The invention relates to the technical field of building construction, in particular to a rigid polyurethane foam roof waterproof heat preservation process which comprises the following steps that S1,cleaning and drying a building roof; S2, laying a slope making layer on the roof; S3, spraying a polyurethane rigid foam spraying material on the slope making layer, and foaming the spraying materialat room temperature to form a heat preservation layer; wherein the rigid polyurethane foam spraying coating is prepared from a composite material and polyisocyanate according to the weight ratio of 1: (1 to 1.5); the composite material comprises the following components in parts by weight: 30-50 parts of sucrose polyether polyol; 40-60 parts of organic amine polyether polyol; 20-40 parts of aromatic polyester polyol; 3-13 parts of a stabilizer; 6-10 parts of a catalyst; and 30-40 parts of a fluorodichloroethane foaming agent. The invention has the advantages that: the polyurethane rigid foambody has better ageing resistance, cement mortar does not need to be poured for protection, the construction process is simpler and more convenient, the quality of the roof is better, and the exterior decoration of the roof is more attractive.
本发明涉及建筑施工的技术领域，具体涉及一种聚氨酯硬泡体屋面防水保温工艺，其包括以下步骤：S1.建筑屋面清理并干燥；S2.在屋面铺设找坡层；S3.在找坡层上喷涂聚氨酯硬泡体喷涂料，室温发泡形成保温层；聚氨酯硬泡体喷涂料包括按重量比为1:(1‑1.5)的组合料与多异氰酸酯；组合料包括以下重量份数的组分：蔗糖聚醚多元醇30‑50份；有机胺聚醚多元醇40‑60份；芳烃聚酯多元醇20‑40份；稳定剂3‑13份；催化剂6‑10份；一氟二氯乙烷发泡剂30‑40份。本发明具有聚氨酯硬泡体抗老化性能较佳，无需再浇注水泥砂浆以作为保护，施工工序较为简便，同时还使得屋面的质量较佳，屋面外饰也较为美观的效果。
