    摘要
  • 摘要:
      目的  为解决大型设备对船舶甲板表面的磨损问题，研制一种新型高耐磨甲板防滑涂层。
      方法  该涂层主要由底漆、防滑层及面漆组成；采用摩擦系数测试仪和滑动磨损测试仪分别进行涂层防滑、耐磨损性能测试，研究涂层在不同工况（干、湿、油态）下的磨损行为。
      结果  研究结果表明：研制的甲板防滑涂层具有高耐磨性及较高的摩擦系数；在不同工况条件下的摩擦系数随着磨损次数的增加逐渐降低，其中油态条件下涂层的摩擦系数最低，主要与航空煤油的润滑作用有关；涂层的磨损失重率随着磨损次数的增加呈上升的趋势；涂层的磨损机制主要为初期磨损阶段的磨粒磨损和稳定磨损阶段的粘着磨损。
      结论  研究成果不仅能够保证海洋结构物的服役安全性，还可为新型甲板防滑涂层的开发和应用提供理论依据。

     

    Abstract:
      Objectives  In order to solve the wear problem of ship decks caused by major equipment, a new highly wear-resistant anti-skid deck coating is developed.
      Methods  The coating is mainly composed of a primer, non-skid layer and topcoat. The non-skid wear performance of the coating was tested by sliding a wear tester. The friction and wear behavior of the coating under different working conditions(dry, wet and oily)was studied.
      Results  The results show that the friction coefficient of the coating under different working conditions decreases with the increase of the wear number, and the friction coefficient is lowest under oily conditions, which is mainly related to the lubrication of aviation kerosene; the wear loss rate of the coating increases with the increase of the wear number, and the wear mechanism is mainly abrasive wear in the initial wear stage and adhesive wear in the stable wear stage.
      Conclusions  The research results can not only guarantee service safety of the marine structure, but also provide theoretical basis for the development and application of new non-skid deck coatings.
