Abstract

This article introduces results of investigations on Cu₂O concentration on release rate of antifouling composite coating for rubber, effects of fineness on ability to release Cu₂O of paint (fineness of paint increases, Cu₂O release speed of composite coating decreases), effects of period from composite coating preparation to start testing on ability of Cu₂O release. Besides, effects of anti-UV additive on ability of composite coating to withstand from UV-thermo-humidity complex was also investigated. Results show that Cu₂O concentration is 25 weight percent (wt. %), fineness of paint is 75-80 µm are suitable, period from composite coating preparation to time for being used is about 5 days for the best antifouling grade while ensuring mechanical properties of composite coating. Anti-UV additive of 1 wt. % is suitable for antifouling composite coating for rubber.
