Abstract
The invention relates to a surface brightener for an aluminum alloy foam mold and a preparation method thereof, wherein the surface brightener comprises the following components in parts by weight: 5-10 parts of isopropanol, 25-35 parts of industrial ethanol, 25-35 parts of ethyl acetate, 15-20 parts of 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, and before the special coating for the aluminum alloy lost foam is coated, the surface brightening agent is dip-coated on the foam mold, so that the surface smoothness of a casting can be improved, and the special coating for the aluminum alloy lost foam is prevented from permeating into the foam mold.
Description
Technical Field
The invention relates to a brightener and a manufacturing method thereof, in particular to a brightener for the surface of a foam mold of aluminum alloy and a manufacturing method thereof.
Background
Along with the light weight of automobiles, the market demand of aluminum alloy castings is increasing. Many cavities of automobile aluminum alloy castings are complex and are very suitable for casting by using a lost foam. But since these castings are mostly thin-walled and must withstand hydrostatic testing. When the thin-wall foam beads are formed, the complete adhesion is often difficult due to insufficient heat, so that when the coating is immersed, the coating penetrates into the gaps of the beads to cause leakage.
Disclosure of Invention
The invention aims to overcome the defect that paint permeates into a foam mould, and provides a brightening agent for the surface of an aluminum alloy foam mould and a manufacturing method thereof.
In order to achieve the purpose of the invention, the following technical scheme is adopted in the application:
the invention relates to a surface brightener for an aluminum alloy foam mold, which comprises the following components in parts by weight: 5-10 parts of isopropanol, 25-35 parts of industrial ethanol, 25-35 parts of ethyl acetate, 15-20 parts of butyl acetate, 15-25 parts of polyvinyl butyral, 35-45 parts of nitrocellulose, 1-3 parts of lacquer chips and 35-45 parts of dibutyl phthalate;
the invention relates to a surface brightener for an aluminum alloy foam mold, which comprises the following components in part by weight: 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 of lacquer flakes and 40 parts of dibutyl phthalate;
the invention relates to a method for producing a brightening agent on the surface of an aluminum alloy foam die, which comprises the following steps: it comprises the following steps:
(1) Adding 25-35 parts of industrial ethanol and 15-25 parts of polyvinyl butyral into a stirrer, and uniformly mixing;
(2) Soaking 35-45 parts of nitrocellulose by 5-10 parts of isopropanol, and then adding the nitrocellulose into the stirrer for stirring;
(3) Adding 25-35 parts of ethyl acetate, 15-20 parts of butyl acetate, 1-3 parts of paint chips and 3545 parts of dibutyl phthalate into the stirring machine for stirring, wherein the maximum circumferential tangential speed of the stirring machine is 100-300 m/min, and stirring for 20-30 min to obtain the surface brightening agent for the aluminum alloy foam mold;
the invention relates to a method for producing a brightening agent on the surface of an aluminum alloy foam die, which comprises the following steps: the maximum circumferential tangential velocity of the stirrer during step (3) was 300 m/min.
The invention designs and prepares a brightening agent for the surface of a foam mold. The mixed solvent industrial ethanol and polyvinyl butyral which do not erode the surface of the foam mould are used, and several organic matters are added into the solvent to form a surface brightening agent with certain viscosity and easily leveled surface, which is easy to gasify a closed film during casting. The coating can not invade the interior of the foam die when the coating is coated and hung. Thereby greatly reducing the leakage of the aluminum alloy casting.
