Description
Technical Field
The invention relates to the technical field of carbon black master batch production, in particular to a carbon black master batch with good dispersibility and wide universality, a preparation system device and a preparation method thereof.
Background
In the modified plastic industry, carbon black is often used as a black colorant and a uv-screening agent due to its good chemical stability, high coloring power, and low cost. The carbon black has primary particle size of 5-300nm, is a very fine and granular pigment, and has specific surface area up to 1200m2And/g, the surface activity is large and the agglomeration is easy. As a colorant, the coloring ability of carbon black is directly related to the degree of dispersion of carbon black in a colored object and particle diameter, and carbon black can reach most of full-color deep black only in the case of complete dispersion; at the same time, it is necessary to protect workers, machinery and the environment from the serious attack of dust during the processing of very fine carbon blacks. Therefore, the preparation of the carbon black into the master batch is very key for solving the problem of the dispersibility of the superfine carbon black, improving the coloring capacity of the carbon black, solving the problem of dust pollution and improving the production efficiency.
The prior process for preparing the carbon black master batch mainly comprises the following 3 steps:
1) CN101701100A adopts a high-speed mixer and a double-screw extruder equipment process. The matrix resin, the carbon black, the dispersing agent and other additives are stirred and mixed at a high speed through a high-speed mixer, the mixture forms agglomerated small particles to a certain degree, and then the agglomerated small particle agglomerates are subjected to melt plasticization, dispersion and extrusion granulation through a double-screw extruder, so that the method has the advantages of simple equipment and low investment; has the disadvantages that carbon black dust is easy to fly under the high-speed stirring of a high-speed mixer, the environmental pollution is large, and the content of the carbon black prepared by the process method is not more than 30 percent.
2) CN102532666, CN102040814A and the like adopt equipment processes such as a high-speed mixer, an internal mixer and a single-screw extruder. And after the resin, the carbon black and the functional host machine are uniformly plasticized in the internal mixer, feeding the internally mixed agglomerate into a single-screw extruder through a forced feeder for extrusion granulation. The method has the greatest advantages that the method can produce the carbon black master batch with the carbon black content of 55 percent; the method has the disadvantages that the working mode of the internal mixer is intermittent, so that the production process of each batch is unstable, and the quality difference of internal mixing products is large; secondly, the carbon black is easy to cause dust pollution in the production mode; finally, the production efficiency is low in the production mode.
3) CN102206372A, etc. by using a scale and a double-rotor continuous kneader, etc., a resin, a dispersant, carbon black, etc. are melted, plasticized and kneaded by the double-rotor continuous kneading, and then cooled and pelletized to prepare carbon black master batches, which has the following disadvantages: 1) the rotors of the double-rotor continuous mixing equipment are generally short, materials are mixed through the high-speed rotating rotors in the mixing chamber, the materials are extruded through the rotors after being mixed to a certain degree, the controllability of the mixing time of the materials in the mixing chamber is not high, when the content of carbon black exceeds 45%, the materials are extremely easy to cause excessive mixing or insufficient mixing degree, the production is very abnormal, and the product qualified rate is low; 2) secondly, the equipment is difficult to operate, when high-content carbon black master batches are prepared, a stable molten pool is formed in a mixing chamber through resin, then the content of carbon black is slowly added from low to high to ensure the stable and continuous production of the mixing temperature field, taking the master batches with the carbon black content of 50% as an example, the adding time of the whole carbon black body content gradually exceeds 15min from low to high, and the product produced in at least 15min is an unqualified product.
4) In the prior art, the black master batch for preparing carbon is added with a dispersant such as stearate or wax to ensure that carbon black is better dispersed in matrix resin, but the prepared master batch contains stearate or wax which is easy to separate out, so that the mechanical property and the aging resistance of the product are reduced, peculiar smell is easy to generate, and the application range of the carbon black master batch is greatly limited.

TABLE 2
From the comparison of example 5 with examples 11-12 and the comparison of example 7 with example 13, it can be seen that the carbon black masterbatch made by selecting polyethylene consisting of 10-70 parts by weight of low density polyethylene and 0-35 parts by weight of linear low density polyethylene according to the present invention has a higher melt index and better processing flowability than the carbon black masterbatch made by polyethylene other than the above combination (e.g., polyethylene consisting of high density polyethylene, low density polyethylene and/or linear low density polyethylene).
As can be seen from examples 1-13, the carbon black produced by the apparatus and method of the present invention is high in content and continuous and stable in production. As can be seen from the above examples 5-10, the carbon black master batch of the present invention, which is prepared by using polyethylene comprising 10-70 parts by weight of low density polyethylene and 0-35 parts by weight of linear low density polyethylene, has high carbon black content and good aging resistance, odor and dispersibility; particularly, the polyethylene consisting of 10 to 35 weight portions of low-density polyethylene and 25 to 35 weight portions of linear low-density polyethylene is selected, and the carbon black master batch has higher carbon black content.
The carbon black master batch prepared by the device has the carbon black content higher than 29 percent and further higher than 50 percent, and has continuous production and uniform production quality.
