Abstract
A kind of graphite cast paint, following material by weight：8 11 parts of diatomite, 23 parts of lauryl sodium sulfate, soil 20 22 parts of graphite of dress, 25 parts of crystalline flake graphite, 20 25 parts of silica flour, 12 parts of lithium bentonite, 0.5 1 parts of polyvinyl butyral resin, 0.5 0.8 parts of AEO, 12 parts of binding agent.Beneficial effects of the present invention are：A kind of graphite founding materials provided by the invention, using graphite as base-material, there is good chemical stability, meanwhile, appropriate silica flour and bentonite are added, its hardness can be effectively increased, in process of production, greatly reduces the occurrence rate of scour trough.
Description
Technical field
The present invention relates to casting field, and in particular to a kind of graphite cast paint.
Background technology
Foundry facing refers to for coated in die cavity or core surface, with change its surface refractoriness, chemical stability,
The casting auxiliary material of the performances such as anti-metal erosion, anti-stick grittiness.Traditional cast paint, its chemical stability is not strong, resists
Erosion is poor, is unsuitable for large-scale industrial production.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of graphite cast paint, it is characterized in that, it by
Following raw material medicaments are made：Diatomite 8-11 parts, lauryl sodium sulfate 2-3 parts, soil dress graphite 20-22 parts, crystalline flake graphite 2-5
Part, silica flour 20-25 parts, lithium bentonite 1-2 parts, polyvinyl butyral resin 0.5-1 parts, AEO 0.5-
0.8 part, binding agent 1-2 parts.
The beneficial effects of the invention are as follows：A kind of graphite founding materials provided by the invention, using graphite as base-material, have good
Chemical stability, meanwhile, add appropriate silica flour and bentonite, its hardness, in process of production, pole can be effectively increased
The big occurrence rate for reducing scour trough.
Embodiment
Specific embodiment：A kind of graphite cast paint, it is characterized in that, it is made up of following raw material medicaments：Diatomite 8-11 parts,
Lauryl sodium sulfate 2-3 parts, soil dress graphite 20-22 parts, crystalline flake graphite 2-5 parts, silica flour 20-25 parts, lithium bentonite 1-2
Part, polyvinyl butyral resin 0.5-1 parts, AEO 0.5-0.8 parts, binding agent 1-2 parts.
The beneficial effects of the invention are as follows：A kind of graphite founding materials provided by the invention, using graphite as base-material, have good
Chemical stability, meanwhile, add appropriate silica flour and bentonite, its hardness, in process of production, pole can be effectively increased
The big occurrence rate for reducing scour trough.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
