Abstract

The invention discloses a rubber plasticizing homogenizing agent and a preparation method thereof. The method comprises the following steps: reacting 70-100 parts of heavy traffic petroleum asphalt, 0-30 parts of optional hydrocarbon compound and derivatives thereof and 0.1-9 parts of catalyst with modifier at 90-180 DEG C, keeping the reaction at 100-180 DEG C for 0.5-3 hours, and carrying out vacuum distillation until the softening point of the product is 80-130 DEG C, thereby obtaining the rubber homogenizing agent. By modifying the heavy traffic petroleum asphalt and hydrocarbon compound and derivatives thereof with the modifier, the preparation method disclosed by the invention obviously lowers the content of cancerigenic polycyclic aromatic hydrocarbons, and overcomes the defects of high bubbling tendency and kettle overflow in production in the prior art, thereby enhancing the production safety. The rubber plasticizing homogenizing agent disclosed by the invention can mix the rubber materials with different polarities and different viscosities more homogeneously and sufficiently, and is beneficial to powder dispersion, so that the rubber materials in different batches have stable and homogeneous quality.

Description

technical field [0001] The invention relates to chemical auxiliary agents, in particular to an aromatic hydrocarbon resin used as a plasticizing and leveling agent for rubber and tires and a preparation method thereof. Background technique [0002] The main function of the leveling agent is to solve the dispersion between rubbers of different polarities or between rubbers and rubber-like polymers. In terms of chemical composition, the leveling agent is a mixture of different polar components such as aliphatic hydrocarbons, cycloalkanes and aromatic hydrocarbon resins. This mixture with different polarities shows good compatibility with various elastomers, and can promote mixing by softening and infiltrating the interface of polymers, making it easy for polymer molecules of different polarities to interact with each other. Move each other to achieve the purpose of blending. At the same time, the leveling agent also has the functions of plasticizing, viscosifying and lubrica...
