Enamel material for 1Cr18Ni9Ti stainless steel surface and preparation method thereof

Abstract

The invention provides an enamel material for 1Cr18Ni9Ti stainless steel surface and a preparation method thereof. The enamel material is prepared by sintering a raw material comprising the following ingredients: 39-42 parts by weight of silicon dioxide, 12-14 parts by weight of aluminum oxide, 6-9 parts by weight of titanium dioxide, 0.5-1 parts by weight of magnesium oxide, 5-7 parts by weight of zinc oxide, 3-5 parts by weight of calcium oxide, 0.5-3.5 parts by weight of nickel oxide, 5-7 parts by weight of boron trioxide and 18-20 parts by weight of sodium oxide. The enamel material provided by the invention has high temperature tolerance, the heat resistance temperature of the enamel material can be higher than 600 DEG C, the acid and alkali corrosion resistance is relatively excellent, the enamel material is guaranteed to be well matched with a 1Cr18Ni9Ti stainless steel base material under a high temperature, and the enamel material can be effectively prevented from dropping.

Description

technical field [0001] The invention relates to an enamel material used on the surface of 1Cr18Ni9Ti stainless steel and a preparation method thereof. Background technique [0002] Industrial manufacturing technology in the chemical industry generally includes processes such as raw material purification, reaction preparation, and separation and purification of reactants. Among them, the process of chemical reaction is complicated, and generally needs to be carried out at high temperature, and the reaction materials have various phase states, and the reaction environment is relatively harsh. As the core equipment and reaction site of industrial manufacturing technology, chemical reactors have been in complex, harsh and high-temperature environments for a long time, which makes chemical reactor materials need to have high stability of chemical medium resistance and high temperature resistance. [0003] Stainless steel has high strength, high hardness and good machinability, a...
