Description
[technical field]
The present invention relates to a kind of preparation method who is applied to the high-temperature resistant antibacterial non-stick paint of cooker medicine food and special purpose, belong to the chemistry painting industry technical field.
[background technology]
Non-viscous paint be a kind of coatingsurface be difficult for being adhered to by other viscous substances or adhere after the speciality coating that easily is removed.This kind coating is extremely low because of the surface energy of its coating that forms, non-stick property characteristics such as frictional coefficient is little, easy slip, is widely used in industries such as household electrical appliance, culinary art kitchen tools, automobile, machinery, chemical industry.Non-viscous paint more and more causes coating R﹠D work person's extensive concern as a kind of environment-friendly type speciality coating practical, with high content of technology.How the non-viscous paint technical sophistication at how disperseing the fluoro-resin micro mist, chooses binding resin, how to make mutual compatibility of each resin etc. be still the important topic of present development release coating.Non-viscous paint world demand amount in recent years increases with annual 20%～25% speed.The research and development of China's non-viscous paint also are in the starting stage, and product is also less, can't satisfy domestic demand far away.
Compare with the common non-viscous paint on the market, it is good etc. that this non-viscous paint system has a Heat stability is good, anti-adhesion effects, can be in-20 ℃ of-280 ℃ of scopes life-time service, the short period of time can anti-350 ℃ high temperature.The cooker undercoat that coating forms is at pancake, scrambled egg, fried fish, sticking and be easy to clean when boiling milk; Iron plate is sprayed with this coating, and is when ironing clothes, smooth and pollution resistance good; More superior in aspect performances such as corrosion-resistant, sticking power, nontoxic, hardness.Except that indivedual media, can anti-various acid, alkali, salt and organic medium (solvent); Hardness can not occur scratching delamination with 3H pencil power paddling with the 1-2 kilogram on coating; Good with the metal bonding performance, coating adhesion is strong, and it is once sintered to carry out primary coating, to improve the work efficiency save energy; Because the solid constituent of coating is nontoxic, contains ammonium perfluorocaprylate anything but, it is reasonable to form technology, so coating is nontoxic, can be widely used in cooker, medicine, food product containers etc.
But, be easy to breed bacteria because most of coating are basic ingredient with the organic compound all.And some malignant bacterias just might influence the healthy of people.Medical research shows that the generation of human diseases is exactly by due to various harmful germs and the virus.Non-viscous paint contacts with the mankind frequently especially, interwoveness.
[summary of the invention]
The purpose of present technique invention is to overcome the weak point that prior art exists, and a kind of practicality, high temperature resistant, antibacterial non-stick paint technology of preparing are provided in the non-viscous paint field.
At present, coating mainly contains natural antibacterial agent, organic antibacterial agent, inorganic antiseptic three major types with antiseptic-germicide, inorganic antiseptic is nanometer silver particularly, because surface effects, its antibacterial ability is that the micro nanometer silver ionic is more than 200 times, anti-microbial property also is far longer than traditional silver ion disinfectant, along with coating industry is strict further to the control of the harmful organic compound content of volatility, if there is harmful microorganism in film coated surface, after human body contacts, also can infect various diseases, threaten HUMAN HEALTH.Therefore, in coating, add a small amount of nano-silver powder, make it have anti-microbial property and have practical significance.
For achieving the above object, the present invention takes following technical scheme: the nanometer silver powder of a kind of high-temperature resistant organic silicon resin, the tetrafluoroethylene wax powder that cannot not play stickingly effect, a germicidal action is mixed.
Coating of the present invention also further comprises talcum powder, flatting silica, butanone, carbon black.
For making coating of the present invention reach better effect, increased esters solvent, this esters solvent is a 1-Methoxy-2-propyl acetate
For obtaining more superior performance, coating of the present invention also adds dispersing auxiliary.
Coating raw material of the present invention adopts high speed dispersion and grinds, and adds not sticking auxiliary agent then, obtains high-temperature resistant antibacterial non-stick paint.
Compare with existing coating technology, coating of the present invention has the following advantages: antibacterial effect significantly, sticking effect is obvious.Manufacturing process is simple, with low cost simultaneously, has application promise in clinical practice.
