Embodiment Construction

[0013] An aluminum alloy foam mold surface brightener (calculated in parts by weight) of the present invention contains: 5-10 parts of isopropanol, 25-35 parts of industrial ethanol, 25-35 parts of ethyl acetate, 15-20 parts butyl acetate, 15-25 parts of polyvinyl butyral, 35-45 parts of nitrocellulose, 1-3 parts of lacquer flakes and 35-45 parts of dibutyl phthalate. Preferably it contains: 7 parts of isopropanol, 30 parts of industrial ethanol, 30 parts of ethyl acetate, 17 parts of butyl acetate, 20 parts of polyvinyl butyral, 40 parts of nitrocellulose, 2 parts lacquer flakes and 40 parts dibutyl phthalate.

[0014] A kind of method of aluminum alloy foam mold surface brightener of the present invention, it comprises the following steps:

[0015] (1) Add it with 25-35 parts of industrial ethanol and 15-25 parts of polyvinyl butyral into the mixer and mix evenly;

[0016] (2) Soak 35-45 parts of nitrocellulose with 5-10 parts of isopropanol, and then add it to the above m...

Abstract

The invention relates to a surface brightening agent for an aluminum alloy foam mold and a manufacturing method of the surface brightening agent. The surface brightening agent comprises the following components in parts by weight: 5-10 parts of isopropanol, 25-35 parts of industrial alcohol, 25-35 parts of ethyl acetate, 15-20 parts of butyl acetate, 15-25 parts of polyvinyl butyral, 35-45 parts of cellulose nitrate, 1-3 parts of paint and 35-45 parts of dibutyl phthalate. The surface brightening agent is coated on the foam mold before a special coating for an aluminum alloy lost mold is coated; the surface smoothness of a casting can be improved; and the special coating for the aluminum alloy lost mold is prevented from penetrating into the foam mold.

Description

technical field [0001] The invention relates to a brightener and a manufacturing method thereof, in particular to a foam mold surface brightener for aluminum alloys and a manufacturing method thereof. Background technique [0002] With the lightweight of automobiles, the market demand for aluminum alloy castings is increasing. Many inner cavities of automotive aluminum alloy castings are very complex, which is very suitable for lost foam casting. However, since these castings are mostly thin-walled and must withstand hydrostatic tests. When thin-walled foam beads are formed, it is often difficult to fully bond due to insufficient heat, which causes the paint to penetrate into the gaps between the beads and cause leakage when the paint is infiltrated. Contents of the invention [0003] The purpose of the invention of the present application is to overcome the shortcoming that the paint penetrates into the foam mold, and provide a surface brightener for an aluminum alloy f...
