Abstract

The invention belongs to the field of hub machining, and particularly discloses a releasing agent for casting. The releasing agent is composed, by mass percent, 8%-17% of sodium borate, 5%-7% of silicon dioxide, 20%-35% of ground glass, 7%-19% of a fluorinated surfactant, 1%-5% of polyvinyl alcohol, 7%-20% of sodium dodecyl benzene sulfonate and the balance silicon oil. The aim of the releasing agent is achieved better, the preparing technology is simple, the mold releasing effect is good, the concrete surface is clean, the cost is low, operation is convenient, the releasing agent is nonflammable and does not pollute the environment, the rustproof effect on an aluminum alloy template and a steel template can be further played, and the self-curing capacity of the concrete surface is improved.

Description

technical field [0001] The invention belongs to the field of hub processing, in particular to a mold release agent for casting. Background technique [0002] Casting is one of the basic processes of the modern device manufacturing industry. It is a process in which metals are smelted into liquids that meet certain requirements and poured into molds. After cooling, solidification, and cleaning, castings with predetermined shapes, sizes, and properties are obtained. . Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. However, casting demoulding is an important step in the casting process, which is directly related to the quality of casting. Therefore, a mold release agent is commonly used in the casting process. A mold release agent is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make the surface...
