Abstract

The invention provides a modified ethylene-propylene-diene monomer rubber material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 40 to 80 parts of ethylene-propylene-diene monomer rubber, 15 to 30 parts of butyronitrile rubber, 18 to 25 parts of natural rubber, 10 to 20 parts of methyl vinyl silicone rubber, 12 to 18 parts of butadiene rubber, 8 to 15 parts of nano calcium carbonate, 7 to 13 parts of nano silicon dioxide, 5 to 10 parts of nano carbon black, 6 to 18 parts of nano graphene, 5 to 12 parts of nano fibers, and 3 to 8 parts of nano montmorillonite. The preparation method of the modified ethylene-propylene-diene monomer rubber material comprises the following steps: firstly, preparing a rubber compound; then carrying out surface modification on an auxiliary nano-material by adopting an intercalating agent, and then blending the auxiliary nano-material subjected to surface modification with a rubber composite material to enable the auxiliary nano-material to be dispersed into the rubber composite material so as to enhance acting force of auxiliary filler and an interface of a rubber compound. The material prepared by the invention is excellent in performance, and is suitable for a rubber material for a robot vacuum suction cup, so that the working efficiency of a robot under different working environments is improved and the service life of the robot is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of rubber material preparation, and in particular relates to a modified EPDM rubber material and a preparation method thereof. Background technique

[0002] The molecular chain structure of EPDM rubber is characterized by the fact that the molecular chain basically does not contain unsaturated bonds, the steric hindrance of the substituent is small, and the molecular chain is flexible. It is a saturated non-crystalline rubber. This molecular structure determines that EPDM rubber has good comprehensive properties compared with other diene rubbers: high dynamic mechanical properties, weather resistance, corrosion resistance and ozone resistance, etc., and has good electrical insulation, Low density, high filling, hot water resistance and water vapor resistance, etc., and also has good compatibility with various high polymers. It can be widely used in other products such as waterproof materials for building ma...
