Seawater swelling rubber material, preparation method thereof and seawater water stop strip
The invention relates to a seawater swelling rubber material and a preparation method thereof, and a seawater sealing strip, and relates to the technical field of materials, the seawater swelling rubber material comprises the following raw materials by weight: 90-115 parts of modified nitrile rubber, 40-65 parts of a water absorbing material, 1-4 parts of a vulcanizing agent, 0.5-2 parts of a vulcanization accelerator, 0.5-2 parts of an anti-aging agent, 1-4 parts of a softening agent, 5-10 parts of white carbon black, and 3-8 parts of zinc oxide; the modified butadiene-acrylonitrile rubber is obtained by performing microwave plasma treatment on butadiene-acrylonitrile rubber serving as a raw material; the water absorbing material is prepared from sodium polyacrylate and cationic starch as raw materials in a weight ratio of (90-100): (7-13). The rubber material capable of expanding when encountering seawater, provided by the invention, is suitable for underground waterproof engineering in coastal areas, has excellent salt resistance and mechanical properties, solves the problems of poor expansion rate and the like of the existing rubber material capable of expanding when encountering seawater in a high-salt environment, and has wide practical application value.
本发明涉及一种遇海水膨胀橡胶材料及其制备方法、海水止水条，涉及材料技术领域，以重量份数计，所述遇海水膨胀橡胶材料包括以下原料：改性丁腈橡胶90～115份、吸水材料40～65份、硫化剂1～4份、硫化促进剂0.5～2份、防老剂0.5～2份、软化剂1～4份、白炭黑5～10份和氧化锌3～8份；所述改性丁腈橡胶是以丁腈橡胶为原料经微波等离子体处理所得；所述吸水材料是以重量比为(90～100):(7～13)的聚丙烯酸钠和阳离子淀粉为原料制得。本发明提供了一种适用于沿海地区地下防水工程的遇海水膨胀橡胶材料，其具有优异的耐盐性和力学性能，解决了现有遇水膨胀橡胶材料在高盐环境中膨胀率差等问题，具有广泛的实际应用价值。
