Abstract

The invention relates to a preparation method of a protonized ionic liquid modified rubber / inorganic filler composite material, which comprises the steps of: 1, preparing a structure of a functional protonized ionic liquid; and 2, ensuring that the functional protonized ionic liquid is used for an in situ modified inorganic filler reinforced rubber composite material. The invention can effectively lower the agglomeration among strong-polarity inorganic fillers, improves the diffusion of the fillers in a rubber base body, and is beneficial to improving the processing property, the vulcanization characteristic, the mechanical property, the abrasive resistance and the like of the rubber / inorganic filler composite material. The method has the characteristics of popularization and low cost, and can be widely applied to preparing various high-property rubber / inorganic filler composite materials.

Description

technical field [0001] The invention relates to a preparation method of a protonated ionic liquid modified rubber / inorganic filler composite material. technical background [0002] Ultra-fine inorganic fillers (such as silica and clay) have excellent reinforcing effects on various rubbers, and have gained important applications in the fields of light-colored rubber products and green tires. However, the strong polarity and high surface energy of inorganic fillers make their dispersion in the rubber matrix difficult, which not only affects the properties of rubber, but also increases the processing energy consumption. At the same time, in rubber processing, processing aids (such as accelerators, activators, vulcanizing agents, stabilizers) will have serious surface adsorption due to the strong polarity of the surface of ultrafine inorganic fillers, reducing the efficiency of the aids. Therefore, when using ultrafine inorganic fillers to reinforce rubber materials, surface pr...
