Lightweight waterproof coiled material and preparation method thereof
The invention relates to a light waterproof coiled material and a preparation method thereof, the light waterproof coiled material comprises a first resin layer and a second resin layer, thermal expansion microspheres are added in the first resin layer or the second resin layer, each thermal expansion microsphere comprises a core material and a shell, the core material comprises hydrocarbon and a liquid phosphorus-containing flame retardant, and the shell comprises an outer shell and an inner shell. The shell is an acrylate polymer obtained by polymerizing a polymeric monomer; the polymeric monomers comprise a first polymeric monomer and a second polymeric monomer, the first polymeric monomer is an acrylic phosphate monomer, and the second polymeric monomer is at least one of a nitrile monomer, a carboxyl acrylic monomer and a methacrylate monomer. The waterproof coiled material is arranged to be of a multi-layer resin layer structure, the specific thermal expansion microspheres are added in one layer, and the multiple flame retardant means that phosphorus-containing polymer shells of the thermal expansion microspheres and phosphorus-containing flame retardants are wrapped in the thermal expansion microspheres are utilized, so that the waterproof coiled material keeps the original flame retardance, the weight of the waterproof coiled material can be reduced, and the waterproof coiled material is suitable for being popularized and used. Meanwhile, the mechanical property is kept.
本发明涉及一种轻质防水卷材及其制备方法，包括第一树脂层和第二树脂层，第一树脂层或第二树脂层中添加有热膨胀微球，热膨胀微球包括芯材及外壳，芯材包含碳氢化合物和液态含磷阻燃剂，外壳为通过聚合单体聚合得到的丙烯酸酯类聚合物；聚合单体包括第一聚合单体和第二聚合单体，第一聚合单体为丙烯酸磷酸酯类单体，第二聚合单体为腈类单体、羧基类丙烯酸单体、甲基丙烯酸酯类单体中的至少一种。本发明通过将防水卷材设置成多层树脂层结构，并在其中一层中添加特定的热膨胀微球，利用热膨胀微球的含磷聚合物外壳和内部包覆含磷阻燃剂的多重阻燃手段，使得防水卷材不仅保持其原有阻燃性，而且能够减轻防水卷材的重量，同时又保持力学性能。
