Abstract

The invention discloses a high-strength melt dripping resistant graphene / PET composite plate and a production method thereof. The graphene / PET composite plate is produced through melt-extrusion of a graphene / PET composite nano-material, and the graphene / PET composite nano-material is obtained through adding plicated spherical grpahene oxide and a catalyst into a PET precursor and carrying out in situ polycondensation. The method avoids stacking of the graphene oxide in the esterifying stage, greatly saves the cost, and increases the production efficiency. Obtained graphene is well dispersed in a polymer matrix, and a small amount of the graphene is added to significantly improve the melt dripping resistance, the yield strength and high-temperature yield strength of the composite plate. The production method is simple and effective, and the obtained composite plate has superior performances, and can be applied to the fields of building materials, refractory materials and heating kitchen tools.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a high-strength droplet-resistant graphene / PET composite plate and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) has high mechanical strength, stiffness and hardness, good sliding performance and wear resistance, good electrical insulation, very good creep resistance and dimensional stability (better than POM ) and physiologically inert (suitable for contact with food). Weather resistance, chemical resistance, good stability, low water absorption, weak acid and organic solvent resistance, but not hot water soaking resistance, not alkali resistance. However, in the face of the rapid development of society, people have put forward many new requirements for the mechanical, thermal and electrical properties of PET. If the performance of PET can be further improved, or given new properties, it will not only further broaden the applicat...
