Abstract

The invention provides a reaction kettle inner wall nano coating and a preparation method thereof. The coating comprises the following components in percentage by mass: 20-30wt% of polyurethane modified epoxy resin, 10-20 wt% of composite C60, 5-10 wt% of nano bismuth ferrite, 10-20 wt% of nano nickel oxide, 1-5 wt% of ethylene glycol monohexyl ether, and 1-10 wt% of dimethylethanolamine; and a solvent. According to the reaction kettle inner wall nano coating, the nano bismuth ferrite and the nano nickel oxide are added into the surface coating, so that the effect of reducing the friction coefficient can be achieved, a self-lubricating material is formed, and even a super-lubricating function is obtained, and therefore, the nano coating for the inner wall of the reaction kettle is not easyto absorb water, easy to clean and resistant to acid and alkali. The preparation method of the reaction kettle inner wall nano coating is simple and feasible, green and environmentally friendly, andis an environment-friendly process.

Description

technical field [0001] The application relates to a nano-coating on the inner wall of a reactor, in particular to a nano-coating on the inner wall of a reactor and a preparation method thereof, belonging to the field of nanotechnology. Background technique [0002] The reactor is a commonly used instrument in the existing laboratory. It can not only reduce energy consumption but also achieve the synthesis effect that cannot be achieved by ordinary heating. Therefore, more and more reactors are put into use, but the raw materials in the chemical reaction Strong acidity or alkalinity will corrode the inner wall of the reactor, and the corroded reactor material will enter the reaction, affecting the reaction yield and even the progress of the reaction. It is more toxic to the reaction. Therefore, an inert coating is required for the reaction The inner wall of the reactor is protected. In the prior art, water-based resin is generally used as the main material of the reactive coa...
