| titleOfInvention | A kind of polymer cement waterproof coating with good water resistance and preparation method |
| abstract | The invention relates to the technical field of water-based coatings, and provides a polymer cement waterproof coating with good water resistance and a preparation method. The polymer cement waterproof coating is composed of a liquid material and a powder material; the liquid material is composed of a composite rubber powder with a core-shell structure, a defoaming agent, a film-forming aid, a thickener, and water; the powder material is composed of silicon It is composed of acid salt cement, water reducing agent, wollastonite, quartz sand and heavy calcium carbonate. In the composite rubber powder of the core-shell structure, the shell layer is a polyurethane elastomer, the core layer is an ethylene-vinyl acetate copolymer rubber powder, and the p-hydroxystyrene segment forms a transition layer between the shell layer and the core layer. The method of the invention can endow the waterproof coating with good water resistance by adding the composite rubber powder of the core-shell structure, and can prevent the increase of the rigidity of the coating and the serious decrease of the elongation at break caused by the long-term immersion in water. |
