▎ 摘  要

NOVELTY - Non-stick coating comprises 50-80 pts. wt. polytetrafluoroethylene, 40-60 pts. wt. polyphenylene sulfide, 7-8 pts. wt. silica sol, 10-15 pts. wt. chromium trioxide, 1-5 pts. wt. graphene and 8-12 pts. wt. coupling agent. USE - The non-stick coating is useful in medical device, preferably medical tray. ADVANTAGE - The non-stick coating: has good wear resistance, thermal stability, good service life and increased effectively improved cleanliness; and is washable. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing non-stick coating comprising (a) mixing polytetrafluoroethylene, polyphenylene sulfide, graphene, chromium oxide and optionally bronze powder to obtain a dispersion and (b) mixing the dispersion liquid obtained in step (a), silica sol, coupling agent, optional leveling agent, optional defoaming agent and optional film-forming aid to obtain the non-stick coating; and non-stick coating is prepared by sintering non-stick coating at high temperature.
