Description
Technical Field

Background
With the continuous development of society, the living conditions of people are gradually improved, the utilization rate of automobiles is greatly improved, and the demand of automobile tires is also continuously expanded. But the tire is a flammable rubber material, which greatly limits its practical application, and heat dissipation of the tire is very important. Heavy duty tires (such as loader, truck and bus tires) are more prone to internal heat build-up too quickly under heavy loads than light duty tires due to poor thermal conduction, causing them to run at relatively high temperatures, which has an impact on the long term thermal durability of the tire. Through improving matrix material thermal conductivity, thereby can guarantee that the tire is in time released away the running temperature of tire with the heat that the tire warp and produce in the use, guaranteed the performance and the life-span of tire.
Graphene has outstanding electrical conductivity, thermal conductivity, and excellent mechanical properties, and thus is widely used. The graphene is applied to tire products, and the special reinforcing effect of the unique two-dimensional honeycomb structure on rubber can optimize the thermal conductivity and mechanical strength of the rubber. But in the practical application process, the defects that the compatibility of the graphene and the rubber is poor, the graphene is easy to aggregate and is difficult to disperse, and the like are found. Therefore, there is a need for a method to improve the compatibility between the filler and the base material, so as to improve the thermal conductivity, flame retardancy and mechanical properties of the tire rubber material.
The metal organic framework material is an organic-inorganic hybrid material formed by self-assembling organic ligands or clusters and metal ions through coordination bonds.
