REDISPERSIBLE POLYMER POWDER MIXTURES FOR USE IN DRY-MIX FORMULATIONS HAVING IMPROVED PROPERTIES |
摘要 |
A mixture contains: (a) an acrylic core-shell redispersible polymer powder with a core polymer that is an acrylic having a glass transition temperature in a range of -40 to 50 degrees Celsius and a shell polymer that is alkali soluble and contains more carboxyl-group functionalities than the core polymer and containing a nucleating agent having a boiling point of 150-500 degrees Celsius and a water solubility of 3.5 weight-percent or less; and (b) a second redispersible polymer powder selected from acetate ethylene copolymer redispersible polymer powders and polymer powders of a blend of vinyl acetate ethylene copolymer and vinyl ester of versatic acid copolymer; where the concentration of (a) is more than 20 weight-percent and less than 100 weight-percent of the total combined weight of (a) and (b). The mixture can further contain: (c) a Portland cement; (d) alumina rich cement; and (e) calcium sulfate. |
