Abstract
The invention discloses energy-saving type water group lost mould casting paint, which comprises a fireproof material, an adhesive, a suspension agent, an auxiliary agent and water, wherein the fireproof material is a composite fireproof material and comprises bauxite, zircon flour and pagodastone in parts by weight according to the mixture ratio of 20-40:60-80:5-10. The paint comprises the following components according to the mixture ratio, by weight percent: 60-80% of composite fireproof material, 0.5-3% of adhesive, 1-2% of suspension agent, 0.5-2% of auxiliary agent and the balance of water. The paint adopts the composite fireproof material under a precondition of ensuring the fire resistance of the paint, and the consumption of resource type materials in the lost mould paint is greatly reduced; the mixture ratio of the mixed paint of the invention can induce the high-temperature encrustation of the paint, the paint is easy to strip off from a cast, the energy consumption of sand removal is reduced, and the possibility of the generation of diversified defects at the surface of the cast is also reduced by the flaky stripping of a sintered paint layer during sand removal. Moreover, the pollution action of the components of the paint to the environment is also reduced greatly by adopting the phosphate auxiliary agent.
Description
Technical field
The present invention relates to a kind of foundry facing, relate in particular to a kind of lost foam paint that is used for.
Background technology
Existing lost foam paint all is to rely on its refractory powder physics and chemical inertness at high temperature to produce anti-scab effect, pursues high refractoriness material, so the refractory material selection is more single.Can not peel off in flakes when having the lost foam paint sand removal now, cause cast(ing) surface to have the diversity defective easily.
Summary of the invention
Technical problem to be solved by this invention provide help more behind a kind of sintering with peel off gradually, save the water group lost mould casting paint of cost more.
For solving the problems of the technologies described above, technical scheme provided by the invention is as follows:
A kind of energy-saving type water group lost mould casting paint is made up of refractory material, binding agent, suspending agent, auxiliary agent and water,
Described refractory material is a composite refractory, comprise bauxite, zirconium English powder, pyrophillite, and its weight portion mixing ratio is: 20～40: 60～80: 5～10.
The percentage by weight proportioning of described coating is:
Composite refractory 60～80%, binding agent 0.5～3%, suspending agent 1～2%, sodium dihydrogen phosphate 0.5～2%, all the other components are water.
Described auxiliary agent is a sodium dihydrogen phosphate.Described suspending agent is selected sodium bentonite or lithium bentonite for use.
Described binding agent is an industrial metasilicate.
Coating of the present invention has significantly reduced the consumption of resource-type material in the lost foam paint guaranteeing to select composite refractory for use under the coating refractoriness prerequisite; Its compo proportioning can be impelled coating high temperature crust, easily peel off with foundry goods, reduces the sand removal energy consumption, and peeling off in flakes of sintering dope layer also reduced cast(ing) surface diversity defective and produced possibility during sand removal simultaneously.
And the adding of sodium dihydrogen phosphate has improved the stability of coating and intensity at high temperature.Simultaneously, contain multiple organic additive in the component of existing lost foam paint, the gas forming amount that had both increased coating causes casting flaw, also environment is polluted.And prioritization scheme of the present invention is not selected organic additive for use, rely on the characteristic of composite fire aggregate itself,, low with soluble phosphate as its gas forming amount of inorganic matter as coating additive, toxicity and environmental pollution are little, have significantly reduced the contamination of coating composition to environment.
Description of drawings
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Fig. 1 is the preparation section schematic diagram of energy-saving type water group lost mould casting paint of the present invention.
The specific embodiment
Fig. 1 shows the preparation process of energy-saving type water group lost mould casting paint of the present invention.
Energy-saving type water group lost mould casting paint of the present invention is made up of refractory material, binding agent, suspending agent, auxiliary agent and water,
Described refractory material is a composite refractory, comprise bauxite, zirconium English powder, pyrophillite, and its weight portion mixing ratio is: 20～40: 60～80: 5～10;
The percentage by weight proportioning of described coating is:
Composite refractory 60～80%, binding agent 0.5～3%, suspending agent 1～2%, auxiliary agent 0.5～2%, all the other components are water.
1. at first according to the form below is prepared composite refractory:
| Embodiment | Bauxite (kg) | Zirconium English powder (kg) | Pyrophillite (kg) |
| ??1 | ??20 | ??70 | ??5 |
| ??2 | ??24 | ??80 | ??6 |
| ??3 | ??30 | ??75 | ??8 |
| ??4 | ??35 | ??65 | ??7 |
| ??5 | ??40 | ??60 | ??10 |
Prepare water base lost foam paint according to the proportioning of following table:
Wherein binding agent is selected industrial metasilicate for use, and suspending agent is selected for use and is sodium bentonite or lithium bentonite, selection of auxiliary sodium dihydrogen phosphate.
| Embodiment | Composite refractory % | Binding agent % | Suspending agent % | Auxiliary agent % | Water |
| ??1 | ??60 | ??2.5 | (1.8 sodium base) | ??0.9 | All the other |
| ??2 | ??65 | ??0.5 | 1 (sodium base) | ??0.5 | All the other |
| ??3 | ??70 | ??1.5 | (1.5 sodium base) | ??1 | All the other |
| ??4 | ??75 | ??2 | (1.3 lithium base) | ??1.5 | All the other |
| ??5 | ??80 | ??3 | 2 (lithium bases) | ??2 | All the other |
Above-mentioned binding agent also can be selected Ludox or other conventional binding agent for use,
The proportioning of above-mentioned composite refractory and auxiliary material also can adopt other conventional proportioning forms.
2. Weighting and Controlling
Take by weighing each component raw material of coating by the proportioning consumption.
3. mix and stir
Note when reinforced earlier water and suspending agent, binding agent and auxiliary agent being sequentially added into, need control speed of agitator and mixing time.Add composite refractory after mixing again gradually; Water and suspending agent are adjusted item for can be used as, and suitably adjust according to actual conditions;
Single batch of output is below 1 ton, and speed of agitator is controlled at: 750-1350 rev/min, the total mixing time behind reinforced the finishing must not be lower than 30min;
4. carry out the performance test of coating, can adjust again, stir as undesirable;
5. finished product is put in storage.
By the water group lost mould casting paint that makes in the foregoing description, the mold technique steel-casting that is applied to disappear, coating have high strength, good anti-scab effect, reduce the cleaning energy consumption, guarantee that in energy-conservation the steel casting surface quality is greatly improved.
