Embodiment 1

[0045] In this embodiment, polysilazane is applied to a stainless steel pot.

[0046] Polysilazane is applied on the stainless steel pan body as a non-stick pan coating, and the method for applying polysilazane to the pan body comprises the following steps:

[0047] 1) Polishing: polishing the inner surface of the stainless steel pot to make the inner surface smooth;

[0048] 2) Cleaning: Clean the stainless steel pot body with pure water or deionized water, and then dry it;

[0049] 2) coating: polysilazane is sprayed on the inner surface of the cleaned stainless steel pot body, and the thickness of the sprayed coating is 20um;

[0050] 3) Curing: the sprayed stainless steel pot body was placed in a high-temperature furnace at 100° C. for sintering for 2 hours, thereby forming a non-stick coating on the inner surface of the stainless steel pot body.

Embodiment 2

[0052] In this embodiment, polysilazane is applied to an aluminum alloy pot body.

[0053] Polysilazane is applied on the aluminum alloy pan body as a non-stick pan coating, and the method for applying polysilazane to the pan body comprises the following steps:

[0054] 1) Polishing: Polish the inner surface of the aluminum alloy pot to make the inner surface smooth and flat;

[0055] 2) Cleaning: Clean the aluminum alloy pot body with pure water or deionized water, and then dry it;

[0056] 3) Coating: wipe polysilazane on the inner surface of the cleaned aluminum alloy pot, and the coating thickness is 25um;

[0057] 4) Curing: the aluminum alloy pan body after wiping polysilazane was placed at room temperature 25° C., and cured for 48 hours, thereby forming a non-stick coating on the inner surface of the aluminum alloy pan body.

Embodiment 3

[0059] In this embodiment, polysilazane is applied to a cast iron pot.

[0060] Polysilazane is applied on the cast iron pan body as a non-stick pan coating, and the method for applying the polysilazane to the pan body comprises the following steps:

[0061] 1) Polishing: Polish the inner surface of the cast iron pot to make the inner surface smooth;

[0062] 2) Cleaning: Clean the cast iron pot with pure water or deionized water, and then dry it;

[0063] 3) Coating: Vibration-coat polysilazane on the surface of the cleaned cast iron pot with a coating thickness of 30um;

[0064] 4) Curing: put the cast iron pan body coated with polysilazane in a high-temperature furnace at 180° C. for sintering for 40 minutes, so as to form a non-stick coating on the surface of the cast iron pan body.

Abstract

The invention provides an application of polysiloxane used as a coating on a kitchen utensil. The inner surface and / or the outer surface of the kitchen utensil is coated with Polysiloxane, and the polysiloxane is used as one or more kinds of a non-stick coating, a hydrophobic and oleophobic coating, a mar-proof coating, a high temperature resistance coating and a stain resistance coating. A formed polysiloxane coating is transparent, accordingly, the coated kitchen utensil not only has aesthetic property, safety and excellent performance, but also has higher heat resistance, the maximum heat resistance temperature can reach 1800 DEG C, and the use process is safe; the coated kitchen utensil has ultrahigh rigidity, the rigidity can reach 9 H+, and the coated kitchen utensil is mar-proof, high in antifouling ability, easy to clean and excellent in anti-corrosion performance; a coated pot cover has hydrophobic property and oleophobic property, and people can better observe the cooking condition of the food in a pot; the method that the polysiloxane is applied to the kitchen utensil is simple and easy to operate, the sanding process of the common coating method can be omitted, the production efficiency is improved, and the problems of environmental pollution and noise caused by the sanding process are further reduced.

Description

technical field [0001] The invention belongs to the application field of polysilazane on cookware, and in particular relates to the application of polysilazane on the inner surface and / or outer surface of cookware as a non-stick coating, hydrophobic and oleophobic coating, scratch-resistant coating One or more of layer, high temperature resistant coating and stain resistant coating. Background technique [0002] Cast iron, stainless steel and other metal pots are commonly used cooking tools in daily life, but they are prone to sticking and burning during use, which will not only affect the taste of the cooked food, but also cause some harm to human health. Unfavorable substances, the food sticking to the pan also brings great inconvenience to the cleaning of the pan. [0003] On the market, the common non-stick pan coating is made of polytetrafluoroethylene, but polytetrafluoroethylene is not strong enough, and it is easy to peel off and damage, so it is not recommended to ...
