SU840075A1 - Plastifier based on oil of petroleum hydrocracking - Google Patents

Description

one

This invention relates to a rubber industry, in particular to a plasticizer based on oil hydrocracking base oil.

Known plasticizer on the base of new base oil hydrocracking oil. for rubber mixtures of low-unsaturated chain-chain elastomers, nagfimer (Stabol-18) 1.

However, the rubber compound obtained is. using these plasticizers, have unsatisfactory technological properties, and rubber from them have low physical and mechanical properties.

The purpose of the invention is to improve the technological properties of mixtures and improve the physico-mechanical properties of rubber from them.

The goal is achieved by the fact that the plasticizer based on petroleum hydrocracking base oil for rubber mixtures of low-chained carbon chain elastomers further contains diisooctyl adipate and polyethylsiloxane in the following ratio of components, wt.%: Base oil hydrocracking oil (BNG) 1-98

Diisooctyl adipate (DOA) 1-98

Polyethylsiloxane (PES) 1-98
