Rubber compression heat generation refers to the rubber material in dynamic compression conditions, due to the molecular chain of friction, entanglement and fracture and other processes to produce heat. If this heat is not emitted in time, it will accumulate inside the rubber, leading to an increase in material temperature, which in turn leads to a series of adverse consequences. The basic principles of heat generation in rubber compression can be summarised as follows.
The basic principles of heat generation in rubber compression can be summarised as follows
Friction of molecular chains: In the dynamic compression process, relative movement occurs between the molecular chains of rubber, generating frictional heat. The size of this frictional heat and molecular chain flexibility, crosslinking density and other factors.
Entanglement of molecular chains: rubber molecular chains are entangled with each other in three-dimensional space, forming a network structure. In the dynamic compression process, the entanglement of the molecular chain will occur relative displacement, generating heat. The number and distribution of the entanglement points have an important influence on the thermal properties of rubber.
Breakage of molecular chains: During dynamic compression, the molecular chains of rubber may be subjected to excessive stress and break, generating heat. The breakage of the molecular chain leads to a decrease in the mechanical properties of the rubber material and an increase in the amount of heat generated.
