丙烯酸涂料复层凹凸花纹外墙饰面又称SB—2型复层凹凸花纹外墙饰面,简称《复层饰面》,是一项外墙饰面新技术。它是由底层,中间层和面层组成。底层为一般的混合砂浆抹灰,中间层做法是先用机械喷涂掺有107胶水的聚合胶泥,后用辊筒滚压,形成凹凸花纹,其凸出部分有一定的平整度,面层是滚涂二种不同颜色的丙烯酸涂料。丙烯酸系共聚高分子树脂,是溶剂性涂料,由上海南汇防水涂料厂生产,施工粘度控制为40～55秒/25℃(涂—4粘度计)如过稠可用二甲苯稀释。 Acrylic paint coating embossed pattern exterior wall finishes, also known as SB-2 type complex embossed pattern exterior wall finishes, referred to as “multilayer finishes”, is a new technology of exterior wall decoration. It consists of a bottom layer, a middle layer, and a surface layer. The bottom layer is a general mixed mortar plaster. The middle layer method is to use mechanical spraying with polymer cement mixed with 107 glue, followed by roller rolling to form a concave and convex pattern, the protruding part has a certain degree of flatness, the surface layer is rolled Apply two different colors of acrylic paint. Acrylic copolymerized polymer resin, is a solvent-based paint, produced by Shanghai Nanhui Waterproof Coating Factory. The construction viscosity is controlled at 40-55 seconds/25°C (coating- 4 viscometer). If too thick, it can be diluted with xylene.
