Abstract

A zinc oxide pre-dispersion master colloidal particle and a preparation method thereof relate to a rubber assistant. A prescription of the zinc oxide pre-dispersion master colloidal particle is composed of the following components by mass: 80 parts of zinc oxide, 16 parts of base material; 1 part of stearic acid and 3 parts of white oil. The used base material is composed of ethylene-propylene-diene monomer (EPDM), ethylene-vinyl acetate copolymer (EVA) and ethylene-octene copolymer (POE), the type of the used EPDM is 4045, content of vinyl acetate in EVA is 30%, and the type of POE is 8180. The zinc oxide pre-dispersion master colloidal particle is obtained by evenly dispersing zinc oxide powder into a carrier and conducting pelleting. The zinc oxide pre-dispersion master colloidal particle of the base material is suitable for being applied to tread rubber prescription to resolve the problems of dust, mixing rate and the like in the mixing process of the tread rubber.

Description

technical field [0001] The invention relates to a rubber additive, in particular to a zinc oxide pre-dispersed masterbatch and a preparation method thereof. Background technique [0002] Pre-dispersed masterbatch is a physical mixture of a single substance or several substances and a carrier. This modified form or modified form of predispersed masterbatches is made to optimize the material for its specific application. [0003] Additive predispersed masterbatches can solve many problems, including: [0004] ①Prevent workers from direct contact with dangerous goods; [0005] ② Simplify the processing technology, facilitate mixing, facilitate work, save time and energy, and thus help reduce production costs. [0006] In the rubber industry, the demand for pre-dispersed masterbatches is increasing, and various forms of varieties have been developed one after another. In addition to improving hygiene and safety, pre-dispersed masterbatches also have economic advantages. For ...
