Problems solved by technology

[0002] The current metal heat treatment protective coating can effectively protect the metal during the metal heat treatment process, but the metal protection during the heat treatment process is relatively simple, either to prevent carburization, or to prevent boronization, or to prevent decarburization, or to prevent debonding. Hydrogen, etc.; in addition, after heat treatment, some protective coatings must be sandblasted to remove the coating

Abstract

The invention provides protective paint for heat treatment of metal, which is characterized by being prepared from the following raw materials in parts by weight: 2-5 parts of W type ethyl cellulose resin, 5-10 parts of organobentonite paste having an organobentonite content of 20%, 10-15 parts of 11# frit, 10-12 parts of 04# frit, 5-13 parts of M-1 frit, 5-8 parts of industrial grade barium metaborate, 1-6 parts of 400-mesh mica powder, 5-8 parts of industrial grade rubellan iron oxide, 3-11 parts of industrial grade pigment and 20-50 parts of ethanol. In an environment of 900 DEG C, the paint can achieve favorable drying property and excellent physical and chemical properties through secondary film forming of the combined frit; and meanwhile, a coating formed by the paint also has favorable self-releasing property.

Description

technical field [0001] The invention relates to a coating, in particular to a protective coating for metal heat treatment, which can achieve good drying performance and excellent physical and chemical properties through the secondary film formation of glass frit, and has good protection performance for metals treated in high temperature environments . Background technique [0002] The current metal heat treatment protective coating can effectively protect the metal during the metal heat treatment process, but the metal protection during the heat treatment process is relatively simple, either to prevent carburization, or to prevent boronization, or to prevent decarburization, or to prevent debonding. Hydrogen, etc.; In addition, after the heat treatment, some protective coatings must be sandblasted to remove the coating. The heat-treated protective coating of the present invention can effectively prevent decarburization, dehydrogenation, carburization, boronization, and hy...
