Abstract

The invention provides a modified rubber oil additive, a preparation method and modified rubber oil thereof. The modified rubber oil additive is prepared from, by mass, 5-10 parts of polyisobutene, 5-10 parts of alkanes C15-C18, 3-5 parts of a nanometer material and 5-10 parts of an antioxidant. When the rubber oil is modified by the modified rubber oil additive, fluid viscosity of the rubber oil is enhanced, and the movement viscosity number is higher than 31 mm<2> / s under the temperature of 40 DEG C; the movement viscosity number is higher than 5.3 mm<2> / s under the temperature of 100 DEG C, and the additive still has the good flowing property under the temperature of subzero 50 DEG C and is large in applicable temperature range.

Description

technical field [0001] The invention belongs to the field of rubber oil, and in particular relates to a modified rubber oil additive, a preparation method and the modified rubber oil. 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] CN104693812A discloses a rubber oil additive and anti-aging rubber oil. The rubber oil additive is composed of the f...
