Abstract

The invention relates to ship ballast tank coating which part by weight comprises 30-60 portions of epoxy resin, 5-15 portions of coumarone indene resin, 10-20 portions of curing agent, 30-50 portions of pigment and filler, 3-5 portions of auxiliary agent and 5-10 portions of solvent, based on the total weight of the ship ballast tank coating as the reference. The coumarone indene resin adopted by the ship ballast tank coating is thermoplastic non-reaction resin, has excellent acid-alkali resistance and no harm to human body; the coumarone indene resin is used to replace the epoxy coal pitch in the prior art; thereby, the acid-alkali resistance of the coating is improved; the ship ballast tank coating adopts the epoxy resin which has good acid-alkali resistance; meanwhile, the cross linking degree of the paint film can be improved greatly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating for ballast water tanks of ships, which is an anti-corrosion coating applied to water tanks of ships. Background technique [0002] At present, most of the anti-corrosion coatings for ballast water tanks of ships use epoxy coal tar pitch anti-corrosion coatings containing a large amount of coal tar pitch. The discoloration of the paint, especially the coal tar pitch contains a large amount of strong carcinogens such as benzoquinone and its derivatives, which brings certain harm to the paint production workers and construction personnel. Besides, the International Marine Convention on the Environment has explicitly banned the use of water tanks in 2008. Discharge of water containing bituminous components into the sea is not permitted. Contents of the invention [0003] The purpose of the present invention is to provide a long-lasting, non-toxic and medium-resistant coating for...
