Description
Technical field
The present invention relates to a kind of dispersant, and in particular to a kind of high-performance environment-friendly rubber disperse agent.
Background technology
Dispersant is to make one of a kind of indispensable dispensing in rubber, commercially play always it is stable and
And important role, dispersant are multiple-effect rubber compounding processing aids, its performance is mainly manifested in the dispersion effect of strength, can
To accelerate and improve the scattered of carbon black, white carbon and other fillers, shorten mixing cycle, improve melting efficiency, this dispersant
Added in rubber compounding, vulcanizing system do not occurred to disturb and the Mooney viscosity of sizing material can be reduced, can also prevent sizing material incipient scorch,
Be advantageous to increase the mobility of sizing material；This dispersant has given full play to fiting effect by various types of materials, adequately achieves rubber and matches somebody with somebody
The strength physical property and requirement just designed；
For now, whether domestic or external, rubber disperse agent uses by pluck more（Such as：Ox, sheep）Refine
The tallow fatty acid got carries out by direct and zinc oxide or in a kettle height with zinc solution indirectly as main material
Temperature reaction, then scrubbed drying process, then through being granulated or cutting into slices to obtain the tallow fatty acid zinc soap class of high relative zinc content
Rubber disperse agent finished product；
It is well known that tallow fatty acid smell is irritant, operating environment can be caused to be difficult to the odor contamination removed, to the person
Certain inadaptability can be caused；Secondly, the internal organ of the most cattle and sheep of tallow fatty acid form through refining, wherein containing a large amount of natural
Trans-fatty acid, this is harmful, and it can increase LDL-C, increases heart disease and obesity
Occurrence probability；Finally, in terms of environmental problem, the further investigation to Zn content in sizing material is more and more, these problems it is main
According to being a heavy metal species for zinc, there is genotoxic potential to aquatic organism, rubber produces during normal use by wearing away
Raw shoddy spreads to substantial amounts of zinc in environment, and particularly EU Committee's instruction divides zinc oxide into N class nuisances
Matter（I.e. to environmentally hazardous substance）, this problem increasingly caused the attention of rubber, rubber chemicals circle scientific and technical personnel, therefore
The development trend of rubber industry is to reduce the Zn content of rubber as far as possible, is exactly in design for rubber formulation from source
When to use low zinc or the compounding ingredient without Zn content as far as possible；
In addition, dodecyl benzene sulfonate has quite varied application neck as a kind of conventional detergent, emulsifying dispersant
Domain, but the shortcomings that dodecyl benzene sulfonate generally existing is serious, they are more sensitive to hard water, they are filled in sewage disposal
Biodegradation rate in putting is very low and degraded to water not exclusively so that cause serious pollution to environment, to solve this
A kind of one problem, it is necessary to but also green material that effect on environment as far as possible small good with not only dispersive property.
In summary, it is a kind of very urgent trend to research and develop a kind of new environmentally friendly dispersant of green, more meets country
The strategy of sustainable development.The novel high-performance environmental protection dispersant of the present invention is exactly to be researched and developed under this technical background.
The content of the invention
