Embodiment Construction

[0020] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] The technical scheme of concrete implementation of the present invention is:

[0022] A kind of dispersion preparation method of high-concentration black color glue, comprises the steps:

[0023] The step of forming a nano-dispersion, the nano-dispersion is prepared by mixing a nano-material, a solvent and a dispersant, and the weight ratio of the nano-material, solvent and dispersant is 1:4:5. Preferably, the nanomaterial in the nanodispersion liquid is ATO. The dispersant in the nano-dispersion liquid includes one or more combinations of the following: silane coupling agent, titanate coupling agent, aluminate coupling agent, aluminum titanate coupling agent, anionic ...

Abstract

The invention discloses a dispersion preparation method of a high-concentration black color adhesive. The preparation method comprises the following steps: forming nano-dispersion liquid, then performing a raw material grinding step, adding carbon black and calcium carbonate into a three-roll grinder, mixing and stirring, adding the ground raw materials into an internal mixer, adding the anti-aging agent, the accelerant, the softener and the styrene-butadiene rubber, slowly adding the nano dispersion liquid, continuously stirring for 45 minutes to obtain the high-dispersity high-concentrationblack color adhesive, and finally pulling and molding by a three-roller machine. The preparation method has the beneficial effects that the nano dispersing agent is introduced so that the dispersing effect is good, and the color adhesive has plasticity requirements of normal calendering, extrusion and other subsequent processing processes.

Description

technical field [0001] The invention relates to the technical field of plastic raw materials, in particular to a method for dispersing and preparing high-concentration black color glue. 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 outsole...
