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
The present invention relates to a kind of brightener and manufacture method thereof, especially for foam mould finishing agent and the manufacture method thereof of aluminium alloy.
Background technology
Be accompanied by automotive light weight technology, the market demand of aluminium alloy castings is increasing.The many inner chambers of aluminium alloy car foundry goods are very complicated, are well suited for using lost foam casting.But because these foundry goods mostly are thin-walled and must bear the water pressure test.During the moulding of thin-walled foam beads, often be difficult to not fully bondingly because of heat, cause invading when hanging coating, coating infiltrates the bead gap and causes seepage.
Summary of the invention
The application's goal of the invention is to overcome the shortcoming that coating infiltrates the foam mould, and a kind of aluminium alloy foam mould finishing agent and manufacture method thereof are provided.
In order to finish the application's goal of the invention, the application by the following technical solutions:
A kind of aluminium alloy foam mould finishing agent of the present invention, wherein: calculate it with parts by weight and contain: the dibutyl phthalate of NC Nitroncellulose, 1-3 part coating agent which has to be dissolved in alcohol before use and 35-45 part of the butyl acetate of the industrial alcohol of the isopropyl alcohol of 5-10 part, 25-35 part, the ethyl acetate of 25-35 part, 15-20 part, the polyvinyl butyral resin of 15-25 part, 35-45 part;
A kind of aluminium alloy foam mould finishing agent of the present invention, wherein: it contains: the dibutyl phthalate of 7 parts isopropyl alcohol, 30 parts industrial alcohol, 30 parts ethyl acetate, 17 parts butyl acetate, 20 parts polyvinyl butyral resin, 40 parts NC Nitroncellulose, 2 parts of coating agents which has to be dissolved in alcohol before use and 40 parts;
A kind of method of producing aluminium alloy foam mould finishing agent of the present invention, wherein: it may further comprise the steps:
(1) it is even the polyvinyl butyral resin of the industrial alcohol of 25-35 part and 15-25 part to be joined stirrer for mixing;
(2) isopropyl alcohol of usefulness 5-10 part infiltrates the NC Nitroncellulose of 35-45 part, then, it is joined in the above-mentioned mixer stir again;
(3) again the dibutyl phthalate of the butyl acetate of the ethyl acetate of 25-35 part, 15-20 part, 1-3 part coating agent which has to be dissolved in alcohol before use and 3545 parts being joined above-mentioned mixer stirs, the largest circumference tangential velocity of mixer is 100-300 m/min, stir after 20-30 minute, namely obtained aluminium alloy foam mould finishing agent;
A kind of method of producing aluminium alloy foam mould finishing agent of the present invention, wherein: the largest circumference tangential velocity of mixer is 300 m/mins in the process of step (3).
The present invention's design has also been prepared a kind of foam mould finishing agent.Used the mixed solvent industrial alcohol and the polyvinyl butyral resin that do not corrode foam mould surface, and in this solvent, added several organic matters, formed and have the easily finishing agent of levelling of certain viscosity and surface, it easily when cast, the gasification closed film.When assurance was coated with coating, it is inner that coating can not invaded the foam mould.Thereby significantly reduce the seepage of aluminium alloy castings.
The specific embodiment
It contains a kind of aluminium alloy foam of the present invention mould finishing agent (calculating with parts by weight): the dibutyl phthalate of NC Nitroncellulose, 1-3 part coating agent which has to be dissolved in alcohol before use and 35-45 part of the butyl acetate of the industrial alcohol of the isopropyl alcohol of 5-10 part, 25-35 part, the ethyl acetate of 25-35 part, 15-20 part, the polyvinyl butyral resin of 15-25 part, 35-45 part.Preferably it contains: the dibutyl phthalate of 7 parts isopropyl alcohol, 30 parts industrial alcohol, 30 parts ethyl acetate, 17 parts butyl acetate, 20 parts polyvinyl butyral resin, 40 parts NC Nitroncellulose, 2 parts of coating agents which has to be dissolved in alcohol before use and 40 parts.
The method of a kind of aluminium alloy foam mould finishing agent of the present invention, it may further comprise the steps:
(1) it is even the polyvinyl butyral resin of the industrial alcohol of itself and 25-35 part and 15-25 part to be joined stirrer for mixing;
(2) isopropyl alcohol of usefulness 5-10 part infiltrates the NC Nitroncellulose of 35-45 part, then, it is joined in the above-mentioned mixer stir again;
(3) again the dibutyl phthalate of butyl acetate, 1-3 part coating agent which has to be dissolved in alcohol before use and 35-45 part of the ethyl acetate of 25-35 part, 15-20 part being joined above-mentioned mixer stirs, the largest circumference tangential velocity of mixer is 100-300 m/min, be preferably 300 m/mins, stir after 20-30 minute, namely obtained aluminium alloy foam mould finishing agent.
Before smearing the aluminium alloy lost foam special coating, this finishing agent dip-coating on the foam mould, can be improved the surface smoothness of foundry goods, prevent that the aluminium alloy lost foam special coating is penetrated in the foam mould.
More than describing is explanation of the invention, is not that limited range of the present invention is referring to claim to the restriction of invention, and in the situation of spirit of the present invention, the present invention can do any type of modification.
