Abstract

The invention provides highly dispersible black colorant rubber. The highly dispersible black colorant rubber comprises, by mass, 30% of butadiene-styrene rubber, 18.5% of calcium carbonate, 8% of softening oil, 42% of carbon black, 1% of an anti-aging agent and 0.5% of a slipping agent. The invention also provides a preparation method of the highly dispersible black colorant rubber. The preparation method can ensure that the carbon black and auxiliary agents in the rubber can be uniformly supported by the carrier rubber, keep good color development physical properties and a dispersion degree of the black rubber, and satisfy colorant rubber plasticity demands in later processes such as normal rolling and extrusion.

Description

technical field [0001] The invention relates to a high-dispersion type black color glue and a preparation method thereof. Background technique [0002] Black color glue is a coloring pigment widely used in rubber products. It is used in rubber foam, shoe outsoles, seals, tires, rubber parts, etc. Carbon black, the raw material for the production of black color glue, is an important chemical material. It is a black powdery substance obtained by gas-phase combustion or pyrolysis of hydrocarbons under strictly controlled process conditions. The main component is elemental carbon, and it also contains a small amount Oxygen, hydrogen and sulfur etc. The tinting strength of the black color glue depends on the particle size of the carbon black, the toner concentration of the color glue, and the mixing process and dispersion process. For shoe factories, when using black color glue as a colorant to produce shoe outsoles, if the color glue is not well dispersed, the produced rubber ...
