Problems solved by technology

However, both of the above two coatings contain a certain amount of volatile organic compounds (VOC), which cause environmental pollution.
In addition, the former PTFE coating is a linear polymer with high molecular weight and large volume, resulting in low film density and low heat resistance (only 250°C for long-term use), which is insufficient for the protection of metal substrates. The thermal conductivity is only about 0.25w / mk, which makes the heating efficiency of the product poor
The latter silicone coating, although its hardness can reach 8H and above, has the disadvantage of poor wear resistance and non-stickiness. The product surface is slightly worn, and the non-stickiness will decrease significantly, which cannot meet customer expectations.
[0003] From the above analysis, it can be seen that fluorocarbon coatings have the disadvantages of low hardness, poor compactness, low heat resistance, and insufficient corrosion protection for metals.
Silicone coatings have the disadvantages of poor wear resistance and non-stickiness, short product life, and failure to meet user expectations
Fluorocarbon coatings and silicon coatings have low thermal conductivity, which leads to the disadvantage of low heating efficiency for cookware products
In addition, if fluorocarbon coatings and silicon coatings are used to cover the surface of metal cookware by air atomization spraying, there will be certain organic volatiles, which will easily cause environmental pollution and poor environmental benefits

Description

technical field [0001] The invention relates to the technical field related to the application of cooking utensils and non-stick materials, in particular to a cooking utensil and a preparation method thereof. Background technique [0002] In the traditional cookware and home appliance industry, in order to make the product non-sticky to food, coatings with low surface tension or low coefficient of friction are usually sprayed on the surface of the product, for example, non-stick coatings can be sprayed. Existing non-stick coatings are mainly divided into two classes, one of which is a fluorocarbon coating with polytetrafluoroethylene (PTFE) as the main film-forming substance, and the other is a silicon coating. But above two kinds of coatings all contain a certain amount of volatile organic compounds (VOC), there is environmental pollution. In addition, the former PTFE coating is a linear polymer with high molecular weight and large volume, resulting in low film density and...
