The invention relates to the technical field of waterproof materials, and discloses a waterproof material for building exterior walls and a preparation method thereof.Epoxy soybean oil acrylate molecules contain active hydroxyl and a flexible fatty acid long-chain structure, and react with isocyanate groups and epoxy resin in sequence to form an interpenetrating cross-linked network structure; the dispersion effect in the system can be improved by the flexible long-chain structure, the interpenetration in the material is enhanced, and the density between the materials is improved; organic silicon in the organic silicon-fluorine chain extender forms a layer of compact silicon oxide protective film on the surface of a material to prevent water from permeating, and organic fluorine is hydrophobic, has good surface tension and can prevent water from permeating into the material, so that the waterproof performance of the building material is improved; the material prepared by the invention can be used for creating a skin type waterproof barrier for a building exterior wall material, has the characteristics of economy and environmental protection, and has a wide prospect of large-scale industrial application.
本发明涉及防水材料技术领域，且公开了一种建筑外墙用防水材料及其制备方法，环氧大豆油丙烯酸酯分子上含有活泼羟基和柔性脂肪酸长链结构，先后与异氰酸酯基团和环氧树脂反应，形成互穿交联网络结构，柔性长链结构可以增加在体系中的分散作用，增强材料内部的互相渗透，提高材料间的致密度；有机硅氟扩链剂中的有机硅通过在材料表面形成一层致密的硅氧化物保护膜来阻止水分渗透，有机氟本身是疏水性的，具有良好的表面张力，可以阻止水分浸入材料内部，从而提高建筑材料的防水性能；本发明制备的材料可为建筑外墙材料打造皮肤式的防水屏障，兼具经济和环保的特点，具有大规模工业应用的广阔前景。
