Description
Technical field
The present invention relates to a kind of having concurrently and do alcohol-base foundry coating and the production technology thereof that wet deixis and sintering are peeled off function.
Background technology
Sand casting accounts for 70% of foundry goods total amount in the Foundry Production, and sand casting coating can significantly improve the fineness of cast(ing) surface, prevents foundry goods scab, thereby application surface is very wide.
At present, the used coating of sand casting is main with alcohol-base paint still, the alcohol-base foundry coating advantage: 1, brushing is lighted just and can be formed strength of coating preferably; 2, easy to use, with short production cycle.The conventional cast alcohol-base paint carries out drying dehumidification and promotes the coating sclerosis with the method for ignition usually, but can't recognize directly whether it parches fully after the burning, and the dried coating of burning whether the moisture absorption also can't directly be judged after placing a period of time.If dope layer does not fully get damp after drying or the drying, at this moment be used for Foundry Production, then coating is easy to peel off because of the moisture absorption undercapacity, and foundry goods will produce major defects such as pore, slag inclusion, surface quality be bad during the casting molten iron.Therefore, if can find before the cast of sand mold, core group case that dope layer does not parch or the dry back moisture absorption, so just can remedy and can not cause foundry goods generation defective through the mode of baking dehumidifying again.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, and providing a kind of can judge that coating is whether dry and have the alcohol-base foundry coating that sintering is peeled off function through color.The present invention also provides the production technology of this alcohol-base foundry coating, utilizes this production technology to make to have concurrently to do the alcohol-base foundry coating that wet deixis and sintering are peeled off function.
The present invention is a kind of to be had concurrently and do wet deixis and sintering and peel off the technical scheme that alcohol-base foundry coating adopted of function and be: the present invention is a raw material with refractory material, suspending agent, agglutinant, binding agent, indicator, industrial alcohol and isopropyl alcohol; Said refractory material is by weight ratio: mullite powder 40% ~ 50%; Alumine powder 30% ~ 40%, silica flour 20% ~ 30%; Other composition by accounting for said properties of refractories percentage is:
Suspending agent: hectorite powder 1% ~ 3%, attapulgite powder 1% ~ 3%;
Agglutinant: 5% ~ 10%;
Binding agent: novolac resin 1% ~ 2%, rosin 0.5% ~ 1.5%;
Indicator: bromocresol green 0.1% ~ 0.5%;
Industrial alcohol: 30% ~ 40%;

Said bromocresol green is the chemical pure bromocresol green.
Said agglutinant is selected from diatomite in powder, potassium albite in powder or refractoriness in a kind of of 1000 ℃～1100 ℃ fire clay or more than one combination.
The granularity of said diatomite in powder >=320 orders.
A kind of having concurrently of the present invention done wet deixis and sintering and peeled off the technical scheme that technology adopted of the alcohol-base foundry coating of function and be: this production technology may further comprise the steps:
(1) earlier with hectorite powder, attapulgite powder water moistening after, add industrial alcohol, isopropyl alcohol again, in homogenizer, stir then;
(2) add quartz sand powder, alumine powder, mullite powder and agglutinant, in homogenizer, stir;
(3) add phenolic resins, rosin liquid and bromocresol green, in homogenizer, stir;
(4) grind a discharging with colloid mill, packing.
The invention has the beneficial effects as follows: because the present invention adopts the variable color indication to do the mode of tide; Comprise refractory material, suspending agent, agglutinant, binding agent, bromocresol green, industrial alcohol and isopropyl alcohol; When behind the coating point fire burns during bone dry, coating surface shows faint yellow; When if coating does not have completing combustion dry, do not having the dry place of completing combustion to show green sky blue, and color is dark more, then moist more; After coating point fire burns drying, place a period of time, coating surface can make moist, and show green sky blue at the place of making moist, and color is dark more, and it is more severe to make moist, and the place of making moist does not show faint yellow; The present invention makes behind the casting molten iron dope layer sinter into to be prone to peel off the sinter layer in foundry goods through adding agglutinant in addition; So the present invention has concurrently to do the alcohol-base paint that wet indication and sintering are peeled off function; And have anti-stick preferably grittiness can; The present invention can in time indicate dried tide and the make moist degree Presentation Function of the coating after the ignition after placing a period of time after the coating surface burning, and casting back coating forms peel ply, so be specially adapted in the production of high humility and big foundry goods.
In addition; The present invention is used to make described a kind of having concurrently and does wet deixis and sintering to peel off the production technology of the alcohol-base foundry coating of function be a kind of convenient and simple technology; This prepared is simple, easy to operate, abundant raw materials and production cost are low, is mainly used in to produce described a kind of having concurrently and do the alcohol-base foundry coating that wet deixis and sintering are peeled off function.
