Abstract
The invention discloses a zircon powder coating which is characterized by comprising the following components in percentage by weight: 52 percent to 58 percent of zircon powder; 1.2 percent to 1.7 percent of titanium dioxide, 1.2 percent to 1.7 percent of lithium-base bentonite, 1.2 percent to 1.7 percent of attapulgite, 0.51 percent to 0.6 percent of butyral resin, 0.68 percent to 0.88 percent of white dextrins, 0.51 percent to 0.6 percent of white latex, 32.5 percent to 35.6 percent of methanol and 4.2 percent to 5.22 percent of ethanol. The invention also discloses a preparation method of the zircon powder coating. The zircon powder coating and the preparation method thereof have the advantage that the zircon powder coating prepared from the components has the advantages of high strength, high adsorbing speed, strong adhesive force, good collapsibility and the like. A casting cast by the coating has the characteristics of smooth runner and smooth surface.
Description
Technical field
The present invention relates to a kind of zircon flour coating and manufacturing approach thereof; Being specifically related to a kind of is primary raw material with zirconium English powder, makes the zircon flour coating of advantages such as having the intensity height, absorb fast, strong adhesion, collapsibility is good.The invention still further relates to the preparation method of this coating.
Background technology
When zircon flour coating in the market uses on foundry goods or loam core, because its prescription is unreasonable, defectives such as appearance is rough, the disconnected core in loam core sintering, cast(ing) surface pore appear and through regular meeting.Make that the product percent of pass that is suitable for is low.
Summary of the invention
Main task of the present invention is to provide a kind of zircon flour coating, specifically be a kind ofly have the intensity height, absorb fast, strong adhesion, zircon flour coating that collapsibility is good.
In order to solve above technical problem, a kind of zircon flour coating of the present invention is characterized in that being made up of by following percentage by weight following component: zirconium English powder: 52%-58%; Titanium white powder: 1.2%-1.7%; Lithium bentonite: 1.2%-1.7%; Attapulgite: 1.2%-1.7%; Butyral resin: 0.51%-0.6%; White dextrin: 0.68%-0.88%; White glue with vinyl: 0.51%-0.6%; Methyl alcohol: 32.5%-35.6%; Ethanol: 4.2%-5.22%.
The present invention also provides a kind of method of making zircon flour coating, it is characterized in that step is following: the first step: butyral resin is dissolved in 20% the methyl alcohol dilute solution of aforementioned proportion, left standstill 12 hours; Second step: the speed that zirconium English powder, titanium white powder, lithium bentonite, attapulgite, white dextrin are knocked down in the mixer with 880 rev/mins stirred 15-25 minute, and is mixed to fully; The 3rd step: the mixed solution and the ethanol of first step gained are poured in the mixer, after one hour, mixer is decelerated to 880 rev/mins with 1450 rev/mins speed stirrings; Pour white glue with vinyl into; Stirred 45 minutes with 1450 rev/mins speed again, observe the coating top layer, when the coating top layer evenly, when fine and smooth, smooth; Pour remaining 80% methyl alcohol into mixer again, stir and get zircon flour coating after 15 minutes.
Advantages such as the invention has the advantages that: this coating is suitable for loam core, the shell of the whole banked direction control valves foundry goods in large-scale, multithread road, and this coating has the intensity height, it is fast to absorb, strong adhesion, collapsibility are good.The foundry goods runner that uses this coating to cast is smooth, cast(ing) surface is smooth.
The specific embodiment
It is subsequent use to choose following components in part by weight: zirconium English powder: 52%-58%; Titanium white powder: 1.2%-1.7%; Lithium bentonite: 1.2%-1.7%; Attapulgite: 1.2%-1.7%; Butyral resin: 0.51%-0.6%; White dextrin: 0.68%-0.88%; White glue with vinyl: 0.51%-0.6%; Methyl alcohol: 32.5%-35.6%; Ethanol: 4.2%-5.22%.
Said components prepared according to the following steps form final zircon flour coating, the first step: butyral resin is dissolved in 20% the methyl alcohol dilute solution of aforementioned proportion, left standstill 12 hours; Second step: the speed that zirconium English powder, titanium white powder, lithium bentonite, attapulgite, white dextrin are knocked down in the mixer with 880 rev/mins stirred 15-25 minute, and is mixed to fully; The 3rd step: the mixed solution and the ethanol of first step gained are poured in the mixer, after one hour, mixer is decelerated to 880 rev/mins with 1450 rev/mins speed stirrings; Pour white glue with vinyl into; Stirred 45 minutes with 1450 rev/mins speed again, observe the coating top layer, when the coating top layer evenly, when fine and smooth, smooth; Pour remaining 80% methyl alcohol into mixer again, stir and get zircon flour coating after 15 minutes.
Embodiment
Above-mentioned zircon flour coating is applied to the holy nation in Zhejiang load-transducing proportion control hydraulic multichannel valve body, weight 86KG, the foundry goods that uses this coating to cast, the unobstructed no clogging of runner; Smooth surface, basic zero defect.
