Preparation and Properties of a Novel Ash-calcium-powder Internal Wall Coating

摘要

A kind of novel ash-calcium-powder internal wall coating was successfully prepared. The stability problem was resolved by adding the stabilizer synthesized in our own laboratory. The effect of vinyl acetate ester-ethylene (VAE) emulsion contents on the property of scrub resistance was studied. And the effect of ash-calcium-powder contents on the property of scrub resistance and contrast ratio were discussed. The results indicate that the scrub resistance increase with increasing the content of ash-calcium-powder or VAE emulsion. Also the scrub resistance is effected by the filming time. And it is shown that the longer, the better the scrub resistance.
