A kind of oil-filled carbon nanotube binary emulsion coprecipitation rubber and preparation method thereof

Abstract

The invention discloses an oil-filled carbon nanotube binary emulsion co-precipitation 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, anti-aging 0.1-5 parts by weight of agent; the preparation method is: adding modified carbon nanotubes, emulsified oil, and anti-aging agent into the emulsion composed of two kinds of rubber latex, keeping the temperature at 30-60°C and stirring for 1-30 minutes; Adding flocculant to the mixture, the oil-filled carbon nanotube binary emulsion co-precipitated rubber was prepared by flocculation, dehydration and drying. The method can overcome the shortcomings of non-uniform filler dispersion and high energy consumption in the preparation of binary rubber nanocomposites by the traditional mechanical blending method, and has simple process, low cost and easy popularization. In the composite material prepared by the method, the carbon nanotubes are uniformly dispersed in the rubber matrix and play an effective reinforcing role. The emulsion co-precipitation rubber prepared by this method has greatly improved mechanical properties, wear resistance, antistatic and the like.
