Step 1: by 90-110 parts by weight of silicone rubber raw rubber in 43-48 DEG C of temperature of double roller, being kneaded 2-5min, make silicon rubber
The uniform roll banding of glue raw rubber；
Step 2: it is more to sequentially add 30-50 parts by weight white carbon black, 8-15 parts by weight diphenyl silanediol, 1.5-3 parts by weight
Vinyl silicone oil, 1-5 parts by weight polymethylphenylsiloxane non-covalent modification carbon nanotube and the peroxidating of 0.4-1 parts by weight are double
(2,4- dichloro-benzoyl) is kneaded 12-14min, rubber compounding is uniformly obtained rubber compound；
Step 3: rubber compound prepared by step 2 is fitted into mold, and temperature is 175-185 DEG C, the condition of pressure 5-12MPa
Lower hot pressing 9-12min sulfidization molding obtains sulfide film after cooling；In the step 1, the raw-silastic continuously is ethylene methacrylic
Base silicon rubber；
In the step 2, in polymethylphenylsiloxane non-covalent modification carbon nanotube, in polymethylphenylsiloxane
It is compound with π-π effect progress between phenyl ring and carbon nanotube, and prepared by the following method: weigh 0.5-1.5 mass parts carboxylic
Base carbon nano tube ultrasonic disperse obtains the aqueous dispersion liquid of carboxylic carbon nano-tube in distilled water；Weigh 0.5-5.0 mass
Part polymethylphenylsiloxane ultrasonic disperse obtains the dehydrated alcohol dispersion liquid of polymethylphenylsiloxane in dehydrated alcohol；
The dehydrated alcohol dispersant liquid drop of polymethylphenylsiloxane is added in the aqueous dispersion liquid of carboxylic carbon nano-tube, ice-bath ultrasonic
It is taken out after processing 20-40min, suction filtration drying is carried out after sealing and standing 22-26h.
Existing compounding rubber there are the problem of include:
Emulsion dispersion can be such that the fillers such as CNT disperse in rubber matrix more uniformly, usually using demulsifiers such as acid
Realize the co-precipitation of latex particle and CNT, but acid adding or the flocculation of other chemical reagent and subsequent dewatered drying process are easy to make
Filler generation is reunited again, causes low efficiency, the problem that time-consuming and water consumption is big；Mechanical blending method, solution blended process simultaneously
With melt-blending process due to technological problems, there is also some inevitable defects for the rubber composite material of preparation.
Summary of the invention
In order to overcome the shortcomings of prior art, the present invention provides a kind of CNT/IIR composite material and preparation method thereof and mist

The technical solution adopted by the present invention to solve the technical problems is:
A kind of CNT/IIR composite material preparation facilities and preparation method, include the following steps:
S100, centrifugal concentrating butyl latex is added in beaker, and CNT aqueous solution is added in beaker, obtain CNT/
IIRL mixed liquor, and be mixed spare；
S200, CNT/IIRL mixed liquor is ejected on the roller of high temperature open mill by gas phase secondary injection atomizing gun,
When the moisture evaporation of mixed liquor on roller, it is spare that the rubber master batch formed on roller is scraped into collection；
S300, with successively open mill be added 111phr rubber master batch, zinc oxide ZnO, stearic acid SAD, sulphur, ultras
TMTD, DM promotor, RD anti-aging agent, antioxidant 4020 carry out be kneaded carry out rubber master batch plasticate and mixing, complete GO/IIR it is compound
The preparation of material.
Further, 100 mass of mass fraction 42wt% centrifugal concentrating butyl latex point is selected in S100, is slowly added to
5~7min is sufficiently stirred using blender in the 10mg/ml CNT aqueous solution of the half of predetermined volume, stands 2~3min, then plus
3~5min is sufficiently stirred in the 10mg/ml CNT aqueous solution for entering the other half again, completes the preparation of CNT/IIRL mixed liquor.
Further, when carrying out the injection of CNT/IIRL mixed liquor, the pressure of 0.7MPa is acted on into gas phase auxiliary spray
It penetrates on atomizing gun, and the roller temperature of open mill is waited to reach 150 DEG C.
Further, CNT/IIRL mixed liquor to be sprayed in two times or more than twice, injection is spaced in 2~3s,
And when the temperature of roller is down to room temperature, rubber master batch scraped using the scraper plate on roller collect it is spare.

Half 10mg/ml CNT aqueous solution, be sufficiently stirred 5~7min using blender, stand 2~3min, add the other half
10mg/ml CNT aqueous solution, be sufficiently stirred 3~5min again, complete the preparation of CNT/IIRL mixed liquor.
When carrying out the injection of CNT/IIRL mixed liquor, the pressure of 0.7MPa is acted on into gas phase secondary injection atomizing gun
On, and the roller temperature of open mill is waited to reach 150 DEG C.
CNT/IIRL mixed liquor is sprayed in two times or more than twice, injection is spaced in 2~3s, and to roller
Temperature when being down to room temperature, rubber master batch scraped using the scraper plate on roller collect it is spare.
The preparation method is mainly by passing through two kinds of liquid of carbon nanotube (CNT) dispersion liquid and butyl latex (IIRL)
Mechanical stirring is sufficiently formed mixed liquor, and under high pressure vapor atomizing, mixed liquor is first dispersed as fine droplet, completes primary
Broken, fine droplet sputters explosion through high-temperature metal plate surface after, completes second-time breakage, reaches dispersion effect, then drop
By the dry acquisition CNT/IIR rubber master batch of instant dehydration, wherein CNT reaches microcosmic in NR under atomization, sputtering and blast action
Dispersion effect；
Gas phase atomising device can guarantee the uniformity of atomization, reach and be completely dispersed effect, and guarantee to cover on roller
Rubber master batch it is internally dry, while avoid vapor cover formed on instrument it is secondary drop it is attached；
Its simple process is controllable, and scientific in principle is reasonable, and energy consumption and production cost are low, strong operability, disperses more uniform, group
Poly- phenomenon is few, and rolling resistance is small, and use environment is friendly, is easy to be mass produced and promote the use of, and has to environmental protection important positive
Meaning, and prepare to meet material property higher, have higher economic value.
