatic feeding system, is solved to the basic problem of starting material master batch, dustlessization.
