A kind of oil-filled carbon nanotube solution co-coagulation rubber and preparation method thereof

Abstract

The invention discloses an oil-filled carbon nanotube solution co-coagulation rubber and a preparation method thereof. The main components are: 100 parts by weight of rubber, 1-80 parts by weight of oil, 1-80 parts by weight of carbon nanotubes, and 0.1 parts by weight of anti-aging agent -5 parts by weight, 0.1-5 parts by weight of coupling agent; the preparation method is: add modified carbon nanotubes, oil, coupling agent and anti-aging agent to the rubber solution, keep the temperature at 30-60°C and stir for 1-30 minutes ; Incorporate water vapor into the above mixture, and use a distillation separation device to distill and recover the solvent oil; after drying, the oil-filled carbon nanotube solution co-coagulated rubber is prepared. 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. In the prepared composite material, the carbon nanotubes are uniformly dispersed in the rubber matrix and play an effective reinforcing role. 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 solution co-coagulated rubber and a preparation method thereof. Background technique [0002] Rubber is an important strategic material. Because of its special high elasticity, it is used in various fields of the national economy. However, the biggest disadvantage of rubber is its low strength, and it must be added with a reinforcing agent to be useful. For a long time, carbon black and silica have dominated as reinforcing agents for rubber. However, in addition to serious pollution, carbon black also depends on petroleum energy materials, which is expensive. However, silica is not only not ideal for reinforcing effect, but also expensive. Therefore, finding a rubber reinforcing material with low price, environmental protection and pollution-free and excellent reinforcing effect has always been the focus of research b...
