Easy to disperse in the matrix. For example, metal soap compounds and other active ingredients have a significant wetting effect on white carbon black, which can reduce the polarity of white carbon black and improve its emulsifying and dispersing effect at the interface with rubber.Phase interface adhesion: The polarity of fatty acid esters is between that of fatty acid metal salts and non-polar rubber, acting as a phase interface adhesive, improving the interaction between fatty acid metal salts and rubber, and stabilizing the dispersion of strongly polar substances in non-polar rubber.Surface modification: Treating white carbon black with coupling agents, such as silane coupling agents, can react with hydroxyl groups on the surface of white carbon black, improve the compatibility between white carbon black and the matrix, and enhance dispersibility.Coating and graft polymerization: By coating a layer of polymer or grafting specific monomers on the surface of white carbon black, a polymer layer with specific functions is formed to improve dispersibility while endowing white carbon black with new properties.Electrostatic repulsion and steric hindrance: Ionic dispersants adsorb onto the surface of white carbon black through electrostatic interactions, generating electrostatic repulsion; Non ionic dispersants prevent particle aggregation through steric hindrance effect. Polymer dispersants provide both electrostatic repulsion and steric hindrance, resulting in a more significant dispersion effect on white carbon black.Application effect of white carbon black dispersantThe use of white carbon black dispersant can significantly improve the dispersion effect of white carbon black, specifically manifested as:Reduce energy consumption: During the mixing process, the use of white carbon black dispersant can reduce energy consumption, increase extrusion speed, and lower Mooney viscosity.Improving dispersion: significantly reducing the agglomeration of white carbon black, increasing the contact area between white carbon black and rubber, and enhancing the reinforcement effect.Improving physical properties: Adding white carbon black dispersant to rubber can improve its physical properties, such as tensile strength, tear strength, etc.Environmentally friendly and efficient: In the future, white carbon black dispersants will develop towards environmental protection, high efficiency, and low toxicity, and expand to fields such as new energy and electronic information.
