Abstract

The invention discloses a rubber composite modified by carbon nano tubes and graphene jointly. The rubber composite comprises, by weight, 0.001-20 parts of the graphene, 0.001-20 parts of the carbon nano tubes, 1-5 parts of padding, and 50-80 parts of rubber. Compared with existing rubber, the rubber composite has the advantage that mechanical property and electrical thermal properties are improved greatly. The rubber is better in wear resistance, conductivity effect of the rubber is improved, and antistatic and heat dissipation effect of the rubber is further improved.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber composite material jointly modified by carbon nanotubes and graphene. Background technique [0002] Rubber has high elasticity at room temperature, but many of its properties (including tensile strength, hardness, wear resistance, fatigue resistance, electrical conductivity, heat dissipation, etc.) cannot meet the application requirements of polymer materials without reinforcement. Usually need to add fillers (such as carbon black, silica, etc.) to improve its performance. Since the size of graphene and carbon nanotubes (CNTs) is on the nanometer scale, the aspect ratio is large, and it has the advantages of low density, high tensile strength, high modulus, and good electrical and thermal conductivity, it has become a rubber reinforcement modification. Another important filler. [0003] Carbon nanotubes (CNTs) are hollow tubular substances formed by curling hexagonal gr...
