Modified carbon black composite material and its preparation method and application

Abstract

The invention discloses a modified carbon black composite material as well as a preparation method and application thereof. The modified carbon black composite material is prepared from 1 weight percent to 90 weight percent of carbon black and 10 weight percent to 20 weight percent of an inorganic nano-material, wherein the inorganic nano-material is tightly laminated to the surface of the carbonblack and / or embedded into the carbon black. According to the modified carbon black composite material disclosed by the invention, the inorganic nano-material is combined with the carbon black, the roughness of the surface of the carbon black is increased, and the high-energy active point of the surface of the carbon black is increased, so that the reinforcing performance of the modified carbon black composite material in a rubber material is improved; the dosage of the carbon black is reduced in a preparation process of the rubber material, and the production cost is reduced.

Problems solved by technology

[0002] Inorganic nanomaterials have a certain reinforcing effect in the rubber matrix due to their unique nano-size effect and high surface activity, but due to the strong agglomeration between the nanomaterials and the compatibility with the interface of rubber macromolecules Due to poor performance and other reasons, the dispersion performance of inorganic nanomaterials in the rubber matrix is ​​not good, which greatly affects the performance of its reinforcing performance.

In order to solve the above problems, people are used to modifying the surface of inorganic nanomaterials. Many scientific research institutes have made related attempts, but the method of surface modification often leads to a great increase in production costs, and the modification effect may not be good. Therefore, it affects the potential value of inorganic nanomaterials.

The traditional reinforcing material carbon black, which has been widely used in the rubber industry, does not have the above problems, but carbon black also has its own shortcomings, that is, the basic raw materials for the production of carbon black are, after all, increasingly precious strategic energy sources such as petroleum, coal, and natural gas. materials, which forces people to develop new reinforcing materials, reduce the amount of carbon black production, get rid of or reduce the dependence on carbon black
