Building waterproof exterior wall water-based paint and spraying method thereof
The invention discloses building waterproof exterior wall water-based paint and a spraying method thereof, and relates to the technical field of water-based paint. The spraying method comprises the following steps: reacting a polyurethane emulsion with an acrylate monomer to obtain a composite emulsion, treating nano silicon dioxide with a silane coupling agent to obtain modified nano silicon dioxide, modifying glucan with cholesterol, reacting modified glucan with polylactic acid to obtain modified polylactic acid, sequentially weighing the composite emulsion, water, a composite additive, themodified nano silicon dioxide and the modified polylactic acid, mixing the composite emulsion, the water and the composite additive, and respectively conducting mixing with the modified nano silicondioxide and the modified polylactic acid to obtain a first primer, a second primer, a first finishing coat and a second finishing coat; and sequentially smearnig the first primer, the second primer, the first finishing coat and the second finishing coat so as to complete spraying. The building waterproof exterior wall water-based paint prepared by the invention has excellent waterproof performance.
本发明公开了一种建筑防水外墙水性漆及其喷涂方法，涉及水性漆技术领域。本发明先将聚氨酯乳液与丙烯酸酯单体反应后制得复合乳液，然后将纳米二氧化硅经硅烷偶联剂处理后制得，并将葡聚糖先经胆固醇改性后再与聚乳酸反应制得改性聚乳酸，最后，依次称取复合乳液、水、复合添加剂、改性纳米二氧化硅和改性聚乳酸，将复合乳液、水、复合添加剂混合后，再分别与改性纳米二氧化硅、改性聚乳酸混合，制得一号底漆、二号底漆、一号面漆和二号面漆，将一号底漆、二号底漆、一号面漆和二号面漆依次涂抹后，即完成喷涂。本发明制备的建筑防水外墙水性漆具有优异的防水性能。
