Abstract
The invention discloses a casting coating modified synergist. A permanent mold casting coating modified synergist contains materials of sodium borate, phosphoric acid, sodium chloride, hydrochloric acid, silica sol and the like. The casting coating modified synergist can improve the suspension property of a high specific gravity aggregate effectively, improve the rheological property of coating remarkably, lower the gas-forming property, and improve the high temperature intensity of a coating layer and the mold stripping property of a casting.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of modified synergist of casting coating.
Background technology
The cast paint that existing high specific gravity aggregate (as zirconium English powder, chromite powder, electro-corundum powder) is base-material, for obtaining good suspendability, mostly being all or part of employing efficiently has base suspending agent (as CMC, polyacrylamide, polyvinyl alcohol etc.).This kind of suspending agent is large due to gas forming amount, is easy to make foundry goods produce pore, is thus that application is restricted in permanent mold casting.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, a kind of modified synergist of casting coating is provided, effectively can improve high specific gravity aggregate coating suspension.
Modified synergist of casting coating provided by the invention, the percentage of its component and each component is as follows: Boratex: 2 ~ 15%; Phosphoric acid: 2 ~ 12%; Sodium chloride 0 ~ 12%; Hydrochloric acid 0 ~ 10%; Ludox 0.5 ~ 5%; Yu Weishui.
Modified synergist of casting coating provided by the invention, its beneficial effect is, effectively can improve high specific gravity aggregate suspension, and can improve the rheological characteristic of coating significantly, reduces gas-forming property, improves the elevated temperature strength of coating and the release property of foundry goods.
Detailed description of the invention
Below in conjunction with an embodiment, modified synergist of casting coating provided by the invention is described in detail.
Embodiment
The modified synergist of casting coating of the present embodiment, manufacturing process is as follows: in die spinning alloy pipe, adopts following formula to mix coating processed: Boratex: 4%; Phosphoric acid: 6%; Sodium chloride 8%; Hydrochloric acid 6%; Ludox 2%; Yu Weishui.
Claims (1)
1. a modified synergist of casting coating, is characterized in that: the percentage of its component and each component is as follows: Boratex: 2 ~ 15%; Phosphoric acid: 2 ~ 12%; Sodium chloride 0 ~ 12%; Hydrochloric acid 0 ~ 10%; Ludox 0.5 ~ 5%; Surplus is water.
