Laminated Hot Press Molding Process and Performance of Graphene Micro-nano Sheets Composite Sealing Gasket
Sealing materials have a wide range of applications in the fields of mechanical power and petrochemicals,they are important basic components for preventing leaks and maintaining the normal operation of equipment.Graphene micro-nano sheets have become one of the key sealing materials due to their excellent thermal conductivity,corrosion resistance,and mechanical properties.This article mainly uses graphene micro-nano sheets as the main filler,phenolic resin(PF)and polyvinyl butyral(PVB)as binders,combined with tape casting and hot pressing technology,to study the effects of graphene micro-nano sheets content,binder ratio,and hot pressing pressure on the tensile strength,compression rate,and rebound rate of composite sealing gaskets,and explore the hot pressing and laminated object manufacturing process of graphene micro-nano sheets composite sealing gaskets.The results show that when the content of graphene micro-nano sheets is 55%,the PF/PVB mass ratio is 8∶15,the molding pressure is 15 MPa,the molding temperature is 120℃,and the insulation time is 30 min,the graphene micro-nano sheets composite sealing gasket has the best molding processability and property,which can be prepared to meet the quality requirements of graphene micro-nano sheets composite sealing gaskets.
