Abstract

The invention discloses a low-viscosity rubber oil preparation method, and belongs to the technical field of petrochemical industry. According to the present invention, naphthenic SZ36-1 crude oil isused as a raw material, has low viscosity, and contains an appropriate amount of the aromatic hydrocarbon compound with good solubility with rubber, such that the rubber prepared by using the naphthenic SZ36-1 crude oil as the raw material has good compatibility with the rubber; proteins have good foaming ability in the rubber oil, and micro-nano gas bubbles are introduced into the rubber oil, such that the acting force between different oil molecules in the hydrorefined oil and the acting force between other complex organic substances in the hydrorefined oil are weakened; and the rubber oil prepared by using the glycidyl ester epoxy resin as the raw material can enhance the flexibility of the rubber, and after the glycidyl ester epoxy resin and the mixed liquid containing the protein andthe hydrorefined oil are subjected to blending heating stirring, the active group on the surface of the glycidyl ester epoxy resin and the active group on the surface of the mixed liquid generate thehydrogen bond adsorption force, such that the glycidyl ester epoxy resin and the mixture are integrally combined so as to achieve broad application prospects.

Description

technical field [0001] The invention discloses a preparation method of low-viscosity rubber oil, which belongs to the technical field of petrochemical industry. Background technique [0002] In order to improve the properties of rubber such as elasticity, flexibility, ease of processing, and ease of mixing, it is usually necessary to add specific rubber oil to achieve the purpose. In the actual use of rubber oil, because of different uses and different industries, there are many specific differences in the physical and chemical properties of rubber oil, so many names and brands are derived. For example, according to the differences in the molecular structure and composition of mineral oil itself, it can be divided into paraffin-based rubber oil, naphthenic rubber oil, aromatic-based rubber oil, etc.; oil, rubber softener, etc. [0003] At present, aromatic hydrocarbon rubber oil is the most used in the tire industry, because aromatic hydrocarbons have the best compatibilit...
