example 1

[0016] Example 1, prepare 100 grams of dry powder paint: weigh 45 grams of glass frit, 45 grams of clay, and 10 grams of talcum powder and fully disperse and mix them on a disperser, and then sieve with a 300-mesh sieve.

example 2

[0017] Example 2, prepare 100 grams of dry powder paint: weigh 50 grams of glass frit, 40 grams of clay, and 10 grams of talc powder and fully disperse and mix them on a disperser, and then sieve with a 300-mesh sieve.

example 3

[0018] Example 3, prepare 100 grams of dry powder paint: weigh 50 grams of glass frit, 45 grams of clay, and 5 grams of talcum powder and fully disperse and mix them on a disperser, and then sieve with a 300-mesh sieve.

[0019] 4. Inspection:

[0020] The inspection items are uniformity and particle size. High-temperature anti-oxidation dry powder coating products should meet the following requirements: the color should be uniform and light gray or white. Inspection method: visual inspection; particle size should be ≤ 45 mu , test method: GB1724;

[0021] 5. Packaging:

[0022] High-temperature anti-oxidation dry powder coatings are packed in inner plastic bags and outer plastic barrels to prevent moisture. Considering the convenience of use, it can be divided into 1Kg, 2Kg and other packages.

Abstract

A high temperature anti-oxidation coating is a protective coating used for inhibiting oxidation at high temperature and aims at solving the defects of comprehensive properties of present high temperature protective coatings used for stainless steel and refractory steel. A high temperature anti-oxidation dry powder coating consists of the following raw materials according to weight percentage: 45-50% of frit, 40-45% of clay and 5-10% of talcum powder. The coating has the advantages of good protection effect when being used in high heat treatment of stainless steel and refractory steel, prevention of oxidation and decarbonization at high temperature between 900-1200 DEG C; no increase of hydrogen in the process of inhibiting oxidation, no harmful effect on parts; automatic fall-off in cooling, reduction of subsequent processing procedures; and convenient coating brush application, as well as readily available raw materials.

Description

Technical field: [0001] The invention is a protective coating for anti-oxidation at high temperature. Background technique: [0002] At present, the performance of protective coatings for medium-temperature heat treatment of structural steel is relatively mature, but the comprehensive performance of high-temperature protective coatings for stainless steel and heat-resistant steel is not good, such as insufficient protection performance, self-stripping performance and coating process performance, which cannot meet production needs. Invention content: [0003] The purpose of the present invention is to provide a high-temperature anti-oxidation dry powder coating that is suitable for high-temperature heat treatment of stainless steel and heat-resistant steel; Composition in weight percent: glass frit: 45-50 clay: 40-45 talcum powder: 5-10. [0004] The advantages created by the invention: the coating has a good protective effect when used for high-temperature heat treatment...
