| The exploration and development of the Antarctic and Arctic regions requires the support of safe and reliable polar equipment and technologies. However, the preparation of polar ice-breaking coatings with high wear resistance and high toughness at low temperatures is still a huge challenge. In this work, we propose to use hydrogenated epoxy resin and amino silicone as reactive raw materials, and rely on Si==C and Si—O—Si bonds to form a soft and hard block structure during cross-linking and curing stage of the coating, so as to effectively improve the low temperature brittleness of epoxy resin and reduce the surface tension. High-hardness inorganic powders such as SiC and basalt modified with KH560 and flexible rent-reducing fillers such as polytetrafluoroethylene powders are added to the modified resin to prepare a polar icebreaker coating with low temperature resistance, high strength and toughness. At the same time, we pay attention to the current situation that such products have only application cases and no standards. From the perspective of actual and potential application of products, some new indicators and detection methods are added and discussed. The low temperature service performance of the coating was evaluated by the adhesion circle test, impact resistance test and flexibility test at ‒50 ℃. The low temperature wear resistance of the coating was evaluated by the pendulum rod hardness test and wear resistance test under ‒50 ℃. The durability of the coating was evaluated by neutral salt spray resistance test, artificial accelerated aging test, the change of adhesion and morphology (SEM) before and after each 3 000 h test. The anti-icing performance of the coating was characterized by the contact angle tester and the icing force tester.The hardness and wear resistance of the coatings increased gradually with the increase of the pigment to varnish base ratio, while the contact angle, icing force, salt spray resistance and pull-off adhesion of the coating increased first and then decreased. Among them, the hardness of the coating in group c is 0.553, the wear resistance is 1 000 g/750 r, the wear is 16mg, the contact angle is about 98.8°, the ice force is 32 N, indicating that the overall performance is the best. Artificial accelerated aging and salt spray SEM morphology analysis also showed that the c-group coating had the best durability.The epoxy-polysiloxane system prepared from hydrogenated epoxy resin and amino silicone can effectively avoid the low temperature brittleness of epoxy while maintaining high hardness. Under the low temperature service, the coating exhibits high wear resistance, durability, good anti-icing performance, high low-temperature adhesion, good impact resistance, good flexibility, and good anti-icing performance. It can be seen that under the synergistic effect of high-hardness inorganic powder and flexible drag-reducing filler, the coating can effectively improve the wear resistance, hardness and other properties of the coating at low temperature, and then can meet the protection needs of ships in the ice-breaking area under the low temperature environment. |
