Problems solved by technology
[0004] The purpose of the present invention is to overcome in the preparation technology of existing carbon black-filled styrene-butadiene rubber masterbatch, owing to adding surfactant as carbon black dispersant, the rubber modulus stress and strength reduction that the surfactant that remains in rubber causes Insufficiency and surfactant lead to the deficiency of waste water treatment cost increase, provide a kind of preparation method of carbon black-filled styrene-butadiene rubber master batch that is suitable for non-contact pollution without adding surfactant

Abstract
The invention belongs to the field of preparation of a rubber master batch and discloses a preparation method of a carbon-black-containing butadiene styrene rubber master batch. The preparation method includes following steps: preparing raw materials including a dry rubber, carbon black, water, operation oil, a wrapping agent, and a flocculant with a weight ratio being 100:(40-100):(1500-3000):(0-30):(1-5):(1-5) according to the weight of a latex; preparing a carbon black suspension; mixing the latex with the carbon black and performing a thermal treatment; carrying out a coagulation process; and carrying out a post process to a coagulated product. The preparation method of the carbon-black-containing butadiene styrene rubber master batch is free of addition of surfactants and is simple, stable and reliable in processes. A product is free of a contact polluting property and is stable when being stored. A vulcanized robber of the product is excellent in physical and mechanical performances and particularly is excellent in a dynamic mechanical performance.
Description
technical field [0001] The invention belongs to the field of rubber masterbatch preparation, and in particular relates to a preparation method of carbon black-filled styrene-butadiene rubber masterbatch. Background technique [0002] Carbon black-filled rubber masterbatch, also known as carbon black-filled rubber, is a premix of rubber and carbon black. It can be divided into two categories according to the preparation method: one is the rubber latex / carbon black blending method, That is, the rubber / carbon black premix (carbon black masterbatch) prepared by using rubber latex and carbon black as raw materials; Rubber masterbatch. Compared with the latter, the former disperses carbon black in water to make carbon black slurry, and then mixes it with latex to form a rubber / carbon black mixture, which is the main method for preparing carbon black masterbatch, and there is no carbon black flying during the preparation process , Carbon black is more uniformly dispersed in the r...
