涂膜防水屋顶的材料应用于涂膜防水屋顶的材料主要有各种涂料和胎体增强材料两大类。防水涂料的种类很多,根据其溶剂或稀释剂的类型可分为溶剂型、水溶型、乳液型等类;根据施工时涂料液化方法的不同则可分为热熔型、常温型等类。根据涂料硬化机理的不同:一类是用水或溶剂溶解后在基层上涂刷,通过水或溶剂蒸发而干燥硬化;另一类是通过材料的化学反应而硬化。一般有乳化沥青类、氯丁橡胶类、丙烯酸树脂类、聚氨酯类和焦油酸性类等,种类繁多。某些防水涂料(如氯丁胶乳沥青涂料)需要与胎体增强材料(即所谓的布)配合,以增强涂层的贴附覆盖能力和抗变形能力。目前使用较多的胎体增强材料为 0.1×6×4 或 0.1×7×7 的中性玻璃纤维网格布或中碱玻璃布、聚酯无纺布等。
There are two main types of materials used in the coating waterproof roof: various coatings and matrix reinforcement materials. There are many kinds of waterproof coatings. According to their solvents or diluents, they can be classified into solvent type, water soluble type and emulsion type. According to the different methods of coating liquefaction, they can be classified into hot-melt type and normal temperature type. According to the different hardening mechanism of coating: one is to brush on the base layer after dissolving with water or solvent, and then dry and harden through evaporation of water or solvent; the other is to harden through chemical reaction of materials. There are many kinds of emulsified asphalt, chloroprene rubber, acrylic resin, polyurethane and tar acid. Some waterproof coatings (such as chloroprene latex asphalt coating) need to be combined with matrix reinforcement materials (so-called cloth) to enhance the adhesion and deformation resistance of the coating. At present, most of the matrix reinforced materials are 0.1 × 6 × 4 or 0.1 × 7 × 7 neutral glass fiber gridding cloth or medium alkali glass cloth, polyester non-woven cloth, etc.
