Abstract

The invention discloses a graphene-ZDBC composite pre-dispersed rubber master batch which includes, by weight, 40-48% of graphene, 25-35% of zinc dibutyldithiocarbamate, 3-7% of a coupling agent, 1-3% of saturated fatty acid, 1-3% of fatty acid alcohol ester, 1-3% of triethanolamine, 1-3% of zinc stearate, 6-14% of a rubber substrate, and 6-16% of paraffin oil, the sum of weight percentages of the components is 100%. The rubber master batch contains two active components, graphene and zinc dibutyldithiocarbamate (ZDBC), and has synergistic acceleration effect. When being used for producing vulcanized rubber in subsequent steps, the rubber master batch can promote vulcanization of rubber and improve tensile strength, tear strength, wear resistance and aging resistance of rubber. The graphene-ZDBC composite pre-dispersed rubber master batch has low Mooney viscosity and maintains the original activities of the graphene and ZDBC, so that the graphene and ZDBC are uniformly dispersed in the rubber master batch.

Description

technical field [0001] The invention relates to the technical field of pre-dispersion and granulation of processing aids, in particular to a graphene-ZDBC composite pre-dispersion masterbatch and a preparation method thereof. Background technique [0002] Graphene is a new type of carbon material in which carbon atoms are closely packed in a two-dimensional plane to form a two-dimensional honeycomb lattice. Graphene is currently the thinnest but hardest nanomaterial in the world. It is almost completely transparent and only absorbs 2.3% of light; its thermal conductivity is 5300W / m K, much higher than that of diamond and carbon nanotubes; at room temperature, Its electron mobility reaches 15000cm 2 / V·s, much higher than that of carbon nanotubes and silicon crystals; its resistivity is about 10 -6 Ω·cm, excellent electrical conductivity, equivalent to some metals; it has a high specific surface area, the limit value can reach 2630m 2 / g. Due to the unique characteristics...
