Graphite and graphene composite modified polyurethane waterproof coating film and preparation method thereof
The invention belongs to the technical field of waterproof and anticorrosive materials, and particularly relates to a graphite and graphene composite modified polyurethane waterproof coating film and a preparation method thereof. According to the technical scheme, the graphite and graphene composite modified polyurethane waterproof coating film comprises a coating film layer and a covering layer, and the coating film layer is a continuous film layer formed after graphene modified polyurethane emulsion is coated; the covering layer is a compact graphite solid powder layer formed by uniformly spreading and rolling expandable graphite; and the covering layer and the coating layer are combined together. According to the graphite and graphene composite modified polyurethane waterproof coating film and the preparation method thereof provided by the invention, the coating film has excellent weather resistance and ultraviolet resistance and can be exposed for construction, so that the construction cost is saved; the coating film has flame retardance, and the fire safety of buildings is improved.
本发明属于防水防腐材料技术领域，具体涉及一种石墨和石墨烯复合改性聚氨酯防水涂膜及其制备方法。本发明的技术方案如下：一种石墨和石墨烯复合改性聚氨酯防水涂膜，包括涂膜层和覆盖层，所述涂膜层为石墨烯改性聚氨酯乳液经涂布后形成的连续膜层；所述覆盖层为由可膨胀石墨经均匀扬撒和碾压形成的致密石墨固体粉末层；所述覆盖层与所述涂膜层结合在一起。本发明提供的石墨和石墨烯复合改性聚氨酯防水涂膜及其制备方法，具有优异的耐候、耐紫外线性能，能外露施工，节约施工成本；该涂膜具有阻燃性,提高了建筑物的消防安全度。
