Problems solved by technology

However, the coupling agent does not completely solve all the problems in the application, and the production process of the silane coupling agent will produce a large amount of high-salt organic wastewater, which will seriously pollute the environment and be relatively expensive.

Abstract

The invention provides application of zinc isoocatanoate in reduction on agglomeration of white carbon black. According to research, the inventor discovers that the polarity of a silanol group on the surface of white carbon black can be reduced by zinc isoocatanoate so as to play a role in dispersing white carbon black. Under the support of the function, zinc isoocatanoate can be used in the application field of multiple white carbon blacks. The invention also provides a white carbon black dispersing agent containing zinc isoocatanoate and a preparation method thereof. The method is simple, free of pollution, energy-saving and environment-friendly; the obtained dispersing agent has functions of physical dispersion and chemical dispersion, and is suitable for dispersing sizing materials with high filling amount of white carbon black, so that the dispersibility of the white carbon black can be improved, the processing performance of the sizing material also can be improved, the mixing time is shortened, the smoothness and dispersion uniformity of the sizing material is increased, the flowability of the sizing material in the processing and mixing stage is increased, and the Mooney viscosity is reduced; moreover, the white carbon black dispersing agent has a strengthening effect, and the mechanical property of vulcanized rubber is improved.

Description

technical field [0001] The invention relates to a white carbon black dispersant for rubber and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] In order to improve the mechanical strength, wear resistance and wet skid resistance of the tire, it is necessary to add a large amount of filling and reinforcing agent silica to the rubber. Due to the presence of a large number of silanol groups on the surface of silica, these groups are easy to aggregate and agglomerate, and it is difficult to disperse uniformly during tire processing, and the Mooney viscosity of the compound is easy to rebound, thereby affecting the mechanical properties. Therefore, the technical form of adding a silica dispersant or an active agent during rubber mixing can improve the chemical properties of the silanol groups on the surface of silica, increase the surface activity of silica, and achieve good dispersion in rubber, thereby improving Or...
