High-temperature-resistant abrasion-resistant non-stick pan coating, preparation method and non-stick pan with same

Abstract

The invention provides a high-temperature-resistant abrasion-resistant non-stick pan coating, a preparation method and a non-stick pan with the same. Nickel plating is conducted on the surface of a metal pan base body through the electrochemical method. Under the action of a magnetic field, a formed surface nickel layer is uniform and flat, and accordingly it is guaranteed that the subsequent coating is flat and uniform. Secondly, an annular structure in a poly(aryl ether nitrile ketone) molecular main chain makes the coating have good high temperature resistance, a molecular structure contains strong-polarity groups, namely nitrile groups, and the nitrile groups generate strong action force on the surface of a metal base material. Thirdly, under the action of irradiation, a silane coupling agent KH792 and poly(aryl ether nitrile ketone) have grafting reaction, and heat resistance is further improved, so that organic solvent molecules cannot permeate into the metal base material, stability is improved, the organic solvent molecules and the surface of the metal base material are connected in a strong chemical bond mode, and adhesion of the coating is greatly improved. Accordingly, the high-temperature-resistant anti-wear non-stick pan coating prepared through the method does not contain fluorine and is resistant to high temperature, abrasion and scratching.

Description

technical field [0001] The invention relates to the technical field of non-stick pans, in particular to a high-temperature-resistant and wear-resistant non-stick pan coating, a preparation method and a non-stick pan. Background technique [0002] Metal pots such as cast iron, stainless steel, aluminum, and aluminum alloy have been the most commonly used food cooking tools for a long time. There are problems such as sticking and burning of food, which not only damage the appearance of food, but also easily cause food to burn. Harmful ingredients such as benzopyrene and acrylamide are harmful to human health. In addition, the food residue adhering to the surface of the pot also brings difficulty to the cleaning of the pot. Non-stick pans have brought great convenience to people's lives because of their advantages such as easy cleaning, non-stick pans for frying / fried food, and less oily smoke, so they have been favored by people since their inception. [0003] At present, th...

However, this material also has many shortcomings, especially the health risks it contains are attracting more and more attention

First of all, the surface non-stick coating formed by Teflon coating is not strong enough to cook with a spatula, and even if only silicone spatulas and wooden spatulas are used for cooking, the coating is easy to absorb after a period of use. Scratches and peelings will affect the structure and performance of the product, and cause the risk of foreign matter in the food; secondly, the temperature of the Teflon coating should generally not exceed 250°C, and according to Chinese cooking habits, for many stir-fried dishes, The temperature in the pot is at least between 300 and 500°C, so it is difficult for people to strictly control it when using it, and it is easy to be damaged by high temperature; third, some studies have found that Teflon materials will release ten gases at high temperatures above 400°C. Several harmful gases have a strong irritating effect on the lungs, and an ingredient called perfluorooctanoic acid ammonium (PFOA) must be added in the production process of Teflon, and concerns about its safety have been expressed in many reports
