NOVELTY - Aqueous thermal-resistant and anti-corrosion coating with magnetic permeability comprises 60-80 pts. wt. aqueous silicone modified polyester resin, 20-40 pts. wt. amino resin, 10-20 pts. wt. sheet or flake anti-corrosion filler, 5-10 pts. wt. magnetic conductive metal particles, 1-3 pts. wt. silane coupling agent, 0.1-0.3 pts. wt. tetraethyl orthosilicate, 10-20 pts. wt. high temperature resistant pigments, 1-3 pts. wt. auxiliary agents, 1-3 pts. wt. pH regulator and 10-20 pts. wt. water. USE - The aqueous thermal-resistant and anti-corrosion coating with magnetic permeability is useful for manufacturing non-stick pan, cookers and small household appliances for cooking food. ADVANTAGE - The aqueous thermal-resistant and anti-corrosion coating has good corrosion resistance and magnetic function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating, comprising (1) adding neopentyl glycol, trimethylolpropane and isophthalic acid into the reaction kettle, heating to 160-180degrees Celsius for 1-2 hours, heating to 200-220degrees Celsius, continuously reacting for 2-4 hours until the acid value dropped below 10 mg potassium hydroxide (KOH)/g, refluxing xylene as a water-carrying agent, cooling to 140-160degrees Celsius, adding ethylene glycol butyl ether and trimellitic anhydride, continuously reacting until the acid value is 60-80mgKOH/g, cooling to 110-130degrees Celsius, adding tetrabutyl titanate and organosilicon intermediate, reacting for 1-2 hours until transparent, cooling to 80-90degrees Celsius, adding N,N-dimethylethanolamine for neutralization, and adding water for dispersing, (2) dispersing the anti-corrosion filler in 40-60% water to form slurry, adding silane coupling agent, stirring and reacting at room temperature for 4-6 hours, filtering, and adding 40-60% tetraethyl orthosilicate to obtain organically modified anti-corrosion filler, and (3) evenly mixing aqueous silicone-modified polyester resin, amino resin and remaining tetraethyl orthosilicate, adding the organically modified anti-corrosion effect filler, magnetic conductive metal particles, high temperature resistant pigment, auxiliary agent, pH adjuster and remaining water, grinding to obtain aqueous thermal-resistant and anti-corrosion coating with magnetic conductivity.
