Abstract

The invention discloses a tough heat-conductive antibacterial non-stick coating which is prepared from, by weight, 1-2 parts of graphene powder, 10-20 parts of nano SiO2 dispersion liquid, 10-15 parts of aluminum oxide sol, 10-15 parts of zirconium oxide sol, 2-4 parts of bentonite, 1-3 parts of black iron oxide, 8-10 parts of polyimide, 30-50 parts of polytetrafluoroethylene water-based resin, 5-20 parts of acrylic acid, 5-8 parts of water-soluble polyester modified epoxy resin, 1-3 parts of fluorosilicone oil, 1-2 parts of silver nitrate, 1-2 parts of aluminum nitrate and 3-5 parts of butyl cellosolve. The coating is good in ductility, high in toughness, resistant to wear, not prone to cracking and high in heat conductivity, has the antibacterial function and can be widely applied to kitchen cookware and tableware.

Description

technical field [0001] The invention relates to the technical field of coatings for kitchen utensils, in particular to a tough, heat-conducting, antibacterial and non-stick coating applicable to cooking utensils such as frying pans and baking pans and a preparation method thereof. Background technique [0002] At present, there are two main types of non-stick coatings commonly used in the market, one is fluorine coatings based on polytetrafluoroethylene (PTFE), such as Teflon; the other is based on silica sol and alkoxy Silane monomers are ceramic coatings prepared by sol-gel method (sol-gel). The inorganic nano-coating prepared by sol-gel technology overcomes the problems of poor temperature resistance, flame resistance and hardness of traditional organic coatings, and it has the characteristics of inorganic materials such as thermal stability, wear resistance, scratch resistance and non-combustibility. The coating of this system mainly uses water as a solvent, and there i...
