Non-asphalt-based spraying quick-setting waterborne polyurethane waterproof coating and preparation method thereof
The invention belongs to the technical field of coatings, and discloses a non-asphalt-based spraying quick-setting waterborne polyurethane waterproof coating and a preparation method thereof. The waterproof coating comprises a component A and a component B, wherein the component A comprises the following raw materials: deionized water, a composite waterborne polyurethane dispersion, a pigment filler, a flame retardant, a freeze-thaw stabilizer, a pH regulator, a defoaming agent, a wetting agent, a dispersing agent, a coalescing agent, a thickening agent, an adhesion promoter, a bactericidal preservative and an anti-aging agent; and the component B is a coagulation accelerator and consists of an inorganic metal salt solution and an additive. The waterproof coating can reach more than 500% of elongation at break, tensile strength exceeding 2MPa, B1-level flame retardant property, ultralow temperature resistance and freeze-thaw stability, can be solidified after 2-4 seconds after being sprayed and constructed to a thickness of 0.5-5mm at one time, greatly saves construction time and construction cost, and has physical properties comparable to solvent type polyurethane and higher environmental protection performance.
本发明属于涂料技术领域，公开了一种非沥青基喷涂速凝水性聚氨酯防水涂料及制备方法。本发明的防水涂料包括A组分和B组分，其中A组分的原料组成为去离子水，复合水性聚氨酯分散体，颜填料，阻燃剂，冻融稳定剂，pH调节剂，消泡剂，润湿剂，分散剂，成膜助剂，增稠剂，附着力促进剂，杀菌防腐剂，抗老化剂；B组分为促凝剂，由无机金属盐溶液和外加剂组成。该防水涂料可达到500％以上的断裂延伸率以及超过2MPa的拉伸强度，B1级阻燃性能以及耐超低温和冻融稳定性，一次性喷涂施工到0.5～5mm厚度，2～4s后即可凝固，大量节省了施工时间和施工费用，且具有可媲美溶剂型聚氨酯的物理性能和更高的环保性能。
