Abstract

The invention discloses graphene-MBI compound pre-dispersion rubber masterbatch which is composed of, by weight, 55-60% of graphene, 15-35% of 2-mercaptobenzimidazole, 1-4% of vinyl triethoxysilane, 1-2% of dioctyl adipate, 1-2% of triphenyl phosphate, 1-5% of zinc stearate, 7-15% of rubber matrix and 6-14% of industrial white oil, the weight percentage sum of components is 100%, the rubber matrix is composed of main rubber and a processing aid, the main rubber is at least one of EPDM rubber, styrene butadiene rubber, nitrile butadiene rubber, acrylate rubber and chlorohydrine rubber, and the processing aid is paraffin and pentaerythritol stearate. The rubber masterbatch contains two active ingredients including graphene and MBI, the problems of dispersity and dust pollution of graphene and MBI in rubber products can be solved effectively, the rubber masterbatch can promote rubber vulcanization and improve mechanical performance and aging performance when being used for producing vulcanized rubber subsequently.

Description

technical field [0001] The invention relates to the technical field of pre-dispersion and granulation of processing aids, in particular to a graphene-MBI 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 ...
