Description
Technical field
The invention belongs to paint fields, are related to a kind of Ceramic Composite coating, and in particular to it is a kind of for ceramic pan it is equal from
The preparation method of the ceramic coated composite coating of son.
Background technology
Since frying pan, slaughterhouse or pan are the conditioning most important utensil of food, with the health of people and daily
Live closely bound up, therefore, dish non-stick pan when the good cookware of quality requires heated average, cooking, at the same can antirust resist it is resistance to
Erosion, can be only achieved the requirement of user in this way.
Cookware used in cooking food at present, it is most of to be made of stainless steel or aluminium alloy, and be made using aluminium alloy
Cookware have the characteristics that light-weight, manufacturing cost is cheap, so the pot occurred in the market is substantially that aluminum alloy materials are made.
Existing non-stick pan coats the coating of one layer " Teflon " in the bottom of a pan, and " Teflon " is the general name of fluorine resin,
Including polytetrafluoroethylene (PTFE), perfluoroethylene-propylene and various fluorinated copolymers, due to these compounds have high temperature resistant, low temperature, from
The advantages that lubricity, chemical stability, therefore it is widely used in non-sticking cooking utensils, waterproof ventilative material (such as waterproof clothes), leather, automobile
Component and micro-wave oven popcorn bag etc..
Perfluorooctanoic acid is the necessary additive produced during Teflon, although without trace in finished product,
It may still be decomposed under high temperature.The study found that Teflon is at high temperature, ten several pernicious gases can be released, some breathings are caused
The animal dead of road sensitivity.After the perfluorooctanoic acid that chemical property is stablized enters natural environment and human body, meeting long-term existence is decomposed
It is very slow.Studies have shown that low dosage perfluorooctanoic acid is present not only in river, ocean and soil, the blood of people is existed in
In.Since this artificial compound has been proved carcinogenesis and other adverse consequences in zoopery, if being widely present in
In natural environment and human body, consequence is troubling.It is, thus, sought for the non-stick steel of completely new coating structure.
Ceramic material has extensive use in fields such as national defence, machinery, chemical industry, metallurgy, electronics.Wherein, titanium carbide TiC
Ceramics have fusing point high, and good heat conductivity, hardness is big, and chemical stabilization is good, does not hydrolyze, and high-temperature oxidation resistance is good, coefficient of thermal expansion
Small, the advantages that anti-thermal shock and chemical resistance are strong is always the hot spot of countries in the world material scholar research.
Invention content
The purpose of the present invention is raising cooker surface safety and environmental protection, coating are stablized under the high temperature conditions and efficiency can be improved
