Abstract

The invention provides a preparation method of a slow-release flame color-adding coating. The preparation method specifically comprises the following steps: mixing tetraethoxysilane, hydrochloric acid, a silane coupling agent, a silicon oxide powder and water serving as raw materials to prepare silicon oxide sol; coating the silicon oxide sol on a metal material substrate; then drying and sintering to obtain a porous silicon oxide coating; and soaking the porous silicon oxide coating in a flame coloring agent ion solution, taking out, drying, and sintering to obtain the slow-release flame color-adding coating. The raw materials used in the method are low in price and easy to obtain, the preparation method is simple in process, the requirement for a flame device is low, and the coating can be coated on the surface of a flame outlet component or an independent flame coating supporting structure; the obtained coating is high in bonding strength with a metal substrate, good in ablation resistance and thermal shock resistance and not prone to falling off in the combustion process; and the obtained coating is a porous structure, and in the combustion process, the porous structure can effectively reduce flame agent consumption and can effectively prolong the service life of the flame agent.

Description

technical field [0001] The present application relates to the technical field of flame color, in particular to a method for preparing a slow-release flame color coating. Background technique [0002] The combustion of gas or liquid fuel produces a flame, and the color of the flame is closely related to the type of fuel and impurity atoms. Generally, the color of the flame is caused by the flame reaction. The atoms inside the substance absorb energy under the excitation of external energy (combustion flame), and the orbit of the lower energy of the electron jumps to a higher energy orbit. The electrons in the higher energy orbit are unstable. It will quickly jump back to a lower energy orbit, and then release the excess energy in the form of light. If the wavelength of the emitted light is in the range of visible light (wavelength is 400nm ~ 760nm), the flame will show visible color. At present, propane and butane are the most commonly used fuels for gas lighters and torche...
