Abstract To investigate the mechanical properties of phenolic resin-modified epoxy resin in different structures and
their effects on the friction and wear coating properties, and acquire theoretical support for the design of highperformance,
long-life bonded solid lubricating coatings, the relationship between crosslinking density and mechanical
properties of modified epoxy resin (EP)/boron phenolic resin (FBB) and epoxy resin (EP)/linear phenolic resin (SG)
was analyzed using dynamic thermomechanical property testing (DMA) and V-block friction and wear testing. The
influence of different crosslinking density resins of the coating was also investigated. The results showed that when the
ratio of epoxy resin/phenolic resin increases, the crosslinking density of the resin gradually decreases, while the elastic
modulus first increases before it decreases. When the ratio is 5:1, the elastic modulus reaches its maximum, and the
wear resistance life is the longest. Linear phenolic (SG) modified epoxy resin (EP) has a lower crosslink density at the
maximum elastic modulus, resulting in a longer wear resistance life. A resin system with suitable crosslinking density
can significantly improve the wear resistance life of coatings. By synthesizing resin systems with suitable cross-linking density, the wear resistance life of bonded solid lubricating coatings can be considerably enhanced, providing a
scientific basis for developing high-performance coatings with longer life.
