Problems solved by technology

[0004] The series of oil products after further refining and saturation treatment can meet the health, safety and environmental protection (HES) standards, but they are different from aromatic oils in chemical composition, and there is a big difference in compatibility with rubber in use, so Affecting the viscosity and other properties of the rubber compound is a potential disadvantage of environmentally friendly operating oils, especially for environmentally friendly oils required in low hysteresis loss tire formulations, which can improve the compatibility between oil and rubber. additive

Abstract

The invention discloses an additive for enhancing the intermiscibility between tire rubber extending oil and rubber and a preparation method thereof. The preparation method comprises the following steps of: (1) weighing 40-45 parts of styrene, 10-25 parts of indene, 20-30 parts of cyclopentadiene, 0-5 parts of vinyltoluene, 0.05-0.15 part of dication aluminum trichloride and 100-150 parts of auxiliary; (2) mixing the raw materials and undergoing a dication catalysis low-temperature reaction; (3) standing and delaminating a reaction product, taking lower layer liquid and removing a residual fraction to obtain paste; and (4) weighing 40-50 parts of paste, 35-45 parts of isoparaffin and 10-20 parts of aromatic oil, mixing the raw materials and performing hydrogenation to obtain the additive. By adopting the additive, the intermiscibility between environmental-friendly oil and rubber can be improved. The additive is added into the environmental-friendly oil. An obtained environment-friendly oil product can be well soluble with rubber. The additive has high physical property, and reaches and surpasses the aromatic oil index.

Description

technical field [0001] The invention relates to an additive for tire rubber extender oil, in particular to an additive capable of significantly improving the compatibility between tire rubber extender oil and rubber and a preparation method thereof, belonging to the field of additives for tire rubber extender oil. Background technique [0002] From January 1, 2010, if tires contain filler oils that do not meet the requirements of the latest EU health, safety and environmental protection regulations, they cannot enter the European market. Although the regulation was issued by the European Commission (Directive 2005 / 69 / EC), its shockwaves are being felt globally, as Europe is the the final market for its products. Due to the high content of polycyclic aromatic hydrocarbons (PAH) and other polycyclic aromatic (PCA) compounds, the main product traditionally used as tire rubber extender oil, namely aromatic hydrocarbon oil (DAE), does not meet the requirements of the new regulat...
