Abstract

The invention discloses a preparation method of a wet-process zinc oxide pre-dispersion master batch, which comprises the following steps: dispersing zinc oxide, an inorganic carrier, a modifier and aprocessing aid in a first part of water to obtain mixed slurry A; uniformly stirring a rubber emulsion, a stabilizer and a second part of water to obtain a rubber liquid B; mixing and flocculating the mixed slurry A and the rubber liquid B to obtain a zinc oxide and rubber compound; and drying and granulating the zinc oxide and rubber compound to obtain the zinc oxide pre-dispersed master batch.Zinc oxide in the prepared zinc oxide pre-dispersion master batch is better in dispersity, smaller in particle size and higher in activity. In the formula, the zinc oxide pre-dispersed master batch isequivalent or reduced by 40% to replace indirect zinc oxide or ZnO-80, the Mooney viscosity, the scorch time and the vulcanization rate of the unvulcanized rubber are basically kept consistent; physical and mechanical properties of vulcanized rubber are basically kept consistent before and after aging.

Description

technical field [0001] The invention relates to the field of rubber additives, in particular to a preparation method of wet-process zinc oxide pre-dispersed master batches. Background technique [0002] Pre-dispersed rubber additive masterbatch is a widely used rubber additive product. The pre-dispersed rubber additive masterbatch successfully turns the powder into a solid product coated with polymers. The pre-dispersed rubber additive masterbatch is mainly a pretreatment for rubber additives that are difficult to disperse well in the rubber body. The product obtained by the method is applied in rubber products, which can not only improve the dispersion uniformity of rubber additives and thus improve the quality of rubber products, but also effectively reduce energy consumption and improve environmental dust pollution. The method of masterbatching pre-dispersed rubber additives is divided into dry granulation and wet granulation. At present, the processing methods of powde...
