Flexible reinforced composite material and preparation method thereof
The invention discloses a flexible reinforced composite material and a preparation method thereof, and belongs to the technical field of protection engineering. The preparation method of the flexiblereinforced composite material comprises the following steps of impregnating a woven fabric in a slurry padding solution, and drying to obtain a pretreated woven fabric; and then spraying a polyurea coating on the surface of the pretreated woven fabric by using a polyurea elastomer spraying technology to obtain the flexible reinforced composite material, wherein the slurry padding liquid comprisesthe following components including potato starch, corn native starch and waterborne polyurethane. The flexible reinforced composite material prepared by the method can reinforce reinforced concrete materials, has the advantages of flexibility, large-area curved surface coverage, light weight, convenience in storage and transportation, wide application range, quick reinforcement and repair, good anti-explosion and anti-penetration performance and the like, and is more suitable for anti-explosion reinforcement of special structures such as arch bridges.
本发明公开了一种柔性加固复合材料及其制备方法，属于防护工程技术领域。本发明所述的柔性加固复合材料的制备方法，包括以下步骤：将机织物在浆料浸轧液中浸渍、干燥得到预处理的机织物；随后利用喷涂聚脲弹性体技术在预处理的机织物的表面喷涂聚脲涂层，即得到柔性加固复合材料；其中浆料浸轧液的组分包括马铃薯淀粉、玉米原淀粉、水性聚氨酯。本发明制备得到的柔性加固复合材料可以对钢筋混凝土类材料加固，具有柔性、大面积曲面覆盖、重量轻、便于储存运输、适用范围广、快速加固抢修、抗爆与抗侵彻性能好等优点，更适合拱桥等特殊结构的抗爆加固。
