Abstract
The invention discloses one kind for aluminium alloy casting metal coating, it is made of following raw material according to parts by weight：40 60 parts of 30 40 parts of attapulgite, 10 20 parts of ethylene vinyl acetate, 13 parts of adhesion promoter, 8 10 parts of phenolic resin, 0.8 1.0 parts of sodium alginate, 12 parts of neopelex, 3.5 4.0 parts of Ludox and environmentally friendly solvent.Of the invention a kind of for aluminium alloy casting metal coating, not only crocking resistance is strong, but also adhesiveness is good, not easily to fall off, and coating long-time service will not blister, be cracked, whiten or even the problems such as delamination.
Description
Technical field
It is specifically a kind of to be used for aluminium alloy casting metal coating the present invention relates to mechanical manufacturing field.
Background technology
As structural material, compared with steel, aluminium alloy has many advantages, such as that density is small, and specific strength is high, Aeronautics and Astronautics,
The fields such as automobile, medical instrument dosage increasingly increases.In aluminium alloy castings production process, especially with porose aluminium alloy
In casting manufacturing process, a large amount of hole defect can be generated near pore structure, causes aluminium alloy castings performance especially mechanical property
It can decline to a great extent with sealing performance, cause yield rate low, mass energy waste to production brings loss.For in aluminium alloy
Hole defect research already become casting aluminum alloy research hotspot, but never effectively process with
Control or eliminate such hole defect.
Invention content
The purpose of the present invention is to provide one kind for aluminium alloy casting metal coating, above-mentioned technological deficiency is solved.
To achieve the above object, the present invention provides following technical solution：
One kind is made of following raw material for aluminium alloy casting metal coating according to parts by weight：30-40 parts of attapulgite, ethylene-
10-20 parts of vinylacetate, 1-3 parts of adhesion promoter, 8-10 parts of phenolic resin, 0.8-1.0 parts of sodium alginate, dodecyl
40-60 parts of 1-2 parts of benzene sulfonic acid sodium salt, 3.5-4.0 parts of Ludox and environmentally friendly solvent.
It is above-mentioned a kind of for aluminium alloy casting metal coating, it is made of following raw material according to parts by weight：Attapulgite 30-38
Part, 10-18 parts of ethylene-vinyl acetate, 1-2 parts of adhesion promoter, 8-9 parts of phenolic resin, 0.8-0.9 parts of sodium alginate,
40-58 parts of 1-1.8 parts of neopelex, 3.5-3.8 parts of Ludox and environmentally friendly solvent.
It is above-mentioned a kind of for aluminium alloy casting metal coating, it is made of following raw material according to parts by weight：35 parts of attapulgite,
15 parts of ethylene-vinyl acetate, 2 parts of adhesion promoter, 9 parts of phenolic resin, 0.9 part of sodium alginate, dodecyl benzene sulfonic acid
