Problems solved by technology

[0004] However, the non-stick coating formed by the "Teflon" coating is not strong enough to be used for cooking with a spatula. Even if only a silicone spatula and a wooden spatula are used for cooking, the coating is prone to scratches and peeling off after a period of use. It leads to the risk of foreign matter in food; in fact, the temperature of "Teflon" coating generally cannot exceed 250 ℃, and according to Chinese cooking habits, the temperature in the pot for many stir-fried dishes is at least between 300-500 ℃ , the coating is easily damaged due to high temperature; at the same time, according to research, the "Teflon" material will release more than a dozen harmful gases at a high temperature above 400 °C, which has a strong stimulating effect on the lungs and brings people Security risks

Abstract

The invention provides a non-stick coating for a stainless steel pot and a preparation method thereof. The non-stick coating comprises the following components: mesoporous aluminum oxide, nano zirconium oxide, nano calcium carbonate, nano silicon dioxide, nano silicon carbide, graphene, ethanol, deionized water, a titanate coupling agent, tributyl citrate and lauric acid. The modified microspheres are prepared, the modified microspheres, tributyl citrate and titanate are subjected to a coupling reaction, and lauric acid is further used for grafting, so that the prepared non-stick coating has excellent high-temperature resistance, wear resistance and antibacterial performance, is safe and stable, and has better cooking experience feeling.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a non-stick coating for stainless steel pots and a preparation method thereof. Background technique [0002] Stainless steel pots and utensils are widely used food cooking tools, but it is easy to cause the food to stick to the pan and burn, which not only damages the appearance and taste of the food, but also easily causes the food to produce harmful ingredients such as benzopyrene and acrylamide, which endanger human health . In addition, the food residue adhering to the surface of the pot is not easy to clean, which brings inconvenience to cooking. [0003] Non-stick pans have been favored by people in recent years because of their advantages such as easy cleaning, non-stick pan for frying / frying food, and less oily smoke. The reason why non-stick pans do not stick is mainly due to the non-stick coating inside the pan. At present, the non-stick coating materials o...
