The invention relates to a marine propeller screw plugging protection method which comprises the following steps: step 1, after installation inspection of blades and a propeller hub of a propeller is finished, the installation completeness of screws in threaded holes is ensured; 2, a filler used for filling the threaded hole is prepared, the filler comprises EP-09 glue and cement, the EP-09 glue comprises a component A and a component B, and the mixing mass part ratio of the component A to the component B to the cement is 1: 0.72: 0.34-0.52; step 3, uniformly mixing the component A, the component B and the cement in proportion; and 4, the threaded hole is filled with the evenly stirred and mixed filler, and the threaded hole is completely blocked. The EP-09 glue and the cement are mixed and stirred to form the filler to fill the threaded hole, compared with traditional silica gel filling, the filler is firmer, and the waterproof performance and the corrosion resistance are improved.

    本发明涉及一种船用螺旋桨螺丝封堵保护方法,该方法包括以下步骤:步骤1、待螺旋桨的桨叶和桨毂安装报验结束后,确保螺纹孔内螺丝安装的完整性;步骤2、配置用以螺纹孔填充的填料,所述填料包括EP‑09胶和水泥,所述EP‑09胶包括A组分和B组分,所述A组分、B组分和水泥的混合质量份数比例为1:0.72:0.34‑0.52;步骤3、按比例将A组分、B组分和水泥混合均匀;步骤4、将搅拌混合均匀后的填料填充在螺纹孔内,将螺纹孔完全封堵。本发明通过EP‑09胶和水泥的混合搅拌形成填料对螺纹孔进行填充,相比与传统的硅胶等填充更加牢固,防水性能和耐腐蚀性能得以提升。
