Abstract

The invention relates to a process for industrialized continuous removal of alkaline impurities in an SEBS rubber liquid or an SBS rubber liquid. An emulsifying machine for emulsifying deionized water with a rubber liquid and an emulsifying machine for emulsifying neodecanoic acid with the rubber liquid are in series operation, and thereafter, a high-speed centrifugal separator is used for separating the emulsified water and the emulsified rubber liquid, moreover, the high-speed centrifugal separator operates in a continuous feeding mode, and lithium ions and other alkaline impurities in the SEBS rubber liquid or the SBS rubber liquid are continuously and effectively removed; the process is simple and efficient, and is suitable for industrialized production for removal of the alkaline impurities in the SEBS rubber liquid or the SBS rubber liquid.

Description

technical field

[0001] The invention belongs to the field of preparation technology of macromolecule SEBS or SBS materials, and in particular relates to a technology for industrialized continuous removal of alkaline impurities in SEBS glue or SBS glue. Background technique

[0002] Baling brand SEBS products are developed using technology with independent intellectual property rights, which fills the gap in the domestic rubber industry. SEBS products are products after hydrogenation of styrene-butadiene block copolymers, which have excellent aging resistance and high and low temperature performance, and are widely used in wire and cable, auto parts, toys, adhesives and polymer modification, etc. multiple fields. The composite antioxidant system used in SEBS products has good thermal oxidation resistance and weather resistance, which includes a phosphite antioxidant and a phenolic antioxidant. Since the industrial production of SEBS in 2006, 2.6.4, 6.2.6, TNP, etc. have bee...
