Abstract
The invention discloses a paint formula, particularly discloses a lost foam casting-use paint formula and a technology method thereof. The lost foam casting-use paint formula comprises the following components: 45-65% of bauxite, 1-5% of silica sol, 20-50% quartz powder, 1-5% of phenolic resin, 1-5% of white emulsion, 1-5% of sodium bentonite, 0.1% of isopropanol, 0.1% of JFC and 0.3-0.5% of CMC. The technology method of the lost foam casting-use paint formula comprises the following steps: 1, in the ratio of paint powder to water of 1:0.7, putting the paint powder and the water into a stirrer for stirring for 1-1.5 hours, then measuring baume degree, and controlling the baume degree between 65 and 70 through dilution with water; 2, according to production requirements, dip-coating for two times or three times; and 3, the thickness of a coating layer being 1-2 mm. White molds of the technology method have good wettability, good coating and hanging property, high strength and good air permeability.
Description
Technical field
The present invention relates to a kind of prescription of coating, particularly relate to a kind of coating for dispellable mould casting prescription and process thereof.
Background technology
The coating for dispellable mould casting prescription is relatively poor with white mould wellability in the prior art, and being coated with property is relatively poor, and intensity is low, and gas permeability is relatively poor.
Summary of the invention
In order to address the above problem, the invention provides a kind of white mould wellability better, being coated with property is better, intensity is high, gas permeability preferably coating for dispellable mould casting prescription and process thereof.

Be preferably, this coating for dispellable mould casting formula components is as follows:
Bauxite 55%, Ludox 5%, silica flour 24.4%, phenolic resins 5%, white glue with vinyl 5%, sodium bentonite 5%, isopropyl alcohol 0.1%, JFC:0.1%, CMC:0.4%.
The process of coating for dispellable mould casting prescription of the present invention is characterized in that: finish in accordance with the following steps:
One, in the ratio of proportioning 1 ︰ 0.7 of coating powder and water, put into agitator, stir and measure Baume degrees after 1-1.5 hour, Baume degrees makes it be controlled at 65-70 by thin up;
Two, according to production requirement, can dip-coating two times or three times;
Three, the thickness of coating is that thickness is 1～2mm.
Beneficial effect of the present invention compared with prior art.
1, owing to adding in right amount refractory aggregate, increased the gas permeability of coating.
2, this coating refractory temperature can reach 〉=1700 ℃.
3, have good thixotropy, rheological characteristic and suspension.
4, good permeability, gas forming amount is little.
5, anti-stick sand, burning into sand, elephant skin, vein, any surface finish, easily sand removal.
6, normal temperature strength is high, and coating does not ftracture, and is non-foaming.
7, environmental protection is without free sio
