Description
Technical field
The invention belongs to V method casting technology fields, and in particular to a kind of preparation method of V methods foundry facing.
Background technology
V method castings are vacuum sealed molding, and principle is to seal sandbox using plastic sheeting, using empty in vacuum pumped type
Gas, forms pressure differential inside and outside casting mold, makes dry sand consolidation, to form required die cavity.The casting of V methods is different from traditional sand casting maximum
Advantage is, without using adhesive, thus to alleviate sand processing work, and moulding and casting scab cleaning the amount of labour also significantly
Reduce, the old sand rate of recovery is up to more than 95%.Casting quality that V method casting techniques are produced is good, any surface finish, it is clear-cut,
Size is accurate, hardness is uniform, effectively extends the service life of casting, is praised by user, as industry new lover.V methods are cast
The use of coating is vital link in the casting of V methods.To solve the scab defect of V method casting, except reduction cast as far as possible
Temperature, selection has the molding sand of certain refractoriness and appropriate particle size distribution, rational running gate system, the fluctuation range for controlling vacuum
And ensureing effective sealing of casting mold, maximally effective approach is exactly to use V method special coatings.The quality of coating performance not only influences thin
The gasification of film and the migration of gas, also closely related with surface quality of continuous castings, coating performance is bad may to make molding sand and air
Contact and crush ahead of time.Although the every mechanical property of presently commercially available V methods foundry facing is more excellent, it there is certainly
Longer technical problem of dry time, generally requires and is carried out low temperature drying processing, but this can increase the cost of casting.
The content of the invention
In order to solve the above problems, the present invention provides a kind of preparation method of V methods foundry facing.
The present invention is achieved by the following technical solutions.
A kind of preparation method of V methods foundry facing, including following operating procedure：
（1）By mullite, zirconium silicate, calcium hydroxy phosphate, nickel protoxide according to 27-32:4-7:1:After 1 ratio mixing, according to
Mass volume ratio is 5-10:1 ratio adds deionized water thereto, is further continued for adding polycarboxylate sodium's type thereto and disperses
Agent, it is standby after being mixed evenly；
（2）By weight, by 25-35 parts of phenolic resin, 6-9 parts of tetrabutyl ammonium fluorides, 10-15 parts of frankincense gums, 3-6 parts of inclined boron
Sour barium, the heptyl ammonium bromide of 2-7 parts four, 0.5-0.7 parts of defoamer, 0.6-0.9 parts of thickener are added to 19-25 parts of absolute ethyl alcohols
In, after being mixed evenly, the step that 50-60 times of its weight is weighed is added thereto（1）The material of gained, is mixed evenly
Afterwards, V method foundry facings are made.
Specifically, above-mentioned steps（1）Middle polycarboxylate sodium's type dispersant is aqueous dispersion AMS-5040.
Specifically, above-mentioned steps（1）The Average Particle Diameters of middle mullite are 60-70 mesh, the zirconium silicate, di
Calcium, the Average Particle Diameters of nickel protoxide are 100-120 mesh.
Specifically, above-mentioned defoamer is any one in polyoxyethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether.
Specifically, above-mentioned thickener is any in methylcellulose, hydroxypropyl methyl cellulose, sodium carboxymethylcellulose
It is a kind of.
Technical scheme more than, the beneficial effects of the invention are as follows：
The V method foundry facings that the present invention is provided, it is with low cost, have good workability, dried paint film, anti-wear performance is superior,
Normal temperature strength is high, elevated temperature strength is high, and gas forming amount is few, especially fast from dry speed, its can in 2-4min quick self-drying, it is not necessary to
Using heated-air drying, the cost of equipment is reduced.Wherein, after the calcium hydroxy phosphate and nickel protoxide in the present invention act synergistically,
On the one hand every mechanical property of paint film can effectively be lifted, heat resistance, on the other hand, it can be with the film forming matter in paint film
Matter is closely combined, and is effectively reduced residual quantity of the hydrone inside paint film, is effectively prevented paint film in castings production
During produce bubble, casting is had adverse effect on；Both tetrabutyl ammonium fluoride, four heptyl ammonium bromides act synergistically
Afterwards, the uniformity of paint film can effectively be lifted so that paint film is after spraying, and the moisture on its surface can rapidly accumulate in paint film
Surface, is conducive to the rapid evaporation of moisture, and then greatly improves the speed of moisture drying.
