Abstract

The invention discloses a black masterbatch with high performance, a preparation system device and its preparation method. The masterbatch can be taken as an ultraviolet shielding agent and a black coloring agent, which is widely applied to a polyolefin gas pipeline, a purified water delivering pipeline, conductive plastics, films and cable materials and the like. The characteristics of short production process, raw material negative pressure conveying, sealed type for formulating and feeding, continuously smelting and granulating system enable the raw materials to convey and produce in a sealed system without leakage and fly phenomenon of the carbon black, thereby the good production environment can be guaranteed. According to the invention, the black masterbatch with high performance isprepared by the following raw materials in weight proportion: 20 to 80 parts of polyolefin carrier resin, 20 to 55 parts of carbon black, 0.2 to 2 parts of dispersant, 0.1 to 0.5 parts of processing auxiliary agent and 0.1 to 1.0 parts of anti-oxidant.

Description

technical field [0001] The invention relates to a masterbatch, a preparation system device and a preparation method thereof, more specifically to a high-performance carbon black masterbatch, a preparation system device 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 it can be used as an ultraviolet light shielding agent and black colorant in the plastics industry. Carbon black can be widely used in plastic gas pipelines, water purification pipelines, conductive plastics, plastic films, and cable materials. To achieve good dispersion, it can effectively shield the damage of ultraviolet light to plastic products, so that its service life can reach more than 50 years. In recent years, with the development of the economy and the advancement of technology, the demand for carbon black has increased significantly, and its application fields have als...
