Anti-sulfurizing coating

Abstract

The invention discloses anti-sulfurizing coating and belongs to the technical field of coating design. The anti-sulfurizing coating is composed of following components of, by mass, 100% of zircon powder, 0.2% of vegetable glue, 1% of modified clay, 1.6% of bakelite, 26% of water, 0.1% of a dispersing agent, 0.03% of a surface active agent, 0.3% of a thickening agent, 0.3% of a penetrant, 0.08% of a defoaming agent, 0.2% of a preservative and an anti-sulfurizing agent. The anti-sulfurizing coating disclosed by the invention is low in production cost, high in operability, reliable in performance and remarkable in anti-sulfurizing effect and crack prevention effect, and the workloads of cleaning, soldering and polishing are greatly lowered.

Description

technical field

[0001] The invention relates to the technical field of coating design, in particular to an anti-sulfur coating. Background technique

[0002] In recent years, with the development of casting technology, the role of casting coatings in casting production has been paid more and more attention by domestic foundry enterprises. Facing the development of new international casting technologies, domestic coating products often cannot meet the requirements of these new technologies , while foreign products are several times the domestic price. This undoubtedly increases the casting cost for the enterprise. Therefore, the study of casting coatings suitable for new technologies has become one of the most important tasks of the current foundry industry. At present, most domestic cast iron manufacturers use graphite coatings, and some manufacturers also use light-colored coatings. Although graphite coating has high refractoriness and is easy to brush, it pollutes the e...
