Abstract

The invention relates to the technical field of super-hydrophobic magnetic rubber materials and discloses a super-hydrophobic modified hydrogenated butadiene-acrylonitrile rubber magnetic composite material and a preparation method thereof. A formula for the material comprises the following raw materials: hydrogenated butadiene-acrylonitrile rubber, graphene oxide, a SiO2 nanocomposite material, amodified ferrite nanocomposite material, a plasticizer, an activating agent, an accelerant, an anti-aging agent, a reinforcing agent--carbon black and a vulcanizing agent--sublimed sulfur. Accordingto the invention, nanometer SiO2 is uniformly loaded into an Al-Fe double-metal hydroxide layered structure, so the agglomeration and caking of the nanometer SiO2 are avoided, and the anti-ageing performance of the rubber material is improved; the ferrite composite material with strong magnetism enhances the damping performance and the magnetic performance of the rubber material; and the tridecafluorooctyltriethoxysilane modified SiO2 and an isopropyldioleoylacyloxy(dioctyl phosphate acyloxy)titanate modified ferrite composite material enhance the hydrophobic performance of the rubber material.

Description

technical field [0001] The invention relates to the technical field of superhydrophobic magnetic rubber materials, in particular to a superhydrophobic modified hydrogenated nitrile rubber magnetic composite material and a preparation method thereof. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can restore its original shape after the external force is removed. Rubber belongs to completely amorphous polymerization. It has a low glass transition temperature and a large molecular weight. Rubber materials are mainly divided into nitrile rubber, silicone rubber, fluorine rubber, polysulfide rubber, and polyurethane rubber. Rubber materials are widely used in transportation, agriculture, forestry, water conservancy, military and national defense. , civil engineering, electrical communication and other fields have a wide range ...
