[0059]The pH value is very critical to the preparation of ceramic coatings. The performance and use time of the ceramic coatings will be very different in the reaction at different pH values. In order to ensure the accuracy of the pH value during the system reaction, the amount of organic acid added in the catalyst should be accurate. Because the amount of catalyst organic acid added in the coating is very small, adding it alone is likely to cause a large error, and the pH value of the reaction will have a large error. The addition of deionized water after dilution can reduce the addition error of the catalyst, which is beneficial to The control of the pH value of the ceramic coating reaction enables the ceramic coating to achieve the desired performance.

Abstract

The invention discloses a ceramic coating for the surface of an energy-gathering ring of a gas stove and a preparation method and an application method thereof. The ceramic coating comprises the following components and their mass percentages: A component: 67.5-69.5% color paste; B Component: 30.5‑31.5% silane; C component: 0.7‑0.8% catalyst. The invention solves the problem that the silicone coating on the surface of the energy-gathering ring of the gas stove has poor temperature resistance and is easy to decompose and change color when burning, and has the characteristics of good high temperature resistance, no decomposition, no discoloration and no release of smoke under high temperature , is very suitable as a surface coating for gas stove energy-concentrating rings.

Description

technical field [0001] The invention relates to a ceramic coating for the surface of an energy gathering ring of a gas stove and a preparation method and application method thereof. Background technique [0002] The energy gathering ring of the gas stove has two main functions: first, it can gather the flame to prevent heat loss and greatly improve the thermal efficiency; [0003] The energy gathering ring of gas stoves is generally made of cast iron or stainless steel. Although it can work continuously at a high temperature above 800 °C, if there is no coating protection, the surface will be oxidized and discolored after a period of use, which not only affects the appearance, but also Affect the service life of the energy gathering ring. [0004] In order to protect the energy gathering ring of the gas stove from being oxidized and discolored, the current mainstream solution is to spray black paint on the surface, of which the most commonly used is silicone paint. Although...
