Spraying type polyurethane waterproof coating as well as preparation method and construction method thereof
The invention discloses a spraying type polyurethane waterproof coating as well as a preparation method and a construction method thereof. The technical problem that a polyurethane waterproof coating in the prior art cannot have ultrahigh strength and ultrahigh toughness at the same time is solved. The polyurethane waterproof coating is prepared from the following raw materials in parts by weight: 136-170 parts of polyether polyol; 0 to 20 parts of polyester polyol; 34 to 65 parts of isocyanate; 15 to 25 parts of a solvent; 8.8 to 11 parts of pigment; 10 to 12 parts of filler; 1.5 to 3 parts of a chain extender; 0.8 to 1 part of a defoaming agent; 1.4 to 1.8 parts of a thixotropic agent; 0.4 to 0.6 part of a dispersing agent; and 0.15 to 0.35 part of a catalyst. The high-solid-content waterproof material has the characteristics of ultrahigh tensile strength, ultrahigh toughness and high solid content, is suitable for waterproofing of important projects such as railways, highways, bridges, tunnels, dams and the like, and is high in construction efficiency.
本发明公开了一种喷涂型聚氨酯防水涂料及其制备方法和施工方法，解决了现有技术中的聚氨酯防水涂料不能同时具备超高强和超高韧性的技术问题。所述聚氨酯防水涂料的制备包括下述重量份的原料：聚醚多元醇136‑170份；聚酯多元醇0‑20份；异氰酸酯34‑65份；溶剂15‑25份；颜料8.8‑11份；填料10‑12份；扩链剂1.5‑3份；消泡剂0.8‑1份；触变剂1.4‑1.8份；分散剂0.4‑0.6份；催化剂0.15‑0.35份。本发明具有超高的拉伸强度、超高韧性、高固体含量的特性，适用于铁路、公路、桥梁、隧道、水坝等重要工程的防水，施工效率高。
