Problems solved by technology

Although the rubber materials used in current ships can meet the general needs of ships, many shipowners want to prevent damage to the rubber materials used in ship equipment during ship operation for the sake of safe operation of ships. The installation of materials not only increases the operating cost, but also restricts the safe operation of some ships that need to perform special tasks for a long time

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a marine high-performance rubber material. Background technique [0002] As we all know, regardless of mechanical properties, heat resistance, corrosion resistance and disaster protection, the rubber materials used in ships play a vital role in maintaining the normal operation of ships. In specific applications, rubber materials must be resistant to sunlight , aging and acid and alkali erosion, and can withstand severe weather conditions such as high temperature and severe cold, and can still temporarily guarantee its normal operation in the case of accidental disasters. [0003] The working environment of rubber materials in ships is very harsh. It is necessary to ensure good wear resistance, seawater corrosion resistance, and oil resistance and high temperature resistance. Although the rubber materials used in current ships can meet the general needs of ships, many shipowners w...
