Abstract

The present invention provides a marine pumping corrosion protection layer and a spray coating method thereof, wherein the marine pumping corrosion protection layer comprises a primer layer, an intermediate paint layer and a top coat layer, the primer layer is prepared by mixing an epoxy resin and a curing agent according to a volume ratio of 3:2, the intermediate paint layer is prepared by mixing a polyamide epoxy paint and a curing agent according to a volume ratio of 3:1, the top coat layer is prepared by mixing a polyurethane surface paint and a curing agent according to a volume ratio of 6:1, 0.1-0.3% of a coupling agent and 10-20% of a filler are respectively mixed in the primer layer, the intermediate paint layer and the top coat layer, the coupling agent is vinyl triethoxysilane or isopropyl triisostearyl titanate, and the filler is one or a plurality of materials selected from titanium dioxide powder, corundum powder, wollastonite powder, carbon black powder and quartz powder. According to the present invention, the pollution of the marine pumping corrosion protection layer on the environment can be solved so as to further increase the marine pumping work efficiency.

Description

technical field [0001] The invention relates to the field of medium delivery pumps, in particular to a corrosion protection layer for marine pumps and a spraying method thereof. Background technique [0002] In addition to the strong electrochemical corrosion of seawater, marine pumps are also fouled and corroded by marine organisms. There are a large number of microorganisms in seawater, and some microorganisms are easy to attach to the steel surface and form biofilm. Biofilm is a microbial community structure that contains aerobic and anaerobic bacteria. As the immersion time increases, on the surface of metals, especially steel structures, biofilms will gradually change from aerobic microorganisms to anaerobic microorganisms. as the subject. Many marine organisms and microorganisms are adsorbed on the surface of marine pumps or other metal structures in direct contact with seawater, and grow and reproduce. Especially in warm sea areas and in spring and summer, these ha...
