Abstract
The present invention relates to a kind of coating, specially casting sand type coating is made up of following raw material：Zircon sand, plant ash, zeolite, flyash, hydroxypropyl methyl cellulose, epoxy modified silicone resin, waterglass, Pluronic F68.The casting sand type coating that the present invention is provided, due to having used zeolite, hydroxypropyl methyl cellulose, so that paint adhesion is good, Pluronic F68 is used can be so that coating suspension performance after adding water be improved, without lasting stirring, you can uniform to brush, with the addition of waterglass and epoxy modified silicone resin can be so that surface soundness be improved, antiscour during casting molten iron, is easy to casting stripping, non-sticky sand after cooling.
Description
Technical field
The present invention relates to a kind of coating, specially casting sand type coating.
Background technology
The coating of sand casting, mainly for the interphase interaction of shielding sand mold and metal liquid, in casting
At a temperature of form density fireproof coating, place during metal liquid penetrates into sand mold, simultaneously because the material of sand mold
Decompose at high temperature and produce gas, coating can prevent from entering molten metal body weight, influence any surface finish of casting
Degree.Conventional is cold coating at present, because it is suspension liquid, and suspension is low, does not stop to stir when using
Mixing could brush uniformly, can not otherwise form the coating of densification.
The content of the invention
In order to solve the above technical problems, a kind of coating of convenient casting sand type brushed provided by the present invention,
Including following casting sand type coating, by following raw material by weight：Zircon sand 50-60 parts,
Plant ash 30-40 parts, zeolite 1-2 parts, flyash 3-5 parts, hydroxypropyl methyl cellulose 2-3 parts,
Epoxy modified silicone resin 0.3-0.8 parts, waterglass 0.1-2 parts, PULLRONIC F68 copolymerization
0.02 part of thing.
After each raw material proportionally mixes above, powder is ground into.Appropriate water is added when using.
The casting sand type coating that the present invention is provided, due to having used zeolite, hydroxypropyl methyl cellulose, makes
Paint adhesion is good, Pluronic F68 is used can be so that coating suspension after adding water
Can improve, without lasting stirring, you can uniform to brush, with the addition of waterglass and epoxy modified silicone
Resin can cause that surface soundness is improved, antiscour during casting molten iron, casting stripping is easy to after cooling, no
It is stained with sand.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiment,
The present invention will be described in further detail.
