The invention discloses an oil-filled carbon nanotube emulsion co-precipitation rubber and a preparation method thereof. Its main components are: 100 parts by weight of rubber, 1-40 parts by weight of oil, 1-40 parts by weight of carbon nanotubes, 0.1-5 parts by weight of anti-aging agent; the preparation method is: adding modified carbon nanotube suspension and anti-aging agent Put it into the rubber latex, keep the temperature at 30-60°C and stir for 10-30 minutes; add emulsified oil to the above mixture and stir for 1-10 minutes; add flocculant for flocculation, dehydration and drying to prepare oil-filled carbon nanotube emulsion co-precipitation rubber. The method can overcome the disadvantages of uneven filler dispersion and high energy consumption in the traditional mechanical blending method, and has simple process, low cost and easy popularization. The ratio of oil-filled carbon nanotubes can be adjusted to meet the needs of different users. The emulsion co-precipitation rubber prepared by the method has excellent properties, and its mechanical properties, wear resistance, antistatic and other aspects are greatly improved.
Description
technical field [0001] The invention relates to the technical field of polymer-based nanocomposite materials, in particular to an oil-filled carbon nanotube emulsion coprecipitated rubber and a preparation method thereof. Background technique [0002] Since the discovery of carbon nanotubes (CNTs), there has been a worldwide upsurge in research on CNTs. Based on the excellent mechanical properties of CNTs, it can provide excellent reinforcement and thermal fatigue resistance for the rubber matrix, prolonging its service life; the large aspect ratio of CNTs (greater than 1000) is conducive to improving the tear resistance and wear resistance of rubber sex. This effect cannot be achieved so far including carbon black, white carbon black, organic and inorganic fibers and other nano particles mixed with rubber. Therefore, the research and development of CNTs filled rubber composites is of great significance to the development of new high-performance rubber products. [0003] ...
