Title: Metal-containing composition for inhibiting oxidation of metallic material at high temperature and production thereof
Inventor: UCHIDA FUMIO
IPC: C09D1/00
Filed: 1987-02-06
Abstract: PURPOSE:To form a high performance film for inhibiting the oxidation of a metallic material at high temp., by bringing a metallic compd. such as boric acid or a specified metallic oxide, alcoholamines and carboxylic acid as starting materials into a reaction under heating and by applying the resulting metal-contg. compsn. to the metallic material. CONSTITUTION:One or more kinds of metallic compds. selected among boric acid, boric anhydride or ammonium borate and carboxylates, oxides or hydroxides of Al, Ga and In, one or more kinds of alcohol-amines such as ethanolamine and carboxylic acid as starting materials are gradually or simultaneously brought into a reaction under heating in the presence or absence of an org. solvent to obtain a metal-contg. compsn. When the compsn. is applied to a metallic material and heated, a high performance film for inhibiting oxidation is formed. The compsn. produces a significant oxidation inhibiting effect even in the form of a continuous liq. film formed only by applying the compsn. The formation of oxide scale on the material during resistance welding can be perfectly prevented by previously forming the liq. film on the surface of the material.
