Abstract
The invention discloses a kind of casting sand type coating, by following raw material by weight：The parts by weight of zirconium English powder 55 60, the parts by weight of graphite powder 10 20, the parts by weight of magnesite emery dust 10 20, the parts by weight of organobentonite 25, the parts by weight of isopropanol 23, the parts by weight of polyurethane resin 0.5 1, the parts by weight of waterglass 12, the parts by weight of cryolite powder 0.2 0.8；Magnesite emery dust used, can more effectively avoid the interaction between molten steel/silica sand in casting sand type coating of the present invention, after cooling, be easy to casting stripping, and surface roughness are preferable；Binding agent polyurethane resin used has good heat-resisting quantity, and has certain corrosion resistance, and coating is not easily stripped；Cryolite powder used（Na3AIF6）Active NaF, AIF3 etc. are formed at high temperature, and the carbon decomposited to sand mold produces suction-operated, is allowed to not be deposited in cast(ing) surface, prevents cast(ing) surface carbon distribution or scab from producing.
Description
Technical field
The present invention relates to technical field of coatings, specifically a kind of casting sand type coating.
Background technology
The coating of sand casting, mainly for interpenetrating effect between protection sand mold and metal liquid, in casting temperature
Density fireproof coating is formed under degree, simultaneously because the material of sand mold decomposes generation gas at high temperature, coating can prevent from entering
Molten metal body weight, the surface roughness of casting is influenceed, the binding agent commonly used in cast paint is mainly waterglass, due to waterglass
It is cheap, it is easy to use, but when casting more high-accuracy for temperature, coating easily peels off, and the surface roughness of casting is poor,
And cast(ing) surface adheres to one layer of scab being difficult to clean off, increase process costs.
The content of the invention
It is an object of the invention to provide a kind of casting sand type coating, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：
A kind of casting sand type coating, by following raw material by weight：Zirconium English powder 55-60 parts by weight, graphite powder 10-
20 parts by weight, magnesite emery dust 10-20 parts by weight, organobentonite 2-5 parts by weight, isopropanol 2-3 parts by weight, polyurethane resin
0.5-1 parts by weight, waterglass 1-2 parts by weight, cryolite powder 0.2-0.8 parts by weight；
As the further scheme of the present invention：The casting sand type is preferably that following preparation method obtains with coating：
S1, by the parts by weight of zirconium English powder 55, the parts by weight of graphite powder 15, the parts by weight of magnesite emery dust 20, the parts by weight of organobentonite 5,
The parts by weight of cryolite powder 0.5 are ground in grinder；
After S2, grinding, added in grounds travel by material water volume ratio 1:10 water, sequentially add the parts by weight of isopropanol 3, poly- ammonia
The parts by weight of ester resin 0.5, the parts by weight of waterglass 1, carry out centrifugal mixer.
After S3, coating make, uniformly sand mold is brushed, or spraying, coated and dried is carried out in the baker of constant temperature, is followed
Ring is in triplicate.
As the further scheme of the present invention：The centrifugal mixer condition is 1500r/min, time 30min.
As the further scheme of the present invention：The temperature range of the coated and dried constant temperature be 40 DEG C -60 DEG C, preferably 50
℃。
Compared with prior art, the beneficial effects of the invention are as follows：Magnesite used in casting sand type coating of the present invention
Emery dust, the interaction between molten steel/silica sand can be more effectively avoided, after cooling, be easy to casting stripping, and cast(ing) surface is thick
Rugosity is preferable；Binding agent polyurethane resin used has good heat-resisting quantity, and has certain corrosion resistance, and coating is not easy
Peel off；Cryolite powder used（Na3AIF6）Active NaF, AIF3 etc. are formed at high temperature, and the carbon decomposited to sand mold produces absorption
Effect, is allowed to not be deposited in cast(ing) surface, prevents cast(ing) surface carbon distribution or scab from producing.
