Abstract
The invention relates to environment-friendly reinforced rubber and a preparation method of the environment-friendly reinforced rubber. The environment-friendly reinforced rubber contains the following components in parts by weight: 100 parts of nitrile rubber, 51-53 parts of waste tire pyrolysis carbon black (PCB), 3.1-3.5 parts of zinc oxide, 0.8-0.9 part of stearic acid, 1.1-1.3 parts of accelerator, 1 .8-1.9 parts of sulfur and 0.1-0.3 part of fluorine-containing surfactant. Raw nitrile rubber after plastication is placed in an open mill; after roller banding, the stearic acid, the zinc oxide, the accelerator and the PCB are added (spraying fluorine-containing surfactant and conducting stirring to uniform); and finally the sulfur is added and the open mill thins and dredges for 6 times, therefore the gross nitrile rubber is obtained. The environment-friendly reinforced rubber can solve the problems that the elementary particles of the PCB are smaller than that of common commercialization black carbon and aggregation is caused due to close arrangement; in addition, the PCB is effectively and uniformly dispersed, the mechanical strength of the gross nitrile rubber is improved, and a hydrophobic, oleophobic and smooth surface is obtained, therefore the environment-friendly reinforced rubber is incomparable to the common commercialization black carbon and the comprehensive property is improved obviously.
Description
Technical field
The present invention relates to the rubber preparation field, especially relate to a kind of environment-friendly type Reinforced Rubber and preparation method thereof.
Background technology
Carbon black is the most important reinforced filling of rubber industry, is difficult to replace in the usefulness that rubber strengthens the field as traditional practical filler.But preparation carbon black not only consumes energy and raw material but also contaminate environment.The damaged tire cracking technique that low-carbon circular economy expedites the emergence of, one of its main split product is a carbon black, is used for rubber item and can saves the energy, reduces production costs simultaneously.So rubber industry utilizes damaged tire cracking black carbon (PCB) to become the concern of industry.Existing now scholar studies basic structure and the modification technology of PCB, but the systematic Study how rubber item utilizes PCB still seldom, therefore demands researching and solving rubber item employing PCB enhanced production technology urgently.Because PCB ash oontent height, the natural characteristics that particle diameter is little, make its reinforced effects not as high-quality carbon black N330,, make it to bring into play the little strong point of particle diameter so study intensively PCB Reinforced Rubber technology, overcome clustering phenomena again, dwindle the gap with high-quality carbon black N330 reinforced effects, even some performance surmounts to some extent as far as possible, for example obtain hydrophobic, hate oil, level and smooth surface obviously is a challenging gordian technique.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of PCB of making to be uniformly dispersed for the defective that overcomes above-mentioned prior art existence, thereby effectively improve the mechanical property of rubber unvulcanizate, obtain hydrophobic simultaneously, hate oil, surface smoothing, environment-friendly type Reinforced Rubber that over-all properties is high and preparation method thereof.
Purpose of the present invention can be achieved through the following technical solutions:

A kind of preparation method of environment-friendly type Reinforced Rubber is characterized in that, this method may further comprise the steps:
(1) get the raw materials ready according to following component and weight part content:
(2) will hope the paracril rubber after the refining put into mill, the damaged tire cracking black carbon that adds stearic acid, zinc oxide, promotor successively and sprayed tensio-active agent and stirred behind the bag roller, add sulphur at last, sheet down after the mill thin-pass 6 times promptly obtains the paracril rubber unvulcanizate.
Compared with prior art, advantage of the present invention is to add to have high surface, high heat-resistant stability, high chemical stability, the lipophobic again fluorochemical surfactant of hydrophobic, overcome PCB particle accumulation phenomenon, PCB can effectively be uniformly dispersed, improve the physical strength of paracril rubber unvulcanizate, obtain hydrophobic simultaneously, hate oil, level and smooth surface, paracril rubber unvulcanizate over-all properties is obviously improved, especially hydrophobicity performance improves and low coefficient of friction surfaces can suppress friction process and produces the electrostatic possibility, and is most important to mining Plastic-sheathed Cable.Also can be widely used in other rubber item higher, realize that PCB is used for the purpose of important rubber item, renewable resource are appreciated, and environmental protection be energy-conservation again performance requriements.
Embodiment
The present invention is described in detail below in conjunction with specific embodiment.
Studies show that, the PCB ultimate particle is spherical, commercialization carbon black particle commonly used is littler, arrange tightr, Van der Waals force between the particle causes the particle agglomeration size to be about 10 μ m, obvious size (being about 2 μ m), particle agglomeration distribution of sizes broad simultaneously greater than convenience goods carbon black N774 aggregate.The analysis showed that C content is more than 85% in the PCB main chemical compositions, also contain O, Si, three kinds of non-metallic elements of S and Al, Ni, four kinds of metallic elements of Cu, Zn, for the PCB particle that is uniformly dispersed, it is little to bring into play its particle diameter, the effect of more effective Reinforced Rubber.Consider from being convenient to tissue production, adopt and add table and the method for promoting agent, the present invention adopts fluorochemical surfactant, to solve the clustering phenomena of PCB ultimate particle, make it to be dispersed in the rubber unvulcanizate, reach the purpose of the mechanical property of effective raising paracril rubber unvulcanizate, obtain hydrophobic simultaneously, hate oil, the effect of surface smoothing, paracril rubber unvulcanizate over-all properties is obviously improved, thereby enter the row of important rubber item, broadened application scope.
