AI Technical Summary

Technical Problem

Existing non-stick coatings struggle to achieve both initial and long-lasting non-stick properties. Fluoropolymer coatings are easily damaged by spatulas and age at high temperatures, while ceramic coatings experience rapid silicone oil consumption at high temperatures. Other materials have limited effectiveness when oil is present.

Method used

A non-stick coating with an amorphous structure is formed by sintering a soluble salt solution and framework silicate particles dispersed therein, including silicate catalysts. The soluble salt enters the framework silicate structure and chemically bonds with it, forming a coating with low surface energy and high degree of amorphization.

Benefits of technology

It achieves toughness and heat resistance of the coating under alternating hot and cold environments, maintains initial non-stickiness and extends long-term non-stickiness, and improves the wear resistance and service life of the coating.

Abstract

The application provides a non-stick coating, a non-stick cookware, a non-stick coating and a preparation method thereof. The non-stick coating comprises a soluble salt solution and particles dispersed in the soluble salt solution, the particles comprise a framework silicate and a silicate catalyst, the soluble salt solution comprises a soluble salt and a solvent, wherein the weight percentage of the framework silicate is 30-40%, the weight percentage of the silicate catalyst is 2-5%, the weight percentage of the soluble salt is 0.5-2%, and the balance is the soluble salt solution, based on the total weight of the non-stick coating being 100%. The non-stick coating according to the application can obtain a non-stick coating with good initial non-stickiness, persistent non-stickiness and bonding force.
