- Abstract
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 micronano 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 °C, 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.
