Building waterproof polymer coating capable of being used at low temperature and preparation method thereof

Abstract

The invention discloses a building waterproof polymer coating capable of being used at low temperature and a preparation method of the building waterproof polymer coating, and belongs to the technical field of building waterproofness. Self-synthesized modified mica / ferroferric oxide serves as filler, and the surface of the modified mica / ferroferric oxide contains a network structure of castor oil base and isocyanate group; the modified mica / ferroferric oxide can be fixed in the building waterproof polymer coating through polymerization reaction, and the flexible long chain of castor oil can endow enough toughness; according to the modified mica / ferroferric oxide disclosed by the invention, the mica is of a natural layered sheet structure, and after the mica is compounded with the ferroferric oxide, the ferroferric oxide can fill tiny gaps among the sheet structures of the mica, so that the porosity of a barrier layer is reduced, and the waterproof barrier is more complete; the layered structure of mica and the rigid structure of ferroferric oxide can improve the overall mechanical strength of the coating.
