Abstract
The invention discloses a water-based zircon powder quick drying paint for an ultra-large steel casting. The paint consists of refractory material, binder, suspending agent and water, wherein the refractory material is zircon powder; the paint also contains high-purity magnesium oxide, the MgO content of which is more than 99 percent; and the paint comprises the following components in percentage by weight: 70 to 83 percent of zircon powder, 2 to 3.5 percent of binder, 1 to 2.5 percent of suspending agent, 0.1 to 0.5 percent of high-purity magnesium oxide and the balance of water, wherein the binder is vinyl acetate/acrylic emulsion and the suspending agent is lithium-based bentonite. The paint can effectively promote moisture migration on the surface of the paint by adding a reasonable amount of magnesium oxide aid so that the paint can quicken the curing speed, the next coating of the paint can be performed without drying the paint in short time, the production process is simplified, the resource is saved and the energy consumption is reduced.
Description
Technical field
The present invention relates to a kind of foundry facing, relate in particular to a kind of coating that is applicable to heavy castings.
Background technology
Existing ultra-large type steel-casting often use alcohol-base paint in process of production, but the alcohol-base paint security is not enough, easily has an accident.
And be used in the water based paint of ultra-large type steel-casting, though security is better than alcohol-base paint, curing rate is slower, just can apply second layer coating after must the per pass coating drying respectively, increases production process and energy waste greatly, extends manufacture cycle.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water based paint with quick-drying function, after this coating brushing, need not oven dry within a short period of time, and the surface has certain intensity, can continue to go up second layer coating.
For solving the problems of the technologies described above, technical scheme provided by the invention is as follows:
A kind of water-based zircon powder quick drying paint for ultra-large steel casting, be made up of refractory material, binding agent, suspending agent and water, described refractory material is a zirconium English powder, also includes MgO content greater than 99% high-purity magnesium oxide in this coating, each component weight percent content of this coating is as follows
Zirconium English powder 70～83%, binding agent 2～3.5%, suspending agent 1～2.5%, high-purity magnesium oxide 0.1～0.5%, all the other are water,
Described binding agent is an acrylate and vinyl acetate emulsion, and described suspending agent is a lithium bentonite.
Coating of the present invention selects for use zirconium English powder as refractory material, guarantees the high refractoriness and the heat storage capacity of coating; Advance a large amount of Test Summaries, added the auxiliary agent magnesia of reasonable amount, and just can promote the coating surface migration of water very effectively, make coating can accelerate curing rate, need not dry in the short period, just can carry out next coating all over coating, simplify production process, economize on resources, reduce energy consumption.
Obtain the reagent of selecting for use of best bond agent, suspending agent through a large amount of tests, and each best reagent proportioning of acquisition, by the quick drying paint that zirconium English powder 70～83%, acrylate and vinyl acetate emulsion 2～3.5%, lithium bentonite 1～2.5%, high-purity magnesium oxide 0.1～0.5%, all the other water are formed, can obtain best synthesis coating performance and quick-drying energy.
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 water base zirconium English powder quick drying paint of the present invention.
The specific embodiment
Fig. 1 shows the preparation process of water base zirconium English powder quick drying paint of the present invention.
Obtain best serviceability, be coated with the water base zirconium English powder quick drying paint that is applicable to the ultra-large type steel-casting of hanging performance, quick-drying energy through a large amount of tests, its percentage by weight proportioning is:
Zirconium English powder 70～83%, acrylate and vinyl acetate emulsion 2～3.5%, lithium bentonite 1～2.5%, high-purity magnesium oxide (MgO content is greater than 99%) 0.1～0.5%, all the other are water.
1. at first according to the form below is prepared composite refractory:
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 lithium bentonite (suspending agent), acrylate and vinyl acetate emulsion (binding agent) and high-purity magnesium oxide (auxiliary agent) being sequentially added into, need control speed of agitator and mixing time.Add refractory material zirconium English powder after mixing again gradually; Water and lithium bentonite 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 30 minutes;
4. carry out the performance test of coating, can adjust again, stir as undesirable;
5. finished product is put in storage.
By the water-based zircon powder quick drying paint for ultra-large steel casting that makes in the foregoing description, when being applied to the ultra-large type Steel Castings, coating has excellent comprehensive performances, and paint solidification speed is obviously accelerated, need not dry in short period, just can carry out next coating, simplify production process, economize on resources, reduce energy consumption all over coating.
Claims (1)
1. water-based zircon powder quick drying paint for ultra-large steel casting, form by refractory material, binding agent, suspending agent and water, it is characterized in that: described refractory material is a zirconium English powder, in this coating, also include MgO content greater than 99% high-purity magnesium oxide, each component weight percent content of this coating is as follows
