Abstract
The invention relates to a preparation method of a rubber composite material; differing from traditional methods, the method provided by the invention comprises the following steps of: adding various rubber assistants into water and grinding, then mixing the ground rubber assistants with rubber latex, and directly adding the obtained mixture into a drying device for drying so as to form the rubber composite material, without a gelling step by using acid, a saline solution or analogues. By adopting the rubber composite material prepared by adopting the method disclosed by the invention, the dispersing levels of assistants in the composite material is greatly improved; and vulcanized rubber prepared by adopting the method disclosed by the invention has the advantages of high elasticity and high abrasion resistance.
Description
Technical field
The present invention relates to a kind of preparation method of rubber composite, be specifically related to a kind of method that does not need to prepare rubber composite through the gel step of peracid or salts solution or analogue.
Background technology
It is method the most frequently used in the present industrial production that dry blending prepares rubber composite, all is usually to add reinforcement auxiliary agent, vulcanizing agent and various compounding aid in rubber, processes through dry method is mixing.Mixing this process not only consumes energy but also contaminate environment, difficulty that rubber in mixing process " is eaten powder ", powder flies upward, and environment is produced pollute, also the serious harm health of operators.In addition, because the limitation of dry method calendering process, anti-aging agent and the mineral filler dispersion in rubber matrix can not be very even, local meeting produces serious agglomeration, do not reach the anti-aging and reinforcing effect of ideal, also can sacrifice the valuable characteristic of natural rubber itself simultaneously, as snappiness, high-wearing feature etc.
Except dry blending technology, it also is public known continuously latex and carbon black slurry being joined in the cohesion jar of stirring.This " wet method " technology is generally used for synthetic elastomer, in SBR.Contain a kind of flocculation agent in the cohesion jar, be about salt or the aqueous acid of 2.5-4 as typical pH value.Latex and carbon black slurry mix in the cohesion jar and cohesion is little particle (typical diameter is several millimeters).By vibratory screening apparatus or analogue particle is separated with acid waste liquid then, particle is poured onto in second stirred pot, it is neutral or approaching neutral there it being washed to pH value.And then make these particles experience other vibratory screening apparatus or drying step etc.For the natural and gel synthetic rubber masterbatch, the difference that had proposed this method changes.These methods without exception be all will be through adding the gelation process of acid or salts solution.And add acid or salts solution not only can increase the cost of water treatment, and can cause the corrosion of relevant device.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of preparation method of new rubber composite.
Special feature of the present invention is not need through adding the gelation process of acid or salts solution.At first be that various known rubber ingredients are ground through grinding plant separately or together, make the aqeous suspension or the emulsion of various auxiliary agents, then these aqeous suspensioies or emulsion are joined in the latex, after dispersed with stirring is even, without the gelation process that adds acid or salts solution, directly be added to and carry out drying in the drying plant, make the epoxy glue or the cross-linked rubber of the uncured that contains auxiliary agent.
