Description
Technical field
The present invention relates to evaporative pattern technical fields more particularly to a kind of lost foam paint and preparation method thereof.
Background technique
Lost foam casting is the cavityless casting that foam mould uses bindless dry sand combination vacuum pumping technology.The country is main
The call wanted has " dry sand cavityless casting ", " vacuum full mold casting ", abbreviation EPC casting；External call mainly has: Lost
Foam Process (U.S.A), P0licastProcess (Italy) etc..Lost foam casting is current casting state-of-the-art in the world
One of technique is made, primary " revolution " being known as in casting history is referred to as 21 century Green foundry both at home and abroad.
Traditional lost foam paint is in order to improve the refractoriness of coating, and refractory aggregate largely uses silica flour, and feature is valence
For the cheap refractoriness height of lattice up to 1750 DEG C, low temperature intensity is high.The disadvantage is that silica flour has phase transformation, volume meeting at 575 DEG C
Increase suddenly.The defects of be easy to causeing flame retardant coating to crack, casting caused to generate burnt-in sand, overlap, crush.Another disadvantage is that thoroughly
Gas performance is poor, no adsorptivity.Most of lost foam casting factory is caused to form nowadays dry in order to increase aeration raising
The granularity of sand.The granularity of dry sand is improved, coating intensity increases again, causes coating layer thickness excessive.Paint thickness increases
Gas permeability is again bad, increases vacuum degree again, forms a poor circulation.Eventually lead to surface roughness height, defect
The appearance for the series of malpractice such as more, yellow area's foam circulation time is long, takes up a large area, and drying chamber mostly energy consumption is big.
Traditional lost foam paint generally uses starch as suspending agent and bonding agent, and feature is cheap suspendability
It is good.The disadvantage is that no thixotropy, the inefficiency that the weak easy drip of adhesive ability causes Bai Mo to hang painting (generally requires and is coated with 3~4
All over) and complicated bubbles model cannot be coated with.Cause variety of moduli weight big due to applying thickness (generally in 1.5~3mm), manually
When being coated with, large labor intensity, foam mold is easy to damage, it is therefore desirable to be divided into smallclothes to be coated with one by one bubbles model, lead to week
It is long to turn the time, and drying chamber quantity is more, and energy consumption is high.The workload of bonding process is increased, and the precision of bonding also proposed very high
It is required that.Another disadvantage is that fermentation is easy when heat in day, gives out acid smell since starch is organic matter.After fermenting simultaneously
Coating suspension performance and adhesive property reduce, and even fail when serious.In order to avoid coating fermentation, can generally be added in coating
The preservatives such as benzoic acid.Long Term Contact may cause adverse effect to human health.
Summary of the invention
Technical problem to be solved by the present invention lies in the low and high temperature for the lost foam paint for how improving the prior art is strong

Misrun at angle.If it is also feasible for being produced in batches using this coating, exactly by being optimized in pouring technology come real
It is existing.But we are the comparative illustrations for passing through embodiment 1 and comparative example 2 in the identical situation of pouring technology here, are being poured
Since running channel proximal end has endlessly, fresh high temperature molten aluminum enters in journey, the good fluidity fltting speed of aluminum water quickly,
But distal end aluminum water temperature gradually decreases, the mobility of aluminum water is deteriorated and also to overcome resistance of the foam in cracking, causes
Running channel proximal end liquid level is high, and running channel distal end liquid level is low, and in casting, cast-internal is formed one and inclined fills type liquid in this way
Bit line.Therefore when coating other performance is identical be coating adsorptivity it is bad in the case where running channel proximal end aluminum water due to temperature
Spend height can by this part foam liquid lysate gasify be discharged, it is some do not come and gasify with not by the foam of paint-absorbable
Lysate just as liquid stream is to distal collection, has no ability to finally inhale so overbrushing material since the aluminum water temperature of distal end is low
Attached foam liquefied substance gasification.The important of paint-absorbable performance can be found out from the two comparisons.
Using the lost foam paint of comparative example 3, the effect of foam mold moulding by casting is less desirable.By according to the analysis, applying
Expect that thermal insulation property is bad along with permeability is high, causes aluminum water cooling rate too fast.Especially into first strand of aluminium of casting
Water, due to the route trip longest that it is walked, and not fresh hot aluminum water is supplemented, and there are no go to foam mold after entering casting
End forms reflux and carrys out additional heat, with regard to rapid cooled and solidified.It is subsequent slowly increased into the aluminum water temperature of casting backward after
It fills type effect or good still overall effect is less desirable.
Using the lost foam paint of comparative example 4, the effect of foam mold moulding by casting is undesirable.Thermal-insulation coating performance is breathed freely
Performance and absorption property are all poor, and the place for only having aluminum water temperature high when filling type can fill type, but it can be seen that have apparent cold
Every.The low place of temperature occurs as soon as large area misrun.
It can be seen that thermal insulation property, permeability and the absorption property in aluminium alloy lost foam cast paint by experiment
Importance.
In conclusion the present invention with the refractory aggregate mullite through stomata and controls mullite grain by control addition
Diameter distributed area controls gas permeability.It if gas permeability is excessively high, will lead to aluminum liquid filling type excessive velocities, volume gas slag etc. caused to lack
It falls into.The defects of if gas permeability is too low, it is excessively slow to will lead to aluminum liquid filling type speed, causes misrun, cold shut, stomata.
The present invention controls adsorptivity by adding the diatomite with more penetrability stomatas.Since aluminium alloy is poured temperature
Low about 750~760 DEG C are spent, polystyrene foam plastics can largely liquefy, a part gasification.Therefore coating needs to have good
Adsorptivity, liquefied substance is adsorbed to the gas hole defect for avoiding that liquefied substance wrapped folder into molten aluminum, is formed to disperse in time.
Mullite and diatomite in the present invention have the stomata of perforation, therefore thermal insulation property is all very good.So logical
Both materials are crossed to solve the problems, such as heat preservation.Since aluminium alloy pouring temperature is low, the small-sized casting of heavy wall is unobvious, especially in
Heavy castings or thin wall type casting when thermal-insulation coating performance is bad, are easy to appear cold shut and misrun defect.
The thixotropy of coating of the present invention be by attapulgite in stirring the cotton-shaped variation that generates realize and with carboxylic first
The suspendability of base cellulose combines the phenomenon that layering occur.For being poured the aluminium alloy casting of thin-wall complicated part
Part, especially casting thinnest part only have 3.5~4mm, there was only the gap 10mm at interlayer minimum.Also, a casting has multiple
Interlayer and functional areas, cavity structure are complicated, and by the oil duct of cast-internal, water channel, air flue and some fabrication holes plus
Strengthening tendons etc. pass through pouring one-step forming.Therefore it needs coating to have and good is coated with performance.Measure the quality master that coating is coated with performance
If thixotropy.In order to obtain with the lubricious of high-quality appearance, in coating use or in the mistake of coating dried/cured
Cheng Zhong needs to keep its sufficient horizontality, to avoid flowing down problems while reducing the generation of coating irregular surface
