Abstract

The invention discloses a protective coating composition for metal heat treatment. The protective coating composition is prepared from the following raw materials in parts by weight: 10 to 20 parts ofpotassium silicate, 15 to 20 parts of acrylic acid, 1 to 10 parts of alcoholic acid, 5 to 15 parts of organosilicone, 20 to 40 parts of water glass, 10 to 30 parts of polyvinyl acetate emulsion, 5 to15 parts of magnesium oxide, 1 to 10 parts of water reduction agent, 1 to 5 parts of adhesive, and 3 to 10 parts of deionized water. The protective coating composition for metal heat treatment has the advantages that the component configuration is reasonable; the temperature-resistant property is good in the metal heat treatment process, the oxidizing degree of metal is reduced, and the metal body can be well protected.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to a protective coating composition for metal heat treatment. Background technique [0002] At present, protective coatings have been applied to varying degrees in various stages of metal thermal processing (such as casting, forging, and heat treatment). And with the advancement of science and technology, the application of protective coatings in the field of metal thermal processing will become more and more extensive. The existing protective coating composition for metal heat treatment has unreasonable component configuration, and it is urgently needed for those skilled in the art to develop a new protective coating composition for metal heat treatment. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a protective coating composition for metal heat treatment. [0004] ...
