Description
Technical Field
The invention relates to the technical field of non-stick pan coatings, in particular to a preparation method of a wear-resistant ceramic coating non-stick pan.
Background
With the increasing improvement of living standard of people, more attention is paid to food safety and diet health. The non-stick pan has the excellent characteristics of easy cleaning, non-stick pan, capability of reducing oil smoke to the maximum extent and the like, and gradually replaces the traditional iron pan, so that the non-stick pan is more and more popular with people. According to the different materials of the non-stick pan coating, the non-stick pan coating can be divided into organic coating and inorganic coating. The organic non-stick coating is mainly a polyfluoro resin non-stick coating, and food non-stick is realized by virtue of the characteristics of strong hydrophobicity and low friction coefficient. But the organic polytetrafluoroethylene coating has poor bonding force and strength with the metal substrate of the non-stick pan, is easy to fall off and damage, can be softened in the cooking process, and can only use a wooden shovel and not cook hard food; meanwhile, the non-stick pan is not suitable for cooking acidic food, otherwise, the service life of the non-stick pan is influenced; in addition, the service temperature of the polytetrafluoroethylene coating cannot exceed 250 ℃ generally, and people are difficult to control strictly when using the polytetrafluoroethylene coating and are easy to damage due to dry burning.
The ceramic material is widely applied to the fields of national defense, machinery, chemical engineering, metallurgy, electronics and the like. The alloy has the advantages of high melting point, high hardness, good high-temperature oxidation resistance, strong chemical corrosion resistance and the like, and is always a focus of attention and research of technicians in the field. However, the inorganic ceramic non-stick pan coating is easy to tear due to the difference of expansion coefficients of the metal material and the inorganic material, and is commonly called as 'porcelain explosion', and in addition, a part of inorganic ceramic materials represented by silica sol are often hydrolyzed at high temperature.
Accordingly, there is a need for a method for preparing a ceramic-coated non-stick pan with excellent overall performance.
Disclosure of Invention
In view of the defects of the prior art, the invention provides the preparation method of the non-stick pan with the wear-resistant ceramic coating, and the non-stick pan coating obtained by the preparation method solves the problems of poor wear resistance, easy cracking and the like of the existing non-stick pan coating.
In order to achieve the above purposes, the technical scheme adopted by the invention is as follows:
a preparation method of a wear-resistant ceramic coating non-stick pan comprises the following steps:
step S1: putting the metal pot body into a sand blasting machine, carrying out sand blasting and coarsening treatment by using silicon carbide ceramics or stainless steel balls as shot blasting to form an uneven convex structure on the inner surface of the pot body, then carrying out oil removal treatment, and cleaning for later use;
step S2: respectively weighing 45-65 parts of boron modified silica sol and 30-50 parts of silane modified nano titanium sol in parts by weight; adding 10-15 parts of additive and 1.5-4.5 parts of suspending agent, and uniformly stirring and mixing to obtain coating slurry;

The invention delays or hinders the hydrolysis problem of cations in the high-temperature water boiling process by the modification treatment of the nano silica sol and the nano titanium sol, and further prolongs the service life of the non-stick pan coating. The ceramic film layer after being solidified is slowly damaged due to the hydrolysis of positive ions on the surface in the high-temperature water boiling process of the unmodified nano silica sol and nano titanium sol, and the surface paint film drops when the ceramic film layer is serious.
Preferably, the boron modified silica sol is acidic silica sol modified by boride, and the pH value of the acidic silica sol is 3.5-4.5.
Preferably, the silane modified nano titanium sol is obtained by taking nano titanium oxide sol dispersed by organic acid as a raw material, hydrolyzing vinyl chlorosilane, and then carrying out copolycondensation on the hydrolyzed vinyl chlorosilane and the titanium oxide sol.
Preferably, the pH value of the silane modified nano titanium sol is 3.5-4.5, and the particle size of the nano titanium oxide is 10-40 nm.

Preferably, the organic acid is at least one of oxalic acid, formic acid and acetic acid.
Preferably, the additive is a long chain olefin substituted cage polysilsesquioxane.
Preferably, the suspending agent is sodium bentonite and/or organobentonite.
Preferably, the UV curing is performed by irradiation under a high-pressure mercury lamp with the light intensity of 400-4000 Mw and the wavelength of 200-500 nm, and the curing time is 5-30 min.

The inorganic ceramic non-stick pan has pan body made of iron, aluminum, stainless steel and other metal material and coating made of inorganic material. The expansion coefficients of the inorganic ceramic non-stick pan and the aluminum pan are greatly different, when the pan body is heated, the metal materials of the pan body such as aluminum, iron and the like can expand and extend, and the inorganic coating material has a tendency of tearing the inorganic film layer on the surface of the pan body when the non-stick pan is heated due to the small expansion coefficient, so the inorganic ceramic non-stick pan is commonly called as 'porcelain explosion', thereby the service life of the inorganic ceramic non-stick pan is influenced.
According to the invention, the long-chain olefin substituted cage type polysilsesquioxane is introduced into the main body structure, so that the expansion coefficient of the surface coating of the pot body is closer to that of the metal pot body, the porcelain explosion phenomenon is effectively improved, and the service life of the ceramic non-stick pot is prolonged. The main component modified by the long-chain olefin substituted cage type polysilsesquioxane is an organic-inorganic hybrid structure, and an inorganic phase and an organic phase are combined through a strong chemical bond, so that the temperature resistance of the main structure is further improved, and the thermal expansion performance of the surface coating is improved; due to the particularity of the cage structure, the POSS group has the effect similar to that of an elastomer and has a certain toughening effect.
Meanwhile, the coating prepared by the invention also has excellent comprehensive properties of wear resistance, antibiosis, adhesion resistance, high temperature resistance and the like, and meets the use performance requirement of the ceramic non-stick pan.
The invention has the beneficial effects that:
the non-stick pan ceramic coating prepared by the invention has the characteristics of high temperature boiling resistance and adhesion resistance, has the advantages of cracking resistance, antibiosis and wear resistance, and meets the long-term safe use requirement of the non-stick pan coating.
