Description

Technical field [0001] The invention relates to a preparation system device of a master batch and a preparation method thereof, and more specifically to a preparation system device of a carbon black master batch and a preparation method thereof. Background technique [0002] Carbon black is an important functional filler. It is mainly used as a reinforcing filler in the rubber industry and as an ultraviolet shielding agent and black colorant in the plastic industry. Carbon black can be widely used in plastic gas pipelines, water purification pipelines, conductive plastics, plastic films, and cable materials. For example, carbon black with a content of more than 2.5% and original ecological particles of 5-20nm is used in plastic products. Achieve good dispersion, can effectively shield the damage of ultraviolet light to plastic products, and make its service life more than 50 years. In recent years, with economic development and technological progress, the demand for carbon black...
