Problems solved by technology

The pots prepared by the non-coating anti-rust technology have the advantages of being healthy and beautiful, the surface is hard and easy to stir fry, etc., but the pots prepared by the anti-rust technology are not good in corrosion resistance
[0004] Polymer antirust technology mainly uses polymer sealant, which is mainly used in low-end cast iron spray pots. This technology has the advantages of low cost and good initial corrosion resistance. However, it also has the following disadvantages: polymer texture Soft, the polymer layer has been destroyed by the spatula when used at home, resulting in a sharp drop in corrosion resistance; consumers have an "unhealthy" impression of polymer cookware products
[0006] However, the corrosion resistance mechanism of the sealing layer is to block the pores of the coating and prevent the entry of corrosive media. The sealing effect depends entirely on the quality of the sealing layer. Once there are small pores or cracks in the sealing layer, the long-lasting corrosion resistance effect will be greatly reduced.

preparation example Construction

[0042] A method of preparing an anti-corrosion coating according to an exemplary embodiment of the inventive concept includes: providing a substrate; applying a corrosion-resistant powder on the surface of the substrate to form a transition layer; and applying a modified sealer on the surface of the transition layer to form a seal Floor.

[0043] According to an exemplary embodiment of the present inventive concept, the substrate may be a substrate known in the art that needs to be treated with anti-corrosion. For example, in accordance with the present inventive concept, the substrate may comprise a cast iron cookware blank. However, the present inventive concept is not limited thereto, and those skilled in the art may select an appropriate substrate according to the present inventive concept.

[0044] According to an exemplary embodiment of the present inventive concept, in order to facilitate subsequent processes and product quality, the step of providing the substrate may...

Embodiment 1

[0060] Prepare the cast iron pot embryo, use a cleaning solution to clean the surface of the pot embryo, and then dry it, wherein the cleaning solution includes 5% fatty alcohol polyoxyethylene ether, 9% coconut oil alkanolamide, 3% Triethanolamine oleate, 9% monoethanolamine, 2% benzotriazole and 72% water; and then roughened the surface of the pot embryo by sandblasting, so that the surface roughness of the pot embryo was 1.5 μm.

[0061]A zirconia powder having a particle size of 50 μm was prepared, and the zirconia powder was subjected to low-pressure plasma spraying. The low-pressure plasma spraying process includes: preheating the cooker to 150°C; pumping the vacuum of the spraying chamber to 3Pa, and then rushing into argon to 6×10 3 Pa; plasma arcing, adjust the transfer arc power to 30Kw, adjust the arc current to 600A, set a spraying distance of 120mm and a spraying angle of 60°, and then spray the pot embryo, wherein the powder feeding speed is 25g / min , the hydrog...

Embodiment 2

[0067] The difference from Example 1 is that the transition layer is formed by spraying with titanium oxide powder instead of zirconium oxide powder.

Abstract

The inventive concept provides a modified sealant, an anti-corrosion coating, a method of making the anti-corrosion coating, and a cookware including the anti-corrosion coating. The modified sealing agent comprises a carbon fluoride material and a sealing agent, the carbon fluoride material comprises at least one of graphite fluoride and graphene fluoride, and the anti-corrosion coating comprising a sealing layer prepared by using the modified sealing agent of the inventive concept has an excellent and lasting anti-corrosion effect.

Description

technical field [0001] The inventive concept relates to the field of rust prevention, and more particularly, to a modified sealant, an anti-corrosion coating and a method for preparing the anti-corrosion coating. Background technique [0002] The current anti-rust technology is divided into three types, namely, uncoated anti-rust technology, polymer anti-rust technology and inorganic layer anti-rust technology. [0003] Uncoated rust prevention technology mainly adopts surface nitriding, anodizing and chemical passivation and other technologies, which are mainly used in refined iron true stainless and cast iron true stainless. The cookware prepared by the uncoated antirust technology has the advantages of healthy and beautiful appearance, hard surface and easy to stir fry, etc. However, the cookware prepared by the antirust technology has poor corrosion resistance. [0004] The polymer anti-rust technology mainly uses polymer sealants, which are mainly used in low-end cast ...
